Industrial equipment fault management method, device and equipment based on knowledge graph

The invention discloses an industrial equipment fault management method, device and equipment based on a knowledge graph. The method comprises the following steps: acquiring equipment data; based on a knowledge extraction strategy, obtaining equipment operation and maintenance entity related information from the equipment data, and based on a disambiguation strategy, performing disambiguation processing on first target equipment operation and maintenance entity related information corresponding to semi-structured and non-structured data in the equipment data to obtain disambiguated entity information, the entity information comprises entities, entity attributes and relationships among the entities; performing similar entity information aggregation on the entity information in the structured data and the disambiguated entity information to obtain a knowledge network; based on a fusion strategy, fusing the historical knowledge base and the knowledge network to obtain a knowledge graph; and if the fault data of
