摘要
介绍PLC在十字路口交通灯中的应用,通过对系统的硬件和软件设计,能控制交通灯正常的启动和停止。此外,在不同的交通状况下,如交通高峰期和低流期,通过对PLC软件的设计,改变使之相适应的控制方式。选用FX2N-485-BD通信模块,将同一条道路上的信号灯组成一局域网进行统一调度管理,实现5站之间的相互监视和调整,从而可缩短车辆通行等候时间,实现科学化管理。
This paper introduces the application of PLC in crossroads traffic lamp.tt can control the starting and stopping by system hardware and software.In addition,it can change the controlling way by the software according the traffic state.The lamp in the same road can be composed a part network by FX2N-485-BD.It can monitor and adjust each other in the five stations.
