摘　　要：介绍了一种高压共轨电磁阀电感测量模块的设计。设计了利用定时器进行多周期采样高频正弦波的采样方法,可准确采集到正弦波的幅值及周期;再通过电压比例法计算出电磁阀的粗略电感值;最后通过直方图过滤的统计方法,得出电磁阀的测量电感值。实验结果表明,本设计性能稳定,测量精度高,满足应用要求。： This paper presents a design of inductance measurement model for high pressure common rail solenoid valve. A high frequent signal sampling method based on timer is introduced. It sample data in multiple cycles and can accurately samp｜e the amplitude and pe- riod of the signal. Using the method of voltage proportion computation a rough inductance of the solenoid valve is calculated. Then it uses the histogram to filter the data, and get the final inductance. Experimental results indicate that the performance is stable and the precision is high, the clesigh can meet the application requirement.
