摘要 |
The present invention reduces production costs associated with a device that uses results of detection by a plurality of vibration detectors to detect a leakage position in a pipe.;A first time difference calculation unit 114 calculates a time difference Δt1 between the timing of detection of vibration that indicates the first vibration mode of a pipe P and the timing of detection of vibration that indicates a second vibration mode of the pipe P by processing a result of a measurement made by a first vibration detection unit 112. A second time difference calculation unit 124 calculates a time difference Δt2 between the timing of detection of vibration that indicates the first vibration mode of the pipe P and the timing of detection of vibration that indicates the second vibration mode of the pipe P by processing a result of a measurement made by a second vibration detection unit 122. A leakage position calculation unit 130 uses the time differences Δt1, Δt2, and a space interval I between the first vibration detection unit 112 and the first time difference calculation unit 114 to calculate a leakage position in the pipe P. |
