Device and method for estimating performance degradation of equipment based on inspection system

Abstract

The invention relates to a device and a method for estimating performance degradation of equipment based on an inspection system. The device comprises a vibration analyzer and a PC (Personal Computer) machine, wherein a data colleting and signal processing module, a performance degradation estimating and diagnosing module, an information interacting module and a model training module which are mounted on the vibration analyzer and the PC machine are used for implementing the estimation; the data colleting and signal processing module is used for finishing the vibration signal data collection and extracting feature vectors; the performance degradation estimating and diagnosing module is used for performing information fusion on the feature vectors, estimating the performance index of the equipment by combining model parameters and outputting an estimating result; the information interacting module is used for finishing the interaction between the feature vectors and the model parameters; and the model training module is used for establishing an equipment performance degradation estimating model and outputting the model parameters. According to the device provided by the invention, the vibration analyzer is used for accurately and timely monitoring and estimating the performance degradation state of the present equipment on an industrial field; the device can be used for forecasting the performance trend of the equipment; excellent reference and basis are supplied to the equipment management and maintenance; the running reliability of the equipment is enhanced; and the maintenance cost of the equipment is lowered.

Description

technical field [0001] The present invention relates to equipment condition monitoring and fault diagnosis system, more specifically, relates to an equipment condition monitoring and performance degradation evaluation device and method based on a patrol inspection system. Background technique [0002] Equipment condition monitoring and fault diagnosis technology first originated in the United States. In 1967, under the guidance of NASA, the United States "Mechanical Failure Prevention Group (MFPG)" was established under the auspices of the United States Naval Research Office (ONR). The existing condition monitoring and fault diagnosis systems are mainly in three typical forms: regular monitoring and diagnosis system, stand-alone online fault monitoring and diagnosis system and distributed monitoring and diagnosis system. The deficiencies of these systems are analyzed as follows: [0003] 1) Regular monitoring and diagnosis system: The regular monitoring and diagnosis system ...

AI Technical Summary

Problems solved by technology

The disadvantage is that each enterprise has established a relatively independent monitoring and diagnosis local area network, which can only achieve the information sharing of each monitoring and diagnosis system within the enterprise, and there is no connection between enterprises

However, the traditional fault diagnosis method is to make a judgment on the presence or absence of the fault, and cannot give the process of the fault from scratch. , it is also easy to increase the maintenance cost of the equipment and reduce the economic and social benefits of the enterprise
