Key Techniques of Pretreatment and Quantitative Identification of Broken Wire Detection Signal in Wire Rope

Detection of the wire rope directly relates to the personal and equipment safety. However, detection of the wire rope is confronted with some problems at present. For example, the detection result is affected by the running speed, the detection distance and the environment, the detection accuracy is not high, the versatility is not strong and so on. Therefore, key techniques of pretreatment and quantitative identification of broken wire detection signal in wire rope need to be studied. The study contents include the method of obtaining damage signal of wire rope broken wire, the pretreatment method of broken wire signal of wire rope, the detection signal feature extraction and quantitative recognition method and the key technology and implementation of detection software development. This study is of great significance to improve the safety of wire rope use.
