오픈소스 기반 MQTT 프로토콜을 이용한 스마트 미터 실시간 데이터 수집 및 관리

Abstract

Currently, the rapid development of IoT technology has brought innovative changes to all industries and can have a significant impact on the smart grid AMI system. In fact, a smart meter, a key component within the AMI system, is a digital device that monitors energy consumption in real time and collects data. Through this, it improves energy efficiency and provides efficient energy management measures by analyzing consumers' energy use patterns. However, in the future, when hundreds of thousands of smart meters are installed on a large scale based on telecommunications carriers' IoT infrastructure, it is essential to quickly and reliably transmit and manage massive amounts of data. In order to transmit data efficiently in such AMI systems, MQTT IoT protocol may be used. The MQTT IoT protocol can be used to transmit data efficiently in AMI. MQTT is a lightweight publish-subscribe network protocol that transfers messages between devices with minimal bandwidth and power requirements and is suitable for the large amounts of small data packets typically generated by smart meters, so it can be used to transmit real-time meter reading data. Therefore, in this study, we designed and implemented a prototype smart meter real-time data collection and management system using the MQTT protocol based on various big data open sources under the assumption that the IoT infrastructure of telecommunication operators will be utilized in the future.
