| With the quick development of computer science, network technology and the economy, people’s living standards have improved a lot. Information society is changing people’s lifestyle and work habits, and people are eager for the intelligent digital home of higher requirements. Because there are so many types family equipment and network in a different way, It is realistic significant to realize unified management between intelligent devices with different protocols.So, the paper designs the heterogeneous intelligent digital home based on ZigBee and IGRS protocols. Combined ZigBee technology.IGRS technology with embedded technology, the TI OMAP EVM is chosen as the hardware platform for the central gateway. Through gateway, within the network devices can interact information freely, and also remote control. The main content of research as followed:Firstly, we learn about the ZigBee wireless communication protocol. Form digital home control network by the tree topology construction, make communication protocol between gateway and ZigBee wireless, and realize data acquisition and control of the equipment with the platform by serial, also shows the information on the display.Secondly, by the related technology of embedded development, we especially research on the OMAP3503EVM and its peripheral equipments and the application of Linux operating system. Building gateway platform and realize the information interaction between gateway platform and ZigBee network and PCThirdly, using the technology of the application framework, information interaction mode of IGRS protocol, we make a feasible scheme for Heterogeneous Network-related, which can be a theoretical basis to realize the information transmission between the heterogeneous devices.Lastly, we research the operating mechanism of the WEB server and CGI, Combined with embedded system to transplant the BOA server, design the user interface and realize the remote access about home network on the OMAP3503platform. |
