摘要
为了实现家庭内部网路与Internet以及GSM网的互联,提出了一种嵌入式无线智能家居网关系统的设计方案。该网关系统的硬件平台以ARM920T核处理器S3C2440为主处理器,采用ZigBee协议建家庭内部网络,而且通过以太网模块和GSM模块接入外部网络。软件平台采用Linux操作系统,通过交叉编译设计网关的应用程序。最后,以Qtopia Core为嵌入式GUI,进行家庭网关监测应用软件的功能需求分析,设计图形用户界面,实现家庭内部信息的查询。基于ARM9和Linux的嵌入式网关系统,可扩展性强,数据处理速度快,使用简单,能够对家庭网络内部多项环境信息进行监测。
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.
