摘要
就如何应用PLC实现十字路口交通信号灯自动控制的设计展开讨论,通过分析对交通信号灯的控制要求,对PLC控制系统进行了软、硬件设计。同时将PLC的逻辑控制、数据运算、数据比较、数据传送通过程序有机的结合起来,既控制交通灯的变化,还有时间显示。
The article is discussed with how to apply PLC to auto-control traffic signal hght. It is software and hardware designing by analysis the control requirements of traffic lights. At the same time, the logic designing made the data arithmetic, data comparison; data transfer pass instruction integrate with PLC programs. Not only does it show the changing of traffic light, but also it displays the time.
