Title:
WIRELESS COMMUNICATION METHOD OF INTELLIGENT ADVANCED METERING INFRASTRUCTURE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/013545
Kind Code:
A1
Abstract:
The present invention relates to a communication method applied to an intelligent advanced metering infrastructure (AMI) system so as to enable metering data collected from an electronic power meter to be wirelessly transmitted to a coordinator via routers, and relates to a technique enabling communication via channels having excellent communication qualities. Such present invention comprises the steps in which: routers check channel quality data for a currently used channel and idle channels, and transmits the results of the checking and GPS data of the routers themselves to a coordinator; the coordinator checks, on the basis of the channel quality data, whether or not handoff requirements are met; and if, as a result of the checking, the coordinator determines that handoff requirements are met, the coordinator issues, to the routers, a channel change command ordering for the currently used channel to be changed to the idle channel having the most excellent communication quality.
