Description

technical field

[0001] The invention relates to a carrier communication device, in particular to a network data conversion device based on power line carrier communication. Background technique

[0002] In the prior art, there are mainly two methods based on power line carrier communication: one is to use a low-speed power line communication architecture with a frequency of 7KHZ-500KHZ, which is a narrowband communication method. The communication rate of this method is very low, usually less than 9600bps, generally Only 1200bps, because the signal-to-noise ratio of power line communication is difficult to be stable in the changing power consumption environment, it cannot be well guaranteed, so the success rate of communication is low and the reliability is poor, but the transmission distance is long, up to a kilometer.

[0003] Another method based on power carrier communication is to use broadband communication and use orthogonal frequency division technology (OFDM). The ...
