The invention belongs to the technical field of
rail transit vehicles, and discloses a
rail transit vehicle fault intelligent diagnosis and maintenance service recommendation
system based on a
knowledge graph, and the service recommendation
system is composed of a
rail transit vehicle fault detection module, a
knowledge graph construction and updating module, and a maintenance service recommendation module. According to the method, efficient, accurate and real-time monitoring and fault diagnosis of the vehicle state are realized through a
fault detection algorithm, powerful data support is provided for intelligent fault diagnosis through a constructed comprehensive, dynamic and highly integrated rail transit vehicle
knowledge graph, a reliable knowledge basis is provided for maintenance service recommendation, and the reliability of fault diagnosis is improved. The method greatly improves the safety and maintenance efficiency of the rail
transit system, accurately generates and recommends an
optimal maintenance service scheme through a maintenance service recommendation
algorithm, achieves the intelligent recommendation of the maintenance service, improves the maintenance efficiency to the maximum degree, and reduces the operation cost.
