AUTOMATIC METERING METHOD/DEVICE

摘要

PROBLEM TO BE SOLVED: To provide automatic metering method/device which arbitrarily enlarge the automatic metering areas of various meters and which have extendibility. SOLUTION: A first group G0 is formed at plural houses to which a power line PL is pulled in through the same transformer 10. A second group G1 is formed at plural houses to which a power line PL is pulled in through the other transformer. The power line belonging to the first group GO is connected with the power line belonging to the second group G1 through connection devices 70a and 70b in terms of high frequency. The meter values of the meters arranged in the houses of the second group G1 are collected with the meter values of the meters arranged in the houses of the first group by using power line communication through the connection devices 70a and 70b.
