摘要
为解决燃气管道出现泄漏的问题,研究了基于小波分析的燃气管道泄漏检测技术以及确定具体泄露位置的方法。通过对小波分析的消噪技术进行初步分析,选择合适的尺度来破坏消噪信号,并通过燃气管道检测定位实例验证了该方法的准确性和有效性。该方法的原理是利用小波分析捕获和分析压力波的突降点,从而确定管道泄漏点的准确位置。
To solve the leakage of gas pipeline, this paper studies the leakage detection and positioning technology based on wavelet analysis, analyzes the noise suppression technology of wavelet analysis, select appropriate scales to destroy the escape signal, verify the accuracy and effectiveness of the gas pipeline detection positioning example, wavelet analysis is used to capture and analyze the sudden drop point of pressure wave to determine the accurate location of pipeline leakage point.
