Description

Title of the invention: REMOTE CONTROL OF THE POWER SUPPLY OF A HETEROGENEOUS PARK OF ELECTRICAL APPLIANCES Technical field

[0001] This disclosure relates to the field of digital display devices. More specifically, it relates to the field of monitoring and controlling the power consumption of display devices. Previous technique

[0002] Display devices are devices for disseminating visual content. Such devices may include, in particular, street furniture designed for displaying advertisements. The content may, for example, include advertisements, but also information or awareness campaigns. Such devices may, for example, include backlit paper display devices, e-paper display devices, or digital display devices, for example, based on LCD screens.

[0003] Display devices may, for example, take the form of large glass boxes placed in public spaces, for example in metro stations, on building facades or integrated into passenger shelters.

[0004] Display devices are particularly useful for disseminating content campaigns on a large scale, for example, advertising or awareness campaigns. Modern display devices are generally connected to the public lighting electrical infrastructure of urban areas.

[0005] While digital display devices provide a particularly attractive solution for massively disseminating content, the power consumption of digital display devices can prove to be significant when a large fleet of display devices is deployed.

[0006] With a view to reducing the environmental footprint and operating costs of display devices, a reduction in their electricity consumption is desired. This reduction in consumption may also respond to rapid legislative changes that, for example, impose switching-off times for display lighting (e.g., a ban on nighttime displays, and / or in the event of an overload of electricity consumption on the local or national electricity distribution network, etc.). Such general changes may also be combined with local restrictions, for example, at the city level.

[0007] It is therefore difficult to deploy or update a fleet of display devices with controllable power consumption that can adapt to various future and as yet unknown legislative changes. This is all the more true given that such changes must be anticipated within an already deployed and heterogeneous fleet, in terms of location, models used, power supply types, communication methods, etc.

[0008] There is therefore a need for a solution to reduce the consumption of display devices that can adapt to different legislative developments, including local ones, and to adapt to a heterogeneous stock of display devices. Summary

[0009] This disclosure improves the situation.

[0010] A device for controlling the power consumption of a display device is proposed, comprising: at least one current probe configured to measure the power consumption of said display device; a communication module capable of receiving control instructions from at least one server; a battery; at least one module for modulating the power consumption of said display device.

[0011] The term "modulation of the power consumption of said display device" means a modification of the device's power consumption via a control of the display device's power supply, with the aim of reducing the device's power consumption. Modulation of the display device may, in particular, consist of cutting off the power supply to all or part of the display device, or varying the brightness of the illumination by pulse-width modulation.

[0012] The control device therefore allows for continuous monitoring of the display device's power supply, thereby reducing the display device's power consumption and enabling continuous adaptation to energy consumption reduction targets or regulatory changes related to power consumption. Furthermore, the presence of a battery in the control device allows the device to remain permanently powered, thus adapting to different types of power supply, including intermittent power supplies such as street lighting.

[0013] According to another aspect, a power control system for a plurality of display devices is proposed, comprising: a plurality of control devices as defined herein; at least one server connected to said plurality of control devices and configured to send control instructions to said plurality of control devices.

[0014] Such a system allows remote control by the server of multiple control devices, and therefore real-time control of the display devices without the need for local intervention or modification of the devices. A potentially heterogeneous set of display devices can thus be controlled in real time, for example, to adapt to regulatory changes or new objectives for reducing the power consumption of the display devices.

[0015] The features described in the following paragraphs may optionally be implemented independently of each other or in combination with each other:

[0016] The device includes at least three current probes.

[0017] For example, the device may include an input for a current probe whose range can be set within the device for a single-phase electrical infrastructure, or two, three, or even more than three current probes. For example, an adapter card may allow the connection of up to three current probes for two-phase or three-phase electrical infrastructures.

[0018] The use of at least three current probes allows interfacing with different types of networks, whether single-phase, two-phase, or three-phase. Thus, a single housing model can be deployed to manage the power supply of display devices or street furniture on different types of networks with infrastructures having different numbers of phases.

[0019] The gauge of at least one probe is adapted to the maximum electrical intensity that can be received by the display device.

[0020] For example, it may be known that a device located at a given location will receive an electrical current of a given maximum intensity (e.g., 5 amperes, 25 amperes, etc.). The size of the electrical probe(s) can therefore be adapted to this maximum intensity, so that it is the smallest available size that allows the device to measure the maximum intensity that can be received. This allows the device to adapt to any electrical distribution infrastructure, and in particular to low- or high-current infrastructures, while limiting the size of the probes.

[0021] The communication module is also capable of transmitting electrical consumption measurements of the display device to at least one server.

[0022] This allows for real-time control of commands and shutdowns, as well as real-time traceability of consumption, and enables the triggering of energy-saving measures. Furthermore, a faulty, energy-intensive component can be detected and isolated from the system by controlling the relays.

[0023] The communication module is a multiband modem.

[0024] The use of a multiband modem therefore makes it possible to adapt to different types of communication networks, particularly cellular networks, worldwide. The same model of device can thus be deployed in different countries while still being able to communicate with servers.

[0025] The controlled device supports a power supply range from 4.5VDC to 30VDC for a nominal voltage of 24VDC.

[0026] The term "VDC" (for "Volt Directional Current") refers to a direct current voltage, measured in volts.

[0027] This wide supply range makes the control device compatible with different types of existing power supplies, as well as variable voltage generators.

[0028] At least one power supply modulation module for said display device includes a power supply cut-off module for said display device

[0029] This makes it possible to respond to instructions for complete suppression of electricity demand, and to achieve significant savings in electricity consumption.

[0030] At least one power consumption modulation module of said display device includes a pulse width modulation module for the luminous intensity of said display device.

[0031] The term "modulation of the luminous intensity of said display device" means the definition, within an permissible range of values, of a luminous intensity level applied to the device overall. This luminous intensity may, for example, be a backlight intensity, such as the backlight intensity of a paper, e-paper, or digital display (e.g., LCD / LED backlight).

[0032] Pulse Width Modulation (PWM) is a technique used to control the amount of power consumed by an electronic device, notably by varying the rate by the width of the pulses sent to the device. This technique allows for precise control of the power consumed by the device.

[0033] The pulse-width modulation module for the light intensity supplied to the display device thus allows for fine-tuning the light intensity and the power consumed by the display device, for example, the backlight intensity. Since this intensity has a significant impact on the power consumption of the display device, the use of a pulse-width modulation module for the light intensity of said display device allows for fine and efficient modulation of the device's power consumption.

[0034] At least one electrical consumption modulation module of said display device includes an activation and deactivation module for at least one actuator of said display device.

[0035] By "an actuator of said display device" is meant an element capable of setting in motion all or part of the display device. An actuator may, for example, be a motor capable of imparting motion to a part of the display device. For example, in the case of display devices for backlit paper advertisements, an actuator may be a motor capable of rotating rollers that scroll the advertisements. For example, display devices in the form of "Morris columns" in which backlit paper advertisements scroll include motors for scrolling the paper rollers displaying the advertisements.

[0036] By "an activation and deactivation module for at least one actuator of said display device," we mean a module capable of activating or deactivating the actuator in order to start or stop the movement imparted by the actuator. Activation or deactivation of the actuator can be achieved, for example, by enabling or cutting off the power supply to the actuator, or by sending a start or stop command to the actuator. For example, the activation and deactivation module for at least one actuator of said display device can be a start or stop module for one or more motors of the display device, and can, for example, enable the scrolling of paper advertisements to start or stop.

[0037] The actuators are likely to consume a significant amount of electricity. Activating or deactivating the actuators therefore allows the energy consumed by the display device to be modulated.

[0038] The device includes a computing unit configured to control at least one power consumption modulation module of said display device according to control instructions received from the server.

[0039] The term "computing unit" refers to an electronic component capable of performing computer calculations to carry out a specific function. A computing unit can be any type of processor or electronic component capable of performing numerical calculations. For example, a computing unit can be an integrated circuit, an ASIC (Application-Specific Integrated Circuit), a microcontroller, a microprocessor, a DSP (Digital Signal Processor), a processor, or a GPU (Graphics Processing Unit). A computing unit according to the invention is not limited to a particular type of computing architecture. For example, a processor can implement a Harvard or Von Neumann architecture.

[0040] This makes it possible to effectively control the electrical power consumed by the display device. Brief description of the drawings

[0041] Other features, details and advantages will become apparent from reading the detailed description below and from analyzing the accompanying drawings, in which: Fig. 1

[0042] [Fig.1] shows a control system for a plurality of display devices according to one embodiment. Fig. 2

[0043] [Fig.2] shows a power supply control device for a display device in one embodiment. Description of the implementation methods

[0044] Reference is now made to [Fig.1].

[0045] Fig. 1 represents a Sysl control system for a plurality of display devices according to one embodiment.

[0046] System 1 is intended for the remote control of a plurality of display devices such as an Affl device by at least one remote Servi server. The display devices may include, in particular, backlit paper advertising displays, but also e-paper advertising displays, electronic displays, or digital displays such as LCD displays.

[0047] In Figure 1, for readability, a single Affl display device is shown. However, in general, the Sysl system can be used for the remote control of the power supply to a plurality of separate display devices. According to different embodiments of the invention, the types of display devices controlled can be homogeneous (for example, only backlit paper advertising display devices or only digital display devices are controlled), or heterogeneous (in which case different types of display devices can be controlled simultaneously, for example, both backlit paper and digital display devices).

[0048] Each display device is equipped with a device for controlling the power consumption of the display device. For example, the Affl display device is equipped with the Ctrl power consumption control device for the Affl display device. In general, the Ctrl power consumption control device can control the power consumption of the Affl display device in various ways: - By turning the power supply on or off; - By modulating the light intensity of the device, that is, the light intensity displayed by the display device, for example, through pulse-width modulation. Depending on the type of display device, the modulation of the light intensity can thus be, for example: • a modulation of the backlight intensity of paper advertisements; • a modulation of the light intensity of e-paper or digital ink backlighting; • a modulation of the backlight intensity of a digital screen such as an LCD screen; • a modulation of the overall light intensity of content to be displayed on a digital screen; - by activating or deactivating actuators of the display device, such as, for example, motors that scroll paper advertisements; - etc.

[0049] The power consumption modulation module may thus comprise one or more power consumption modulation modules, each corresponding to at least one type of power consumption modulation. When several types of power consumption modulation are used, they may be used sequentially or simultaneously. For example, the power consumption of the display device may be reduced by decreasing the light intensity and simultaneously switching off a motor, and, if power consumption needs to be reduced even further, the power supply to the display device may be switched off.

[0050] These examples are provided, however, as non-limiting examples only, and any action enabling the modulation of the power consumption of the display device can more generally be used.

[0051] The Ctrl control device can, for example, be integrated or embedded in the Affl display device, or disposed outside the Affl display device, for example placed on the Affl display device.

[0052] The Affl display device can be connected to the Servi server via a remote connection. For example, the Affl display device can support connections such as 3G, 4G, 5G, or more generally any connection usable at the location of the Affl display device.

[0053] This allows the Servi server to transmit control instructions to the Ctrl control device. The server's instructions may, for example, consist of instantaneous control instructions (e.g., activation / deactivation). (power supply, light intensity modulation, activation / deactivation of actuators, etc.), but also the sending of control programs. Control programs can, for example, consist of the application of programs indicating the control instructions to be applied for different days and / or times (e.g., power supply activation times, light intensity to be applied according to the day / time, etc.).

[0054] The Servi server can thus control the Affl display device centrally, independently of the characteristics of the Affl display device. The Servi server can also update the control instructions as needed, for example in the event of new objectives for reducing the power consumption of display devices, or regulatory changes concerning displays, and this without the need for modification of the display devices or the need for local intervention.

[0055] The connection between the Ctrl device and the Servi server can also allow the Ctrl control device to transmit data to the server regarding the electrical consumption of the Affl display device.

[0056] For example, electricity consumption information can be transmitted in real time to at least one Servi server via Servi requests or automated Ctrl transmissions. This allows for real-time control of commands and outages, as well as real-time consumption tracking, and enables the triggering of energy-saving measures. Alternatively, to limit energy consumption and the data allowance, electricity consumption information transmissions can be programmed to be sent only by sampling at predefined intervals or intervals configured by Servi. Furthermore, a faulty, energy-intensive component can be detected and isolated from the electrical network by controlling the relays.

[0057] Such transmission of consumption information from the Ctrl control devices to at least one Servi server allows for the monitoring and optimization of the display devices' energy consumption, enabling intelligent and real-time management of the distributed energy, either for a single display device or a group of displays. If at least one server detects an anomaly, a command to shut down the display device can be sent, and an investigation and repair can be carried out within a short timeframe. The energy consumption of one or more display devices can be visualized via a web interface, allowing one or more maintenance teams from different agencies or regions to monitor the displays by list or map within a limited area of ​​their intervention zone or across the entire display fleet.

[0058] The Sysl system may also include at least one UDevl user device capable of connecting to the Ctrl control device.

[0059] The UDevl user device can, for example, be a device (smartphone, tablet, etc.) belonging to a field agent that can connect via a serial link, a connected application, an internet link, or any other link applicable to the Ctrl device in order to configure the Ctrl device and control and facilitate interventions, particularly maintenance.

[0060] The maintenance technician can thus configure the Ctrl control device via the UDevl user device, and in particular an Ecrl control screen. This provides an additional control method, facilitates maintenance operations, and allows for fine-tuning of energy-saving settings by a technician physically present on site.

[0061] Reference is now made to [Fig.2].

[0062] Fig. 2 represents a Ctrl device for controlling the power supply of a display device in one embodiment.

[0063] As discussed with reference to [Fig. 1], the Ctrl control device can be integrated into the Affl display device, for example, embedded within the Affl display device. The Ctrl control device can also be an external module, for example, attached to the Affl display device. Generally, the Ctrl control device can interface between the power supply and the Affl display device in order to measure the power consumption of the Affl display device and control its power supply.

[0064] The Ctrl device includes at least one current probe Snd2 configured to measure the power consumption of said display device. This at least one current probe Snd2 can, for example, measure in real time the power consumed by the display device Affl, the current intensity supplied to the display device Affl, the RMS current supplied to the display device Affl, or more generally any representative measurement of the power consumption of the display device Affl.

[0065] According to various embodiments of the invention, the Ctrl control device may comprise a single current probe for measuring the power consumed by a single-phase supply, or two, three, or even more than three current probes for calculating the power consumed in single-phase, two-phase, or three-phase modes. The current probes may correspond to different ratings, for example, from 5 Amp to 25 Amp. Preferably, the probe rating may be selected based on the maximum current that can be supplied to the display device, for example, by selecting probes of 25 amps for high-power equipment, or 5 amps for low-power equipment. Thus, using one, two, or three probes to cover single-phase or three-phase currents, and of different ratings, makes it possible to cover all international electrical uses and configurations; regardless of the voltage, frequency, or power to be monitored in the user country.

[0066] In particular, three current probes, combined within a three-phase probe, allow the measurement of the effective currents recorded on each phase. Such a three-phase probe can thus support two-phase and three-phase systems with or without a neutral. Three-phase electrical topologies relating to a star connection at 230 Vac, or a delta connection at 400 Vac for Europe, are therefore supported. This three-phase probe thus makes it possible to cover all types of multi-phase power electrical topologies existing in all countries.

[0067] Thus, the use of at least three probes of suitable sizes allows the unit to interface with all types of electrical networks in different countries, whether single-phase, two-phase, or three-phase, and with varying current intensities. Therefore, a single unit model can be deployed to manage the power supply of display devices or street furniture worldwide.

[0068] The Ctrl device further includes a Comm2 communication module enabling communication with at least one server such as the Servi server.

[0069] The Comm2 communication module allows, in particular, the reception of control instructions from at least one server. The Comm2 communication module can also receive configuration updates, as well as other information such as, for example, software updates.

[0070] Instructions can be, for example, instant instructions or programs. Different types of possible instructions have already been discussed with reference to [Fig. 1].

[0071] The communication module Comm2 can also, in a set of embodiments of the invention, transmit to at least one server power consumption measurements of the display device, in particular measurements taken by at least one probe Snd2. The communication module Comm2 can also send back to the server other information such as the status of the controlled inputs and actuators.

[0072] The communication module can be a multiband modem, in order to cover different bands of global telecom operators by changing the modem's transmission bands. In particular, the modem can cover 2G / 3G / 4G / 5G / 6G bands by sending and receiving mobile data and / or by sending and receiving SMS messages.

[0073] The use of a multiband modem therefore makes it possible to adapt to different types of communication networks, particularly cellular networks, worldwide. The same model of device can thus be deployed in different countries while still being able to communicate with servers.

[0074] The Ctrl control device may also include a power supply module Alim2. The power supply module Alim2 is capable of receiving a power supply, for example from a mains power supply or from a power supply for the display device Affl, such as a solar panel. For this purpose, the power supply module Alim2 may be capable of receiving direct or alternating current, according to different types of power supply (single-phase / two-phase / three-phase, 230Vac / 110Vac, according to different frequencies, etc.).

[0075] The Alim2 power supply module can also be configured to provide the Ctrl control device with power according to the Ctrl control device's power supply mode. In one embodiment, the Ctrl control device is characterized by its low power consumption and its ability to support a very wide operating voltage range from 4.5Vdc to 30Vdc, making it compatible with various existing power supplies in furniture and eliminating the need for additional regulated power supplies. Furthermore, this wide operating voltage range allows its use when connected to variable or unstable voltage generators such as batteries, solar panels, or small wind turbines. - The Ctrl control device can also optionally include a Batt2 battery. The battery provides power when the power supply fails. A battery is particularly useful when the Affl display device is connected to a public lighting power supply network that is intended to be switched off during the day; - when the Affl display device is connected to an electricity supply network, but the power supply is likely to be interrupted. This is the case, for example, when the electricity network is temporarily faulty, or when there is a power outage at the network level, for example during load shedding operations or if a power supply at certain times is no longer guaranteed; - when the Affl display device is powered by an intermittent power source, for example one or more solar panels;

[0076] The Batt2 battery can thus store electrical energy when it is supplied to the Affl display device, and release it when it is no longer supplied. The power supply The electrical power supply to the Ctrl control device is therefore guaranteed at all times. This ensures, for example, that instructions sent by the server are not missed.

[0077] The presence of the Batt2 battery therefore ensures the continuity of the power supply to the Ctrl control module regardless of the Affl display device, and in particular regardless of the power source of the Affl display device. Thus, the same control module model can be deployed in different countries and contexts (display device connected to the electrical grid or powered separately, etc.).

[0078] As an example, the Batt2 battery can be a 24Wh battery module integrating BMS and charger for a battery life of more than 12 hours.

[0079] The Ctrl control device also includes at least one Mod2 module for modulating the power supply of said display device.

[0080] At least one Mod2 power supply modulation module can modify, or modulate, the power consumption of the display device, in particular to respond to control instructions received by at least one server.

[0081] To this end, the Ctrl control device may include at least one sub-module allowing, for example: - Cut off the power supply to the display device, for example via one or two outputs to relays; - modulate the light intensity of the device via PWM modulation; - activate or deactivate one or more actuators of the device.

[0082] Thus, the Ctrl control device is capable of measuring the power consumed by the Affl display device, receiving control instructions from at least one server, and adapting the power consumption of the Affl display device according to the received control instructions. Furthermore, the presence of the battery allows the Ctrl control device to be continuously powered, particularly in the event of intermittent power supply or a power outage to the Affl display device. The Ctrl control device is therefore continuously capable of receiving control instructions from at least one server and controlling the power supply to at least one display device.

[0083] The Ctrl control device therefore allows permanent control of the power consumption of the Affl display device, thus making it possible to reduce the power consumption of the Affl display device, and to adapt continuously to objectives of reducing power consumption or regulatory changes relating to power consumption.

[0084] Furthermore, in certain embodiments the Ctrl control device is adaptable to many types of power supplies and communication networks. Thus, a single control device model can be deployed internationally. in many different countries, regardless of the types of power supplies or communication networks used in those countries. The Ctrl communication module therefore enables the rapid and flexible deployment of energy-saving solutions.

[0085] The modulation of the electrical supply can generally be done via the control of various relays, lights and actuators of the Ctrl control device.

[0086] In a set of embodiments of the invention, at least one Mod2 module for modulating the electrical consumption of said display device Affl includes a Coup2 cutoff module for the power supply of said display device Affl.

[0087] The Coup2 cutoff module allows the power supply to be cut off to certain elements of the Affl display device, or even to the entire device. This makes it possible to reduce the power consumption of the Affl display device to zero, for example, to comply with a command to completely eliminate the power demand of the Affl display device. Using a cutoff therefore allows for significant energy savings. The cutoff can, for example, be achieved by switching off power components via relays (or active electronic components).

[0088] In a set of embodiments of the invention, at least one Mod2 modulation module of the electrical consumption of said display device includes a PWM2 pulse width modulation module of the luminous intensity of said display device.

[0089] The PWM2 pulse width modulation module of the display light intensity therefore allows the power consumed by the display device to be finely varied by varying the rate and width of the pulses supplied.

[0090] The PWM2 pulse-width modulation module thus enables more precise, rather than binary (power on / off) control of the lighting. This is particularly useful for display devices using backlighting that allows for illumination at different power levels. For example, this allows the lighting power to be gradually reduced by dimming. This device maintains the functional performance of the devices while minimizing energy consumption. Such devices may include, for example, backlit paper advertising displays, digital ink displays, or backlit digital displays such as LCD displays.

[0091] The Mod2 modulation module for the power consumption of said display device may also include other types of modulation modules not shown in [Fig. 2], such as, for example, an activation and deactivation module for at least one actuator of said display device. An activation and deactivation module for at least one actuator of said display device allows for the activation or disable at least one actuator of the display device, for example start or stop a motor used to scroll paper advertisements.

[0092] In a set of embodiments of the invention, the Ctrl control device includes a Calc2 computing unit configured to control at least one Mod2 modulation module of the electrical consumption of said display device according to the control instructions received from the server.

[0093] The Calc2 calculation unit can thus determine, based on the instructions received, the command to be transmitted to at least one Mod2 modulation module to achieve the desired modulation of electrical consumption.

[0094] The operations performed by the Calc2 calculation unit can thus, for example, correspond to: - the application of instantaneous control instructions received from at least one Servi server. For example, at least one Servi server can be configured to send instructions to activate / deactivate the power supply, to provide a given power via pulse width modulation, etc., at the time they need to be carried out; - the application of instructions defining a program to be applied. For example, instructions received from at least one Servi server. For example, instructions can define time ranges for power supply / power cut-off, power to be supplied according to time ranges and / or days, etc.; - etc.

[0095] The Calc2 calculation unit can also access measurements taken by at least one Snd2 probe and apply control instructions depending on the power consumed by the Affl display device. For example, the Calc2 calculation unit can apply: - Instructions to limit the instantaneous power consumed by the Affl display device. For example, as soon as the instantaneous power supplied, measured by at least one Snd2 probe, exceeds a threshold, the power supplied can be limited by pulse-width modulation, or even the power supply can be cut off. The threshold can thus be defined and updated by receiving instructions from at least one server. The threshold can be constant, or variable, for example depending on the time of day; - Instructions to limit the total power consumed by the Affl display device over a given period, for example, limiting the total power consumed by the Affl display device hourly, daily, etc. In this case, the power supply to the Affl display device can simply be cut off when a power threshold is reached. The total power consumed over a given period is exceeded. Alternatively, the power supplied can be reduced when the total power consumed approaches or exceeds the threshold. Here too, the threshold can be defined and updated by receiving instructions from at least one server. The threshold can be constant or variable, for example, depending on the time of day.

[0096] In general, at least one server can therefore transmit instructions to limit the power consumption of the Affl display device. Of course, generally, at least one Servi server will not control a single device, but a large number of devices. At least one server has considerable flexibility to modify the way the power supply to the display devices is modulated as needed. In particular, at least one server can transmit control instructions in real time to adapt to changes in regulatory constraints and / or to variables evaluated in real time.For example, at least one server can send instructions to reduce electricity consumption in the event of a risk of overconsumption on an electrical grid, if the price of energy exceeds a given threshold, if the carbon intensity of the electricity produced exceeds a given threshold (for example, if high consumption or a shortfall in renewable energy production necessitates the use of fossil fuels for electricity generation), etc. The instructions issued by at least one server can therefore achieve a wide variety of goals, such as, in general, limiting electricity consumption, but also, more specifically, maintaining grid stability, limiting the operating costs of display devices, reducing greenhouse gas emissions, etc.

[0097] As already mentioned, a device such as the Ctrl control device can interface with any type of display device, electrical network, and communication network. A single Ctrl control device model can therefore be deployed in any type of environment and in any country. This allows for the widespread and efficient deployment of solutions for reducing the energy consumption of display devices.

[0098] In a set of embodiments of the invention, the Ctrl control device also includes a local communication port LocCom2.

[0099] The local communication port LocCom2 is a communication port that allows an operator physically present near the Ctrl device to communicate with the control device. It can be a wired connection port (serial port, USB, etc.) or a wireless connection such as a Bluetooth port. This allows an operator with a user device such as the UDEvl device to connect to the device. Ctrl, for example to perform maintenance operations or receive control instructions locally.

[0100] This disclosure is not limited to the examples of devices and systems described above, which are only examples, but encompasses all the variants that a person skilled in the art may consider in the context of the protection sought.
