Description

  The present invention relates to a dimming control system for controlling light to a dimming target space by turning on / off a lighting device or opening / closing a blind.

  Many dimming facilities (lighting equipment, blinds, etc.) are provided in facilities with large spaces such as large conference rooms and offices. In such a facility, if it is possible to appropriately control the light to the necessary zone when necessary, it is possible to facilitate the work of the occupant and at the same time reduce the energy and utility costs required for dimming. Can be planned.

  In consideration of such circumstances, conventionally, a dimming control system that automatically detects the presence or absence of a room occupant and the position of the occupant and performs appropriate dimming control has been considered.

  For example, in Patent Document 1, a human detection sensor that detects the presence / absence of a human body is provided in each of the lighting devices attached adjacent to the ceiling of the room, and the lighting device that detects a person at the closest distance is the brightest. It is shown that control is performed so that a lighting device that is turned on and turned on is darker than that, and a lighting device that has not detected a person is turned off.

  Patent Document 2 discloses a light control device that adjusts a blind slat angle and a blind length according to a human presence / absence pattern in a living space detected by a human body sensor. In this light control device, an optimal slat angle and blind length are inferred from human location information and number information detected by a human body sensor through learning using a neural network.

JP 2000-228290 A JP 7-293149 A

  However, in the technique disclosed in Patent Document 1 described above, a place where the occupant is present is brightly illuminated, and is relatively darkly illuminated in the vicinity thereof, but is not illuminated elsewhere. For example, when a meeting is held in the area and a person is present in order to use an overhead projector (OHP), it is not possible to cope with this.

  In the technique disclosed in Patent Document 2, the blind slat angle and the blind length are adjusted to the optimum values according to the human presence / absence pattern in the living space by learning using a neural network. For example, in the case where a special case occurs in which it is desired to darken a conference using OHP in the living space, this cannot be dealt with.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a dimming control system capable of achieving both automatic dimming control and the occupants' desires. It is in.

  In order to achieve such an object, the present invention provides a human detection unit that detects whether or not a person is present in the dimming target space, and light to the dimming target space based on a detection result of the human detection unit. And a control means for controlling the control device, the control device provided in the light control target space, and the control means for the request from the occupants in the light control target space input through the control device When the manual operation request is received as a request from the occupant via the controller, the control of the light to the light control target space based on the detection result of the human detection unit is interrupted. If the automatic control request is received as a request from the occupant via the controller, the light to the dimming target space according to the manual operation request is controlled. Control to the dimming space It is provided with a means for returning the control based control of light on the detection result of the human detection means.

  According to this invention, normally, the light to the light control target space is controlled (automatically controlled) based on the detection result of the human detection means. For example, when a person enters a dimming target space where no one is present, the lighting is automatically turned on or the blind is opened. In the state where the dimming target space is brightened by this automatic control, when the occupant operates the operating device and sends a manual operation request to the control means to make it dark, the control means displays the detection result of the human detection means. The automatic control based on this is interrupted, the light is turned off, the blinds are closed, and the light control target space is darkened. In the state where the light control target space is darkened according to the manual operation request, when the occupant operates the controller and sends an automatic control request to the control means, the control means interrupts the control according to the manual operation request, Return to the automatic control based on the detection result of the human detection means.

In the present invention, only one controller may be provided on the wall of the dimming target space. However, for example, if one is provided on a chair placed in the dimming target space, The request can be immediately transmitted to the control means while sitting on the chair. In the present invention, only one person detecting means may be provided on the ceiling of the light control target space. However, if one person detection means is provided, for example, on a chair placed in the light control target space, Detection of the presence / absence of the is ensured.
In the present invention, the manual operation request from the occupant to the control means via the operating device may be a turn-off request for turning off the illumination, a blind closing request for closing the blind, or the like. It may be a request for designating the opening.

  Moreover, in this invention, the light control object space may be comprised by the divided light control zone. In this case, an operation device is provided for each dimming zone, and a transmission unit is provided for sending a request from a room occupant in each dimming zone input to each through the operation device to the control unit. Then, when a manual operation request is received as a request from an occupant via the operation device, the control unit interrupts the light control based on the detection result of the human detection device to the dimming zone where the operation device is provided. If the automatic control request is received as a request from the occupant via the operation device according to the received manual operation request, the light control to the dimming zone is performed. The control of the light according to the manual operation request is interrupted, and the control of the light to the dimming zone is returned to the control based on the detection result of the human detection means.

  Further, in the present invention, when the dimming target space is constituted by the divided dimming zones, the occupant detection means is configured for each dimming zone based on the detection result from the human detection means provided for each dimming zone. A means for determining whether or not a person is present is provided, and a person detection means and an operating device are provided on a chair placed in the dimming zone. In this case, the person detecting means corresponds to, for example, a seating detection sensor provided on the chair, and the means for determining whether or not there is a person for each dimming zone corresponds to, for example, a CPU provided in the lighting controller or the blind controller.

  According to the present invention, the light to the dimming target space is normally controlled (automatic control) based on the detection result of the human detection means, and the occupant can send a manual operation request to the control means by operating the operating device. For example, the automatic control based on the detection result of the human detection means is temporarily interrupted, the control according to the manual operation request is executed, and when a special case such as watching the OHP occurs in the meeting, the lighting is turned off or the blind It is possible to darken the light control target space by closing the screen, and to achieve both automatic control of light control and the desire of the occupant.

Hereinafter, the present invention will be described in detail with reference to the drawings.
[Embodiment 1: Lighting control system]
FIG. 1 is a block diagram of an illumination control system showing an embodiment of a dimming control system according to the present invention. In the figure, 1 is a room (light control target space) partitioned into four areas (light control zones: hereinafter referred to as subareas) AR1 to AR4, and 2 is a main illumination provided on the central ceiling of the room 1 Devices (hereinafter referred to as main lighting), 3-1 to 3-4 are sub-lighting devices (hereinafter referred to as sub-lighting) provided on the central ceiling of the sub-areas AR1 to AR4.

In the room 1, a plurality of chairs 4 with a transmission function are provided. The external appearance of the chair 4 with a transmission function is illustrated in FIG. The block diagram of the apparatus mounted in the chair 4 with a transmission function in FIG. 4 is shown.
A chair with a transmission function (hereinafter simply referred to as a chair) 4 includes a CPU 4-1 that executes a message generation program 4 A and a transmission message (described later) generated by the CPU 4-1 as a radio signal via the antenna 4-2. The transmission module 4-3 for transmitting, the battery 4-4 for supplying power to the respective components such as the CPU 4-1 and the transmission module 4-3, and the seating of the user are detected and turned on by the seating of the user A seating detection switch 4-6 for supplying power from the battery 4-4 to the CPU 4-1, etc., a setting device 4-7 for setting various information necessary for control, and the chair 4 Is stored in the storage unit 4-10 as relative coordinates (chair relative coordinates) by accumulating the movement distances of the storage unit 4-8, the timer 4-9, and the chair 4 that store the ID (chair ID) determined for Memorize An operator 4-11, a reset switch 4-12 for clearing the relative coordinates of the storage unit 4-10, and an operating device 4 capable of switching the operation position between two positions "ON" and "OFF". 13 is provided. The operation device 4-13 is attached to the armrest portion of the chair 4 as shown in FIG.

  When a user is seated on the chair 4 (see FIG. 3), this is detected by the seating detection switch 4-6, and the detection information (seat detection information) of the seating detection switch 4-6 is stored in the storage unit 4-8. The transmission message including the chair ID, the relative coordinates stored in the storage unit 4-10, and the setting command (0: “OFF”, 1: “ON”) corresponding to the operation position of the operation device 4-13. Created by the CPU 4-1 and transmitted as a radio signal from the transmission module 4-3 via the antenna 4-2. Thereafter, while the user is seated, a transmission message is intermittently transmitted from the chair 4.

  While the user is seated, the chair 4 detects the current coordinates by the encoder 4-11, and uses the detected coordinates as relative coordinates (x, y) where the fixed position coordinates are (0, 0). 10 and a transmission message in which the relative x coordinate and the relative y coordinate of the chair 4 stored in the storage unit 4-10 are added to the chair ID, the seating detection information, and the setting command are transmitted. The detection of the coordinates of the encoder 4-11 is based on the same principle as that of a mouse. When the error becomes large, the relative coordinates of the storage unit 4-10 are set to “0” by pressing the reset switch 4-12 at a fixed position. be able to.

  For the main illumination 2 and the sub-illuminations 3-1 to 3-4, an illumination controller 5 that sends control commands to the main illumination 2 and the sub-illuminations 3-1 to 3-4 is provided. The lighting controller 5 includes a database 5-1, a CPU 5-2 that executes a lighting control program 5 A that generates control commands for the main lighting 2 and the sub-lights 3-1 to 3-4, and each chair 4 in the room 1. And a receiver 5-3 for receiving a transmission message (chair ID, chair relative coordinates, seating detection information, setting command) transmitted from.

  As shown in FIG. 5, the receiver 5-3 is provided with a CPU 5-31, a reception module 5-32, and a communication module 5-33, and a radio signal from the chair 4 is received by the reception module 5-32. When received, the CPU 5-31 executes the message generation program 5B to perform protocol conversion of the transmission message including the chair ID, chair relative coordinates, seating detection information, and setting command included in the received wireless signal. The transmission message subjected to protocol conversion is sent to the CPU 5-2 via the communication module 5-33.

  In the database 5-1, fixed position coordinates of the chair 4 are registered for the chair ID of each chair 4 provided in the room 1. When the CPU 5-2 receives the transmission message from the receiver 5-3, it reads out the fixed position coordinates of the chair 4 corresponding to the chair ID included in the transmission message from the database 5-1, and the read fixed position coordinates and The absolute coordinate (chair absolute coordinate) of the chair 4 is calculated based on the chair relative coordinates included in the transmission message, and the area number (area No.) where the chair 4 is located from the calculated absolute coordinates of the chair 4 is calculated. This chair 4 area NO. And chair ID are registered in the chair information table TB1 in the database 5-1 as chair information. FIG. 6 (a) shows the chair ID and area No. to the chair information table TB1. The registration status of is illustrated.

  Further, the CPU 5-2 resets and restarts the absence determination timer (soft timer) TM each time the chair 4 in the room 1 receives a transmission message from the receiver 5-3, When the absence determination timer TM expires, it is determined that the user has left the chair 4, and the chair information (chair ID, area) of the chair 4 registered in the chair information table TB1 of the database 5-1 is determined. NO.) Is deleted.

  The lighting controller 5 is given not only the transmission message from each chair 4 but also the external setting information from the external setting device 6. The external setting device 6 is provided for the entire room 1, and “forced off” and “forced on” for the main lighting 2 and the sub-lights 3-1 to 3-4 provided in the room 1. The three modes of “automatic control” can be set individually.

  For example, if “forced off” is set for the main lighting 2, the external setting information from the external setting device 6 indicates “area No. 0” indicating the main lighting and “forced off”. “Input value 0” is sent to the illumination controller 5.

  If “forced off” is set for the sub-illumination 3-1, “area No. 1” indicating the sub-illumination in the sub-area AR1 and “forced off” are set as external setting information from the external setting device 6. "Input value 0" indicating that the lighting controller 5 is sent. In the external setting information, “input value 1” indicates “forced on”, and “input value 2” indicates “automatic control”.

  In the database 5-1, not only the chair information table TB1, but also a sub area data table TB2 and a main lighting data table TB3 are provided, and data rewriting for the sub area data table TB2 and the main lighting data table TB3 is performed by the CPU 5- 2 is performed. FIG. 6B illustrates an initial state of data written in the subarea data table TB2. FIG. 6C illustrates an initial state of data written in the main illumination data table TB3.

  The sub-area data table TB2 is an area number indicating the sub-areas AR1 to AR4 in the room 1. As data items for 1 to 4, “number of people in room”, “external setting device state”, “command”, and “status” are included. In the initial state, “number of occupants” in each sub-area is “0”, “external setting device state” is “automatic”, “command” is “ON”, and “status” is “OFF”. Note that “automatic” in the “external setting device state” indicates that the request from the external setting device 6 for the sub-lighting 3 in the area is “automatic control”. In addition, “ON” in “command” indicates that the request from the occupant for the sub-light 3 in the area is “lighting (automatic control)”, and “OFF” in “status” is in the area. This indicates that the state of the sub-illumination 3 is “off”.

  The main illumination data table TB3 includes an area No. 1 indicating the main area AR0 of the room 1 (a region combining the sub areas AR1 to AR4). As data items for 0, “external setting device state”, “command”, and “status” are included. In the initial state, the “external setting device state” of the main area AR0 is “automatic”, the “command” is “OFF”, and the “status” is “OFF”. Note that “automatic” in the “external setting device state” indicates that the request from the external setting device 6 for the main illumination 2 is “automatic control”. Further, “OFF” of “command” indicates that the request from the illumination controller 5 for the main illumination 2 is “off”, and “OFF” of “status” indicates that the state of the main illumination 2 is “off”. It shows that.

  Hereinafter, the illumination control of the main illumination 2 and the sub illuminations 3-1 to 3-4 executed by the illumination control program 5 </ b> A will be described with reference to flowcharts shown in FIGS. 7, 8, and 9.

[Number of people in the room 0]
As an example, it is assumed that the settings for the main illumination 2 and the sub-illuminations 3-1 to 3-4 from the external setting device 6 are all “automatic control”. Further, it is assumed that the sub area data table TB2 and the main illumination data table TB3 in the database 5-1 are in the initial state shown in FIGS. 6 (b) and 6 (c). In addition, it is assumed that no one is in the room 1 and that the main lighting 2 and the sub-lights 3-1 to 3-4 are all turned off. In addition, it is assumed that the operation position of the operation device 4-13 of all the chairs 4 (41 to 48) in the room 1 is set to the “ON” position.

[Increase in number of people in the room: 0 to 1 person]
In such a situation (see FIG. 10A), it is assumed that a person enters the room 1 and the person is seated on the chair 41 in the sub-area AR1 (see FIG. 10B). As a result, the number of people in the room 1 increases by one, from zero to one. In this case, in the present embodiment, the main illumination 2 and the sub illumination 3-1 are automatically turned on. The operation will be described below.

[Calculation of the number of people in the room]
In the chair 41, when a person is seated, the seating detection switch 4-6 is turned on and the contact 4-5 is closed, whereby the power from the battery 4-4 is supplied to each part of the chair 4 including the CPU 4-1. In addition to being supplied, the CPU 4-1 to which power is supplied is activated to execute the message generation program 4A.

  Here, when the CPU 4-1 first detects that the contact point 4-5 of the seating detection switch 4-6 is turned on, the detection information (seating detection information) and the chairs read from the storage units 4-8 and 4-10, respectively. A transmission message including a setting command (1: “ON”) corresponding to the chair ID and chair relative coordinates of 44 and the operation position (“ON” position) of the operation device 4-13 is created. Then, the created transmission message is output to the transmission module 4-3 and transmitted as a radio signal from the transmission module 4-3 via the antenna 4-2.

  The wireless signal transmitted from the chair 41 is received by the receiver 5-3 of the lighting controller 5. When the CPU 5-31 of the receiver 5-3 receives the wireless signal from the chair 41, the CPU 5-31 converts the protocol of the transmission message including the seating detection information, the chair ID, the chair relative coordinates, and the setting command included in the received wireless signal. And send it to the CPU 5-2 via the communication module 5-33.

  When receiving the transmission message from the receiver 5-3, the CPU 5-2 executes the illumination control program 5A. FIG. 7 is a flowchart showing a start part of the processing operation of the CPU 5-2 according to the illumination control program 5A.

  The CPU 5-2 determines that a person has been seated on the chair 44 based on the seating detection information included in the transmission message from the receiver 5-3 (“attended” in step 101), and the chair ID included in the transmission message. Is not registered in the chair information table TB1 in the database 5-1 (NO in step 102), and the chair ID is registered in the chair information table TB1 (step 103).

  Then, the CPU 5-2 reads out the fixed position coordinates of the chair 41 specified by the chair ID included in the transmission message from the database 5-1, and based on the read fixed position coordinates and the relative coordinates included in the transmission message. The absolute coordinates of the chair 41 are calculated (step 104). From the calculated absolute coordinates of the chair 41, the area NO. (Step 105) and registered in the chair information table TB1 corresponding to the previous chair ID (step 106). In this case, the sub-area AR1 is obtained as the area where the chair 41 is located, and the area NO. 1 is registered in the chair information table TB1 corresponding to the chair ID of the chair 41.

  The chair 41 transmits a transmission message intermittently while the user is seated. In this case, in the flowchart shown in FIG. 7, it is determined that the chair ID included in the transmission message is already registered in the chair information table TB (YES in step 102). The area No. of the sub area where the chair 41 is located, which is obtained from the absolute coordinates calculated from the fixed position coordinates and the relative coordinates. Are updated / registered in the chair information table TB2.

  Next, the CPU 5-2 calculates the number of people in the sub-area AR1 where the chair 41 is located and the total number of people in the main area AR0, that is, all areas, based on the registered contents of the chair information table TB1 (step 110). ). In this case, the number of people in the sub-area AR1 and the total number of people in all areas are calculated as one. After calculating the number of people in the sub-area AR1 and the total number of people in the room, the CPU 5-2 performs a sub-lighting control process and a main lighting control process.

[Main lighting control processing]
FIG. 8 is a flowchart of the main lighting control process executed by the CPU 5-2. The CPU 5-2 accesses the main illumination data table TB3 stored in the database 5-1, and confirms the “external setting device state” for the main area AR0 (step 111). In this example, since the “external setting device state” for the main area AR0 is “automatic”, the process proceeds to step 112.

  In step 112, the CPU 5-2 checks whether or not the total number of people in all areas calculated in the previous step 110 is zero. In this case, since the total number of people in all areas is 1, the main illumination 2 is turned on (step 113). Then, the data of the main illumination data table TB3 is updated (step 114), and both the “command” and “status” are set to “ON”.

[Sub-lighting control processing]
FIG. 9 is a flowchart of the sub illumination control process executed by the CPU 5-2. The CPU 5-2 accesses the sub area data table TB2 stored in the database 5-1, and updates the data in the sub area data table TB2 (step 120). In this example, since the number of occupants in the subarea AR1 is calculated as 1 in the previous step 110, the area No. in the subarea data table TB2 is calculated. 1. Change the “Number of people in the room” from 0 to 1.

  Then, the CPU 5-2 determines the area No. in the sub area data table TB2. 1 is checked (step 121). In this example, area NO. Since the “external setter state” for 1 is “automatic”, the process proceeds to step 122. In step 122, the CPU 5-2 determines whether the area No. It is checked whether the number of occupants in 1 is 0. In this case, area NO. Since the number of occupants in 1 is 1, the process proceeds to step 123. In step 123, the area No. in the sub-area data table TB2 is displayed. It is confirmed whether the “command” and the “status” of 1 match. In this case, since “command” is “ON” and “status” is “OFF”, the process proceeds to step 124 in response to NO in step 123.

  In step 124, the CPU 5-2 determines the area No. in the sub area data table TB2. A command value “ON” of 1 is sent as a control command to the sub-illumination 3-1, and the sub-illumination 3-1 is turned on. Further, the area No. in the sub-area data table TB2 is displayed. “Status” for 1 is changed from “OFF” to “ON”.

[Increase in number of people in the room: 1 to 0]
It is assumed that a person in the sub-area AR1 leaves the chair 41 and goes out of the room 1 from the state shown in FIG. 10B (see FIG. 10C). As a result, the number of occupants in the room 1 is reduced by one, from one to zero. In this case, in the present embodiment, the main illumination 2 and the sub illumination 3-1 are automatically turned off.

[Operation]
[Calculation of the number of people in the room]
Each time the CPU 5-2 receives a transmission message from the chair 41, the CPU 5-2 resets the absence determination timer TM and restarts it. When a person leaves the chair 41, the transmission message is not sent from the chair 41. As a result, the activated absence determination timer TM is timed up. Then, the CPU 5-2 determines that the person has left the chair 41 (“Seating” in Step 101), and the chair ID and area No. of the chair 41 registered in the chair information table TB1. Is deleted (steps 107, 108, 109).

  The CPU 5-2 sends the chair ID and area No. of the chair 41 from the chair information table TB1. Is deleted, the number of people in the sub-area AR1 where the chair 41 is located and the total number of people in all areas are calculated based on the registered contents of the chair information table TB1 (step 110). In this case, the number of people in the sub-area AR1 and the total number of people in all areas are both calculated as 0. After calculating the number of people in the sub-area AR1 and the total number of people in the room, the CPU 5-2 performs a sub-lighting control process and a main lighting control process.

[Main lighting control processing]
The CPU 5-2 accesses the main illumination data table TB3 stored in the database 5-1, and confirms the “external setting device state” for the main area (step 111). In this example, since the “external setting device state” for the main area is “automatic”, the process proceeds to step 112.

  In step 112, the CPU 5-2 checks whether or not the total number of people in all areas calculated in the previous step 110 is zero. In this case, since the total number of occupants in all areas is 0, the main illumination 2 is turned off (step 115). Then, the data of the main illumination data table TB3 is updated (step 116), and the “command” and “status” are both set to “OFF”.

[Sub-lighting control processing]
The CPU 5-2 accesses the sub area data table TB2 stored in the database 5-1, and updates the data in the sub area data table TB2 (step 120). In this example, since the number of occupants in the sub-area AR1 is calculated as 0 in the previous step 110, the area No. in the sub-area data table TB2 is calculated. Change the number of people in 1 from 1 to 0.

  Then, the CPU 5-2 determines the area No. in the sub area data table TB2. “External setter state” for 1 is confirmed (step 121). In this example, area NO. Since the “external setter state” for 1 is “automatic”, the process proceeds to step 122. In step 122, the CPU 5-2 determines the area No. calculated in the previous step 110. It is checked whether the number of occupants in 1 is 0. In this case, area NO. Since the number of people in room 1 is 0, the process proceeds to step 125.

In step 125, area NO. Check the current “status” of 1. In this case, area NO. Since the current “status” of 1 is “ON”, the process proceeds to step 126.
In Step 126, the CPU 5-2 sends “OFF” as a control command to the sub-light 3-1, and turns off the sub-light 3-1. Further, the area No. in the sub-area data table TB2 is displayed. “Status” for 1 is changed from “ON” to “OFF”.

[Increase in the number of people in the room: 1 to 2 people]
Assume that a new person enters the room 1 from the state shown in FIG. 10B and sits on the chair 42 in the sub-area AR1 (see FIG. 10D). As a result, the number of people in the room 1 is further increased by one, from one to two. In this case, in the present embodiment, the lighting of the main lighting 2 and the lighting of the sub-lighting 3-1 are maintained.

[Operation]
In step 110 shown in FIG. 7, the CPU 5-2 calculates the number of people in the sub-area AR1 and the total number of people in all areas as two.
Since the total number of occupants in all areas is two, the CPU 5-2 proceeds to steps 113 and 114 in the main lighting control process shown in FIG. In this case, “ON” is sent to the main illumination 2 as a control command, but since the main illumination 2 is already lit, the lighting state is maintained.

  Further, since the number of people in the sub area AR1 is two, the CPU 5-2 proceeds to the process to step 123 in the sub illumination control process illustrated in FIG. In this case, the area No. in the sub area data table TB2 is displayed. Since “command” and “status” of 1 are both “ON” and coincide with each other, the processing ends in response to YES in step 123. Thereby, the lighting state of the sub illumination 3-1 is maintained.

[Number of people in the room is 1 and the controller is OFF]
Assume that a person sitting on the chair 41 in the sub-area AR1 operates the operation device 4-13 and switches the operation position to the “OFF” position from the state shown in FIG. In this case, in the present embodiment, the sub-illumination 3-1 in the sub-area AR1 where the chair 41 on which the person is seated is turned off (see FIG. 11B). The main illumination 2 is kept on.

[Operation]
The chair 41 transmits a transmission message intermittently while the user is seated. In the chair 41, when the operation position of the operation device 4-13 is switched to the “OFF” position, the setting command included in the transmission message is set to “OFF”. This setting command “OFF” corresponds to “a manual operation request from a resident” in the present invention.

  The CPU 5-2 receives the transmission message from the chair 41, recognizes that the setting command included in the transmission message has been changed from “ON” to “OFF”, and stores the sub-command stored in the database 5-1. Data in the area data table TB2 is updated (step 120 shown in FIG. 12). FIG. 12 is a reprint of the flowchart of the sub-illumination control process shown in FIG. 9 for easy understanding. In this case, the area No. in the sub area data table TB2 is displayed. 1 “command” is changed from “ON” to “OFF”.

  Then, the CPU 5-2 determines the area No. in the sub area data table TB2. 1 is checked (step 121). In this example, area NO. Since the “external setter state” for 1 is “automatic”, the process proceeds to step 122. In step 122, the CPU 5-2 determines whether the area No. It is checked whether the number of occupants in 1 is 0. In this case, area NO. Since the number of occupants in 1 is 1, the process proceeds to step 123. In step 123, the area No. in the sub-area data table TB2 is displayed. It is confirmed whether the “command” and the “status” of 1 match. In this case, since “command” is “OFF” and “status” is “ON”, the process proceeds to step 124 in response to NO in step 123.

  In step 124, the CPU 5-2 determines the area No. in the sub area data table TB2. The command value “OFF” of 1 is sent as a control command to the sub-light 3-1, and the sub-light 3-1 is forcibly turned off. Further, the area No. in the sub-area data table TB2 is displayed. 1 “Status” is changed from “ON” to “OFF”.

  If the sub-light 3-1 is forcibly turned off by a manual operation request from a room occupant, automatic control based on the number of people in the sub-area AR 1 is not performed. That is, when the number of occupants in the sub-area AR1 becomes 0, the area NO. Since the “status” of 1 is “OFF”, the sub-illumination 3-1 continues to be turned off (“OFF” in step 125.) When the number of occupants in the sub-area AR1 is 0, a new person Even if the number of occupants in the area AR1 increases and the number of people in the subarea AR1 increases, the “command” and “status” of the area No. 1 in the subarea data table TB2 are both “OFF”. -1 continues to be extinguished (YES in step 123).

[The number of people in the room is 1 and the controller is ON]
From the state shown in FIG. 11B, it is assumed that a person sitting on the chair 41 in the sub-area AR1 operates the operation device 4-13 and switches the operation position to the “ON” position. In this case, in this embodiment, the sub-illumination 3-1 is turned on, and the automatic control based on the number of people in the sub-area AR1 is restored (see FIG. 11C). The main illumination 2 is kept on.

[Operation]
The chair 41 transmits a transmission message intermittently while the user is seated. In the chair 41, when the operation position of the operation device 4-13 is switched to the “ON” position, the setting command included in the transmission message is set to “ON”. This setting command “ON” corresponds to the “automatic control request from a resident” in the present invention.

  The CPU 5-2 receives the transmission message from the chair 41, recognizes that the setting command included in the transmission message has been changed from “OFF” to “ON”, and stores the sub message stored in the database 5-1. Data in the area data table TB2 is updated (step 120 shown in FIG. 12). In this case, the area No. in the sub area data table TB2 is displayed. 1 "Command" is changed from "OFF" to "ON".

  Then, the CPU 5-2 determines the area No. in the sub area data table TB2. 1 is checked (step 121). In this example, area NO. Since the “external setter state” for 1 is “automatic”, the process proceeds to step 122. In step 122, the CPU 5-2 determines whether the area No. It is checked whether the number of occupants in 1 is 0. In this case, area NO. Since the number of occupants in 1 is 1, the process proceeds to step 123. In step 123, the area No. in the sub-area data table TB2 is displayed. It is confirmed whether the “command” and the “status” of 1 match. In this case, since “command” is “ON” and “status” is “OFF”, the process proceeds to step 124 in response to NO in step 123.

  In step 124, the CPU 5-2 determines the area No. in the sub area data table TB2. A command value “ON” of 1 is sent as a control command to the sub-illumination 3-1, and the sub-illumination 3-1 is turned on. Further, the area No. in the sub-area data table TB2 is displayed. 1 “Status” is changed from “OFF” to “ON”. Thereby, the sub-illumination control in the sub-area AR1 returns to the automatic control based on the number of occupants who were temporarily interrupted.

[Priority after request from controller]
[2 people in the room, the first is the controller OFF]
In the state shown in FIG. 13A, it is assumed that a person sitting on the chair 41 in the sub-area AR1 operates the operation device 4-13 and switches the operation position to the “OFF” position. In this case, the sub illumination 3-1 is turned off (see FIG. 13B). The main illumination 2 is kept on. FIG. 14B shows the update status of the subarea data table TB2 at this time.

[The number of people in the room is 2 and the second is the controller ON]
In the state shown in FIG. 13B, it is assumed that a person sitting on the chair 42 in the sub-area AR1 operates the operation device 4-13 and switches the operation position to the “ON” position. In this case, the sub-illumination 3-1 is turned on, and the automatic control based on the number of people in the sub-area AR1 is restored (see FIG. 13C). The main illumination 2 is kept on. FIG. 14A shows the update status of the sub-area data table TB2 at this time.

  Thus, in this Embodiment, since CPU5-2 receives the request | requirement (manual operation request | requirement, automatic control request | requirement) from the occupant via the operation device 4-12 of the chair 4 with a post-priority, an occupant is occupying You can turn off or turn on the sub-lights in your area at any time you want.

[Operation from an external setting device]
In the above description, it is assumed that all the settings for the main illumination 2 and the sub illuminations 3-1 to 3-4 from the external setting device 6 are “automatic control”. In the present embodiment, the external setting device 6 performs “forced off”, “forced on”, “automatic control” for the main lighting 2 and the sub-lights 3-1 to 3-4 provided in the room 1. These three modes can be set individually.

[Main lighting, forced off]
If “forced off” is set for the main illumination 2 in the external setting device 6, “area No. 0” and “input value 0” are sent to the illumination controller 5 as external setting information. The CPU 5-2 receives the external setting information from the external setting device 6 and receives the area number. Is checked (step 201 shown in FIG. 15). In this case, area NO. Is 0, it is determined as external setting information for the main area, and the input value included in the external setting information is checked (step 206 shown in FIG. 16).

  In this case, since the input value is 0, the CPU 5-2 sends the input value to the main illumination 2 as a control command, and forcibly turns off the main illumination 2 (step 207). Then, the data of the main illumination data table TB3 is updated (step 208), the “external setting device state” is set to “OFF”, and the “status” is set to “OFF”.

  In the main illumination data table TB3, when the “external setter state” is set to “OFF”, the “external setter state” is determined to be “OFF” in step 111 of the flowchart shown in FIG. . In step 117, the total number of occupants in all areas is confirmed. If the total number of occupants is 0, the process proceeds to step 118. If the total number of occupants is not 0, the process proceeds to step 119. In step 118, the data of the main illumination data table TB3 is updated, and the “command” is set to “OFF”. In step 119, the data of the main illumination data table TB3 is updated, and the “command” is set to “ON”.

[Main lighting, forced on]
If “forced on” is set for the main illumination 2 in the external setting device 6, “area No. 0” and “input value 1” are sent to the illumination controller 5 as external setting information. The CPU 5-2 receives the external setting information from the external setting device 6 and receives the area number. Is checked (step 201). In this case, area NO. Is 0, it is determined as external setting information for the main area AR0, and the input value included in the external setting information is checked (step 206).

  In this case, since the input value is 1, the CPU 5-2 sends the input value to the main illumination 2 as a control command, and forcibly turns on the main illumination 2 (step 207). Then, the data of the main illumination data table TB3 is updated (step 208), the “external setting device state” is set to “ON”, and the “status” is set to “ON”.

  In the main illumination data table TB3, when the “external setter state” is set to “ON”, the “external setter state” is determined to be “ON” in step 111 of the flowchart shown in FIG. . In step 117, the total number of occupants in all areas is confirmed. If the total number of occupants is 0, the process proceeds to step 118. If the total number of occupants is not 0, the process proceeds to step 119. In step 118, the data of the main illumination data table TB3 is updated, and the “command” is set to “OFF”. In step 119, the data of the main illumination data table TB3 is updated, and the “command” is set to “ON”.

[Main lighting, automatic control]
If “automatic control” is set for the main illumination 2 in the external setting device 6, “area No. 0” and “input value 2” are sent to the illumination controller 5 as external setting information. The CPU 5-2 receives the external setting information from the external setting device 6 and receives the area number. Is checked (step 201). In this case, area NO. Is 0, it is determined as external setting information for the main area AR0, and the input value included in the external setting information is checked (step 206).

  Here, since the input value is 2, the command value in the main illumination data table TB3 is sent to the main illumination 2 as a control command, and the main illumination 2 is turned on or off (step 209). Thereby, the main lighting control in the room 1 returns to the automatic control based on the number of people in the room that has been temporarily interrupted. Then, the data of the main illumination data table TB3 is updated (step 208), the “external setting device state” is set to “automatic”, and the “status” is set to “ON” or “OFF”.

  In the main illumination data table TB3, when the “external setter state” is set to “automatic”, the “external setter state” is determined to be “automatic” in step 111 of the flowchart shown in FIG. The processing after step 112 is executed.

[Sub-lighting, forced off]
For example, if “forced off” is set for the sub-light 3-1 in the external setting device 6, “area No. 1” and “input value 0” are sent to the lighting controller 5 as external setting information. The CPU 5-2 receives the external setting information from the external setting device 6 and receives the area number. Is checked (step 201). In this case, area NO. 1 is determined to be external setting information for the subarea AR1, and the input value included in the external setting information is checked (step 202).

  In this case, since the input value is 0, the CPU 5-2 sends the input value to the sub-light 3-1, as a control command, and forcibly turns off the sub-light 3-1. Then, the data in the subarea data table TB2 is updated (step 204), and the area No. The “external setting device state” 1 is set to “OFF”, and the “status” is set to “OFF”.

  In the subarea data table TB2, when the “external setter state” is set to “OFF”, the “external setter state” is determined to be “OFF” in step 121 of the flowchart shown in FIG. Processing is no longer performed. Thereby, priority is given to “forced off” of the sub-illumination 3-1 by the external setting device 6 over the automatic control of the sub-illumination 3-1 in the sub-area AR1 and the control according to the manual operation request from the occupant. It becomes.

[Sub-lighting, forced off]
For example, if “forced on” is set for the sub-light 3-1 in the external setting device 6, “area No. 1” and “input value 1” are sent to the lighting controller 5 as the external setting information. The CPU 5-2 receives the external setting information from the external setting device 6 and receives the area number. Is checked (step 201). In this case, area NO. 1 is determined to be external setting information for the subarea AR1, and the input value included in the external setting information is checked (step 202).

  In this case, since the input value is 1, the CPU 5-2 sends the input value to the sub-light 3-1, as a control command, and forcibly turns on the sub-light 3-1. Then, the data in the subarea data table TB2 is updated (step 204), and the area No. The “external setting device state” 1 is set to “ON” and the “status” is set to “ON”.

  In the subarea data table TB2, when the “external setting device state” is set to “ON”, the “external setting device state” is determined to be “ON” in step 121 of the flowchart shown in FIG. Processing is no longer performed. Thereby, priority is given to "forced on" of the sub-illumination 3-1 by the external setting device 6 over the automatic control of the sub-illumination 3-1 in the sub-area AR1 and the control according to the manual operation request from the occupant. It becomes.

[Sub-lighting, automatic control]
For example, if “automatic control” is set for the sub-light 3-1, the external setting device 6 sends “area No. 1” and “input value 2” to the lighting controller 5 as external setting information. The CPU 5-2 receives the external setting information from the external setting device 6 and receives the area number. Is checked (step 201). In this case, area NO. 1 is determined to be external setting information for the subarea AR1, and the input value included in the external setting information is checked (step 202).

  In this case, since the input value is 2, the CPU 5-2 sends the command value in the sub area data table TB2 to the sub illumination 3-1, as a control command, and turns on or turns off the sub illumination 3-1. . As a result, the sub-lighting control in the sub-area AR1 returns to the automatic control based on the number of occupants temporarily suspended or the control according to the manual operation request from the occupants. Then, the data in the subarea data table TB2 is updated (step 204), and the area No. The “external setting device state” of 1 is set to “automatic”, and the “status” is set to “ON” or “OFF”.
