In a normal process, the device for notifying the state of the sensor terminal 10, the monitoring terminal 3, etc., the main operation panel 1, and the control terminal 2 perform the following operations. That is, the sensor terminal 10, the monitoring terminal 3, etc. detect the state of the sensor and switch provided corresponding to this, and hold | maintain the data which concern on this detection result. The main operation panel 1 collects data held by the sensor terminal 10 and the monitoring terminal 3 by periodic polling and creates control data based on the collected data and stores it in the memory 113. Then, whether or not it is necessary to send control data to the control terminal 2 is detected, and if necessary, it is transmitted with an address.
Further, the control terminal 2 performs lighting control using the control data stored in the memory 33 while waiting for the arrival of the control data. When the control data arrives, the memory 33 is rewritten using the control data, and illumination control is performed using the new control data in the memory 33.
[0014]
FIG. 4 shows a more detailed block diagram in the main operation panel 1 according to the present embodiment. A timer 19 is attached to the sequential dimming control means 16. The illumination state table 18 stores illumination state information for each area. Here, the one floor of a building is surrounded by a wall 60 as shown in FIG. 6, and nine control terminals 2 individually control nine areas. That is, although it is wide and narrow, areas 1 to 9 are illuminated by the illumination load 5 of each area. Accordingly, the illumination state table 18 also stores illumination state information for each of the nine areas. Further, the main operation panel 1 is provided with a dimming control register 22 in sequence. In this sequential dimming control register 22, information on the dimming level and lighting (UP) / extinguishing (DOWN) classification is written in correspondence with the area where the dimming is performed sequentially. Further, the main operation panel 1 indicates whether the lighting / extinguishing is performed immediately or the lighting control level is sequentially changed to light / extinguish when a switch for instructing lighting / extinction is operated in each area. A reference area table 23 is provided in which an area for obtaining illumination information to be referred to when determining is stored. In this embodiment, basically, the illumination state of the adjacent area is referred to. However, since the area 1 is large, when the lighting load on / off is controlled, the illumination state of all areas is referred to. The sequential dimming control means 16 receives an instruction to turn on / off by the switch 6 and obtains an area to be referred to for the corresponding area from the reference area table 23. The lighting state table 18 is searched for the area obtained here to obtain lighting state information. Based on this lighting information, it is determined whether to immediately turn on / off the lighting load in the corresponding area or to change the dimming level sequentially to turn on / off. For example, if even one area is in a lighting state or is illuminated at a predetermined dimming level or higher, it is determined that the dimming control is performed sequentially. Lighting instruction information (control data including the dimming level) based on this determination is output to the transmission line 4 together with the address of the corresponding control terminal 2 to perform dimming control.
[0015]
The control by each means described above is actually performed by the processor 112 of the main operation panel 1 operating by using the program of the flowchart shown in FIG. The processor 112 detects whether or not the on / off control for the illumination load in the predetermined area is performed by the switch 6 from the monitoring terminal 3 via the transmission line 4 (501). Here, when on / off control is performed on the illumination load of the predetermined area, a reference area is searched from the target area related to the on / off control using the reference area table 23 shown in FIG. 4 (502) ). For the reference area obtained as a result of the search, the illumination state information is obtained by referring to the illumination state table 18 and, for example, it is illuminated in a condition that even one area is in a lighting state or a predetermined dimming level or more. Whether or not dimming control is necessary is sequentially detected by detecting whether a predetermined condition such as a condition is met (504).
[0016]
In the above, for example, in the case where none of the reference areas are lit and there is no person, the process proceeds to step 511, and control data is sent to the corresponding control terminal 5 so as to be turned on / off immediately ( 511), the lighting state information is written in the corresponding area of the lighting state table 18 (512) and the end. On the other hand, when it is detected that the dimming control is necessary, whether the dimming area is to be increased, whether the dimming level should be increased or decreased, and the current dimming level is sequentially set in the empty dimming control register 22 Write in correspondence with the area (505), start the timer 19 (506), and set a predetermined time to control the dimming level (the time when the person is unaware of the change in illuminance, for example, 0.5 seconds ) Is monitored (507). When a predetermined time elapses, control data is sent out so as to change the light control level by a predetermined amount (in such a degree that the change in illuminance is not noticeable by the person), and the lighting state based on this is sent to the lighting state table 18. Then, the dimming level is sequentially written to the dimming register 22 (508), and it is checked whether the dimming has progressed to the limit, that is, the lighting / extinguishing state (509), and the end of the dimming control is detected sequentially (510). , Step 507 to Step 510 are repeated. In the case of the end of the sequential dimming control, the lighting state information is written in the corresponding area of the lighting state table 18, and the necessary area of the dimming control register 22 is sequentially cleared (512), and the end.
[0017]
In the embodiment, the control data is sent sequentially. However, in the other embodiments, only the control data indicating which control method is adopted is sent from the main control panel 1, and the control terminal 5 side Sequential dimming control or immediate on / off control should be performed. By controlling in this way, more free time of the transmission line 4 can be secured. Further, for example, by defining only adjacent areas as reference areas, the reference area table 23 is not necessarily required, and conversely, the area that is not close by the reference area table but is affected by turning on / off. Lighting conditions can be taken into account.
[0018]
【The invention's effect】
As described above, according to the present invention, when there is a lighting / extinguishing instruction by the switch means that instructs lighting / extinguishing for each area with respect to the lighting load, the lighting of at least the adjacent area of the lighting state table is received in response to the instruction. Based on the status information, it is determined whether to immediately turn on / off the lighting load in the area or to change the dimming level in sequence to turn on / off, and dimming the lighting instruction information based on this determination Since the dimming control is performed by giving to the means, there is little effect on the person by the lighting load that is turned on / off, and there is an effect that the lighting control is performed without waste.
