 摘要
 隨著社會(huì)的發(fā)展和科技的進(jìn)步，越來(lái)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(lái)了很多的方便和享受，同時(shí)隨著電話(huà)在家庭的普及，電話(huà)機(jī)的功能將進(jìn)一步得到開(kāi)發(fā)和利用。利用電話(huà)實(shí)現(xiàn)家用電器遙控是家電未來(lái)的發(fā)展方向之一。
 本次畢業(yè)設(shè)計(jì)的題目是用AT89C51實(shí)現(xiàn)電話(huà)遠(yuǎn)程控制家用電器，該系統(tǒng)主要是由AT89C51單片機(jī)、DTMF解碼芯片MT8870、語(yǔ)音芯片ISD2560和存儲(chǔ)芯片24C02組成。可以用電話(huà)機(jī)或手機(jī)在任何地方、任何時(shí)刻通過(guò)此系統(tǒng)來(lái)遠(yuǎn)程控制家里的電器。該系統(tǒng)可以直接開(kāi)關(guān)電器、延時(shí)開(kāi)關(guān)電器、監(jiān)聽(tīng)家中聲音、密碼修改和存儲(chǔ)及其狀態(tài)查詢(xún)，并且有自動(dòng)語(yǔ)音提示功能。
 系統(tǒng)具有運(yùn)行可靠、成本低、操作方便、適用性強(qiáng)等特點(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.   
 The thesis of graduation designer is a remote-control system of home applicances, it is based on AT89C51 MCU with a phone.This system is mainly consisted of the AT89C51, DTMF decoder chip MT8870, Voice chip ISD2560 and memory chip 24C02. The telephone or the cell phone can be used at any place, any time through a intelligent telephone remote control system to control home appliances. This system has a function to turn on the home applicances directly,or turn on the home applicances in a defintly time. Wiretapping , changing and storing passwords and inquirying the state of home applicances. 
 In fact, the system showed its great advantages in the practical application, such as a high reliability and applicability but a low cost and easy operations. Therefore, the device could be applied to communite in the city and its well worth doing so.
