摘　　要：提出利用永磁同步电动机伺服系统取代异步电机和机械凸轮,实现细纱机的数字卷绕方案。伺服驱动器中的数字信号处理器完成永磁电机的磁场定向控制和卷绕算法,工艺参数由PLC和DSP通过串行通信接口(SCI)进行通信。对DSP与PLC之间的通信协议、信号隔离和电平转换,给出了详细介绍。现场运行表明该软、硬件设计方案是可行的,并具有通用性。Put forward permanent magnetic synchronous servo system replaces induction motor and mechanical cam so as to realize digital winding in ring spinning machine. DSP in the servo driver is responsible for the field-orientated control and winding formation algorithm. Technological parameters are transferred by SCI between PLC and DSP. This paper describe the interfaces between DSP and PLC such as signal isolation, level conversion and communication protocol. The worksite operation demonstrates the software and hardware schemes are feasible and general.
