The Design And Implementation Of Smart Home Comprehensive Control System Based On ARM

With the progress of science and technology , all kinds of automatic and intelligent product emerge in endlessly .It greatly changed people's life style and thinking mode. In this context, the people on residential concept has changed a lot and put forward higher request on living environment. Smart Home concept emerged at the historic moment. Based on the existing Smart Home system as the research object, this paper analyses the current Smart Home solution characteristics and deficiency. Combining the current domestic Smart Home development circumstance, design a kind of traditional residence based Smart Home comprehensive control system . The system with the central controller as the core, adopted new ZigBee technology as control network means of communication, using modular design methods, in the peripheral modules coordinates, realized such as: remote control, temperature gathering, traditional household appliances control, lighting control and so on a series of function.This paper first analyzes several typical Smart Home solutions, in reference to and analysis on the basis of present project, the author puts forward his own overall scheme and detail designed the family internal subnet,then proposed his own improvement plan on the security of wireless sensor network technology of ZigBee. In the central controller design, it used samsung's 2440_ARM 9 microprocessor as hardware platform; using the embedded Linux operating system and BOA embedded Web server for software platform. Through the Common Gateway Interface (CGI) realized the functions of understanding the home situation and various equipment control through web browser. Peripheral modules part mainly realizes the infrared forwarding module, temperature acquisition module, lighting/power switch control module independent, meanwhile finishing the integrated work of network monitoring,GSM alarm module and such on.Each module through family subnet ,closely linked together to central controller,form a complete set of system.Finally,through central controller for each module remote practical testing,each module function is normal, Basically comply with expected results.
