Research Of Access Technology Based On Zigbee And Internet

A kind of technology progress can often generation and development other technical,in recent years, along with the development of information technology、 networktechnology and other various kinds of short distance wireless technology，and in the face ofsome problems in need of communication with people in the real life，eager to have astrong application ability, low energy consumption and convenient network of wirelesscommunication technology meet the application requirements,Zigbee technology isproduced under such a background，Nowdays Zigbee and sensor technology combine toform of wireless sensor network technology and application widely.According to somemedia, WSN is thought to one of the most important wireless network communicationtechnology influence of human’s life in the future, and it has a vast application prospect inthe national defense, environmental monitoring and prediction, all kinds of intelligentproducts and industrial production and manufacturing other fieldsThis paper puts forward“research of access technology based on Zigbee and Internet", it combines Zigbee wireless sensor network technology, embedded technology andwireless Internet access technology, Zigbee wireless sensor network is combined with theInternet which is are familiar with the Internet nowdays, makes the wireless sensornetwork (WSN) can transmission of data collected on a computer or other Internetintelligent terminal real-time accurate, complete Zigbee wireless access to the Internet ortransmission of data collected on a computer or the reverse process. And according to thepresent problems on this topic research, this paper by identity authentication mechanismenhance system security coefficient, through the identity authentication mechanism toimprove the legitimacy of the user login, how to ensure data from illegal to steal, illegalchange, thereby implementation wireless sensor networks and the Internet is safe andeffective fusion.In this paper, we select cc2530wireless rf chip of TI company as zigbee wirelessnetwork core components, and arm9-based architecture s3c2440processor as the core ofthe two network transformation network transformation center,PC as Internet receiving andcontrol equipment, has developed a complete set of embedded network transformation tothe server, and completed hardware platform of the system, by Zigbee terminal nodes onthe sensors to collect all kinds of measured signal, using high-performance cc2530wirelesstransceiver chip acquisition signal gathered in the storage unit to the coordinator, the datacollected by Zigbee protocol stack is packaged as a Zigbee format and converted into Ippackets in the processor, set up one-one-mapping wiith Ip address and Zigbee network short address, to determine send purpose, whereas in embedded systems and the Internetterminal socket communication process is established. And by embedded USB wirelessnetwork card to Ethernet encapsulation with the data which data processing into TCP/IPprotocol stack, and then through the wireless network card sent to the terminal on theInternet, or Zigbee network node receives the control commands and to respond, And usethe Linux-PAM module completed the user login authentication, make sure that user’slegal login, to ensure the safe use of Zigbee network data, so as to realize seamlessintegration of Zigbee wireless sensor network and the Internet.The last test system, namely detection on the Internet to receive Zigbee data andZigbee node receives the control commands...
