Research of computer jacquard circular knitting machine rotation position detection

通过研究经纬纺织机械股份有限公司的电脑提花圆纬机,根据圆纬机机械传动结构的传动比,计算出了圆纬机位置与编码器输出之间的关系式,分析比较了编码器脉冲圆整算法和误差消除算法造成的采集系统误差,利用可编程逻辑芯片设计了电脑提花圆纬机旋转增量式编码器的硬件采集电路,并通过对编码器输出的相脉冲进行倍频的抗干扰处理,保证了圆纬机位置的脉冲采集准确性,最后利用专用的可编程芯片设计软件模拟,对增量式旋转编码器实现方法进行了功能仿真和验证。

This paper researches computer jacquard circular knitting machine,which is made by Jingwei Textile Machinery Co.,Ltd.According to the ratio of transmission in the jacquard knitting machine mechanical transmission structure,the relationship between machine rotation position and encoder is calculated.It a analyzed the system error caused by the integer algorithm and the error elimination algorithm,used complex programmable logic device designs encoder acquiring circuit.To assure the acquiring data accurate,the anti-jamming methods and frequency multiplication methods are used.Software simulation is used to prove and verify the acquiring methods correct.
