PLC AMI Complexed power metering systme using wired/wireless Advanced Metering Infrastucture device based on Power line communication

摘要

The present invention relates to a technique for integrally detecting information provided by a plurality of meters using various types of communication media and communication methods. An electric power data metering method comprises: a first step of, by a main metering device, transmitting a command message to start metering of a plurality of Zigbee sub-meters to the plurality of Zigbee sub-meters capable of performing Zigbee communication with the main metering device and transmitting a command message to start metering of a plurality of sub-metering device sub-meters, which are capable of performing power line communication with a sub-metering device, to the sub-metering device capable of performing Zigbee communication with the main metering device; a second step of, by the main metering device, transmitting a Zigbee sub-meter metering data request list to the plurality of Zigbee sub-meters; a third step of, by the main metering device, sequentially receiving Zigbee sub-meter metering data through Zigbee communication; a fourth step of, by the main metering device, transmitting a sub-metering device sub-meter metering data request list to the sub-metering device; and a fifth step of, by the main metering device, sequentially receiving the sub-metering device-sub-meter data through Zigbee communication.
