风机在线监测与诊断的应用设计

Application Design of Fan Online Monitoring and Diagnosis

摘要: 通过振动传感器对设备的运行状况进行在线监测，实时收集设备正常运行的振动值。振动值与旋转类振动信号采集标准对比，判断设备此时的运行状况。利用加速度传感器采集的时域波形，在系统上位机进行傅里叶变化转换成频域波形，结合机械故障的时频域基础理论判断设备的故障原因和故障部位。为旋转机械设备运行提供可靠的维修和运行建议。

Abstract: Fans use vibration sensors to monitor the operating status of the equipment online, and collect the vibration values of the equipment during normal operation in real time. The vibration value is compared with the rotation vibration signal collection standard to determine the operating status of the equipment at this time. The equipment collects the vibration signal using the time-domain waveform collected by the acceleration sensor, and converts the Fourier change into the frequency-domain waveform on the system host computer, and combines the basic theory of the mechanical fault in the time-frequency domain to determine the cause and location of the equipment failure. Provide reliable maintenance and operation suggestions for the operation of rotating machinery and equipment.
