摘　　要：为解决电磁噪声对工业缝纫机面线张力控制系统的影响,在分析电磁噪声特点的基础上,提出一种通过避开主噪声持续A/D采样的降噪方法,并详细讨论该方法的原理和在FPGA上的硬件实现。实验表明,该方法能有效地解决电磁噪声引起的缝制出的图案不规整,容易断线等问题,是一种有效和实用的方法。In order to solve the influence of the electromagnetic noise in industrial sewing machine tension control system, A method is proposed to reduce the noise through to avoid the main noise to A / D sample sustained on the basis of the characteristics of electromagnetic noise, And discussed the principles of the method in detail and hardware implementation on the FPGA. Experiments show that it can effectively solve that the sewing patterns are not regular and easy off-line issues and so on caused by the electromagnetic noise It is an effective and practical method.
