By taking a direct current on - line insulation monitor as an object the working principles and its structure of double - machine fault - tolerant system , in which 89c52 single chip computer is used as main machine is analyzed 摘要以直流系统线在线绝缘监测仪为对象,分析了以89c52单片机为主机构成的双机容错系统的结构及工作原理。
Demodulation analysis is widely used for diagnosing machine fault diagnosis . extracting information from modulation signal is an effective method to diagnose damaging faults fixed with gears and bearings 解调分析技术在具有齿轮、滚动轴承等零件的机械设备故障诊断中具有非常广泛的应用,已成为故障振动信号分析的最有效手段之一。
The intelligent diagnosis system of mechanical equipment fault has four subsystems including rotating machine fault diagnosis system , motor fault diagnosis system , bearing fault diagnosis system and reciprocating machine fault diagnosis system 机械设备故障智能诊断系统包括:旋转类转子故障诊断系统、电动机故障诊断系统、轴承故障诊断系统和往复机械故障诊断系统四个子系统模块。
In the rotating machine fault diagnosis system , the intelligent fault diagnosis methods based on knowledge and based on neural networks are available , and they are independent , also interactive . the diagnosis system is a visual system , has visual interfaces 旋转类转子故障诊断系统以转子系统为研究对象,分别利用基于知识的专家系统和基于神经网络的智能诊断技术建立了具有可视化界面的诊断系统。
In this paper , the average square root of the signal ' s first three imfs is used to diagnosis the machine fault . use this standard can improve the precision of the fault diagnosis , and reduce the false diagnosis in contrast to using the signal ' s correlative dimension 本论文将信号emd分解后其前三个imf分量的关联维数的均方根值用于机械故障的区分和诊断,与直接用原信号的关联维数作判断标准相比,可以明显提高诊断的精度,减少误判。
