A railway station interlocking table external route generation method based on template segment splicing

Abstract

This invention provides a method for generating off-table routes for railway station interlocking systems based on template fragment splicing, belonging to the field of intelligent railway station technology. The method involves obtaining the existing route list, constraint set, and key section set of a railway station; using fragment extraction and attribute calculation methods to obtain a template fragment library and multi-level indexes; recalling a candidate fragment set based on the template fragment library and multi-level indexes; calculating the matching kernel value of each fragment in the candidate fragment set based on the key section set and constraint set; aligning and splicing the fragments in the candidate fragment set according to the matching kernel value to obtain complete candidate routes; and verifying and calculating the confidence level of the complete candidate routes based on the constraint set to obtain an off-table route list and a traceable evidence chain. This invention solves the problems of low accuracy due to reliance on drawings, large enumeration space, lack of unified confidence level ranking, high cost of manual template maintenance, and lack of traceable evidence chains in existing technologies.
