철도 전용 무선망을 이용한 철도 승강장안전문 제어장치 설계

초록

The PSD(Platform Safety Door) operated in the history of urban railroads should be opened and closed in conjunction with the operation of the train, but until now, various problems have arisen due to the use of radio signals in the ISM band in conjunction with the train and the ground PSD control system. To solve this problem, this paper designed a system with improved safety, including LTE-R-based trains, ground controls, and interfaces, as well as adding train entry detection functions.
