摘要
    本次畢業(yè)設(shè)計設(shè)計了基于單片機(jī)的紅外遙控開關(guān)，論文首先介紹了系統(tǒng)的總體組成，然后分為硬件與軟件兩部分進(jìn)行闡述。硬件電路部分主要描述了紅外接收主控制模塊與各模塊的相互關(guān)系，這部分主要采用MC-51作遙控發(fā)射器及接收處理器。該系統(tǒng)在實際使用后，證明其方便、可靠并具有實用價值。
    課題涉及到硬件與軟件兩大部分，硬件電路部分的實現(xiàn)是以單片機(jī)AT89C2051為核心，作為主控制電路，其他外圍電路為從屬電路部分。把硬件電路可分為兩個模塊，控制編碼模塊與發(fā)射模塊，再把遙控模塊分為三個小模塊：單片機(jī)主控，紅外接收模塊和電源部分。軟件部分設(shè)計步驟可分為：主程序和中斷程序入口程序、初始化程序中的各變量、主程序、鍵盤工作子程序、中斷接收程序、延時子程序等。該論文就上面問題詳細(xì)介紹了軟硬件設(shè)計、實現(xiàn)和調(diào)試過程中所采用的方法,并采取相應(yīng)的步驟解決問題。

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.
