Power line communication quality evaluation method and the power line communication system

摘要

PROBLEM TO BE SOLVED: To provide a power line communication evaluation method and a power line communication system, with which communication quality is simply evaluated, and evaluation results is easily shared among a plurality of nodes in power line communication.;SOLUTION: The power line communication system is constituted of the plurality nodes 12, 14, 16, 18 connected to a power line 10, transmits data from one node 12 and in that case, transmits the data by attaching information indicating n-th transmission of the data. Each of the nodes 12, 14, 16, 18 connected to the power line 10 is provided with a reception confirmation signal circuit 28 and a transmitting circuit 24, which receive the data from one node 12 to transmit its reception confirmation signal. The reception confirmation signal circuit 28 transmits the number of transmissions and information indicating a transmitted data amount together. Each of the nodes 14, 16, 18 for performing the power line communication is provided with a communication quality evaluation circuit 26 which evaluates the communication quality of the power line communication on the basis of a value obtained by receiving the number of transmissions and the data amount of the reception confirmation signal and dividing the data amount by the number of transmissions.;COPYRIGHT: (C)2009,JPO&INPIT
