钢丝绳无损检测中的一些算法——信号的预处理和特征提取

SOME ALGORITHMS FOR NONDESTRUCTIVE TESTING OF WIRE ROPES——SIGNAL PRE-PROCESSING AND CHARACTER EXTRACTION

对应用于钢丝绳无损检测仪器中的算法进行了一些探讨和总结。并介绍了一些实用的信号处理和特征提取算法 ,包括可以实时运算的用于抑制干扰的滤波器和数据平滑算法及用于定量分析的差分超限数、绝对峰值、峰 -峰值。

The algorithms for nondestructive testing of wire ropes are discussed and summarized. The practical methods of signal pre processing (anti disturbance filtering, data smoothing) and character extraction (differential limitation, absolute peak value, peak to peak value, area of wave and self adaptive threshold adjustment) are introduced.
