More Information
Summary:The utility model relates to a pipeline leakage monitoring device based on a distributed optical cable, which comprises a distributed demodulator, a pipeline and a temperature sensing optical cable, two ends of the distributed demodulator are respectively connected with the temperature sensing optical cable to form a loop, and the temperature sensing optical cable monitors the temperature around the pipeline. If the pipeline leaks, the temperature change detected by the temperature sensing optical cable is transmitted to the distributed demodulator, the distributed demodulator generates a corresponding temperature change curve, the whole temperature sensing optical cable is laid above or below the pipeline in parallel in the axial direction of the pipeline, and the distance between the temperature sensing optical cable and the wall of the pipeline is smaller than or equal to D, the value of D is 0.5-1m, and all laying positions of the temperature sensing optical cable form a sector ring area. According to the
