| In this paper, intelligent appliances and wireless network control system design andinstallation of the family unit, every home had a home gateway, a number of wireless sensornodes modules, to achieve control of home appliances home gateways and ZigBee node networksystem design . In the home gateway and each child node are connected with a wirelesstransceiver module, through which a wireless network transceiver modules, data at the gatewaybetween the transmission and sub-nodes.Based on field study and experiments, the paper focuseson the following areas.Firstly, the overall network platform is established, based on wireless network techonology.It usew microprocessor S3C4510B for core, and expands it and MSP430 controller; secondly,CC2420 transceiver is used to analyze device signal; thirdly, correspondence platform forMSP430 and CC2420 are established which facilitate the establishment of wireless networkplatform of electric device. In the development of the technology, we get acquainted withdevices S3C4510, MSP430 and CC2420 and the technology of establishing wireless network.The paper puts forward a blueprint for wireless control, based on ZigBee agreement anddeveloped embedded wireless HomeGateway which uses the 32-bit embedded microprocessorARM S3C4510B for core, and established data conveying platform through expanding MSP430controller and CC2420 transceiver. The newly-emerged ZigBee is a wireless communicationtechnology which shows a good performance in low power consumption and stability and is wellqualified to undertake some small tasks which has small data flux and low demanding QoS.Therefore, device contolled in home is the one ZigBee suits. In the real application, sensornetwork can form a wireless local netowork through major coordinating device, nodes in thecircle and RFD terminal node. The nodes in the circle extend communication distance. Therefore,control over home electric device and relatively long-distant control are possible. |
