Universal phm application configuration method and device

Abstract

The invention relates to a general PHM (prognostic and health management) application configuration method and system. The general PHM application configuration method includes receiving a signal transmitted from a to-be-tested hardware device; receiving a signal analyzing configuration command, and subjecting the signal to at least one signal analyzing configuration according to the signal analysis configuration command; receiving a characteristic extracting configuration command, and subjecting the signal to at least one characteristic extracting configuration according to the characteristic extracting configuration; receiving a target business configuration command, and carrying out at least one target business configuration correspondingly according to the target business configuration; receiving an algorithm configuration command, configuring corresponding algorithms for signal analysis, characteristic extraction and corresponding target business according to the algorithm configuration command; according to the algorithms configured to different combinations correspondingly, acquiring target diagnosis results. By a series of configuration commands, the PHM system application is built rapidly. By configuration of at least one signal analysis, characteristic extraction and target business, rapid contrastive analysis on effects of multiple architectures and algorithms of the PHM application to specific objects is promoted, and PHM application configuration efficiency is high.

Description

technical field [0001] The invention relates to the field of fault prediction and health management, in particular to a general-purpose PHM application configuration method and system. Background technique [0002] PHM (Prognosis and Health Management, failure prediction and health management) is a system that monitors information such as the product's use environment, working conditions, and component status in real time to perform system status / fault diagnosis and prediction, and realize product remaining life prediction and failure. Positioning, scientifically and rationally arrange preventive maintenance activities, in order to minimize accidental failures and improve product reliability. [0003] Traditional PHM application research is basically centered on the object, and the developed PHM system is very specific. For the PHM application of specific objects, it is often necessary to try different methods such as feature extraction and state evaluation to test the perfo...

Problems solved by technology

[0003] Traditional PHM application research is basically centered on the object, and the developed PHM system is very specific. For the PHM application of specific objects, it is often necessary to try different methods such as feature extraction and state evaluation to test the performance of various methods and choose the most suitable method. The traditional method is to directly build the software and hardware system, resulting in high cost of hardware replacement after poor application effect in the later stage, difficulty in changing the software system, and low configuration efficiency
