Embodiment Construction

[0034] In view of the great randomness and uncertainty in the topological structure of the existing power grid and the connected electrical equipment, and the strong time-varying nature of the power line channel, the existing communication equipment cannot be selected for the current application Appropriate communication methods, so that the reliability of its communication is greatly affected, and the spectrum utilization rate and power consumption utilization rate are relatively low.

[0035] Therefore, the inventors of the present invention have improved the prior art, including: recognizing the power line channel and obtaining the channel model, determining the configuration parameters of the communication device, thereby reconfiguring the communication transceiver in the communication device, through the configured Communication equipment for data transmission makes the entire power line communication system work in the most suitable state, thereby improving the reliabilit...

Abstract

The invention provides power line communication equipment based on a channel cognitive technology. The equipment comprises: a power line communication transceiver, which has a configurable parameter; a channel cognitive module, which is used for carrying out cognition on a power line channel and obtaining a channel model; and a cognitive control module, which is used for carrying out learning according to the channel model obtained by the channel cognitive model so as to determine and configure a configuration parameter of the communication transceiver in the communication equipment. Compared with the prior art, the technology employed in the invention enables a configuration parameter of a communication transceiver in the power line communication equipment to be configured, so that a whole power line communication system can work in the most suitable state and thus reliability, stability and a communication speed of the power line communication are improved; meanwhile, a frequency spectrum utilization rate and a power consumption utilization rate can be improved.

Description

technical field [0001] The present invention relates to a communication technology, in particular to a power line communication device 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 contr...
