摘　　要：以三菱FX2N型PLC为控制核心元件,通过对交通十字路口红绿灯时序控制分析,设计开发了基于定时器的自定义时钟脉冲程序段,再以自定义时钟脉冲程序段作为程序基本单元开发设计出十字路口红绿灯的控制程序,程序结构简单、思路清晰,自定义时钟脉冲可以推广应用于解决各种有规律循环变化的时序控制问题。Regarding Mitsubishi FX2N as control core component,and analyzing traffic intersection lights timing control,a custom clock pulse program section based on timer was designed,and which was used as program basic unit to develop traffic intersection lights control program.The program has characteristics of simple structure and clear thinking,which can be applied to solve timing control problems of various regular cycle of changes.
