The utility model has the beneficial effects of detecting the illuminance through the light detection circuit, distinguishing daytime from darkness, turning on and off lighting street lamps in time, achieving the effects of convenient management and energy saving, and the utility model has a simple structure and is easy to popularize.

Description of drawings

Below by accompanying drawing, the utility model will be further described.

Accompanying drawing 1 is the electrical schematic diagram of the utility model.

Detailed ways

See Figure 1. The single-chip microcomputer adopts PIC12C508 eight-bit single-chip microcomputer.

The light detection circuit is composed of a photosensitive resistor R and a switch tube G. The output end of the light detection circuit is connected to the input end of the single-chip microcomputer PIC12C508, and the output end of the single-chip microcomputer PIC12C508 is connected to the switch tube connected to the relay coil. The output end of the switching tube is connected to the coil of the relay, the normally open contact of the relay is connected to the coil of the power contactor, and the normally open contact of the power contactor is connected to the inlet and outlet of the live line of the street lamp in the community.

The light detection circuit detects light intensity. In the dark state, the photosensitive resistor R has a high resistance, the base bias voltage of the switch tube G is almost zero, the switch tube G is cut off, the switch tube G outputs a high level to the input terminal of the microcontroller, and the output terminal of the microcontroller outputs a high level, The switch tube connected to the relay coil is turned on, the relay is controlled to pull in, and then the power contactor is controlled to pull in, the normally open contact of the power contactor is closed, and the live wire of the street lamp in the community is connected. Conversely, in the daylight state, the photoresistor R has low resistance, the base bias voltage of the switch tube G turns on the switch tube G, the switch tube G outputs a low level to the input terminal of the microcontroller, and the output terminal of the microcontroller outputs a low level , the switch tube connected to the relay coil is cut off, the control relay changes from pull-in to break-off, the power contactor changes from pull-in to break-off, and the normally open contact of the power contactor disconnects the live wire of the street lights in the community, thus realizing the street lights in the community. Intelligent management.
