Research on construction technology and application of knowledge graph in equipment fault Diagnosis domain

In recent years, the construction technology of general knowledge graph (KG) has been developing continuously. The medical industry, manufacturing industry, financial industry and other industries have constructed domain KGs. The research of KG in the equipment field is mainly focused on general equipment knowledge, and the field of equipment fault diagnosis also needs to build its own domain KG. Combined with the definition of the general KG, the definition and construction process of the equipment fault diagnosis domain KG are expounded, the specific technical methods of each link of the construction process are summarized, and the application of the equipment fault diagnosis domain KG is explained, and some positive exploration is carried out for the subsequent construction of the equipment fault diagnosis domain KG.
