摘要随着科学技术的飞速发展,汽车的数量与日俱增,与此同时城市交通阻塞问题已经成为一个国际化的问题。交通控制系统虽然在某种程度上可以满足简单指挥交通的需要,但有着明显的缺点,即有相对固定的红绿灯时间,不能随着车流量的改变实时的提哦正红绿灯的显示时间。为保证安全快捷的交通秩序,除了要制定一些必要的交通规则,还要通过一定的科技手段使其优化。根据交通灯在实际生活中的需求特点,本文结合8051单片机核心的控制功能,设计了依据单片机来控制交通灯的基本方法,其中设计中包括车流量检测,紧急处理,时间显示设置,LED倒计时等必要的功能。根据道路上的交通情况实时的对道路的红绿灯进行调控,减少交通路口的车辆堵塞,并进行故障检测功能,最大程度上保证更加的智能化,实用性和可靠性,最大化的满足当今社会对交通系统的更大需求。40632

Abstract With the rapid development of science and technology, the number of cars at the same time the traffic congestion problems grow with each passing day, the city has become an international problem. Although the traffic control system in a certain extent can meet the need of simple direct traffic, but there are obvious shortcomings, which have relatively fixed red time, not with the traffic flow changes in real-time display of time. Red light. In order to ensure safe and efficient traffic order, in addition to the development of some of the necessary traffic rules, but also through a certain scientific and technological means to optimize the. According to the demand characteristics of traffic lights in real life, the control function with the 8051 microcontroller core, a basic design method for single chip microcomputer to control traffic lights, which are designed to include traffic detection, emergency handling, time display settings, LED countdown and other necessary functions. According to the regulation on the road traffic situation in real time on road traffic, reduce traffic intersection traffic jams, and the fault detection function, the maximum extent to ensure more intelligent, practicability and reliability, the maximum to meet the growing demand for transportation system.
