基于 PLC的智能交通控制系统设计毕业论文基于 PLC 的智能交通控制系统设计摘要随着社会经济的发展， 城市交通问题越来越引起人们的关注，我国许多大中城市的交通压力都非常大。 所以，改善与提高现有的交通系统的工作效率，加强交通路口的信号灯控制和监控是非常重要的。矚慫润厲钐瘗睞枥庑赖。解决好交通信号灯控制问题将是保障交通有序、安全、快速运行的重要环节。 但现有的交通信号灯控制系统都是单一的固定时序控制, 不能够根据实际交通状况进行调节控制。 聞創沟燴鐺險爱氇谴净。本文主要使用 PLC和地感线圈来实现智能交通控制。在十字路口相应的位置埋设地感线圈， 对此路段上的车流量进行统计，并根据车流量的变化， 改变绿灯的控制时间，可以实时地对绿灯资源进行合理调配，提高十字路口的通行能力， 缓解交通拥挤，达到最优控制。 文中详细介绍了系统的硬件设计和软件设计，最后用 iFIX 工程组态软件进行监控，达到了比较满意的可视化效果，并实现了模拟真实环境的目的。残骛楼諍锩瀨濟溆塹籟。关键词智能交通地感线圈车流量延时控制基于 PLC的智能交通控制系统设计THE DESIGN OF INTELLIGENT TRAFFIC CONTROL SYSTEM BASED ON PLC酽锕极額閉镇桧猪訣锥。ABSTRACT Along with the development of the society economy, the city transportation problem causes our concern more and more, and traffic pressure in many large and medium-sized cities in China is very great. Therefore, to improve and enhance efficiency of the existing transport system, strengthen the control of traffic lights and monitor the situation is very important.彈贸摄尔霁毙攬砖卤庑。The traffic light control is important for urban traffic safety and high efficiency. But all the traffic light control are working in standing sequence, and are unable to make adjustment with different traffic flow. 謀荞抟箧飆鐸怼类蒋薔。In the design of the paper, one method of the intelligent traffic control is used which combines the PLC and the induction coil. Induction coils are preburied at the correspond- ing crossroads to make statistics of the veh...
