竹节纱工艺参数的自动识别

为提高竹节纱工艺参数的检测速度和检测精度，提出了利用计算机检测竹节纱的方法。阐述了竹节纱工艺参数检测的基本原理，并用自行研制的竹节纱检测系统测试了给定样纱，得到了竹节纱粗细信号的时间序列图，竹节长度、竹节间距序列图，竹节长度分布图，竹节间距分布图以及竹节倍率分布图，与竹节纱设置的初始工艺参数进行了对照，具有很好的一致性，并对产生的误差进行分析，从而证明了该系统的有效性，对指导实际生产具有重要意义。

Automatic identification for processing parameter of slub yarn

The purpose of this study is to improve the speed and precision of testing the processing parameters of slub yarn, and use of computer to carry out this testing is proposed. The basic principal of testing the processing parameter of slubby yarn was introduced. And we developed a slub yarn testing system which was used to test the sample of slub yarn. We got time sequence chart of thickness of slubby yarn, distance sequence chart of slub length and slub space, and distribution charts of slub length, slub space and slub scaling factor. The results tested showed in good agreement with the originally set parameters. The resulting errors were analyzed also. Experiments demonstrated that this testing system is effectively, and can be adopted in production.
