| Abstract: | 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. |
