- Abstract:
- -Underground pipeline has been extensively utilized for long-distance water transmission, and the safety monitoring and early warning of water transmission pipeline leakage has been concerned. Based on the extraterritorial water distribution project in Jiaxing, a real-time online leakage monitoring system is built by introducing distributed optical fiber sensing and quasi-distributed underwater acoustic detection methods. The application results demonstrate that these two monitoring techniques can accurately located leakage points with a volume exceeding 20 L within 30 seconds, and the positioning error is no more than 10 m.
