Abstract

In this paper, oneM2M based data monitoring and acquisition system is designed and implemented to measure and transmit the voltage, current, temperature, acceleration and vibration of the motor. The proposed system can detect electrical faults (overcurrent, reverse phase, phase loss, ground fault) and mechanical faults (MC counter, motor operation time, bearing and winding temperature, motor speed, insulation resistance). The system consists of sensor data collection, web server, php, database, wired/wireless communication system. The insulation resistance and the motor speed were measured, and the experimental results were similar for both the test resistance value and the reference input value.

본 논문에서는 회전기기의 전압, 전류, 온도, 가속도, 진동 등을 측정 전송할 수 있는 oneM2M 기반의 실시간 회전기기 센싱 데이터 수집 및 모니터링 시스템을 설계하고 구현하였다. 구현된 시스템은 전기적 결함(과전류, 역상, 결상, 지락)과 기계적 결함(MC 카운터, 모터동작시간, 베어링 및 권선온도, 모터 회전수, 절연저항)의 전기 또는 물리적인 현상 측정이 가능하며, 센서데이터 수집, 웹서버, php, 데이터베이스에 데이터 저장, 웹 접속 통한 데이터 모니터링까지 가능하도록 시스템을 구성하였다. 회전기기에서의 기계적 결함을 실험한 결과, 절연저항 및 모터회전수 측정 결과 시험저항 값과 기준 입력값 각각에서 유사한 실험 결과를 보였다.
