Design And Realization Of Intelligent Home Remote Control System Gateway Based On Double-network

With the development of technology and advancement of people's living quality, people turn to pay more attention on life's security, comfort, convenience etc. Smart home system is to connect the facilities and devices(such as lighting system, safeguard system and electrical equipments etc)using computer, embedded system, network technology by home network, which provides people more comfortable and convenient life. Smart home becomes a new development trend of housing development, and the Smart home market of China intensifies gradually day by day.By means of the analysis of Smart home remote control technology, with the deficiency of the Smart home remote control technology. A Smart home remote control system scheme based on dual-network has been presented and a Smart home remote control system gateway has been designed. The main works are as follows:According to the functions of Smart home gateway, the gateway global framework, protocol conversion model , hardware and software scheme have established in this paper. The core circuit of Smart home gateway has been designed in detail, including main LPC2294 controller chip circuit, memory system circuit, power and reset circuit, LCD interface circuit, keyboard circuit, PSTN interface circuit, Ethernet interface circuit, CAN interface circuit and other peripheral interfaces. In addition,μC/OS-Ⅱ, LwIP TCP/IP protocol stacks were trimmed and transplanted onto the LPC2294.μC/OS-Ⅱtasks, CAN-TCP/IP protocol conversion and CAN/PSTN protocol conversion were also developed. At last, using the queuing theory to obtain a performance analysis, The report proves that the Smart home gateway achieves an efficient and reliably interconnection among CAN and Internet and PSTN.
