摘要随着电子技术和自动化技术的发展，人们对生活质量的要求越来越高。家用电器产品也在不断的更新换代。从始初的晶体管、到电子管；由模拟到数字；由分立元件到集成电路；从普通向高性能、多功能型；由手动控制向红外线遥控、向智能化发展。此次要设计的就是红外遥控窗帘。它是采用89C2051单片机的最小系统设计，控制一个220V的可逆、直流电动机控制窗帘的拉开和关闭。红外遥控的重点就在红外发送和接收及编码与解码问题。所以讨论的重点也就是这些个方面。当今专用的红外发送和接收器件非常多，编码与解码的方法也很多，所以要根据实际的情况来选取合适的发送、接收器件和编码、解码方法。除此之外，还要了解单片机的接口技术的应用和单片机的抗干扰方法。接口方面主要介绍单片机的串口。抗干扰技术有：指令冗余、拦截技术、软件陷阱的设计、软件“看门狗”技术等。关键词：遥控，红外线，编码，抗干扰，智能，串行口ABSTEACTWiththedevelopmentofelectronictechnologyandautomatictechnology,peoplehavemoreandmorehighexpectationsforlifequality.Thehomeelectricequipmentproductsareinconstantupdatetoo.Fromthetransistorofthebeginningofbeginning,totheelectrontube;Imitatedittothefigure;Fromthediscretecomponenttotheintegratedcircuit;Fromordinarytohighperformance,multi-functionaltype;Bymanualtocontroltoinfraredrayremotecontrol,tointelligenttodevelop.Thisonethatdesignedlessimportantisaninfraredremotecontrolcurtain.Itadoptminimumsystem,89C2051ofMCUdesign,controlone220Vreversiblechangingspeedthemotorcontroltodrawbackandshutoffthecurtain.[27]Infraredfocalpointofremotecontrolininfraredtosendwithreceivingandcodeanddecodetheissue.Sofocalpointthatdiscussthe.Aspecial-purposeoneinfraredtosendandreceivedeviceverymore,codeandmethodthatdecodetooalotofnowadays,sowillchoosesuitablesending,receivingthedevice,code,decodingmethodaccordingtotherealsituation.Inaddition,shouldunderstandtheapplicationoftheinterfacetechnologyoftheone-chipcomputerandone-chipcomputeranti-interferencemethod.Interfacerespectintroducesoneclusterofmouthsoftheone-chipcomputermainly.Anti-interferencetechnologyisasfollows,orderredundancy,interceptiontechnology,design,software,softwareoftrap“guardthegatedog"technology,etc.Keywords:Remotecontrol，Infraredray，Code，Anti-interference，Intelligence，Serialmouth目录TOC\o"1-2"\h\z\uHYPERLINK\l"_Toc106548927"摘要PAGEREF_Toc106548927\hIHYPERLINK\l"_Toc106548928"ABSTEACTPAGEREF_Toc106548928\hIIHYPERLINK\l"_Toc106548929"1绪论PAGEREF_Toc106548929\h1HYPERLINK\l"_Toc106548930"2概
