1、 本科生毕业论文(设计)多用途无线遥控器设计院系名称姓名学号专业指导教师年4月26日 摘 要如今,利用红外遥控传输较小的数据量来控制电器设备的应用已经非常广泛,对各种红外遥控器发出来的红外编码进行采集和处理就成了众人非常关心和急需解决的问题。仔细分析了多种遥控器所发红外编码的特点及其规律,详细地阐述了利用单片机系统对家用电器遥控器发出来的红外编码进行学习、存储、传输和再生的原理,来实现以红外线为传送信息媒介的短距离红外遥控控制电路,具有准确度高、速度快的特点。在了解了其发射的编码脉冲信号波形后,设计了基于单片机的红外遥控器解码器,对解码器硬件和相应软件进行分析并给出程序流程图,给出多功能遥控系
2、统框图,详细地说明其硬件组成原理和各个部分的功能,并给出了部分程序流程图。本设计以单片机为核心设计一种红外线遥控系统,可以对各种红外线遥控器发射的信号进行识别、存贮和再现等功能,从而实现对各类家电的控制。关键词:红外遥控器,单片机,编码,解码,信号 IVABSTRACTToday, the application, using infrared telecontrol to transmit a few data to control electric equipment, is so popularized. The problem, picking and processing the i
3、nfrared code which sent by the various telecontroller, being watched out and solved eagerly by many people. We analyzed carefully the characteristic and its law of the infrared code which sent by the kinds of telecontroller. The principle, using the singlechip system to learn, store, transmit and re
4、store the infrared code which sent by the telecontroller of electric appliance, is also detailedly expounded in this paper. By guiding of the principle, which take the infrared as the pass-along message medium short distance wireless remote control circuit, which has the accuracy to be high, the spe
5、ed quick characteristic. After thecode pulse signal waveshape that infrared remote controller emits is known, the decoder of infrared remote controller based on single chip microcomputer is designed, the decoder hardware and appropriate software are analysed and the program process diagrams are give
6、n. The paper puts forward frame diagram of multifunction remote control system and detailed the compose of hardware principle and function of each part, and gives part of program flu diagrams. This is to design an intelligent infrared remote focusing on single chip. It can distinguish, store and rec
7、urrence to signals that all kinds of infrared remote launched. Thereby, the control of all household electrical appliances can be realized.Key words: infrared remote controller;single chip microcomputer;code decoder;signal目 录摘 要IABSTRACTII第1章 绪论11.1 研究背景11.2 研究目的11.3 研究意义2第2章 系统分析32.1 设计要求32.1.1 整个控
