On the Design of Radio System for Communication Based Train Control System(2)

무선통신기반 열차제어시스템의 무선시스템 설계에 대한 검토(2)

CBTC(Communication Based Train Control) System has many superior train control performances than conventional track-circuit-based train control system with higher train operation efficiency, and less installation and maintenance cost. It is expected that CBTC will replace the conventional train control systems in near future. As CBTC has different mechanisms from conventional track-circuit-based train control systems in identifying train positions, and communicating information between train and ground facility, we have to pay a earful attention to making the interface between CBTC equipments and other signalling devices. This paper provides the construction of the interface between CBTC equipment and other signalling equipments such as TTC(Total traffic Control) system. ATO. electronic interlocking devices.
