Zusammenfassung: | To provide a leakage detection method capable of detecting a position of a mobile body in a pipe line in which a fluid having pressure flows and a leakage position corresponding to this position, and the mobile body and a leakage detection device that perform this method.SOLUTION: A detection start point B1, a detection end point B2, curved parts C1-C3 to be a detection reference point, and pipes A1, A2 are set in a pipe line A. A movement start time t0 and a movement stop time t4 for a mobile body 10 are recorded. By making direction data for the mobile body recorded in the process of movement of the mobile body, a time when the mobile body passes the detection reference point, obtained from pipe material change data, the movement start time, and the movement end time associate with a laying drawing, a position of the mobile body in the pipe line in association with each time is estimated. Based on sound data obtained by collecting and recording sound in the process of movement of the mobile body, positions of leakage positions D1-D3 are detected according to the position of the mobile body corresponding to the time obtained by recording the sound.SELECTED DRAWING: Figure 2
【課題】圧力を持った液体が流通する管路に於ける移動体の位置と、この位置に対応させて漏洩位置を検知することができる漏洩検知方法と、この方法を実施する移動体、漏洩検知装置を提供する。【解決手段】管路Aに検知開始点B1、検知終点B2、検知基準点となる曲がり部C1~C3及び管A1、A2を設定する。移動体10の移動開始時刻t0、移動停止時刻t4を記録する。移動体が移動する過程で記録した移動体の向きデータ、管材質の変化データから得られた移動体の検知基準点通過時の時刻と、移動開始時刻、移動停止時刻を敷設図に対応させることで、時刻毎に対応させた、管路に於ける移動体の位置を推定する。移動体が移動する過程で集音して記録した音のデータに基いて、音を記録した時刻に対応した移動体の位置によって、漏洩位置D1~D3の位置を検知する。【選択図】 図2 |
