Research on emergency handling of marshalling station control system based on knowledge graph

At present, most of the knowledge about the emergency handling process of marshalling station control system is scattered in the sporadic knowledge base such as railway regulations, system specifications and expert experience, which not only brings inconvenience to the emergency handling of the marshalling station control system during operation, but also brings great inconvenience to the operator. Due to the scattered and complex emergency handling process of marshalling station control system, this project intends to adopt a combination of top-down and bottom-up methods, and establish a construction method of knowledge graph of emergency handling process of group station control system based on the combination of top-down and bottom-up. On this basis, the method of knowledge extraction, knowledge storage and knowledge graph is used to visualize the fault data set during the operation of marshalling station control system. On this basis, using Cypher language, the emergency processing flow of marshalling station control system when failure occurs during operation is realized. It is found that the knowledge graph of the fault emergency handling process of the marshalling station control system constructed can effectively realize the structured storage and visual display of the fault emergency handling process, and the query method of the fault emergency handling process scheme of the marshalling station control system established can realize the corresponding matching of fault characteristics. The research results of this project will provide theoretical basis and technical support for the emergency treatment of marshalling station control system under the fault state.
