摘 要
本文設(shè)計(jì)的是一種基于AT89C51單片機(jī)的遠(yuǎn)程電話控制系統(tǒng)。控制系統(tǒng)是以單片機(jī)AT89C51為核心、基于電話網(wǎng)絡(luò)開發(fā)的家用智能電話控制電器。利用電話網(wǎng)傳輸數(shù)字和語音信息，遠(yuǎn)程控制部分接收電話網(wǎng)發(fā)送來的DTMF信號(hào)，對(duì)其進(jìn)行解碼，解碼后由中央處理器AT89C51根據(jù)解碼信息控制家用電器；本系統(tǒng)設(shè)計(jì)實(shí)用，功能靈活多樣，可靠性高，操作方便，可以廣泛地應(yīng)用于家庭或者其它場(chǎng)所的智能控制。電話遠(yuǎn)程控制不需進(jìn)行專門的布線,不占用無線電頻率資源, 還可避免電磁污染。通過基于語音處理技術(shù)及DTMF解碼技術(shù)的遠(yuǎn)程控制系統(tǒng), 運(yùn)用語音識(shí)別技術(shù), 以及語音命令通過電話網(wǎng)絡(luò)來控制家用電器的開與關(guān), 從而實(shí)現(xiàn)智能住宅中電器遠(yuǎn)程可控化。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(shí)了解受控對(duì)象的有關(guān)信息。系統(tǒng)可實(shí)現(xiàn)通過發(fā)出語音命令用電話遠(yuǎn)程控制多個(gè)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。

Abstract
The article designed the remote telephone control system which based on microcontroller AT89C51. Basing on the telephone net, the system which uses the core controller Single-chip microcomputer AT89C51 realizes long-distance control household appliances . The telephone control system, which uses the telephone net convert and voice information receives DTMF code from the telephone net, and interpret the code, the core controller AT89C51 controls the state of household appliances responded to the interpretation. This system is practical, and the function is flexible, and the operation is convenient with high reliability, which can be used extensive in various kinds of control equipment to home and others field. Long distance control of telephone does not require special wires distribution and does not take up wireless frequency resources. Electro magnetic pollution can thus be avoided. The designing of a system of long－distance control based on sound processing technology and DTMF decoding technology is presented in this paper. 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.
