The Study On The Subsystem Of Post Processing Of Faults Diagnostic Expert System For Turbo-generator

AbstractThis thesis's research work is based on a practical project of Faults Diagnostic Expert System For Turbo-generator for some power plant. The subsystem of post processing for the Expert System is studied and completed. The characteristic, function and achieving method of the subsystem are mainly discussed.Expert System developed in this project uses on-line and off-line data sources, and can diagnoses as many as 106 faults, taking on-line and off-line diagnostic reasoning which inherited and succeeded to each other. So its subsystem's characteristic lies in it is both exit of processing diagnostic results and entry to further continuous diagnosis, concerning practice use of the ES it also solves series of problems.Subsystem's main function include two:(1) Classifying and processing every diagnostic result.(2) Providing fault-sort management, dynamically real-time explanation, fault-remembering, fault query, report-printing, rank establishment, on-line help and so on, which are problems must be solved for increasing of the application effects of the ES.Taking multi-client operating mechanism into account, in this theis, more than 10 functions of the subsystem severed as client terminal; to the subsystem, whole design and every module design and data interface to other subsystem are developed; Subsystem is programmed with SQL Server 6.5 and Delphi 5.0 based on C/S. The subsystem has been debugged successfully and applied in practice. Practical application shows the design and method put up in this paper are indeed feasible.
