초록

열차 운행의 정확성과 안정성을 위하여 열차와 열차이동 주변환경 사이의 통신은 필수적인 요소이다. 열차 운행을 지원하기 위해서는 열차와 열차이동 주변 환경 사이에 측정/감시 등을 목적으로 사용되는 센서와 열차 간의 통신 구조와 성능의 분석이 요구된다. 본 논문에서는 이동 중에 있는 열차가 열차궤도 주변에 있는 각종 센서장치로부터 측정된 열차운행 및 환경 정보를 효과적으로 수신하고 이를 열차 데이터 관제 센터로 전송하는 LTE-R 기반의 철도 센서네트워크에 대한 성능을 분석하고 철도 센서 네트워크 구축에 필요한 구축 조건을 제시한다.

The communication between train and it's moving environments is considered as a necessity factor to support accuracy and safety for operation of train. Communication structure and performance between sensor and train used to measure and monitor between train and it's moving environments is required in operation of the train. In this paper, railway sensor network based on LTE-R is described and analyzed for moving train to support effective measure operation and environment data from various sensor devices located through railway and then transfer the data to data control center. Finally, implementation requirement for railway sensor network is suggested.
