摘　　要：根据正交光电编码器测速原理,在分析了M法测速的测量误差和分辨率的基础上,提出了一种改进的转速高精度测量方法——变M法,即同时测量正交的两组脉冲序列的上升沿和下降沿,极大的减小了转速和转角测量误差,提高了分辨率。还提供了一种适用于工业现场环境条件的,基于正交编码器测速算法的虚拟仪器软硬件设计方案及其实验效果。According to the principle of measuring velocity of Quadrature Encoder and in the analysis of measurement error and resolution based on M velocity method, this paper proposed a new way of an improved precision measurement method-Improved M velocity method, simultaneous measurement of orthogonal two groups of pulse sequences rising and falling edges. This article also provides virtual instrumentation software and hardware design and its experimental results based on a suitable industrial site environmental conditions and quadrature encoder speed algorithm.
