The dimming control terminal 2 receives the dimming data, generates a dimming control signal for each control group, and adds the dimming control signal to the dimming control terminals of the dimming lighting fixtures 61 to 6n via the transmission line 72. is there. Further, the on / off control terminal 3 receives the on / off control data and controls on / off of the power supply circuits connected to the lighting power source 5 by the electronic terminals of the dimming lighting fixtures 61 to 6n. Further, the wall switch 4 transmits the ON / OFF setting data to the main operation panel 1.

With this configuration, when the main operation panel 1 transmits the on / off control data and the dimming data to which the address of the dimming lighting fixture is added based on the setting data of the time scheduler, etc., the on / off control terminal device 3 By reading this, the power supply circuits of the dimming lighting fixtures 61 to 6n are controlled to be turned on and off, and the dimming control terminal 2 reads the dimming data, and the dimming with a rectangular wave having a duty ratio corresponding to the dimming data. A control signal is continuously generated and added collectively to the dimming control terminals of the dimming lighting fixtures 61 to 6n. As a result, blinking control of the dimming lighting fixtures 61 to 6n of one control group installed corresponding to a predetermined lighting area and collective dimming control are performed. The wall switch 4 sets the blinking state of the lamps 71 to 7n. When the setting data with an address is sent to the main operation panel 1, the main operation panel 1 correspondingly turns on / off control data. And send dimming data. In addition, by an operation switch (not shown) provided on the main operation panel 1, or
The dimming control of the dimming lighting fixtures 61 to 6n is also possible by a sensor or the like that is connected to the main operation panel 1 and detects the state of the electric lock.

[Problems to be solved by the invention]

The above-described lighting control system can be centrally managed by providing the main operation panel 1 in a manager's room or the like.
However, although this main operation panel 1 is provided with a time scheduler and setting switch, it does not have a display for displaying the dimming illumination state, and whether or not the blinking state of many lamps is normal, or even if it is normally lit. There was a problem that it was difficult to monitor whether or not the illuminance was appropriate.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to obtain a lighting control system capable of centrally monitoring the dimming lighting conditions of a large number of dimming lighting fixtures.

[Means for solving problems]

The dimming control system according to the present invention performs a logical operation process on the on / off control data and the dimming data transmitted by the operating device in response to the setting operation, and displays the load state of the dimming lighting fixture. It is equipped with a device.

[Action]

According to the present invention, since the display device for displaying the load state of the dimming lighting fixture is provided, the states of all the dimming lighting fixtures can be easily and centrally monitored only by visual inspection.

〔Example〕

FIG. 1 is a block diagram showing a configuration of an embodiment of the present invention, and particularly, a detailed configuration of the main operation panel 1 and a load state display for displaying a control state of the dimming lighting fixture based on the internal data thereof. The structure of the apparatus 8 is shown. In the figure, the main operation panel 1 is a time scheduler 11 that outputs a blinking and dimming setting signal to a predetermined dimming lighting fixture and a dimming lighting fixture by setting operation. An operation switch 12 that outputs a blinking and dimming setting signal at any time, and a signal processing unit 13 that processes these setting signals, signals indicating the state of the sensor 10, and the like, and generates on / off control data and dimming data. , A signal input / output unit 14 for sending out the on / off control data and the dimming data to the transmission line 71 and for fetching the setting data of the wall switch 4 (FIG. 2) into the signal processing unit 13. ing.
