摘要
介绍了一种宽范围转速测量的实现方法.其方法以S7-200PLC为核心,以增量光电编码器作为检测器件,采用变化闸门时间的频率法,实现高分辨率、宽范围转速在线连续测量.
A method of measuring wide-range rotation rate is introduced in this paper. In this method S7-200 PLC is used as the core and incremental photoelectric encoder as the detection component.By frequency method of varying gate time,the on-line measurement could not only be wide-ranging,but also with high-resolution.
