Abstract

The invention provides a power line broadband carrier communication method which can improve the communication reliability. The method comprises the following steps: dividing a broadband carrier communication frequency band into a plurality of subchannels at different frequency bands; detecting the interference and noise on a power line, and performing statistics on the frequency band subchannelswith interference and noise; transmitting data on the frequency band subchannels of which the sum of interference and noise does not exceed a first threshold. The invention relates to the field of carrier communication.

Description

technical field [0001] The invention relates to the field of carrier communication, in particular to a power line broadband carrier communication method. Background technique [0002] At present, in the power system, the communication between the energy meter, the collector and the concentrator mainly includes: wireless micropower communication and narrowband carrier communication. [0003] Wireless micropower communication technology is seriously affected by obstacles such as weather and buildings, and the reliability of transmission signals is poor; narrowband carrier communication technology communicates in the 10kHz-500kHz frequency band, and has unavoidable technical bottlenecks in terms of noise and impedance. Poor anti-interference ability. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a power line broadband carrier communication method to solve the problems of poor reliability and poor anti-interferenc...
