| The development of network technology and digital information has provided a strong technical support for the realization of intelligent family life; the development of sensor technology provides a technical foundation for the exchange of home equipment and network; and the development of computer and embedded technology also provides a good technical support for the various equipment detection, control, and management. The emergence of the new technology has enabled new demands of people's life and work environment. A Home Gateway which can bring devices into home network is the most important problem to realize the intelligent service and management.As traditional Home Gateway can not connect various sensor devices located in different places conveniently in our home, therefore, this paper proposes a design concept: relay controller, which is separated from the complex Home Gateway and can join all the sensor devices located in different places. Its basic function includes: bring a new device into the whole system quickly, it can realize plug and play; It also has intelligent analyze function such as according to variational data, it can simulate human to analyze and operate the device; It can communicate with Home Gateway, provide the function of remote control, query, management and so on.This control system is based on S3C2410 processor and real time embedded Linux operating system which can improve the reliability greatly. This paper introduces the hardware and software design in details, and also introduces how to realize the software; In addition, this paper has also proposed a communication way based on independent communication protocol which can improve the system real time function and reliability.This paper is based on the project"design of relay system for sensor and switch"which is cooperated with Japanese NTT Corporation. |
