Design And Implementation Of Wireless Smart Home Gateway Base On ARM9

With the network， the intelligent Era， High speed network is coveraged，And the Internetin embedded intelligent control terminal development provides important technical supportnetwork. And intelligent household equipment networking is imperative. Follow this importantdevelopment trend people put more scientific research in intelligent home network， intelligentand more convenient on the benefit of users.At first the concept of smart home is introduced in this paper. After analyzing thedevelopment tendency of the smart home industry both at home and abroad, this article gives thedesign of a new type of smart home gateway. The main work is given as follows.First, the solution of smart home is analyzed, the types of hardware and software are selected,and the whole design scheme, based on the WMRNET network, is given. Second, on the basis ofthe ARM9core processor, this paper designs the peripheral circuits such as the USBcommunication circuit, RS232switching circuit, control circuit of peripheral equipment andinterface circuit of the touch screen, and the wireless concentrator module is explained. Third, thecore of linux is trimed and transplanted. Then, the drive programs of the outer equipments aredesigned and loaded. The embedded Webserver is fabricated, based on which and the CGItechnology, the gateway application program and operational interface are designed. After that, thecommunication protocol of the gateway system and WMRNET network is presented. On this basis,the data on the operational interface and video can be displayed by applying the MiniGUItechnology. At last, the gateway system is tested in aspects such as the control of electricalequipment, Webserver, the control of local interface, the display function, etc. After the overall test,prove gateway system meet the design requirements and has certain application value.
