The Research And Realization Of Embedded Web Server Based On ARM Platform

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 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 S3C2410 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, under the 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.Secondly, based on S3C2410 microprocessor and Linux operation system, hardware and software platform has been built for embedded developed system, which is used to design embedded Web server.Thirdly, 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, and then completes the design of hardware circuit Fourthly, 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, the common protocols of TCP/IP and HTTP are been analyzed, which it is basic to research the embedded Web server principle and to analyze the structure of Boa server program. In order to minitor remote central air-conditoning, an embedded Web Server with good dynamic Web page function is designed and realized in the endThe result of the experiment shows that the remote central air-conditoning system based on Web works smoothly, and has user-friendly interface with good dynamic Web page function.So it can monitor the central air-conditoning through the parameter of temperature, pressure and error alarm.
