摘　　要：私人车辆数量的不断增长加重了城市的交通压力,如今交通灯已遍及大街小巷。然而传统交通信号灯存在工序复杂、维修不方便、无法联网或通信等问题。PLC控制器在实际应用中具备较好的抗干扰性能,且其故障率低、功能较多,并在不断地更新优化。此外,PLC还具有联网通信功能,多台PLC连接后即可对城市交通进行集体有序控制。由此,文章提出了一种基于PLC控制器的智能交通灯设计方案,利用s7-200PLC控制器进行智能交通灯设计、MCGS组态控制画面,形成了一套集数据监测、交通灯控制与交通疏导的计算机综合管理系统。仿真结果显示该设计具有良好的应用效果。The growing number of private vehicles has increased the traffic pressure on the city,and the traffic lights have spread throughout the streets.However,traditional traffic lights have problems such as complex process,inconvenient maintenance,and inability to network or communication.PLC controller has the advantages of low anti-interference ability,low failure rate and more functions and it is constantly updated.In addition,PLC also has the network communication function,multiple PLC can be connected to the collective orderly control of urban traffic.In this paper,an intelligent traffic light design scheme based on PLC controller is proposed.The s7-200 PLC is used as the controller to design intelligent traffic light and MCGS configuration as the control screen,forming a computer comprehensive management system integrating data monitoring,traffic light control and traffic grooming.The simulative results show that the proposed design has a good application effect.
