文档介绍：本科毕业设计题目单片机红外遥控系统设计院(系部) 河南理工大学万方科技学院专业名称电气工程及其自动化年级班级电气 12—3班学生姓名指导教师 2016 年4月 20日河南理工大学万方科技学院本科毕业论文 I 摘要随着人们生活水平越来越好, 人们的日常生活中出现了许多有益的远程遥控程序。以前做工简单的遥控器使用特有的遥控编解码电路,但因为功能键及性能的限制,只有某些特定的领域才能使用。而使用单片机有可以实现远程控制程序,方便编程,可以自由设置操作码的优点。这个设计主体特别采用了AT89C5 1单片机,综合采用了单片机中断系统、定时器、计数器等知识, 采用红外光的特长,编写一个红外遥控系统。这个系统包含了发送和接收两部分,应用程序的编码/ 解码芯片来控制操作。发射方面包含键盘矩阵、编码调制、 LED 红外线发射器;接受部分包含红外接收芯片、光电转换器、调解电路。其优势是拥有简短的硬件电路,软件功能完善,更好的性价比优势,有一定的应用和参考价值。关键词: 单片机 AT89C51 ;LED 红外发射器河南理工大学万方科技学院本科毕业论文 II Abstract With promotion of humanistic, scientific progress and people living standard rise slowly, all conducive to life of the remote control system began to stride the lives of people. Previous remote control remote coding and decoding the special integrated circuit using the, this approach, while work is simple easy, but as a result of function key number and function by the constraints of the special applies only in the use of some special electrical products, service areas affected. And the use of single-chip design in the use of remote control system, with programming is flexible, set arbitrary and advantage of operation code number. This design adopts AT89C51 micro-controller as the main body, using bination of MCU interrupt system, timer, counter and other knowledge, using infrared expertise, to prepare a infrared remote control system. The system includes transmitting and receiving part, application coding / decoding chip to control the operation. Emission including matrix keyboard, modulation and coding, LED infrared emitter; acceptance Part contains infrared receiving chip, photoelectric converter, the mediation circuit. The advantages of the hardware circuit is simple, software function, cost-effective and other advantages, 河南理工大学万方科技学院本科毕业论文 III have certain application and reference ability.
