The Design Of The Computer Room Monitoring System Based On Embedded Web Server

With the development and popularization of the national information industry, more and more scientific research institutions, schools, enterprises have computer rooms for scientific computing and digital management. If the computer room is managed by traditional hunman resource management model, it will not only waste human resources, but also can not control environment and equipment accurately and efficiently. So development of a high reliability monitoring and controlling system is very important.Based on the study of the national monitoring system and developing trends, for grid computing platform of Education Key Laboratory, a monitoring system was designed. This system can monitor real-time various environmental parameters of computer room, and can alarm by various means in the event of unusual circumstances and can mangage the emergence itself. It can protect instruments and equipments of the computer room in time. By analyzing the application requirements and the existing technologies, TCP/IP technology and Embedded Web technology are used in the system.This article describes the various hardware modules of the system, including control module which has MC9S12NE64 as a core, temperature measurement module based on digital temperature sensor chip, humidity measurement module based on digital humidity sensor chip, power monitoring module based on opticalcoupler, GPRS SMS alarm module based on MC35. Paper focuses on the various functions of the system based on OpenTCP. including network connectivity of embedded system, implementation of the embedded Web server, implementation of the system interactivity, Server gains network parameter function, network alarm function. In addition, the design of guardian software based on Windows and Linux operating systems are introduced.Finally, the functional modules of the system are tested, from the results, we know that the design of each module achieve the desired requirement.
