1、摘要隨著電子技術(shù)和自動(dòng)化技術(shù)的發(fā)展，人們對(duì)生活質(zhì)量的要求越來越高。家用電器產(chǎn)品也在不斷的更新?lián)Q代。從始初的晶體管、到電子管；由模擬到數(shù)字；由分立元件到集成電路；從普通向高性能、多功能型；由手動(dòng)控制向紅外線遙控、向智能化發(fā)展。此次要設(shè)計(jì)的就是紅外遙控窗簾。它是采用89C2051單片機(jī)的最小系統(tǒng)設(shè)計(jì)，控制一個(gè)220V的可逆、直流電動(dòng)機(jī)控制窗簾的拉開和關(guān)閉。紅外遙控的重點(diǎn)就在紅外發(fā)送和接收及編碼與解碼問題。所以討論的重點(diǎn)也就是這些個(gè)方面。當(dāng)今專用的紅外發(fā)送和接收器件非常多，編碼與解碼的方法也很多，所以要根據(jù)實(shí)際的情況來選取合適的發(fā)送、接收器件和編碼、解碼方法。除此之外，還要
