The Study And Implementation Of Home Web Gateway With IACP

People were calling for more demands for automation degree of daily life with the emergence of information appliances and development of cyber technology. The home web was made up with home appliances and accessed through Internet remote service. It has turned to an important intelligence tool. Therefore, building up the web of HIAs (home information appliances) based on IP and syncretizing with computer cyber by IP technology was the tendency for the future information appliances. In terms of universality and convenience, it would be the optimal option for HIA to provide Internet remote access service based on Web.On controlling the appliances on Web pages, a new method of using Web gateway via Internet to control and manage HIAs in the paper was brought forward. The web gateway managed every HIA with the customized IACP (Intelligent Appliances Control Protocol) inside the HIA net, and distributed Web services to Internet. This method owned the primary advantages of the dynamic detecting, automatic configuring, light-weighted design and applying the general TCP/IP protocol.The paper firstly gave the present survey of HIAs, then further discussed the traditional two ways of remote access HIAs. After analyzing the status of research on this issue, a design goal and a general scheme for Web gateway with customized IACP was given. A detailed explanation about the design and definition of IACP was made to manage the other electronic devices in the home web, for it was key of this solution. Taking IACP-Web server implemented onμClinux for examples, the paper explained the key technology and fulfilling means of IACP and Web services, and particularly analyzed the interaction process of IACP and Web services. Then IACP client terminal was done on the home appliance onμC/OS-II andμClinux systems. Finally the prototype was used to verify the validity and reliability of IACP.The home Web gateway based on customized IACP had great expansibility, flexible configuration. It had great value of references to fulfill embedded Internet technology on reducing cost and using limited resources.
