Method, carrier equipment and system for realizing Ethernet data exchange of power line

Abstract

The invention discloses a method, carrier equipment and system for realizing Ethernet data exchange of a power line. The method comprises the steps as follows: an Ethernet message sent by local external connection equipment is received, and a target MAC (media access control) address of the Ethernet message is obtained; whether the target MAC address is in a local MAC address list which is established in advance is determined, if yes, the Ethernet message is abandoned, and otherwise, whether the target MAC address is in a far-end MAC address list which is established in advance is determined; and if the target MAC address is in the far-end MAC address list, and carrier equipment corresponding to the target MAC address is obtained from the far-end MAC address list, so that the Ethernet message is forwarded to the corresponding carrier equipment. With the adoption of the scheme, the efficiency of the Ethernet data exchange in a power line communication system is improved.

Description

technical field [0001] The invention relates to the field of grid communication, in particular to a method, carrier equipment and system for realizing power line Ethernet data exchange. Background technique [0002] Power line carrier communication technology is a communication method that uses power lines as a communication medium to transmit data information. It realizes data, voice, video, etc. transmission. Through the erection of the distribution network, the power lines have been distributed to thousands of households. Therefore, using the carrier communication of the power lines, the communication between service providers at all levels and household meters, water meters, and gas meters can be realized. The power line carrier technology uses the power line as the transmission channel. It is the only wired communication method in the power system that does not require additional line investment. It is economical, stable, reliable, and not easy to damage. [0003] In ...

AI Technical Summary

Problems solved by technology

[0003] In the existing power line carrier communication system, after the carrier device receives the Ethernet message sent by the local external device, it usually sends the Ethernet message of the local external device to the power line in the form of message multicast, so as to Realize the data exchange between the local external device and the remote external device connected to other carrier devices, and the communication efficiency is low
