摘　　要：提出了一种以32位ARM系列微控制器LPC2124为主控核心的感性绕组直流电阻测量方案,围绕如何提高测量精度和缩短过渡过程时间,介绍了测量系统的软硬件设计.通过助磁、同步采样、高压充电低压测量、程控放电法来实现感性绕阻直流电阻测试的方法和原理,可显著地缩短充放电的时间,提高测量精度.A 32 bit ARM series micro-controller LPC2124 master core perceptual winding was presented for straight resistance measurement. Focusing on how to improve the measurement precision and shorten the transition process of time, hardware and software designs of the measurement system were introduced. With magnetic assist, synchronous sampling, high-pressure charging low voltage measurement, program-controlled discharge method to achieve the perceptual around DC-resistance, it can significantly shorten the charging and discharging time and improve the measuring accuracy.
