BIT and case fusion based equipment fault diagnosis method and system

Abstract

The invention relates to a BIT and case fusion based equipment fault diagnosis method and system. The system comprises an equipment information collection module, a fault analysis and diagnosis module, a case analysis and diagnosis module, a fault processing module and a fault information management module; the equipment information collection module, the fault analysis and diagnosis module, the case analysis and diagnosis module and the fault processing module are connected successively; the fault information management module is in bidirectional connection with the fault analysis and diagnosis module, the case analysis and diagnosis module and the fault processing module; and the fault analysis and diagnosis module is connected with the fault processing module. An equipment BIT diagnosis is fused with a fault case diagnosis, an equipment fault is diagnosed in a manner that the BIT diagnosis plays a leading role and the fault case is used for inference and post supplement, and the fault diagnosing accuracy and efficiency of the equipment are improved.

Description

technical field [0001] The invention relates to the technical field of calculation and measurement, in particular to an equipment fault diagnosis method and system based on BIT and case fusion. Background technique [0002] With the wide application of new technologies centered on information technology in equipment, at present, most of the equipment adopts case-based fault diagnosis system, but the case-based fault diagnosis system has the shortcomings of too simple reasoning mechanism and poor adaptability, especially The disadvantages of the case-based fault diagnosis system will become more prominent when the diagnostic objects are complex, the fault knowledge scale is large, and the fault cases are limited. Therefore, the equipment is changed to a built-in test (BIT) system based on bus technology. The internal equipment measurement and control nodes of each subsystem in the BIT system are connected to the bus network through the bus interface circuit to form a system s...

AI Technical Summary

Problems solved by technology

However, the BIT system does not have the ability of reasoning and knowledge accumulation, and has the disadvantage of high false alarm rate

In actual support, it often occurs that the same BIT diagnostic conclusion corresponds to different fault causes, and the diagnostic conclusion is not obtained in time for troubleshooting, which brings maintenance challenges to equipment support personnel.
