The Research And Implementation Of The Intelligent Network System For Building

The intelligent network system for building is an inevitable course with the development of information technology. According to the request of daily life for people, the thesis analyzes the function architecture for the intelligent network system for building, designs a home control center based on the technology of embedded web, defines the integrated communication criterion for the information appliance, develops the communication between the sanyo ECJ-218M electronic rice cooker and the control center, and achieves the remote control function to the appliance through the intelligent network system.According to the actual demand for the application, the intelligent network system is divided into four different functional parts, which are the environment maintenance subsystem, the security management subsystem, the information appliance subsystem and the automatic reading meter subsystem. The control center is carried out based on the ARM CPU, and takes on the home gateway function. The thesis achieves the configuration and installation of the uClinux, and based on which, develops the CGI and communication programs. The CGI programs response to the client request, and invoked by the web server Boa which is appropriative for the embedded OS. The criterion on the communication of the IA includes an up layer of application service and a low layer of communication control. The application service layer achieves the function of device identification, parameters update, and the remote control to the devices. The communication control layer takes the responsibility of the address management, the priority management and the transfer check work. And the criterion is applied on the commumcation between the sanyo ECJ-218M electronic rice cooker and the control center. The thesis takes the sanyo ECJ-218M electronic rice cooker as application object, implements the serial communication interface connected to the control center by using the I/O ports and timer interrupt of the MCU of the cooker controller.Based on the practical demand, the thesis studies on the function architecture for the intelligent network system for building. The thesis takes the sanyo 218MS electronic rice cooker as the object, carries out the network function for the information appliance, achieves the remote control, error alarm and other functions, which is valuable to the development of both information appliance and building network.
