Embodiment 1 FIG.
FIG. 1 is a block diagram showing a configuration of a lighting control system 10 according to the present embodiment.

  In FIG. 1, the illumination control system 10 includes a controller 11, a communication unit 12, an illumination device 13, a human sensor 14, an illuminance sensor 15, a wall switch 16, a wireless remote controller 17, and a setting device 18.

  The controller 11 is an example of a lighting control device. The lighting device 13 blinks (turns on / off) according to the operation of the wall switch 16, the detection state of the human sensor 14, the illuminance value monitored by the illuminance sensor 15, and the like. Control the dimming state.

  The communication unit 12 performs wireless communication or wired communication with the controller 11. This communication is called upper communication. The communication unit 12 performs two-wire serial communication (bidirectional communication) via the lighting device 13, the human sensor 14, the illuminance sensor 15, the wall switch 16, and the signal line. This communication is called subordinate communication. The communication unit 12 has a gateway function between upper communication and lower communication. Specifically, the communication unit 12 converts a signal related to data setting, monitoring instruction, and illumination control (lighting, turning off, dimming, etc.) received from the controller 11 by wireless communication or wired communication into a two-wire wired serial signal. The individual address which becomes a serial number is previously allocated to each illumination device 13, the human sensor 14, the illuminance sensor 15, and the wall switch 16, and data setting, monitoring instruction, and illumination control are performed individually.

  The controller 11 and the communication unit 12 may be integrated so that the controller 11 communicates directly with the lighting device 13, the human sensor 14, the illuminance sensor 15, and the wall switch 16. Communication between the communication unit 12 (or the controller 11 integrated with the communication unit 12) and the lighting device 13, the human sensor 14, the illuminance sensor 15, and the wall switch 16 is performed by any communication method other than wired serial communication. You may go.

  As shown in FIG. 1, the lighting device 13, the human sensor 14, the illuminance sensor 15, and the wall switch 16 may be connected to a single communication unit 12, or may be connected to a single communication unit 12. A plurality of devices (for example, lighting device 13) may be connected to 12, or may be connected to one communication unit 12 in any other combination. That is, the overall configuration of the lighting control system 10 is determined according to the aspect of the lighting system to be constructed.

  The illuminating device 13 is an instrument including an LED, a fluorescent lamp, or another light source, and a lighting circuit that turns on the light source. The lighting device 13 turns on or off the light source or changes the brightness (output) of the light source according to a signal (signal related to lighting control) transmitted from the controller 11 via the communication unit 12.

  The human sensor 14 detects the presence / absence of a person in a specific area (detection area) in accordance with a signal (a signal related to data setting or a monitoring instruction) transmitted from the controller 11 via the communication unit 12. Then, the detection information indicating the result is notified to the controller 11.

  The illuminance sensor 15 measures the illuminance (for example, the illuminance on the desk surface) in a specific area around the signal (signal related to data setting or monitoring instruction) transmitted from the controller 11 via the communication unit 12. The illuminance information indicating the result is notified to the controller 11.

  The wall switch 16 is operated by a user (for example, a button is pressed) for lighting control and dimming control of the light source of the lighting device 13. When the wall switch 16 is operated by the user, the wall switch 16 notifies the controller 11 of operation information indicating the state (for example, button press).

  The wireless remote controller 17 performs wireless communication with the controller 11 and the communication unit 12, lighting control and dimming control of the light source of the lighting device 13, and status monitoring and data of each device including the controller 11 and the communication unit 12 by a user's remote operation. Set up.

  The setting device 18 is, for example, a personal computer, performs wireless communication or wired communication with the controller 11 and the communication unit 12, and controls each of the lighting device 13 lighting control and dimming control from the screen, including the controller 11 and the communication unit 12. Perform device status monitoring and data settings.

  FIG. 2 is a block diagram showing the configuration of the illumination device 13 (in the case of LED) connected to the communication unit 12.

  In FIG. 2, the illumination device 13 includes a control unit 21, an LED power supply device 22, and an LED light source 23.

  The control unit 21 performs wired communication with the communication unit 12, and outputs a PWM (pulse width modulation) dimming signal to the LED power supply device 22 based on a command from the communication unit 12. The LED power supply device 22 turns on or off the LED light source 23 or performs dimming according to the PWM dimming signal from the control unit 21. The LED light source 23 is a light source on which an LED chip is mounted, and is driven by the LED power supply device 22.

  For example, when a signal for changing the dimming rate is transmitted from the communication unit 12 to the control unit 21, the control unit 21 analyzes the received signal (data) and outputs the PWM control output to the LED power supply device 22. The brightness of the LED light source 23 is changed by changing the optical signal.

  FIG. 3 is a block diagram showing a configuration of the illumination device 13 (in the case of a fluorescent lamp) connected to the communication unit 12.

  In FIG. 3, the lighting device 13 includes a control unit 21, an inverter 24, and a fluorescent lamp 25.

  The control unit 21 performs wired communication with the communication unit 12 and outputs a PWM dimming signal to the inverter 24 based on a command from the communication unit 12. The inverter 24 turns on or off the fluorescent lamp 25 or performs dimming according to the PWM dimming signal from the control unit 21. The fluorescent lamp 25 is driven by the inverter 24.

  For example, when a signal for changing the dimming rate is transmitted from the communication unit 12 to the control unit 21, the control unit 21 analyzes the received signal (data) and outputs the PWM dimming signal output to the inverter 24. Is changed, the brightness of the fluorescent lamp 25 is changed.

  FIG. 4 is a block diagram showing the configuration of the controller 11.

  In FIG. 4, the controller 11 includes a setting unit 31, a storage unit 32, and an illumination control unit 33.

  The setting unit 31 assigns the human sensor 14 and the lighting device 13 connected to the controller 11 directly or via the communication unit 12 to an entrance / exit management group or a normal group. Specifically, the setting unit 31 includes an entrance / exit management group to which the human sensor 14 installed near the entrance of the room belongs, and a normal to which the human sensor 14 and the lighting device 13 installed at other positions in the room belong. Set up a group. The setting unit 31 may set only one entrance / exit management group. However, in the present embodiment, a plurality of entrance / exit in which the human sensors 14 belonging to each group are installed near different entrances / exits in the room. It is assumed that a management group (for example, entry / exit management groups 1 and 2 described later) is set. In addition, the setting unit 31 may set only one normal group, but in the present embodiment, a plurality of normal groups (for example, a normal group described later) having different positions of the human sensor 14 belonging to each of the normal groups may be set. 1 to 6) are set. In addition, the setting part 31 may set the entrance / exit management group to which the illuminating device 13 installed in the vicinity of the entrance / exit belongs to the human sensor 14 installed in the vicinity of the entrance / exit of the room as the entrance / exit management group.

  For each entry / exit management group set by the setting unit 31, the storage unit 32 includes an identifier (for example, a number) of the entry / exit management group and an identifier (for example, a number) of the human sensor 14 of the entry / exit management group. Address, time at which the human sensor 14 last detected a human body, detection state of a human body in the entry / exit management group (for example, a current detection state within a predetermined time since the human sensor 14 last detected a human body, Other than that is set to the absence state or the absence detection state) and the like are stored in association with each other. In addition, the storage unit 32 includes, for each normal group set by the setting unit 31, an identifier (for example, a number) of the normal group, an identifier (for example, a number) or an address of the human sensor 14 of the normal group, an address, The identifier (eg, number) and address of the lighting device 13 of the normal group, such as the time when the sensor 14 last detected a human body, the detection status of the human body of the normal group, and the lighting state of the lighting device 13 are stored in association with each other. To do.

  The lighting control unit 33 determines whether the human sensor 14 of the entrance / exit management group set by the setting unit 31 detects the presence of the human body, and the human sensor 14 of the normal group set by the setting unit 31 Which lighting device 13 is lit or extinguished while referring to the information stored in the storage unit 32 according to whether or not the presence is detected, the timing at which each human sensor 14 detects the presence of a human body, etc. And the lighting control of each lighting device 13 is performed. In the present embodiment, when the human group sensor 14 of the normal group set by the setting unit 31 detects the presence of a human body, the illumination control unit 33 within a predetermined time before that (for example, within 1 minute) ( If the human sensor 14 of the entrance / exit management group set by the setting unit 31 detects the presence of a human body, the lighting device 13 of the normal group is turned on. Let As a result, when the human sensor 14 of the normal group detects a change in the surrounding environment other than the human body (change in infrared, magnetic field, capacitance, reflected wave of ultrasonic wave, reflected wave of electromagnetic wave, etc.), that is, erroneous detection In spite of the fact that the person has not entered the room (the person sensor 14 of the entry / exit management group should have detected the presence of the human body immediately before or at the same time) The malfunction of lighting the lighting device 13 of the normal group is less likely to occur.

  The storage unit 32 is, for example, a memory (for example, RAM, ROM, flash memory). Although not shown, the controller 11 includes a processor such as a CPU that executes a program, for example. The processor is connected to the storage unit 32 via the bus and controls each unit. The storage unit 32 stores various data and signals other than the identifiers and addresses described above. Data and signals are transmitted by buses, signal lines, cables and other transmission media. The setting unit 31 and the illumination control unit 33 may be realized by firmware stored in the ROM, or only software, or only hardware such as an element, a device, a board, and wiring, or software and hardware. It may be realized in combination with hardware, or in combination with firmware. Firmware and software are stored in the storage unit 32 as programs. This program is read by the processor and executed by the processor.

  FIG. 5 is a device layout diagram of the illumination control system 10. FIG. 5 shows an arrangement example of the human sensor 14 of the entrance / exit management group, the human sensor 14 of the normal group, and the lighting device 13 when the lighting device 13 is not included in the entrance / exit management group.

  In the example of FIG. 5, the room is divided into six blocks, which are normally grouped 1 to 6, and four lighting devices 13 and one human sensor 14 are assigned to each normal group. In addition to the normal groups 1 to 6 in the room, the human sensors 14 installed near the two entrances of the room are set as the entrance / exit management groups 1 and 2, respectively.

  FIG. 6 is a flowchart showing the operation of the controller 11 when the human sensor 14 in the normal group detects the presence of a human body.

  In FIG. 6, when the presence detection of the human sensor 14 of the normal group is detected (“occurrence” in step S11), the controller 11 confirms the detection state of the entry / exit management group (step S12). If the entrance / exit management group is in the presence detection state (“presence detection state” in step S12), the controller 11 validates the presence detection of the normal group (step S13) and lights the lighting device 13 of the normal group (step S13). Step S14). If the entrance / exit management group is absent (“absent state” in step S12), the controller 11 invalidates the presence detection of the normal group and does not operate until the next presence detection by the human sensor 14 occurs.

  Here, the detailed operation of the controller 11 when the entrance / exit management group and the normal group are set as in the example of FIG. 5 will be described.

  For example, when a predetermined time (for example, 1 minute) has elapsed since the human sensors 14 of all the normal groups 1 to 6 set by the setting unit 31 have finally detected the presence of a human body (that is, When all the normal groups 1 to 6 are absent), the lighting devices 13 of all the normal groups 1 to 6 are turned off. In this state, when the human sensor 14 of the normal group 1 (example of one normal group) detects the presence of the human body among the normal groups 1 to 6 (that is, the normal group 1 is in the presence detection state). ("Occurrence" in step S11). In this case, the illumination control unit 33 detects that the human sensor 14 of the entrance / exit management group 1 or 2 set by the setting unit 31 is within the predetermined time (for example, within 1 minute) before that. It is determined whether or not presence is detected (step S12). That is, the illumination control unit 33 determines whether any of the entry / exit management groups 1 and 2 is in the presence detection state.

  If any of the entrance / exit management groups 1 and 2 is in the presence detection state, the illumination control unit 33 turns on the illumination device 13 of the normal group 1 (steps S13 and S14). If all of the entrance / exit management groups 1 and 2 are absent, the illumination control unit 33 keeps the illumination devices 13 of the normal group 1 off (returns to step S11).

  As described above, in the present embodiment, when all of the normal group and the entrance / exit management group are in the absence detection state, the presence detection is invalidated even when the presence sensor 14 of the normal group detects the presence, The lighting operation of the lighting device 13 normally assigned to the group is not performed. On the other hand, when the presence / absence management group is already in the presence detection state when the presence sensor 14 of the normal group is detected, the presence detection of the normal group is validated and the lighting device previously assigned to the same normal group 13 lighting operations are performed.

  By this function, the human sensor 14 is not operating the human body, that is, popcorn noise generated from the human sensor 14 itself, noise received from the transmission line, radio noise received from the space, airflow change due to air conditioning, temperature, etc. Preventing the malfunction of the lighting device 13 performing an unnecessary lighting operation when a presence is detected in the absence of a person due to a change, movement of an object other than a small animal or a human body, and an operation of an electric / electronic device serving as a heat source. Can do. Since a person cannot enter without detecting the presence sensor 14 of the entrance / exit management group set in the vicinity of the entrance / exit of the room, the entrance / exit management is effective to enable the presence detection of the first normal group. On the condition that the group is in the presence detection state, if the presence sensor 14 of the first normal group detects the presence in spite of the absence of the entry / exit management group, it is a false detection. Judgment and invalidate presence detection.

  Below, the modification of this Embodiment is demonstrated.

  FIG. 7 is a device layout diagram of the illumination control system 10. FIG. 7 shows an arrangement example of the human sensor 14 of the entrance / exit management group, the human sensor 14 of the normal group, and the lighting device 13 when the lighting device 13 is included in the entrance / exit management group.

  In the example of FIG. 7, normal groups 1 to 6 are set as in the example of FIG. In addition, human sensors 14 installed near the two entrances of the room are set as entrance / exit management groups 1 and 2, respectively. In addition to the human sensor 14, two illumination devices 13 are assigned to the entrance / exit management group 1.

  FIG. 8 is a flowchart showing the operation of the controller 11 when the human sensor 14 of the entrance / exit management group detects the presence of a human body.

  In FIG. 8, when the presence sensor 14 of the entrance / exit management group is detected ("occurrence" in step S21), the controller 11 unconditionally validates the presence detection of the entrance / exit management group (step S22). The lighting device 13 of the entrance / exit management group is turned on (step S23).

  Here, the detailed operation of the controller 11 when the entrance / exit management group and the normal group are set as in the example of FIG. 7 will be described.

  The operation when the human sensor 14 of any of the normal groups 1 to 6 detects the presence of a human body (that is, any of the normal groups 1 to 6 enters the presence detection state). Thus, the operation is the same as when the entry / exit management group and the normal group are set.

  For example, when a predetermined time (for example, 1 minute) has elapsed since the human sensor 14 of the entrance / exit management group 1 set by the setting unit 31 last detected the presence of a human body (that is, entry / exit) When the management group 1 is absent), the lighting device 13 of the entrance / exit management group 1 is turned off. In this state, it is assumed that the human sensor 14 of the entrance / exit management group 1 detects the presence of a human body (that is, the entrance / exit management group 1 enters the presence detection state) ("occurrence" in step S21). In this case, the lighting control unit 33 turns on the lighting device 13 of the entrance / exit management group 1 (steps S22 and S23).

  As described above, even in the entrance / exit management group, for example, the lighting device 13 may be turned on when the presence sensor 14 detects the presence, and may be turned off when the absence is detected.

  In the present embodiment, a single or a plurality of lighting devices 13 and human sensors 14 can be assigned to each group, and when a plurality of human sensors 14 are assigned, the controller 11 is included in the group. Even when only one human sensor 14 is detected, it is determined that the group is in the presence detection state. The controller 11 determines that the group is in an absence state only when all the human sensors 14 detect the absence. Further, by assigning the above-described illuminance sensor 15 and wall switch 16 to each group, it is possible to control in combination.

  On the other hand, for the entrance / exit management group, the controller 11 enables the presence detection when the presence sensor 14 of the entrance / exit management group detects the presence even if all the groups are in the absence detection state. If there is the lighting device 13 assigned to the entrance / exit management group, the lighting operation is executed. In other words, the presence / absence management group is enabled to detect presence regardless of the detection state of other groups.

  When the presence of the human sensor 14 in the normal group is detected (“occurrence” in step S11), the controller 11 manages the entry / exit if the lighting device 13 in the entry / exit management group is lit at that time. Regardless of the detection state of the group, the presence detection of the normal group may be validated (step S13), and the lighting device 13 of the normal group may be turned on (step S14). That is, when the lighting device 13 of the entrance / exit management group is turned on, the lighting control unit 33 may consider that the human sensor 14 of the entrance / exit management group detects the presence of a human body.

  As described above, in the present embodiment, the illumination control system 10 includes a plurality of illumination devices 13, a controller 11 that transmits a command signal for performing lighting control and function setting of the illumination devices 13, and the illumination device 13. A plurality of communication units 12 that receive command signals transmitted from the controller 11 and that are connected via signal lines and output to the lighting device 13 via the signal lines, and lighting devices that are connected to and associated with the communication units 12 via signal lines In order to control 13 blinking, a wall switch 16 that transmits operation information to the controller 11, an illuminance sensor 15 that detects illuminance values in a corresponding range and transmits illuminance information to the controller 11, and a person enters the detection area It consists of a human sensor 14 that detects that the controller 11 has detected and transmits detection information of the controller 11. There are two types of groups: a single or multiple entrance / exit management group installed near the entrance / exit of the area where the lighting device 13 is installed, and a single or multiple normal group installed other than the entrance / exit. Yes. When all the normal groups are absent, the controller 11 is in a state where any one of the entry / exit management groups is in the presence detection state (or the lighting device 13 is lit in any one of the entry / exit management groups Only when a normal group is present. As a result, the probability of unnecessary lighting of the illuminating device 13 can be reduced even when the human sensor 14 erroneously detects the noise due to noise or the like.

Embodiment 2. FIG.
In the present embodiment, differences from the first embodiment will be mainly described.

  FIG. 9 is a flowchart showing the operation of the controller 11 when the human sensor 14 of the normal group detects the presence of a human body.

  In FIG. 9, when the presence detection of the human sensor 14 of the normal group is detected (“occurrence” in step S31), the controller 11 confirms the detection state of the entry / exit management group (step S32). If the entrance / exit management group is in the presence detection state (“presence detection state” in step S32), the controller 11 validates the presence detection of the normal group (step S34) and lights the lighting device 13 of the normal group (step S34). Step S35). Even when the entry / exit management group is absent (“absent state” in step S32), when there is at least one presence detection group in another normal group (“presence detected state” in step S33), The controller 11 validates the presence detection of the normal group (step S34), and turns on the lighting device 13 of the normal group (step S35). If all other normal groups are absent (“absent state” in step S33), the controller 11 invalidates the presence detection of the normal group and does not operate until the next presence detection by the human sensor 14 occurs.

  Here, the detailed operation of the controller 11 when the entrance / exit management group and the normal group are set as in the example of FIG. 5 will be described.

  For example, when a predetermined time (for example, 1 minute) has elapsed since the human sensor 14 of the normal group 1 set by the setting unit 31 last detected the presence of a human body (that is, the normal group 1 In the absence state), the illumination device 13 of the normal group 1 is turned off. In this state, it is assumed that the human sensor 14 of the normal group 1 detects the presence of a human body (that is, the normal group 1 is in the presence detection state) ("occurrence" in step S31). In this case, the illumination control unit 33 detects that the human sensor 14 of the entrance / exit management group 1 or 2 set by the setting unit 31 is within the predetermined time (for example, within 1 minute) before that. It is determined whether or not presence is detected (step S32). That is, the illumination control unit 33 determines whether any of the entry / exit management groups 1 and 2 is in the presence detection state.

  If any of the entrance / exit management groups 1 and 2 is in the presence detection state, the illumination control unit 33 turns on the illumination device 13 of the normal group 1 (steps S34 and S35). When all of the entrance / exit management groups 1 and 2 are in the absence state, the lighting control unit 33 is one of the normal groups 2 to 6 (others) within a predetermined time (for example, within 1 minute) before that. It is determined whether or not the human sensor 14 of the example of the normal group detects the presence of a human body (step S33). That is, the illumination control unit 33 determines whether any of the normal groups 2 to 6 is in the presence detection state.

  Even if all of the entrance / exit management groups 1 and 2 are in the absence state, if any of the normal groups 2 to 6 is in the presence detection state, the lighting control unit 33 switches the lighting device 13 in the normal group 1. Lights up (steps S34 and S35). If all of the entrance / exit management groups 1 and 2 and the normal groups 2 to 6 are absent, the lighting control unit 33 keeps the lighting devices 13 of the normal group 1 off (return to step S31). .

  The controller 11 detects that the presence sensor 14 of the normal group is present ("occurrence" in step S31), and if the entrance / exit management group is absent ("absent state" in step S32). ), If the lighting device 13 of another normal group is turned on at that time, the presence detection of the normal group is validated regardless of the detection state of the other normal group (step S34), and the lighting device of the normal group 13 may be lit (step S35). That is, the illumination control unit 33 may consider that the human sensor 14 of the other normal group detects the presence of the human body when the illumination device 13 of the other normal group is turned on.

  Further, the controller 11 detects that the presence sensor 14 of the normal group is present ("occurrence" in step S31), and if the entry / exit management group is absent ("absent state" in step S32). ) If any one of the other normal groups is in the detection state (“presence detection state” in step S33), the presence detection of the normal group is enabled (step S34), and the lighting device 13 of the normal group is turned on. (Step S35) At this time, the illumination devices 13 of other normal groups that are in the detection state may also be turned on (if they are turned off).

  As described above, in the present embodiment, when any one of the normal groups is in the presence detection state (or when the lighting device 13 is in the lighting state in any one of the normal groups). Even if all the entrance / exit management groups are absent, the presence detection of other normal groups is enabled.

  With this function, even if there are people in the range of the normal group in the room and work is performed for a long time, even if there are no people near the entrance / exit management group, the person moves between the normal groups and newly When another normal group is detected, the illumination device 13 can be turned on as effective.

Embodiment 3 FIG.
In the present embodiment, differences from the first embodiment will be mainly described.

  FIG. 10 is a flowchart showing the operation of the controller 11 when the human sensor 14 in the normal group detects the presence of a human body.

  In FIG. 10, when the presence detection of the human sensor 14 in the normal group is detected (“occurrence” in step S41), the controller 11 confirms the detection state of the entry / exit management group (step S42). If the entry / exit management group is in the presence detection state (“presence detection state” in step S42), the controller 11 validates the presence detection of the normal group (step S44) and lights the lighting device 13 of the normal group (step S44). Step S45). Even when the entrance / exit management group is absent (“absent state” in step S42), the normal group adjacent to the normal group to which the human sensor 14 detected this time is present is in the presence detected state (in step S43). The controller 11 validates the presence detection of the normal group to which the presence sensor 14 detected this time is present (step S44), and turns on the lighting device 13 of the normal group (step S45). If the adjacent normal group is absent (“absent state” in step S43), the controller 11 invalidates the presence detection of the normal group to which the human sensor 14 that has been detected this time belongs, and then uses the human sensor 14. Does not work until presence detection occurs.

  Note that setting information indicating which normal groups are adjacent to each other is written in advance in the storage unit 32 of the controller 11 from the wireless remote controller 17 or the setting device 18.

  Here, the detailed operation of the controller 11 when the entrance / exit management group and the normal group are set as in the example of FIG. 5 will be described.

  For example, when a predetermined time (for example, 1 minute) has elapsed since the human sensor 14 of the normal group 1 set by the setting unit 31 last detected the presence of a human body (that is, the normal group 1 In the absence state), the illumination device 13 of the normal group 1 is turned off. In this state, it is assumed that the human sensor 14 of the normal group 1 detects the presence of a human body (that is, the normal group 1 is in the presence detection state) (“occurrence” in step S41). In this case, the illumination control unit 33 detects that the human sensor 14 of the entrance / exit management group 1 or 2 set by the setting unit 31 is within the predetermined time (for example, within 1 minute) before that. It is determined whether or not presence is detected (step S42). That is, the illumination control unit 33 determines whether any of the entry / exit management groups 1 and 2 is in the presence detection state.

  If any of the entrance / exit management groups 1 and 2 is in the presence detection state, the illumination control unit 33 turns on the illumination device 13 of the normal group 1 (steps S44 and S45). When all of the entrance / exit management groups 1 and 2 are in the absence state, the lighting control unit 33 makes the normal group 2 adjacent to the normal group 1 within a predetermined time (for example, within 1 minute) before that. It is determined whether any one of the human sensors 14 (which may further include the normal group 5) detects the presence of a human body (step S43). That is, the illumination control unit 33 determines whether any of the normal groups 2 and 4 is in the presence detection state.

  Even if all of the entrance / exit management groups 1 and 2 are in the absence state, if one of the normal groups 2 and 4 is in the presence detection state, the lighting control unit 33 switches the lighting device 13 in the normal group 1. Lights up (steps S44, S45). If all of the entrance / exit management groups 1 and 2 and the normal groups 2 and 4 are absent, the lighting control unit 33 keeps the lighting devices 13 of the normal group 1 off (return to step S41). .

  The controller 11 detects that the presence sensor 14 of the normal group is present ("occurrence" in step S41), and if the entry / exit management group is absent ("absent state" in step S42). ) If the lighting device 13 of the adjacent normal group is currently lit at that time, the presence detection of the normal group is validated regardless of the detection state of the adjacent normal group (step S44), and the lighting device of the normal group 13 may be lit (step S45). That is, the illumination control unit 33 may consider that the human sensor 14 of the other normal group detects the presence of the human body when the illumination device 13 of the other normal group that is adjacent is turned on. .

  Further, the controller 11 detects that the presence sensor 14 of the normal group is present ("occurrence" in step S41) and if the entrance / exit management group is absent ("absent state" in step S42). If the adjacent normal group is in the detection state (“presence detection state” in step S43), the normal group presence detection is enabled (step S44), and the lighting device 13 of the normal group is turned on (step S45). At this time, the lighting devices 13 in the adjacent normal group that are in the detection state may also be turned on together (if they are turned off).

  As described above, in this embodiment, when all the normal groups are absent, even if the entry / exit management group is not in the presence detection state, the groups adjacent to each other within an arbitrary time within the normal group Is continuously detected (or the lighting device 13 is in a lighting state in any one of the adjacent normal groups), the normal group presence detection is enabled.

  With this function, even if there are people in the normal group range in the room and work for a long time, even if there are no people in the vicinity of the entrance / exit management group, people move between the normal groups and are adjacent to each other. Only when the normal group is detected, the current normal group can be validated and the lighting device 13 can be turned on.

Embodiment 4 FIG.
In the present embodiment, differences from the first embodiment will be mainly described.

  FIG. 11 is a flowchart showing the operation of the controller 11 when the human sensor 14 of the normal group detects the presence of a human body.

  In FIG. 11, when the presence detection of the human sensor 14 in the normal group is detected (“occurrence” in step S51), the controller 11 confirms the detection state of the entry / exit management group (step S52). If the entrance / exit management group is in the presence detection state (“presence detection state” in step S52), the controller 11 validates the presence detection of the normal group (step S54) and lights the lighting device 13 of the normal group (step S54). Step S55). Even when the entrance / exit management group is absent (“absent state” in step S52), the presence sensor 14 is detected within the arbitrary immediately preceding grace period in the normal group to which the presence sensor 14 detected this time is present. If there is a recorded history ("history exists" in step S53), the controller 11 validates the presence detection of the normal group to which the human sensor 14 detected this time is present (step S54), and activates the lighting device 13 of the normal group. Turn on (step S55). When there is no history of presence detection within an arbitrary grace period (“No history” in step S53), the controller 11 invalidates the presence detection of the normal group to which the presence sensor 14 detected this time exists, It does not operate until presence detection by the sense sensor 14 occurs.

  The grace period can be arbitrarily set (however, set longer than the predetermined time described above), and is written in advance in the storage unit 32 of the controller 11 from the wireless remote controller 17 or the setting device 18.

  Here, the detailed operation of the controller 11 when the entrance / exit management group and the normal group are set as in the example of FIG. 5 will be described.

  For example, when a predetermined time (for example, 1 minute) has elapsed since the human sensors 14 of all the normal groups 1 to 6 set by the setting unit 31 have finally detected the presence of a human body (that is, When all the normal groups 1 to 6 are absent), the lighting devices 13 of all the normal groups 1 to 6 are turned off. In this state, it is assumed that the human sensor 14 of the normal group 1 detects the presence of a human body (that is, the normal group 1 is in the presence detection state) ("occurrence" in step S51). In this case, the illumination control unit 33 detects that the human sensor 14 of the entrance / exit management group 1 or 2 set by the setting unit 31 is within the predetermined time (for example, within 1 minute) before that. It is determined whether or not presence is detected (step S52). That is, the illumination control unit 33 determines whether any of the entry / exit management groups 1 and 2 is in the presence detection state.

  If any of the entrance / exit management groups 1 and 2 is in the presence detection state, the illumination control unit 33 turns on the illumination device 13 of the normal group 1 (steps S54 and S55). When all of the entrance / exit management groups 1 and 2 are in the absence state, the lighting control unit 33 detects the human sensor 14 of the normal group 1 within a previously designated time (for example, within 5 minutes). It is determined whether or not the presence of a human body has been detected (step S53). That is, the illumination control unit 33 determines whether or not the grace period has elapsed since the human sensor 14 of the normal group 1 detected the presence of a human body last time.

  Even if all of the entrance / exit management groups 1 and 2 are absent, if the grace period has not elapsed since the human sensor 14 of the normal group 1 detected the presence of a human body last time, the lighting control unit 33 Turns on the lighting device 13 of the normal group 1 (steps S54 and S55). If all of the entrance / exit management groups 1 and 2 are in the absence state, and the grace period has elapsed since the human sensor 14 of the normal group 1 detected the presence of the human body last time, the lighting control unit 33 The lighting devices 13 of the normal group 1 are kept off (return to step S51).

  As described above, in this embodiment, when all normal groups are absent, the same group within an arbitrary time within the normal group even if the entry / exit management group is not in the presence detection state When the presence detection state is again entered, normal group presence detection is enabled.

  By this function, for example, when there is a person in the range of the normal group in the room and there is no person in the vicinity of the entrance / exit management group, the human sensor 14 does not operate for a certain period of time within the range of the normal group. When the lighting device 13 is turned off when the absence is detected, if the person is operating again on the spot within the preset grace period, the same human sensor 14 detects the presence again. The presence detection of the group becomes effective, and the lighting device 13 can be turned on.

Embodiment 5. FIG.
In the present embodiment, differences from the first embodiment will be mainly described.

  FIG. 12 is a flowchart showing the operation of the controller 11 when the human sensor 14 in the normal group detects the presence of a human body.

  In FIG. 12, when the presence detection of the human sensor 14 in the normal group is detected (“occurrence” in step S61), the controller 11 confirms the detection state of the entry / exit management group (step S62). If the entrance / exit management group is in the presence detection state (“presence detection state” in step S62), the controller 11 validates the presence detection of the normal group (step S64) and lights the lighting device 13 of the normal group (step S64). Step S65). Even when the entry / exit management group is absent (“absent state” in step S62), the last time when all groups were absent, the last detected absence was the normal group (step S63). The controller 11 validates the presence detection of the normal group to which the human sensor 14 detected this time is present (step S64), and turns on the lighting device 13 of the normal group (step S65). If the last time all the groups were absent, the last detected absence was the entrance / exit management group (“entrance / exit management group” in step S63), the controller 11 senses the presence detected this time. The presence detection of the normal group to which the sensor 14 belongs is invalidated, and the operation is not performed until the next presence detection by the human sensor 14 occurs.

  Here, the detailed operation of the controller 11 when the entrance / exit management group and the normal group are set as in the example of FIG. 5 will be described.

  For example, when a predetermined time (for example, 1 minute) has elapsed since the human sensors 14 of all the normal groups 1 to 6 set by the setting unit 31 have finally detected the presence of a human body (that is, When all the normal groups 1 to 6 are absent), the lighting devices 13 of all the normal groups 1 to 6 are turned off. In this state, it is assumed that the human sensor 14 of the normal group 1 detects the presence of a human body (that is, the normal group 1 is in the presence detection state) ("occurrence" in step S61). In this case, the illumination control unit 33 detects that the human sensor 14 of the entrance / exit management group 1 or 2 set by the setting unit 31 is within the predetermined time (for example, within 1 minute) before that. It is determined whether or not presence is detected (step S62). That is, the illumination control unit 33 determines whether any of the entry / exit management groups 1 and 2 is in the presence detection state.

  If any of the entrance / exit management groups 1 and 2 is in the presence detection state, the illumination control unit 33 turns on the illumination device 13 of the normal group 1 (steps S64 and S65). When all of the entrance / exit management groups 1 and 2 are in the absence state, the lighting control unit 33 determines which group of human sensors 14 the human sensor 14 that last detected the human body before that. Is determined (step S63).

  Even if all of the entrance / exit management groups 1 and 2 are in the absence state, if the human sensor 14 that lastly detected the presence of the human body is the human sensor 14 of any of the normal groups 1 to 6, lighting control is performed. The unit 33 turns on the lighting device 13 of the normal group 1 (steps S64 and S65). If all of the entrance / exit management groups 1 and 2 are in the absence state and the human sensor 14 that finally detected the presence of the human body is the human sensor 14 of any of the entrance / exit management groups 1 and 2, lighting is performed. The control unit 33 keeps the lighting devices 13 of the normal group 1 off (returns to step S61).

  As described above, in this embodiment, when all the normal groups are absent, if the last detected group out of all the groups is a normal group, the entrance / exit management group is in the presence detected state. Even if not, normal group presence detection is enabled.

  With this function, if it was the normal group that detected the absence at the end, it can be determined that the person is still present in the room, but the absence is detected due to a stoppage, etc. Can be determined that the person has exited the entrance / exit.

Embodiment 6 FIG.
In the present embodiment, differences from the first embodiment will be mainly described.

  In the present embodiment, a plurality of entrance / exit management groups and a plurality of normal groups are classified into a plurality of divided groups.

  FIG. 13 is a device layout diagram of the illumination control system 10. FIG. 13 shows a setting example of the division group in the example of FIG.

  In the example of FIG. 13, normal groups 1 and 4 are assigned as divided group 1, normal groups 2 and 5 are assigned as divided group 2, and normal groups 3 and 6 are assigned as divided group 3.

  In the first embodiment, the validity / invalidity of the presence detection of the normal group to which the human sensor 14 detected this time is present is determined based on the presence detection state of the normal group in the room according to each condition. In the embodiment, the range of the normal group to be determined is not limited to all the normal groups in the room, but only the normal groups belonging to the same divided group, so that unnecessary operations due to erroneous detection can be efficiently suppressed. In the second to fifth embodiments as well, it is possible to set a divided group and perform illumination control in units of divided groups (determine a group to turn on the lighting device 13) as in the present embodiment. That is, as shown in FIGS. 9 to 12, the divided group may be the target when the state of the normal group is viewed.

  Here, the detailed operation of the controller 11 when the entrance / exit management group and the normal group are set as in the example of FIG. 13 will be described with reference to FIG.

  For example, when a predetermined time (for example, 1 minute) has elapsed since the human sensors 14 of the normal groups 1 and 2 set by the setting unit 31 last detected the presence of a human body (that is, divided groups) When the normal groups 1 and 2 belonging to 1 are absent, the illumination devices 13 of the normal groups 1 and 2 are turned off. In this state, it is assumed that the human sensor 14 of the normal group 1 detects the presence of a human body (that is, the normal group 1 is in the presence detection state) ("occurrence" in step S11). In this case, the lighting control unit 33 enters / exits management group 1 belonging to the same divided group 1 as the normal group 1 out of the entrance / exit management groups 1 and 2 within a predetermined time before that (for example, within 1 minute). It is determined whether the human sensor 14 detects the presence of a human body (step S12). That is, the illumination control unit 33 determines whether the entrance / exit management group 1 is in the presence detection state.

  If the entrance / exit management group 1 is in the presence detection state, the lighting control unit 33 turns on the lighting device 13 of the normal group 1 (steps S13 and S14). If the entrance / exit management group 1 is absent, the illumination control unit 33 keeps the illumination devices 13 of the normal group 1 off (return to step S11).

  Below, the modification of this Embodiment is demonstrated.

  In this modification, the same normal group is allowed to belong to two or more divided groups so that adjacent normal groups belong to the same divided group, and the plurality of normal groups are classified into a plurality of divided groups.

  FIG. 14 is a device layout diagram of the illumination control system 10. FIG. 14 shows a setting example of the division group in the example of FIG.

  In the example of FIG. 14, normal groups 1, 2, 4, and 5 are assigned as divided group 1, and normal groups 2, 3, 5, and 6 are assigned as divided group 2.

  In this modified example, since the normal groups belonging to the adjacent split groups operate in association with each other, the normal groups located at the boundaries of the adjacent split groups are included in the respective split groups, and the setting range Are duplicates. Therefore, for example, when the normal group 2 is in the presence detection state, since the normal group 2 belongs to both the divided group 1 and the divided group 2, which of the entry / exit management groups 1 and 2 is in the presence detection state. Similarly, the presence detection of the normal group 2 can be made effective and the lighting device 13 can be turned on.
