Description

Title of the invention: Method for identifying at least one electrical device in an electrical network. Technical field

[0001] The invention lies in the field of electrical supply networks of a site (for example a residential site, an industrial site, or even a larger site such as a city), and relates more particularly to the management of electrical equipment connected to such networks. Previous art

[0002] Increasingly, a dwelling, or more broadly a site such as a business or a public building, is supplied with electrical energy from several sources. Historically, such a site has been supplied by a so-called high-power source. This electrical supply is, for example, provided by a public electricity supplier through a contract established between the site manager and the public supplier. Thus, depending on the size of the site and its electrical energy needs, a power supply contract is generally established with the electricity provider. For example, a contract might stipulate a power supply of 6 kVA (kilovolt-amperes) for a small site, up to several tens of kVA for the largest sites.

[0003] In addition to this high-power power supply, a lower-power power supply is increasingly being implemented by sites to supplement the high-power supply and, in particular, to reduce the costs associated with the high-power power supply contract. For example, the site deploys solar panels to provide supplementary power to the high-power supply. This supplementary, or low-power, power supply is, for example, provided to the site by solar panels via an inverter, which is responsible for delivering alternating current to the site and regulating the power supply provided by the solar panels.Depending on the capacity of the low-power electricity source, the share of self-consumption in overall consumption, indicating the degree of autonomy of the site in terms of electricity supply, is more or less significant.

[0004] In the event of a failure of the high-power network (for example, due to an overload on the site's main electrical network, intervention by a technician on this network, a storm, etc.), the low-power network may take over to ensure the continued operation of one or more pieces of equipment on the site. However, such a low-power network is generally not sized to ensure the optimal operation of all electrical equipment initially supplied by the high-power network. In such an operating mode, where only low-power supply remains available—in what can therefore be described as a "degraded" operating mode—the presence of a first, particularly power-consuming piece of electrical equipment is likely to impair the proper functioning of a second piece of electrical equipment, the first piece of equipment drawing the majority of the available power. However, in certain situations, the proper functioning of this second piece of equipment may be of higher priority than that of the first, for example, for reasons of public safety. For example, in the event of a high-power network outage caused by a potentially dangerous weather event (storm, wind, flood, etc.)...Therefore, ensuring the proper functioning of electrical equipment such as a radio signal relay device (like a Wi-Fi repeater) or access gateway (or "box") can be considered a priority, compared to, for example, comfort equipment such as a wine cellar, in order to ensure continuous network connectivity for equipment and individuals located on or near the site. This way, people affected by a disaster are not isolated and retain means of communication with the outside world, for example with intervention teams (medical, assistance, etc.).

[0005] In such a situation, particularly when faced with such sometimes difficult conditions, a user who notices a malfunction of critical electrical equipment may not necessarily be aware that this malfunction could be attributable to the presence of other interfering electrical equipment connected to the same backup power supply. Thus, while the observed malfunction of the critical equipment could be quickly resolved by a few simple actions that the user could perform themselves (e.g., disconnecting other devices), they remain helpless in the face of the problem due to a lack of information.

[0006] The present invention aims to resolve all or part of the aforementioned drawbacks. Summary of the invention

[0007] The present technique offers a solution to overcome certain drawbacks of the prior art. In one aspect, the present technique relates to a method for identifying at least one electrical device among a set of electrical devices supplied by a power source via the same power line. Such a method comprises:

[0008] - the triggering of a transmission, on said power supply line, by said power supply, of an electrical signal of predetermined characteristics, called the input electrical signal;

[0009] - obtaining, at the level of said power supply line, a response said set of electrical equipment, said electrical input signal, delivering composite information representative of an electronic signature associated with said set of electrical equipment;

[0010] - identification, based on said composite information, by a model identification of electrical equipment, of at least one electrical piece of equipment from said assembly.

[0011] In this way, the method according to the present technique offers a means of automatically identifying, at the level of an electrical network, one or more electrical devices connected to a power line, based on electronic signatures associated with these devices. The method is all the more relevant as it is valid regardless of the number of electrical devices connected to the power line. It thus facilitates the identification and, consequently, the intervention, repair, or replacement of electrical devices on the line. The composite information, once processed and used by means of a model, for example, available in a database, makes it possible to unambiguously identify one or more devices on the line.

[0012] In a particular embodiment, said triggering is implemented upon detection of a switchover of said electrical equipment assembly from a previous power supply source to said power supply source.

[0013] In this way, the automatic identification procedure for electrical equipment is implemented, for example, upon detection of a change in the power source for the electrical network supply, such as when a backup power supply is required to take over from a failed main power supply. The inventory of electrical equipment connected to the network then makes it possible to identify electrical equipment whose operation could have a disruptive effect on the operation of other equipment, or whose operation could be impaired, following changes in the characteristics of the power supply to this electrical equipment caused by the change in the power source (for example, a switch from a high-power source to a low-power source).

[0014] In a particular embodiment, said predetermined characteristics of the input electrical signal include:

[0015] - a voltage between 90V and 300V;

[0016] - an intensity between 1mA and 2A;

[0017] - a frequency between 0Hz and 100Hz.

[0018] In this way, the characteristics of the input electrical signal are close to the usual characteristics of conventionally implemented electrical networks, which facilitates its transmission and the compatibility of equipment with such characteristics.

[0019] In a particular embodiment, said method comprises, after said identification of at least one electrical equipment, obtaining at least one piece of information associated with said at least one identified electrical equipment, within a dedicated data structure. According to a particular feature, said at least one piece of information thus obtained comprises data representative of a type of said electrical equipment and data representative of the electrical consumption of said electrical equipment.

[0020] In this way, many characteristics of an identified electrical device can be obtained automatically, for example from public databases, particularly for subsequent use. Such characteristics may include information considered important in the context of a particular implementation of the method according to the present technique. For example, information on the type of identified device and its power consumption can be obtained, in particular to determine the impact of continuing to operate the device in question in a particular context, especially with regard to other devices powered via the same power supply line.

[0021] In a particular embodiment, said identification method further comprises:

[0022] - the determination of a power supply management policy for said at least electrical equipment, depending on said at least one piece of information obtained;

[0023] - the issuance of at least one message representative of said management policy power supply.

[0024] According to a particular feature, said determination of a power supply management policy further takes into account at least one feature associated with said power supply source.

[0025] In this way, the information on the identified electrical equipment is used, among other data, to define a power management policy, including, for example, notions of priority between devices. Thus, when it is detected, for example, that a low-power backup power supply has taken over from a high-power main power supply, that is to say, in the presence of an unusual situation likely to originate from a dangerous phenomenon (weather event, problem with an infrastructure, etc.), The present technique offers the possibility of prioritizing the maintenance of the operation of devices considered as a priority (e.g., electrical equipment such as a home gateway or a repeater, giving or facilitating access to a communication network) at the expense of the operation of devices considered less essential (e.g., purely comfort devices).

[0026] According to a particular feature, said emission of at least one message representative of said power supply management policy includes the emission of at least one power supply control request to at least one electrical equipment of said set of electrical equipment.

[0027] In this way, the power management policy can be applied automatically, via transmission, to targeted electrical equipment among the identified devices, of requests to switch off, standby, switch on or wake up from standby, depending for example on the priorities between devices defined within the framework of such a policy.

[0028] According to a particular feature, alternatively or complementaryly, said emission of at least one message representative of said power management policy includes a visual and / or audio rendering of at least one instruction for implementing said power management policy.

[0029] In this way, the power management policy is returned to a user, in the form of visual or audio messages emitted on an electronic device to which he has access (for example a communication terminal such as a smartphone), which allows the user to become aware of the changes to the power supply of certain devices which have been implemented automatically, or, failing that, to be informed of recommendations for changes to the power supply of certain devices to be implemented manually.

[0030] In another aspect, the present technique relates to an electronic device for identifying at least one electrical device among a set of electrical devices supplied by a power source via the same power supply line. Such a device comprises:

[0031] - means for triggering an emission on said power line electrical, by said power supply, of an electrical signal of predetermined characteristics, called the input electrical signal;

[0032] - means of obtaining, at the level of said power supply line, a response of said set of electrical equipment to said input electrical signal, delivering composite information representative of an electronic signature associated with said set of electrical equipment;

[0033] - means of identification, based on said composite information, by a model identification of electrical equipment, of at least one electrical piece of equipment from said assembly.

[0034] Such an electronic device may, of course, have the various characteristics relating to the determination method according to the invention, which may be combined or considered separately. Thus, the characteristics and advantages of this device are the same as those of the method for identifying at least one electrical component according to the present technique, and are not described in further detail.

[0035] According to another aspect, the proposed technique also relates to a computer program product downloadable from a communication network and / or stored on a computer-readable medium and / or executable by a microprocessor, comprising program code instructions for the execution of a method for identifying at least one electrical equipment as described above in any of its embodiments, when executed on a computer.

[0036] The proposed technique also relates to a computer-readable recording medium on which is recorded a computer program comprising program code instructions for executing the steps of the process as described above, in any of its embodiments.

[0037] Such a recording medium can be any entity or device capable of storing the program. For example, the medium can include a storage means, such as a ROM, for example a CD-ROM or a microelectronic circuit ROM, or a magnetic recording means, for example a USB flash drive or a hard drive.

[0038] On the other hand, such a recording medium can be a transmissible medium such as an electrical or optical signal, which can be transmitted via an electrical or optical cable, by radio, or by other means, so that the computer program it contains is executable remotely. The program according to the invention can, in particular, be uploaded to a network, for example, the Internet.

[0039] The different embodiments mentioned above can be combined with each other for the implementation of the invention. Figures

[0040] Other features and advantages of the invention will become more apparent upon reading the following description of a preferred embodiment, given by way of simple illustrative and non-limiting example, and the accompanying drawings, among which:

[0041] [Fig.1] presents, in a schematic representation, an example of an electrical network in which a method for identifying electrical equipment according to the proposed technique is likely to be implemented, in a particular embodiment;

[0042] [Fig.2] illustrates the main steps of a process for identifying at least electrical equipment in an electrical network, in a particular embodiment of the proposed technique;

[0043] [Fig. 3] describes a simplified architecture of an electronic device for implementing the proposed technique, in a particular embodiment. Detailed description of the invention

[0044] The present application makes it possible to remedy some of the aforementioned drawbacks.

[0045] In all the figures in this document, the elements and steps of the same nature are designated by the same reference.

[0046] According to a first aspect, the present technique relates to a method for identifying at least one electrical equipment among a set of electrical equipment supplied by an electrical power source via the same power supply line.

[0047] A schematic representation of a simplified electrical network RES is presented first, in relation to [Fig. 1], in which the identification process can, for example, be implemented in a particular embodiment. The electrical network can be supplemented with other devices and components without modifying the process.

[0048] The electrical network RES is supplied by a first high-power energy source SRC1. For example, this high-power energy source is an electricity supplier's network, which consists of a transmission section and a distribution section. Typically, the RES is supplied by a high-power power supply SRC1 providing a power output between 3 kVA and 21 kVA, depending on the needs of the RES network and, in particular, the number of electrical devices in the RES network supplied by SRC1. The RES is supplied by the SRC1 source via a connection system RAC, which includes, for example, an electricity meter responsible for measuring the amount of electrical energy consumed by the various devices in the RES network.Thus, the operator in charge of the SCR1 energy source is able to bill the RES network manager for the amount of energy consumed during a period using the data recorded in the meter. The SRC1 energy source transmits power (W) to the RES network via the RAC connection system.

[0049] The RAC connection system also generally includes one or more electrical safety devices, such as circuit breakers, which may be separate or located alongside the meter. Such electrical safety devices have several roles, such as automatically cutting off the electricity in the event of a short circuit or overvoltage in the RES network, manually cutting off the power supply to the RES network, or limiting electricity consumption to the power level contracted by the RES network operator with the energy source operator SRC1.

[0050] In the example of [Fig. 1], the electrical network RES is also supplied by a low-power alternative or backup electrical energy source, also referred to as the second low-power electrical supply source SRC2. According to this example, this low-power energy is delivered by one or more solar panels providing the RES network with a power p. Alternatively, this power p could, for example, be produced by a wind turbine or by a combination of solar panels and a wind turbine, or even by a battery. The power p supplied by the electrical supply source SRC2 is injected into the RES network via one or more elements of the connection system RAC, including an inverter that regulates the electrical current transmitted to the RES network and transforms the direct current from, for example, the solar panels or the battery into alternating current.Depending on the site's electrical network configuration, the various electrical equipment in the RES network can be powered by the W and / or p power outputs respectively delivered by the first high-power power supply SRC1 and the second low-power power supply SRC2. In certain situations, the second power supply SRC2 can also serve as a backup power supply in case of failure of the first power supply SRC1 (for example, due to a weather event or maintenance work on the high-power network). In the RES network in [Fig. 1], intentionally simplified for clarity, three electrical devices EE1, EE2, and EE3, powered via the same LG power line, are shown as an example.Of course, this example is purely illustrative and not limiting, and other power supply lines, each supplying one or more other electrical equipment, are likely to be present in the RES network.

[0051] The general principle of the method for identifying at least one electrical device among a set of electrical devices is now described in relation to [Fig. 2], as a complement to [Fig. 1], in a particular embodiment. More specifically, as illustrated in [Fig. 1], the electrical devices of said set (three devices EE1, EE2 and EE3 in the case of [Fig. 1]) are powered via the same LG power supply line by a power source, for example, either SRC1 or SRC2. "Set of electrical equipment" here refers to at least one piece of equipment, and usually several. The identification process is implemented, for example, by an electronic device DISP, described later.

[0052] The identification method according to the present technique comprises, in a step 21, triggering the transmission, on the power supply line LG, by the power source that is currently supplying said line LG, of an electrical signal with predetermined characteristics, referred to as the input electrical signal SEE. Such an input electrical signal corresponds to a predefined signal, used specifically in the context of automatic identification operations for electrical equipment within a network. According to a particular characteristic, the input electrical signal is selected from a set of predetermined electrical signals, based on at least one characteristic associated with the power source that is supplying the network at a given time.The input electrical signal may, for example, correspond to a first input electrical signal when the network is powered by the high-power power supply SRC1, and to a second input electrical signal with predetermined characteristics different from those of the first signal when the network is powered by the low-power power supply SRC2.

[0053] In a particular embodiment, the characteristics of such an input electrical signal are selected from classic or notable characteristics of typical domestic alternating current electrical networks, with, for example, a voltage between 90V and 300V, a current between 1mA and 2A, a frequency below 100Hz, for example 50Hz or 60Hz, etc. Complementarily or alternatively, predetermined characteristics associated with direct current (i.e., zero-frequency) power supply sources can also be selected to define certain input electrical signals that can also be used within the scope of this technique, with, for example, a voltage selected from 3V, 5V, 12V, 24V, or 48V.

[0054] According to a particular feature, the input electrical signal can also be formed, alternatively, from a succession of particular predefined signals, each having its own predetermined characteristics (in voltage, intensity, frequency, etc.), different from one signal to another within this succession.

[0055] In a particular embodiment, the triggering of the transmission of the input electrical signal SEE on the LG power supply line is put implemented after the detection, in an optional step 20, of a change in the power supply source, i.e., a switchover of the power supply to all electrical equipment powered via the LG power line from a previous power supply source to a new power supply source. For illustrative purposes only and not as a limitation, using the example of an electrical network such as the one shown in relation to [Fig. 1], step 21, which transmits the input electrical signal SEE, is implemented following the detection of a power outage to the RES network via the main power supply source SRC1 (in this example, high power) and a takeover of the RES network power supply by the backup power supply source SRC2 (in this example, low power).In such a situation, it is then the SRC2 power supply source, the new functional power supply source for the RES network, that is called upon to emit the SEE input electrical signal in step 21.

[0056] In a step 22, a response to the input electrical signal SEE is obtained at the level of the power supply line LG. Such a response is that of the set of electrical equipment (EE1, EE2, EE3) supplied via the power supply line LG, and can be considered representative - possibly after the implementation of a predefined processing of said response, including for example at least one operation among an analog-to-digital conversion of the response, a filtering of the response and / or a normalization of the response according to predefined normalization criteria - of an electronic (or electromagnetic) signature associated with this set of electrical equipment, since it is directly linked to the technical characteristics of the electrical equipment which composes it.This signature is a piece of information that can be described as composite, as it results from a combination of electronic signatures of the electrical equipment in the system (an electronic signature of a piece of equipment can, for example, be extracted from the composite information using signal processing techniques such as demodulation, filtering, etc.). Such electronic signatures may have been previously generated in relation to the input electrical signal used, and are available, for example, in product databases where they are associated with the specific input signal used to generate them, as well as possibly other information relating to the context in which they were generated (e.g., generation conditions, location, company that performed the generation, date of generation, specifications of the electrical network used for generation, etc.).Such information associated with an electronic signature may notably take the form of metadata associated with a file representing said signature (on a model which can be compared, for example, to the EXIF ​​data often associated). to image files), such a file being, for example, stored in a product data structure, linked to the product datasheet of the electrical equipment in question. The response obtained on the LG power supply line corresponds, for example, to a signal observed on this LG power supply line for a predetermined duration, representative of a discharge response of the electronic components (typically resistive and / or inductive and / or capacitive components) of the set of electrical equipment (E1, E2, E3) after being subjected to the SEE input electrical signal. Such a signal is obtained, for example, by means of one or more measuring devices integrated into or capable of communicating with the DISP electronic device implementing the identification method according to this technique.Depending on a particular characteristic, for example to ensure that the response signal obtained on the power supply line is meaningful (especially in the presence of high-power electrical equipment on this line, which may be less responsive), the input electrical signal can be emitted repeatedly, possibly with increasing emission durations. The duration of the response observation period is then also adjusted accordingly.

[0057] In step 23, the DISP electronic device identifies, from the composite information obtained in step 22, at least one electrical device from the set of electrical devices supplied by the power line LG. More specifically, the composite information obtained in response to the input electrical signal is, for example, firstly, as part of a rapid analysis, compared with reference electronic signature records stored in a product database. Such an initial approach is relevant for identifying, for example, a single electrical device connected to a power line (the set of electrical devices then comprising only one device).Alternatively or complementarily, a more in-depth analysis is implemented by providing composite information as input data to at least one electrical equipment identification model previously trained for this purpose. Such a second approach is particularly relevant when a plurality (i.e., two or more) of electrical equipment is connected to the same power supply line (the set of electrical equipment then comprising several devices).

[0058] Such a model, which can be local or remote, is based, for example, on the implementation of multilayer neural networks and the application of deep learning and artificial intelligence techniques. According to a particular characteristic, this model has been trained beforehand, based on several training datasets (typically a large number, e.g., hundreds or thousands of training datasets) associating identifiers of types of electrical equipment and corresponding electronic signatures for a large number of devices. Thus, machine learning algorithms are trained to build one or more models capable of identifying and / or classifying electrical equipment, based on an electronic signature provided as input to the model. The training data for a model, fed during the learning phase, can include associations between an electronic signature and a single piece of electrical equipment (the signature then corresponding, for example, to what can be considered a reference signature for the equipment in question), or between an electronic signature and a combination of electrical equipment (i.e., a plurality of devices) when such a signature has previously been determined in relation to a set of several known electrical devices powered via the same power line.These associations injected during the learning phase can include the injection of electronic signatures associated with electrical equipment exhibiting normal or nominal operation (i.e., "reference" electronic signatures associated with correct, expected operation without apparent equipment malfunction), but also the injection of electronic signatures associated with electrical equipment exhibiting previously observed malfunctions or aging (for example, discovered during the lifecycle of the same series of equipment), or even simulated using digital models of the equipment in question (for example, using modified equivalent circuits to simulate malfunctions due to aging or differences in the quality of the constituent components, e.g.the effects of a drop in the Zener voltage associated with a Zener diode, a decrease in the capacitance of the circuit's capacitors, an increase in the leakage currents of these capacitors, wear on the printed circuit board traces, a progressive loss of shielding effectiveness on certain parts of the circuit, dust, humidity, etc.). It is thus possible to teach the model to more easily identify or classify equipment exhibiting certain known defects, or even to determine the obsolescence or inoperativeness of the equipment based on different signatures. Depending on a particular characteristic, the model according to this technique may, in particular, include or be associated with a large language model (or LLM). Model") previously configured and trained to represent electronic signatures as vectors or sequences of integration vectors, thus enabling the identification of electrical equipment by implementing vector search techniques.

[0059] The identification implemented in step 23 delivers, for example, one or more identifiers (for example, a "category-brand-model" triplet, or any other data). of a nature to be able to unambiguously identify a device) associated with the electrical equipment recognized within said set.

[0060] In step 24, based for example on such identifiers serving as identification keys, additional information associated with the identified electrical equipment is obtained within at least one dedicated data structure. Such a data structure may, for example, take the form of a product database of the EPREL (European Product Registry for Energy Labelling) or DPP (Digital Product Passport) type, which bring together, within a regulatory framework, a large amount of detailed information relating to numerous products in public databases.Obtaining this information through the DISP electronic device can, for example, be based on an automatic exchange of requests and responses with such data structures, via a communication network to which these two entities are connected, and according to a format defined within the framework of at least one application programming interface (or API, for "Application Programming Interface") exposed by these data structures.

[0061] According to a particular characteristic, this additional information includes, for example, data representative of a type of identified electrical equipment (e.g., "identified: kettle", "identified: home gateway or box", "identified: refrigerator"), or data representative of the electrical consumption of said electrical equipment.

[0062] Based on such additional information, a power management policy for electrical equipment is determined in step 25, in a particular embodiment of this technique. In the context of this technique, a "power management policy" means a set of instructions and / or recommendations defining, for example, for each piece of electrical equipment identified in step 23, whether the power supply to the equipment in question should be maintained by leaving it powered on, or whether, on the contrary, the equipment should be switched off or put into standby mode. This policy is determined, for example, on the basis of a set of rules previously defined and stored in a memory of the electronic identification device DISP.These rules define, for example, the conditions under which the power supply to certain electrical equipment should be prioritized over other equipment, based, for instance, on lists of electrical equipment ranked by priority, possibly according to different scenarios. The determination of the power supply management policy also takes into account metrics associated with an observed current state of the network. (available power, instantaneous consumption, etc.), including characteristics associated with the current power supply source of the network (for example, whether the currently available and functional power supply source is low or high power).

[0063] The power supply management policy thus defined is then, according to different alternative or complementary particular embodiments, used to automatically carry out power supply control operations for electrical equipment and / or communicated to a user in order to recommend actions to be implemented or to inform them of actions already implemented automatically at the initiative of the DISP electronic device.

[0064] To this end, at least one message representative of the power supply management policy is emitted by the DISP electronic device, in a step 26.

[0065] In a particular embodiment, such a message takes, for example, the form of a visual and / or audible feedback, intended for a user, of one or more instructions or recommendations for operations to be carried out to implement the determined power management policy. Such feedback may, for example, take the form of a visual message displayed on a screen of a device and / or an audible message emitted by at least one loudspeaker of that device, the device being, for example, the DISP electronic identification device itself, or any other third-party device capable of communicating with the DISP electronic identification device (via a wired or wireless interface) and, in particular, receiving instructions for message feedback.Such a third-party device could, for example, be a communication terminal such as a smartphone, tablet, or computer, on which a dedicated application is installed. The messages thus displayed advise the user, for example, to unplug, switch off, or put into standby mode at least one of the electrical devices identified in step 23, according to the power management policy determined in step 25, in order to restore or maintain the nominal operation of another electrical device also identified in step 23, considered to have priority.

[0066] Complementarily or alternatively, step 26, which involves sending at least one message representative of the power management policy, includes sending at least one power control request to at least one electrical device from among all the electrical devices identified in step 23 (where such electrical devices include interfaces for controlling their power supply). Such requests may, for example, include requests to switch off or put a device into standby mode (for example, a device whose operation is considered non-priority or disruptive), or the switching on or waking from standby of a device (for example, for a device whose continued operation is considered important in a particular context). Thus, according to this particular embodiment, the power management policy can be applied automatically, without requiring manual intervention from a user.

[0067] In another aspect, the proposed technique also relates to an electronic device for identifying at least one electrical device among a set of electrical devices powered by a power supply via the same power line. Such an electronic device is capable of carrying out the method described above in any of its embodiments. More particularly, such a device according to the present technique comprises, in a particular embodiment:

[0068] - means for triggering the emission of at least one electrical signal input of predetermined characteristics by a power supply source on the power supply line of said set of electrical equipment;

[0069] - means of obtaining, at the level of said power supply line, a response of said set of electrical equipment to said electrical input signal, delivering composite information representative of an electronic signature associated with said set of electrical equipment;

[0070] - means of identification, based on said electronic signature, by a model identification of electrical equipment, of at least one electrical piece of equipment from said assembly.

[0071] Figure 3 schematically and in a simplified manner represents the structure of such an electronic device DISP in a particular embodiment. Such a DISP is, for example, connected to or directly integrated into the connection system of an electrical network (for example, the RAC connection system of the RES network illustrated in Figure 1). The DISP according to the proposed technique comprises, for example, a memory 31 consisting of a buffer memory M, a processing unit 32, equipped, for example, with a qP processor, and controlled by the computer program Pg 33, implementing steps of the method for identifying at least one electrical device according to at least one embodiment of the invention. At initialization, the code instructions of the computer program 33 are loaded into the buffer memory before being executed by the processor of the processing unit 32.The processing unit 32 receives as input E, for example, data representative of an instruction to trigger an emission, by an electrical power source, of at least one electrical input signal of predetermined characteristics on a power line. electrical equipment. The processor of the processing unit 32 then performs the steps described above in the identification process, according to the instructions of the computer program 33, to deliver at least one identification piece of information for at least one piece of electrical equipment in said electrical equipment. To this end, the electronic device also includes, in a particular embodiment, at least one communication interface enabling it to exchange messages with other devices.The electronic device includes, for example, at least one Ethernet, WiFi, 3G, 4G, 5G network interface, and / or at least one human-machine interface, and / or at least one wired interface, enabling it, for example, to receive and transmit data to and from other equipment to which it is connected (possibly via an Internet-type communication network) and / or human operators.Such communication interfaces make it possible, for example, to obtain the triggering instructions for the input electrical signal from an electrical power source, to obtain a response from electrical equipment to this input electrical signal from at least one measuring device, to communicate to a remote database a request to obtain at least one additional piece of information associated with an identified electrical equipment, to communicate with various electrical equipment in order to transmit instructions to them, for example, to switch off, to standby, to switch on or to wake up from standby, etc.In a particular embodiment, the number of communication interfaces integrated into the electronic device is limited, as the method according to this technique allows for the identification of electrical equipment (and the detection, where applicable, of any faults, malfunctions, or aging of the identified devices) in a purely local manner. The identification model, possibly associated with a product database, is thus implemented, for example, within the electronic device itself, locally. In such a particular embodiment, the electronic device does not need to have communication interfaces with remote equipment, such as Ethernet, Wi-Fi, 3G, 4G, 5G network interfaces, etc., as the method according to this technique can be implemented with minimal connectivity.
