摘要：为实现一种新型高度自动化工业缝纫机电气控制系统的设计，重点阐述了工业缝纫机嵌入式控制器（模式盒）及步进电机控制驱动模块的研制，提出了在TMS320F2812数字信号处理器（DSP）、A3P060现场可编程门阵列（FPGA）硬件平台上搭建实时操作系统μC/OS-II的模式盒控制方案，并在分析步进电机动态特性的基础上，给出了步进电机升降速曲线实现方式，实现了高速状态下三轴电机联动及多种定制花样的精确缝制。实验结果证明，该系统具有动态响应良好，运行噪声低，整机功耗低等特点。

Abstract: For realizing the design of a new type of highly automated industrial sewing machine electrical control system, the industrial sewing machine embedded controller and the design of driving module controlled with step motor were described. The realtime operating system μC/OS-II was proposed to build on the hardware platform composed of TMSF320F2812 digital signal processor(DSP) and A3P060 fieldprogrammable gate array(FPGA) in the design of the embedded controller. The method for the speedup and speeddown curves was presented by analyzing the dynamic characteristics of the step motor.The threeaxis motor linkage and the accurate stitchwork of various graph customed in the high speed running state was achieved. The experimental results show that the lowpower machine has high dynamic peformance and work quietly.
Key words: industrial sewing machine; digital signal processor(DSP); μC/OS-II; step motor; TMS320F2812; fieldprogrammable gate array(FPGA)
