采用嵌入式处理器与可编程逻辑阵列的分布式圆机控制系统设计

为提高国产高档针织圆机的控制技术,针对现有圆机控制系统因采用集中式控制方式而存在系统扩展性较差,稳定性不够,控制对象复杂多样等问题,采用集中管理分散控制的分布式层次化结构体系,运用嵌入式控制技术,使用模块化电路设计方法,开发了一种基于嵌入式处理器STM32与可编程逻辑阵列(FPGA)的分布式圆机控制系统。实际应用表明,该系统不仅实现了圆机控制系统的所有功能,而且具有系统稳定性高,可扩展性好,控制容易等特点,从而极大地提高了控制系统的实时性。

Design of distributed control system of circular knitting machine based on STM32 and FPGA

To improve the control technique of the domestic high-grade circular knitting machine, and to solve the problems of low scalability, poor stability and complex and diverse control objects due to employing centralized control manner of the existing circular machine control systems, a new type of circular knitting machine control system using distributed control technipue is designed in this paper. A layered distributed architecture with centralized management and distributed control is adopted, and the embedded control technology accompany with the modular circuit design method is used based on the ARM processor STM32 and the field programmable gate array (FPGA). From the practical application, it is shown that this type of control system not only realized all the functions of the circular kniting machine control system, but also has the features of higher running stability and reliability and much better flexibility and is easier to control, thus greatly improved the real-time characteristic of the control system.
