摘要

PROBLEM TO BE SOLVED: To provide a remote meter reading system allowing a master station to obtain measurement information from plural slave stations connected to different distribution lines.SOLUTION: The remote meter reading system comprises: a slave station 10; a master station 20; an upper aggregation server 40; and a distribution line 50. Plural slave stations 10 are provided to read the amount consumed at each consumer of a supplied medium which is purchased from a supplier through a supply device. Plural distribution lines 50 are provided and the slave stations 10 are connected to the respective distribution lines 50. The master station 20 is connected to any one of the distribution lines 50 and communicates with the slave stations 10 connected to the relevant distribution line 50; to thereby collect the measurement results read by the slave stations 10. The master station 20 notifies the read information based on the measurement results to the upper aggregation server 40 via communication network 51. Also, the upper aggregation server 40 obtains a measurement result from a specific slave station 10 via the master station 20.
