梳棉棉网中棉结的在线视觉识别

针对国内棉纺织企业采用目光检测法检测半成品中棉结含量存在检测精度低、速度慢等问题,应用计算机视觉技术,设计棉结在线识别系统.采样得到的棉网图像,经图像预处理消除光照不匀和噪声等因素后,采用一维最大熵法结合初始分割阈值和面积阈值的方法来识别棉结,并将识别结果与人工目测结果进行对比.研究表明,本文的识别方法具有识别精度高、速度快、误检率和漏检率低等特点,符合在线检测连续性要求.     

Searching for Strange Attractor in Sliver Irregularity Series

The chaotic nonlinear time series method isapplied to analyze the sliver irregularity in textileprocessing. Because it unifies the system's determinacy andrandonmess, it seems more adaptive to describe the sliverirregularity than conventional methods. Firstly, the chaoscharacter, i. e. fractal dimension, positive Lyapunovexponent, and state space parameters, including time delayand reconstruction dimension, are calculated respectively.As a result, a positive Lyapunov exponent and a fractaldimension are obtained, which demonstrates that the systemis chaotic in fact. Secondly, both local linear forecast andglobal forecast models based on the reconstructed state areadopted to predict a segment part of the sliver irregularityseries, which proves the validity of this analysis.Therefore, the sliver irregularity series shows the evidenceof chaotic phenomena, and thus laying the theoreticalfoundation for analyzing and modeling the sliver irregularityseries by applying the chaos theory, and providing a newway to understand the complexity of the sliver irregularitymuch better.

梳棉试验机的打样试验与设备改造

探讨梳棉试验机在纺纱打样试验过程中存在的问题及解决方案.通过原棉及棉型化纤等原料的试纺试验,发现原棉经梳棉试验机梳理后棉网中杂质较多、原棉及棉型化纤输出的纤维网纵横向不均匀、卷网滚筒在生头卷绕纤维网时较难粘住等现象.经多次试验、分析研究,对该设备相关部件进行了更新改造,实际运转试验后发现,棉网均匀且含杂较少,纤维网生头也很容易,改善了纤维层的均匀度,为后道纺纱打样试验工序提供质量较高的半制品原料.
