摘  　要

 隨著單片機(jī)技術(shù)和信息的高速發(fā)展，人們對家居的要求早已不只是物理空間，更為關(guān)注的是一個(gè)安全、方便、舒適的居家環(huán)境。因此，智能家居越來越受到人們的關(guān)注。
 本文設(shè)計(jì)的家用智能控制裝置，以單片機(jī)89C51為主體設(shè)計(jì)而成，集紅外探測報(bào)警裝置，燃?xì)庑孤秷?bào)警裝置，電話遠(yuǎn)程家電控制裝置于一體，可以實(shí)現(xiàn)安防報(bào)警和遠(yuǎn)程遙控家電的功能，是一種結(jié)構(gòu)簡單、使用方便、成本低廉的家庭用智能控制裝置。
 安防電路分為射頻發(fā)射電路和射頻接收電路，使用VD5026、VD5027對報(bào)警信號進(jìn)行編碼、譯碼，DBY-R14A發(fā)射、接收模塊對報(bào)警信號進(jìn)行傳遞；該部分充分利用了紅外線的隱蔽性和傳遞性，從而達(dá)到了安全防護(hù)之目的。電話遠(yuǎn)程遙控電路利用現(xiàn)有公用電話網(wǎng)進(jìn)行遠(yuǎn)程控制，使用MT8870對DTMF信號進(jìn)行解碼，通過單片機(jī)控制家用電器電源的開關(guān)，從而可實(shí)現(xiàn)用固定電話或移動(dòng)電話對各種家用電器設(shè)備的遠(yuǎn)程控制。

 Intelligent Home Control System

Abstract
 SCM technology and information with the rapid development of domestic requirements of people had not only physical space, more attention is a safe, convenient, comfortable home environment. Therefore, the intelligent home more and more attention.
 This design of intelligent home control devices to microcontroller 89C51 formed as the main design, set infrared detection and alarm devices, gas leak alarm, telephone remote appliance control devices in one, you can achieve security alarm and remote control home appliances, which is an simple structure, easy to use, low-cost home with intelligent control devices.
 Security circuits into radio frequency transmitter and RF receiver circuit, use VD5026, VD5027 of the alarm signal encode, decode; use DBY-R14A transmitter and receiver module of the alarm signal transmission; the full use of the infrared part of the hidden nature and impart, thus reaching security purposes. Telephone remote control circuits make use of existing public telephone network for remote control signals .Use the MT8870 of the DTMF decoder on, SCM control home appliances through the power switch, which can be realized with a fixed telephone or mobile phone equipment of various home appliances remote control.
