目的 为进一步提高筒子纱包装过程的自动化程度，采用分布控制和集中管理模式设计一种筒子纱包装生产线控制系统。方法 该控制系统主要包括上位机、自动包装模块、自动码垛模块。控制系统硬件可分为监控层、应用层、控制层和设备层。上位机基于TCP/IP协议制定系统应用层，通过工业以太网与各模块控制器通讯。各模块控制器会将传感器采集到的信息发送至上位机，上位机进行数据处理、分析、存储等操作，进而实现数据共享。针对筒子纱翻转系统，利用机器视觉采集筒子纱侧面图像，经图像处理后，与模板进行比较，进而判断筒子纱姿态并执行翻转操作，最后进行实验研究。结果 实验结果表明，所述控制系统的包装成功率可以达到99.7%以上。结论 筒子纱自动包装生产线具有成功率高、包装速度快、稳定性高等优点，可满足筒子纱包装需求。

In order to improve the automation of cheese yarn packaging process, a control system for cheese yarn packaging production line is designed by means of distributed control and centralized management. The control system mainly includes upper computer, automatic packaging module and automatic stacking module. The hardware of control system can be divided into monitoring layer, application layer, control layer and equipment layer. The upper computer makes the system application layer based on TCP/IP protocol and communicates with each module controller through industrial Ethernet. Each module controller will send the information collected by the sensor to the upper computer, and the upper computer will carry out data processing, analysis, storage and other operations, so as to realize data sharing. For the cheese yarn flipping system, the side image of cheese yarn is collected by machine vision. After image processing, the attitude of cheese yarn is determined by comparison with the template and the operation of cheese yarn flipping is performed. Finally, an experimental study is carried out. The experimental results show that the packaging success rate of the control system can reach more than 99.7%. The automatic package production line of cheese yarn has the advantages of high success rate, fast packaging speed and high stability, which can meet the packaging requirements of cheese yarn.
