Abstract

The invention relates to a method and a device for detecting a yarn state in a carbon fiber weaving process. The method comprises the following steps: acquiring an original image of a weaving spindle on carbon fiber weaving equipment; preprocessing the original image to obtain a preprocessed target image; recognizing whether the yarn is broken or not according to the target image, recognizing whether the yarn is wound or not according to the target image, and recognizing whether the yarn generates a fiber ring or not according to the target image; and obtaining the yarn state in the carbon fiber weaving process according to the recognition result. According to the method for detecting the yarn state in the carbon fiber weaving process, the related image of the weaving spindle is obtained, then the states of yarn breakage, yarn winding, fiber ring generation and the like are recognized on the basis of the image, the yarn state is effectively detected, the defect that detection is not accurate due to the fact that a sensor is adopted traditionally is overcome, and the blank in the prior art is filled.

Description

technical field [0001] The invention relates to the field of yarn state detection, in particular to a yarn state detection method and device in a carbon fiber weaving process. Background technique [0002] The current yarn detection in the weaving process is mainly divided into manual detection and non-manual detection. Most weaving enterprises use manual methods to detect the yarn breakage that occurs during the weaving process, but the two yarn states of yarn entanglement and fiber loops cannot be detected in time by manual work. In the non-manual detection, a sensor module is developed, which can detect whether the tension of the weaving yarn is abnormal, so as to minimize the occurrence of weaving defects. Due to the long-term use of the spindle, the elastic device at the bottom of the spindle will have no elasticity. In this case, the tension sensor cannot work, and therefore, existing sensors cannot detect states such as fiber winding on the yarn guide wheel. Conten...
