摘要
    本次毕业设计设计了基于单片机的红外遥控开关，论文首先介绍了系统的总体组成，然后分为硬件与软件两部分进行阐述。硬件电路部分主要描述了红外接收主控制模块与各模块的相互关系，这部分主要采用MC-51作遥控发射器及接收处理器。该系统在实际使用后，证明其方便、可靠并具有实用价值。
    课题涉及到硬件与软件两大部分，硬件电路部分的实现是以单片机AT89C2051为核心，作为主控制电路，其他外围电路为从属电路部分。把硬件电路可分为两个模块，控制编码模块与发射模块，再把遥控模块分为三个小模块：单片机主控，红外接收模块和电源部分。软件部分设计步骤可分为：主程序和中断程序入口程序、初始化程序中的各变量、主程序、键盘工作子程序、中断接收程序、延时子程序等。该论文就上面问题详细介绍了软硬件设计、实现和调试过程中所采用的方法,并采取相应的步骤解决问题。

Abstract
    This graduation project based on monolithic integrated circuit's infrared remote control switch, the paper first introduced system's main assembly, then divides into the hardware and the software two parts carries on the elaboration. The hardware circuit part mainly described the infrared receive master control module with the various modules reciprocity, this part mainly uses MC-51 to do controls remotely the launcher and the receive processor. This system after actual use, proved that its convenient, reliable and has the use value. the topic involves to the hardware and the software two major parts, hardware circuit part realization is take monolithic integrated circuit AT89C2051 as a core, takes the master control electric circuit, other peripheral circuit to be subordinated the electric circuit part. May divide into two modules the hardware circuit, the control code module and the launch module, divides into again the remote control module three small modules: Monolithic integrated circuit master control, infrared receive module and power unit. The software part design procedure may divide into: Master routine and in interrupt routine entry program, initialization routine various variables, master routine, keyboard work subroutine, interrupt receive procedure, time delay subroutine and so on. This paper introduced in detail on the above question the software and hardware design, realizes the method which uses with the debugging process, and adopts the corresponding step to solve the problem.
