摘　　要：电脑横机选针器精准实时的控制是实现稳定、可靠编织的关键,国产系统一般基于单核控制方式采用8段式选针器。文中针对传统方式提出一种基于ARM和FPGA双控核心的5段式选针器控制方案,ARM模块完成对花样文件的数据解析并发送给FPGA, FPGA接口控制采用VHDL编程实现,选针器数据缓存采用双缓冲结构,设计了能够实现实时控制的流水线执行结构。结果表明,优化后的方案兼容性好,升级方便,可以实现5段式稳定控制,有效提高了系统的整体性能,具有较高的应用价值。Accurate and real-time control of needle selector for computerized flat knitting machine is the key to realize stable and reliable knitting. Generally, 8-segment needle selector is adopted in domestic system based on single core control mode. In view of the traditional way, 5-segment needle selector control scheme based on arm and FPGA is proposed. ARM completes the data analysis of pattern file and sends it to FPGA. FPGA control adopts VHDL programming, needle selector adopts double buffer structure, and completes the design of pipeline execution structure. The application results show that the optimized scheme has good compatibility, which effectively improves the overall performance of the system with high application value.
