摘　　要：针对现有变频器驱动卷绕摩擦辊、横动槽筒结构的不足,设计了以PLC、STC单片机为核心的主从控制结构,驱动高精度交流伺服、高速无刷直流电机,组成空气包覆纱机精密交叉卷绕控制系统。文中阐述了PLC控制系统框图,STC单片机卷绕-横动控制器硬件组成,恒线速度卷绕、伺服排线控制策略,设计了双锥形等卷绕比卷绕算法,最后给出了基于Modbus协议的主从通信及单片机控制流程。改进的卷绕系统能够可靠运行在卷取速度1000 r/min条件,且可以单锭独立设置纱筒成型参数,满足高速柔性化、精密卷绕的要求。Aiming at the disadvantages on winding friction roller,traverse groove drum independently driven by converters,a precision cross winding control system of air covering yarn machine was designed,which was based on the master-slave control structure of PLC、STC MCU.Then the high-precision AC servo motor and high-speed brushless DC motor were driven by them.The diagram of PLC control system were discussed in the paper,the hardware structure of winding-traverse controller based on STC MCU,constant linear velocity winding control algorithm,as the servo traversing control algorithm were described respectively,Also the double cone winding algorithm for uniform winding ratio was designed.Modbus serial communication protocol and winding-traverse control programming were given at last.The practical applied results shown that the improved system was provided with the advantage such as highspeed,flexibility,precision winding under the condition of 1000 m/min rewinding speed.Also the yarn forming parameters can be set independently in single-spindle.
