The Research And Design On Intelligent Home Network System Based On Embedded Technique

With the development of the network and information technology, smart home are becoming realization. Home network is an important part of home information basic installation. By home network, some instruments, such as communication equipment, electrical appliances, home alarm equipment can be combined to constitute a system of smart home for monitoring, controlling and managing at different areas. Meantime, home network can keep home instruments coordinating with home environment. The construction of the intelligent community will solve the bottle-neck problem of the last stage, spread the information high way to the community and home, and bring the safe, convenient, economical, comfortable life to the residents.The paper aims at constructing intelligent home network and smart home. Firstly, study embedded operating system uClinux and the ARM processor. Secondly,analyze network environment of the intelligent community, provide network constructive solution,study on the architectures of home network and the function architectures of intelligent home.Again the main content is the research of smart home gateway based on the 32-bit ARM and embedded real-time operating system. Considering the stability and expansibility, the system adopts the embedded operating system uClinux and the ARM processor of S3C44B0X , an advanced 32-bit embedded RISC microprocessor. It describes the hardware design of the gateway, and then discusses the process of the transplant of operating system. It expatiates the realization of embedded TCP/IP protocol and the communication between the gateway with Ethernet.Finally, this paper introduces the system of meter reading at home based on the home gateway. The system of meter reading at home provides the management of daily water, electricity, coal gas sale and monitors three lists.
