Abstract

The distributing board in directly installed on the ground or the bottom surface of the building, and when vibrations such as earthquakes or external shocks occur, the possibility of damage or malfunction of electric components such as internal power devices, wiring, and protection relays increases. Recently, the need for a seismic type distributing board is increasing, and research and development of a distributing board having a vibration damping function and product launch are being conducted. In this paper, an IoT-based data collection device system capable of measuring vibration and environmental data of distributing board was designed and implemented. When vibration occurred on the distributing board, data was stored and visualized in the MySQL DB through Node-RED for monitoring and data storage using the MQTT protocol for reliable messaging transmission. The test was conducted by attaching the IoT device of the distributing board, and data was collected in real-time and monitored through Node-RED.

수배전반의 경우 지면 또는 건물의 바닥 면에 바로 설치되며 지진과 같은 진동이나 외부 충격 발생 시 수배전반의 내부 전력기기, 배선 그리고 보호계전기 등의 전기부품 손상, 오동작 발생 가능성이 커지게 된다. 이러한 이유로 최근 내진형 수배전반의 필요성이 대두되고 있으며, 제진기능을 갖는 수배전반의 연구 개발 및 제품 출시가 이루어지고 있다. 본 논문에서는 제진형 배전반의 진동, 온도, 습도 등을 측정할 수 있는 제진형 배전반의 진동 및 환경 데이터수집을 위한 IoT 시스템을 구현하였다. 제진형 배전반에 진동이 발생하였을 때 진동 정도 및 온습도 데이터를 측정하고 신뢰성 있는 메시징 전송을 위한 MQTT 프로토콜을 사용하였고, 모니터링과 데이터 저장은 Node-RED를 통해 MySQL DB에 데이터를 저장하고, 시각화를 진행하였다. 제진형 배전반에 IoT 기기를 부착하여 테스트를 진행 하였으며, 데이터를 실시간으로 수집하고 Node-RED의 대시보드 UI에서 진동 및 환경 데이터의 변화를 모니터링 하였다.
