The Research Of Embedded System In Home Gateway

The intelligence housing is following the computer, the correspondence, the network and the control technology development appears, the home gateway takes the intelligent housing the core facility, constitution and so on sensor which, PC and peripheral device by the information electrical appliances, the function varies home interior networks and the plot local area network relates, then the turning on internet, realizes functions and so on information sharing, remote control, centralized management. Along with the new technology's appearance, the home gateway's design also pours into the new vigor, this article introduced is one kind fuses the blue tooth technology embedded home gateway.The bluetooth technology is one kind uses in each kind fixing with between the motion digitized hardware equipment's low cost, the short distance wireless communication link technology, and may substitute for the troublesome electric cable in the home situation application. The main gateway is which the home principal network and the home public network or the community network outside connection, the home gateway is the true sense, but the sub-gateway is takes one"the equipment"to turn on the home principal network, it is the home control subnet to the home principal network connection. This article home subnet gateway blue tooth module uses sixth generation of chip BlueCore6 which CSR Corporation researched and developed recently, this chip uses the AuriStream technology, it is a blue tooth processing speech transmission way quantum leap, has provided the higher pronunciation quality, and the power loss reduced 40%, selects the PSTN turning on method in the control aspect to be most ideal.
