Abstract

The invention provides a fault diagnosis method and device based on a knowledge graph, equipment and a medium. The method comprises the steps that when a device breaks down, the feature vector of a current fault device is determined based on a device fault knowledge graph, and the device fault knowledge graph is constructed based on fault diagnosis data of historical fault devices; determining the similarity between the feature vector of the current fault device and the feature vector of each historical fault device in the device fault knowledge graph; and determining the diagnosis result of the historical fault equipment corresponding to the highest similarity as the diagnosis result of the current fault equipment, and pushing a solution corresponding to the diagnosis result to the current fault equipment. The accuracy of equipment fault diagnosis can be improved, and the equipment fault diagnosis effect is improved.

Description

technical field [0001] The embodiments of the present application relate to fault diagnosis technology, and in particular to a knowledge map-based fault diagnosis method, device, equipment, and medium. Background technique [0002] Equipment fault diagnosis is to diagnose the operating status and abnormal conditions of the equipment, and provide a basis for equipment fault recovery based on the diagnosis results. [0003] At present, when performing fault diagnosis on equipment, the operation data during the operation of the equipment is often obtained, and the operation data is matched with the artificially formulated fault rules to determine the real cause of the equipment failure; or based on the operation data during the operation of the equipment Calculate key indicators and determine the real cause of equipment failure based on key indicators. However, the diagnostic accuracy of the above-mentioned fault diagnosis methods is poor, resulting in poor diagnostic effect o...
