基于单片机控制的交通信号灯系统设计

基于单片机控制的交通信号灯系统设计摘要随着国家社会经济文化的日益发展，城市交通问题已越来越应引起社会人们共同的共同关注。人、车、路交通三者间关系怎样的综合协调，已日渐成为各级交通和管理服务部门当前需要重点解决处理的三个重要战略问题焦点之一。城市交通计算机控制监测系统则是一个用于处理城市交通数据实时监测、交通信号灯指挥控制管理与路面交通综合疏导控制的大型计算机智能化综合控制管理监测系统，它已是中国现代城市交通监控指挥系统网络中的最基本重要的核心组成的部分。随着中国当今这个社会工业的迅速和发展，汽车产品的平均销售量又有得到了一次很大限度的提高。大量二手汽车产品的高价出售，给了我们老百姓的正常生活工作带给了一种很大限度的经济便利。但是，它本身也无疑给这个城市里的公路交通发展提出去了一种更加复杂严峻现实的新考验。在今天这种发展情况背景下，我们现在除了提出要设计修建一个更加好的公共交通道路管理系统外，还特别需要考虑设计研发出一套更多功能更好智能的自动交通信号灯控制系统。运用智能单片机系统控制各类交通信号灯操作方便，性能更高，易于远程控制。所以，对单片机这一关键课题来进行了一次较系统完整的技术研究或学习，是非常有必要的。在参加本次的毕业设计课题中，我的任务是如何设计一个使用单片机控制的交通信号灯在一个主要十字路口上。系统一共由四部分组成，第一部分是单片机，第二部分是键盘，第三部分是LED灯，第四部分是交通灯和演示系统，满足基本的交通信号灯显示功能，除此之外还包括几个功能，第一个功能是信号灯倒计时功能，第二个功能是时间设置功能，第三个功能是紧急停车情况报警处理功能，第四个是分时段手动调整各种信号灯组合的点亮起始时间以及可根据道路具体行驶情况实施手动停车控制操作等功能。关键词：单片机：交通信号灯DESIGN OF TRAFFIC SIGNAL LIGHT SYSTEM BASED ONSINGLE CHIP COMPUTER CONTROLAbstractWith the increasing development of the country's social economy and culture,theproblem of urban traffic has increasingly aroused the common concern of the society.Thecomprehensive coordination of the relationship among people,vehicles and road traffic hasgradually become one of the three important strategic issues that the traffic and managementservice departments at all levels need to focus on.The urban traffic computer control andmonitoring system is a large-scale computer intelligent integrated control and managementmonitoring system used to process the real-time monitoring of urban traffic data,the commandand control management of traffic lights,and the comprehensive control of road traffic.Themost basic and important core component of the network.With the rapid development of thesocial industry in China today,the average sales volume of automobile products has beengreatly improved once again.The high-priced sale of a large number of second-hand carproducts has brought a great economic convenience to the normal life and work of ourcommon people.However,it has undoubtedly brought a new test of a more complicated andsevere reality to the development of highway traffic in this city.Under the background oftoday's development,in addition to proposing to design and build a better public transportationroad management system,we also need to consider designing and developing a set ofautomatic traffic light control systems with more functions and better intelligence.Using theintelligent single-chip microcomputer system to control all kinds of traffic lights is easy tooperate,has higher performance,and is easy to remote control.Therefore,it is very necessary tocarry out a systematic and complete technical research or study on the key subject ofsingle-chip microcomputer.In participating in this graduation project,my task is how to designa traffic light controlled by a microcontroller at a major intersection.The system consists offour parts in total,the first part is the microcontroller,the second part is the keyboard,the thirdpart is the LED light,the fourth part is the traffic light and demonstration system,which meetsthe basic traffic
