Design Of Home Network Protocol For Automatic Generation Of Interface

The automation of household facilities has been raised into a new age by home networks technology. Household facilities have become networking, interactive, resource sharing and remote controlled. These goals have been reached by those home-networking-protocols nowadays. But those home networking protocol require a high processing capacity. Up to now, there are few solutions for automatioc generation of interface generation. The Home Network Protocol for Automatic Generation of Interface in the paper bases on TCP/IP and byte-coding, which reduces request of processing capacity. Key-Infromation of Interface Generation is also defined in this protocol.The main work is as follows:1. The controller of household facilities and the control interface of soft-devices on PC are analyzed. The following points are abstracted: partition according service relation; figure and orientation of buttons. These have been integrated to the protocol and used in the automatic generation of interface.2. The Home Network Protocol for Automatic Generation of Interface has been researched and designed. The protocol supports plug and play, and automatic update of service. In the protocol, the interaction and encode of message has been defined. It contains four parts: discover of service, description of service, control of service and event notify. It is successful in automatic discover and update, and distributed control of service. The protocol can be implemented on any operating system with any programming language. Moreover, it can be implemented on a low hardware without operating system.3. A home gateway system based on B/S structure has been designed. The home gateway system is based on the protocol, and uses http server and CGI technology. It obtains service status and auxiliary message for presentation from the service description and event notify messages. With these messages, an html is generated according the template, which can present the service status and control interface. User visits the home gateway site in his or her web browser. Now he or she can control home facilities remotely.The innovation is as follows:1. The"Key-Information of Interface Generation"is new. The partition and splicing of service region, and the encoding and locating of buttons are new. These make byte-encoding messages take along with the interface information.2. The home network protocol base on byte-encoding over TCP/IP is new. The protocol is automatically generated for the interface, plug and play and service dynamic update.
