The Research And Application Of Embedded Web Server Based On Arm

Along with the development of the informationization, the intellectualization and the Network, the embedded system technology has obtained the broad development space. In another hand, with the fast development of information technology, the Ethernet communication technology has begun to be applied in industrial control and embedded system design, thus industrial Ethernet has gradually taken shape. The key technology of embedded industrial Ethernet is how to implement TCP/IP protocol and how to realize the embedded web server during node control module at the field level. This paper, upon conducting a detailed research and summary of the software and hardware of ARM (LPC2210) embedded system and TCP/IP protocol, has succeeded in designing a Ethernet-based remote collect system of the parameter of alternating current.This paper firstly reviews developments made in embedded system, and analyzes the technology of embedded web server used in embedded system. In order to meet the needs of Ethernet-based remote collect system of the parameter of alternating current, A detailed technical realization for embedded web server in the hardware and software platform is introduced.The paper first introducts the overall structure of the system and analyzes the function demands, then mainly studies the hardware circuit design and the software design of the module. The system chooses the plan"ARM+μC/OS-II"which used microprocessor LPC2210 as the core in hardware, andμC/OS-II as the operating system in software. The whole control system adopts the B/S architecture. By probing into TCP/IP, TCP/IP is reduced, amended and realized layeredly inμC/OS-II according to the need of the system. In order to meet the requirements of industrial control, a simple file system for the management of the paper's of website and support for dynamic Web pagesis used in this embedded web server.Finally, the paper gives an example used embedded web server—a Ethernet-based remote collect system of the parameter of alternating current. Then Analysis the prospect of this issue.
