US 2020/0007191 A1 · METHOD FOR TRANSPORTING LORA FRAMES ON A PLC NETWORK

Abstract

Method for transporting LoRa frames over a first PLC communication network of a system for the automated management of meterings from a plurality of electricity meters, referred to as meters, said meters in the plurality being attached to at least one data concentrator via the first network, each data concentrator being connected to a server via a second network and serving as a relay between said meters and the server. The method is executed by a meter in the plurality and comprises: receiving (402) a LoRa frame, each LoRa frame received corresponding to the same LoRa frame sent by an endpoint; relaying a received LoRa frame, referred to as the first frame, corresponding to said sent frame, in the direction of the server, the first frame being selected (403) in accordance with a first predetermined criterion; when a plurality of LoRa frames corresponding to said sent LoRa frame are received, rejecting at least a subset of LoRa frames in the plurality of frames different from the first frame.

A method for transporting frames sent by endpoints over an LPWAN network by means of a first so called AMM powerline communication network (101) of a system for the automated management of meterings from a plurality of electricity meters, referred to as meters, said meters in the plurality of meters being attached to at least one data concentrator via the AMM network, each data concentrator being connected to a server via a second network and serving as a relay between said meters and the server, wherein said method is executed by a meter in the plurality of meters and comprises:

receiving at least one frame in accordance with a communication protocol suited to LPWAN networks, each frame received corresponding to the same frame sent over the LPWAN network by an endpoint;
relaying a received frame, referred to as the first frame, corresponding to said sent frame, in the direction of the server, the first frame being selected in accordance with a first predetermined criterion;
when a plurality of frames corresponding to said sent frame are received, rejecting at least a subset of frames in the plurality of frames different from the first frame, each frame in the subset being selected in accordance with a second predetermined criterion.

A device of the electricity meter type included in a first system, referred to as an AMM system, for the automated management of meterings from a plurality of electricity meters, said meters in the plurality of meters being attached to at least one data concentrator via a first powerline network, each data concentrator being connected to a server via a second network and serving as a relay between said meters and the server, wherein said device comprises electronic circuitry adapted for:

relaying, in the direction of the server, a frame, referred to as the first frame, received by the device, corresponding to a frame in accordance with a communication protocol suited to LPWAN networks sent by an endpoint over an LPWAN network, the first frame being selected in accordance with a first predetermined criterion;
and
rejecting at least a subset of frames in the plurality that are different from the first frame when a plurality of frames corresponding to said sent frame are received, each frame in the subset being selected in accordance with a second predetermined criterion.
