Abstract: Correlation analysis is an important method to recognize broken wire from testing the signal of steel wire rope. Based on character of testing signal, by means of correlation function of testing signal, cross-correlation between signal with broken wire and standard signal extracting from testing signal is performed by choosing best time-relay. The length of correlation window has significant influence on correlation coefficient, and reasonable resolution is presented. As a key index for gaining stable correlation character index, time-relay is researched. At last, testing signal is analyzed with correlation analysis method. Reliability of automotive recognition can be increased with correlation analysis method, cooperating with other recognition methods in time domain.
Key words: Steel wire rope, Best time-relay, Broken wire, Correlation analysis
