| 摘 要： | 对小波变换的理论进行了简要的介绍,特别是信号的奇异性检测,并以输油管道泄漏后获得的负压波信号为对象,利用小波变换方法来分析信号的奇异性及奇异性位置。应用到输油管道泄漏检测中,实验证明了该方法对管道泄漏诊断的精度,同时也显示出小波分析在泄漏定位方面的优越性。

| Abstract: | The theory of wavelet transform is introduced briefly,especially the detection of signal singularity.The negative pressure signal is obtained after leakage of oil pipeline by making use of wavelet transformation to analyze the singularity and location of the signal.The result shows that the wavelet singularity analysis is more efficient than other traditional signal analysis methods for detecting the leakage location. |
