The Study And Implementation Of Smart Home Control System Based On Wireless Technology

The smart home is the combination of computer technology, communication technology and automatic control technology.It includes centralized controling of various types of household appliances, Monitoring the running security equipment, automatically adjusting environmental conditions and other aspects. The goal is to provide a more comfortable and safer home environment.The concept of domestic intelligence system originated in the late1970s, the United States. followed by the rapid development in Europe, Japan and other countries. It appears late in our country, around the late1990s. In recent years, it developes very fast, some areas already have some intelligent residence community.This paper introduces the current smart home system status, and analyzes the deficiencies of the existing smart home system, compares the advantages and disadvantages of the achieveing mode, proposed theory and methods of a smart home control system based on wireless data transmission network.Aiming at the features and functions to be achieved of the smart home, the system adopts the architecture model of combining centralized management and hierarchical control, uses80C51series microcontroller as controling node,315MHz wireless technology as data transfering channels, combines with infrared remote control technology, the XML database technology. In the project, the intelligent gateway module, device control module, user operation module are designed.And the goals of anipulating household appliances easily, turning off the lamps and all kinds of power are implented. The system basically realizes features of the smart home, and has the advantages of low-cost, convenient, easy-to-use extension.
