Title:
ENGINEERING MACHINERY FAULT EARLY WARNING METHOD AND APPARATUS, AND ENGINEERING MACHINERY
Document Type and Number:
WIPO Patent Application WO/2022/267879
Kind Code:
A1
Abstract:
Provided in the present application are an engineering machinery fault early warning method and apparatus, and an engineering machinery. The method comprises: acquiring historical usage data and historical operation data of a target engineering machinery; compiling statistics on the occurrence frequency and the occurrence time of a preset fault keyword on the basis of the historical usage data; performing collaborative filtering on the historical operation data on the basis of the occurrence time of the preset fault keyword in the historical usage data, so as to determine an abnormal operation parameter; predicting fault prediction data of the target engineering machinery in the next operation period on the basis of the occurrence frequency and the occurrence time of the preset fault keyword, and the abnormal operation parameter; and performing fault early warning on the basis of the fault prediction data. By means of using the usage conditions and subjective evaluation of an engineering machinery that are fed back by a user of the engineering machinery and combining same with corresponding operation data of the engineering machinery, an anomaly or a fault with a fault risk is accurately positioned, and then fault early warning is performed in a timely manner, thereby improving the accuracy of fault early warning, facilitating the timely maintenance of the engineering machinery, and prolonging the service life thereof.
