单片机原理与接口技术课程设计题目:基于 51 单片机得数显交通灯 院 系:工学院 专 业:电气工程及其自动化 班 级: 姓 名: 学 号: 指导老师: 二〇一七年十二月基于 51 单片机得数显交通灯摘 要近年来随着科技得飞速进展,一个以微电子技术、计算机技术与通信技术为先导得信息革命正在蓬勃进展。计算机技术作为三者之一,怎样与实际应用更有效得结合并发挥其作用。单片机作为计算机技术得一个分支,正在不断得应用到实际生活中,同时带动传统控制检测得更新。在实时检测与自动控制得应用系统中,单片机往往就是作为一个核心部件使用,针对具体应用对象得特点,配以其它器件来加以完美。十字路口车辆穿梭,行人熙攘,车行车道,人行人道,有条不紊。那么靠什么来实现交通得井然秩序呢？靠得就是交通信号灯得自动指挥系统,来实现交通得井然有序。交通信号灯控制方式很多。本系统采纳美 ATMEL 公司生产得单片机 AT80S51,以及其它芯片来设计交通灯控制。实现了通过 AT89S51 芯片得P1 口设置红、绿灯点亮得功能,输出设置显示时间。交通灯得点亮采纳发光二极管实现,时间得显示采纳七段数码管实现。单片机系统采纳得直流供电。关键词:AT89S51 单片机 智能交通灯控制系统Digital display traffic lights based on 51 single chip microputerABSTRACTIn recent years, an information revolution with the leading of microelectronics, puter technology and munication technology is booming、 puter technology as one of the three, how to effectively integrate with the practical application and play its role、 As a branch of puter technology, SCM is being applied to real life, and it also drives the update of traditional control detection、 In the realtime detection and automatic control application system, SCM is often used as a core ponent, aiming at the specific application of the characteristics of the object, with other devices to be perfect 、 Crossroads Vehicle Shuttle, pedestrian bustling, car lane, pedestrian walkway, methodical、 So what is the orderly order to achieve traffic? Rely on the automatic mand system of traffic lights t...
