| 摘 要： | 对基于声波的天然气泄漏检测定位进行了研究，介绍了基于声波法的天然气泄漏检测的实验设计方案与定位原理。利用EMD可以将分解得到的前几个包含主要信息的IMF处理后重新构造，而对于后几个IMF如果干扰的成分比较突出，可以直接将其滤除，进而进行定位以减少定位误差。并通过实验验证，所有结果均在指标要求的范围之内，且效果良好。

| Abstract: | An algorithm for gas pipeline leakage detection and location based on the acoustic method was stud- ied, including the experimental design scheme and location principle. The EMD can re-construct some IMFs which containing main information and can directly eliminate those IMFs with obvious interference factors so as to correctly locate the leakage. The experimental results show that all results can stay within the specifications along with good effects. |
