1、木文设计的是一种基于AT89C51单片机的远程电话控制系统。该系统是以AT89C51为核心、利用现有的个人通信终端,实现基于PLMX(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。电话远程控制系统(ITRCS),以CCITT(国际电报电话咨询委员会)及我国标准共同规定的部分标准程控交换信令(DTMF双音多频信号,振铃信号,冋铃音信号等)作为系统控制命令,以PLMN与PSTN通信网作为传输介质,使用者可以在远端利用固定电话或移动电话发送DTMF双音多频信号,实现对近端电器设备的实时远程控制。该电话远程控制系统不需进行专门的布线,不占用无线电频率资源,从而可避免电磁污染;且
2、通过嵌入式的智能语音提示,突出的语音提示功能和密码控制系统,可使操作者根据各种提示音及吋了解受控对象的有关信息。还可通过发出语咅命令用电话远程控制多个受控对象,用户可以查询其状态,提供密码处理功能,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AT89C51;远程电话控制;DTMF;智能家电TheTelephoneRemoteControlSystemforHouseholdElectronicApplianeeBaseonTheMicrocontrollerAbstractThear
