Description

alert management method via a connected distribution terminal for cleaning and/or disinfectant solution

The technical context of the present invention is that of sanitary devices for use by the public and making it possible to deliver doses of cleaning and/or disinfecting solutions in order to limit the spread of viruses or bacteria in the population. More particularly, the invention relates to an alert management method via such a connected distribution terminal.

State of the prior art

With the emergence of large-scale health crises and the associated risks of pandemics, we have seen the appearance in public spaces of hydroalcoholic gel distribution terminals in order to allow the population to disinfect their hands when moving around the city. 'public space. In addition, many states, many public establishments and many companies have put in place barrier gestures in order to collectively fight against the spread of viruses and their transmission by air or skin from one individual to another. These barrier gestures include the reduction of physical contact and the protection of the respiratory tract.

However, despite all these precautions, the spread of viruses is only partially slowed down, and civil societies face the recurrent emergence of pandemics whose health, economic and social consequences are significant, costly and painful.

In particular, in the event of detection of an infected individual, it is necessary to be able to very quickly identify the other individuals with whom he may have been in contact or even crossed their path. There are currently no technical solutions for establishing such lists, since individuals are free to move around anonymously in public spaces in particular.

In addition to this problem of identification, it is also necessary to be able to warn individuals who have been punctually close to an individual positively diagnosed with contamination.

An object of the invention is to propose a new alert management method in order to respond at least in large part to the above problems and to lead in addition to other advantages.

Another object of the invention is to allow the establishment of contact cases of an individual who has been diagnosed positive for a virus or a contaminant.

Another object of the invention is to facilitate such identification of contact cases within a very short response time.

Another object of the invention is to effectively limit the spread of a contaminant or a virus through individuals.

According to a first aspect of the invention, at least one of the aforementioned objectives is achieved with an alert management method via a terminal for dispensing a cleaning and/or disinfectant solution, the alert method comprising the steps following:

- a pairing step of a portable telecommunications device with the distribution terminal;

- a step of recording identification data relating to the portable telecommunications device;

- a step for activating an alert function;

- an alert step comprising the sending of a message to at least one portable telecommunication device whose identification data has been recorded.

The pairing step allows a portable telecommunications device to reserve the use of the cleaning and/or disinfectant solution distribution terminal. By way of non-limiting example, the pairing step comprises a step of transmitting identification data from the portable telecommunication device to the distribution terminal, a step of receiving the identification data by the distribution, a comparison step during which the identification data is compared with a reference value. If the comparison is valid, that is to say if the identification data conforms to the reference value, then the portable telecommunication device is paired with the distribution terminal and communication is established between the distribution and said portable telecommunication device. If the comparison is invalid, i.e. if the identification data is incompatible – i.e. does not comply – with the reference value, then the portable telecommunication device is not paired with the distribution terminal, and no communication is established between the distribution terminal and the portable telecommunication device.

When the distribution terminal is paired with a portable telecommunications device, then it is possible for the user of the portable telecommunications device to use the distribution terminal, and in particular to receive a dose of cleaning and/or disinfectant solution . In other words, in the case where the distribution terminal is paired with a portable telecommunication device, then the pairing step also includes a step for authorizing use of the terminal, taking the form of an unlocking of the dispensing terminal allowing said dispensing terminal to deliver a dose of cleaning and/or disinfectant solution. Conversely, when the distribution terminal is not paired with a portable telecommunications device, then it is impossible for the user of the portable telecommunications device to use the distribution terminal, and in particular to receive a dose cleaning and/or disinfectant solution.

Following this pairing, the link established between the portable telecommunications device and the distribution terminal is two-way or one-way. In the case of a one-way link, then only the distribution terminal transmits data to the portable telecommunications device; and in the case of a two-way link, the distribution terminal is further configured to receive data transmitted by the telecommunication device. In particular, when a first portable telecommunications device is paired with the distribution terminal, then it is not possible for a second portable telecommunications device to be paired simultaneously with the same distribution terminal.

The identification data of the portable telecommunications device comprises any type of data making it possible to identify and distinguish a first portable telecommunications device from any other portable telecommunications device. By way of non-limiting example, the identification data may comprise an identifier of the portable telecommunication device, the identifier being represented by a series of one or more alphanumeric characters. The series thus formed is unique, each portable telecommunication device being associated with a different series from that of all the other telecommunication devices.

The step of recording the identification data is recorded on an internal memory of the distribution terminal or recorded on a remote network to which the distribution terminal is connected.

In order to establish a one-way or two-way communication with a portable telecommunication device located nearby, the distribution terminal includes a radio frequency communication module.

In the alert management method in accordance with the first aspect of the invention, the distribution terminal communicates with the portable telecommunications device through a Bluetooth link. By Bluetooth link, we understand the establishment of a radio signal at very high frequencies between 2.4 and 2.485 GHz, as defined in the IEEE802.15.1 standard. Optionally, the connection is of the Bluetooth low consumption type (BLE, English acronym meaning Bluetooth Low Energy). This configuration advantageously makes it possible to establish two-way communication over greater distances, typically less than 100m.

Alternatively or additionally, in the alert management method in accordance with the first aspect of the invention, the distribution terminal communicates with the portable telecommunications device through a near-field link. By near-field link, we understand the establishment of a short-range, high-frequency wireless telecommunication – typically equal to 13.56 MHz – as described in the ISO/IEC 14443 standard for NFC technology (English acronym for Near Field Communication). This advantageous configuration makes it possible to establish a more secure link between the distribution terminal and the portable telecommunications device.

By way of non-limiting example, the distribution terminal implemented in the alert management method in accordance with the first aspect of the invention comprises (i) a reservoir for housing the cleaning and/or disinfectant solution, (ii) a system for dispensing a dose of the cleaning and/or disinfectant solution, (iii) a control module making it possible to control the dispensing system, and (iv) a radio frequency communication module making it possible to establish one-way or two-way communication wirelessly between the distribution terminal and a portable telecommunications device.

Preferably, but not limited to, the cleaning and/or disinfectant solution delivered by the dispensing terminal is of the type of a hydroalcoholic solution or a solution containing a soap.

The dispensing system makes it possible to circulate the cleaning and/or disinfectant solution from the reservoir and in order to provide a dose of said solution, by controlling the flow rate of cleaning and/or disinfectant solution.

The radiofrequency communication module is configured to transmit and receive an outgoing or incoming modulated radiocommunication signal, that is to say respectively transmitted by the distribution terminal and in the direction of one or more portable telecommunication devices, or received by the distribution terminal. The radiofrequency communication module thus enables the distribution terminal to transmit or receive digital data exchanged with one or more of the portable telecommunications devices located nearby.

The control module takes the form of one or more electronic cards connected to each other and to the distribution system, the radio frequency communication module and the electrical power source of the distribution terminal. By way of non-limiting examples, the electronic cards forming the control module may include integrated circuits for processing the data exchanged with the radiofrequency communication module and the distribution system. Alternatively or additionally, the electronic cards forming the control module can comprise integrated circuits for controlling the radiofrequency communication module, the distribution system and the electrical power source. The integrated circuits can take the form of one or more controllers and/or one or more microprocessors and/or one or more microcontrollers and/or one or more programmable logic circuits (FPGA, English acronym meaning Field Programmable Gate Array) and/or one or more integrated circuits specific to an application (ASIC, English acronym meaning Application Specific Integrated Circuit).

Additionally, the control module may include and/or be connected to and/or be configured to access a memory configured to store digital data. By access, it is understood that the control module is configured in particular to be able to write and/or read from the memory. The electronic cards forming the control module can comprise any type of memory, such as for example volatile and/or non-volatile and/or cache and/or buffer memory and/or optical memory and/or read-only programmable erasable memory.

The control module and/or the radio frequency communication module make it possible, together or separately, to implement one or the other of the steps of the alert management method in accordance with the first aspect of the invention.

Of course, the invention is not limiting to the type of portable telecommunications device, which can be any connected object comprising wireless telecommunications means that are interactive with other connected objects, and in particular the terminals of distribution. By way of non-limiting examples, such a portable telecommunications device can be a mobile phone, a connected watch or any accessory connected to a mobile phone, a tablet, a laptop computer, etc.

The alert management method in accordance with the first aspect of the invention advantageously comprises at least one of the improvements below, the technical characteristics forming these improvements being able to be taken alone or in combination:

- the identification data recorded during the registration step include the identifier of the portable telecommunications device transmitted during the pairing step;

- the identification data recorded during the registration step includes a telephone number associated with the portable telecommunications device of the user of said portable telecommunications device. This technical data is important in order to be able to trigger a subsequent telephone call and/or the sending of a message. In addition, it makes it possible to geolocate a specific user relative to the distribution terminal with which he has interacted, via his portable telecommunications device;

- the step of recording the identification data includes a step of transmitting the telephone number to the distribution terminal. According to a first variant embodiment, the step of transmitting the telephone number is carried out by direct entry via a user interface of the distribution terminal, such as for example a touch screen housed on said distribution terminal. According to a second variant embodiment, the step of transmitting the telephone number is carried out by wireless transmission between the distribution terminal and the portable telecommunication device, such as for example via the establishment of a bluetooth or NFC communication as previously described;

- the identification data recorded during the registration step includes an electronic mail address associated with the portable telecommunications device of the user of said portable telecommunications device. This technical data is important in order to be able to trigger the sending of an electronic message later. In addition, it makes it possible to geolocate a specific user relative to the distribution terminal with which he has interacted, via his portable telecommunications device;

- the step of recording the identification data includes a step of transmitting the e-mail address to the distribution terminal. According to a first variant embodiment, the step of transmitting the electronic mail address is carried out by direct entry via a user interface of the distribution terminal, such as for example a touch screen housed on said distribution terminal. According to a second variant embodiment, the step of transmitting the electronic messaging address is carried out by wireless transmission between the distribution terminal and the portable telecommunication device, such as for example via the establishment of a communication bluetooth or NFC as described above;

- the identification data recorded during the recording step includes timestamp data. This technical characteristic makes it possible to temporally locate the presence of the user near the distribution terminal. In particular, taken in combination with the identification data previously described, it is thus possible to geolocate the individuals who have used the distribution terminal within any time interval. This clever combination of recorded data allows more efficient data processing and optimal triggering of the alert process and selection of individuals to be notified. To this end, the step of recording the identification data includes a prior step of determining a local time relating to the distribution terminal and/or to the portable telecommunications device. According to a first variant embodiment, the local time is determined by the control module of the distribution terminal, the local time then being recorded with the other identification data. According to a second variant embodiment, the local time is transmitted by the portable telecommunications device during its pairing step with the distribution terminal, for example;

- the alert management method in accordance with the first aspect of the invention comprises a prior step of requesting authorization to record the identification data. The authorization request step takes the form of sending an authorization message for recording identification data and a step of receiving confirmation data that can take at least two distinct states. The stage of sending the authorization request message is carried out by the distribution terminal, via bluetooth or NFC communication for example. The step of receiving the confirmation data includes a step of sending said confirmation data by the portable telecommunication device and a step of receiving said confirmation data by the distribution terminal. Preferably, the reception step is carried out through a Bluetooth or NFC communication protocol as described above. If the confirmation data is of the type of a first state – called positive – then the step of recording the identification data is carried out. If the confirmation data is of the type of a second state – called negative – then the step of recording the identification data is omitted;

– according to a first variant embodiment, the step of recording the identification data is carried out directly on the distribution terminal, the distribution terminal comprising an internal memory in which the identification data is recorded. According to a second variant embodiment, the step of recording the identification data is carried out on a remote server, the distribution terminal comprising means of communication with the remote server. In this case, the means of communication can be of the type of telecommunication means, such as for example a GSM, 3G, 4G, 5G chip, or the means of communication can be of the type of a wired or wireless connection to the server remote, such as for example an ethernet connection, an internet connection or a wifi type connection;

- the step of determining the local time is carried out on the remote server at or near the time when the identification data is recorded on said remote server. By "nearby", it is understood that the determination and the recording of the local time is carried out in a predetermined interval with respect to the moment when the identification data are recorded on the remote server, for example of the order of a few seconds ;

- the step of recording the identification data includes the recording of geolocation data of the distribution terminal having transmitted the identification data. In a non-limiting way, this step is particularly advantageous to carry out in the case where the registration step is carried out on the remote server. Geolocation data means relative or absolute geolocation data. An absolute geolocation coordinate is such as for example a geographical coordinate of the type of a latitude and a longitude, or a GPS coordinate or a triangulation coordinate. Relative geolocation data is data making it possible to locate the distribution terminal relative to a distinct marker whose absolute coordinates are known, the relative data of the distribution terminal being defined relative to said marker;

- according to a first variant embodiment, the step of activating the alert function takes the form of (i) a local configuration of the distribution terminal, that is to say a manual configuration of the distribution terminal, for example via a specific graphic interface displayed on a display screen of the distribution terminal, or (ii) the receipt of a specific activation command on the distribution terminal, via of its means of telecommunication or via its radiofrequency communication module and the establishment of a Bluetooth or NFC communication. In this case, the activation command is interpreted by the distribution terminal control module and allows it to be configured in such a way as to trigger an alert step. In this first variant embodiment, the step of activating the alert function – at the origin of the triggering of the subsequent alert step – is carried out by or on the distribution terminal itself. In this first variant, the activation step is carried out in a delocalized manner, at the level of each distribution terminal, and makes it possible to deploy a network of intelligent distribution terminals and equipped with autonomous functionalities, thus reducing the need for development and network infrastructure to interconnect distribution terminals with a remote server;

- according to a second variant embodiment, the step of activating the alert function is carried out centrally at the level of the remote server to which the distribution terminal is connected. In this case, it is the remote server that activates the alert step. This activation step is carried out centrally, at the level of the remote server, and makes it possible to limit IT developments at the level of the distribution terminal, thus favoring centralized management of a fleet of distribution terminals according to the invention;

- the alert step includes a step for selecting a set of recorded identification data, called a critical set. This step makes it possible to determine which users – through the identification data exchanged with the distribution terminal and their portable telecommunications device – should be notified. In particular, the critical set is determined – for each portable telecommunication device with which the identification data is associated – by a step of comparing at least one of the identification data with a reference value. The reference value is of the type of a critical time, the critical set then being formed by all or part of the identification data corresponding to the portable telecommunications devices whose timestamp data is located close to the critical time . By proximity, it is understood that the corresponding timestamp data is located within a given time interval, for example between a few seconds and 3 hours. The critical time can be determined at the level of the distribution terminal concerned or at the level of the remote server;

- the reference value is of the type of a critical geographical coordinate – relative or absolute – such as for example a GPS coordinate or triangulation data, the critical set then being formed by all or part of the identification data corresponding to the portable telecommunications devices whose geolocation data is located near the critical geographic coordinate. By proximity, it is understood that the corresponding geolocation data is located within a given geographical area, for example included within a circle of a predetermined diameter, for example equal to a few tens of meters . The critical geographical coordinate can be determined at the level of the distribution terminal concerned or at the level of the remote server. Advantageously, the critical geographic coordinate corresponds to geolocation data of a distribution terminal

– according to a first embodiment, the critical set is determined at the level of the distribution terminal. In other words, the step of selecting the set of recorded identification data forming the critical set is performed on the distribution terminal using the identification data recorded on said remote server, or possibly on the distribution terminal, the selection step being implemented by the control module of said distribution terminal. To this end, the distribution terminal comprises on-board telecommunication means as described above and making it possible to communicate with the portable telecommunication devices during the alert stage. Indeed, at the time of the alert, the portable telecommunications devices are probably no longer located in direct proximity to the distribution terminal, rendering the radio frequency communication module inoperative. Therefore, it is necessary to use other communication protocols with portable telecommunications devices, since the blueotooth or NFC protocols can no longer work. This is the role of the means of communication of the distribution terminal: to enable it to communicate over long distances with any portable telecommunications device. By way of example, the on-board telecommunication means of the distribution terminal can be of the type of a GSM chip and/or a wired connection and/or a wireless connection to a remote network making it possible to then communicate to portable telecommunications devices;

- according to a second variant embodiment, the critical set is determined at the level of the remote server. In other words, the step of selecting the set of recorded identification data forming the critical set is performed on the remote server using the identification data recorded on said remote server, or possibly on the distribution terminal;

- the alert management process includes a step of deleting the identification data of the critical assembly. This step makes it possible to better manage the memory zone dedicated to the recording of these identification data, in particular in the case where said identification data are recorded on the distribution terminal. Advantageously, the deletion step is carried out periodically, according to a given reset period. By way of non-limiting example, the reset period is equal to 15 days;

- the alert management process includes an initial step of displaying contextual data on the distribution terminal, the contextual data relating to an establishment located near the distribution terminal. The contextual data is for example of the type of a restaurant menu, comprising the dishes served. More generally, the contextual data is linked to a location of the terminal in a public or private space. According to a first variant embodiment, the contextual data displayed on the distribution terminal is stored in a memory zone of the distribution terminal. According to a second variant embodiment, the contextual data displayed on the distribution terminal is recorded on a remote server and transmitted to the distribution terminal.

According to a second aspect of the invention, a cleaning and/or disinfectant solution distribution network is proposed, the network comprising:

– a plurality of distribution terminals for a dose of cleaning and/or disinfectant solution, each distribution terminal comprising means configured to implement the alert management method in accordance with the first aspect of the invention or according to any of its improvements;

The volume of the tank is preferably between 0.5 liters and 10 liters. Advantageously, the volume of the reservoir is between 1 liter and 5 liters to optimize both the size and the number of doses of cleaning and/or disinfectant solution delivered by the dispensing terminal before filling or replacing the reservoir. The reservoir can be made of any material, in particular plastic or metal. According to a preferred embodiment, the tank forms a container housed inside the terminal and its casing. According to an alternative embodiment, the tank is formed in whole or in part by a part of the casing of the distribution terminal.

The tank is preferably hermetically sealed to limit evaporation of the cleaning and/or disinfectant solution, and to reduce the risk of inflammation. Advantageously, the dispensing terminal includes a device for accessing the reservoir in order to allow it to be filled and/or replaced. According to a first exemplary embodiment, such an access device can take the form of a removable, retractable or pivotally mounted hatch and giving access to the part of the distribution terminal housing the reservoir, in order to be able to extract or insert the reservoir in the casing of the distribution terminal. According to a second exemplary embodiment, such an access device can take the form of a repositionable closure plug – preferably hermetically – and allowing the reservoir to be filled with cleaning and/or disinfectant solution.

The dispensing system makes it possible to circulate the cleaning and/or disinfectant solution from the reservoir in the direction of the dispensing head, while controlling the flow rate of cleaning and/or disinfectant solution. Preferably, in order to limit leaks of cleaning and/or disinfectant solution in the dispensing terminal, the dispensing system is coupled hermetically, in particular at the level of the reservoir and of the dispensing head.

The regulation of the flow of cleaning and/or disinfectant solution circulating in the distribution system is ensured by the pump controlled by the control module of the distribution terminal. The pump is at least configured to make it possible to adjust the flow rate of cleaning and/or disinfectant solution between a zero value and a non-zero nominal value. In addition, the pump is controlled by the control module so as to adjust the flow rate of cleaning and/or disinfectant solution to its nominal value for a predetermined duration corresponding to the delivery of a predetermined nominal volume of cleaning and/or disinfectant solution. by the distribution head.

The radio frequency communication module is configured to transmit and receive an outgoing or incoming modulated radio communication signal respectively.

The electrical power source is preferably a source of electrical energy, such as for example an electric battery housed in the distribution terminal. By way of non-limiting example, the electric battery may be of the lithium battery type. Alternatively, the electrical power source takes the form of an electrical connection device between the distribution terminal and a neighboring electrical network. This advantageous configuration makes it possible to easily electrically connect the distribution terminal in accordance with the second aspect of the invention with the neighboring electrical network. Advantageously, the electrical connection member of the distribution terminal is of the type of a female connection member, intended to be able to be coupled with a similar male connection member.

The radiofrequency communication module comprises (i) a Bluetooth-type telecommunications antenna and a modulation-demodulation unit electrically and operatively connected to the telecommunications antenna, and/or (ii) a near-field communication terminal ( NFC, English acronym meaning Near Field Communication) connected to the control module.

In addition, the dimensions of the distribution terminals 1 can be variable depending on their locations of use, and/or their frequencies of use.

The casing 10 of the distribution terminal 1 can be formed from any material making it compatible for integration into the public landscape and making it resistant to intensive use and/or bad weather. By way of non-limiting examples, the casing 10 can be formed entirely or partly from plastic or metallic materials.

In the exemplary embodiment illustrated in the , the lower part 13 of the casing 10 of the distribution terminal houses the tank 3 and the electronic system 2 in a specific housing 131. The housing 131 of the lower part 13 of the casing 10 is made accessible, in particular for maintenance and/or filling operations of the tank 3, by means of a removable or pivoting hatch 132, closed by a locking member 133 of the type of a lock.

The intermediate part 12 of the casing 10 of the dispensing terminal 1 comprises a cavity 122 inside which a user of the dispensing terminal 1 can insert his hands to receive the dose of cleaning and/or disinfectant solution. The cavity is advantageously located at a height of between 1000 mm and 1300 mm from the ground and/or from the base 14.

In its upper part 11, the casing 10 comprises a beveled part: a front face 110 of the casing 10 is inclined, so that the second lateral dimensions L2 of the casing 10 decreases as one approaches an upper vertical end of the distribution terminal 1. Finally, the upper part 11 of the distribution terminal 1 houses a visual communication device 111 making it possible to explain its operation and/or to carry out health awareness campaigns and/or broadcast advertisements. In the exemplary embodiment illustrated in FIGURES 1 and 2, the visual communication device takes the form of an integrated screen in order to allow interactive communication with users. The screen is preferably of the type of a liquid crystal screen (LCD) or a light-emitting diode (LED) screen or an organic light-emitting diode (OLED) screen, for example.

The distribution system 4 of the distribution terminal 1 makes it possible to deliver a predetermined dose of cleaning and/or disinfectant solution to a user of the distribution terminal 1. The distribution system 4 comprises a distribution head 121 in fluid communication with the reservoir 3 via at least one distribution pipe 42, and a pump configured to regulate a flow rate of cleaning and/or disinfectant solution circulating in the distribution pipe.

The distribution pipes 42 make it possible to place the reservoir 3 and the distribution head 121 in fluid communication in order to allow a routing of the cleaning and/or disinfectant solution towards the distribution head 121. Advantageously, the distribution pipes 42 of the distribution system 42 are hermetically coupled to reservoir 3 and to distribution head 121.

Reservoir 3 takes the form of a closed container configured to be able to accommodate a predetermined volume of cleaning and/or disinfectant solution. The volume of the tank is preferably between 0.5 liters and 10 liters. The tank is preferably housed in the lower part 13 of the distribution terminal 1 in order to promote its holding in a vertical station and for reasons of simplicity of design. Reservoir 3 is made of plastic or metal. Additionally, the tank 3 is hermetically closed in order to limit evaporation of the cleaning and/or disinfectant solution, and in order to reduce the risk of inflammation.

The distribution system 4 makes it possible to circulate the cleaning and/or disinfectant solution from the tank 3 in the direction of the distribution head 121, while controlling the flow rate of cleaning and/or disinfectant solution. The regulation of the flow rate of cleaning and/or disinfectant solution circulating in the distribution system 4 is ensured by the pump controlled by the control module 2C of the distribution terminal 1. The pump of the distribution system 4 is controlled by the control module control 2C of the electronic system 2 so as to adjust the flow rate of cleaning and/or disinfectant solution to a nominal value – not zero – for a predetermined duration corresponding to the delivery of a predetermined nominal volume of cleaning and/or disinfectant solution by the distribution head 121. When the nominal volume is reached, the control module 2C controls the pump so as to stop the flow of cleaning and/or disinfectant solution through the distribution head 121.

The dispensing head 121 of the dispensing system 4 is housed at the level of the cavity 122 of the intermediate part 12 of the casing 10. More specifically, in the embodiment illustrated in FIGURES 1 and 2, the dispensing head is housed at the level of an upper wall of the cavity 121, so that the cleaning and/or disinfecting solution can fall into the cavity by simple effect of gravity. This advantageous configuration makes it possible in particular to be able to recover in a recovery tank 5 a surplus of cleaning and/or disinfectant solution which would not have been used by the user of the distribution terminal 1. For this purpose, the cavity 122 comprises, at its lower wall opposite the dispensing head 121, a flow grid and a recovery duct fluidly coupled to the recovery tank.

The dispensing head 121 comprises one or more dispensing nozzles 1211 configured to release the cleaning and/or disinfectant solution and to allow a user of the dispensing terminal 1 to recover said solution and to apply it in particular to his hands, for example. . Depending on the desired effects and uses, the dispensing nozzle(s) 1211 forming the dispensing head 121 are configured to spray the cleaning and/or disinfectant solution in the form of droplets or in the form of a jet.

Optionally, the dispensing system 4 also comprises a sensor configured to measure a volume of cleaning and/or disinfectant solution housed in the reservoir 3. The sensor thus makes it possible to determine whether the remaining volume of cleaning and/or disinfectant solution falls below a value threshold requiring programming of a maintenance or filling operation for distribution terminal 1.

The distribution system 4 can also include a proximity sensor 1212 electrically connected to the control module 2C, the proximity sensor 1212 being configured to allow the activation of the distribution system 4 when a user of the distribution terminal 1 approaches his hands close to said dispensing terminal 1, and in particular close to the dispensing head 121. By way of non-limiting examples, the proximity sensor takes the form of an infrared sensor, an ultrasonic sensor , a capacitive sensor.

Preferably, but not limited to, the cleaning and/or disinfectant solution delivered by the dispensing terminal 1 in accordance with the first aspect of the invention is of the type of a hydroalcoholic solution or a solution containing a soap. Furthermore, the cleaning and/or disinfectant solution is delivered by the dispensing head 121 via doses of a predetermined volume and in a liquid state, of a gel, of a foam or of a nebulization for example.

With reference to the , the electronic system 2 of the distribution terminal 1 in accordance with the second aspect of the invention will now be described in more detail. As mentioned previously, the electronic system 2 is configured to enable all or part of the steps of the alert management method 6 in accordance with the first aspect of the invention and as it will be described in particular later on to be implemented. The electronic system 2 includes the power supply module 2A, the radio frequency communication module 2B and the control module 2C.

The electrical power supply module 2A is configured to provide the electrical energy necessary for the operation of the radio frequency communication module 2B and of the control module 2C, via an electrical power source 21. According to a first variant embodiment, the module of power supply 2A comprises a source of electrical energy allowing the distribution terminal 1 to operate independently. The source of electrical energy takes the form of an electric battery, rechargeable or non-rechargeable. Alternatively, the power supply module takes the form of an electrical connection member between the distribution terminal 1 and a neighboring electrical network. In this variant embodiment, the supply terminal does not house electrical energy sources, and the electrical connection member makes it possible to be able to easily electrically connect the distribution terminal 1 with the neighboring electrical network. By way of non-limiting example, the electrical connection member of the distribution terminal 1 is of the type of an electrical socket, female or male.

The power supply module 2A is thus formed of the power supply source 21 and of a conditioning device 22. The power supply source 21 thus makes it possible to generate a power supply signal making it possible to operate the other modules 2B, 2C of the electronic system 2; and the conditioning device makes it possible to adjust the electrical characteristics of the electrical power supply signal to the specificities required by each module 2B, 2C. By way of non-limiting example, the conditioning device makes it possible to selectively shape a voltage and/or an intensity and/or a frequency and/or a phase of the electrical power supply signal. The conditioning device 21 is configured to distinctly shape a first power supply signal for the radio frequency communication module 2A and a second power supply signal for the control module 2B.

The control module 2C is configured to control the various components of the distribution terminal 1, such as in particular the distribution system 4 and/or the proximity sensor 1212 and/or the screen forming the visual communication device 111. particular, the 2C control module comprises:

- a control device 27 of the proximity sensor 1212, configured to polarize the proximity sensor in order to be able to detect the presence of a user who has inserted his hands into the cavity 122 of the distribution terminal 1; and

- a controller 26 configured to control the pump and the dispensing head 121 of the dispensing system 4, the controller being configured to electrically supply the pump and/or the dispensing head 121 when the presence of a user having inserted his hands into the cavity 122 of the distribution terminal 1 has been detected by the proximity sensor 1212.

The radiofrequency communication module 2B is configured to transmit and receive a modulated radiocommunication signal respectively outgoing RFout or incoming Rfin. The outgoing modulated radio communication signal RFout is generated by the radio frequency communication module 2B and the incoming modulated radio communication signal R Fin is generated by a portable telecommunication device UL located close to the distribution terminal 1 and detected by said radio frequency communication module 2B.

To this end, the radiofrequency communication module 2B comprises:

- a processing unit 24 configured in particular to modulate the outgoing modulated radiocommunication signal RFout and to demodulate the incoming modulated radiocommunication signal RFin, according to a plurality of communication protocols; and

- A telecommunications antenna 23, 25 configured to transmit and/or receive a modulated radiofrequency signal.

The distribution terminal 1 according to the first aspect of the invention is configured to be able to communicate according to various protocols. Preferably, it is configured to be able to communicate selectively in Bluetooth or in near fields, according to the steps of its alert management method 6 or operation. The alert management method 6 in accordance with the first aspect of the invention and as implemented by the radiofrequency communication module 2B of the distribution terminal 1 will be described later with reference to the .

In the electronic system 2 shown in the , the radiofrequency communication module 2B comprises a Bluetooth antenna 23 and an NFC antenna 25, the processing unit 24 making it possible to communicate selectively according to one or the other of the communication protocols, according to the desired effects. The processing unit 24 thus simultaneously forms a modulation-demodulation unit electrically and operatively connected to the Bluetooth antenna 23, and a communication terminal electrically and operatively connected to the NFC antenna 25, as mentioned previously.

To facilitate the interaction between the portable telecommunication device UL and the distribution terminal 1, the Bluetooth antenna 23 and/or the NCF antenna 25 are preferably located at the level of the upper part 11 of the distribution terminal 1, in an intermediate position between the visual communication device 111 and the cavity 122, close to or housed in a cartridge 112 which is flush with the front face of the casing 10.

The processing unit 24 of the radio frequency communication module 2B advantageously comprises one or more controllers and/or one or more microprocessors and/or one or more microcontrollers and/or one or more programmable logic circuits (FPGA, English acronym meaning Field Programmable Gate Array) and/or one or more integrated circuits specific to an application (ASIC, English acronym meaning Application Specific Integrated Circuit). The processing unit 24 also includes a memory connected electrically and operationally to the antenna.

The electronic system 2 of the distribution terminal 1 in accordance with the second aspect of the invention takes the form of one or more electronic cards connected to each other – for example one for each module 2A, 2B, 2C – and with the distribution system 4 of the distribution terminal 1. By way of non-limiting examples, the electronic cards forming each module 2A, 2B, 2C of the electronic system 2 can comprise integrated circuits for processing the data exchanged between the control module 2C with the radiofrequency communication module 2B and the distribution system 4 and/or for controlling the radiofrequency communication module 2B, the distribution system 4 and the power supply module 2A. The integrated circuits can take the form of one or more controllers and/or one or more microprocessors and/or one or more microcontrollers and/or one or more programmable logic circuits (FPGA, English acronym meaning Field Programmable Gate Array) and/or one or more integrated circuits specific to an application (ASIC, English acronym meaning Application Specific Integrated Circuit).

Additionally, each module 2A, 2B, 2C forming the electronic system 2 can comprise and/or be connected to and/or be configured to access a memory configured to store digital data, of the type for example of a volatile memory and/or nonvolatile and/or cache and/or buffer memory and/or optical memory and/or erasable programmable read-only memory.

The illustrates a synoptic view of the alert management method 6 in accordance with the first aspect of the invention. The alert management method 6 makes it possible to identify a plurality of portable telecommunications devices UL having had an interaction with the distribution terminal 1 as described above in one or other of its variants, so as for example to obtain a dose of cleaning and/or disinfecting solution. To this end, the alert management method 6 comprises:

- a pairing step 61 of a UL portable telecommunications device with the distribution terminal 1 as described above;

- a step 62 of recording identification data relating to the portable telecommunication device UL;

- a step 63 for activating an alert function;

- an alert step 64 comprising the sending of a message to at least one portable telecommunication device UL whose identification data have been recorded previously, during a previous execution of the alert management method 6 .

In the alert management method 6 in accordance with the first aspect of the invention, the pairing step 61 and the recording step 62 can be carried out more than once before triggering the subsequent activation steps 63 and alert 64. In other words, the pairing 61 and registration 62 steps can be carried out according to a plurality of iterations, the activation step 63 possibly not being triggered systematically at such a pairing 61. Indeed, the alert management method 6 aims to systematically record the identification data of the portable telecommunications devices UL having interacted with the distribution terminal 1 so as to build a logbook of the various pairings made. Also, if necessary, in particular with regard to detection of a case of contamination by one of the users of the distribution terminal 1, then it is possible to use the logbook in order to warn all or part of the other users who have used distribution terminal 1.

The pairing step 61 allows a UL portable telecommunications device to reserve the use of the distribution terminal 1. In particular, the pairing step 61 includes:

- a step 611 of transmission of identification data of the portable telecommunication device UL by said portable telecommunication device UL to the distribution terminal 1;

- a step 612 for receiving identification data by the distribution terminal 1;

- a comparison step 613 during which the identification data is compared with a reference value. If the comparison is valid, that is to say if the identification data conforms to the reference value, then the portable telecommunication device UL is paired with the distribution terminal 1 and communication is established between the distribution terminal 1 and said portable telecommunication device UL. If the comparison is invalid, i.e. if the identification data is incompatible - i.e. does not conform - with the reference value, then the UL portable telecommunication device is not paired with distribution terminal 1, and no further communication is established between distribution terminal 1 and the portable telecommunications device UL. However, the subsequent step 62 of recording the identification data of the alert management method 6 is carried out regardless of the result of this comparison, whether the portable telecommunication device has been paired with the distribution terminal 1 or not.

During the step 62 of recording the identification data, these are recorded 626 on an internal memory of the distribution terminal 1 or on a remote network to which the distribution terminal 1 is connected via means of communication with the remote server, of the type for example of a GSM, 3G, 4G, 5G chip, or of the type of a wired or wireless connection to the remote server, such as for example an Ethernet connection, an internet connection or a connection of the type Wireless. More particularly, the recording step 62 includes:

- a step 622 of transmitting a telephone number associated with the portable telecommunications device UL to the distribution terminal 1, and/or a step 623 of transmitting an electronic mail address to said distribution terminal 1. The step 622 of transmitting the telephone number and/or the step 623 of transmitting the e-mail address is carried out by direct entry via a user interface of the distribution terminal 1, such as for example a touch screen housed on said distribution terminal 1 or via a wireless transmission between the distribution terminal 1 and the portable telecommunications device UL, such as for example via the establishment of a bluetooth or NFC communication;

- a time-stamping step 624 for determining a local time relating to the distribution terminal 1 and/or to the portable telecommunication device UL. The time-stamping step is carried out by the control module 2C of the distribution terminal 1, or the time-stamping step 624 is of the type of a transmission of said local time by the portable telecommunication device UL during its pairing step 61 with the distribution terminal 1, or the time-stamping step 624 is carried out on the remote server at or near the time at which the identification data is recorded on said remote server;

- a geolocation step 625 during which geolocation data of the distribution terminal 1 having transmitted the identification data is recorded.

The activation step 63 of the alert function takes the form of a local setting of the distribution terminal 1 or the reception of a specific activation command on the distribution terminal 1. As mentioned previously, the alert activation step 63 is performed after one iteration or several iterations of the pairing 61 and registration 62 steps.

In the case of local configuration of the distribution terminal 1, the terminal is configured manually by a user of said distribution terminal 1, for example via a specific graphical interface displayed on a display screen of the distribution terminal of so as to configure the distribution terminal in order to trigger the alert step 64.

In the case of remote parameter setting, via the reception of a specific activation command, such reception is ensured via the telecommunication means of the distribution terminal 1 or via the radiofrequency communication module 2B of the distribution terminal 1. The activation command is interpreted by the control module 2C of the distribution terminal 1 and makes it possible to configure the distribution terminal 1 so as to trigger the alert step 64. Alternatively, the activation command is interpreted centrally at the level of the remote server to which the distribution terminal 1 is connected. In this case, it is the remote server that activates the subsequent alert step 64. Thus, the distribution terminal 1 transfers to the remote server all the data necessary to carry out this activation step 64.

Optionally, the registration step 62 includes a prior authorization request step 621 to save the identification data. The authorization request step takes the form of sending an authorization message for recording identification data and a step of receiving confirmation or invalidation data. The step of sending the authorization request message is carried out by the distribution terminal 1, via bluetooth or NFC communication for example. The step of receiving the confirmation data includes a step of sending said confirmation data by the portable telecommunication device and a step of receiving said confirmation data by the distribution terminal. Preferably, the reception step is carried out through a Bluetooth or NFC communication protocol as described above.

The purpose of the alert step 64 is to warn users who have used the distribution terminal during a certain given period of time. Thus, the alert step 64 aims to determine the relevant identification data with regard to the activation command, in order to be able to send an alert message to the users concerned. To this end, the alert step 64 includes a step 641 for selecting a critical set formed by part of the identification data previously recorded. This step makes it possible to determine which users – through the identification data exchanged with distribution terminal 1 and their UL portable telecommunications device – are to be notified subsequently. In particular, the critical set is determined – for each portable telecommunication device UL with which the identification data is associated – by a step 642 of comparing at least one of the identification data with a reference value transmitted during step 63 for activating the alert. The reference value includes:

- a critical time, the critical set then being formed by all or part of the identification data corresponding to the UL portable telecommunications devices whose timestamp data is located close to the critical time;

- a critical geographic coordinate – relative or absolute – such as for example a GPS coordinate or triangulation data, the critical set then being formed by all or part of the identification data corresponding to the UL portable telecommunications devices whose geolocation is located near the critical geographic coordinate.

The critical set, determined during the selection 641 and comparison 642 step, can be carried out centrally on the remote server or locally on the distribution terminal 1.

The alert management method 6 further comprises a final step 65 of deletion of the identification data of the critical set. The deletion step is carried out periodically, according to a given reset period, for example equal to 15 days.

In summary, the invention relates to a method for managing the alert of several users of one or more distribution terminals 1 of a cleaning and/or disinfecting solution by using identification data transmitted by said users via their respective UL portable telecommunications devices to the distribution terminal 1 that they used and to which their UL portable telecommunications device was paired. In the event of detection of proven contamination, the alert management method thus makes it possible to identify the list of users who have used the distribution terminal 1 during a brief period located before or after the use of said distribution terminal 1 by a contact case. The invention thus makes it possible to reduce the spread of viruses and contaminants within the population and to facilitate the identification of contact cases.

Of course, the invention is not limited to the examples which have just been described and many adjustments can be made to these examples without departing from the scope of the invention. In particular, the different characteristics, forms, variants and embodiments of the invention may be associated with each other in various combinations insofar as they are not incompatible or exclusive of each other. In particular, all the variants and embodiments described above can be combined with one another.
