The Electromechanical Equipment Fault Diagnosis And Expert System Based-on Internet

With the development of large-scaled electromechanical system andsynthesized control system, the dependability of the system is more and moreimportant. And many kinds of new fault diagnosis technologies and methods areemerged constantly.ln this infOrmation epoch, the rapid development and good applicationprospect of Internet and LAN technology makes it a carrier to be various ofinformation. Remote condition monitoring and diagnosis based-on Internet/lntranet is a kind of combination mode in 21 century, which is welcome andregarded on the academe and industry. The opening software and hardwaresystem structure of Internet is recognized, and becomes a inevitable tendency.At present, our country's high speed computer network has developed day byday; The network technology has got extensive application in the diagnosing Thenetwork technology has got extensive application in the technology of diagnosis.Based on facts above, and aimed at the development tendency and presentsituation of the equipment condition monitoring and diagnosis, the paperadvanced Internet-based equipment remote condition monitoring and diagnosissystem.In the course of research, a few of technologies involved, which is the basisand guarantee fulfilled: 1 \ the technique of SCM(Simple Chip Microcomputer)driving modem; 2. design of the remote interface technique for SCM; 3 \ data issaved as Dbase form in SCM, 4. carried through the development of the remotefault diagnosis and expert system of electromechanical equipment, and realizedBrowser/Server computing mode and expert system perfect combination. At thesame time, the paper discusses how to design the software of the Internet-baseddiagnosis system and the Intranet. At last, the paper discusses the networksecurity problem.The research of the key technique is the base and guarantee of the functionof the system.The advance of the technologies of the Internet-based equipment remotecondition monitoring and diagnosis system makes academe and enterprisesovercome the differences of the time and the places, solves the difficulty of lackInternetspecialized personnel, enriches the research of the theory, and has the remarkable social and economic results.
