摘要
对小波变换的基本理论进行了简要的阐述,特别是信号奇异性检测。并以天然气管道泄漏后获得的相关信号为对象。利用小波分析方法来分析信号的奇异性及奇异性位置,从而应用到天然气管线泄漏检测中,仿真实验证明了该方法对管道泄漏诊断的精度,同时也显示出小波在滤波、定位等方面的优越性。
This paper firstly introduces the properties of wavelet transform, especially detection of signal singularity. And pressure signal is obtained after leaking as research's target. Make use of wavelet transforms to analyze the singularity and location in detection of gas nature pipeline leakage. The result shows the wavelet singularity analytical is more efficient than other traditional signal analysis methods in filter and location.
