| 摘 要： | 采用小波包去噪方法解决漏磁信号的噪声抑制问题。针对软、硬阈值处理中存在的缺陷,提出了模糊阈值处理方法,应用该方法对采集的漏磁信号进行消噪处理。实验结果表明,与传统小波包的去噪效果相比较,模糊小波包降噪方法不仅较好地剔除信号中的噪声,而且保留了原始信号中的有效成分,是一种可行的方法。

| Abstract: | The fuzzy wavelet package transform is employed to solve the problem of noise reduction in the magnetic flux leakage（MFL） inspecting signals. Fuzzy threshold method is introduced for the limitation of soft and hard threshold. It is applied in the MFL inspecting signals noise reduction. The simulated results show that our fuzzy wavelet package transform has achieved the noise reduction better than that achieved by traditional wavelet package transform ,which is not only de-noising, but also retains effective composition in the original signal. It is a feasible way to process MFL inspecting signals. |
