US 2015/0146764 A1 · REPEATER FOR POWER LINE COMMUNICATION AND REPEATING METHOD THEREOF

Abstract

The present disclosure relates to a repeater for power line communication, capable of preventing a ping-pong phenomenon and a loss of data packet and improving communication reliability and communication speed by allowing a power line communication terminal to add its repeater number in a received data packet for transmission, and a repeating method thereof. A repeater for power line communication according to the disclosure comprises a power line communication concentrator to execute communication through a power line, and a plurality of power line communication terminals including a plurality of repeating power line communication terminals each having a repeating function and a repeater number set therefor, and configured to execute the communication with the power line communication concentrator through the power line, wherein the plurality of repeating power line communication terminals receive data packets, and repeat the data packets by adding their own repeater numbers in the data packets, respectively.

A repeater for power line communication comprising:

a power line communication concentrator that is configured to execute communication through a power line;
and
a plurality of power line communication terminals that include a plurality of repeating power line communication terminals each having a repeating function and a repeater number set therefor, the plurality of power line communication terminals executing the communication with the power line communication concentrator through the power line,

A repeating method for power line communication comprising:

a repeater number setting step of setting a command repeater number and a response repeater number for each of repeating power line communication terminals of a plurality of power line communication terminals, which communicate with a power line communication concentrator;
a data packet receiving step of checking by each of the power line communication terminals address information included in a data packet and deciding whether or not the address information is its own address when the data packet is received by each of the plurality of power line communication terminals;
a repeating function setting deciding step of deciding by each of the plurality of power line communication terminals whether or not a repeating function has been set therefor, when it is decided that the address information is not its own address;
and
a data packet deciding step of deciding by each of the plurality of power line communication terminals whether the data packet is a command data packet or a response data packet when it is decided in the repeating function setting deciding step that the repeating function has been set,
wherein it is decided whether or not the repeater number is added in the data packet according to the data packet deciding step, wherein the power line communication terminal received the data packet adds its own repeater number in the data packet and then outputs the data packet when the repeater number is not added in the data packet.
