Remote Intelligent Monitoring, Diagnosis, Maintenance Technology And Systems Research

Manufacturing system is becoming more and more complicated, automated and intelligent, and the importance of rapid diagnosis and maintenance technologies is obvious which ensure the security and reliability of the manufacturing system. The Remote Monitoring, Diagnosis and Maintenance System (RMDMS) is the next generation system, supported by information technologies, and provides rapid maintenance of complicated devices from the remote.This paper brought out the concept model of the RMDMS, it was divided into five layers, which showed the complicated information streams of RMDMS and all kinds of complicated knowledge and the implementing methods used. The RMDMS was distributed, and could be divided into Work Fields and Diagnosis and Maintenance Center, the former acquired and supplied the latest data of the complicated devices, the latter supplied all kinds of diagnosis and maintenance resources for the work fields; the RMDMS was the integration of several subsystems logically, which working in coordination to show the functions of condition monitoring, diagnosis and maintenance, resources marshalling and communication. The prototype system applied the idea of O-O, adopted the COM technology, Windows Sockets, Direct Show Package, and Multicast of IP messages. Also it adopted the CBR (Case Based Reasoning) technology to design a manual for the users to find the fault rapidly. The whole RMDMS had received good effects in experiments.
