本科生毕业设计（论文）题目：基于单片机的家用电器电话远程控制姓名：李方舜学号：020700514系别：机械工程及自动化学院专业：机械设计制造及其自动化年级：2007指导教师：（签名）年月日基于单片机的家用电器远程电话控制摘要目前，越来越多的住宅向着智能化，人性化的方向发展。其中家用电器的远程控制正被推广开来。本着低能耗、无污染、使用简单方便的原则。本文设计的是一种基于AT89S51单片机的远程电话控制系统。该系统是以AT89S51为核心、通过现在的个人通信手段，实现基于PLMN(陆基移动通信网)和PSTN(公用电话交换网)的电话远程控制系统。根据CCITT及我国标准共同规定，电话远程控制系统(ITRCS),以PSTN与PLMN通信网作为传输介质,以部分标准程控交换信令(DTMF双音多频信号，振铃信号,回铃音信号等)作为系统控制命令，使用户实现在远端通过移动电话或者固定电话发送DTMF双音多频信号对近端电器设备进行远程控制。本次设计的电话远程控制系统不需要再进行专门的布线,不占用无线电频率资源,从而可避免电磁污染。用户只有输入正确的密码才能控制家电,从而提高了安全性。该系统设计实用，功能灵活多样，可靠性高，操作方便，可以广泛地应用于家庭或者其它场所的智能控制。关键词：AT89S51,远程电话控制,DTMF,智能家电ITheTelephoneRemoteControlSystemforHouseholdElectronicApplianceBaseonTheMicrocontrollerAbstractCurrently,moreandmoreresidentialdeveloptotheintelligenceandhumanity.Amongthem,theremotecontrolofhomeappliancesisbeingpromoted.ResearchfollowstheprinciplesofLowenergyconsumption,pollution-free,easytouse.ThearticledesignedtheremotetelephonecontrolsystemwhichbasedonmicrocontrollerAT89S51.BasingonthePLMNandPSTN,thesystemwhichusesthecorecontrollerSingle-chipmicrocomputerAT89S51realizeslong-distancecontrolhouseholdappliances.Thetelephonecontrolsystem(ITRCS)whichusesthetelephonenetconvertandvoiceinformationreceivesDTMFcodefromthetelephonenet,andinterpretthecode,thecorecontrollercontrolsthestateofhouseholdappliancesrespondedtotheinterpretation.Longdistancecontroloftelephonedoesnotrequirespecialwiresdistributionanddoesnottakeupwirelessfrequencyresources.Electromagneticpollutioncanthusbeavoided.Thedesigningofasystemoflong－distancecontrolbasedonsoundprocessingtechnologyandDTMFdecodingtechnologyispresentedinthispaper.Onlythroughinputtingthecorrectpasswordtocontrolthem,theuserscancontroltheconditionofhouseholdelectricalequipment,sothesystemsecuritycanbeimproved.Thissystemispractical,andthefunctionisflexible,andtheoperationisconvenientwithhighreliability,whichcanbeusedextensiveinvariouskindsofcontrolequipmenttohomeandothersfield.Keywords：AT89S51,Telephoneremotecontrol,DTMF,HouseholdappliancesII目录摘要...................................................................................................................................................IAbstract............................................................................................................................................II第一章绪论.....................................................................................................................................11.1本课题研究的背景............................................................................................................11.2远程控制的内容................................................................................................................2第二章系统设计可行性分析..........................................................................................................32.1总体设计分析........................................
