Zusammenfassung: | According to the present invention, a remote meter system based on prime power line communications (PLC) includes: multiple low-pressure meter units including multiple low-pressure gauges installed on a reception side to execute power measurement operation and multiple slave PLC modems which are installed on each of the low-pressure meters and execute a communication operation through (R-phase, S-phase, T-phase, and N-phase) power lines connected to a transformer; and a data concentrator unit (DCU) which determines the allowed number of registered master PLC modems while taking a channel state into account when the master PLC modems transfer a registration request signal after installing the slave PLC modems, collects the measurement data transmitted by the low-pressure meter units after a registration operation, and transmits the collected measurement data.
본 발명의 프라임 전력선통신 기반의 원격검침 시스템은, 수용가 측에 설치되어 전력 검침을 수행하는 복수개의 저압계기들과, 상기 저압계기들 각각에 설치되며, 변압기와 연결된 4상(R상, S상, T상, N상)의 전력선을 통해 통신을 수행하는 복수개의 슬레이브 PLC 모뎀들을 구비하는 복수개의 저압검침부들; 및 상기 슬레이브 PLC 모뎀들이 설치된 후 등록요청 신호를 마스터 PLC 모뎀들로 전송한 경우 채널상태를 고려하여 상기 마스터 PLC 모뎀들의 등록 허용 수를 결정하고, 등록 후 상기 저압검침부들이 전송한 검침데이터 들을 수집하고, 전송하는 데이터집중장치(DCU)를 포함하는 기술을 제공함에 기술적 특징이 있다. |
