| 摘 要： | 针对单一类型传感器检测管道泄漏的局限性,本文提出了一种基于多声学传感器融合的管道泄漏检测方法.它将振动传感器和声音传感器相结合以获取泄漏点声波信号,通过对这两种声波信号提取某种特征量进行相应的融合计算推断出管道泄漏是否发生.实验结果表明,该种方法能有效地提高管道泄漏检测的准确性.

| Abstract: | Aiming at the deficiency of leak detection for pipelines based on single sort of sensors, this paper brings forward a method of leak detection for pipelines based on acoustic multi-sensors. It can obtain acoustic signals of leak location both from quiver sensors and from hydrophones, this method deduces whether the leakage happened or not by extracting a certain feature and fusing arithmetic according to the feature obtained before. The experiment results indicate, the method can greatly improve the accuracy in leak detection for pipelines. |
