무인열차운행을 위한 유 · 무선 감시시스템 개발 현황

초록

As driverless train operation has been expanded, there is a growing need for onboard monitoring system for invasion into operational line, onboard security of operational train and passenger safety. Test lines and test rolling stocks are in operation about 12km between Illo and Daebul stations in Jeonlla-do in order to evaluate performance of wireless train control system and wire and wireless monitoring system is under development and test evaluation for trackside and onboard passenger safety. Wire monitoring system has been designed and produced in order to allow obtainment of images for monitoring trackside invasion and line maintenance workers. For wireless monitoring system, it is possible to transfer images between onboard and ground by using wireless system with 18GHz, the exclusive frequency band for wireless transmission of train images and commercial wireless system. This paper describes current development of wire and wireless monitoring system established on the Daebul test line.
