Collector
Adopting the BPSK modulation and demodulation system, the three-phase carrier module has a disturbance-resisting capacity apparently better than FSK. The chip employing the 1/2 and 3/4 code rate convolutional encoding and cyclic interleaving technology can still correctly decode under the high volume of background noise of electric power line.
● 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, free of maintenance, low delay and convenient operation.
