摘　　要：为保障交通安全有序,减少交通事故的发生,需要在交通路口设计交通灯控制系统。由于PLC控制系统具有修改方便、操作简单、易上手的特点,本文综合运用PLC定时器指令、计数器指令、转换指令、比较指令等实现交通信号灯的控制程序设计。结果表明,该程序能够稳定可靠地实现十字路口交通灯的多模式控制。To ensure traffic safety and order,and reduce the occurrence of traffic accidents,it is necessary to design a traffic light control system at traffic intersections.Due to the characteristics of convenient modification,simple operation,and ease of use of the PLC control system,this paper comprehensively uses PLC timer instructions,counter instructions,conversion instructions,comparison instructions,etc.to achieve the control program design of traffic signal lights.Results indicate that the program can stably and reliably achieve multi-mode control of traffic lights at intersections.
