Research On Embedded Web Server Construction And Application

With the development of Internet and the coming of the post-PC era, the embedded systems is becoming the center of interest in the current IT industry and exhibiting broad potential market.In the meantime, the access of embedded systems into the Internet has become an important direction of the present Internet development.The purpose of this design is to achieve the bank payment system of data collection and remote monitoring.The design of embedded system includes design of hardware and software.After discussed the development of the network monitor system,the thesis regarding ARM9 processor of AT91RM9200 as the platform, based on embedded Linux operation system,combining the relevant embedded Web technology,has carried on research on embedded web server,the main contents are as follows.Firstly, underthe background of the study on embedded system, combining with the theory of Inernet, the thesis presents a technology of embedded Web based on ARM platform after analyzing the process and prospect of network supervisory control system.With the practice based on AT91RM9200 microprocessor and Linux operation system, hardware and software platform has been built for embedded developed system, which is used to design embedded Web server.The thesis designs hardware circuit of the embedded system which includes the module circuit of Power, Time, JTAG, Serial Interface, and memorizer, and so on.In order to make embedded system work smoothly, it also needs to design software platform, such as bootloader, kernel and file system.The paper places emphasis on the development of device driver, espically net driver, and discuss how to compile it into the Linux kernel, and then the image file is downloaded into the target machine from host machine through JTAG and serial interfacer, debugged and running.Finally, which it is basic to research the embedded Web server principle and to analyze the structure of Appweb server program, the common protocols of TCP/IP and HTTP are been analyzed, and complete the transplant and the basic structure in the embedded Web server.This system provides a general embedded linux Platform, also realizes a web server with the ability of dynamic Page. it only need adding some function when developing new application system, and realize the purpose to long-distance monitor and control.
