Such a system is provided with one or more optical sensors, and a variable resistor or the like is provided corresponding to each optical sensor. Then, the sensitivity, output level, etc. of each optical sensor was corrected using the 77 resistors and the like in accordance with the snow conditions at the location where each optical sensor was installed.

In such a conventional type, an adjustment means is required for each optical sensor/the stem is complicated, resulting in increased costs - sink marks, etc.

(Explanation of 10 examples of ability) The present invention will now be described in detail with reference to the drawings.

FIG. 1 shows the configuration of a lighting control system according to an embodiment of the present invention. The / stem in the same figure represents a main operation panel 1 and a plurality of terminal devices 3-1 connected to the main operation panel 1 via a transmission line 2.
．． 3-2. ..., 3-n1 One or more lighting loads 4 connected to each terminal, and optical sensors 5-1.5-
2. ..., 5-m, etc.

The main operation panel 1 also includes a processor, a sensor control section, etc. (not shown).

In the system shown in FIG. 1, the main operation panel 1 controls the lighting, turning off, and dimming of the lighting loads connected to each terminal by the action of 70 processors. Each terminal 3-1, 3-2
,...,3-n is connected to the main operation panel 1 via the transmission line 2.
and a circuit that controls each lighting load 4, ie, performs lighting, extinguishing, dimming, etc., based on the received control word. Sterilization of the illuminance of each lighting load is carried out by adjusting the flow angle of the power supply, for example, in 10% increments in the range from 20% to 100% of the maximum illuminance, according to the open side 1 signal using a Zyristor or the like.

FIG. 2 shows the sensor control section provided in the main operation panel l in the system of FIG. 1 and the circuit configuration around it. The circuit shown in the figure includes a sensor control section 6, a timer 7, a timer setting section 8, a level setting section 9, and a memory section [0.

In the circuit shown in FIG. 2, the output from each optical sensor, that is, the analog signal tl, is applied to the sensor control section 6 as analog human power. The sensor unit 6 outputs the illumination load corresponding to each sensor according to analog human power. ! 1
1. The digital output becomes part of the control signal and is transmitted from the main operation panel 1 to each terminal to perform desired dimming control. In this case, the analog manual pressure range is specified by the level setting section 9)11.
If the analog input from the optical sensor is within this range, the dimming control of the corresponding lighting load is performed.The level setting unit 911J, for example, has a keyboard, etc. 〇Specify the encirclement/Hf can be placed in the area.

That is, as shown in FIG.
point) to 2V (point D),
The sensor control unit 6 associates the range of this analog input with the dimming control range A to B of the lighting load and generates a digital output. Now, the dimming range of a certain lighting load is 8, which is the maximum brightness.
Assuming that the range is set from 0% (point A) to 20% (8 points), when the analog input from the optical sensor is at point C, or 0.6V, the illuminance is controlled to 80%, and the analog input is at point D, or 0.6V. The illuminance is controlled to be 20% when the voltage is 2V. Then, when the analog input is an intermediate value between point C and point 13, proportional distribution is applied to 1 from point A to point 13.
・Illuminance can be divided into one of 11 ranges.

1, the analog input range is 3 depending on the level setting section 9.
Assuming that the range is specified from V (C') to 3.8V (D'), this range is the lighting load dimming control 1/1.
Corresponds to χ range A or B.

In the circuit shown in Fig. 2, the timer 7 is used to provide an appropriate time difference between the analog manual input and the digital output, and the timer setting unit 8 sets the timer 7 to a certain number of hours. It is something. Further, the memory section IO temporarily stores the r-event etc. inputted by the level setting section 9.

For example, in a system where time scale information indicating the maximum illuminance for each season is stored in the main operation panel, and the brightness of the lighting load is adjusted according to the season based on this time scale information, The brightness at point A, the upper limit range of the desotal output shown in FIG. 3, is the illuminance indicated by this time scale information. Further, the lower limit point B of the denotal output in FIG. 3 is normally set to the minimum illuminance of the system, for example, 20%.

(Effects of the Invention) As described in Section 2 below, according to the present invention, the voltage range of the optical sensor can be arbitrarily set by the level setting unit 9, so the sensitivity adjustment of the optical sensor can be adjusted depending on the lighting load. It can be arbitrarily and easily set depending on the situation of the installed place. In addition, it is possible to perform appropriate dimming control even in a system that controls the brightness of a lighting load by narrowing down the brightness from the maximum illuminance based on time schedule information or the like.

Furthermore, since there is no need to adjust the sensitivity of each optical sensor using a variable resistor or the like, the amount of manpower required to correct the sensitivity of the optical sensor can be reduced and highly accurate settings can be made.
