基于负压波的输油管道泄露检测去噪处理

Negative Pressure Wave Based on the Oil Pipeline Leak Detection Denoising Treatment

基于负压波的输油管道泄露检测去噪处理可以将负压波法提取的泄露信号中大量的噪声通过邻域平滑、频域变换,小波分析等方法设置合理的参数滤除掉,结合模拟分析和现场应用准确的判断泄露位置。

Based on the oil pipeline leak detection denoising deal with negative pressure wave, negative pressure wave is extracted from the leak noise signal through many neighborhood smoothing, frequency domain transform, wavelet analysis methods, such as setting reasonable filter parameters. Accurate location of leaks can be determined by combination with simulation analysis and field application.
