摘要
提出了跳变系统检测的卡尔曼滤波算法，与钢丝绳无损检测信号特征相对应，设计了钢丝绳断丝定量识别的多重假设检测方法，克服了差分超门限方法不能考虑背景噪声、测量噪声及误判率的不足，可以在线监测钢丝绳状态。
A Karmann wave filtering algorithm is proposed for testing of a jump change system. In correspondence to the signal characteristics for non-destructive testing of wore-rope, a multiple hypothesis testing method is designed for quantitative identification of broken wires. It can be used for on-line monitoring of wire-rope, and it has overcome the disadvantages of difference transfinite method which does not taken into consideration of background noise, measuring noise and law of errors.
