The present invention relates to a rail track inspection system and a method for the same and, more specifically, to a rail track inspection system and a method for the same, having improved accuracy by dividing outer noise and vibration generated in a rail track. According to the present invention, the rail track inspection system includes: first and second optical cables adjacent to each other and arranged on both sides of the rail track; and a control unit individually transmitting an optical pulse signal to the first and second optical cables and receiving a first scattering signal and a second scattering signal on the optical pulse signal generated due to the vibration while the first optical cable and the second optical cable are individually passed. The control unit calculates a first discrimination value and a second discrimination value, on each of the first scattering signal and the second scattering signal and determines a generation point of the vibration in accordance with whether the first discrimination value and the second discrimination value are in a critical range. Each of the first discrimination value and the second discrimination value is defined as a variable in accordance with the lineal distance from the first and second optical cables from the generation position of the vibration.

    본 발명은 선로 양측에 인접하게 배치되는 제1 및 제2 광 케이블들 및 상기 제1 및 제2 광 케이블들로 광 펄스 신호를 각각 전송하고, 상기 제1 및 제2 광 케이블을 각각 경유하는 동안 진동에 의해 발생하는 상기 광 펄스 신호에 대한 제1 산란 신호 및 제2 산란 신호를 수신하는 제어부를 포함하되, 상기 제어부는, 상기 제1 산란 신호 및 상기 제2 산란 신호 각각에 대한 제1 판별값 및 제2 판별값을 연산하고, 상기 제1 판별값 및 상기 제2 판별값이 임계 범위 내인지 여부에 따라 상기 진동의 발생 지점을 판단하며, 상기 제1 판별값 및 상기 제2 판별값 각각은, 상기 진동의 발생 위치로부터 상기 제1 및 상기 제2 광 케이블들까지의 직선 거리에 따라 가변되는 변수로 정의되는 것을 특징으로 하는 선로 검사 시스템 및 방법에 관한 것이다.
