Abstract
In order to realize the interconnection of home network,Ethernet and GSM,a design scheme of a wireless embedded smart home gateway is proposed.S3C2440 is adopted as the central processor in the gateway hardware.The ZigBee protocol is taken to build the internal home network,which connects the external network through Ethernet and GSM modules.The software platform uses Linux operating system to design the gateway application program bythe aid of the cross compiler.According to the test requirements,application function demand analysis is discussed and graphical user interface is designed to accomplish the function tests,in which Qtopia Core is selected as the embedded GUI.The embedded home gateway system based on ARM9 and Linux has well-defined architechure,good extensibility and high-speed data processing.The system is easy to use,and can test several functions of the home network.
