Mobile Scouting-Controlling System's Design And Develop Of The Intelligent Home

In the process of popularizing the smart home in China, the reality and the step should be considered. The intelligent home should meet many kinds of need, such as the control to the device, the entertainment, the home security, the remote education and the remote medical treatment, considering the cost and the reality, the article focuses on the mobile controlling field about the intelligent home. And based on the hardware platform of the embedded system, the article develops the mobile scouting-controlling system with the technology of the mobile communication, the embedded system and the computer network. The feasible methods are found out to resolve the concerned issues, such as the user interface, the safety mechanism, the communication model, the conflict settling, the devices type, moreover the upgrading interface are remained .On the basis of the wireless PDA and PPSM, the wireless controlling device is developed. The work includes the control button's designing based on the GUI and the graphics cache and the windows' developing .Also the UART communication programmer and the data frame are defined to prevent the data loss, and the controlling interface are designed .Based on the OURS2410 and MIZI Linux, the home gateway is constructed, and the scouting-controlling module is developed to meet the user's need. With the serial communication function and the process API, programming the mobile controlling service agent and the terminal node(device) server, which can receive, send, encode, decode the signals and execute the programs. In order to cope with the problem about the message conflict and the realtime signal notice, many kinds of IPC methods ,such as pipe, signal and message queue are used. And the device variable is defined to simulate the real device, the device file datasheet is used to store , arrange and manage the device variable .On the basis of the home facility, conceiving the idea of the controlling subnet.The controlling subnet and its physical interface's design is introduced in detail,In order to save the cost, the article has designed the simulating terminal device intead of the actual device and tested the performance of the system.In the end, the article summarizes the work , analyze its significance and expects the future of the intelligent home.
