Abstract: The continuous enrichment of campus life and the continuous improvement of campus planning and design have put forward higher requirements for the campus lighting system. Especially in the university campus, the proportion of lighting electricity consumption is as high as 75%.Campus lighting has many features such as large number of lamps, long lighting time, wide range and dispersion. It adopts manual control method, which is complicated in procedure and wastes electric energy. If PLC is selected as the main controller, according to the lighting requirements of different ranges and different time periods, in the campus the lighting system is optimized to save energy and reduce maintenance costs.
