Based On The Design And Realization Of Embedded Smart Home Gateway System

In the family information system network technology research and product development, family and Internet connectivity needs of a family network, the central controller, or so-called "home gateway." Home gateway externally link with Internet, internal LAN join household appliances and other power consuming facility into an organic whole inside house, have offered network platform and open automatic system directed against the consumption electronic product, can realize the intellectual house , various kinds of functions and services of the electrical home appliances network on this basis.The main results are as follow:1.At first the thesis has introduced embedded system and the definition of the embedded home gateway, development overview, etc. Then provided the hardware structure of the home gateway.2.Linux operating system and uClinux kernel operating mechanism are analyzed in this thesis. After analyzing Linux systematic operating principle, we have discussed the Linux equipment driver and developing several instances concretely. At the same time, uClinux operating system is transplanted on the goal board.3.After analyzing common protocol TCP/IP and HTTP protocols, cooperating with the need of researching, we apply them to embedded Web Server system. Then the embedded Web principle is researching, and the procedure of developing on CGI technology and socket technology are summarized. Confirmed the B/S mode based on the requirement analysis of system.
