基于CPAC的智能交通信号灯的设计

交通信号灯是城市道路交通网中的主要控制设施，以往的交通信号的控制多半采用单片机，PLC控制，开发过程繁琐，兼容性不好。基于计算机可编程自动化控制器CPAC，采用ST语言作为主程序开发语言，完成了智能交通灯系统程序编写，设计出了系统的可视化界面，完成了系统硬软件的结合。从实验结果来看，系统具有较好的稳定性和准确性，能够进行上时间的无错运行。

Design of Intelligent Traffic Lights Based on CPAC

Traffic lights are the major control facilities in the urban road traffic network, the control of the traffic signal in the past mostly uses the low-compatibility single chip microcomputer PLC, which requires a complex development process. Based on CPAC (computer programmable automation controller), the paper involves completing programming for the intelligent traffic light system with the ST language as the main programming language, designing a visual interface for the system, and combining the systematic hardware and software. The experimental results indicate that the system has good stability and accuracy thus allowing error-free operation for a long period of time.
