초록
철도에서 사용되는 열차위치검지기술은 레일의 전기회로를 구성하여 감지합니다. 이를 위해서는 많은 현장 설비의 설치와 지속적인 유지보수가 필요합니다. 따라서 건설비 및 유지관리비를 절감할 수 있는 대체기술이 필요합니다. 또한 최근 적용된 CBTC시스템에서 열차의 위치를 감시하기 위한 백업시스템으로 활용할 수 있는 대체기술의 개발이 요구되고 있다. 최근 광케이블 기술의 발달로 활용 가능성이 높아져 철도 전 노선에 철도전용광통신망을 구축하였으며, 광케이블은 전송속도가 매우 빠르고 전송오류가 1/100억에 불과하기 때문에 고속 데이터 전송과 높은 신뢰성이 요구되는 데이터 전송분야에서 많이 사용됩니다. 본 논문은 이를 활용하여 열차의 위치를 감지할 수 있는 시스템을 개발 및 적용하는 방법을 제안하는 데 목적이 있습니다.
Abstract
Train position sensing technology used on railways constructs and detects electrical circuits on rails. This requires the installation of many field facilities and constant maintenance. Therefore, there is a need for alternative technologies that can reduce construction costs and maintenance costs. In addition, there is a need to develop an alternative technology that can be used as a backup system for monitoring the location of trains in the recently applied CBTC system. With the recent advancement of optical cable technology, the possibility of utilization increases and a railroad-only communication network is being established on all routes of the railway. Fiber optic cables are very often used in data transmission fields that require high-speed data transmission and high reliability because the transmission speed is very fast and the transmission error is only one tenth of a billion. The purpose of this paper is to propose a method for developing and applying a system that can detect the location of a train by utilizing this.
