Abstract
In order to improve the intelligence and efficiency of railway signal maintenance, a method of knowledge integration and push for networked maintenance process was proposed. Firstly, the knowledge involved in maintenance service process was analyzed, and a method of knowledge integration model of networked maintenance process based on knowledge service process was built. Based on the analysis of the characteristics of railway signal maintenance knowledge, this paper proposes an ontology-based knowledge push mechanism through the description of maintenance knowledge scenarios in different dimensions. Finally, through the application of active push of equipment maintenance knowledge in a railway signal department, this method was proved to be effective in active maintenance knowledge push.
