摘　　要：电脑横机导纱器的精确调度是实现复杂嵌花花型稳定编织的关键,国产系统一般最多可携带16把导纱器,较难完成复杂嵌花花型的编织。针对传统方式提出一种基于FPGA的导纱器控制方案,当上位机完成对花样文件数据解析后获取控制数据,利用PCI104总线发送给下位机FPGA,FPGA采用串行比较方式对比导纱器位置和当前机头位置数据后,实现32把导纱器的调度控制。结果表明,国产电脑横机采用该导纱器控制系统后有效提高了系统的整体性能,动态响应时间小于3.00 ms,实时性强、编织效果好,具有较高的市场应用价值。The reliable scheduling of yarn carriers on computerized flat knitting machine is the key to realize the stable knitting of complex intarsia pattern.Generally,the domestic system can carry up to 16 yarn feeders,so it is difficult to complete the knitting of complex intarsia pattern.In view of the traditional way,this paper puts forward a yarn carrier control scheme based on FPGA.The upper computer obtains the control data after analyzing the pattern data,and sends it to FPGA by PCI104 bus.After comparing the yarn carrier position and the head position data by serial comparison mode,the FPGA realizes the control of 32 yarn carriers.The test results show that the overall performance of the domestic computerized flat knitting machine is improved after adopting the yarn carrier control system,and dynamic response time is less than 3 ms,with strong real-time performance and good knitting effect,which has high market application value.
