A design of a smart train interlocking system

초록

As a result of advanced radio communications technologies, some investigations are being in progress to apply those technologies to Train Control Systems. However, these investigations such as CBTC(Communication Based Train Control), AATC(Advanced Automatic Train Control) and ETCS(European Train Control System) level 3, are focusing on the train safety distance control between a preceding train and a succeeding train and using conventional interlocking systems. The interlocking system uses train circuits to control railway paths. To take full advantage of radio communications based train control systems, the interlocking system must use the radio communication technology instead of the conventional technology, track circuit. Because the radio communications transmits and receives some messages, the proposed interlocking system can use many data such as train IDs, train running direction, train running position and train running speed. But the conventional interlocking system uses only one data, train occupation data. So, we can say that the new interlocking system is more safe than the conventional interlocking system. This paper describes characteristics of new interlocking system, interlocking process of new interlocking system configuration, hazard identification, and organization of new interlocking system.
