摘要
城市的交通秩序井然有序离不开交通信号灯,一般情况下,十字路口的交通信号灯共有12盏,东西南北每个方向各有红、绿、黄三盏灯,南北方向的信号灯同步工作,东西方向的信号灯同步工作,而且交通灯的变化是有规律可循的。随着我国城市的交通日益繁忙,可以利用PLC来设计十字路口交通信号灯的控制系统,这样可以随时根据交通状况随时调节红绿灯时间,从而大大提高了城市交通效率。我脑子主要介绍了FX2N系列PLC在交通灯控制系统中的应用。
The city＇s traffic order orderly without traffic lights, under normal circumstances, the traffic lights at the crossroads total of 12 East and West each direction red, green, yellow three lights, signal synchronization of the north- south direction , the east-west direction signal synchronization work, and the traffic lights change there is a pattern. With the ever increasing traffic of our city, you can take advantage of the PLC to design the control system of traffic lights at the crossroads, so you can at any time based on traffic conditions at any time to adjust the traffic light time, thus greatly improving the efficiency of urban transport. This paper describes the application of FX2N Series PLC in the control system of traffic lights.
