Design Study on the Distributed Electronic Interlocking of Korean Radio-based Train Control System

초록

The Communication Based Train Control (CBTC) system reports the real-time train location report and transmits the movement authority through radio communication, and it shall increase railway capacity by allowing the high-density train control through high information transmission amount between the wayside ATP/ATO and the onboard ATP/ATO. Also, it shall reduce the maintenance cost because it does not use the existing track circuits. This paper deals with the distributed Electronic Interlocking (EI) which is the subsystem of the Korean Radio-based Train Control System (KRTCS) which is developing for the purpose of the driverless operation. The difference between the EI system of KRTCS and the EI of the existing Fixed Block System (FBS) is receiving the train location information through the ATP and decentralized structure which is separated a central device and a station device. Also, the EI system of KRTCS is designed for the immediate applying to the KRTCS through minimal changes of the existing EI.
