본 발명은 소리 기반의 열차 운행 상황 모니터링 시스템에 관한 것으로, 이는 열차 선로에 접촉 설치되어, 열차 운행에 의해 발생되는 열차와 선로의 금속 마찰음을 집음하는 소리 집음부; 상기 금속 마찰음의 소리 발생 패턴을 검출하는 소리 분석부; 상기 금속 마찰음의 소리 발생 패턴을 기반으로 열차 종류, 열차 위치 및 이동 속도를 확인하고, 상기 확인 결과를 기반으로 열차 운행 상황을 유추하는 운행 상황 확인부; 및 상기 열차 운행 상황을 안내하는 안내 정보를 생성 및 출력하되, 상기 열차 운행 상황이 기 설정된 비정상 상태에 해당되면, 비정상 상태 발생을 통보하는 경보 정보를 즉각 생성 및 출력하는 운행 상황 안내부를 포함할 수 있다.

    The present invention relates to a sound-based train operating condition monitoring system, which may comprise: a sound collection unit installed to be in contact with a train track and collecting metal friction sound between a train and the train track generated by train operation; a sound analysis unit for detecting a sound generation pattern of the metal friction sound; a train condition checking unit which checks a train type, a train location, and a moving speed based on the sound generation pattern of the metal friction sound, and infers a train operating condition based on a checked result; and a driving condition guide unit for generating and outputting guide information for guiding the train operating condition, and when the train operating condition corresponds to a preset abnormal condition, immediately generating and outputting alarm information of notifying the occurrence of the abnormal condition.
