The present invention relates to a bicycle monitoring system, which is possible to monitor deformation or damage to a bicycle frame during driving or non-driving of a bicycle. The bicycle monitoring system of the present invention includes: one or more optical fibers (20) inserted thereinto or attached to an outer surface of one side along a longitudinal direction of a bicycle frame (10) forming a frame of the bicycle; one or more optical fiber bragg grating sensors (30) provided to form a bragg grating on the optical fiber (20) and reflect only a wavelength corresponding to the grating; and a control unit (40) determining whether the bicycle frame is deformed or damaged through a change of the wavelength reflected from the optical fiber bragg grating sensor (30).

    본 발명은 자전거의 운행 또는 비운행 중 자전거프레임의 변형이나 손상 등을 감시할 수 있도록 한 자전거 모니터링 시스템에 관한 것이다. 본 발명의 자전거 모니터링 시스템은 자전거의 골격을 이루는 자전거프레임(10)의 길이방향을 따라 내부에 삽입 또는 일측 외표면에 부착되는 하나 이상의 광섬유(20); 상기 광섬유(20) 상에 브래그 격자를 형성하여 상기 격자에 대응하는 파장만을 반사하도록 구비되는 하나 이상의 광섬유 브래그 격자센서(30); 상기 광섬유 브래그 격자센서(30)에서 반사된 파장의 변화를 통해 자전거프레임의 변형이나 손상여부를 판단하는 제어부(40);를 포함하여 이루어진다.
