单片机课程设计报告 题 目 交通灯设计 学 院 电子信息工程 专 业 电子信息工程 班 级 11统本电信01班 学 号 111102010136 学生姓名 全海松 指导教师 董昌孝 成 绩 前言 交通灯做为一种信号指示灯，自它诞生以来就一直与社会的发展息息相关。最初的交通灯只有红绿两种灯，再后来人们发现两盏灯之间的切换太快，具有不可预测的危险性，于是后来在红灯和绿灯之间加上了一盏黄灯，做为时间转换的一个缓冲。现代的交通灯已经做到智能化控制，为我们的出行带来了极大的便利，他已经成为交通指挥平台中不可替代的重要工具。 本次实训采用MSC-51系列Preface The traffic lights as a signal indicating lamp, since its inception has been closely linked with development of the society. Initially only red and green traffic lights two lights, two lights and later it was discovered that switching between too fast, dangerous and unpredictable, so later in between the red and green with a yellow light, as a buffer time conversion. The traffic lights have been done in modern intelligent control, which brought great convenience for our trip, he has become an important tool for irreplaceable traffic command platform. The training of the MSC-51 series AT89C51 microcontroller simulation design of the traffic light, using SCM interrupt system in case of emergency, using LED simulation of traffic signal lamp. The main contents include the simulation and debugging. The simulation using keil and Protues software simulation, debugging using PCB board debugging. In the training before should have 51 MCU, digital circuit, analog electronic circuit knowledge and assembly language programming ability. Hope that through the development process and the assembly language to design the experiment to further understand the microcontroller, for future work to lay a certain foundation, cultivating the ability of solving problems independently, cultivate the team cooperation ability. 目录 第一章 基础部分 - 5 - 一、基础项目设计要求 - 5 - 二、设计方案 - 5 - （1）总体方案图 - 5 - （2）方案说明 - 5 - 三、硬件设计 - 10 - 1、元件清单 - 11 - 四、软件设计 - 11 - 1、设计流程图 - 11 - 五、仿真与调试 - 12 - 第二章 拓展部分 - 16 - 一、拓展说明 - 16 - 二、方案论证 - 16 - （1）供电方案 - 16 - （2）倒计时方案 - 16 - （3）按键输入方案 - 16 - （4）主控电路 - 16 - 三、方案设计 - 16 - （1）方案框图 - 16 - （2）电路说明 -
