레일절손 검지 시스템 및 이를 이용한 레일절손 검지방법에서, 상기 레일절손 검지시스템은 측정위치 설정부, 신호 측정부, 데이터 처리부 및 판단부를 포함한다. 상기 측정위치 설정부는 기준지점을 포함한 서로 다른 복수의 측정위치들을 설정한다. 상기 신호 측정부는 열차가 상기 기준지점을 포함한 측정위치들을 통과하는 경우, 각각의 측정위치들에서의 진동 신호들을 측정한다. 상기 데이터 처리부는 상기 측정된 진동 신호들에 대하여 특정 주파수 대역에서의 최대값을 도출한다. 상기 판단부는 상기 도출된 최대값들을 바탕으로, 상기 측정위치들에서의 진동 신호의 변화량을 연산하여 상기 기준지점에서의 레일 절손의 여부를 판단한다.

    In a rail fracture decision system (10) and a method for deciding rail fracture using the rail fracture decision system (10). The rail fracture decision system (10) includes a measuring position setup part (100), a signal measuring part (200), a data processing part (300) and a decision part (400). The measuring position setup part (100) is configured to determine a plurality of measuring positions having a reference point, and the measuring positions are different from each other. The signal measuring part (200) is configured to measure vibration signals at each of the measuring positions, when a train passes through the measuring positions having the reference point. The data processing part (300) is configured to calculate a maximum value at a predetermined frequency range on the measured vibration signals. The decision part (400) is configured to calculate variation of the vibration signals at the measuring positions, based on the calculated maximum values, and to decide whether a rail is fractured at the reference point.
