光纤环绕制中张力控制与高精度排线的研究

针对光纤环各类绕制方式对温度变化抑制能力的研究,得到四级对称绕制设备的具体要求。目前的光纤环绕制设备与其进行比较后,发现主要有以下缺陷:绕制过程中张力控制波动大、排线精度比较低和绕制设备的自动化程度不完全。对光纤环绕制设备的进行改进:首先,建立供纤轮与绕纤轮之间速度差的数学模型;并经过仿真得到换光纤层绕制时必须改变供线轮的转速以保证张力的基本范围;而且使用舞蹈轮微控设备实现张力波动小范围控制。其次,采用光纤绕制检测设备实时检测光纤排线性能;并确定合适的滞后角度以实现高精度排线。最后,采用一从两主的电机控制方法实现光纤绕制设备的自动绕制。经过实验验证:该张力控制方法可以实现不同层光纤张力的高精度控制,而采用该排线方式也可以完全实现高精度排线的自动化。

The Research of Tension Control and High Precision Winding in Optical Fiber Winding System

By studying the temperature changes suppression of different fiber loop winding way, we get the requirement of realizing the four symmetrical winding. However, comparing the fiber ring winding equipment, we find the following shortcomings: wide fluctuations of winding tension, low precision winding and incomplete automation winding equipment. In this paper, we research the winding equipment: firstly, we establish a mathematical model of the winding equipment based on the difference speed between the winding wheel and fiber wheel, then, we can realize small-scale fluctuations tension changes when changing layer and winding the fiber ring using dance round microcontroller devices; secondly, the system can observe optical fiber ring performance by using the optical fiber winding real-time testing equipment, and determine the appropriate lag angle in order to achieve high accuracy optical fiber ring; finally, we get a way to achieve a reasonable control mode of fiber winding device by controlling one main electric motor and two minor ones. Through experimental verification: The tension control method can achieve high-precision fiber tension control even between the different layers, and the use of the reasonable control mode can be fully automated precision winding.
