摘要摘要：随着我国社会经济的不断发展，交通问题已成为一个不容忽视的突出问题。随着我国人口压力的不断加大，现代化需求的加剧，城市化的日益扩大，交通是否便利是衡量我国城市生活水平和投资环境的重要指标之一。我国大部分交通信号系统都采用了定时控制系统。然而，由于其低交通效率和交通拥挤，本文以 PCL 技术为研究重点，旨在研究和设计一种基于 PCL 技术的有效的交通控制信号灯系统。该系统可以改善交通信号控制系统，特别是拥挤的交通信号控制系统，维护行车秩序和安全。关键词：PLC；交通信号灯；控制共 页 第 页 ABSTRACTAbstract:With the continuous development of China's social economy, the traffic problem has become a prominent problem that can not be ignored. As China's population pressure continues to increase, the demand for modernization intensifies, and urbanization expands day by day, one of the most important evaluation indexes of urban living standard and investment environment in China is whether the transportation is convenient or not. The timing control system is used in most of the traffic signal systems in China. However, due to its low traffic efficiency and traffic congestion, this paper focuses on PCL technology and aims to study and design an effective traffic control light signal system based on PCL technology. This system can improve the traffic signal control system, which is especially crowded, and maintain the order and safety of travel.Keywords: PLC; Traffic lights; control共 页 第 页 目 录中文摘要..............................................................................................................1ABSTRACT.........................................................................................................2目 录.....................................................................................................................3第一章 绪论.............................................................................
