Abstract: The interior lighting system of office building has the problems of high energy consumption and low stability. An interior lighting system based on PLC was designed. The upper computer is connected with the environmental light collection circuit unit and other components, and the dual control mode is used for intelligent control of office lighting to complete the overall structure of the system. The hardware of the system focuses on the design of indoor environment light acquisition unit, human body signal acquisition unit, etc., the software repeatedly calls subprograms through the main program to complete the control of the whole system operation. The experimental results show that the average energy consumption of the system is 50 J, the average reaction time is 0.2 s, and the maximum operation stability coefficient is 0.99. The system reduces the energy consumption and reaction time of lighting operation, and improves the stability of system operation.
