摘要: 现代社会发展使得交通运输日益重要,交通灯已经与我们日常生活密不可分。传统交通灯控制系统在某种程度上虽然可以实现十字路口交通指挥作用,但不能根据实际道路车流量调节交通灯显示时长,导致道路拥挤情况严重。32987
本文在深入调查城市道路上各时段车流量特点的基础上,设计了一种新的智能化交通灯控制系统。它根据DS1302时钟芯片提供的时间信息来判断车流量,采用51单片机控制不同时段交通灯的显示时长,来缓解交通堵塞状况。
本文制定了交叉路口的交通灯规则,完成了硬件电路的设计,并用软件编程进行了仿真,最后焊出了硬件电路板,并调试成功。 毕业论文关键词:智能交通控制;AT89C51;定时控制;DS1302
Intelligent Traffic Light Control
Abstract: With the development of modern society, transportation is becoming more and more important, and the traffic light has been closely related to our daily life. In a certain extent, traditional traffic control system although can realize the intersection traffic command role, but can’t adjust the traffic lights’ display according to the actual traffic flow, resulting in the road congestion situation is serious.
This paper designs a new intelligent traffic light control system based on the characteristics of traffic flow in each time period of city road.. According to the time information provided by the DS1302 clock chip, it can judge the traffic flow, and use 51 single chip microcomputer to control the time of the traffic lights in different periods, to ease the traffic jam.
In this paper, the rules of traffic lights at intersections are formulated, the hardware circuit is designed, and the software is programmed. The hardware circuit board is welded and debugged successfully.
