Abstract

The objective of this research is to improve the efficiency of data collection from many machine components on smart factory floors using IoT(Internet of things) techniques and cloud platform, and to make it easy to update outdated diagnostic schemes through online deployment methods from cloud resources. The short-term analysis is implemented by a micro-controller, and it includes machine-learning algorithms for inferring snapshot information of the machine components. For long-term analysis, time-series and high-dimension data are used for root cause analysis by combining a cloud platform and multivariate analysis techniques. The diagnostic results are visualized in a web-based display dashboard for an unconstrained user access. The implementation is demonstrated to identify its performance in data acquisition and analysis for rotating machinery.

스마트 팩토리 시대가 열리면서 발전 플랜트에서 발생하는 빅데이터를 활용한 설비 유지 보수 방법론이 부각되고 있다. 본 연구에서는 데이터 기반 방법론의 효과적인 적용과 발전 플랜트 실시간 성능 모니터링을 위해 사물인터넷 기반 클라우드 플랫폼을 제안한다. Short-term Analysis에서는 사물인터넷 센서를 이용하여 학습된 건전성 인자와 패턴 비교를 통해 설비의 상태 진단과 결과 전송을 목적으로 한다. Long-term Analysis는 취합된 고차원 데이터를 활용하여 설비간 관계 파악과 인과관계 확인을 통한 트렌드 분석을 목적으로 한다. 분석 및 진단 결과는 클라우드 플랫폼의 웹 기반 시스템을 통해 시각화하여 사용자의 접근성을 향상시켜 장소나 접속 기기에 상관없이 데이터를 확인할 수 있도록 한다. 개발된 플랫폼의 성능 검증은 회전기계류 테스트베드로 진행한다.
