Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a device, system and method for processing and displaying data from a household energy consumption meter. It applies, in particular, to the processing of information from new generation electric meters.

STATE OF THE ART

New generation electric meters, known as “smart” meters, are capable of supplying electricity consumption information to a distributor by means of carrier current.

To remotely read their electricity consumption, a user can implement:

- an optical reading system detecting a light pulse per kWh or the turn of a metric disc or

- an amperomagnetic clamp system, positioned upstream or downstream of the meter, making it possible to measure a magnetic field passing through electrical cables to deduce an energy consumption.

These systems are unreliable, expensive and cumbersome.

The company Enedis (Registered trademark) markets a new generation meter named Linky (Registered trademark), the most recent models of which have three outputs, grouped under the name "Tele-Information Client output" (abbreviated as "TIC").

Today, it is impossible for a consumer of electrical energy to remotely record their electrical consumption from electronic information emitted by a meter.

FIG. 1, which is not to scale, shows a schematic view of an embodiment of the device 100 which is the subject of the present invention. These measures

100 for processing and displaying data from a 200 home energy consumption meter, includes:

an electrical connection 105 with three legs, 110, 115 and 120, configured to be brought into contact with an electrical connection 205 with three outputs, 210, 215 and 220, of the meter,

- an electronic converter 125 of information, contained in signals picked up by the connection, into wireless signals to be transmitted and

- a transmitter 130 of the wireless signals converted intended for a communicating portable terminal.

The connection 105 is, for example, a set of electric cables, the ends of which, called "legs", are mechanically connected to the counter 200 on the one hand and to an electronic card supporting the converter 125 and the transmitter 130 on the other hand .

The three outputs, 210, 215 and 220, are for example formed by an ICT output from the Linky counter from the company Enedis. For this type of counter:

- one of these outputs corresponds to the mass,

one of these outputs corresponds to a supply, this supply being configured to emit a signal having a voltage of 6V, and

- the last output corresponds to an output of information recorded by the counter 200, the information being transmitted at a frequency of 50KHz.

In particular embodiments, one of the tabs 105 is an electrical supply tab connected to a supply outlet of the counter 200.

The electronic converter 125 is, for example, a computer program executed by a microprocessor positioned on the electronic card associated with connection 105.

This converter 125 receives frames received by connection 105 according to the format of the frames of the counter 200 and converts these frames into frames compatible with the transmission technology implemented by the transmitter 130.

In particular embodiments, the converter 125 includes a filter 145 of information contained in the received signals, only the unfiltered information being converted into wireless signals.

In particular embodiments, the device 100 is configured to send a request for consumption information, towards the counter 200, according to a period greater than or equal to two seconds.

The filter 145 is, for example, a software filter executed by the microprocessor configured to analyze the information contained in each frame received by the connection 105 and for, as a function of information contained in each frame, to filter or not the frame before converting this frame.

In variants, the filter 145 is positioned at a server 500, as described with reference to FIG. 2, and filters the information transmitted to the terminal 300. In these variants, the raw information transmitted by the counter 200 is transferred to the server 500. The configuration of this filter 145 can be automatic or controlled by the terminal 300.

îo In variants, the filter 145 is positioned at a terminal 300, as described with reference to FIG. 2, and filters the information transmitted to the server 500 or coming from this server 500. In these variants, the raw information emitted by the counter 200 are transferred to the terminal 300 which may or may not transmit this data to the server 500. The configuration of this filter 145 can be automatic or controlled by the terminal 300.

In other variants, the filter 145 is positioned at the terminal 300, the counter 200 communicating raw data to the device 100, this data being transmitted raw to the server 500, then from the server 500 to the terminal 300, the terminal 300 filtering the data.

The transmitter 130 is, for example, an antenna configured to transmit wireless signals via a point-to-point link or via an IP type data network (for “Internet Protocol”, translated by “Protocol internet> >) or of cellular data network type.

This transmitter 130 implements, for example:

- the IEEE 802.11 standard, known as "WiFi",

- the Bluetooth standard, and in particular the so-called “BLE” standard (for “Bluetooth Low Energy”, translated by “Bluetooth low energy”) also known as “Bluetooth 4.0” or

- NFC technology (for “Near Field Communication”, translated by “Near Field Communication”).

Preferably, the Bluetooth standard is implemented.

In particular embodiments, the transmitter 130 is configured to transmit signals periodically, according to a period greater than or equal to two seconds.

The choice of transmission frequency depends on the power consumption desired for the device 100. The higher the transmission frequency, the higher the power consumption of the device 100.

The transmitted data are sent to a remote server or to a communicating terminal near the device 100.

In particular embodiments, the device 100 includes a capacitor 135 charged by the power supply tab.

This capacitor 135 supplies the converter 125 and / or the transmitter 130 to compensate for the shortcomings of the power supplied by the counter 200.

îo In particular embodiments, the device 100 includes a memory 140 buffering the information contained in the signals picked up by the connection 105.

This memory 140 has, for example, a storage capacity of 256 bytes.

This memory 140 is preferably integrated into the microprocessor implementing the converter 125. In this way, the memory 140 is integrated into the microprocessor and the device 100 does not require an external memory. This memory 140 is used to temporarily store the data received from the counter 200 before transmission by the transmitter 130, after this data has been converted by the converter 125.

In particular embodiments, the device 100 includes an external output 150 configured to receive a data transmission cable.

This external output 150 is, for example, a USB output (for "Universal

Serial Bus ”, translated as“ Universal serial bus ”) or mini-USB type B.

This USB output allows the device 100 to present a so-called “sniffer” mode, which makes it possible to collect all the data from the counter 200.

If a USB cable connects this USB output to a terminal, such as a computer for example, the information collected can be viewed.

The supply of the external output 150 is carried out either through the supply output of the counter 200, or by a supply supplied directly by the cable connected to the external output 150 to the device 100. Such a type of supply is well known in the context of a USB connection.

The request sent by the transmitter 310 is, for example, a request for information representative of an energy price as a function of a type of energy contained in the information received by the receiver 305.

The types of energy depend, for example, on the hour of energy consumption, the price of this energy varying according to the hour of consumption.

In variants, the consumption information is stored at the level of the server 500.

The reception means 315 is, for example, an antenna configured to implement a technology complementary to the technology implemented at the level of a transmitter (not shown) of the server 500.

The screen 320 allows the display of an interface of software embedded in the terminal 300, this interface presenting representative information:

- of an overall electrical consumption measured for a determined period at the level of the meter 200,

- an electrical consumption measured in real time or cumulative from a given instant,
