铜丝绳在煤矿生产中的起着重要作用。针对钢丝绳的结构特点,研究分析了以漏磁检测原理为核心的钢丝绳断丝检测方法。为了提高检测信号分析精度和检测的可靠性,对采集到的断丝信号进行深入分析,采用小波分解、重构的方法来滤出高频低通等干扰信号,最终给出了监测信号频谱上断丝信号的定量识别方法。经反复实验,检测结果与实际情况基本一致,证明了该检测及分析方法的可行性。
Copper wire rope in coal production plays an important role. Aiming at the structural characteristics of wire ropes, the wire rope breakage detection method based on the principle of magnetic flux leakage testing is analyzed and studied. In order to improve the accuracy of signal detection and the reliability of detection, the broken signal was collected and analyzed by wavelet decomposition and reconstruction method to filter out the interference signals such as high-frequency and low-pass. Finally, Quantitative identification of broken wire signal. After repeated experiments, the test results are basically the same with the actual situation, which proves the feasibility of the detection and analysis methods.
