The Research and Design of Vibration Monitor

The principle and the framework of a real time monitor for rotating machinery equipments'absolute vibration intensity are described.The circuit structure of active integrator circuit for processing the sensor signals,band-pass filter circuit and MCU control circuit are detailed,the work mechanism and implementation mode thus magnetic-electric sensor signal processing circuit are expatiated,a new method which resolve the MCU sampling analog signal via ADC,the design of the band pass filter circuit effectively filter out the noise from the sensor output signal.Based on this ideal,the software of vibration monitor has been designed.This system has been tested faithfully in out laboratory,then the measure results are enumerated and the measuring error are analyzed.The measuring precision of ultrasonic distance measure vibration monitoring system is indicated higher by this experiment.
