Document Type and Number:
Japanese Patent JP5874023
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a remote meter reading system enabling one key station to acquire measurement information from slave stations each connected to a plurality of transformers so as to suppress an introduction cost and reduce a traffic.SOLUTION: A slave station 10 acquires a used power amount of a user from an electricity meter 11. A key station 20 and a relay master station 30 can communicate with the slave station 10 by a power-line carrier communication using a distribution line 50 as a communication channel so as to collect meter reading data acquired by the slave station 10. The relay master station 30 communicates with the key station 20 using radio communication to notify the key station 20 of the meter reading data collected from the slave station. The key station 20 aggregates the meter reading data from the slave station 10 directly connected thereto through the distribution line 50 and the meter reading data from the slave station 10 via the relay master station 30 so as to notify an upper aggregation server 40 of the meter reading information through a communication network 51.
