Abstract

Recently, various technologies related to IIoT are introduced continuously due to the spread of IoT and smart factory industries. This paper proposes the construction of a two-way wireless network system for monitoring plant equipment using these various technologies. The main technologies used in this thesis are design techniques for micro sensor nodes to monitor facility conditions at various sites, MQTT technology for wireless communication between local server and sensor nodes and Node-RED based design technologies, which store data collected and can be easily presented to users via wired and wireless wires. In addition, a wireless two-way camera system was also implemented in which the screen images of the site can be viewed in the situation room according to the instructions of the situation room when determining abnormal conditions.

근래에는 IoT 및 스마트팩토리 산업분야의 확산으로 인하여 IIoT와 관련한 다양한 기술들이 지속적으로 소개되고 있다. 본 논문에서는 이러한 다양한 기술들을 이용한 공장 설비 감시용 양방향 무선 네트워크 시스템의 구축을 제안한다. 본 논문에서 사용되는 주요 기술들은 다양한 현장의 설비상태를 모니터링하기 위한 초소형 센서 노드의 설계기술, 개별 센서 노드에서 처리된 다양한 정보를 무선 시스템을 이용해 서버로 전송하고 또한 서버에서 새롭게 설정된 각종 센서의 임계치들을 개별 센서 노드로 무선 전송하기 위한 Wi-Fi 기반의 MQTT 기술, 수집된 데이터를 저장하고 유무선으로 사용자에게 손쉽게 표시할 수 있는 Node-RED 기반의 설계 기술 등이다. 아울러 개별 센서 노드에서의 이상상태의 판단시에 이를 상황실로 알리고 상황실의 무선조정에 의해 현장의 화면영상을 상황실에서 확인할 수 있는 무선 양방향 카메라 시스템도 함께 구현하였다.
