摘要
无缝内衣机作为一种典型的圆型纬编针织机械设备,专门用于生产无缝针织服装。目前高档无缝针织设备主要依赖进口,国内无缝内衣机起步较晚,电脑控制系统在功能、可靠性及稳定性等方面有待提升。通过对无缝内衣机机械结构、编织工艺及控制需求进行分析,提出无缝内衣机控制系统人机交互层、实时控制层和驱动层的三层结构总体设计方案,阐述了控制系统硬件、软件的设计思路。实时控制层通过FPGA芯片内部逻辑电路搭建双口RAM的架构实现人机交互层与实时控制层的数据传输。通过对控制系统整体功能的测试分析,验证了系统设计方案的可行性。测试结果表明,控制系统整体运行可靠、实时性好。
As a typical circular weft knitting machine, seamless underwear machine was designed to produce seamless knitwear. Currently, high-grade seamless knitting equipment is mainly imported. Domestic research of seamless knitting technology started late. The computer control system remains improving in terms of function and reliability. Through the analysis of mechanical structure, knitting technology and control requirements of seamless underwear machine, this paper puts forward a design scheme for three-layer structure of seamless underwear machine, i.e. human-computer interaction layer, real-time control layer and driving layer. Besides, the design thought of hardware and software of control system is described. The real-time control layer achieves data transmission between the human- computer interaction layer and the real-time control layer through dual-port RAM circuit which is built by internal logic circuit of FPGA chip. The test and analysis of overall functions of control system verify the feasibility of this deisgn scheme. The test result indicates that the overall control system is reliable and real-time.
