In the present embodiment, it is assumed that application software for lighting control is installed in each of the wireless terminals 5-1, 5-2, 5-3,. Moreover, the area information of the illumination area 11 shown in FIG. 2, that is, the area position information indicating the range of each area in the illumination area 11, and the illumination position information indicating the position of the luminaire 3 installed in each area, It is assumed that it is managed by the controller 1.

  FIG. 3 is a sequence diagram illustrating an example of illumination control in the illumination control system according to the present embodiment. In this embodiment, as an example, using the wireless terminal 5-1 on which the application software is installed, the ON / OFF control of the lighting device 3 in the area # 1 can be exclusively performed from the wireless terminal 5-1. Thus, the case where the controller 1 is set will be described. The following processing can be executed in all the wireless terminals in which the application software is installed.

  First, the wireless terminal 5-1 follows the operation by the user of the own device, and obtains the area information acquisition request for the lighting area 11 (the terminal ID of the own device (telephone number, device ID, MAC address, IP address, etc. (Including the ID of ID) is transmitted to the controller 1 (S1).

  The controller 1 that has received the area information acquisition request via the wireless communication device 2 extracts the terminal ID from the received acquisition request and stores it (S2). Then, the area information of the illumination area 11 is transmitted to the wireless terminal 5-1 (S3).

  The wireless terminal 5-1 that has received the area information via the wireless communication device 2 creates a layout diagram of the illumination area based on the area position information and the illumination position information included in the area information, for example, as shown in FIG. 4. A display screen is displayed (S4). FIG. 4 is a diagram illustrating an example of a layout diagram of the illumination area displayed on the screen of the wireless terminal 5-1. Here, a portion surrounded by a dotted line represents area # 1, area # 2,..., And a black circle represents the position of the lighting fixture 3. In addition, for area # 2, a state where it is already assigned to another wireless terminal is shown.

  Then, when the user of the wireless terminal 5-1 touches the part surrounded by the dotted line in the area # 1, the wireless terminal 5-1 desires to be able to exclusively control the lighting device 3 in the area # 1. Area instruction information (including the terminal ID) is generated and transmitted to the controller 1 (S5). In the present embodiment, it is assumed that no processing is performed even if an area # 2 (a portion surrounded by a dotted line) that has already been assigned to another wireless terminal is touched.

  The controller 1 that has received the area instruction information via the wireless communication apparatus 2 checks the assignment table shown in FIG. 5 as to whether or not the area # 1 indicated by the area instruction information is assigned to another user. (S6). FIG. 5 is a diagram illustrating an example of an allocation table, and is stored in a state in which an area number in the illumination area 11 and an allocated wireless terminal are associated with each other. Here, as an example, area # 2 is assigned to wireless terminal 5-2 having terminal ID: “bbbb”, and area # 3 is assigned to wireless terminal 5-3 having terminal ID: “cccc” It is shown. In addition, with respect to area # 1 and area # 4, a state in which they are not assigned to any wireless terminal is shown.

  Then, after confirming that the area # 1 is not assigned to any wireless terminal, the controller 1 puts the wireless terminal 5-1 in the “assigned terminal ID” column of the area # 1 of the assignment table shown in FIG. Terminal ID: “aaaa” is written (S7). Furthermore, the ON / OFF control by the switch 6a to the lighting fixture 3 in the area # 1 is invalidated (S8). That is, the lighting fixture 3 cannot be turned on / off even if the switch 6a is operated.

  Thereafter, the controller 1 sets the lighting control permission information as information indicating that the controller 1 has been set so that the wireless terminal 5-1 can exclusively control the ON / OFF of the lighting fixture 3 in the area # 1. It transmits to the wireless terminal 5-1 (S9). When the controller 1 receives a plurality of area instruction information with different terminal IDs, the controller 1 assigns area # 1 to the wireless terminal that transmitted the area instruction information received earliest. In this case, the controller 1 transmits the illumination control impossibility information to the wireless terminal that cannot allocate the area # 1.

  The wireless terminal 5-1 that has received the lighting control permission information via the wireless communication device 2 thereafter exclusively performs ON / OFF control of the lighting fixture 3 in the area # 1 in accordance with the operation of the user of the own device. (S10). In S10, when performing ON / OFF control of the lighting fixture 3 in area # 1, the wireless terminal 5-1 transmits, for example, control information (including the terminal ID) indicating information indicating ON or OFF to the controller 1. To do. On the other hand, the controller 1 that has received the control information via the wireless communication apparatus 2 refers to the assignment table shown in FIG. 5 to check whether the terminal ID included in the control information is stored in association with the area # 1. . And the controller 1 performs ON / OFF control of the lighting fixture 3 of area # 1 according to the instruction | indication of control information, when terminal ID and area # 1 which are contained in control information are linked | related and memorize | stored.

  Then, when canceling exclusive control of the lighting fixture 3 in the area # 1, the wireless terminal 5-1 transmits a cancellation notification (including the terminal ID) to the controller 1 in accordance with the user's operation (S11).

  The controller 1 that has received the cancellation notification via the wireless communication device 2 sets the terminal ID “aaaa” of the wireless terminal 5-1 described in the “assigned terminal ID” column of the area # 1 of the assignment table shown in FIG. Delete (S12). And the ON / OFF control by the switch 6a to the lighting fixture 3 of area # 1 is validated (S13). That is, the lighting device 3 can be turned on / off by operating the switch 6a. Thereafter, the controller 1 transmits a release completion notification indicating completion of the release to the wireless terminal 5-1 (S14). Thereafter, ON / OFF control of the lighting fixture 3 in the area # 1 is performed by operating the switch 6a.

  [Operation of Controller 1] Next, the operation of the controller 1 in the present embodiment will be specifically described. FIG. 6 is a flowchart showing an example of the operation of the controller 1. In the present embodiment, control for area # 1 will be described. The control for other areas is the same.

  In the initial state, the controller 1 waits for the operation of the switch 6a with respect to the area # 1 (S21, No, S22, No), and when the switch 6a is operated (S22, Yes), the lighting device 3 of the area # 1 The ON / OFF control is performed (S23), and the operation of the switch 6a for the area # 1 is again waited (S21, No, S22, No). Then, the controller 1 receives the area instruction information from the predetermined wireless terminal, and thereby disables the control of the luminaire 3 in the area # 1 by the switch 6a (S21, Yes) until step S21 to step S23. Repeat the process. Here, as an example, the following operation will be described assuming that the wireless terminal 5-1 has transmitted the area instruction information.

  When the control to the lighting fixture 3 in the area # 1 by the switch 6a is invalidated (S21, Yes), the controller 1 waits for ON / OFF control from the wireless terminal 5-1 (S24, No, S25, No ). If there is ON / OFF control from the wireless terminal 5-1 (S <b> 24, Yes), the controller 1 performs ON / OFF control of the lighting fixture 3 in area # 1 (S <b> 26), and again the wireless terminal 5. Wait for ON / OFF control from -1 (S24, No, S25, No). Thereafter, the controller 1 performs processing for waiting for ON / OFF control from the wireless terminal 5-1 (S24, No, S25, No) and ON / OFF control (S26) of the lighting fixture 3 in the area # 1. It is repeatedly executed until a release notification is received from -1. And when the cancellation | release notification is received from the radio | wireless terminal 5-1, (S25, Yes), the controller 1 validates control to the lighting fixture 3 in area # 1 by switch 6a, and operates switch 6a with respect to area # 1. (S21, No, S22, No).

  [Effects of Embodiment] As described above, in the lighting control system of the present embodiment, for example, the wireless terminal 5-1 desires to be able to exclusively control the lighting fixture 3 in the area # 1. When the area instruction information is transmitted and the control of the lighting fixture 3 in the area # 1 is permitted as a response, the lighting fixture 3 in the area # 1 is controlled. In addition, the controller 1 determines whether or not the area # 1 indicated by the area instruction information has been allocated. If the area is not allocated, the controller 1 invalidates the switch control to the lighting fixture 3 in the area # 1, and the wireless terminal Control from 5-1 to the lighting fixture 3 in area # 1 was permitted. Thereby, it becomes possible for a specific individual to exclusively control ON / OFF of illumination of a predetermined area in an illumination area shared by a plurality of users.

  In the present embodiment, when the controller 1 receives a plurality of area instruction information having different terminal IDs, the controller 1 assigns a desired area to the wireless terminal that transmitted the area instruction information received earliest. However, it is not limited to this. For example, the controller 1 stores in advance the terminal ID of the wireless terminal in which the application software is installed and the priority order of the wireless terminal having the terminal ID, and receives a plurality of area instruction information having different terminal IDs. In this case, a desired area may be assigned to the wireless terminal with the highest priority.

  In the present embodiment, in the process of step S5, no processing is performed even if the area # 2 (the part surrounded by the dotted line) that has already been assigned to another wireless terminal is touched. This is not a limitation. For example, when the priority is set as described above, the user of the wireless terminal 5-1 touches the portion surrounded by the dotted line in the area # 2, so that the wireless terminal 5-1 It is also possible to generate area instruction information (including a terminal ID) indicating that the lighting fixture 3 in the area # 2 can be controlled exclusively and transmit it to the controller 1. As a result, the controller 1 makes a determination based on the priority order, and can assign area # 2 to the wireless terminal (wireless terminal 5-1 or wireless terminal 5-2) with the higher priority order. That is, when the priority order of the wireless terminal 5-2 is higher, the assignment table of FIG. 5 is maintained without being updated, and when the priority order of the wireless terminal 5-1 is higher, the assignment table of FIG. Is updated from the current “bbbb” to the terminal ID of the wireless terminal 5-1: “aaaa”.

  As mentioned above, although embodiment of this invention was described, this embodiment is shown as an example and is not intending limiting the range of invention. The present embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. This embodiment and its modifications are included in the scope of the present invention and the gist thereof, and are also included in the invention described in the claims and the equivalents thereof.
