In this paper, we study the communication based train control technology which has been improved for the railroad operation efficiency. All the signalling systems currently used in Korea are track circuit based train control systems, which train mobility and safety are considered on. When it comes to the recent abroad trend, development for communication based train control system, which arises new paradigm in the field of high density train separation, have been promoted. Considering the urgent necessity to develop the above mentioned technology, we would like to propose the research and development of communication based train control system and the present domestic and foreign statuses of on-board equipment development. In this paper, therefore, we had been developed localization on-board equipment of communication based train control system, which is the key construction of train control systems. For its verification, we accomplished installation and yard test on-board equipment of communication based train control system on Bundang-line's EMU(Electrical Multiple Unit).
본 논문에서는 철도의 운영효율을 향상시킬 수 있는 무선통신에 기반을 둔 열차제어기술에 대해 연구하였다. 현재 국내에서 사용되고 있는 신호시스템은 궤도회로 기반의 열차제어시스템으로서 열차의 이동성과 안정성을 고려하여 사용한 기술이다. 최근의 세계적 추세는 열차간격을 고밀도로 제어하기 위해 새로운 패러다임으로 떠오르고 있는 무선통신기반 열차제어시스템이다. 국내에서도 이에 대한 기술 확보가 요구되며, 이에 따른 무선통신기반 열차제어시스템의 연구개발을 추진하였다. 본 논문에서는 열차제어시스템의 구성 중 핵심적인 요소인 차상제어장치를 개발하였고, 이를 수도권 광역전철중의 하나인 분당선의 전동차에 설치하여 시험한 결과를 설명하고 있다.
