基于单片机的智能交通灯控制系统 作者姓名：龙 攀 专业名称：通信工程 指导老师：陈明明 讲师 摘要 交通控制系统是近现代社会随着物流、出行等交通发展产生的一套独特的公共管理系统。要保证高效安全的交通秩序，除了制定一系列的交通规则，还必须通过一定的科技手段加以实现。交通灯是城市的重要指挥系统，与人们的日常生活密切相关。随着世界经济的迅速发展，车辆也随之越来越多，所以交通拥挤与安全等一系列问题也变得很重要。 而如今我们的社会已经进入到一个飞速发展的社会，所以在对于人越来越多，车越来越多的世界，我们更加需要的是一种安全感，需要一种智能化的时代的到来。交通安全更加是我们应该去关注的一个问题。 而本论文则是研究一种基于AT89C52单片机芯片的交通灯信号控制系统，有着许多功能模块组成。实现了十字路口的智能交通灯控制。而我利用Proteus与Keil来可以对此交通灯控制系统进行仿真。通过仿真本设计能模拟出基本的控制系统还能进行倒计时显示，可以检测道口流量，并且可以根据流量大小改变红绿灯的显示时间，有效地实现了智能交通灯的控制。 该系统能够简单有效地疏导交通，提高交叉口的通行能力，实现智能交通灯控制，提高交通安全，减少交通事故。该系统同时也拥有结构简单、可靠性高、成本低、实时性好、安装维护方便，并且具有良好的扩展完善特点有广泛的前景。并且这也是解决城市交通的一种很不错的系统。 关键词 ：单片机 交通灯 控制系统 Proteus Keil Abstract Traffic control system is a modern society with logistics, travel and other transportation development produce a unique set of public management system. To ensure the efficient and safe traffic order, in addition to formulate a series of traffic rules, still must pass a certain technological means to achieve them. The traffic light is an important command system of city, is closely related to Peoples Daily lives. With the rapid development of world economy, the vehicle has been more and more, so a series of problems such as traffic congestion and safety also becomes very important. Today, our society has entered into a rapid development of society, so more and more people are in for, car more and more of the world, we need more is a kind of sense of security, need a kind of intelligent era. More traffic safety is a problem we should pay attention to. While this paper is to study a kind of traffic signal control system based on single chip microcomputer AT89C52 chip, has many function modules. Implements the intersection of intelligent traffic light control. And I can use Proteus Keil to traffic light control system simulation. Through the simulation of this design can simulate the basic control system also can countdown display, can detect crossing traffic, and can change according to the volume of traffi
