Abstract
TETRA(TErrestrial Trunked RAdio) is wireless communication system generally adopted to public network and backbone network, as the technology of Trunked Radio System specified by ETSI(European Telecommunications Standards Institute) and currently adopted to the Electric Power IT Backbone Network in Korea. DLMS(Device Language Message Specification) is used in order to meter an electric measuring instrument value. In this paper, DLMS Server and Client simulator are used based on Window operating system. The multi-functional gateway, which transforms the communications based on RS-232C between DLMS Server Simulator and Client Simulator to the one based on TETRA PEI(Peripheral Equipment Interface), is developed such that DLMS SCADA(Supervisory Control And Data Acquisition) system is constructed based on TETRA.
TETRA(TErrestrial Trunked RAdio)는 국내 전력 IT 무선 기간망에 적용된 ETSI(European Telecommunication Standard Institute)가 정한 디지털 주파수공용통신(TRS, Trunked Radio System) 기술로서 공중망 및 기간망에 적용되고 있는 무선통신시스템이다. DLMS(Device Language Message Specification)는 전기 계량기 값을 검침하기 위해 쓰인다. 본 논문에서는 윈도우 기반의 DLMS Server와 Client Simulator를 사용하였다. 또한 DLMS Server Simulator와 Client Simulator 간의 RS-232C 기반의 통신을 TETRA PEI 기반의 통신으로 변환하는 다기능 게이트웨이를 개발하여 TETRA 기반 DLMS 원방 감시 시스템을 구축하였다.
