According to the existing development mode of intelligent Home Furnishing system and the analysis of functional requirements, the paper puts forward the general framework of intelligent Home Furnishing system, and designed the communication scheme of the system, and gives the system each function module realization. This paper mainly completes the design of networking, each function module of embedded intelligent family gateway server in the system building and CGI intelligent interactive program and CGI interactive program. Experiments show that each function module of the system meet to design requirements, the overall system can satisfy the actual demand Home Furnishing user, validated the feasibility of the B/S architecture in intelligent Home Furnishing system.展开更多
