基于ARM的电机动态参数检测与处理系统设计

摘要

Motor run - time will produce a variety of electromagnetic and common mode interference effects to obtain accurate motor parameters. The electrical parameters of the traditional detection methods can not adequately filter out the scene of a variety of ：interference signals, thereby increasing the measurement error affect the accuracy of measurement parameters. this paper a practical design of interference suppression techniques greatly enhanced the accuracy and precision of measured parameters. The final.adoption of GSM / GPRS wireless network digital transmission, the next crew of the motor parameters collected sent to the host computer center expert diagnostic end systems for online real - time fault diagnosis and exclusion.%电机运行时会产生各种电磁和共模干扰，影响电机参数的准确获取。传统的电机参数检测方法不能充分滤除现场出现的各种干扰信号，从而增大测量误差，影响测量参数的准确性。为此，本文设计了一种实用的干扰抑制技术，大大提高了测量参数的准确性和精确性。最后通过GSM／GPRS无线网络数字传输技术，将下位机采集到的电机参数发送给上位机中心专家诊断端系统，进行在线实时故障诊断和排除。
