Abstract:In order to improve the accuracy and grading level of yarn defect detection，the principle and characteristics of capacitive detection and photoelectric detection are introduced，and the detection technology based on dual sensor fusion is proposed.The design，working principle and advantages of capacitive detection circuit，photoelectric detection circuit，CAN communication circuit and processing software flow of main controller to dual sensor fusion yarn defect detection technology are described in detail.Based on dual sensor fusion technology，a dual sensor fusion yarn defect detection system is developed and used to test 14.7 tex compact spinning cotton yarn.It is pointed out that the yarn defect detection technology based on dual sensor fusion，combining the advantages of capacitive detection and photoelectric detection，can obtain the yarn defect information only through one detection，reduce the damage to the yarn body by multiple sensors or multiple measurements，and can provide more accurate and comprehensive detection information for yarn defect detection.However，dual sensor fusion yarn defect detection technology can’t make judgments on plant fibers such as leaf chips and heterochromatic targets less than 2 mm in length，which needs further optimization.
Key Words:capacitive sensor；photoelectric sensor；dual sensor；yarn defect grading；yarn defect detection
