Abstract

The invention provides a power line communication method based on a channel cognitive technology, and the method comprises the following steps of: cognizing a power line channel and obtaining a channel module; determining the configuration parameters of a communication device according to the obtained channel model; configuring a communication transceiver in the communication device according to the determined configuration parameters; and executing data transmission via the communication device which is configured with the configuration parameters. Compared with the prior art, the method provided by the invention can be used for configuring the configuration parameters of the communication transceiver in the power line communication device, thus the whole power line communication system can work in the most appropriate state, thereby improving the reliability, stability and communication rate of power line communication and simultaneously improving the frequency spectrum utilization ratio and the power utilization ratio.

Description

technical field [0001] The invention relates to a communication technology, in particular to a power line communication method based on channel recognition technology. Background technique [0002] Power line carrier communication technology is a communication method that uses power lines as a communication medium to transmit data information, generally including: high-voltage power line carrier communication using high-voltage transmission lines with a voltage level of 35kV and above as a communication medium; medium-voltage transmission lines with a voltage level of 10kV as Medium-voltage power line carrier communication of communication medium; and low-voltage power line carrier communication of 380V or 220V low-voltage transmission line as communication medium. [0003] Traditional power line carrier communication mainly uses high-voltage transmission lines as the transmission channel of high-frequency signals, which is limited to the transmission of remote control signa...
