摘　　要：本文基于可编程逻辑控制器的链接(PLC-Link)通信功能,设计了一个城市道路交通信号控制系统。该系统能对三个交叉口的交通信号灯进行集中、独立和绿波控制,具有在线修改信号配时参数和监视信号灯运行状态的功能。系统为主站PLC配置了触摸屏,系统的所有操作都在触摸屏上进行,便于管理人员对区域内交叉口信号灯的远程控制。文章以三台松下AFP-XC30R型PLC链接为例,介绍了系统的设计过程,论述了系统PLC控制程序的设计步骤,介绍了PLC与触摸屏组合应用及触摸屏界面的制作方法。系统已在实验室调试通过。该系统的设计为进一步研制实用的交通信号区域控制系统奠定了基础。Based the communication function of Programmable Logic Controller （PLC-Link）, the paper has designed a traffic signal control system with PLC-Link which can realize centralized or independent or green wave control to three signalized intersections , and can change signal timing pararneters on line and also can display live state of traffic lights. With configured touch panel to NO. 1 PLC, the system can do all operations on touch panel, which is convenient for manager to control long-distance signalized inter-sections within the control region. Take three Panasonic AFP-XC30R PLCs link system as example, the paper has introduced the design process, the design steps of PLC control program and making method of touch panel interface. The system bas been running successfully in the lab. The study of the paper establishes foundation to further develop applied traffic signal region control system.
