The invention discloses a method, a
system and equipment for
power line communication data processing. The
system comprises a
transmitter and a
receiver. The
transmitter comprises a first
peak detection module, a channel coding module, a modulation module and a transmission front-end module, wherein the first
peak detection module is used for peak point detection and
voltage peak point forecast, the channel coding module is used for channel coding, the modulation module is used for modulation of bit
stream data output by codes, and the transmission front-end module is used for beginning to transmit
power line communication data from a peak time point acquired by detection and continuing for a period of time T. The
receiver comprises a second
peak detection module, a channel decoding module, a
demodulation module and a receiving front-end module, wherein the second peak detection module is used for
voltage peak point detection and peak point forecast, the channel decoding module is used for channel decoding, the
demodulation module is used for
demodulation of demodulation signals, and the receiving front-end module is used for beginning to receive the
power line communication data from the peak time point acquired by the detection, continuing for the period of time T, and transmitting the power line communication data to the demodulation module for demodulation after synchronization. According to the method, the
system and the equipment for the power line communication
data processing, bandwidth of power-line communication is greatly improved, and the number of available carrier
waves in the communication is increased.
