摘　　要：针对现有提花圆纬机选针器工作速度慢、个体性能差异大、容易发热等问题,研究了一种基于快速正反充/消磁原理的新型电子选针器。根据磁材料磁化原理和选针器电磁线圈工作特性,进行选针器驱动电路设计,提出一种通过改变半硬磁材料磁力方向来改变并保持刀头状态的选针器控制方法。并基于此类选针器控制需求,针对单向并行总线结构存在信号串扰,抗干扰性能差等缺陷,提出了环状双向工业串行总线结构的提花控制系统设计方案。实验结果和现场试用情况表明,磁保持电子选针器工作温升在9℃以内,最高工作频率可达65 Hz,串行总线抗干扰性能良好,提花控制系统工作可靠。Aiming at problems of existing needle selectors in jacquard circular knitting machine,such as slow operation speed,large unit to unit performance variation and easy overheating,a novel electronic needle selector employing fast forward and reverse gaussing/degaussing of solenoid actuator was presented.Based on the magnetization of the ferromagnetic material and the operating characteristics of selector solenoid,a new circuit drive and a control method of needle selector were proposed to switch and to maintain the states of the selector blade by alternating the magnetization direction of the semi-hard ferromagnetic material of the solenoid core.To meet the requirements of such needle selectors,a design of jacquard control system for circular bi-directional industrial serial bus architecture was also proposed for minimizing signal crosstalk and enhancing anti-interference performance in unidirectional parallel bus architecture.The resnlts show both the laboratory experiment and field testing demonstrate that the new system design can sustain temperature rise within 9℃during operation.The maximum operating frequency of 65 Hz is obtained.Also the design enhances the serial bus′s anti-jamming performance and improves the jacquard control system reliability.
