Abstract

The invention discloses an equipment fault diagnosis method and device. The method comprises the steps that acquiring noise data and vibration data of the surface of equipment; obtaining a corresponding data curve according to the noise data and the vibration data; judging whether the data curve is consistent with a model base line when the equipment runs normally or not, and if not, generating abnormal information; judging whether the abnormal information is fault information or not; if the abnormal information is fault information, marking the abnormal information as the fault information; and if the model base line is not the fault information, performing machine learning on the model base line and the data curve to obtain a new model base line. A fault diagnosis and prediction solutionbased on a local edge side system and through noise and vibration is constructed; continuous monitoring of equipment faults can be achieved only by detecting equipment noise and vibration data, and therefore accidental shutdown in the industrial production process is further reduced, the product yield is increased, and the industrial production cost is reduced.

Description

technical field [0001] The present application relates to the technical field of automatic equipment fault diagnosis based on machine learning, and in particular, relates to a method and device for equipment fault diagnosis. Background technique [0002] Generally, there will be sound or vibration during the operation of the equipment, and when there is a problem with the operation of the equipment, the sound and vibration will change. By observing these changes, experts can diagnose the location and cause of the abnormality of the equipment, and even predict the upcoming occurrence of the equipment. A malfunction that prevents the device from functioning properly. Due to the high traffic cost of data transmission, and some data (such as noise and vibration) that need to be used for equipment fault diagnosis or prediction usually have a large amount of data, the use of artificial intelligence machine learning is gradually inclined to the edge computing unit. [0003] In the...
