摘要
交通灯对保障城市交通安全、有序、快捷运行非常重要。利用专为工业环境设计的PLC控制交通灯,运行稳定可靠、抗干扰能力强、控制灵活有效、动作精确、易于维护和检修。本文通过分析控制要求,设计了基于西门子S7-200 PLC一个定时器的交通灯控制的硬件系统和软件系统,适合目前我国交通控制与管理的现状。
Traffic lights on the city traffic safety guarantee, orderly, efficient operation is very important. The PLC traffic lights which is specifically designed for industrial environment has characteristics of high reliable, control flexibility, an- ti-interference ability, stable and reliable operation, easy maintenance and repair. This paper designs the hardware and the software of the traffic light control system based on Siemens S7-200 PLC , selected to fulfill control system requisi- tion and adapted to the current traffic control in China.
