论文题目 基于 51 单片机的红外遥控的 开关的设计 摘 要 摘 要 本设计是基于红外遥控和 AT89C51 单片机控制的红外遥控开关，这种系统具有很 强的适用性、灵活性、先进性,它的应用大大方便了人们的生活。本文给出了系统的硬 件组成和硬软件设计方法，介绍了解码程序的基本结构和程序框图，为达到准确控制， 将发射脉冲分为连接段、控制段和结束段等 3 部分，并再接收端进行校验。整个系统 由发射和接收两个部分组成。发射部分包括键盘矩阵、编码调制、LED 红外发送器； 接收部分包括 LED 红外光、解调、解码电路。系统在实际实用后，证明其方便、可靠 并具有实用价值。 关键词：AT89C51 芯片；红外遥控开关 I ABSTRACT The design of an infrared remote-control multi-line switch is introduced.This switch is based on principle of infrared remote-control and AT89C51 single chip microcomputer controlling .This system has strong applicability,flexibility and advancement.Peoples life is improved greatly by Its apply. Its system composition and design of hardware and software are presented. The basic structure and chart of control decode program are also expounded. In order to achieve exact remote-control, the transmitted signal is divided into 3 parts:the connecting section, the controlling section and the ending section, then the receiver will verify it.The whole system is composed by the launches partially and the receives partially two parts.Launches partially including the keyboard matrix,the coded modulation,the LED infrared transmitter;Receives partially including the LED infrared light launch,the demodulation,decodes the electric circuit. It was proved that this kind of remote-control is convenient, reliable and practical after using in remote-control system. Key words: the chip of AT89C51; infrared remote-control switch II 目 录 目 录 1 绪 论.....................................................................................................................................1 1.1 课题背景................................
