Abstract

In smart factories and industrial IoT, all facilities in a factory are monitored over the Internet, thereby facility can reduce the downtime and increase the availiability by preventive maintenance before it breaks down. The abnormal conditions of the major facilities in the plant are caused by abnormal temperature rise, vibration, and variations in noise. Consequently, it is critical to develop a very small smart device that is easily installed in a small space to enable real-time monitoring of the vibration status of the facility. In this study, smart devices were developed for smart factory fault prediction and robustness management using ultra small micro-controllers with WiFi capabilities and MEMS acceleration sensors.

스마트 팩토리나 산업용 IoT에서는 공장 내 모든 기기와 장비가 인터넷으로 연결되어 모니터링 됨으로써, 장비나 기기가 고장 나기 전에 예지보전을 통해 설비의 다운타임을 줄이고, 생산성과 가용성을 높일 수 있다. 공장내 주요 설비의 이상 상태는 온도의 이상 상승, 진동과 소음의 변화를 수반하여 나타나게 되므로, 좁은 공간에 쉽게 설치하여 설비의 진동상태를 실시간으로 모니터링 할 수 있는 초소형 스마트 디바이스 개발은 매우 중요하다. 본 연구에서는 WiFi 기능이 있는 초소형 마이크로컨트롤러와 MEMS 가속도 센서를 이용하여 스마트 펙토리의 이상 고장 예지 및 건전성 관리를 위한 스마트 디바이스를 개발하고 그 성능을 분석하였다.
