摘要
随着我国城市和交通的迅速发展,交通管制日趋重要。原有的信号灯控制器已不能满足现实需要。城市道路交通信号PLC控制系统运行可靠,可实现交通信号管制的自动开停,控制方案的调整及优化简单易行,使用范围广、寿命长。文章对该控制系统的设计过程、设计思路、编程方法做了详尽的介绍,具有一定的参考价值和实用价值。
With the rapid development of traffic in city, the trafic control is becoming more and more important. The traditional control of traffic light can't meet the new requirement, but the PLC control system for traffic light can. It is ireliable and convenient, can realize the time switch of the traffic light, and make the adjustment and optimization of the traffic control solution easy. procedure and idea of design of the PLC control system as well as the programming key points are introduced in the article, and it is practical and useful in certain degree.
