摘　　要：为确保圆纬机在高速运行时工作稳定,针对传统上位机软件界面控制功能单一、人性化程度低、整体水平不高的问题,提出一种基于Linux操作系统的圆纬机人机交互系统设计方法。基于ARM微处理器及扩展电路的硬件平台,软件编程采用Qt开发工具,采用多线程方式定制人机交互系统操作界面。软件通过采集花型文件数据,结合圆纬机工作流程,解析出选针器控制参数,参数经总线传递给下位机FPGA,下位机根据参数指令结合同步控制器信号实现对选针器的控制。功能测试结果表明,该控制系统功能齐全、界面友好、操作方便、实时性强,动态响应时间小于2.8 ms,具有较好的人机交互能力。In order to ensure the stability of circular weft knitting machine when it runs at high speed,a design method of man-computer interaction system based on Linux operating system is proposed to solve the problems of single control function,low humanization and low overall level of traditional upper computer software interface.Based on the hardware platform of ARM microprocessor and expander circuit,Qt tool is used for software programming,and multi-thread mode is used to customize the man-computer interaction system.The software analyzes the control parameters of the needle selector by collecting the pattern file data.The parameters are transmitted to the lower computer FPGA through the bus.The lower computer controls the needle selector according to the parameter command and the synchronous controller signal.The function running test shows that the control system has complete functions,friendly interface,convenient operation,strong real-time effect,dynamic response time less than 2.8 ms,and good man-computer interaction ability.
