자기센서를 이용한 새로운 열차위치검지기법의 가능성 연구

초록

It is very important to know the train location for shortening the headway, an efficiency of railway maintenance as well as the safe operation of trains. The reason of the train location detection is the control of train intervals between the railway stations and the train path control in the railway station yard. Therefore, the accurate detection of train location is very important technology in railway engineering. Nowadays, the technology of train location detection is the track circuits in wayside signalling block system and the wheel sensors in train. The CBTC(Communication based Train Control) system is used in urban railway recently. But the change of railway design is very difficult and its cost is very high since the CBTC system was imported in Korea. This paper deals with the feasibility of new train location detection method using magnetic sensors.
