  • Advanced metering infrastructure system for guaranteeing reliable transmission of meter data and advanced metering method using the same
    Patent number: 8957784
    Abstract: Disclosed herein is an advanced metering infrastructure system that includes electronic meters, each of which being configured to measure and store an amount of energy consumed by each customer and provided with a slave communication modem, a data concentrator for collecting meter data from the electronic meters via a master communication modem that performs wired/wireless communication with the slave communication modems of the electronic meters, and a meter reading server for receiving and managing the meter data collected by the data concentrator. The master communication modem and each of the slave communication modems implement mutual communication interfaces using a protocol stack. The protocol stack includes a network layer, an application layer, and a modem performance analysis layer disposed between the network layer and the application layer and configured to analyze quality of a communication link between the master communication modem and each slave communication modem.
