  Abstract:In order to achieve the online high precision statistics of yarn defect quantity，aiming at the deficiencies of statistics yarn frequent defects with blackboard method and instrument testing method，on the basis of the diameter measuring principle of linear array CCD sensor，yarn frequent defect online measuring system is designed.Frequent defect quantity of yarn samples is counted in  experiment，and is compared with that of USTER evenness tester.The results show that the correlation coefficient between the statistical results of linear array CCD system and the statistical results of Uster evenness tester is 0.992，indicating that the fine ends,nubs and neps of the linear array CCD online detection system can accurately reflect the quality grade of yarn,and the linear array CCD online detection system has good realiability，high detection efficiency and high accuracy of yarn frequent defects.
Key Words:frequent defect；blackboard method；linear array CCD；sensor；yarn diameter；USTER evenness tester；correlation coefficient
