Embodiment Construction

[0034] Figure 1A A communication system in a smart meter automation remote management environment is schematically shown.

[0035] Figure 1A The system shown in includes a power line communication network (indicated by solid arrows) designed to interconnect smart meters and enable them to communicate with the underlying nodes to send them, inter alia, meter readings, which are here It is called MNC (Multimedia Network Connection Coordinator) device 110 . In this context, the term "multimedia" means "multiple connected devices" in its etymology. The power line communication network is meshed, which enables any one smart meter to have multiple paths potentially available to the MNC device 110, and vice versa. In such a mesh network, some nodes then act as repeaters to enable one or more other nodes to communicate with the MNC device 110 . A "node" refers to any device that can be included in a system to communicate with other devices in the system.

[0036] The MNC device 1...

Abstract

A system comprising a power line communication network with a reactive routing protocol and at least one gateway (121) including a power line communication interface and at least one radio frequency communication interface. A smart meter (116) also comprising a power line communication interface and at least one radio frequency communication interface: broadcasting a notification request message on each of its communication interfaces; after receiving one or more notification messages, selectively connecting to a centralized management device The relay agent with the lowest routing cost (121); and using the selected relay agent as a proxy to issue a registration request. After registration, the routing of messages from or to the smart meter takes place in the data link layer of the OSI model.

Description

technical field [0001] The invention relates to the connection of a smart electricity meter comprising a power line communication interface and at least one radio frequency communication interface to a system comprising a power line communication network with a reactive routing protocol. Background technique [0002] Over the past few years, power line communication networks for AMM (Automatic Meter Management) type systems have emerged. For example, mention may be made of the G3-PLC standard specified in ITU-T Recommendation G.9903. In such a power line communication network, communication is established between electricity meters known as "smart meters" and a central device sometimes called an "infrastructure node" or "coordinator" to specifically allow automated remote reading by said Electricity consumption measurement by a smart meter. Multiple base nodes are then deployed geographically to distribute the load as metering readings are collected from smart meters. Eac...
