회전체 진동 데이터의 AC/DC 성분 데이터 획득 및 분석 장치 = An Acquisition and Analysis Equipment of Dynamic/Static Data on a Rotating Vibration

다국어 초록 (Multilingual Abstract)

This paper is proposed that in-output Digital module is acquired a vibration signal of
a rotating machinery by Data Acquisition System. The module is designed to get ride of
nose through low pass filter on the vibration signal from sensors and set the gain value
for being able to sampling AC to DC, and also the sampled data by sampler and the
conversed data by DIP/FPGA is supplied to the analyzer for analysis at a software tool.
The DIP(Digital Signal Processor) of the Digital input/output Board makes Average
voltage, Peak to Peak voltage, RMS(Root Mean Square) and Gap voltage, also FFT(Fast
Fourier Transform) for rotating vibration diagnosis.
