【摘要】 介绍了一种测量时间动态调节的 M/ T测速法。此法通过动态调节测量时间 ,在硬件电路相同的条件下 ,可实现更宽转速范围的准确测量。还给出了参数设计、误差分析及软硬件实现框图。测量法已成功应用于转速范围为 0 .0 0 1～ 40 0°/ s的速度测量系统中。更多还原

【Abstract】 This paper introduces a M/T speed measuring method of auto-changing of measuring time, which, on condition of the same hardware, can realize accurate measurement of much wider speed by auto-changing of measuring time. Besides, it gives parameter designs, error analyses and diagrams on software and hardware. The method has been applied successfully into a speed measuring system, which has a speed range of 0.001～400 degrees per second.更多还原
