摘　　要：针对国内喷气织机在幅宽和入纬率等性能上的不足,设计开发了一套基于ARM+FPGA的高速喷气织机控制系统,使用FMC(可变存储控制器)并行总线完成两者间数据的传输。根据喷气织机控制系统的功能,利用模块化思想,将整个硬件控制系统分为主控子系统、引纬控制子系统、离合与制动子系统、输入与输出子系统、人机交互子系统和电源子系统,并分别对各子系统进行了设计和制作。根据喷气织机引纬运动时序织造工艺,设计了以引纬控制寄存器和内部存储模块为核心的FPGA内部硬件电路。基于FreeRTOS实时操作系统,利用Mealy型有限状态机模型,结合主轴时序控制策略,完成了高速织造软件框架设计。最后,在搭建的硬件控制系统模拟试验平台上,对该系统进行测试。结果表明,该控制系统具有稳定性强、运行速度快、抗干扰能力强的特点,能够满足喷气织机公称筘幅540 cm的高速生产需求。Aiming at shortcomings of domestic air-jet looms in terms of width and weft insertion rate,a highspeed air-jet loom control system based on ARM+FPGA was designed and developed.The FMC(Flexible Memory Controller)parallel bus was used to complete the data transmission between the two.According to the function of air-jet loom control system,the whole hardware control system was divided into main control subsystem,weft insertion control subsystem,clutch and brake subsystem,input and output subsystem,human-computer interaction subsystem and power supply subsystem by using the modular idea.According to the timing weaving process of air-jet loom weft insertion movement,FPGA internal hardware circuit with weft insertion control register and internal storage module as the core was designed.Based on FreeRTOS real-time operating system,high-speed weaving software framework was designed by using the Mealy finite state machine model and the spindle timing control strategy.Finally,the system was tested on the hardware control system simulation experimental platform.The results showed that the control system had the characteristics of stronger stability,faster running speed and stronger anti-interference ability,which can meet high-speed production demand of 540 cm nominal reed width of air-jet loom.
