激光-单板机纱线检测系统

A Yarn Testing System of Laser and Single Board Computer

本文叙述用He-Ne激光器和Z80单板机配以放大、滤波电路组成的纱线检测系统,对多种纱线进行谱分析,测定了CV%值。与Uster条干均匀度仪的测定结果对比表明:本系统准确、可靠,并具有体积小、成本低、灵活等特点,对实现纱线检测仪器的小型化、智能化具有重要意义。

In this paper, a yarn-testing system consisting of a He-Ne Laser and a Z80 Single Board Computer is described. By means of this system, frequency and wave length spectra, unevenness signal diagrams and CV% values for some kinds of yarns were produced. The test results were compared with those tested on Uster Tester with the same samples. And the agreement is quite good.
