Abstract: PURPOSE:To allow performing a proper, fast fire fighting action in the early stages of a fire by a method wherein pulse light emitted into optical fiber sensors arranged along the sealing part of a floating tank,and the distances and temperatures of the sensors are calculated and indicated according to the Raman-backscattered light returning from the optical fiber sensors. CONSTITUTION:When pulse light G is emitted from a laser oscillator 4 into optical fiber sensors 2 that are arranged along the sealing part of a floating tank 1, the distances and temperature of the optical fiber sensors 2 are calculated by an arithmetic unit 11 according to the Raman-backscattered light returning from the optical fiber sensors 2 and the temperatures of the optical fiber sensors 2 and displayed on an indicator 17. Therefore, a fire can be detected from the rise in the temperature of the optical fiber sensors and the locations of the sensors whose temperatures rise. If the optical fiber sensors are arranged zigzag, the lead wires is hard to break and more accurate locations can be detected because the distances are lengthened. Furthermore, an alarm signal can be output through a fire prevention monitoring panel 18 according to the calculated results.
