Description

An outdoor handheld control device for remote control traffic lights

technical field

The utility model relates to the field of information interaction, in particular to an outdoor hand-held control device for remote-controlled traffic lights.

Background technique

With the increase of vehicles, more and more roads appear, and with the increase of the number of roads, the connection of each road is more and more complicated and close. When a vehicle needs to pass through the intersection of two roads, it is usually controlled by traffic lights to indicate when vehicles in different directions can pass and when they need to wait, thereby avoiding traffic accidents and ensuring efficient use of the road.

At the intersection, red, yellow, green and three-color traffic lights are hung on all sides. Traffic lights are internationally unified traffic lights. A red light is a stop signal and a green light is a go signal. At the intersection, cars from several directions gather here, and some will go straight, and some will turn. The specific rules of passage are determined by traffic lights. When the red light is on, it is forbidden to go straight or turn left, and vehicles are allowed to turn right under the condition of not hindering pedestrians and vehicles; when the green light is on, vehicles are allowed to go straight or turn; When the yellow light flashes, it warns the vehicle to pay attention to safety.

Usually, the way to control the traffic lights is controlled according to the time. The lamps are controlled by the traffic signal machine (the device that produces the three colors of red, green and blue lights), and run according to the preset timing scheme, also known as fixed cycle control. One day with only one timing scheme is called single-stage timing control; one day using several timing schemes according to the traffic volume at different times is called multi-stage timing control. For example, the alternating time between red light and green light can be set to 30 seconds, that is, the north-south green light at the intersection will be on for 30 seconds, at this time, the east-west red light will be measured for 30 seconds; after the 30 seconds, the east-west green light will be on For 30 seconds, the north-south red light will be on for 30 seconds; after that, the cycle will be repeated.

In addition to controlling the traffic lights according to the time, it can also be controlled manually, that is, by directly issuing switching instructions to the signal machine, so that the traffic lights can be changed in a timely manner to ensure the normal traffic order. For example, if there is congestion at a certain crossroad, vehicles traveling east-west are blocked to the center of the crossroad. At this time, the north-south traffic light should not be controlled to turn green, otherwise the congestion situation will easily worsen. At this time Also just can be manually controlled the change of traffic signal light by traffic policeman.

There are two ways for the police to manually control the signal. The first is to manually input through the buttons on the manual panel of the signal to change the traffic signal to the required state; the second is to control the signal remotely. The user remotely controls the signal by using the handheld controller to change the traffic signal to a desired state.

After the police finish the manual control, the operable signal machine returns to the automatic operation state.

Using the remote signal control method, that is, the traffic police remotely send instructions to the adapter through an outdoor handheld control device, so that the adapter controls the traffic signal machine to perform corresponding actions. Because the device is carried by the police at any time and used on the move, it is required to have high reliability and applicability in actual work.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. . The components of the embodiments of the invention generally described and illustrated in the figures herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of the present utility model.

The embodiment of the utility model provides an outdoor handheld control device for remote control traffic lights, as shown in Figure 1, comprising: a sealed waterproof casing 2, a control chip arranged inside the casing 2; Groove 11, an insulating waterproof plug matched with the groove 11 and a charging interface 1; buttons and a liquid crystal display, etc.

The control chip includes a power module connected to the charging interface 1;

The charging interface 1 is located in a closed space formed by cooperation of the groove 11 and the insulating waterproof plug.

Specifically, the groove 11 is embedded in the housing 2, and the charging interface 1 is located inside the groove 11 (that is, the charging interface 1 is located in the closed space formed by the cooperation of the groove 11 and the insulating plug), which ensures that the charging interface 1 is always It is located inside the casing 2, thereby ensuring that the charging interface 1 is difficult to be damaged by external objects. And with the insulating plug, the insulating plug can cooperate with the groove 11 to form a closed space, which ensures that the insulating plug can withstand a certain degree of foreign object attack for the charging interface 1 . Specifically, the charging interface 1 may be a USB interface, or a similar interface capable of being electrically connected to an external power source.

Usually the insulating plug is an object similar to a baffle. If it is used alone, as the use time prolongs, the user may drop the insulating plug or forget it somewhere, resulting in the disappearance of the insulating plug. After disappearing, the charging interface 1 will be directly exposed to natural conditions again, and the attack of foreign objects will directly act on the charging interface 1, resulting in accelerated aging of the charging interface 1 again. In order to avoid this phenomenon, a connector can be used to connect the housing 2 and the insulating plug to ensure that the insulating plug is still connected to the housing 2 during charging (when the insulating plug is removed from the groove 11) Therefore, the insulating plug is not easy to be forgotten, so that the insulating plug can provide more effective protection for the charging interface 1 .

Specifically, the insulating plug can be made of insulating rubber, and the matching position of the insulating plug and the groove 11 can be clamped, so as to ensure that the insulating plug can be effectively combined with the groove 11 and prevent the insulating plug from falling off from the groove 11. The connecting piece connecting the insulating plug to the housing 2 is preferably a flexible connecting piece, such as a connection structure integrated with the rubber waterproof plug and made of the same material, or a nylon cloth rope, a metal chain, and the like. This enables the insulating plug to have more free space to move, and also prolongs the service life of the insulating plug to a certain extent.

In order to make the use of the charging interface 1 more flexible, the charging interface 1 can be designed to be movable. For example, when the charging interface 1 can be connected to the power module of the control chip, the power module is arranged on the control chip, that is, when When the position of the control chip is relatively fixed, the position of the power module is also relatively fixed (the relatively fixed position mentioned here is explained with the shell as a reference), and the power module is usually connected to the charging interface 1 through an electrical connection line In some cases, the external power supply is also recessed in a certain gap. If the charging interface 1 is always inside the casing 2, it is not easy to use the charging interface 1 to supply power to the power module. Thus, the power supply module and the charging interface 1 may be connected through an extendable power cord, and by setting up an extendable power cord, when necessary, the charging interface 1 may extend out of the casing 2 and be connected to an external power source to complete the charging process. Power supply to the power module. And after the power supply to the power module is completed, the extendable power cord can be shrunk to the inside of the casing 2, which will not affect the normal use of an outdoor hand-held control device for remote-controlled traffic lights.

Furthermore, the outdoor handheld control device for remote-controlled traffic lights provided by the utility model also includes a rubber protective layer 3 arranged on the outer periphery of the housing 2 .

The purpose of setting the rubber protective layer 3 is to reduce the external impact on the overall outdoor hand-held control device for remote-controlled traffic lights, and ensure the safety of the overall fuselage of the outdoor hand-held control device for remote-controlled traffic lights. The rubber protection layer 3 can be in the shape of a circle and is sheathed on the casing.

Specifically, the outdoor handheld control device for remote-controlled traffic lights provided by the utility model also includes a power button 4 arranged on the surface of the casing 2, and the power button 4 is electrically connected to the control chip.

Usually, the keys of the outdoor hand-held control device for remote-controlling traffic lights are arranged on the same side of the housing 2, and the keys include signal light control keys and remote control function keys. However, if functional buttons such as power supply and general signal light control buttons are arranged on the same surface area, it is easy to press functional buttons such as power supply by mistake when using signal light control buttons on a daily basis. Thus, functional keys such as power supply, menu setting, and automatic return can be arranged on different surfaces of the outdoor hand-held control device housing 2 for remote traffic lights, and can be designed as raised keys and recessed keys for different key functions.

Furthermore, the utility model provides an outdoor handheld control device for remote control traffic lights. When the recessed key is not under force, the top surface of the recessed key sinks into the outer surface of the housing 2 .

The recessed buttons are generally used for functions such as power switch, automatic return, menu setting, etc., to prevent them from being accidentally touched to produce bad control results. When the recessed key is under no force, its top surface sinks into the outer surface of the housing 2, which ensures that the recessed key is always lower than the outer surface of the housing 2 (the lower here means closer to the inside of the housing 2 ). Usually, when the user makes a wrong operation, it is easier to press the buttons protruding from the surface of the housing 2 , and relatively speaking, it is less easy to press the buttons lower than the surface of the housing 2 .

Further, the housing 2 is a hollow rectangular cavity, and a liquid crystal display 5 is arranged on the front of the housing 2, and the liquid crystal display 5 is electrically connected to the control chip;

A connection part 10 is also provided on the back of the housing 2, and the connection part 10 includes a belt card, a detachable fixing belt and a fixed suction cup.

The front of the housing 2 is one side of the housing 2 , and generally, the side of the housing 2 having a hollow rectangular cavity with a larger surface area is used as the front. There could be more room on the front for display and input buttons.

In order to make an outdoor hand-held control device for remote-controlled traffic lights easier to carry, a connecting portion 10 can be provided on the back of the housing 2 (the back of the housing 2 is a surface opposite to the front of the housing 2). Of course, the connection part 10 can also be arranged on other surfaces, or be arranged at the junction of two surfaces.

Specifically, when the connecting portion 10 is a belt card, it can be conveniently carried by a user who uses a belt, so as to be fixed on the belt. When the connecting part 10 is a detachable fixing belt, the user can choose to use one end of the detachable fixing belt to be fixed to the housing 2 and the other end to be fixed to the user according to needs. When the connecting part 10 is a fixed suction cup, the suction cup at one end can be used to suck the housing 2, and the suction cup at the other end can suck the user. Of course, only one end has a suction cup, and the other end can be fixed by other methods.

Furthermore, the outdoor handheld control device for remote-controlled traffic lights provided by the utility model also includes a semi-external antenna 6, which is electrically connected to the control chip.

The traditional external antenna has a strong ability to receive signals, which can make the remote wireless signal undistorted and ensure the quality of the signal, but at the same time, because the antenna is exposed to the outside world, the protection of the antenna is very weak. When it is installed inside the casing 2, the ability of the antenna to receive signals will decrease, resulting in signal distortion or failure to read.

Thus, a semi-external antenna 6 can be used to solve this problem. That is, a part of the antenna is located outside the housing 2 and a part is located inside the housing 2 . Therefore, both the protection of the antenna and the ability of the antenna to receive signals are guaranteed. Certainly, a protective layer and the like may also be provided outside the antenna to further protect the antenna.

Specifically, a group of function keys is also provided on the side of the housing 2, and the group of function keys includes a protruding key 8 and a concave key 7. When the protruding key 8 is not stressed, the top surface of the protruding key 8 protrudes from the housing 2 When the recessed key 7 is not stressed, the top surface of the recessed key 7 sinks into the outer surface of the housing 2, and both the raised key 8 and the recessed key 7 are electrically connected to the control chip.

The keys in the function input area can be in the form of interlaced arrangement of raised keys 8 and recessed keys 7. Since the feel of the raised keys 8 and the recessed keys 7 is very different, it is ensured that the keys in the function input area cannot be seen intuitively. Different keys can still be effectively recognized when the key is pressed.

Specifically, the raised keys 8 and recessed keys 7 provided on the surface of the shell can further improve the upper surface of the key accordingly, for example, the upper surface of the key can be set in the form of upward convex and downward concave. Specifically, the upper surfaces of the raised keys 8 are concave downwards, and the upper surfaces of the recessed keys 7 are convex upwards; or, when the raised keys 8 and the recessed keys 7 in the function key group are arranged When forming a row, the upper surfaces of the keys at both ends are concave downwards, and the upper surfaces of the other keys are convex upwards.

For another example, the keys in the function key group can be that the upper surface of the raised key 8 is provided with a protrusion, and the upper surface of the recessed key 7 has no protrusion, and when the raised key 8 and the recessed key 7 are arranged in the same row , then it may be that the raised keys 8 of this row gradually rise from one end to the other end, and along with the rise, the number of small protrusions on the upper surface of the raised keys 8 may increase or decrease.

It is also possible to change the direction of the keys in the function key group, so that the raised keys 8 are arranged towards different directions (that is, the raised keys 8 are columnar, and the height difference between the top surface and the bottom surface of each columnar raised key 8 is uniform. Same, the bottom surfaces of the plurality of columnar raised keys 8 are all on the same straight line, but the top surfaces of the plurality of columnar raised keys 8 are no longer on the same straight line), so that the raised keys 8 can be more effectively identified .

Specifically, the outdoor handheld control device for remote control traffic lights provided by the utility model also includes a button indicator light group arranged on the housing 2, the button indicator light group is electrically connected with the control chip, and is controlled according to different working states. glow.

The function of the button indicator light group can be used to give feedback to the user after the raised key 8 or the sunken key 7 is correctly operated (that is, after the control chip successfully obtains the electrical signal sent by the raised key 8 or the sunken key 7). , so that the user can know that the operation has been completed.

Of course, in order to make the user know more clearly which button sends the signal to be controlled by the chip, it may be that a plurality of indicator lights are arranged in the button indicator group, and one indicator light corresponds to a button, so that a certain button When a button is pressed, the indicator light associated with the button will light up, and the same indicator light will not light up after different buttons are pressed.

In addition to using a plurality of indicator lights to emit light, it is also possible to use indicator lights of different colors to emit light (the indicator light of each color corresponds to a button, that is, the indicator light and the button are in a one-to-one correspondence) to further enable the user to It is clear which button sends the signal and is received by the control chip.

Further, the key indicator light group includes lights with different luminous colors controlled by the CPU, which indicate different working states through different combinations of colors and luminous rhythms

Specifically, the recessed key 7 may be the most important key in an outdoor hand-held control device for remote control of traffic lights such as power supply, automatic return, menu setting, and function confirmation, so it is necessary to ensure that these keys will not be misoperated. And the probability of misoperation can be further reduced by setting the control chip.

Further, in the outdoor handheld control device for remote control traffic lights provided by the present invention, the control chip also includes an instruction generation module 103, which is electrically connected to the signal identification module, and the signal identification module includes a first identification unit 101 and The second identification unit 102, the first identification unit 101 is electrically connected with the number input button 9, the light color input button and other buttons except the confirmation key, and the second identification unit 102 is electrically connected with the confirmation key;

The instruction generating module 103 is used to obtain the instruction signal generated by the first identification unit 101 (the signal is generated after the first identification unit 101 receives the electric signal sent by the key connected to it) and the second identification unit 102 After the generated confirmation signal (the signal is generated after the second identification unit 102 receives the electrical signal sent by the confirmation key connected to it), an action signal is generated.

That is, in order to reduce the probability of misoperation, the instruction generation module 103 will only execute the corresponding action after receiving all the signals from the first identification unit 101 and the second identification unit 102 . That is, after the first identification unit 101 receives the instruction of the number input button 9, it does not directly generate the corresponding instruction, but needs to receive the electric signal of the confirmation key sent by the second identification unit 102 before it takes action. .

When in use, the user may press some buttons by mistake due to misoperation (such as putting an outdoor handheld control device for remote control traffic lights in his pocket, or other positions, due to vibration), which will cause the digital input button to be pressed. 9 will input a certain number of instructions, but in fact, these input instructions should have no effect, that is, they should not play a role. Therefore, only after the second recognition unit also works, the instruction generation module Work, and then generate action signals, thereby reducing the probability of misoperation.

Specifically, the confirmation key can be the recessed key 7, thereby further ensuring that the other keys will not affect the actual control even if they are misoperated.

In order to further play a role in identification, corresponding number protrusions can be provided on the top surface of the number input keys, so that users can effectively identify them.

It should be noted that the handheld device provided by this application is fully waterproof. By adding a waterproof device (rubber ring) between the upper and lower casings, and sealing between the transparent window of the display and the antenna and the casing, the casing can be waterproofed. Because it needs to be charged, the charging port rubber plug is designed. The main purpose of this charging rubber plug is also for waterproofing.

The above is only a specific embodiment of the present utility model, but the scope of protection of the present utility model is not limited thereto. Anyone familiar with the technical field can easily think of changes or changes within the technical scope disclosed by the utility model Replacement should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims.
