基于单片机的交通灯设计 摘 要 交通信号仿真过程是一个对交叉口控制的模拟过程，交通信号仿真机可让人们直观的认识交通信号的参数。在交通工程教学中，能够用交通信号仿真机来展示给学生，更是能够收获到很好的效果。 本文介绍了利用STC89C52单片机设计制作交通信号灯。包括硬件电路板的设计，控制主程序的编写与仿真。利用LED灯做为信号灯的仿真，利用数码管来进行倒计时显示。本文设计首先采使用KEIL对主程进行C语言编程，然后使用proteu与KEIL进行联机对信号灯主程序进行调试，最后使用protel99对电路原理图进行绘制。 关键词：交通信号灯、单片机、proteus、protel 99 Abstract Traffic signal simulation process is an intersection control simulation process, traffic signal simulator allows people have the direct-viewing understanding traffic signal parameters. In traffic engineering teaching, teacher use the traffic signal simulator to show students may take a good effect. This paper describes the HYPERLINK app:ds:technologicaltechnological HYPERLINK app:ds:processprocess of design a traffic signal simulator based on STC89C52 single-chip design . Include hardware circuit board design, writing the main program and simulation. Use leds as light ，using digital tube for countdown show. The paper presents the design of the main program based on the C programming language in software KEIL at first, then use the proteus simulation and debugging the main program of the lights. finally use the protel DXP draw for circuit principle diagram, while generating PCB（Printed Circuit Board）figure. Key words: traffic signal simulator, microcontroller, keil,proteus, protel DXP 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc371448043 第一章 绪论 PAGEREF _Toc371448043 \h - 1 - HYPERLINK \l _Toc371448044 1.1 交通信号灯研究的背景及意义 PAGEREF _Toc371448044 \h - 1 - HYPERLINK \l _Toc371448045 1.2 交通信号灯介绍 PAGEREF _Toc371448045 \h - 1 - HYPERLINK \l _Toc371448046 1.3 论文研究的目的和内容 PAGEREF _Toc371448046 \h - 1 - HYPERLINK \l _Toc371448047 第二章 硬件选型 PAGEREF _Toc371448047 \h - 3 - HYPERLINK \l _Toc371448048 2.1 单片机知识 PAGEREF _Toc371448048 \h - 3 - HYPERLINK \l _Toc371448049 2.1.1 单片机简介 PAGEREF _Toc371448049 \h - 3 - HYPERLINK \l _Toc371448050 2.1.2 单片机发展概述 PAGEREF _Toc371448050 \h - 4 - HYPERLINK \l _Toc371448051 2.1.3 单片机的应用 PAGEREF _Toc371448051 \h - 5 - HYPERLINK \l _Toc37
