Electric power communication system defect fault order sending method and device based on knowledge graph

The invention discloses an electric power communication system defect fault order sending method and device based on a knowledge graph. The method comprises the steps of collecting defect fault alarm information of an electric power communication system; extracting one or more target named entities from the defect fault alarm information; inputting each extracted target named entity into a pre-constructed power communication operation and maintenance knowledge graph, and outputting an associated named entity of each target named entity and an association relationship between each target named entity and the associated named entity; according to the target named entity, the associated named entity and the association relationship between the target named entity and the associated named entity, determining one or more defect fault tags, with each defect fault tag corresponding to one defect fault; and generating maintenance work order information of the corresponding defect fault according to the determined def
