Problems solved by technology

However, the observation that in most applications the accuracy of the information is not decisive, a simple estimate of the electrical power consumed already makes sense, thus opening the door to the development of simple and therefore inexpensive devices

Embodiment Construction

[0053] In the remainder of this instruction manual:

[0054] -Short distance refers to tens of meters indoors and up to 300 meters outdoors. For example: ZigBee, ZigBee Green Energy, Bluetooth, BLE (Bluetooth Low Energy), WiFi, etc.;

[0055] - Long range index km. Especially LPWAN technologies that include for example LoRa and SigFox type networks.

[0056]The invention relates to an electrical energy metering device that operates over a wireless communication network to allow sending messages, for example, to a central station intended to manage the electrical energy of an electrical grid (of the "smart grid" or "smart city" type). Preferably, the communication network is a low-rate long-distance communication network of the LPWAN (ie "Low Power Wide Area Network") type based on protocols such as LoRaWAN (ie "Long Range Wide Area Network") or protocols developed by SigFox or Qowisio.

[0057] The energy metering device of the invention has the form of a box, for example c...

Abstract

An electricity metering device is provided. The present invention relates to an electricity metering device intended to be associated with an electrical conductor (20) for the purpose of generating measurement data linked to the electric current flowing through said electrical conductor (20). The device includes in particular: a primary electricity storage unit (30) that is arranged so as to storean amount of electrical energy; a secondary electricity storage unit (31) that is connected to said primary storage unit (30); switching means (S2) that are controlled by the processing unit in orderto trigger a transfer of energy from said primary storage unit (30) to said secondary storage unit (31) and in order to trigger a supply of power to a wireless data transmitter (40) when a thresholdof the voltage across the terminals of the secondary storage unit (31) is crossed with a view to transmitting a message containing data representative of the electric current flowing through said electrical conductor (20).

Description

technical field [0001] The invention relates to an electrical energy metering device intended to be connected to an electrical conductor to generate measurement data about the current flowing through said electrical conductor and to transmit said data to eg a remote central station via a wireless communication network. The device of the invention has the advantage of being electrically independent by means of inductive energization by means of a current flowing through the electrical conductor. Background technique [0002] Power management solutions to improve the energy efficiency of infrastructure are increasing, and they need to determine the power consumed by each device of the infrastructure. To this end, in particular different types of equipment are used, suitably arranged at different points of the infrastructure to measure the current and possibly determine other parameters. Various measurement data items are sent to a remote central station via a wireless communi...
