| The soaring and booming development of network and communication technology into human being's life raises people's demands for automation and information of household appliances,which challenges improved flexibility of machine control and better convenience to obtain external information.The implementation of these requirements is firmly connected to the home network in which the home gateway,as the interface associating internal home network and the external network comes into the core of research.Adopting the relative research achievements home and abroad,following the "Well-being Society" residential building standards issued by the Construction Ministry of China,conforming to the Chinese household requests,a set of home Gateway is devised.Aimed to the construction of intelligent home network,Firstly,Based on S3C2410 development board on which it expanse bluetooth device and Man-machine interface device,We build the platform for system's hardware developing;Based on embedded Linux system on which it achieved reduction and transplant,We build the platform for system's software developing and achieved the bluetooth connection.Secondly,based on the Internet technology,an embedded Web server is completed in the gateway.As a result,the application program of server terminal is explored,which enables possibility of communication between the home gateway and external Internet network,and Web service in a family is accomplished. Therefore,it is possible for a user to log in the host web page of the home network through the Internet browser whenever he is,thus remote control on his electrical appliances is implemented.Lastly,Based on QT/Embedded,We designed a local services system to achieve electrical appliances' local control by bluetooth.This home gateway fulfils the connection and protocol switch between high-speed network and low-speed control and solved the most important and most difficult problem in this area. The application of embedded Web technology,bluetooth technology and the software design in QT/Embedded in this home gateway features this paper.It is proven by the system software that exploiting the current web resource,this home gateway system claims flexibility,stability and convenience on household electronic appliances' control,shared information.The expected requirements have been fulfilled. |
