1、摘要隨著電子技術(shù)和自動化技術(shù)的發(fā)展,人們對生活質(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;由手動控制向紅外線遙控、向智能化發(fā)展。此次要設(shè)計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,控制一個220V的可逆、直流電動機(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。
2、除此之外,還要了解單片機(jī)的接口技術(shù)的應(yīng)用和單片機(jī)的抗干擾方法。接口方面主要介紹單片機(jī)的串口??垢蓴_技術(shù)有:指令冗余、攔截技術(shù)、軟件陷阱的設(shè)計、軟件“看門狗”技術(shù)等。關(guān)鍵詞:遙控,紅外線,編碼,抗干擾,智能,串行口38ABSTEACTWiththedevelopmentofelectronictechnologyandautomatictechnology,peoplehavemoreandmorehighexpectationsforlifequality.Thehomeelectricequipmentproductsareinconstantupda
