ZigBee Technology Applied In Intellectualized Home

With the high development of information technology and network technol-ogy,and people change their notion in their dwell,what people want is to simplify and intelligentize the details of live, to embed kinds of intelligentized programs in home application and enjoy the simple life of"one key's OK"type.The concepts, such as intelligent home, networked house,home network, digital family of intellectual home, digital home, etc. are proposed extensively at home and abroad, more and more new technologies are getting application in family intelligent system one after another.The research of intelligent family of low power consumption, low cost,easy group network, is a multidisciplinary to cross subjects for research which are relevant to automation, computer, communication, etc. ZigBee is a new global standard for wireless connectivity, having wide foreground of products within home control, building automation and industrial control and monitoring. It is now widely recognized that standards such as Bluetooth and WLAN are not suited for low power applications, which is due to these standards' high node costs as well as complex protocols and high power.Based on the ZigBee wireless technology will be used in the intelligent ho-me,and even through the internet and mobile phones remote monitoring equipm-ent to achieve the management of the intelligent home concept, building a intelli-gent home system that intra-family wireless network and external WAN commu- nicate through home gateway.Zigbee studied various communication protocols level of the specific functi-on and role.Used Jennic corporation's JN5139R1-M0 module, it conforms to the ZigBee standard. Taking this module as the core design node hardware circuit, b-ased on opened the source code to complete the coordinator and the terminal no- de software related application design to set up wireless networks of intelligent home.Home gateway is composed of the internal network coordinator and the embedded Web server two parts. Both carry out their duties, the former leading sensor network, the latter communicating with the outside network.In order to achieve remote monitoring function, embedded Linux as a platform to build a Web server, and a database Sqlite transplantation. Users through the home gateway to the purpose of the intelligent home monitoring.The experimental results show that users through the family gateway can be real-time monitoring and management of intelligent home equipment, ZigBee wi-reless technology suited to form intelligent home systems, system installation co- nvenience, scalability, and a good practical value.
