Design of Automatic Energy-saving System of Public Buildings on Campus

In order to solve the electrical safety and electricity energy waste problem in public buildings on campus,an automatic energy-saving system was designed.It could control power supply and lighting power supply according to the visible light intensity and human signal,avoiding the lights turning on during the day or nobody,so as to avoid fires due to the electrical equipment still working after people leaving.Considering human factors,the manual switch was added in the systems,with clock calendar circuit and PC interface circuit equipped,convenient for the school's daily management and remote monitoring.The system was simple and flexible control,achieving the safety and energy management for a variety of public building power supply systems.
