The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. The technical solutions between the embodiments can be combined with each other, but must be based on the fact that those skilled in the art can realize the technical solutions, when the technical solutions are contradictory or cannot be realized, the technical solutions should be considered to be absent, and the technical solutions are not within the scope of protection claimed by the present invention.

At present, most of intelligent switches with key types are provided with characters or patterns printed on the keys in advance to prompt key functions, and if a user changes the corresponding functions of the keys, the keys need to be synchronously replaced, which brings inconvenience to the user and causes waste. To solve this problem, referring to fig. 1-24, the present invention provides an intelligent switch 100 that is specifically illustrated. As shown in fig. 1 to 5, the smart switch 100 includes a panel base 1, a pressing part 2, and a display device 10; the pressing part 2 is connected to the panel base 1, and the pressing part 2 comprises a plurality of keys 21; the display device 10 includes a plurality of display screens 101 corresponding to the keys 21 one by one, and each display screen 101 is disposed on the panel substrate 1 and is used for displaying key information corresponding to the key 21; the intelligent switch 100 provided by the invention can display the corresponding information of each key 21 through the display screen 101, and a user can change the display content of the display screen 101 to adapt to the change of key functions, so that the problem that patterns or characters need to be changed by changing the keys 21 in the prior art is solved. It should be understood that the number of the display screens 101 is equal to the number of the keys 21, and the positions of the display screens 101 correspond to the positions of the keys 21, for example, each display screen 101 may be disposed near an end of each key 21. The advantage of using multiple independent display screens 101 over using a single display screen 101 is that the effective utilization of the display area of a single display screen 101 is improved, the white space is reduced, and when one of the display screens 101 is damaged, the display screen 101 can be replaced independently, thereby saving maintenance costs.

In addition, as shown in fig. 1 to 5, one end of each key 21 of the intelligent switch 100 provided by the invention is connected to form a connection end 22 of the pressing portion 2, and the other end of each key 21 far away from the one end is separated from each other to form a pressing end 23 of the pressing portion 2, so that when one key 21 performs a pressing motion, other keys 21 do not follow the motion, and each key 21 provides a reset force to each other through the connection end 22, and each display screen 101 is disposed close to the connection end 22. The keys 21 may be integrally connected to each other at one end, or the keys 21 may be fixedly connected to each other by a fixing piece, or may be connected in other forms. The keys 21 provide a restoring force to each other, which is understood to mean that the ends of the keys 21 are connected by the connecting end 22, when one of the keys 21 is pressed, the key 21 drives the connecting end 22 to generate a movement trend, and the connecting end 22 is kept stationary under the connection action of the other keys 21, so that the connecting end 22 and the pressed key 21 are deformed, and a restoring force is generated. The display screens 101 are disposed near the connection end 22, which means that the display screens 101 are disposed near the end of each key 21 in a one-to-one correspondence.

According to the intelligent switch 100 provided by the invention, the end parts of the keys 21 are connected with each other, so that the intervals among the keys 21 are kept consistent, and the position corresponding relation between the keys 21 and the display screen 101 is more accurate; meanwhile, since the end parts of the keys 21 are connected, reset force can be provided between the keys 21, and an additional reset structure is not needed, so that the structure is simplified; in addition, the keys 21 are connected, so that the keys 21 cannot shake, and cannot be loosened and collapsed, and the pressing hand feeling is improved.

According to an embodiment of the present invention, as shown in fig. 9 and 13, the intelligent switch 100 further includes a bottom case 3 provided with a mounting hole 31, the mounting hole 31 is used for mounting externally, and the pressing portion 2 covers the mounting hole 31; when the user installs the intelligent switch 100, the user only needs to detach the pressing part 2 to expose the installation hole 31, and then the installation screw 32 can be connected into the cassette of the wall through the installation hole 31, so as to fix the intelligent switch 100 to the wall; the installation need not to pull down panel base member 1, has protected inside circuit board 5, avoids circuit board 5 to follow panel base member 1 and has the risk of dropping and breaking after being pulled down.

Since the intelligent switch 100 provided by the invention can be externally installed only after the key 21 is disassembled, the key 21 needs to have the characteristic of easy disassembly, and each key 21 cannot be disassembled one by one during the disassembly so as to avoid the connection end 22 connected with each key 21 from being broken off. Based on this, the embodiment of the invention provides a row of keys 21 which are convenient to disassemble and assemble, and the row of keys 21 comprise a plugging structure 241, an abutting structure 242 and a movable clamping structure 243, and the three structures are mutually matched so as to realize the easy disassembly and assembly effect of the keys 21. As shown in fig. 6, 3 and 9, the connection end 22 of the pressing portion 2 is provided with the plugging structure 241, the panel base 1 is provided with the plugging position 11, the plugging structure 241 is plugged into the plugging position 11 so as to be limited by the plugging position 11 to move towards a fifth direction opposite to the direction in which the key 21 is pressed, wherein fig. 5 is a top view of the intelligent switch 100, fig. 6 is a step-a cross-sectional view in fig. 5, and it should be noted that the plugging structure 241, the abutting structure 242 and the movable clamping structure 243 are not on the same vertical plane (as can be seen in fig. 3), and fig. 6 concentrates the three on the same cross-section by means of step-sectioning, so that the structure can be more intuitively displayed. The fifth direction is the vertically upward direction in fig. 6, which has been marked in fig. 6. The plugging structure 241 may be a plug tongue, a latch, a plugboard or other plugging structure. The plugging direction of the plugging structure 241 may be a horizontal direction in fig. 6, an upward inclined direction, or a downward inclined direction, and the plugging position 11 may abut against the upper surface of the plugging structure 241 during the movement of the key 21, so as to limit the movement of the plugging structure 241 toward the fifth direction.

The connection end 22 of the pressing portion 2 is provided with the abutting structure 242 toward a second direction, the abutting structure 242 is disposed between the plugging structure 241 and the pressing end 23, the second direction is the same as the direction in which the key 21 is pressed, the second direction is a vertically downward direction in fig. 6, and the second direction is already marked in fig. 6; the panel base 1 has a supporting and limiting structure 12 at a position corresponding to the abutting structure 242, the abutting structure 242 abuts against the supporting and limiting structure 12, the supporting and limiting structure 12 can limit the plugging structure 241 to separate from the plugging position 11, wherein when the abutting structure 242 abuts against the supporting and limiting structure 12, the two cooperate to limit the key 21 to move horizontally, so as to limit the plugging structure 241 to separate from the plugging position 11 rightward. As shown in fig. 7, which is a schematic diagram of the pressing end 23 of the pressing portion 2 when the pressing end 23 is pressed, the pressing end 23 moves with the supporting and limiting structure 12 as a pivot, and the key 21 may pivot with the supporting and limiting structure 12 as a pivot, so as to drive the pressing end 23 to move; or the key 21 deforms by taking the supporting and limiting structure 12 as a fulcrum, and the pressing end 23 is driven to move downwards by the deformation of the key 21, so that the detecting piece 52 is triggered. The movable clamping structure 243 is disposed at the position of each key 21 near the pressing end 23 toward the second direction, the movable clamping structure 243 is clamped to the panel base 1, the pressing end 23 of the key 21 can be restricted from being separated from the panel base 1 toward the fifth direction, and the movable clamping structure 243 can move toward the second direction.

As shown in fig. 8, fig. 8 is a schematic diagram illustrating a disassembly process of the pressing portion 2 in fig. 6, when the pressing portion 2 is disassembled from the panel base 1, a user may first break the pressing end 23 upward, so that each movable clamping structure 243 is separated from the panel base 1, the pressing portion 2 may rotate counterclockwise based on the whole plugging structure 241, and when the rotation angle reaches a certain value, the abutting structure 242 is separated from the supporting and limiting structure 12, so that the pressing portion 2 loses the limitation of the supporting and limiting structure 12, and the plugging structure 241 can be separated from the plugging position 11 rightward. The whole disassembly process is simple and quick, and is suitable for the characteristics that the intelligent switch 100 needs to be installed outwards after the pressing part 2 is disassembled. In addition, compared with the prior art that each key 21 is provided with a hole site and is rotationally connected with the panel substrate 1, the scheme of matching the plugging structure 241 with the abutting structure 242 is adopted in the embodiment, so that the pressing part 2 can be integrally detached from the panel substrate 1 without detaching the keys 21 one by one, and the connection ends 22 for connecting the keys 21 are prevented from being broken off, therefore, the detaching scheme of the pressing part 2 provided by the embodiment is more suitable for the continuous row key 21 structure of the invention.

Correspondingly, the installation process of the pressing portion 2 is opposite to the detachment process, as shown in fig. 8, when the pressing portion 2 is installed on the panel substrate 1, the plugging structure 241 may be first obliquely inserted into the plugging position 11 toward the lower left, and then the whole pressing portion 2 is turned clockwise based on the plugging structure 241, so that the abutting structure 242 abuts against the supporting and limiting structure 12, and finally the pressing end 23 is pressed downward, so that the movable clamping structure 243 is clamped on the panel substrate 1, thereby completing the installation. The whole installation process is fast and convenient, and is suitable for the characteristic that the pressing part 2 needs to be installed on the panel base body 1 after the intelligent switch 100 is installed on a wall.

Further, as shown in fig. 8, in the process of installing and detaching the pressing part 2, when the pressing part 2 is tilted, the left end of the pressing part 2 abuts against the transparent cover plate 4, so as to ensure that the pressing part 2 can be smoothly detached and installed, as shown in fig. 6, a certain gap is provided between the left end of the pressing part 2 and the transparent cover plate 4, and the gap reserves a space for the pressing part 2, so that in the process of installing and detaching the pressing part 2, when the pressing part 2 is tilted, the transparent cover plate 4 does not interfere with the pressing part 2.

According to an embodiment of the present invention, as shown in fig. 7 and 6, the plugging position 11 abuts against a surface of the plugging structure 241 facing the fifth direction, when the pressing end 23 is pressed, the pressing end 23 moves with the supporting and limiting structure 12 as a fulcrum, and the plugging position 11 gives an abutting force to the plugging structure 241 facing the second direction, so that the pressing end 23 generates a restoring force. The pressing portion 2 corresponds to a seesaw structure using the supporting and limiting structure 12 as a fulcrum, the plugging position 11 limits the left end of the pressing portion 2 to move upwards through the plugging structure 241, when the pressing end 23 located at the right end of the pressing portion 2 receives the pressing force, the pressing end 23 moves downwards, the pressed key 21 is bent and deformed due to the fact that the left end of the pressing portion 2 is limited to move upwards, other keys 21 which are not pressed remain in an initial state, the key 21 deforms to generate a reset force, and the reset force is set to be a first reset force. Next, since the keys 21 are connected to each other via the connection terminals 22, the keys 21 can also supply a restoring force to each other, which is set to a second restoring force. In addition, the pressing of the key 21 against the detecting member 52 causes the detecting member 52 to generate a reaction force to the key 21, which is set as the third restoring force. When the pressing force is removed, the pressed key 21 is reset under the combined action of the first reset force, the second reset force and the third reset force, so that an additional reset structure is not required for the key 21, and the structure is simplified.

Further, the detecting member 52 is selected from one of a tact switch, a micro switch, a detecting switch, a membrane switch, and a hall switch, and in a preferred embodiment, the detecting member 52 is a tact switch.

Further, as shown in fig. 6, the detection member 52 is disposed on a surface of the circuit board 5 facing the panel substrate 1, the key 21 is disposed with a trigger post 211 facing the detection member 52, the key 21 triggers the detection member 52 through the trigger post 211, when the key 21 is not pressed, the detection member 52 is still pressed by the trigger post 211 to generate a small compression amount, the compression amount is insufficient to trigger the detection member 52, but a pretightening force can be provided for the key 21, so that the key 21 cannot be loosened and collapsed, and the pressing hand feeling is tighter; and the compression quantity can enable the trigger post 211 and the detection piece 52 to be in a contact state all the time, so that a gap between the trigger post 211 and the detection piece 52 is eliminated, further, the idle stroke of the key 21 is eliminated, and the trigger sensitivity of the key 21 is improved. Further, as shown in fig. 3, 6 and 9, the plugging structure 241 includes a plug tongue disposed by the connection end 22 toward a third direction, the plug tongue is plugged into the plugging position 11, and is limited by the plugging position 11 to move toward the fifth direction; the third direction is the direction in which the pressing end 23 of the pressing portion 2 faces the connecting end 22, and the third direction is the horizontal left direction in fig. 6, and the third direction is already marked in fig. 6 and 3.

The number of the abutting structures 242 is two, the two abutting structures 242 are arranged at intervals along the first direction, and in the first direction, the two abutting structures 242 are located between the two plugging structures 241. In addition, each key 21 is provided with one movable clamping structure 243 and one trigger post 211, and each movable clamping structure 243 and each trigger post 211 are arranged along the first direction.

The first state is a state in which the pressing portion 2 is disengaged, the second state is a state during the installation of the pressing portion 2, and the third state is a state in which the installation of the pressing portion 2 is completed. In the second state, the plugging structure 241 of the pressing portion 2 is obliquely inserted into the plugging position 11 toward the lower left, the clamping interface 2442 of the clamping rotating structure 244 is abutted against the second rotating shaft 14, and the movable clamping structure 243 is not clamped into the panel substrate 1 yet; at this time, since the pressing portion 2 is integrally inclined, the opening direction of the card interface 2442 is exactly vertical downward, and when the pressing portion 2 rotates downward based on the plugging structure 241, the movement direction of the card interface 2442 is exactly consistent with the opening direction of the card interface 2442, so that the card interface 2442 can be smoothly snapped into the second rotating shaft 14; subsequently, the movable clamping structure 243 is clamped into the first clamping position 13, and the installation is completed. In addition, the disassembly process of the pressing portion 2 is opposite to the installation process, in the disassembly process, the movable clamping structure 243 is separated from the first clamping position 13, and then the pressing portion 2 is rotated upwards based on the inserting structure 241, so that the clamping rotating structure 244 can be separated from the second rotating shaft 14, at this time, the abutting structure 242 is also separated from the supporting and limiting structure 12, and the inserting structure 241 can be separated from the inserting position 11, so that the pressing portion 2 is disassembled.

The dismounting structure 16 may be a buckle, a screw, or other structure that can be operated to dismount the panel base 1 from the bottom shell 3.

in another exemplary embodiment, as shown in fig. 19, the dismounting structure 16 includes a connection screw 162, the left end of the panel base 1 is fastened to the bottom shell 3, and the right end is provided with a threaded connection hole adapted to the connection screw 162; the bottom shell 3 is provided with a counter bore matched with the threaded connection hole, and the connection screw 162 passes through the counter bore to be connected with the threaded connection hole so as to realize the detachable connection of the panel base body 1 and the bottom shell 3; wherein, the counter bore set up in the laminating of drain pan 3 is in the one side of wall, just the counter bore can hold the nut of connecting screw 162, when intelligence switch 100 installs in the wall, connecting screw 162 is hidden in between panel base member 1 and the wall.

The existing intelligent switch is generally fixedly connected with the heavy-current circuit board on the bottom shell, and the bottom shell is easy to deform towards the inside of the wall when being installed on the wall, so that the heavy-current circuit board moves towards the inside of the wall. The strong current circuit and the weak current circuit of the invention are concentrated on the same circuit board 5, and further the detection piece 52 is also arranged on the circuit board 5, if the circuit board 5 moves towards the inside of the wall, the gap between the key 21 and the detection piece 52 will become large, the condition that the key 21 cannot trigger the detection piece 52 can occur, and the circuit board 5 is easy to be damaged when the bottom shell 3 deforms greatly. To solve this problem, according to the embodiment of the present invention, as shown in fig. 18 and 15, the number of the circuit boards 5 is at least one, and each circuit board 5 is fixedly connected to the panel base 1, so that when the bottom case 3 is deformed greatly, the circuit boards 5 are not directly affected, and damage to the circuit boards 5 is avoided; the opposite sides of the bottom shell 3 are provided with mounting holes 31 for mounting outside, and the two sides of the bottom shell 3, which are not provided with the mounting holes 31, are connected with the panel base body 1, so that when the bottom shell 3 deforms in the mounting process, deformation amounts of the panel base body 1 and the circuit board 5 following the deformation of the bottom shell 3 are reduced, and therefore, the detection piece 52 can be accurately triggered even when the bottom shell 3 deforms by the key 21.

For this reason, according to an embodiment of the present invention, as shown in fig. 14, 11 and 12, the panel base 1 is provided with a circuit board 5 on a side facing away from the pressing portion 2, the display 101 is provided between the panel base 1 and the circuit board 5, and the display 101 is electrically connected to the circuit board 5; the display screen 101 has a third surface 1011 facing away from the circuit board 5, and the side surface of the display screen 101 and the third surface 1011 respectively abut against the panel base 1, so that the display screen 101 is limited by the panel base 1; the third surface 1011 is provided with a display area 1012, a display through hole 191 is formed in a position opposite to the display area 1012 of the panel substrate 1, a transparent cover plate 4 is covered on one side of the panel substrate 1 facing away from the circuit board 5, the transparent cover plate 4 covers the display through hole 191, and contents displayed in the display area 1012 are displayed outwards through the display through hole 191 and the transparent cover plate 4. The display screen 101 of the embodiment of the invention is arranged in the panel base body 1 from one side of the panel base body 1, which is far away from the transparent cover plate 4, and is limited between the panel base body 1 and the circuit board 5, when the display screen 101 is disassembled, each display screen 101 can be disassembled independently only by disassembling the circuit board 5, and the assembly state of other display screens 101 is not influenced by the display screen 101 in the disassembly process, so that the display screen 101 is more suitable for the structures of a plurality of display screens 101 of the embodiment of the invention; and the transparent cover plate 4 is not required to be disassembled in the disassembling process, so that the disassembling difficulty is reduced.

The display 101 abutting against the panel base 1 may be understood as the display 101 abutting against the panel base 1 directly or indirectly through other structures against the panel base 1. In an embodiment, as shown in fig. 14, a first double sided adhesive (not shown) is disposed between the display screen 101 and the panel substrate 1, and the display screen 101 is adhered to the panel substrate 1 by the first double sided adhesive, and the first double sided adhesive covers the periphery of the third surface 1011, so that the third surface 1011 is in sealing connection with the lower side of the display through hole 191. In addition, as shown in fig. 20, the transparent cover plate 4 is adhered to the upper side of the display through hole 191 through the back adhesive 41, so that the upper side and the lower side of the display through hole 191 are respectively sealed by the transparent cover plate 4 and the display screen 101, thereby avoiding dust and water vapor from entering between the transparent cover plate 4 and the display screen 101 and affecting the display effect.

Further, as shown in fig. 12, the panel base 1 is provided with abutment rib positions 192 around the side surface of the display screen 101, and the abutment rib positions 192 abut against the side surface of the display screen 101 to limit the side surface of the display screen 101.

Further, as shown in fig. 11, the circuit board 5 is fixedly connected to the panel base 1 by a plurality of fixing screws 554, so as to facilitate the disassembly and assembly of the circuit board 5 and thus the disassembly and assembly of the display screen 101. The display 101 is connected to the circuit board 5 through a flat cable 1013 so as to disconnect the display 101 from the circuit board 5 when the circuit board 5 is detached. Thereby improving the efficiency of replacing the display screen 101.

According to an embodiment of the present invention, as shown in fig. 14, the circuit board 5 is provided with a flat cable connection terminal 57, the display screen 101 is provided with a flat cable 1013 toward the third direction, the third direction is a direction in which the pressing end 23 of the pressing portion 2 faces the connection end 22, and the third direction is marked in fig. 14 after the flat cable 1013 is bent and inserted into the flat cable connection terminal 57. In the embodiment of the invention, the flat cable 1013 of the display screen 101 is arranged in the direction away from the key 21, so that the distance between the display screen 101 and the key 21 is closer, and the indication effect is better; and the flat cable 1013 and the pressing part 2 are prevented from being stacked in the thickness direction, and the flat cable 1013 is prevented from being damaged due to the fact that the pressing part 2 moves to drive the flat cable 1013 to move while the thickness of the intelligent switch 100 is thinned.

Further, as shown in fig. 14 and 11, a supporting foam 59 is disposed between the display screen 101 and the circuit board 5, and the supporting foam 59 provides a supporting force for the display screen 101. The upper end of the supporting foam 59 is abutted against and stuck to the display screen 101, the lower end is abutted against the circuit board 5, and the supporting foam 59 is in a compressed state, so that a supporting force is provided for the display screen 101, and the display screen 101 is connected with the panel base body 1 more stably. Wherein the flat cable connection terminal 57 is disposed below the supporting foam 59 and covered by the supporting foam 59, so that the flat cable 1013 is more stably connected with the flat cable connection terminal 57.

According to an embodiment of the present invention, as shown in fig. 20 and 5, a side of the transparent cover plate 4 facing the panel base 1 is provided with a light shielding layer 42; the light shielding layer 42 is provided with a display window 421 at a position opposite to the display area 1012, and the content displayed in the display area 1012 is displayed outwards through the display window 421; the light shielding layer 42 is specifically a black coating, and is printed on the back surface of the transparent cover plate 4 by a silk-screen printing method. The light shielding layer 42 serves to cover the internal structure and enhance the aesthetic appearance. Since the circuit board 5 is equipped with a strong current circuit and a weak current circuit, the display screen 101 is regarded as a charged body, and the creepage distance between the display screen 101 and the outer surface of the switch needs to be greater than 2mm to avoid electric shock to the user, for this purpose, as shown in fig. 14, a preset gap is provided between the transparent cover plate 4 and the display screen 101, so that the creepage distance between the display screen 101 and the upper surface of the transparent cover plate 4 is increased. In an embodiment, the preset gap is 1.2mm, and the thickness of the transparent cover plate 4 is 2mm.

However, due to the existence of the preset gap, when the smart switch 100 is mounted on the wall, a part of the upper end of the display area 1012 is blocked by the light shielding layer 42 (as shown in fig. 21, since the smart switch 100 is mounted on the wall at a position generally lower than the human eye, the viewing angle of the human eye looking at the display screen 101 is a downward inclined viewing angle, which results in that the upper edge of the display window 421 blocks a part of the display area 1012). For this reason, one end of the display area 1012 facing the fourth direction is provided with a blank area (not shown in fig. 21) in which no content is displayed so as to avoid the display content from being blocked by the light blocking layer 42; wherein the fourth direction is the same direction as the vertical upward direction when the smart switch 100 is mounted on a wall, in this embodiment, the fourth direction is the same direction as the third direction, and the fourth direction is shown in fig. 21. The blank area is set as the upper lateral area of the display area 1012 (i.e., the non-display area in fig. 37). Further, as shown in fig. 21, the display window 421 is disposed opposite to the display area 1012, and the size of the display window 421 is slightly larger than the size of the display area 1012, so as to reduce the shielding amount of the display window 421 to the display area 1012.

According to an embodiment of the present invention, as shown in fig. 6, the transparent cover 4 is disposed in parallel with the connection end 22 of the pressing portion 2, and a surface of the transparent cover 4 facing the fifth direction is flush with a surface of the pressing portion 2 facing the fifth direction. In an embodiment, when the pressing portion 2 is not pressed, the transparent cover plate 4 and the pressing portion 2 are both in a horizontal state in fig. 6.

According to an embodiment of the present invention, as shown in fig. 11 and 20, the circuit board 5 is provided with an infrared detection device 20, and the infrared detection device 20 includes: an infrared emission unit 201 for emitting a detection wave; an infrared receiving unit 202 is configured to trigger the display screen 101 when the detection wave is received. Wherein, the infrared detection device 20 is used for detecting the distance between the external object and the intelligent switch 100, and when the distance is close enough, the display screen 101 is triggered. Specifically, the detected wave emitted by the infrared emitting unit 201 is reflected by an external object and then transmitted to the infrared receiving unit 202, the closer the distance between the external object and the infrared receiving unit 202 is, the stronger the intensity of the reflected detected wave detected by the infrared receiving unit 202 is, when the intensity of the detected wave detected by the infrared receiving unit 202 is greater than a threshold value, the intelligent switch 100 determines that the distance between the external object and the intelligent switch 100 is smaller than a predetermined distance, and then the display screen 101 is controlled to be turned on. Wherein the detection wave may be an infrared light wave or other electromagnetic waves. Further, the transparent cover 4 covers the infrared emitting unit 201 and the infrared receiving unit 202, and the detection wave passes through the transparent cover 4 to be detected.

The inventor finds that the detection wave sent by the infrared emission unit 201 is easily transmitted to the infrared unit from the inside of the intelligent switch 100 through two error ways, so that the infrared detection device 20 misjudges, and one is that the detection wave is transmitted to the infrared receiving unit 202 through total internal reflection of the transparent cover plate 4; the other is that the detection wave is transmitted to the infrared receiving unit 202 through the gap between the panel base 1 and the circuit board 5, or when the panel base 1 is thin and light in color, the detection wave is transmitted directly to the infrared receiving unit 202 through the panel base 1. To attenuate these two erroneous routes of delivery, the present invention employs the following scheme: as shown in fig. 20, 11 and 6, the infrared emitting unit 201 includes an infrared light emitting tube 2012, and the infrared receiving unit 202 includes an infrared receiving head 2021; at least one display screen 101 is disposed between the infrared light emitting tube 2012 and the infrared receiving head 2021, so that the distance between the infrared receiving head 2021 and the infrared light emitting tube 2012 is increased, thereby weakening the total reflection of the detection wave inside the transparent cover plate 4; the shielding member 58 is disposed around the periphery of the infrared light emitting tube 2012, and the shielding member 58 blocks the detection wave on the side surface of the infrared light emitting tube 2012, so that the transmission of the detection wave to the infrared receiving unit 202 through the gap between the panel substrate 1 and the circuit board 5 or through the panel substrate 1 is reduced. By the two schemes, the transmission of detection waves inside the intelligent switch 100 is weakened, and misjudgment of the infrared detection device 20 is avoided.

It should be noted that, increasing the distance between the infrared receiving head 2021 and the infrared light emitting tube 2012 can prevent small objects such as flies and mosquitoes from triggering the infrared detecting device 20 by mistake to a certain extent, specifically, when the flies and mosquitoes rest on the switch surface, the body can only cover one of the infrared light emitting tube 2012 or the infrared receiving head 2021 due to the small volume of the flies and mosquitoes, which is insufficient for triggering the infrared detecting device 20.

In an embodiment, as shown in fig. 20, the number of the display screens 101 is three, the three display screens 101 are arranged at intervals along the first direction, the infrared light emitting tubes 2012 are disposed between the left display screen 101 and the middle display screen 101, and the infrared receiving head 2021 is disposed between the middle display screen 101 and the right display screen 101.

Further, as shown in fig. 6, 11 and 20, the shielding member 58 is a black ring-shaped foam, the ring-shaped foam surrounds the infrared light emitting tube 2012, the upper end of the ring-shaped foam abuts against the back glue 41 of the transparent cover plate 4, and the lower end abuts against the circuit board 5, so as to block the detection wave from passing through the ring-shaped foam from the side. It is noted that, since the annular foam is made of a flexible material, the annular foam can be tightly attached to the circuit board 5, so that the detection waves are prevented from being transmitted from the gap between the annular foam and the circuit board 5. Further, the panel substrate 1 is provided with a transmitting through hole 193 and a receiving through hole 194 at corresponding positions of the annular foam and the infrared receiving head 2021, the transmitting through hole 193 accommodates the annular foam and limits the annular foam, and the receiving through hole 194 accommodates the infrared receiving head 2021.

Further, as shown in fig. 20 and fig. 5, the light shielding layer 42 is provided with an emission window 422 at a position opposite to the infrared light emitting tube 2012, the light shielding layer 42 is provided with a receiving window 423 at a position opposite to the infrared receiving head 2021, and the infrared receiving head 2021 receives an external detection wave through the receiving window 423; the infrared light emitting tube 2012 emits the detection wave to the outside through the emission window 422, and the emission angle of the detection wave is limited to be less than 90 ° by the emission window 422. When the distance between the infrared light emitting tube 2012 and the light shielding layer 42 is fixed, the smaller the size of the emission window 422, the smaller the detection wave emission angle, the smaller the detection angle of the infrared detection device 20; when the size of the emission window 422 is constant, the larger the distance between the infrared light emitting tube 2012 and the transparent cover plate 4 is, the smaller the detection wave emission angle is, and the smaller the detection angle of the infrared detection device 20 is. The detection angle of the infrared detection device 20 can be accurately controlled by controlling the size of the emission window 422 and the distance between the infrared light emitting tube 2012 and the transparent cover plate 4. The embodiment of the present invention controls the detection angle of the infrared detection device 20 to be less than 90 ° because the infrared detection device 20 is easily triggered by mistake when the detection angle is too large. When the detection angle is too small, the user is close to the intelligent switch 100 from the side, so that the inventor is verified by experiments to control the detection angle to be 30-60 degrees to reach a proper trigger range.

Further, as shown in fig. 20, the back glue 41 of the transparent cover plate 4 is provided with a first back glue hole 411, a second back glue hole 412 and a third back glue hole 413 at opposite positions of the display window 421, the emission window 422 and the receiving window 423, and the sizes of the first back glue hole 411, the second back glue hole 412 and the third back glue hole 413 are respectively larger than the sizes of the display window 421, the emission window 422 and the receiving window 423.

Compared with a spring, the foam has the characteristic of slow rebound, and the adoption of the foam to provide the reset force can enable the pressing hand feeling of the key 21 to have damping sense, so that the pressing hand feeling is more advanced. Further, a foam mounting position 291 is provided on the lower surface of the key 21, and the reset foam 29 is adhered to the foam mounting position 291. Further, in the first direction, reinforcing rib positions are provided on both sides of each key 21 for reinforcing rigidity of the key 21.

Further, as shown in fig. 22, a thinned inclined surface 261 is disposed on one side of each key 21 adjacent to other keys 21, and the thinned inclined surface 261 is used for thinning the edge of the key 21, so that the thickness of the key 21 near the connection structure 25 is thinned, and thus the linkage effect between the keys 21 is reduced, that is, the movement of one key 21 does not drive the movement of the adjacent other keys 21. In addition, the width of the injection mold at the position of the thinned inclined surface 261 can be increased by setting the thinned inclined surface 261 on the key 21, so that the corresponding injection mold at the position is not easy to damage, and particularly, if the thinned inclined surface 261 is not set on the key 21, the injection mold at the position corresponding to the dividing slit 26 is in a slender strip shape and is easy to damage, the thinned inclined surface 261 enables the thickness of the key 21 at the position corresponding to the dividing slit 26 to be thinned, and the corresponding injection mold at the position is widened, so that the strength of the injection mold is increased.

The display screen 101, the infrared light emitting tube 2012, and the infrared receiving head 2021 are juxtaposed in the first direction.

The infrared light emitting tube 2012 is disposed on the left side of the display screen 101, and the infrared receiving head 2021 is disposed on the right side of the display screen 101, so that the distance between the infrared light emitting tube 2012 and the infrared receiving head 2021 is increased, thereby weakening the total internal reflection of the detection wave on the transparent cover plate 4 and avoiding erroneous judgment of the infrared detecting device 20. The display screen 101, the infrared light emitting tube 2012, and the infrared receiving head 2021 are juxtaposed in the first direction. The panel substrate 1 is provided with the display through hole 191, the transmitting through hole 193 and the receiving through hole 194 at the corresponding positions of the display area 1012, the infrared light emitting tube 2012 and the infrared receiving head 2021 of the display screen 101.

Further, as shown in fig. 20 and fig. 6, the intelligent switch 100 further includes a transparent cover plate 4, which is covered on the panel base 1, and each display screen 101 is covered by the transparent cover plate 4, and the display screen 101 displays contents from outside through the transparent cover plate 4; the transparent cover plates 4 are arranged at the end parts of the keys 21, and one surface of each transparent cover plate 4 facing away from the second direction is flush with one surface of each key 21 facing away from the second direction; wherein the second direction is the same as the direction in which the key 21 is pressed. The technical details of the transparent cover plate 4 are described in detail above, and are not described herein.

According to an embodiment of the present invention, as shown in fig. 11, 12 and 14, the intelligent switch 100 includes a display screen 101, the display screen 101 is disposed on the panel substrate 1 and electrically connected to the circuit board 5, and the display screen 101 is used for displaying key information of the keys 21; the display screen 101 is disposed between the panel substrate 1 and the circuit board 5, the display screen 101 has a third surface 1011 facing away from the circuit board 5, and the side surface of the display screen 101 and the third surface 1011 respectively abut against the panel substrate 1, so that the display screen 101 is limited by the panel substrate 1; a supporting foam 59 is arranged between the display screen 101 and the circuit board 5, and the supporting foam 59 provides supporting force for the display screen 101. The technical details of the display 101, the panel substrate 1 and the supporting foam 59 are described in detail above, and will not be described herein.

Further, as shown in fig. 14, a first double-sided adhesive (not shown) is disposed between the display screen 101 and the panel substrate 1, and the display screen 101 is adhered to the panel substrate 1 by the first double-sided adhesive, and the first double-sided adhesive covers the periphery of the third surface 1011, so that the third surface 1011 is connected with the lower side of the display through hole 191 in a sealing manner. In addition, as shown in fig. 20, the transparent cover plate 4 is adhered to the upper side of the display through hole 191 through the back adhesive 41, so that the upper side and the lower side of the display through hole 191 are respectively sealed by the transparent cover plate 4 and the display screen 101, thereby avoiding dust and water vapor from entering between the transparent cover plate 4 and the display screen 101 and affecting the display effect. The technical details of the first double-sided tape are described in detail above, and are not described herein.

In addition, the current intelligent wall switch generally has at least one circuit board fixed connection in the drain pan, when the drain pan is installing in the wall, because installation screw screws up and leads to the drain pan to take place deformation towards the wall inside easily, the circuit board will follow the drain pan and take place deformation, probably causes the circuit board to damage when drain pan deflection is too big. Based on the above, the invention also provides an intelligent switch to solve the above problems. The drawings in this embodiment will be shared with those of the above embodiments.

As shown in fig. 18 and 15, the intelligent switch 100 includes a bottom case 3, a panel base 1, and at least one circuit board 5, where the panel base 1 is covered on the bottom case 3; each circuit board 5 is fixedly connected to the panel base 1, mounting holes 31 for mounting outside are formed in two opposite sides of the bottom shell 3, and two sides of the bottom shell 3, which are not provided with the mounting holes 31, are connected to the panel base 1, so that deformation amounts of the panel base 1 and the circuit board 5 following deformation of the bottom shell 3 are reduced when the bottom shell 3 deforms in a mounting process. The technical details of the bottom case 3, the panel base 1 and the circuit board 5 are described in detail above, and will not be described here again. Fig. 18 is a simplified cross-sectional view of the smart switch 100. Fig. 18 includes two diagrams, a first diagram is a schematic structural diagram before deformation of the bottom shell 3, and a second diagram is a schematic structural diagram after deformation of the bottom shell 3, and as can be seen from the diagrams, when the bottom shell 3 deforms toward the inside of the wall, since the left and right ends of the panel base 1 are connected to the bottom shell 3, and the mounting screws 32 are disposed on two sides of the bottom shell 3, which are not connected to the panel base 1, deformation of the bottom shell 3 caused by the mounting screws 32 affects less the panel base 1, and the left and right ends of the bottom shell 3 abut against the wall, so that the influence of deformation of the bottom shell 3 on the panel base 1 is further reduced. Because each circuit board 5 is connected to the panel base 1 and not directly connected to the bottom shell 3, the deformation of the bottom shell 3 has very little influence on the circuit board 5, thereby avoiding the damage of the circuit board 5.

Further, the number of the circuit boards 5 is one, the circuit boards 5 are connected with external wires and are provided with a strong current circuit and a weak current circuit, and the circuit boards 5 are provided with a relay 40, a power supply circuit 50 and a detecting element 52; the power supply circuit 50 is electrically connected to the external wire and is used for converting alternating current into direct current; the detecting member 52 is configured to detect manipulation, and the relay 40 is electrically connected to the detecting member 52, and is capable of switching an on-off state in response to the detecting member 52 being manipulated. Wherein the manipulation may be a pressing manipulation or a touch manipulation, and when the manipulation is a pressing manipulation, the detecting member 52 may be a detecting switch, a tact switch, a micro switch, a membrane switch, a hall, or the like, which can be triggered in response to the pressing manipulation; when the manipulation is a touch manipulation, the detecting member 52 may be a capacitive touch sensing module or the like, which can be triggered in response to the touch manipulation. The technical details of the detecting member 52, the relay 40, and the power supply circuit 50 are described in detail above, and will not be described here again. The invention concentrates the strong current circuit and the weak current circuit on the same circuit board 5, which can save the space of the bottom shell 3, and the volume of the bottom shell 3 is smaller, so that the bottom shell 3 can be more conveniently placed in the cassette, and the installation convenience of the intelligent switch 100 is improved; at the same time, more space is left in the cassette to accommodate other structures, such as wiring harnesses and the like.

The existing intelligent switch is generally fixedly connected with the heavy-current circuit board on the bottom shell, and the bottom shell is easy to deform towards the inside of the wall when being installed on the wall, so that the heavy-current circuit board moves towards the inside of the wall. The strong current circuit and the weak current circuit are concentrated on the same circuit board, and the detection piece is further arranged on the circuit board, so that if the circuit board moves towards the inside of the wall, the gap between the key and the detection piece is increased, and the condition that the key cannot trigger the detection piece can occur. To solve this problem, according to an embodiment of the present invention, as shown in fig. 6 and 9, the smart switch 100 further includes a key 21 abutting against the detecting element 52 for receiving a pressing manipulation and triggering the detecting element 52 in response to the pressing manipulation; the key 21 is connected to the panel base 1, so that when the bottom case 3 is deformed, the relative positional relationship between the circuit board 5 and the key 21 is not greatly affected, and the key 21 can trigger the detecting element 52 when the bottom case 3 is deformed. The connection structure 25 between the key 21 and the panel substrate 1 is described in detail above, and will not be described here again. The sensing member 52 is preferably a tact switch.

According to an embodiment of the present invention, the bottom case 3 does not provide a direct fixing constraint to the circuit board 5, so as to further reduce the influence of deformation of the bottom case 3 on the circuit board 5.

According to the embodiment of the invention, as shown in fig. 13 and 9, the panel base 1 is detachably connected with the bottom shell 3, so that when the panel base 1 is detached from the bottom shell 3, each circuit board 5 is detached from the bottom shell 3 along with the panel base 1, and in the assembly process, the bottom shell 3 can be quickly and conveniently buckled with the panel base 1 by fixing the circuit board 5 on the panel base 1, so that the assembly efficiency is improved. Further, the panel base 1 and the bottom shell 3 form a containing cavity, the circuit board 5 is contained in the containing cavity, and the circuit board 5 is loaded with a strong current circuit and a weak current circuit; the panel base 1 includes a dismounting structure 16 for dismounting the panel base 1 from the bottom case 3, the dismounting structure 16 is disposed on the back surface of the panel base 1, so that the dismounting structure 16 is hidden between the panel base 1 and the wall when the intelligent switch 100 is mounted on the wall. Since the strong current circuit and the weak current circuit are arranged on the same circuit board 5, the circuit board 5 cannot be exposed to prevent electric shock. For this purpose, the circuit board 5 of the present invention is accommodated between the panel base 1 and the bottom case 3, and the panel base 1 does not need to be detached when the intelligent switch 100 is mounted. Since the disassembly structure 16 is hidden between the panel base 1 and the wall, the user cannot disassemble the panel base 1, so that the risk of electric shock caused by exposure of the circuit board 5 due to incorrect disassembly of the panel base 1 by the user is avoided. The technical details of the panel base 1, the bottom case 3 and the disassembling structure 16 are described in detail above, and are not described here again.

According to an embodiment of the present invention, as shown in fig. 15 and 18, the circuit board 5 is fixedly connected to the panel base 1 through a plurality of fixing screws 554, the bottom shell 3 is provided with a recess 35 at a position corresponding to the fixing screws 554, and the recess 35 is used for accommodating a nut of the fixing screw 554, so that the circuit board 5 can be close to the bottom shell 3, thereby reducing the thickness of the panel base. The technical details of the avoiding recess 35 are described in detail above, and will not be described herein.

Since the circuit board 5 of the present invention carries a strong current circuit, there is a certain probability that the strong current on the circuit board 5 will be transferred to the mounting screw 32 along the surface of the insulating material, and therefore, a sufficient creepage distance should be designed to avoid leakage of the current on the circuit board 5 to the mounting screw 32. The creepage distance is the shortest spatial distance between two conductive parts measured along the surface of the insulating material. According to an embodiment of the present invention, as shown in fig. 15 and 13, the mounting hole 31 is used for inserting a mounting screw 32, and the bottom case 3 is mounted to the outside by the mounting screw 32; the bottom shell 3 is provided with a partition wall 36 protruding towards the panel substrate 1 around the mounting hole 31, the circuit board 5 is arranged outside the partition wall 36, the partition wall 36 surrounds the mounting hole 31, and current on the circuit board 5 can reach the mounting screw 32 only by crossing the partition wall 36, so that the creepage distance between the circuit board 5 and the mounting screw 32 is increased, and the electric shock of a user touching the mounting screw 32 is avoided.

With the development of the internet of things, the functions of the intelligent switch 100 are more and more diversified, even the functions of the intelligent switch 100 may change, so that the conventional intelligent switch 100 capable of fixing the functions of each key cannot meet the needs of the user gradually, and with the diversification of the functions of the intelligent switch 100, the functions of each key may also change according to the needs of the user, based on which, please refer to fig. 25, a schematic diagram of the intelligent switch 100 provided by the embodiment of the present invention is provided, and it can be seen that the intelligent switch 100 at least includes the display device 10, the processing device 30 and the infrared detection device 20. The processing device 30 detects the outside through the infrared detection device 20, and controls the display device 10 according to the detection result, wherein the content displayed on the display device 10 can be customized according to the user's requirement. The external detection may be understood as detecting whether a person approaches in a specified detection area based on the smart switch 100.

It can be understood that the intelligent switch 100 such as a wall-type key switch, a touch screen switch, a touch switch and the like is generally disposed at a position where a human hand is easy to touch, so that the use environment of the intelligent switch 100 is relatively complex, and since the infrared detection technology is based on active emission and reception of detection waves in an infrared band to realize external detection, any object capable of reflecting the detection waves is likely to trigger detection to be approaching, so that the infrared detection technology is generally considered to be unsuitable for a complex use scene of the intelligent switch 100 in the industry, so that the infrared detection technology is not applied to the intelligent switch 100 such as a wall-type key switch, a touch screen switch, a touch switch and the like until now, but instead of other proximity sensing technologies with strong anti-interference performance such as infrared pyroelectric and microwave radar, the infrared pyroelectric needs to be configured with a chenille lens to affect the overall appearance and structure of the intelligent switch 100, and the microwave radar has high cost, and for some low-cost intelligent switches 100, the manufacturing cost cannot be controlled to affect the large-scale market application.

Based on this, the present embodiment provides an intelligent switch 100, which uses an infrared detection technology to perform proximity sensing, and the distance of the proximity sensing can be freely defined by a user to improve the interference caused by the complexity of the intelligent switch 100. The intelligent switch 100 provided in this embodiment focuses on the description of hardware and software, and the corresponding structural scheme is applicable to the intelligent switch 100 described in any of the embodiments shown in fig. 1 to 24. Further, the embodiment corresponding to the software and/or hardware scheme of the intelligent switch 100 provided in this embodiment can be combined with the configuration scheme of the intelligent switch 100 described in any of the embodiments described above with reference to fig. 1 to 24.

Specifically, the display device 10 has at least two operating states;

the infrared detection device 20 is configured to emit detection waves outwards to form a designated detection area, and includes a plurality of driving circuits 2011 for driving the detection waves to be emitted outwards, where the driving circuits are available for gating; the driving resistances of the driving circuits 2011 are different (as shown in fig. 26), so that the range of the designated detection area corresponding to each driving circuit 2011 is different;

the processing device 30 is connected to the display device 10 and the infrared detection device 20, respectively, and is configured to obtain a detection result of the infrared detection device 20, and switch the operating state of the display device 10 according to the detection result, where the processing device 30 can change the gated driving circuit 2011.

The operation state of the display device 10 may be understood as the display device 10 turning on a screen, turning off a screen, and the like. Further, at least two operation states of the display device 10 are different from each other, and include at least a lit state (on-screen state) and an extinguished state (off-screen state). The range of the specified detection area can be understood as a range in which the detection waves can reach and be reflected, and the processing device 30 gates one path of the driving circuit 2011 at most at any time, so that the range of the specified detection area is specified alternatively.

In a specific example, the processing device 30 detects, by the infrared detection device 20, a current state of the intelligent switch 100, the current state being indicative of whether a person approaches a designated detection area of the intelligent switch 100, and the display device 10 is configured to be controllable by the processing device 30 to switch to an on state or an off state; the multi-path driving circuit 2011 is connected to the same power supply, the driving resistor is used for limiting the driving capability of the gated driving circuit 2011, and under the condition that the power supply is fixed, the larger the driving resistor is, the smaller the current of the corresponding driving circuit 2011 is, namely the weaker the driving capability is, and the closer the detection distance is; the smaller the driving resistance, the larger the current of the corresponding driving circuit 2011, i.e., the stronger the driving capability, the further the detection distance. It should be understood that the infrared detection device 20 is configured to detect the detected wave based on the infrared band, so any object capable of reflecting the detected wave may trigger the infrared detection device 20, and thus the "person" in the "person-in-person" described in this embodiment should be understood in a broad sense, that is, any person, animal, and other object capable of reflecting the detected wave and triggering the infrared detection device 20.

Furthermore, based on the above-mentioned scheme, the intelligent switch 100 provided in this embodiment overcomes the technical prejudice that the infrared detection technology generally considered in the industry is not suitable for being applied to the application scenario of the intelligent switch 100, and adopts the low-cost infrared detection device 20 to perform proximity sensing detection, and simultaneously drives the infrared detection device 20 alternatively through the driving circuit 2011 with different multiplexing resistors, so that the detection distance can be changed along with the change of the gated driving circuit 2011, so that the intelligent switch 100 has the capability of adjusting the detection distance, and the user can adjust the detection distance according to the actual application environment of the intelligent switch 100, so as to improve the interference problem.

Further, in order to distinguish the detection distances corresponding to the two driving circuits 2011 as much as possible, the difference of the resistance values of the driving resistors between any two driving circuits 2011 is greater than 10Ω, so that when any two driving circuits 2011 are switched, the change of the detection distances can be obviously distinguished. In practical tests, when the resistance difference of the driving resistors of the two driving circuits 2011 is set to 10Ω, the detection distance can at least make the detection distance of some types of infrared light emitting tubes 2012 have a difference of 5 cm.

Further, in order to facilitate the user to freely set the proximity sensing distance of the intelligent switch 100, the processing device 30 is further configured to receive an external selection signal, where the selection signal is used to switch the gated driving circuit 2011.

Specifically, the user may send the selection signal through the intelligent terminal, for example, after the user joins in marriage the intelligent switch 100, a communication relationship is established between the mobile phone and the intelligent switch 100, and then the detection distance is adjusted through an operation interface of an application program (app) installed on the mobile phone and corresponding to the intelligent switch 100 (as shown in fig. 27), and then the application program directly or indirectly sends the corresponding selection signal to the intelligent switch 100, so as to adjust the detection distance.

In combination with the scheme that the resistance difference of the driving resistor between any two paths of driving circuits 2011 is greater than 10Ω in the above embodiment, when the user switches the driving circuits 2011 of the intelligent switch 100 based on the intelligent terminal, an obvious gear difference of the detection distance can be formed, so that each time one driving circuit 2011 is switched, the change of the detection distance can be intuitively felt by the user, and the user can conveniently adjust the detection distance according to the actual requirement.

Further, the selection signals include a first selection signal, a second selection signal, and a third selection signal; wherein the processing device 30 is capable of turning off the infrared detection device 20 according to a first selection signal, the processing device 30 is capable of gating the first driving circuit 20111 in the multiplexing driving circuit 2011 according to a second selection signal, and the processing device 30 is capable of gating the second driving circuit 20112 in the multiplexing driving circuit 2011 according to a third selection signal.

The first selection signal is generated after a first gear among a plurality of preset distance gears on the intelligent terminal is selected, the second selection signal is generated after a second gear among the plurality of gears is selected, and the third selection signal is generated after a third gear among the plurality of gears is selected (as shown in fig. 27).

Furthermore, the first gear, the second gear and the third gear respectively form three gears for adjusting the detection distance of the intelligent switch 100, wherein the infrared detection device 20 is turned off under the first gear, that is, the detection distance of the intelligent switch 100 is 0, the second gear and the third gear respectively represent two different detection distances, and the user can conveniently switch the first gear to the third gear through the intelligent terminal so as to freely select the detection distance of the intelligent switch 100.

Further, the difference between the resistance values of the driving resistor of the first driving circuit 20111 and the driving resistor of the second driving circuit 20112 is greater than or equal to 50Ω, so that there is at least a 20cm difference between the second gear and the third gear.

In a specific example, as shown in fig. 28, a driving resistor of 47 Ω is connected in series to the first driving circuit 20111, and a driving resistor of 100 Ω is connected in series to the second driving circuit 2011, so that a detection distance a is provided when the first driving circuit 20111 is gated, and a detection distance B is provided when the second driving circuit 20112 is gated. Wherein the value range of A is 80 cm-100 cm, and the value range of B is 30 cm-50 cm. In this example, the difference between the driving resistance of the first driving circuit 20111 and the driving resistance of the second driving circuit 20112 is 53 Ω, so that a distance difference of 50cm or more can be formed between the second gear and the third gear.

It should be noted that, the detection distance of 80cm to 100cm may be understood as a detection distance formed by a certain point value or a certain section within a range of 80cm to 100cm, for example, when the detection distance is 80cm, the designated detection area formed by the intelligent switch 100 in the second gear will cover a detection distance of 0cm to 80cm, and when a person is about 80cm from the front surface of the intelligent switch 100, the display device will be triggered to light the screen. When the detection distance is 80cm to 90cm, the specified detection area formed by the intelligent switch 100 in the second gear will cover the detection distance of nearest 0cm and farthest [80cm,90cm ], and the farthest detection distance in the second gear is fluctuated in a range and is not a fixed value. Similarly, it can be understood that the above 30cm to 50cm can trigger the display device to light the screen when the detected distance is about 30cm from the front of the intelligent switch 100.

In one possible use scenario, the intelligent switch 100 is installed at a hallway, it will be understood that the width of a hallway is generally about 100cm, the width of a hallway of a house with some small dwellings may be narrower, and the actual space of the hallway is narrower due to the fact that the hallway may be filled with articles, installed shoe cabinets, or clothes changing cabinets, etc. If the detection distance of the intelligent switch 100 is not controlled at this time, the object or the wall surface opposite to the intelligent switch 100 is likely to be directly reflected by the emitted detection wave, so that the infrared detection device 20 is always in a triggered state, and the proximity sensing fails. Under such a use scene, based on the scheme of this embodiment, the user can switch the proximity sensing of intelligent switch 100 to the third gear in order to shorten the furthest detection distance for the appointed detection area at this moment can not cover to the wall or article on intelligent switch 100 opposite side, and the distance of detection wave is limited, can't reach the wall of opposite side, but can reflect back the detection wave and trigger infrared detection device 20 when the human body passes through the vestibule again, and then effectively avoid the interference.

In another possible use scenario, the intelligent switch 100 is installed in a living room, and the surroundings thereof are clear, at this time, in order to improve the bright screen sensitivity of the intelligent switch 100, the user may set the intelligent switch 100 to the second gear, and further, the user may trigger the intelligent switch 100 at a remote location, so as to improve the user experience.

Under the above-mentioned two kinds of use scenes, the installation environment of intelligent switch 100 is different, leads to its required detection distance of approach response also different, and the scheme that this embodiment provided for intelligent switch 100 can freely switch to detection distance based on user's actual demand, has increased the suitability and the flexibility under the use scene that infrared detection technique was applied to intelligent switch 100 such product.

In some embodiments, as shown in fig. 29, the infrared detection device 20 includes an infrared emitting unit 201 and an infrared receiving unit 202, and the processing device 30 is configured to drive the gated driving circuit 2011 in the infrared emitting unit 201 by two different driving signals (for example, the encoded signal and the carrier signal in fig. 29) to synthesize the detected wave with a characteristic signal feature, so that the infrared receiving unit 202 recognizes the detected wave according to the characteristic signal feature.

Further, if the detected wave received by the infrared receiving unit 202 does not meet the characteristic signal characteristic, the detected wave will not respond, so as to filter the infrared wave in other coding modes, and prevent interference of the infrared wave emitted by the air conditioner remote control, television remote control and other devices.

The structural position of the infrared detection device 20 in the intelligent switch 100 can be understood by referring to the descriptions of the embodiments shown in fig. 11, fig. 6 and fig. 20 and the corresponding examples thereof.

Further, as shown in fig. 30, the infrared emission unit 201 includes:

the characteristic synthesis circuit 2013 is electrically connected with the processing device 30 and can be controlled by one path of driving signals of the processing device 30 to switch on-off states according to a preset rule;

an infrared light emitting tube 2012 is connected in series with the characteristic synthesizing circuit 2013 and each driving circuit 2011 to emit infrared light by being driven by the selected driving circuit 2011 when the characteristic synthesizing circuit 2013 is turned on.

Wherein the driving circuit 2011 is driven by another driving signal of the processing device 30, which may be, for example, a PWM signal of 38khz output by a PWM port as described in the following embodiments. Further, based on the one driving signal and the other driving signal, the characteristic synthesizing circuit 2023 and the driving circuit 2011 jointly drive the infrared light emitting tube 2012 to synthesize a detection wave having the characteristic signal characteristic.

Specifically, as shown in fig. 31, a specific implementation circuit is provided, and it can be seen that:

the driving circuit 2011 has two paths, which are respectively a first driving circuit 20111 formed by a triode Q11 and a second driving circuit 20112 formed by a triode Q7, wherein the driving resistance of the first driving circuit 20111 is R93 of 47 Ω, the driving resistance of the second driving circuit 20112 is R88 of 100 Ω, the characteristic synthesis circuit 2013 comprises an electronic switch formed by a MOS transistor Q8, the infrared light emitting diode LED1 is connected in series between Q8 and each driving circuit 2011, the electronic switch can be controlled by the processing device 30 to be turned on or turned off, the infrared light emitting diode LED1 is powered when the electronic switch is turned on, and the infrared light emitting diode 2012 is powered off when the electronic switch is turned off.

Specifically, the first driving circuit 20111 is composed of Q11, resistors R93, R91 and R92, wherein the collector of Q11 is electrically connected to the cathode of the LED1 through R93, the emitter of Q11 is grounded, the base of Q11 is electrically connected to the processing device 30 as a controlled terminal through R91 to be controlled by the processing device 30 to switch between on and off, R92 is electrically connected between the base and the emitter of Q11, and one end of the processing device 30 connected to R91 is further grounded through a voltage stabilizing tube D30 to form a voltage stabilizing protection function.

The second driving circuit 20112 is composed of Q7, resistors R88, R82 and R14, wherein the collector of Q7 is electrically connected to the cathode of the LED1 through R88, the emitter of Q7 is grounded, the base of Q7 is electrically connected to the processing device 30 as a controlled end through R82 to be controlled by the processing device 30 to switch on and off, R14 is electrically connected between the base and the emitter of Q7, and one end of the processing device 30 connected to R82 is further grounded through a voltage stabilizing tube D29 to form a voltage stabilizing protection function.

Q8 is a PMOS tube, the S pole of the PMOS tube is connected with the power supply (3.3V), the D pole is connected with the anode of the LED1, and the G pole is connected with the processing device 30 as a controlled end through the current limiting resistor R85 so as to be controlled by the processing device 30 to switch between on and off. In addition, the G pole of Q8 is also provided with a pull-up resistor R84, and the power supply is also provided with C15 for voltage stabilizing filtering.

When the driving resistance is 100Ω, the actual operating current is (3.3V-1.3V)/100deg.OMEGA=20mA. At this point the resistive loss was 0.04w and the emitted power of led1 was 1.3v×20ma=26 mW.

When the current limiting resistance is 47 omega, the actual working current is (3.3V-1.3V)/47 omega-42.6 mA. At this point the resistive loss was 0.08w and the led1 emitted power was 1.3v×42.6ma= 55.38mW.

As shown in FIG. 31, the infrared light emitting diode LED1 can be specifically a patch infrared LED with model XYC-IRA4335A65-X4 of Xin Yongcheng, which is a low-power-consumption diode packaged by 4335, and has the advantages of high emission power, uniform light receiving angle and the like, the emission wavelength is 940nm, the maximum continuous working current is 100mA, and the maximum power consumption is 150mW.

Further, the emission angle of the infrared light emitting tube LED1 is limited to: the X axis is [63 DEG, 73 DEG ] ], and the Y axis is [22 DEG, 28 DEG ] ]. In a specific example, for example, a patch infrared LED of model XYC-IRA4335a65-X4 is used, which has an emission angle of 66 degrees on the X axis, that is, 33 degrees each, and 25 degrees on the Y axis, with an off-center angle of at most +5 degrees for both the X axis and the Y axis, and at least-5 degrees.

Furthermore, the larger lateral emission angle (X-axis emission angle) makes the infrared light emitting tube suitable for use in a usage scenario of the intelligent switch 100 where a lateral detection range is required to be large.

Further, the driving signal includes a carrier signal and a code signal, wherein the processing device 30 gates a driving circuit 2011 through the carrier signal, and drives the feature synthesizing circuit 2013 to be turned on or off through the code signal, so as to synthesize the infrared light emitting tube 2012 to emit the detection wave with the characteristic signal feature.

In a specific example, as shown in fig. 31, the processing device 30 outputs PWM signals (ir_pwm 1 and ir_pwm 2) of 38khz as the carrier signal through a PWM port, and outputs a predetermined code sequence through a serial port to form a code signal (ir_tx) having the characteristic signal characteristic.

The operation of the circuit shown in fig. 31 can be understood as: when the first driving circuit 20111 is gated, the processing device 30 drives the on-off of the Q11 by outputting a PWM signal of 38khz through the ir_pwm1, and simultaneously drives the Q8 to regularly open and close according to a predetermined coding sequence by outputting a coding signal ir_tx through the serial port, so that the LED1 realizes infrared light coding output, and emits infrared detection waves conforming to the characteristic signal characteristics. Similarly, the second driving circuit 20112 can be understood as well when it is turned on.

Furthermore, in this embodiment, a scheme is provided for simulating the transmission of the detection wave through the serial port and the PWM interface, so that some processing apparatuses 30 (for example, the MHCB05P-B module of millet company in the subsequent embodiment) that do not support simultaneous transceiving can also be used. In other words, the processing device 30 generally adopts a single-chip microcomputer or a module, and some single-chip microcomputers do not support simultaneous receiving and transmitting of the infrared detection waves in order to reduce the volume and save the hardware cost, and the scheme provided by the embodiment enables the processing device 30 to simulate transmitting of the detection waves through a serial port and a PWM interface. Furthermore, only by feeding a predetermined code sequence into the serial port, the detection wave with the code can be simulated, so that the processing device 30 can realize infrared detection by simulating the detection wave of the infrared band and receiving the detection wave without supporting simultaneous transmission and reception. And the time sequence corresponding to the preset coding sequence is controlled through the serial port, compared with the time sequence controlled through software of the IO port, the method has better time sequence stability, so that the emitted detection wave is more stable, and the detection stability is ensured.

Further, as shown in fig. 32, the characteristic signal features are specifically defined as an identification area, a data area and a verification area, which are connected to each other, wherein the identification area is used for the infrared receiving unit 202 to identify whether the detection wave is valid, and the data area and the verification area are used for the infrared receiving unit 202 to identify whether the detection wave is legal.

In a specific example, bit 1 is defined as 500us high plus 1500us low, bit 0 is defined as 500us high plus 500us low, the identification area is defined as 5000us high plus 2500us low, the data area is 16 times alternating bit 1 and bit 0, and the verification area is 500us high plus untimely low. Then during operation: the infrared receiving unit 202 determines that the detection wave is valid when the received detection wave has a continuous high level of 5000us and a continuous low level of 2500us, and further considers the detection wave to be legal after receiving the waveform characteristics corresponding to the 16 alternately appearing bit 1 and bit 0 and the high level of 500us and the untimely low level successively, and further outputs a trigger signal to trigger the processing device 30.

The detection waves compiled based on the codes in the preset format shown in fig. 32 can filter some naturally generated disordered infrared waves through the identification area to improve the anti-interference capability, and can filter the infrared waves which are transmitted by the air conditioner remote control, television remote control and other equipment and are distributed according to a certain rule through the data area and verification, wherein the addition of the verification area can improve the safety, reduce the risk of being broken and improve the safety.

In some embodiments, the processing device 30 is further configured to control the infrared emission unit 201 of the infrared detection device 20 to operate in a periodically alternating emission state in which the infrared emission unit 201 emits the detection wave to the outside and a pause state in which the infrared emission unit 201 stops emitting the detection wave.

Furthermore, in this embodiment, in order to reduce the load of the processing device 30, the infrared emitting unit 201 of the infrared detecting device 20 is not in a continuous emitting state, but is alternately switched between an emitting state and a suspending state, and in the suspending state, the infrared emitting unit 201 of the infrared detecting device 20 is in a rest mode, and does not emit a detection wave to the outside, so as to reduce the load of the processing device 30.

Further, in order to ensure that the detectability of the infrared detection device 20 becomes stable before and after the display device 10 is turned on, in the present embodiment, the durations of the emission states are set to be the same before and after the display device 10 is turned on, and the difference in the durations of the pause states is less than or equal to 100ms.

Further, the present embodiment ensures the stability of the duration of the emission state of the infrared emission unit 201 and allows the duration of the suspension state of the infrared emission unit 201 to fluctuate within a certain range. In other words, if the duration of each emission state of the infrared emission unit 201 before the display device 10 is lit is defined as a first time, the duration of each emission state of the infrared emission unit 201 after the display device 10 is lit is defined as a second time, the first time and the second time are set to be the same in the present embodiment, if the duration of each suspension state of the infrared emission unit 201 before the display device 10 is lit is defined as a third time, the duration of each suspension state of the infrared emission unit 201 after the display device 10 is lit is defined as a fourth time, and the difference between the third time and the fourth time is set to be less than or equal to 100ms in the present embodiment. It has been experimentally demonstrated that the difference between the third time and the fourth time fluctuates in the range of 100ms without causing a large influence on the detection performance of the infrared detection device 20.

Further, the ratio of the duration of the emission state to the duty cycle is set to be greater than or equal to 10% before the display device 10 is lighted. The duty cycle is the sum of the duration of the transmitting state and the duration of the suspending state.

In one example, the duration of the emission state is set to be about 56ms and the time of the complete duty cycle of one emission state and pause time is set to be 100ms before the display device 10 is lighted.

In another example, the duration of the emission state is set to be about 56ms and the time of the complete duty cycle of one emission state and pause time is set to be 200ms before the display device 10 is lighted.

In general, in the case where the ratio of the duration of the emission state to the duty cycle is set to be greater than or equal to 10%, a duty cycle composed of the sum of the duration of one of the emission states and the duration of one of the suspension states is set between 10ms and 100ms or between 100ms and 200ms, so that the workload of the processing device 30 can be reduced to some extent with a good infrared detection effect.

Further by way of example, the duration of the pause state is set to be the same before and after the display device 10 is illuminated. In other words, the operating state of the infrared emitting unit 201 is maintained before and after the display device 10 is turned on, so as to ensure the stability of the infrared detection performance.

In another modified example, after the display device 10 is turned on, the duration of the pause state is increased by 100ms compared with that before the display device 10 is turned on, so that after the display device 10 is turned on, the infrared emission unit 201 emits the detection wave at a lower frequency, and after the display device 10 is turned off, the frequency of the detection wave emitted by the infrared emission unit 201 is recovered, so that the sensitivity and the response speed of human body proximity sensing in the off-screen state are not affected, and the workload of the processing device 30 can be further reduced by the frequency reduction during the turn-on of the display device 10.

In some embodiments, as shown in fig. 33, the intelligent switch 100 further includes relays 40, the processing device 30 drives on/off of each relay 40 through a relay driving circuit 80, the relays 40 are used for controlling a target circuit for supplying power to a relay device 200, when a certain relay 40 is connected, the relay device 200 connected to the controlled target circuit is powered, and when a certain relay 40 is disconnected, the relay device 200 connected to the target circuit is powered off. Each relay 40 forms a path of control channel, and multiple paths of relay 40 can form multiple paths of control channels, and the switching on and off of relay 40 is the switching of the power supply/power off working state of the corresponding control channel.

An exemplary implementation of the arrangement of the relay 40 in the intelligent switch 100 can be understood with reference to the description of the above embodiment, such as the embodiment shown in fig. 15 and 16.

In the present embodiment, as shown in fig. 34, a circuit schematic diagram of a relay driving circuit 80 is given, and the operation principle thereof is as follows:

when the RELAY 40 control signal RELAY is high, the collector and emitter of the triode Q4 are conducted, the 5V power supply flows to GND (ground) through the triode again through the RELAY 40 coil, the RELAY 40 contacts are attracted, the L (live wire) is connected with the L_OUT (target circuit control line), the L_OUT outputs voltage, and the target circuit is powered on. It should be noted that, when there are multiple control channels, the processing device 30 controls the RELAYs 40 corresponding to the control channels through the multiple control ports, for example, in the following embodiments, the RELAY-1, RELAY-2, RELAY-3 are electrically connected to the processing device 30, and the processing device 30 controls the three RELAYs 40 through the RELAY-1, RELAY-2, RELAY-3.

When the RELAY 40 control signal RELAY is at a low level, the collector and emitter of the triode Q4 are not conducted, no current passes through the RELAY 40 coil, the RELAY 40 contacts are not attracted, the L and L_OUT are not connected, the L_OUT has no voltage output, and the target circuit is disconnected.

When the RELAY 40 control signal RELAY is switched from high to low, the RELAY 40 coil current will not jump, so a reverse potential will be generated, D5 acts as a freewheeling diode to release the coil energy path in order to avoid other components from being damaged.

As shown in fig. 33, the intelligent switch 100 further includes a power supply circuit 50 and a zero-crossing detection circuit 60, wherein the power supply circuit 50 includes a first power conversion circuit 501, a second power conversion circuit 502, and a third power conversion circuit 503. The first power conversion circuit 501 is configured to rectify and convert a power frequency ac (e.g., 220v,50hz ac) into a first power, and the second power conversion circuit 502 and the third power conversion circuit 503 are respectively electrically connected to the first power to respectively convert the first power into a second power and a third power with different voltages. Wherein a first power source is used to power the relay 40 (e.g., 5V), a second power source is used to power the processing module (e.g., 3.3V), and a second and third power source are used to power the display device 10. The power rectified by the first power conversion circuit 501 is further provided to the zero crossing detection circuit 60 for detecting the zero crossing point of the power frequency alternating current, so that the relay 40 acts near the zero crossing point of the alternating current, the surge voltage is reduced, and the service life is prolonged.

In a specific example, as shown in fig. 35, the processing device 30 may employ a MHCB05P-B module from millet company, and the display screen of the display device 10 may employ an OLED display screen, where two voltages are required for power supply, 3.3V and 3.7-4.2V, respectively. The first power conversion circuit 501 may use a power conversion circuit with a PN8016SSC-R1B switching power supply as a core to convert 220V of power frequency ac power into 5V of a first power output, the second power conversion circuit 502 may use an LDO power conversion circuit with a BL1117-33CX as a core to convert 5V of the first power supply into 3.3V of a second power output, the 3.3V power supply is used to supply power to the MHCB05P-B module and the OLED display, and the third power conversion circuit 503 may use an LDO power conversion circuit with a micro-union ME6209a40PG as a core. ME6209a40PG maximum input voltage 18V, fixed output voltage 4V, maximum output current 250mA, packaged with SOT89-3, power Dissipation =500 mW. And has a lower dropout voltage. The LED of the OLED display screen is powered by a third power supply with the maximum power consumption of 65.86mW multiplied by 3= 197.58mW, the maximum current of 49.395mA, and the ME6209A40PG is used for meeting the power supply requirement.

As shown in fig. 36, the zero-crossing detection circuit 60 includes a detection circuit with a triode Q5 as a core, specifically, Q5 is an NPN triode, a collector of the NPN triode is connected to a second power supply through a resistor R76, a base of the NPN triode is connected to a power frequency alternating current through three 100kΩ resistors R30, R31, R32, an emitter is grounded, a resistor R77 and a capacitor C84 are connected in parallel between the emitter and the base, and a collector of the Q5 outputs a zero-crossing detection signal to the processing module through a pin ZVD. The principle of operation is generally described as follows:

When the voltage difference between the L (live wire) and the N (zero wire) of the power frequency alternating current is large, the collector and the emitter of the triode Q5 are conducted, and the ZVD outputs a low level. When the voltage difference between L and N is smaller, the collector and the emitter of the triode Q5 are not conducted, and ZVD outputs a high level. The waveform of ZVD is a 100Hz square wave, and the high-level intermediate point and the low-level intermediate point of the square wave are zero-crossing times, and the MHCB05P-B module controls the on/off operation of the relay 40 based on the zero-crossing times to reduce the surge voltage during the operation.

In some embodiments, as shown in fig. 33 and 35, the smart switch 100 further includes a key, and the display device 10 includes a display screen disposed corresponding to the key.

As shown in fig. 1 to 5, in a specific structure, the display screen is disposed near one end of the key and is divided into a plurality of segments of display areas along the extending direction of the key (as shown in fig. 37), wherein the display area far away from the key is set as a non-display area, the display area near the key is set as a channel indication area for displaying the working state of the control channel where the key is located, and part or all of the display area between the non-display area and the channel indication area is set as a key identification area for displaying key information of the corresponding key; the processing device 30 is further configured to, when detecting that the working state of the control channel corresponding to the key is changed, change the display content of the channel indication area to indicate the current working state of the control channel corresponding to the key, and keep the display content of the key identification area unchanged;

The at least two operating states of the display device 10 include a first state in which no key identification area of all the display screens is displayed and a second state in which the key identification area of at least one display screen is displayed.

Furthermore, the intelligent switch 100 directly indicates the working state of the control channel through a part of the display area on the display screen without separately setting an indication lamp of the control channel of the key. And when the working state of the control channel is changed, the channel indication area in the multi-section display area is locally refreshed, and the key identification area is not refreshed, so that the integral refreshing frequency of the display screen is reduced, and the service life of the display screen is prolonged.

Specifically, each key is correspondingly provided with a relay 40, and the switching of the on-off state of the relay 40 can be triggered by the key. In a specific example, there may be a plurality of keys, where each key is correspondingly provided with a display screen, so that the display screens corresponding to the keys are separated from each other and do not affect each other, and related information (for example, a key function name) of the key is displayed on the display screen corresponding to each key, and the specific display content of the key may be customized by a user through the terminal device, and the customized content is displayed through the display screen, so that the user can freely change the indication information of each key. For example, the intelligent switch 100 includes three keys, and correspondingly, three display screens are also provided for displaying the working states of the control channels corresponding to the three keys. As shown in FIG. 37, each of the display panels was a 0.49 inch OLED display panel having a display area of 11.18mm by 5.58mm and a resolution of 64 by 32. The display screen is divided into a plurality of sections of display areas by taking 4 pixels as a reference from top to bottom, the uppermost 64×8 pixel area is taken as a non-display area, the middle 64×16 pixel area is taken as a channel indication area, and the 64×4 pixel area near the upper side in the lowermost 64×8 pixel area is taken as a key identification area. The channel indication area adopts a word stock with 16 multiplied by 16 pixels, and the channel indication area of each display screen displays 4 Chinese characters or 8 letters at most. The key identification area displays a transverse line, and the working state of the corresponding control channel is indicated through the display and non-display of the transverse line.

In some embodiments, as shown in fig. 35, the word stock uses a word stock chip 70 of hardware, each display screen and the word stock chip 70 communicate with the processing device 30 through an SPI bus, and the processing device 30 performs SPI time-sharing control on the word stock chip 70 and each display screen through a chip select pin.

Further, the infrared receiving unit 202 includes an infrared receiving head for receiving the detection wave, as shown in fig. 31, and in a specific circuit, the infrared receiving unit 202 includes an infrared receiving head (such as the infrared receiving head 2021 shown in fig. 11, the structural scheme of which can be understood with reference to the description of the corresponding embodiment of fig. 11); at least one display screen is arranged between the infrared luminous tube 2012 and the infrared receiving head, so that detection waves emitted by the infrared luminous tube 2012 are blocked by the display screen and directly reach the infrared receiving head through the intelligent switch 100, and internal interference is reduced.

Further, in order to reduce the interference that the detection wave emitted by the infrared light emitting tube 2012 directly passes through the inside of the intelligent switch 100 to reach the infrared receiving head, the power of the infrared light emitting tube 2012 of the infrared emitting unit 201 is set to be less than 250mW.

In a specific example, the infrared light emitting tube 2012 uses an infrared light emitting tube 2012 with a maximum power consumption of 150mW, that is, each driving circuit 2011 adjusts the emission power of the infrared light emitting tube 2012 within a range of 150mW to adjust the detection distance.

Further, for example, the infrared receiving head may be an infrared receiving head with a model XYC-RM504201, and circuits such as amplifying and filtering are integrated therein to realize remote infrared receiving, so that the anti-interference capability is strong, and specific operations are far away from and can be understood by referring to the circuit shown in fig. 31, which is not repeated here.

In some embodiments, the processing device 30 is further configured to:

receiving first index information;

and determining corresponding first text information according to the first index information, displaying the first text information in the channel indication area to indicate keys corresponding to the display screen, wherein the first index information is generated after the user freely defines the names of the keys on the intelligent terminal.

For example, the intelligent switch 100 includes two keys, when the first key is pressed, the corresponding living room light is turned on or off, and when the second key is pressed, the corresponding restaurant light is turned on or off, at this time, the user can define the display content of the display screen close to the first key as "living room light", and the display content of the display screen close to the second key as "restaurant light", so that the display content of the display screen can indicate the operation information corresponding to the two keys respectively, so that the user can distinguish the key functions when using the intelligent switch. The first index information is sent to the intelligent switch 100 by the intelligent terminal, wherein the first index information is determined by the intelligent terminal according to user input, that is, display contents on a display screen of the intelligent switch 100 can be freely configured by a user through the intelligent terminal.

Furthermore, the user can customize the key information of each key according to the actual requirement, and the index information corresponding to the word is sent instead of the dot matrix, so that more word information can be carried in one message, and the method is applicable to communication protocols of short code messages such as Bluetooth.

In a specific example, the word stock chip 70 stores a standard GB2312 word stock, where the stored text information is dot matrix data, and pixels of the dot matrix data are a×b, where a e 12, 16, b e 12, 16, a=b, a represents pixels of the dot matrix data in a horizontal direction, and b represents pixels of the dot matrix data in a vertical direction. Alternatively, a=16, b=16, and the pixels of the dot matrix data are 16×16, that is, when the dot matrix data are displayed on the channel indicating area of the display screen, the pixels in the horizontal direction are 16, and the pixels in the vertical direction are 16.

It should be noted that the byte length occupied by the dot matrix data of a Chinese character is c, where c is e [24, 32]. For example, when the pixels of the dot matrix data are 12×12, the dot matrix data of one kanji occupy 24 bytes; for another example, when the pixels of the dot matrix data are 16×16, the dot matrix data of one kanji occupy 32 bytes. In addition, the pixels of the dot matrix data are a multiplied by b, wherein a is [12, 16], b is [12, 16], and the ranges of a and b enable the dot matrix data to be displayed on the channel indication area of the display screen, so that the display content is proper, and the situation that the display content is unclear due to too small pixels or the display content is too small due to too large pixels is avoided. Setting a equal to b, wherein the pixels in the horizontal direction are the same as the pixels in the vertical direction, so that the dot matrix data of the Chinese characters can be displayed on the display screen of the intelligent switch 100, and the shape of the Chinese characters displayed on the display part is square.

In the configuration process of the channel indication area of each key of the intelligent switch 100, the intelligent device carries the first index information of the text to be configured in the first configuration message and sends the first index information to the intelligent switch 100, and the processing device 30 of the intelligent switch 100 processes the first index information to read the corresponding dot matrix data from the word stock chip 70, and displays the dot matrix data in the channel indication area of the display screen of the corresponding key. It can be understood that if the intelligent terminal directly sends the dot matrix data of the text to be configured to the intelligent switch 100, when the pixels of the dot matrix data are 12×12, the dot matrix data of one kanji occupy 24 bytes, that is to say, 24 bytes need to be transmitted when one kanji is configured; when the pixels of the dot matrix data are 16×16, the dot matrix data of one kanji occupy 32 bytes, that is, 32 bytes need to be transmitted to configure one kanji. If the intelligent terminal sends the first index information of the text to be configured to the intelligent switch 100, when the first index information is Unicode code, the Unicode code of a Chinese character occupies 2 to 4 bytes, that is, only 2 to 4 bytes need to be transmitted for configuring a Chinese character; when the first index information is the GB2312 code, the GB2312 code of one chinese character occupies only 2 bytes, that is, only 2 bytes need to be transmitted to configure one chinese character. Therefore, the number of bytes occupied by the index information is smaller than the number of bytes occupied by the dot matrix data, so that the number of words of the text to be configured, which can be carried in one first configuration message when the index information is transmitted, is redundant to the number of words of the text to be configured, which can be carried in one first configuration message when the dot matrix data is transmitted, and thus, the intelligent terminal sends the index information to the intelligent switch 100 instead of the dot matrix data, and communication resources can be saved.

Further, for example, the intelligent terminal is directly connected to the intelligent switch 100 through bluetooth, and then the first configuration message is a bluetooth message, and a maximum of 31 bytes are used for transmitting data in one bluetooth message. The dot matrix data of one Chinese character occupies at least 24 bytes, so that one first configuration message can be transmitted to the dot matrix data of at most one Chinese character. The first index information of a Chinese character occupies 2 to 4 bytes, and when the first index information occupies 2 bytes, a first configuration message can be transmitted to 15 Chinese characters at most; when occupying 3 bytes, a first configuration message can be transmitted to 10 Chinese characters at most; when 4 bytes are occupied, one first configuration message can be transmitted to 7 Chinese characters at most, and comprehensively known that one first configuration message can be configured for a plurality of Chinese characters. In this way, the intelligent terminal sends the index information to the intelligent switch 100 through the bluetooth message instead of the lattice data, so that communication resources can be saved.

In an alternative embodiment, the first index information is GB2312 code, the first text information is dot matrix data, that is, the word stock chip 70 of the smart switch 100 stores dot matrix data of all the chinese characters in the GB2312 code table, and all the dot matrix data are arranged according to the order of all the chinese characters in the GB2312 code table.

Further, the processing device 30 determines corresponding first text information according to the first index information, and displays the first text information in the channel indication area, which is specifically configured to:

the processing device 30 calculates a storage address according to the GB2312 code corresponding to the first index information, where the storage address is a start address of storing the dot matrix data corresponding to the input chinese character in the word stock chip 70, and then reads data with a specified byte length from the word stock chip 70 with the storage address as a start, so as to obtain the dot matrix data corresponding to the input chinese character, where the specified byte length is a byte length occupied by the dot matrix data of one chinese character. And then, the dot matrix data is sent to a corresponding display screen for display.

Further, the first index information is generated after the user freely defines the names of the keys on the intelligent terminal, and specifically may be for example:

the user inputs key information corresponding to each key through a man-machine interaction interface (provided by an application program corresponding to the intelligent switch 100) of the intelligent terminal, the intelligent terminal obtains a text to be configured corresponding to each key information, and first index information is obtained based on the text to be configured;

The user triggers the intelligent terminal by clicking the information synchronization control displayed on the man-machine interaction interface of the intelligent terminal, so that the intelligent terminal and the intelligent switch 100 establish a Bluetooth direct connection relationship; the man-machine interaction interface where the information synchronization control is located and the man-machine interaction interface where the input key information is located can be the same or different man-machine interaction interfaces;

then the first index information is sent to the intelligent switch 100;

the intelligent switch 100 processes the first index information, reads the corresponding first text information from the word stock chip 70, and displays the first text information in the channel indication area of the display screen of the corresponding key. The text content of the first text information representation is consistent with the text to be configured input by the user, so that after the first text information is displayed in the channel indication area, the display content of the display screen of each key is also consistent with the text to be configured input by the user.

Thereafter, the processing device 30 of the smart switch 100 stores the first index information.

In a specific embodiment, after receiving the first index information sent by the intelligent terminal, the intelligent switch 100 stores the first index information in the memory, and configures display content on the display screen according to the first index information, so that the display content on the channel indication area corresponding to the display screen of each key is consistent with the content input by the user on the intelligent terminal. In this way, in the case that the intelligent switch 100 is powered up again after power failure, the intelligent switch 100 can update the display content of the channel indication area of each display screen according to the first index information stored in the memory, so that the display content successfully configured by the user last time is displayed on each display screen, and the user is not required to reconfigure.

In a specific example, the smart switch 100 presets the display content of each display screen when leaving the factory, for example, a "key one, a key two, a key three, etc., when a user purchases and takes the smart switch 100, the smart switch 100 will automatically enter a network distribution mode when first powering up so that the user can quickly distribute the network, before the user does not change the key names of each key (i.e. the display content of the display screen corresponding to each key) through the mobile phone, the preset display content will be displayed on each display screen by default, when the user distributes the network for the smart switch 100 through the mobile phone, the key names of each key can be modified through the app interface on the mobile phone, and the modified key names on the mobile phone are sent to the smart switch 100 through the triggering operation of the key name synchronization, so that the key name information modified by the user is displayed on each display screen of the smart switch 100.

In addition, the existing multi-path intelligent switch supports that the multi-path control channels are simultaneously opened, for example, three control channels of one three-path intelligent switch respectively control three lamps, so that the three-path intelligent switch supports that the three control channels are simultaneously opened and three lamps are simultaneously opened. However, for some electrical devices having multiple gear positions, such as a fresh air fan, an electric fan, etc., the existing intelligent switch does not have a good solution to adapt to the selective switching of multiple gear positions of the same electrical device, so that the intelligent switch causes obstruction in application and popularization of the electrical devices, and a user needs to purchase a dedicated controller separately if he wants to control the electrical devices, which causes inconvenience.

Based on this, in an embodiment of the present invention, an intelligent switch is provided, which has a first mode, so that the intelligent switch in the first mode can lock a plurality of operation areas into a trigger state, so as to be suitable for a selected switching application scenario among a plurality of gears of the same electrical equipment. The intelligent switch 100 provided in this embodiment focuses on the description of hardware and software, and the corresponding structural scheme is applicable to the intelligent switch 100 described in any of the embodiments shown in fig. 1 to 37. Further, the embodiments corresponding to the software and/or hardware aspects of the intelligent switch 100 provided in this embodiment can be combined with the configuration aspects of the intelligent switch 100 described in any of the embodiments described above with reference to fig. 1 to 24, and the intelligent switch 100 described with reference to fig. 25 to 37.

Referring to fig. 38, an intelligent switch according to an embodiment of the invention at least includes a processing device 30 and at least two on-off devices 90. Wherein the on-off device 90 has an on-state and an off-state, and the processing device 30 is configured to control the on-off state of the on-off device 90.

In some embodiments, the processing device 30 is configured to switchably operate in a first mode and a third mode; locking the on-off devices 90 in a first mode to select a trigger state such that at most one on-off device 90 is allowed to enter an on-state at the same time of the at least two on-off devices 90; in the third mode, two or more on-off devices 90 are allowed to be on at the same time.

In other words, the first mode of the processing device 30 may be freely selected by the user as an option, and when the user sets the processing device 30 to a non-first mode (e.g., the third mode), the intelligent switch has a function of a general intelligent switch, which can be suitable for a general intelligent control scenario (e.g., a light control scenario), and when the user sets the processing device 30 to the first mode, the intelligent switch is locked to a trigger state, which can be suitable for some special application scenarios (e.g., a selection switching application scenario among a plurality of gears of the same electrical apparatus such as the above-mentioned fresh air fan). Due to the introduction of the first mode, the control object and the use scene of the intelligent switch provided by the embodiment are more diversified, and more free choices are provided for users.

In the first mode, the on-off devices 90 of the intelligent switch can only be turned on at the same time, and the on-off devices 90 cannot be turned on at the same time, so that the on-off devices 90 of the intelligent switch have a state of alternative triggering to adapt to an alternative switching application scenario among a plurality of gears of the same electrical equipment.

Further, in some embodiments, the intelligent switch is adapted to be connected to a target circuit and used for controlling the target circuit through the on-off device 90, so as to control on-off of circuits of a plurality of gears of the multi-gear device based on the plurality of on-off devices 90 of the intelligent switch respectively when the multi-gear device is connected to the target circuit; in the first mode, the processing device 30 of the intelligent switch locks the on-off device 90 in a selectively triggered state, so that at most only one on-off device 90 of the at least two on-off devices 90 is allowed to enter the on-state at the same time, thereby selectively triggering a plurality of gears of the multi-gear device.

The triggering of the plurality of gear positions of the electrical device is understood to mean controlling the switching on and off of the corresponding gear positions, for example controlling a certain gear position to be switched from off to on or from on to off.

Further, in the first mode, the processing device 30 is specifically configured to: when receiving the control for indicating the switching of the on/off device 90 to the on state, if there is another on/off device 90 in the on state, the other on/off device 90 is switched to the off state, and then the on/off device 90 is switched to the on state. Specifically, the processing device 30 will first turn off the already turned on-off device 90 when turning on a new on-off device 90, so as to avoid simultaneously turning on two on-off devices 90 at the same time.

In some embodiments, as shown in fig. 39, the on-off device 90 includes:

the electronic switch is used for receiving the operation areas and is correspondingly arranged in each operation area;

wherein the processing means 30 are able to detect the manipulation applied to the operating zone and control the on and off of the corresponding electronic switch accordingly; wherein the electronic switch is turned on to form an on state corresponding to the on-off device 90 and is turned off to form an off state corresponding to the on-off device 90.

The operation area may be understood as an area for receiving user manipulation, for example, when the smart switch is implemented as a key switch, and may be, for example, a key operation area formed by a key 21 of the key switch (e.g., the key 21 capable of being manipulated to be displaced in the embodiment shown in fig. 1 to 10); when the smart switch is implemented as a touch switch, the operation region may be, for example, a designated touch region on a touch panel of the touch switch; when the intelligent switch is implemented as a screen switch, the operation area may be, for example, an operation area where an operation control virtualized on a touch screen of the screen switch is located. Further, the manipulation may be, for example, a manipulation of pressing/releasing a key, a manipulation of touching/approaching to sense a touch area, a touch screen manipulation, or the like. In summary, the definition of the operation area and the corresponding operation type will be different according to the types of the intelligent switches, however, no matter how the implementation form and the principle of the operation area are changed, any operation area formed by any structure capable of generating a trigger signal based on the user operation in the field should not deviate from the scope of the embodiment of the present invention as long as the area is used for receiving the user operation to trigger the intelligent switches, which is an alternative of the embodiment of the present invention.

The electronic switch is understood to mean an element or a combination of elements having an on-state and an off-state, for example an electronic switch with a relay or a thyristor as an actuating element, which is connected to a target circuit for controlling the switching on and off of a supply circuit of an electrical appliance which is powered by the target circuit. The electronic switch enters an on state, the target circuit is turned on and the electrical device is powered, and the electronic switch enters an off state, the target circuit is turned off and the electrical device is powered off.

For example, if the intelligent switch has three on-off devices 90:

when the intelligent switch is used in a lamp control scene, the processing device 30 can be set to a third mode, the electronic switches corresponding to the three on-off devices 90 are respectively connected with three lamps, and the corresponding three operation areas are respectively used for triggering the power on and power off of a control channel formed by the corresponding electronic switches so as to control the on-off of the lamps corresponding to the control channel; in a third mode, the intelligent switch supports the three electronic switches to be turned on simultaneously so as to turn on three lamps simultaneously.

For example, when the control object of the smart switch is a fresh air machine, the processing device 30 may be set to a first mode; three electronic switches corresponding to the three on-off devices 90 of the intelligent switch respectively control the high, medium and low gears of the fresh air ventilator. It is known to those skilled in the art that three gears of the new wind turbine are alternatively triggered at the same time, i.e., the new wind turbine does not open two gears simultaneously (e.g., open a high gear and a low gear simultaneously), otherwise the service life of the new wind turbine is affected. However, the existing intelligent switch is not suitable for such a scenario because it supports simultaneous opening of a plurality of control channels. According to the intelligent switch provided by the embodiment, in the first mode, at most, only the electronic switch corresponding to one operation area is allowed to be connected at most at each time, and the alternative trigger of the same time period of a plurality of gears of the new fan can be well adapted.

Specifically, each operation area of the intelligent switch is provided with a detection switch, and the application of the control to the operation area can trigger the corresponding detection switch, so as to transmit the corresponding trigger signal to the processing device 30, so that the processing device 30 can identify the operation area to which the control is applied, and accordingly control the on and off of the corresponding electronic switch. The trigger signal is understood to be any electrical signal that can be recognized by the processing means 30. In a specific example, when the operation area is set as a designated touch area of the touch panel, the detection switch may be, for example, a sensing electrode of a capacitive proximity sensing chip coupled to the touch panel; when the operation area is set as the key 21, the detection switch may be, for example, a tact switch, the key 21 directly or indirectly abuts against the tact switch, the key 21 may be pressed to displace and can be released to reset, and the user can trigger the tact switch by pressing the key 21.

Further, the processing device 30 is further configured to: in the third mode, the operation modes are allowed to be switched independently of each other between the operation areas; the working modes comprise an on-off mode and a wireless mode.

The operation area is used for receiving control under the on-off mode so as to switch the on-off state of the corresponding electronic switch; in the on-off mode, the operation area is equivalent to a mechanical key of a traditional mechanical switch and is used for switching on and off of a corresponding control channel. The operation area is used for receiving control to send specified wireless signals outwards in a wireless mode, wherein an electronic switch corresponding to the operation area in the wireless mode is kept in an on state and cannot be disconnected according to the control accepted by the operation area, so that the intelligent equipment connected to the electronic switch is prevented from being powered off to be disconnected. The wireless signal may be a control message programmed based on a predetermined protocol to perform a control operation on a target controlled device (the target controlled device may be an electrical device connected to the target circuit, or may be other electrical devices that can directly or indirectly establish a controlled or controlled relationship with the intelligent switch, for example, an intelligent device that accesses a network where the same gateway is located and joins the same gateway).

Further, unlike the global effect of the first mode in the above embodiment (i.e., the first mode is entered in units of intelligent switches, all the functions of the operation areas are affected once the first mode is entered), the operation modes of the operation areas in this embodiment support local switching, i.e., switching in units of operation areas, and the operation mode switching of each operation area can be independently performed without affecting each other, so as to enrich the control forms of the intelligent switches of the multiple operation areas. The user can set corresponding working modes for each operation area according to specific application scenes and control objects. Furthermore, each operation area can enter an on-off mode to have an on-off control function of a conventional mechanical switch, and can enter a wireless mode to expand target equipment, so that the controlled terminal is not limited to target equipment directly and electrically connected with an electronic switch of an intelligent switch. For example, if the intelligent switch has three operation areas and the control object has only two lamps, two of the three operation areas are set to be on-off mode for controlling the on-off of the two lamps, and the other is set to be wireless mode for controlling other intelligent devices.

In some embodiments, the processing device 30 is further configured to lock all operating areas to the on-off mode in the first mode, and if there is an operating area in the wireless mode before entering the first mode, entering the first mode triggers the processing device 30 to forcibly switch all operating areas in the wireless mode to the on-off mode. In other words, in this embodiment, the first mode will enjoy a higher priority, so that all the operation areas in the first mode are forced to enter the on-off mode, the operation areas set to the wireless mode will also be forced to switch to the on-off mode, some of the intelligent scenes defined by the user and associated with the wireless modes of the operation areas will also fail, and the intelligent switch at this time can be regarded as a gear change switch dedicated to the multi-gear device.

In some embodiments, the processing device 30 is further configured to force the electronic switches corresponding to all the operation areas to be switched to the off state when the first mode is entered from the non-first mode.

Furthermore, when the intelligent switch is triggered from the non-first mode to enter the first mode (for example, enters the first mode from the third mode), all the electronic switches are uniformly switched to the off state no matter how many electronic switches are in the on state before, so that when the intelligent switch initially enters the first mode, the control channels of the operation areas of the intelligent switch are all in the off state, and further, the electrical equipment connected with the intelligent switch is in the off state, so that the user can conveniently operate the intelligent switch subsequently.

In some embodiments, the processing device 30 can be configured to have a second mode; and in the second mode, locking the on states of the electronic switches corresponding to all the operation areas in the wireless mode, so that the electronic switches in the second mode are not disconnected by other communication instructions except the first mode.

The communication command referred to herein may be, for example, a voice control command from a smart speaker, a control command for switching the on/off state of an electronic switch for switching an operation area in a wireless mode transmitted by a mobile phone, a control command from a wireless switch paired with a smart switch or a wall switch, or the like.

That is, in the second mode, the electronic switch corresponding to the operation area set to the wireless mode is neither turned off by the manipulation of the user nor by the communication instruction other than the first mode. In some application scenarios, the intelligent switch is connected to a target circuit, and the target circuit is connected to at least one intelligent device, if the corresponding electronic switch is disconnected, the intelligent device is powered off and is offline, so that inconvenience is caused to a user. At the moment, the problem can be solved by entering the second mode, and the on state of the electronic switch corresponding to the operation area of the wireless mode in the second mode is locked, so that the problem that the intelligent equipment is always powered off and off in some application scenes is solved, and the limitation of the use scenes of the intelligent switch is improved. And the user can control whether the intelligent switch enters the second mode through the terminal equipment, so that the freedom degree of selection of the user is improved.

In this embodiment, the first mode has a higher priority than the second mode, that is, in the case that the intelligent switch enters the first mode, all the operation areas will be forced to enter the on-off mode, and the operation area set to the wireless mode will be forced to switch to the on-off mode, resulting in the failure of the second mode.

In some embodiments, the processing device 30 is capable of establishing a communication connection with an external terminal device and is capable of implementing at least one of the following controls based on manipulation of the terminal device:

switching to a first mode, a second mode or a third mode according to a first control instruction from a terminal device establishing a communication connection relationship;

in the second mode or the third mode, the working modes of the operation areas are switched independently according to a second control instruction of the terminal equipment;

in the first mode and the third mode, the on state and the off state of the electronic switch in the operation area of the on-off mode are switched according to a third control instruction of the terminal equipment, and in the first mode, one electronic switch can still be switched on at most at the same time through the third control instruction;

wherein the first control command, the second control command and the third control command are all compiled according to a predetermined communication protocol and are different from each other.

In an alternative embodiment, as shown in fig. 40, the first control command, the second control command, and the third control command may originate from an application program of a terminal device (for example, a mobile APP matched with the smart switch). Specifically, the application program has an interface, and the configuration options of the intelligent switch are displayed on the interface. For example, a control of a first mode and a second mode which can be clicked is displayed on the interface, when a user clicks the corresponding control to open the control, the application program generates and sends out a corresponding control instruction based on the mode corresponding to the clicked control, so that the intelligent switch enters a corresponding working mode.

Further, the processing device 30 has a communication function (such as an external bluetooth communication unit, or a bluetooth module integrated with communication and processing functions), and can establish a communication connection relationship with a terminal device by means of a distribution network. Specifically: the processing device 30 has a distribution network mode, and in the distribution network mode, a message sent by the processing device 30 of the intelligent switch due to the operation area being controlled may be a distribution network message, where the distribution network message is used to trigger the designated device to add the intelligent switch to the target network. The network distribution mode can be understood as a mode in which the intelligent switch is suitable for distributing network with the target network so as to join in the target network.

In a specific example, the processing device 30 of the intelligent switch includes a bluetooth module, which communicates outside through a BLE MESH, the operation area includes a key 21, the intelligent switch can enter a distribution network mode in response to a designated distribution network operation, and in the distribution network mode, the processing device 30 sends a predefined distribution network message to the outside, where the distribution network message is used for the bluetooth gateway or the terminal device to search for the intelligent switch and display the intelligent switch on an app interface, and a user triggers a predetermined distribution network operation of the intelligent switch by clicking the intelligent switch, so that the intelligent switch accesses to a target network through the bluetooth gateway. After the intelligent switch is connected to the target network, a control and/or controlled relation can be established with other intelligent devices connected to the target network, so that the use scene of the intelligent switch is enriched.

Further by way of example, the designated distribution network manipulation may be, for example:

double clicking any key 21 (continuously clicking the key 21 twice within 500 ms), continuously flashing for 2 times within 1.2s corresponding to the indication mark after the double clicking is successful, and indicating that the intelligent switch enters a pre-reset state:

if the key 21 is pressed for 3 rd time within 1.2s, the indication mark stops flashing, and then if the key 21 is continuously pressed for more than 5s for 3 rd time, the indication mark restarts flashing after 5s, which indicates that the network distribution mode is successfully entered;

If no key 21 is pressed within 1.2s, the flashing is not performed after the flashing is finished;

if the key 21 is pressed but normally released (i.e. not kept pressed for more than 5S) within the 1.2S, a normal turning action is triggered (i.e. the electronic switch corresponding to the key 21 is triggered to turn from the current state to another state, for example from the current on state to the off state), and the indication mark also stops flashing.

Further, the processing device 30 further has a pairing mode, wherein the pairing mode in this embodiment is in operation area units, different from the global effect of the network distribution mode in the above embodiment (i.e. the network distribution mode is a network distribution operation in intelligent switch units).

For example, when the operation area is implemented as the key 21, the user can enter the pairing mode of the key 21 by pressing more than a certain key 3S for a long time, at this time, the user clicks a key 21 of a wireless switch to make the wireless switch send out a corresponding pairing message, so that the intelligent switch can receive the pairing message and store the ID (for example, a preset serial number for uniquely identifying the wireless switch) of the wireless switch carried in the pairing message, so as to realize pairing between the key 21 of the intelligent switch and the corresponding key 21 of the wireless switch, and then the control channel where the corresponding key 21 of the intelligent switch is located can be controlled by the key 21 of the wireless switch.

In another example, when the operation area is implemented as the key 21, the user can make the intelligent switch enter the pairing mode of the key 21 by clicking a certain key 21, and at this time, the user presses more than one key 3S of the other intelligent switch for a long time so that the other intelligent switch also enters the pairing mode of the corresponding key 21, so that mutual control pairing of the corresponding keys 21 of the two intelligent switches can be achieved, and then the corresponding key 21 of the other intelligent switch can be controlled through the corresponding key 21 of one intelligent switch. If one of the intelligent switches enters the first mode, the two intelligent switches still follow the relevant control logic of the first mode when controlling each other.

By way of further example, the pairing step of intelligent switch a and intelligent switch B may be, for example: pressing the first key 3S of the A for a long time to enter a pairing mode, pressing the second key 3S of the B at the moment to finish pairing with the first key of the A, and sending a corresponding indication signal by the intelligent switch after the pairing is successful to prompt successful mutual control learning, wherein in the follow-up control, the states of an electronic switch corresponding to the first key of the A and an electronic switch corresponding to the second key of the B are completely synchronous; if the key of one of the intelligent switches enters the wireless mode, the synchronous state is not continued.

The pairing steps of intelligent switch a, intelligent switch B, intelligent switch C may be, for example: if A, B is already paired, C wants to pair with A, B, and only C and A (or B) need to pair, then the pairing of the corresponding keys 21 of the three intelligent switches of A, B, C is successful, and the states of the corresponding electronic switches, the indicator light and the APP of the three are completely synchronous; if the corresponding key 21 of one of the smart switches enters wireless mode, the state is no longer synchronized.

If the intelligent switch A and the intelligent switch B are successfully paired, the intelligent switch C and the intelligent switch D are successfully paired, and the intelligent switch A and the intelligent switch D cannot be paired when the intelligent switch A and the intelligent switch D are paired. At least one of a or C must be purged of the existing pairing relationships to again pair A, C. Examples: the pairing is cleared by long-pressing the corresponding key 21 of A, and then the pairing A is carried out, and A, C, D is synchronous at the moment; or the corresponding key 21 of the long-time pressing C clears the pairing and then pairs A, C, and A, B, C is synchronous at the moment; or simultaneously clears the pairing of the corresponding keys 21 of A, C and then pairs A, C, at which point A, C are synchronized.

For example, when a key 21 is pressed for 12S or more, the pairing relationship under the key 21 can be cleared, including the pairing relationship of paired wireless switches and the pairing relationship of paired intelligent switches.

Referring to fig. 41, the present invention further provides an intelligent control system, which is characterized by comprising an intelligent switch and a multi-gear device.

The multi-gear device is understood to be an electrical device having at least two gears, where the multiple gears are respectively used to control the electrical device to enter different working states, and the multiple gears are generally triggered alternatively, and in a specific example, the multi-gear device may be a fresh air fan or a ceiling fan (electric fan), and further the multiple gears are respectively a high wind speed gear, a medium wind speed gear and a low wind speed gear, and the different working states may be a high wind speed working state, a medium wind speed working state and a low wind speed working state.

The intelligent switch may be, for example, an intelligent switch as described in the foregoing embodiment, where the multiple on-off devices 90 of the intelligent switch are respectively used to control on-off of each gear of the multi-gear device, so as to control on-off of each gear of the multi-gear device through each on-off device 90 of the intelligent switch; wherein the smart switch is adapted to be configured into a first mode so that at most only one gear of the multi-gear device is turned on at the same time.

Furthermore, the intelligent switch still has the function of a common intelligent switch in a non-first mode, and in the first mode, the intelligent switch is equivalent to a special switch special for the multi-gear device, so that a user can freely change the functional mode of the intelligent switch according to different use environments without specially configuring the switch for the multi-gear device.

The following further describes an embodiment of the present invention by taking the multi-gear device as a new fan as an example:

referring to fig. 42, a control block diagram between the intelligent switch and the fresh air fan is shown;

specifically, as shown in fig. 42, each of the on-off devices 90 is correspondingly provided with an operation area and an electronic switch, and further, the intelligent switch may include three on-off devices 90, where the electronic switches correspond to the electronic switch 1, the electronic switch 2, and the electronic switch 3 in the figure.

The intelligent switch includes a first power supply terminal (e.g., a neutral N input terminal) and a second power supply terminal (e.g., a hot L input terminal). The first power terminal is used to connect with a common terminal, such as a zero line terminal, of the fresh air fan, and the second power terminal is used to supply power to the processing device 30 (for example, to convert the input ac power into 5V dc power) and to supply power to the on-off device 90 at the same time. The three output ends of the intelligent switch are respectively and electrically connected with the three control ends of the new fan, namely, the three air outlet parameter control lines H, M, L of the new fan, for example, the three output ends of the intelligent switch can represent three wind speed gears of the new fan, namely, high, medium and low gears. The three electronic switches are also electrically connected to the processing device 30 through RELAY-1, RELAY-2, RELAY-3, respectively, to receive the control signals sent by the processing device 30.

According to the embodiment of the present disclosure, each electronic switch is driven by the processing device 30 through a driving circuit (as shown in fig. 33 to 35, and the relay 40 shown in fig. 15 and 16 is used as the electronic switch, and the relay driving circuit 80 is used as the driving circuit); the driving circuit is configured to be able to control on and off of each electronic switch based on the control signal. The live input of the intelligent switch also supplies power (e.g., converts the input ac power to 5V dc power) to the power supply circuit 50 (e.g., the first power conversion circuit 501 shown in fig. 33, which provides the first power to the electronic switch). The driving circuit is electrically connected to the processing device 30, receives control signals input by the processing device 30 through RELAY-1, RELAY-2 and RELAY-3, and controls on and off of each electronic switch based on the control signals. Furthermore, the processing device 30 can drive the independent electronic switches to be closed through RELAY-1, RELAY-2 and RELAY-3 so as to control the working state of the fresh air fan. For example, the driving circuit may drive the connection and disconnection of the output end and the power supply end according to the control signal sent by the processing device 30, so as to control the connection and disconnection of the air outlet parameter control line H of the fresh air fan, and further control the working state of the fresh air fan.

In the first mode, the intelligent switch is equivalent to a fan controller dedicated to the fresh air fan, the processing device 30 of the intelligent switch turns on at most one path of electronic switch at the same time, for example, when the electronic switch 1 corresponding to the operation area 1 is turned on, if the processing device 30 detects the control on the operation area 2, the electronic switch 1 is triggered to be turned off through RELAY-1, then the electronic switch 2 is triggered to be turned on through RELAY-2, and the working state of the fresh air fan is further represented as that a high wind speed gear is turned off while a medium wind speed gear is turned on, that is, three wind speed gears can still follow the control logic that the gears are triggered alternatively when the intelligent switch controlled by a plurality of operation areas.

Alternatively, the electronic switch is configured as a relay (e.g., relay 40 shown in fig. 33-35, 15, 16, corresponding driving circuit may be e.g., relay driving circuit 80 shown in fig. 33-35, and specific circuit principles may be understood with reference to the corresponding embodiments shown in fig. 33-35). Each relay comprises a magnetic control electrode pair, and the magnetic control electrode pair is electrically connected with the fresh air blower through an air outlet parameter control line; the magnetic control electrode pair comprises two conductive contacts, if the two conductive contacts in the magnetic control electrode pair are connected, the air outlet parameter control line is connected, and the fan works under the air outlet parameter; if the two conductive contacts in the magnetic control electrode pair are not connected, the air outlet parameter control line is powered off.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
