摘 要
本課題主要研究單片機實現(xiàn)遠程電話控制家用電器。系統(tǒng)以單片機AT89C51和雙音多頻解碼集成電路MT8870為核心，通過電話線路遙控的遠程電話控制系統(tǒng)。該系統(tǒng)實用、功能靈活多樣，可以對被遙控對象的狀態(tài)進行查詢以及控制，可以廣泛的應(yīng)用于家用電器或者其它場所的各種控制設(shè)備。該系統(tǒng)通過嵌入式的智能語音提示, 突出的語音提示功能和密碼控制系統(tǒng), 可使操作者根據(jù)各種提示音及時了解受控對象的有關(guān)信息。系統(tǒng)可實現(xiàn)通過發(fā)出語音命令用電話遠程控制多個家電, 用戶可以查詢家電狀態(tài), 提供密碼功能, 只有輸入正確的密碼才能控制家電, 從而提高了安全性。

關(guān)鍵詞：單片機；遠程電話控制系統(tǒng)；雙音解碼

Abstract
By using sound commands of sound recognition technology, this system realizes its control of household electrical appliances through telephone networks and so realizes the intelligently control of them in residence. The embedded and intelligent sound indication, its outstanding sound function of prompt and its code control system enable the operators to timely obtain the relative information of the controlled objects through indicated sounds. The system can use telephone to control many household electrical appliances in long distance through uttering sound commands and provides the code safeguard function. Only through inputting the correct password to control them, the users can control the condition of household electrical equipment, So the system security can be improved.

KEY WORDS: single-chip; telephone remote control system; DTMF
