Abstract

The invention discloses a mechanical failure state monitoring method based on gray relational analysis and a method thereof. The system comprises the components of a data acquisition module which is used for acquiring state data of a machine; a data processing module which is used for performing preprocessing on the acquired state data and processes the state data to a vector; a data analyzing module which analyzes the acquired vector through a gray relational analysis method and determines a mechanical fault state; and a result display module which displays a result that is analyzed by the data analyzing module. Compared with the prior art, the mechanical failure state monitoring system based on gray relational analysis and the method thereof have advantages of settling problems such as non-unique correlation value caused by resolution coefficient influence in a traditional method, using the gray relational analysis method as a mechanical fault state monitoring method, effectively improving accuracy and reliability of the mechanical failure state monitoring result, and realizing high practicability, wide application range and easy popularization.

Description

technical field [0001] The invention relates to the technical field of mechanical fault state monitoring, in particular to a mechanical fault state monitoring system and method based on gray-scale correlation analysis. Background technique [0002] Mechanical fault state monitoring is a technology based on the current and historical state information of equipment and using relevant analysis methods to quantitatively and qualitatively analyze the state of machinery. During the operation of machinery, there is no definite mapping relationship between faults and symptoms, so the machinery can be regarded as a complex gray system. [0003] As an important part of gray theory, gray relational analysis method is widely used in the field of mechanical fault monitoring and has achieved good results. However, the traditional gray relational analysis method has problems such as the correlation value is affected by the resolution coefficient and is not unique, the discreteness of the ...
