REMOTE METER READING SYSTEM AND METHOD USING MULTIPLE MASTER DEVICES

摘要

This specification relates to a remote meter reading system using a plurality of master devices and a remote meter reading method thereof, and more particularly, a remote meter reading system using a plurality of master devices, capable of allowing for communication with another electricity meter modem which can replace one electricity meter modem when there is a trouble in communication between the one electricity meter modem and the master devices, allowing for fast and flexible reaction with respect to changes in communication network between the electricity meter modem and the master devices, and constructing a network path for communication with an optimal communication performance, all by way of enabling network connection and information sharing among master devices through communication between electricity meter modems and the plurality of master devices, and a remote meter reading method thereof.

主权项

1. A remote meter reading system using a plurality of master devices comprising:
an electricity meter unit that is provided with a plurality of electricity meters each configured to read an amount of electricity energy; an electricity meter modem unit that is provided with a plurality of electricity meter modems each configured to obtain meter reading data from the electricity meter unit and to generate communication information; and a master device unit that is provided with a plurality of master devices each configured to collect the meter reading data and perform communication with the electricity meter modem unit based on the communication information, wherein the plurality of master devices construct a network path for communication with the electricity meter modem unit by mutually sharing the meter reading data and the communication information and perform communication with the electricity meter modem unit along the network path.
