基于单片机的智能交通控制系统设计摘要随着人们收入的增加,车辆的数量也在逐年增加。车辆的增多给交通带来了巨大的压力。城市交通拥堵随处可见,拥堵最为严重的区域就是各地区三岔口和十字路口。为了节省人们的时间,使用智能交通控制系统已迫在眉睫。本文在基于单片机对于智能交通灯控制系统的研究与设计,提出了解决当前交通拥堵的问题,进而提出实现高效的交通通行设计。单片机通过定时器控制红绿灯的亮灭时间,使交叉口通行畅通。该交通灯控制系统选用了AT89C51单片机作为控制芯片,提高了交通灯的智能性、可靠性和实用性。理论证明本系统能简单、经济、有效地疏通交通,提高交叉口的通行能力,最大限度的提高路口车辆的行驶速度。关键词:AT89C51单片机、智能交通灯、倒计时AbstractAs people's incomes increase,the number of vehicles is increasing year by year.Theincrease in vehicles puts a huge strain on traffic.Urban traffic congestion is everywhere,and themost congested areas are the three forks and intersections in various regions.In order to savepeople's time,the use of intelligent traffic control systems has become imminent.Based on the research and design of the intelligent traffic light control system of thesingle-chip microcomputer,this paper proposes to solve the current traffic congestion problem,and then proposes to achieve efficient traffic traffic design.The single-chip microcomputercontrols the light on and off time through the timer to make the intersection flow smooth.Thetraffic light control system uses AT89C51 single-chip microcomputer as the control chip,whichimproves the intelligence,reliability and practicality of traffic lights.Theoretical evidence shows that this system can simple,economical and effective trafficdredging,improve the traffic capacity of intersections,and maximize the driving speed ofvehicles at intersections.Key Words:AT89C51 MCU,intelligent traffic light,countdown目录摘要Abstract绪论课题的背景和意义国内外研究现状…单片机简介.3单片机的发展历史3单片机的发展趋势.4单片机的特点..6单片机的基本结构…7智能交通灯控制系统的总体设计.9智能交通灯设计的基本要求.9智能交通灯通行方案的设计…。.9智能交通灯控制系统的功能要求o智能交通灯的基本构成及原理10智能交通灯硬件的设计.12智能交通控制系统硬件电路构成及原理.........12智能交通控制系统电源电路12智能交通控制系统晶振电路12智能交通控制系统复位电路13智能交通控制系统显示电路13智能交通控制系统按键控制电路14智能交通控制系统总电路.14智能交通灯软件的设计…,44444444444444444444444444444,软件设计应用环境..15
