Abstract
저압AMI시스템 구축을 위해 전자식 전력량계로부터 검침서버까지의 데이터 전송은 모뎀과 데이터집중장치(DCU)를 거쳐 전송하게 된다. 이때 모뎀과 DCU 사이의 네트워크를 전력선 통신(PLC)으로 구성하게 된다. 이 전력선 통신 기반의 원격 검침은 지중구간처럼 다양한 종류의 잡음 및 제한된 전송능력으로 인해 통신이 가능한 거리와 속도에 대한 제약이 따른다. 또한 PLC모뎀들을 등록하며 최적의 경로를 결정하고 통신할 수 있도록 해주는 S/W가 DCU에 탑재돼 있는 망 관리 에이전트이다. 전력선 통신에서는 이러한 망 관리 에이전트가 중요한 역할을 수행한다.
AMI시스템을 구축하는데 있어서 전력선 통신이 불가능한 곳에서는 무선처럼 다양한 통신방식을 혼합해서 구축하는 방식을 사용할수 있다. 그리고 IoT(Internet Of Things) 시대에서 무수히 많은 말단 장비들까지도 관리의 필요성이 대두되고, 단말까지의 경로가 TCP/IP망이 아닌 이기종 망이 복합적으로 연결되어서 서버에서 말단 장비까지 직접 접속이 불가능한 경우가 발생하기도 한다.
이에 본 논문에서는 망 관리 에이전트를 이중구조로 구축하여 상위는 서버와 통신을 하고 아래로는 또 다른 단말관리 에이전트와 통신하여 말단 장비들의 정보를 취득하고 제어할 수 있도록 제공하기 위해 JAVA 기반의 망 관리 에이전트 시스템을 구현하고, 실험 및 실증을 통해서 에이전트의 효과를 기대할 수 있다.
In order to construct a AMI system, data transfer from the electronic watt meter to the meter reading server is transmitted via the modem and the data concentration unit (DCU). At this time, the network between the modem and the DCU is configured by power line communication (PLC). Remote meter reading on the power line communication base has restrictions on the distance and speed with which various kinds of noise and limited transmission capability can communicate like the underground section. Also, software that registers a PLC modem, decides an optimal route, and enables communication is a network management agent installed in the DCU. In power line communication, such a network management agent plays an important role.
Where power line communication is impossible in constructing the AMI system, it is possible to use a method of building a mixture of various communication methods like wireless communication. From the era of IoT (Internet Of Things) to the countless end devices, the necessity of management also emerges and the path to the terminal is not a TCP / IP network but a heterogeneous network is connected in a complex manner and a server May be impossible to directly connect to the terminal equipment.
In this paper, we construct a network management agent in a dual structure, the parent communicates with the server, communicates with the management agent of another terminal, acquires the information of the terminal device In order to provide control so that we can implement JAVA based network management agent system, we can expect agent effect through experiment and demonstration.
