Realization of Communication and Sensor Signal Processing Technique for Condition Monitoring of Check Valve

Check Valve 상태감시를 위한 통신 및 센서신호처리 기능 구현

This paper presents a realization of sensor signal processing(noise filtering) and Fieldbus based communication for condition monitoring of check valve. we first acquired the AE(Acoustic Emission) sensor data at the KAERI check valve test loop, and their frequencies were analyzed to find the informative band. To reject background noises, bandpass filters have been designed. Also, to send the processed data to a remote site, wired communication facility has been realized via DeviceNet.
