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.
