REMOTE METER SYSTEM BASED ON PRIME POWER LINE COMMUNICATION AND SLAVE PLC MODEM REGISTRATION METHOD USING SAME

摘要

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.;COPYRIGHT KIPO 2016
