Power Line Carrier Communication Unit

The design and production of power line carrier communication unit conform to relative technical standards and specification (2013 version) of the power user electric energy data acquisition system of State Grid Corporation of China.

The power line carrier module of concentrator can be directly embedded in the low-voltage I type concentrator in line with the standard of the power user electric energy data acquisition system (2013 version) to support corresponding power line carrier intelligent electric energy meter and I/II type power line carrier collector to form an internet, realizing the bidirectional communication between concentrator and intelligent electricity meter and completing the data collection of onsite meter.

The power line carrier module of electricity meter can be directly embedded in the low-voltage type I collector or single-phase intelligent electricity meter in line with the standard of the power user electric energy data acquisition system (2013 version) to support the type I concentrator of local communication unit of corresponding power line carrier to form an internet, realizing the bidirectional communication between concentrator and intelligent electricity meter and completing the data collection of onsite meter.

● Point-to-point communication is over 800m.

●Adopting flooding dynamic networking technology with completely independent intellectual property rights which supports plug and play and is maintenance-free.

● The software is configurable with carrier communication ranging from 3 to 500kHz and supports double frequency mode.

● It can be self-adapted to rate of data signaling from 100-55kbps.

●  It adopts BPSK modulation demodulation system with better disturbance-resisting capacity than FSK, and its chips adopt convolutional encoding of 1/2 and 3/4 code rates and circular interweaving technology so that it can decode correctly even in conditions with terrible background noise of power lines.

● It can be upgraded remotely by way of online radio.

● High reliability, maintenance-free, low delay and convenient operation.

● Standard physical design which supports plug and play and hot plug.
