Abstract: The broken wire signal analysis and quantitative recognition is an interesting subject which may be performed by may or by computer, However, a man-machine cooperative system introduced in this paper is more reliable and more accurate in analysising and recognizing broken wire signal. Except the number of broken wires, the more information about .the rope condition may be gained from the man-machine cooperation.
