The Design And Research Of The Appliance Network Control System Based On Embedded System

With the rapid development of network technology, digital technology and communications technology, people put forward a more and more high request for automation to home life. Informationization and with networked of household appliances are important content in the automation of family, which also to become the inevitable trend of the development directions of appliance automation.Information Appliances refers to the combination of micro-computer and communications technology into the traditional household appliances. It makes appliances become intelligent and have the abilities to obtain and process information at any moment. Consequently, it is greatly important to study and design the control system of network in household appliances.The thesis has introduced the concepts of digital family and proposed extensively the development of information appliances at home and abroad in modern society, an application of embedded Internet is also designed in this article. This thesis has described the whole scheme of control system then provides the software and hardware structure chart of the information appliances. Then describes the hardware and software design process of system. As for hardware design, the detailed construction and function description of every hardware component are given. As for the software design, the configuration and compilation of standard ARM-Linux are described in detail and other system software designs. This paper gives a completely new design concept, method and put forward the concept of home appliances order form. At the same time, the paper research a series of key technologies, including client, server and to explain the implementation etc.The paper probe into the operating system Linux and put up the development environment of operating system linux2.6.21, has laid a solid foundation for the work of transplantation for the future.The paper have discussed the terminal framework of information appliance, besides have chosen ARM-Linux operating system as transplanting to the target based on the analysis and the study about communications of network in the conditions of embedded operating system. Probe into thoroughly, reduce protocol of interrelated communications and has succeeded in transplanting it to the platform of hardware taking S3C2410 micro-processor as the core.Thesis also related to ARM-Linux core reduction, network Appliance's core structure and based on detailed analysis of S3C2410 processor and designed the application program in the conditions of embedded Linux operating system. According to the characteristics of home appliances, paper establishes a control order form. The method reflects the characteristics of home appliances with network.Confirmed the B/S mode based on the requirement analysis of system. Have transplanted embedded Web server boa, then carried on the development of the application program on the basis of here.The result of the test indicates, the system has the Characteristics of low-cost, simplicity, and high-adaptability in the applications, and has a good reference value to realize the family information system and control of the other appliances.
