| 摘 要： | 采用漏磁法对输油管道进行无损检测时,采集的漏磁信号具有数据量大和附带大量噪声的特性.为了去除信号中夹杂的噪声,采用小波变换中的Mallat算法对漏磁信号进行处理,使信号便于储存和分析.通过信号处理实验,取得了良好的效果.

| Abstract: | As the magnetic flux leakage(MFL) method is used to non-destructive inspection of long-distance ferromagnetic pipelines,the inspection signals derived with MFL method often contain a great deal of noise.Based on the Mallat algorithm of wavelet transformation,the MFL signal can be processed efficiently in order to be analyzed and stored.The Mallat algorithm has proved to be highly effective through a lot of experiments. |
