The Design And Implementation Of Smart Home System Based On ARM And Linux

As the Internet technology, automatic control technology and the rapiddevelopment of information technology, and constantly to life, the prototype of thesmart home gradually emerge.Intelligent home control system widely used in moderntechnology to create a safe, comfortable, high efficiency, energy saving andenvironmental protection household environment.Intelligent home control systembased on residential platform, combining with computer technology, automationtechnology, embedded technology, wireless communication technology into anorganic whole, implementation within the family or the remote control devices in thehome, such as: security entrance guard system, household gas detection system,temperature control system, and audio video systems, etc.Intelligence lives in thepresent stage, our country is in a high-speed development period, the control systemof smart home is of great significance to the study and research.Based on theembedded technology, network technology, ZigBee wireless communicationtechnology to achieve the combination of smart home system, and research willfocus on the core of the smart home system, intelligent home gateway.Among them,the smart home gateway based on ARM processor is analyzed and the design ofhardware and software.Gateway is different from the traditional smart home system,this paper implemented in intelligent home gateway is set up a web server, the usercan be in any one connected to the terminal through the browser login smart homegateway, view your household equipment status and control equipment, to someextent, improve the convenience of user access.After the user login the smart homesystem can view the state of household intelligent devices, and to control themovement of household intelligent devices.Smart home gateway after receive theuser’s command, analysis processing and then sends a command to the smart homeLAN ZigBee coordinator implementation view and control of theequipment.Through timing data upload display implementation of householdequipment state monitoring, also joined the scene mode, so as to realize the controlof the furniture equipment more humanized.First, the concept of smart home systemmade simple introduction, and the present research situation and developmentprospects of smart home are expounded.Then make this system needs analysis, the system’s overall function orientation and determine the overall design scheme of thegateway.The focus of the paper is based on the ARM platform software development,mainly includes three aspects:(1) the content of the transplanted BootLoader andLinux system into mini2440development board and making root file system, so as toprepare software platform.(2) set up the network server and making web pages,writing CGI application, to realize the remote control.(3) the gateway and ZigBeecoordinator of communication protocol, realize the communication with intelligenthousehold device node.After experiment and debugging, this thesis implemented thesystem of basic can achieve through web remote viewing equipment running status,and to control them.
