Title:
METHOD AND APPARATUS FOR DETECTING GEARBOX FAULT
Document Type and Number:
WIPO Patent Application WO/2024/082103
Kind Code:
A1
Abstract:
A method for detecting a gearbox fault, comprising: acquiring detection data of a gearbox (S110); dividing the detection data into a plurality of groups of sub-band data (S120); acquiring a feature value of each group of sub-band data in the plurality of groups of sub-band data (S130); and according to all of the acquired feature values, determining whether the gearbox has a fault (S140). The accuracy of fault detection of the gearbox can be improved by means of dividing the detection data into a plurality of groups of sub-band data, and determining the fault state of the gearbox by means of each group of sub-band data, and the impact of noise on fault detection of the gearbox is reduced.
