LEAK DETECTION SYSTEM AND LEAK DETECTION METHOD
To provide a technique for accurately specifying a leaking position even in a case where a pipe length in a section where a leak is doubted is unknown.SOLUTION: A leak detection system 10 comprises a pipe length calculation unit 12 and a leaking-position specifying unit 13. Based on a second excited vibration reach time difference and a vibration propagation speed in piping 15, the pipe length calculation unit 12 calculates a pipe length of the piping 15 in an unknown section 18 (a first section). Based on a leak vibration reach time difference, the vibration propagation speed in the piping 15, and the pipe length of the piping 15 in the unknown section 18, the leaking-position specifying unit 13 specifies a leaking position in the unknown section 18.SELECTED DRAWING: Figure 3
【課題】配管のうち漏れが疑われる区間の配管長が未知な場合でも、漏れ位置を精度よく特定する技術を提供する。【解決手段】漏洩検出システム１０は、配管長算出部１２と漏れ位置特定部１３を備える。配管長算出部１２は、第２加振振動到達時間差分と、配管１５における振動伝搬速度と、に基づいて、未知区間１８（第１の区間）における配管１５の配管長を算出する。漏れ位置特定部１３は、漏れ振動到達時間差分と、配管１５における振動伝搬速度と、未知区間１８における配管１５の配管長と、に基づいて未知区間１８における漏れ位置を特定する。【選択図】図３
