设计了一种基于AT89S52的家用电器电话远程控制系统,基本原理为AT89S52对振铃次数进行计数,当达到设定的振铃次数后AT89S52控制电话自动摘机,并控制语音提示电路发出提示音,要求输入系统启动密码,然后对密码进行校验,当密码输入正确后,语音提示电路提示输入家用电器控制码,所拨号码经DTMF解码电路解码后,送往AT89S52进行译码,从而控制家用电器。
設計瞭一種基于AT89S52的傢用電器電話遠程控製繫統,基本原理為AT89S52對振鈴次數進行計數,噹達到設定的振鈴次數後AT89S52控製電話自動摘機,併控製語音提示電路髮齣提示音,要求輸入繫統啟動密碼,然後對密碼進行校驗,噹密碼輸入正確後,語音提示電路提示輸入傢用電器控製碼,所撥號碼經DTMF解碼電路解碼後,送往AT89S52進行譯碼,從而控製傢用電器。

A household appliances of remote control system was designed.The design is based on the following basic principles：When somebody calls and ring the phone,The AT89S52 will start to count.When the numbers of the ringing are completed,the telephone will put on automatically,and the language circuit refers in the charge of the AT89S52.At the moment you should put in the system code and inspected it.If the code is right,the language circuit refers that you can put in the controlling code of household appliance.The dialing numbers are deciphered by the deciphering circuit DTMF,and then are decoded by single-chip microcomputer AT89S52.Thus it remote controls the household appliance.
