摘　要
 隨著社會的發(fā)展和科技的進(jìn)步，越來越多的家用電器進(jìn)入了人們的生活，這些家用電器給人們的生活帶來了很多的方便和享受，同時(shí)隨著電話在家庭的普及，電話機(jī)的功能將進(jìn)一步得到開發(fā)和利用。利用電話實(shí)現(xiàn)家用電器遙控是家電未來的發(fā)展方向之一。
 本文介紹了一種基于AT89C51單片機(jī)的家用電器電話遙控裝置，該裝置利用雙音多頻電話機(jī)，可以通過電話對家用電器及其工作狀況進(jìn)行控制。它是一種基于DTMF（雙音多頻）信號的遠(yuǎn)程智能控制器。它具有振鈴檢測和模擬摘機(jī)，DTMF信號解調(diào)和133秒無響應(yīng)自動掛機(jī)的功能。
 設(shè)計(jì)以AT89C51 單片機(jī)作為控制核心的電話遠(yuǎn)程控制器，重點(diǎn)介紹該控制器的各模塊組成、原理及具體實(shí)現(xiàn)的電路，該控制器采用現(xiàn)有的電話線路進(jìn)行通信，無需重新布線且通信距離不受限制，經(jīng)實(shí)際運(yùn)行表明，該控制器具有運(yùn)行可靠、成本低、操作方便，適用性強(qiáng)的特點(diǎn)、可以廣泛應(yīng)用于城市社區(qū)，具有較大的推廣價(jià)值。

Abstract
 With the development of scientific technology，an increasing number of home appliances have come into people's daily lives. These home appliances have brought in much convenience and enjoyment to people's life. The function of telephones will be further utilized and developed along with the popularization of telephones. Home appliances will probably be controlled by the telephone using the remote control technique in the future.
 This paper gave an introduction of such a device, a phone control of home applicances based on AT89C51 SCM. The device took advantage of the DTMF telephone, which was used to handle the operation of the home applicance. It was a kind of long-distance intelligent controller based on the DTMF signal with multiple functions, such as shake-bell examination，pick-up simulation，DTMF signal demodulation，hang-up after no-answer for 113 seconds，etc.
 A telephone remote controller based on AT89C51 single chip computer was designed in this paper，while the modules principles and circuit s in the controller was mainly introduced. It used the existing telephone line for communication without laying line again and without the limit of communication distance. In fact, the controller showed its great advantages in the practical application, such as a high reliability and applicability but a low cost and easy operation. Therefore, the device could be applied to communities in the city and its well worth doing so.
