A non-contact method and system for measuring spinning yam tension is developed using an image processing technique and based on the theory of yam balloon dynamics. The theoretical basis of the measurement is the relationship among yam tension, balloon shape, and spinning parameters. The yam tension is determined according to the geometric parameters of the balloon, which are measured from an image of the balloon. The digital image is captured with a CCD sensor, and processed in a computer using a wavelet transform technique. A measuring system is developed, and experiments are carried out. The results show that the proposed non-contact method is effective in the on-line measurement of spinning yam tension for improving the degree of automation of the spinning machine. 相似文献
