선로내 작업 안전성을 높이기 위한 방호시스템 기술 개발

초록

It is necessary to have a maintenance of track and its equipment for safety and stability on the railroad transportation. In the paper, we examine the safety problems, protection functions and composition of protection system for safety within the track which RTRI developed. This system consists of a mobile business tool carried by each worker, a terminal of the control platform temporarily installed in the maintenance car, a connector attached to the existing signalling system and a central administrative device installed at the control center. GPS is used independently to detect positions of workers and maintenance cars. Each machine can correctly grasp the geometrical relations with other workers cars and other objects and their conditions based on the state information exchanged between the machines by the distributed control protocol, the track occupancy monitor information broadcast by the central administrative device and the line information. The protection system executes its functions on this basic structure.
