摘　　要：传统的M/T测速方法在测量转速时,存在误差大的问题。采用AVR嵌入式ATmega128微机处理器作为控制核心,提出一种转速检测自动修正控制算法,此算法低速时也能完成0~±2000r/min的高精度实际转速测量。研制出集测量、转换、显示及反馈功能于一体转速测量装置,通用于交、直流电动机的转速测量中,具有检测时间短、测量精确度高、寿命长及通用性强等特点。When the conventional M/T speed measurement method is used to measure the rotation speed,there is a problem that the tolerance is large.Using AVR embedded ATmega128 microcomputer processor as the control core,an automatic correction control algorithm for rotation speed detection is proposed.When the speed is low,high-accuracy actual rotation speed measurement of 0 to±2000 rpm can also be achieved.A set of measurement,conversion,display and feedback functions in one speed measurement device is developed,which is commonly used in AC and DC motor speed measurement,with a short detection time,high measurement accuracy,long life and versatility.
