PC定时交通信号灯设计

Design of Traffic Timing Signals with Programmable Control

本文提出一种交通控制系统及其设计方法。系统是针对交通控制信号的特点采用日本0MRON公司的SYSMAC·CP型机研制的。此外,文中还分析了控制条件,绘制了控制过程的梯形图,并写出了全部控制程序。这些程序均在试用申证明效果良好,工作可靠,控制灵活。系统的线路简单,操作方便。

This Paper presents a traffic timing control system and its design method. The system based on the characteristics of traffic control signal is developed on system sysma(?).c typa p computer of OMRON company of Japan. Besides, the control conditions of the system are analysized, the trapesoid system is of control process and the computer programs are given. these prsograms tested are effective, reliable and flexible. The circuit system is simple, and the operation of the system is very easeful.
