Embodiment 1

[0035] Such as figure 1 As shown, a method for reducing dynamic power consumption in power line carrier communication in this embodiment includes the following steps:

[0036] In the sending step, the node sends data to the other node according to the preset power;

[0037] In the acceptance step, the node generates an evaluation amount according to the returned information of the peer node;

[0038] Calculate the adjustment step, the node adjusts the transmission power according to the generated evaluation amount;

[0039] Wherein, the calculation adjustment step includes a signal-to-noise ratio adjustment step, and the signal-to-noise ratio adjustment step specifically includes:

[0040] S101: The node acquires the transmission signal-to-noise ratio and uses the signal-to-noise ratio as an evaluation quantity;

[0041] S102: The node generates a target transmit power according to the signal-to-noise ratio;

[0042] S103: The node adjusts the current power according to th...

Embodiment 2

[0048] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the calculation adjustment step includes an error rate adjustment step, and the error rate adjustment step includes:

[0049] S201: The error rate sent by the node according to the statistical information of the returned information, using the error rate as the evaluation amount;

[0050] S202: Determine whether the current error rate is greater than the maximum threshold, if yes, increase the transmission power, and execute S202 again, if not, execute S203;

[0051] S203: Determine whether the current error rate is less than the minimum threshold, if yes, reduce the transmission power, and re-execute S202, if not, end the error rate adjustment step.

[0052] For example, the current sending power is Pt, the error rate of the current packet returned by SACK is Per, the maximum threshold is PerHigh, and the minimum threshold is PerLow. Then if Per>PerHigh, then increase the Pt, ...

Embodiment 3

[0056] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 and Embodiment 2 is that the calculation adjustment step includes both the SNR adjustment step and the error rate adjustment step, and the SNR adjustment step is before the error rate adjustment step.

Abstract

The invention relates to the technical field of the power line carrier communication, specifically a method for reducing dynamic power consumption in the power line carrier communication. The method comprises the following steps: a sending step, the node sends data to an opposite-side node according to the preset power; a receiving step, the node generates assessment scale according to return information of opposite-side node; a computing adjusting step, the node adjusts the transmitting power according to the generated assessment scale, wherein the computing adjusting step comprises a signal-to-noise ratio adjusting step and an error rate adjusting step, the signal-to-noise ratio adjusting step comprises S101, the node acquires the transmission SNR and takes the SNR as the assessment scale; S102, the node generates the target transmitting power according to the SNR; and S103, the node adjusts the current power according to the target transmitting power. Through the method for dynamically reducing power consumption in the power line carrier communication, the problem that the existing line carrier communication is large in power consumption can be solved.

Description

technical field [0001] The present invention relates to the technical field of power line carrier communication, in particular to a method for reducing dynamic power consumption in power line carrier communication. Background technique [0002] Power line carrier communication (power line carrier communication) is a power system communication in which the transmission line is used as the transmission medium of the carrier signal. Since the power transmission line has a very strong support structure and more than 3 conductors (generally there are three-phase good conductors and one or two overhead ground wires), it is economical to use the power frequency current to transmit the carrier signal at the same time as the transmission line And very reliable. This kind of comprehensive utilization has already become the unique communication means adopted by all electric power departments in the world. [0003] With the application of power line carrier communication technology mo...
