Railway Station Of Interlocking Table Intelligent Generation Method Research And Implementation

In the railway transport system, in order to ensure safety, signal, rail and road must be kept into a certain constraint relationship and the operation sequence, the constraint relationship and the operation sequence called interlocking. Essential meaning is putting switches routes and signals into centralized control and supervision.Interlocking table is the station signal equipment interlocking relationship of information, is the function of the description of signal control system of railway station, are the total basis of design station system function. For medium and railway station, especially hub station, due to the route of train and the locomotive are various, signal equipment interlocking relationship is complex, and therefore realizes the automatic generation of interlocking table has important significance. With the improving of the train speed and computer based interlocking control system of the rapid development and application, the station interlocking relationship of information support is more and more important, interlocking relationship has relation with the train station topological structure, station types and pattern, the train operation safety and work efficiency and so on, how to generate the accuracy of the information in the interlocking table in convenience way has become a very important problem.This paper with "railway signal expert system research and development" project of scientific research work, select railway station of interlocking table of intelligent generation method as research topic. This paper based on the analysis of the present situation of the domestic and abroad railway station signal topology structure formation generation and interlocking route algorithm, through the graph theory and railway signal interlocking relationship of theoretical analysis, design railway signal interlocking chart intelligent generation system development module, and use C++Builder for tool to achieve MS Visio second development.The system can through the figure connected to generate topology structure schematic station, according to equipment entity information, use interlocking related algorithm to complete the operations of interlocking relationship, and to generate interlocking table and save it to VSD files and database. The system design method and the development of prototype software, provide the reference for the actual system development and application.
