纱线速度的非接触式测量方法的研究

Study on Non-contact Measurement of the Speed of Yarn

指出接触式测量纱线速度的不足之处，提出了基于数字信号处理技术的非接触测试该指标的方法，实验结果表明此方法是可行的。

The drawback of measuring the speed of yarn by the contact method is described, and non-contact measuretnent based on the technology of DSP is put forward, which is proved feasible by experiment.
