| Abstract: | PLC (programmable logic controller) is an important method and basic equipment in industrial control. The paper describes the advantages of traffic control system with PLC, and presents the design procedure of PLC traffic signal control system. According to the realistic control requirement of urban road signalized intersections, with the Panasonic FPX-C30 PLC, the paper describes the pass through states of antagonistic vehicle streams at signalized intersections and sets forth the design procedure and programming method of PLC control program under different phase sequence. |
