Research And Implement Of Smart Home Networking System Based Linux

Home automation and home networking is the future of intelligence home. The digital home networking will provide users with a comfortable and convenient life. To the composing of home networking, the interconnecting technique and standard refer to the following aspect: all kind of digital device connected, the internet and high level application connected, the technique and standard of management and control, the standard of intelligent appliance.That, how to choose the right technology and method to design a system and suit the situation of our country , has become an important task for the real of smart home. Bluetooth technology, a new wireless technology in ISM band, can replace the cable and freely transmit data and voice in short distance. Because of widely supporting, open standard, and low power and high security, now the Bluetooth has been aeeepted by more and more people. The application to smart home is one of the most important applications of Bluetooth, and it drives Bluetooth's development.The work of this paper is for the research of the technique of intelligent networking home system and gives the center part of it .Specially, enhance and research the application of the technique of the Bluetooth.Firstly, analyze the origination, development and research status of the digital community and intelligent home. After analyzing and demonstrating the technique of intelligent home networking system, which is popular, the Bluetooth is chose as the main technique of this paper. And analyzing the protocol stack of the Bluetooth, giving the detail of the development scheme of the Bluetooth appliance and designing the Bluetooth communication software.In the networking home system, the main part is the home control center (home gateway), appliance, security device through the RSS-232 or Ethernet to connect to control center. The interconnect and outerconnect smart home is all through the control center. The LPC2200 develop system is chose as the center of smart home control centre. The embedded system is Linux.An applicable and extendable networking home protocol is the basement of the networking system. This paper references several network protocols and design the protocol of smart home network, fully considerate the application, system extendibility and performance. Finally, give a gateway based in Bluetooth and construct a smart home system.
