Residential Lighting System

This paper introduces a general residential lighting system of various components. Mainly have a machine of the upper part and lower part and hardware part. PC using kingview 6.55 composition control and monitor screen, as well as complete and the next bit machine communication function. Under a machine adopts PLC control, PLC from PC to accept the command output. Hardware part adopted by controlling thyristor conduction cycle method of the light bulb brightness control circuit. The upper computer part includes the control and monitoring screen of the lower computer, and the report interface of various data can control and monitor the lighting switches in the residential area in real time. Using PLC communication and output safe and reliable, the lower computer ensures the reliability of the system to a certain extent. The part of the hardware circuit adopts the mechanism of controlling the brightness through the photoresistor, so that the illumination brightness can change with the change of the natural light intensity, which plays the role of energy saving and brightness adjustment.
