摘要

摘要：本论文简单地介绍了红外线遥控发射和接收系统原理，在文中给出了MCS89C51作为遥控接收系统和作为发射系统的重要位置，以及完整的51汇编程序代码和MCS89C51的各种功能简介，尤其是它在作为红外线遥控系统中几个重要的方面如中断、定时器和其与键盘的连接方面作了更详尽的介绍。本文中包括红外线发射和红外线接收的原理图，并给出多种方案。还对红外线遥控的发送程序、红外线接收程序、定时中断程序、发送周期程序、发送数据程序和发送“0”和“1”等程序进行了编制。另外对各种程序的流程图进行了绘制，从而较全面地完成此设计的要点，参考流程方框图的构思过程，就可以编写应用软件，便是本论文的特点。利用MCS89C51多次发送及反码校验功能，防止了其它遥控码和未知代码的干扰，从而提高了产品的可靠性。又由于红外线遥控装置具有体积小，功耗低、功能强和成本低等特点,是现代日常生活中一种重要的遥控设备,因此也是本次作为设计课题的重要理由之一。

关键词：MSC89C51、红外线遥控、键盘接口。

Summary

summary : And acception system principle that this thesis has recommended infrared remote-control command to launch briefly, provide MCS89C51 as the acception system of remote control in the article and as the important position that launch the system, and brief introduction of 51 intact assembler codes and various functions of MCS89C51, especially until several important respect such as cut off , timer and their make more exhaustive introduction with connection of keyboard as infrared remote-control command system it. Include the principle picture that the infrared ray was launched and the infrared ray received in this text, provide many kinds of schemes. Procedure of sending still to infrared remote-control command, infrared ray receive procedure , cut off procedure , send cycle procedure , send data procedure and send " 0 " and " 1 " ,etc. procedure go on , make regularly. In addition has drawn various flow diagrams of procedure , thus finish this main point designed in an all-round way, consult the plot course of the procedure block-diagram, can write the application software , it is a characteristic of a thesis. Utilize MCS89C51 send and yards of check-up function instead many times , prevent other remote control yard and unknown interference of code from, thus improved the dependability of the products. Because again because the infrared remote-control command device is small, low power dissipation , function are strong with the low grade characteristic of the cost, it is a kind of important remote control apparatus in modern daily life, so regarded as one of the important reasons for designing the subject this time
