  The user UI inputs necessary items to the input fields 25a and 25b using a keyboard (not shown), and then moves the cursor to the button 25a and left-clicks.

  Then, the personal computer P1 uses the user ID input through the input window 25, the group #, and the address # of the lighting fixture SL specified by the selection range 22 (in FIG. 5, addresses # 1, 2, 4, 5). ), The OK button 25c is selected with the mouse, and an instruction signal indicating this information is transmitted to the system server 2 via the network 11.

  By such an operation, it is possible to selectively set or change and set the lighting fixture SL having a desired address # corresponding to the group # for each user.

  In FIG. 2, an illumination area E2 desired by the user U2 is shown, and this illumination area E2 specifies, for example, each luminaire SL of addresses # 4, 5, 8, and 9.

  The system server 2 includes a CPU 2a that controls the entire system and a ROM 2b that stores the allocation information table.

  The ROM 2b constitutes a storage area for storing a program executed by the CPU 2a, a control terminal S connected to the lighting master O, correspondence (allocation) information with the lighting fixture SL, an address #, and the like.

The status table and allocation information table stored in the ROM 2b are shown in FIGS.
As illustrated in FIG. 3, the state table includes data indicating an on / off state for each address # of the lighting fixture SL, for example.

  In addition, in the state table, for example, in FIG. 3, each of the lighting fixtures SL at addresses # 1, 2, 4, and 5 is in an on state, and the lighting fixture SL at an address # 3, 6, and 7 is in an off state Yes.

The CPU 2a determines whether or not the user ID and group # related to the setting or change request transmitted from the personal computer P by the user U are in the allocation information table 2 shown in FIG.

  In this case, if it is determined that the user ID and group # related to the setting or change request are not in the allocation information table, the process proceeds to step S2, and if it is determined that the user ID and group # are present, the process is performed. The process proceeds to S4.

  In the process of step S2, the CPU 2a writes the user ID, group #, address # and the like related to the setting or change request to the allocation information table 2, and the process proceeds to step S3.

  On the other hand, in the determination process in step S4, it is determined that the user ID and the group # related to the setting or change request are in the allocation information table 2. The CPU 2a writes so as to update the assignment of the lighting fixtures set to the group # in the assignment information table 2 shown in FIG. 4, and the process proceeds to step S3.

  In the determination process of step S3, the CPU 2a determines whether or not the content of the setting or change is ON for the lighting fixture SL.

  If it is determined in step S3 that the setting or change is ON for the luminaire SL, the CPU 2a turns on the luminaire SL of the address # related to the setting or change in step S6. At the same time, the instruction signal is generated, and at the same time, the operation state of the luminaire SL of the corresponding address # is written to the server state table 1 shown in FIG. .

  On the other hand, if it is determined in step S3 that the setting or change is not on for the lighting fixture SL, that is, it is off, the process proceeds to S5.

  In step S5, referring to the state table 2, it is determined whether or not the other group # including the luminaire SL related to the setting or change has already been turned on.

  If it is determined in step S5 that there is an already-on group #, the process proceeds to step S7. If it is determined that there is no group #, the process proceeds to step S8.

  In step S8, the CPU 2a writes to the server state table 1 shown in FIG. 3 so that the luminaire SL of the address # related to the setting or change is changed from the on state to the off state, that is, from “1” to “0”. The process proceeds to step S9.

  In step 7, the lighting fixtures other than the lighting fixtures in the other group # in the lighting fixture SL of the address # related to the setting or change are turned off, that is, from “1” to “0”. Thus, the server status table 1 shown in FIG. 3 is written, and the process proceeds to step S9.

  Then, in the process of step S9, the CPU 2a transmits on / off information in the lighting fixture SL of the address # set or changed by the user as an instruction signal to the corresponding lighting master device O.

  Further, the CPU 2a of the system server 2 always executes the program shown in FIG. 7, and in the process of step S10, integrates the power consumption of the lighting fixture SL being turned on using an unillustrated integrating unit, and the integration result Is constantly updated so as to be written in “integrated power W” in the allocation information table 2 shown in FIG. Note that the integrated power of the luminaire SL by the process of step S10 may be, for example, one integrated every day, every week, or every month, and the integration period is appropriately set as necessary. It is also possible.

  Further, when the CPU 2a of the system server 2 acquires the on / off operation information of the lighting fixture SL from the lighting master device O by monitoring the operation state of the lighting master device O, the CPU 2a executes the program shown in FIG. The update control of the state table 1 shown in FIG. 3 is performed so as to be on / off operation information of the lighting fixture SL according to the above. That is, the state table 1 shown in FIG. 3 always represents the on / off operation state of the latest lighting fixture SL.

  The on / off operation information of the lighting fixture SL from the lighting master O is, for example, lighting corresponding to the operation state at this time when a predetermined lighting fixture SL is turned on / off by an operation of the wall switch 5 or the like. It can be obtained by monitoring with the main unit O.

  Further, in the present embodiment, the lighting base unit O, such as on / off information of the lighting fixture SL transmitted from the system server 2 when the on / off signal of the lighting fixture SL is supplied from the wall switch 5, etc. The on / off control of the corresponding lighting fixture SL is given priority over the on / off signal of the lighting fixture SL from the wall switch 5 over the instruction signal.

  Therefore, according to the present embodiment, the allocation information set by assigning the address of each lighting fixture and the on / off operation state of each lighting fixture in advance for each group can be freely changed and set for each user. Can be realized.
