摘　　要：为解决钻机立轴转速的测量问题,提出了频率/电压转换方法。在分析LM2917频率/电压转换电路工作原理的基础上,设计出钻机立轴转速测量的基本电路。使用结果表明:该电路的精度和可靠性均能满足相关频率电压(F/V)的转换测试工作。In order to resolve the problems of measuring the rotational speed of vertical spindle for drillers, the frequency/voltage transformation method is proposed. The paper analyzes the operating principle of LM2917 frequency/voltage transformation circuit and designs the basic circuit to measure the rotational speed of vertical spindle for drillers. The practical application shows that the accuracy and reliability of the circuit can meet the needs of frequency/voltage transformation measuring work.
