| Abstract |
The mainline railway train control system can be classified into automatic train stop and automatic train protection. Automatic Train Protection (ATP) has been introduced and operated on mainline railways in Korea since 2003. The Lineside Electronic Unit(LEU) is one of the on-site ground facilities installed in block sections and is responsible for transmitting train control information through the Balise. It is designed to transmit train control information based on signal indication information on the block section track.
However, in Korea, the LEU and Balise are connected by a solid line, so that uplink data can only control short distances. In the event of a malfunction or inspection at a block section track, maintenance personnel must arrive at the site and perform the work directly on the trackside. This causes a delay in the movement of personnel to ensure normal functioning, and in the case of sections where trains are in operation, safety issues may arise, and work efficiency may decrease. In this paper, we present the results of a test analysis of a control device developed to enable remote control and monitoring of ground-based equipment, such as Balise. This development device can transmit ‘Interface-C’, which acts as an up-link interface between the lineside control unit (LEU) and Balise among ETCS Level-1 on-board signal device, over long distances. |
