摘要
介绍了利用漏磁场原理检测钢丝绳断丝 ,磁桥回路测量钢丝绳磨损信号 ,并实现在一个传感器中对上述多种缺陷的综合检测。在信号处理方面 ,结合不同信号特征 ,设计了相应的电路和处理软件 。
The detection method and principle for wire ropes are proposed.According to the ferromagnetic charaterstic of the steel wire ropes,the defects of the steel wire ropes is detected by the magnetic method.The magnetic flux leakage method is adopted to test the broken wires of the wire ropes,the wear of the wire ropes is detected by magnetic bridge circuit method.All these methods are integrated into one detector.By designing the corresponding electronic circuit and signal processing software,the comprehensive defects is qantitatively inspected.
