REMOTE METER READING SYSTEM, READING METER, MAIN TERMINAL, AND COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a remote meter reading system, reading meter, main terminal, and communication method for making it possible to perform multi-hop communication using the reading meter, even when arrangement of an electrification area and outage area is changed.SOLUTION: Each of a plurality of reading meters 2 operates using commercial power and transmits meter reading data on commercial power of each user C existing in each of a plurality of areas B by multi-hop communication. Each of the areas B is, for each time zone, set as an electrification area in which commercial power is supplied or outage area in which commercial power is not supplied. Each of the plurality of reading meters 2 leads out a communication root to be established between the reading meter and a main terminal 1 for each time zone, on the basis of power supply information acquired from a management server CS through the main terminal 1.
