초록

Advanced Metering Infrastructure (AMI)와 Internet of Things (IoT)는 동일한 구성방식과 동작원리에도 불구하고, 현장 단말인 스마트미터와 센서에서 사용하는 객체 모델링과 통신 프로토콜 차이로 인하여 이질적인 시스템으로 인식되고 있다. 그러나 향후에는 IoT 기술 확장과 시장지배력 강화에 따른 상호 간 연계 및 연동은 불가피할 것으로 예상된다. 따라서 본 논문에서는 Device Language Message Specification(DLMS) 및 Lightweight Machine to Machine (LwM2M) 표준의 객체 모델링 방식과 자원관리 특징을 분석하여 상호 간 연동 모델을 제안한다. 제안하는 연동 모델은 DLMS와 LwM2M 간 1 대 1 변환 방식을 제공하며, LwM2M의 캡슐화(Encapsulation) 전송방식 대비 최대 46.5%로 패킷 크기를 감소시킬 수 있는 장점이 있다.

Despite the same system architecture and operation principle, Advanced Metering Infrastructure (AMI) and Internet of Things (IoT) are recognized as a heterogeneous system. This is due to the different object modeling and communication protocols used in smart meters and sensors. However, data interworking between AMI and IoT is expected to be inevitable in the future. In this paper, we propose Device Language Message Specification (DLMS) to Lightweight Machine to Machine (LwM2M) conversion model. The proposed interworking model can reduce the packet size by 46.5% compared to that of the encapsulation method.
