Method for securing users travelling with different means of transport in a geographical area

Abstract

The invention relates to a safety method for signaling, within a given geographical area (G), the presence of vulnerable road users traveling on foot or with a non-motorized or electrically assisted vehicle, referred to as first users, to road users traveling by motorized vehicle, referred to as second users; this with the aim of improving road safety and minimizing the risk of collisions. The safety method consists first of geolocating the positions (p11, p12) of the first users and the positions (p21) of the second users within the geographical area, then associating a virtual safety zone (z21) around each second user's respective position. The safety method is then configured to alert the second users of the proximity of the first users when the latter's position enters their virtual safety zone. Abstract figure: Figure 9

Description

Title of the invention: Method for securing users traveling with separate means of transport in a geographical area Technical field

[0001] The invention relates to a method for securing users moving around in a geographical area.

[0002] It relates more particularly to a security method for geolocating users traveling on foot, by bicycle or by vehicle in a geographical area, and informing users traveling by vehicle of the nearby presence of users considered to be vulnerable, i.e. for example traveling on foot or by bicycle, in order to prevent accidents.

[0003] The invention finds a preferred, and non-limiting, application in the fields of road safety and construction site safety, by improving the vigilance of drivers of vehicles or construction site machinery, with respect to other users traveling on foot or with a non-motorized or electrically assisted cycle. Prior art

[0004] As is known, in a given geographical area (for example an urban area, a rural area, a construction site area, etc.) in which many users travel, a high number of accidents involve a user traveling with a motorized vehicle (such as a car, a utility vehicle, a truck, construction equipment, etc.) and a so-called "fragile" user, i.e. a user traveling either on foot or by means of a non-motorized or electrically assisted vehicle (such as a bicycle, a scooter, etc.). These accidents can cause serious injuries to fragile users. In the worst case, they can be fatal. For example, in 2022, France recorded 2,626 serious injuries and 244 deaths related to accidents involving cyclists and motorized vehicles, and 570 serious injuries and 34 deaths related to accidents involving unicycles or scooters with motorized vehicles.

[0005] These accidents can occur due to a failure by users, whoever they may be, to comply with safety rules (road safety rules, construction site safety rules, etc.) but also due to a lack of vigilance. Summary of the invention

[0006] In order to prevent accidents and thus limit their number, the invention aims to reinforce the safety of users moving in the same geographical area, by improving their vigilance, in particular that of users of motorized vehicles with regard to the presence of users considered to be vulnerable. (such as pedestrians; people traveling by non-motorized or electrically assisted cycles such as scooters, bicycles, etc.).

[0007] To this end, the invention proposes a security method for securing at least one first user moving in a geographical area using a first means of movement belonging to a first category of means of movement, and within which at least one second user is moving using a second means of movement belonging to a second category of means of movement distinct from the first category of means of movement, said security method comprising the following steps: - a step of geolocation of at least one first user in the geographical area, giving in real time his position in said geographical area; - a step of geolocation of at least one second user in the geographical area, giving in real time their position in said geographical area; - an association step during which a virtual safety zone describing a circle centered on the position of the at least one second user and having a radius which is either established according to a typology of the geographical zone and / or the second category of means of transport, or configurable by said at least one second user, is associated with the at least one second user; - a danger detection step during which a danger is detected when the position of the at least one first user enters the virtual safety zone of the at least one second user; - an alert step taking place after the danger detection step and during which at least one second user is warned of the danger by at least one alert.

[0008] In other words, the geolocation security process locates in real time in a given geographical area the positions: - at least one user considered to be fragile, qualified as a first user and traveling by means of a means of transport qualified as a first means of transport; and

[0009] - of at least one user considered dangerous, qualified as a second user and moving by means of a second means of movement which corresponds for example to a motorized vehicle.

[0010] The security method associates with the position of the at least one second user a virtual security zone describing a circle centered on said position and the radius of which is: either established according to the typology of the geographical zone and / or the category of the second means of transport (for example motorcycle, car, van, truck, etc.), or configured by the at least one second user himself.

[0011] Advantageously, the security method is designed to alert the at least one second user of the presence and proximity of the at least one first user in its virtual safety zone.

[0012] Advantageously, the safety method makes it possible to improve the safety of the at least one first user when he moves in the geographical area by allowing him to signal himself to the at least one second user, only in the event of too great proximity (because in the virtual safety zone); which second user can then adapt his driving in order to: react / make decisions more quickly and safely, and / or avoid potentially dangerous situations involving the at least one first user (in the worst case, a collision with the at least one first user). The safety method therefore makes it possible to improve road safety.

[0013] According to a characteristic of the invention, the typology of the geographical area is a population density or a level of urbanization, so that the radius of the virtual security zone of the at least one second user evolves according to the population density or the level of urbanization of the geographical area.

[0014] The risks of an accident on the road involving at least one first user and at least one second user within the meaning of the invention are higher in geographical areas for which the level of urbanization and / or population density is the highest because road traffic is higher there (with a higher probability of situations of intense traffic, dense traffic, traffic in single file, etc.). In other words, the risks of an accident involving at least one first user and at least one second user are higher in a large metropolis (i.e. an urban area) than in the countryside (i.e. a rural area).

[0015] Advantageously, the security method adapts the radius of the virtual security zone of the at least one second user according to the typology of the geographical zone in which he / she moves / moves.

[0016] Another advantage of the security method is that it adapts in real time the radius of the virtual security zone if the at least one second user, when moving, passes from a first geographical zone having a given population density and / or level of urbanization to a second geographical zone having a higher or lower population density and / or level of urbanization.

[0017] According to a characteristic of the invention, the typology of the geographical area is categorized into at least three typologies: - an urban typology associated with a first population density or a first level of urbanization, the radius of the virtual security zone of the at least one second user having a first radius value for this urban typology; - a peri-urban typology associated with a second population density lower than the first population density, or with a second level of urbanization lower than the first level of urbanization, the radius of the virtual safety zone of the at least one second user having a second radius value for this peri-urban typology which is greater than the first radius value; - a rural typology associated with a third population density lower than the second population density, or with a third level of urbanization lower than the second level of urbanization, the radius of the virtual security zone of the at least one second user having a third radius value for this rural typology which is greater than the second radius value.

[0018] In other words, the higher the level of urbanization and / or population density of a geographical area, the smaller the radius of the virtual safety zone.

[0019] According to one embodiment of the invention, the first radius value is at least equal to 60 meters, plus or minus 30 meters.

[0020] According to one embodiment of the invention, the second radius value is at least equal to 130 meters, plus or minus 30 meters.

[0021] According to one embodiment of the invention, the third radius value is at least equal to 300 meters, plus or minus 50 meters.

[0022] In other words, in one embodiment of the invention: - when the geographical area is an urban area, the radius of the virtual security zone of at least one second user is at least 60 meters, plus or minus 30 meters; - when the geographical area is a peri-urban area, the radius of the virtual safety zone of at least one second user is at least 130 meters, plus or minus 30 meters; when the geographical area is a rural area, the radius of the virtual security zone of at least one second user is at least 300 meters, plus or minus 50 meters;

[0023] According to one embodiment of the invention, the geographical zone is a restricted access activity zone and the radius of the virtual security zone of the at least one second user is established solely as a function of the second category of means of transport.

[0024] Indeed, a restricted access activity zone forms a closed zone, with secure or limited access, and inside which different users circulate, and in this case it is the or each second user who will configure the radius of the virtual security zone, for example according to internal regulations specific to the zone which define the radius according to the category of the second means of transport.

[0025] In one embodiment of the invention, the restricted access activity zone is an industrial zone, or a port zone, or an industrial-port zone, or an airport zone, or a construction site.

[0026] Advantageously, the protection of the at least one first user by means of the The security process can be extended to other application contexts than road traffic. The security process can in particular improve the safety of at least one first user when carrying out an activity in a restricted access activity zone (which, non-exhaustively and indicated above, may correspond to an industrial zone, a port zone, a construction site, etc.) in which he is required to come into contact with at least one motorized vehicle driven by at least one second user.

[0027] For example, in the case of a construction site, the safety method is designed to increase the vigilance of drivers of construction equipment (trucks, special equipment such as backhoe loaders and excavators, etc.) by alerting them to the presence of vulnerable users (such as workers moving around the site on foot), thus making it possible to avoid the risk of collision between at least one first user and a second user and therefore potentially fatal work accidents for the at least one first user.

[0028] In the case where the geographical area in which the security method is implemented is a restricted access activity area, the radius value of the virtual security zone depends for example solely on the category (in other words the type) of vehicle driven by the at least one second user.

[0029] According to one embodiment of the invention, the radius of the virtual safety zone of the at least one second user is pre-recorded or is configured by the at least one second user prior to the movement.

[0030] In the case where the geographical area is a restricted access activity zone, the radius of the virtual security zone is: - either pre-recorded, for example in a program implementing the security process and which is contained in an electronic device, the pre-recording having been carried out by a person other than the at least one second user (for example, a technical operator working in the same restricted access activity zone as the at least one second user); - be configured by at least one second user himself before starting (and therefore prior to moving) the second means of transport (for example using the same electronic device as that just mentioned).

[0031] According to a characteristic of the invention, the first category of means of movement is chosen from:

[0032] - a pedestrian means; and

[0033] - a non-motorized or electrically assisted vehicle comprising at least one wheel, such as a bicycle or a scooter.

[0034] In other words, the at least one first user, who is considered a vulnerable user, is either a pedestrian or a person traveling by means of a vehicle. non-motorized or electrically assisted.

[0035] According to one embodiment of the invention, the method comprises:

[0036] - a step of detecting a fall during which a fall of the au is detected less than a first user,

[0037] - a fall alert step following the fall detection step, during which is issued to at least one first user at least one fall alert;

[0038] such that:

[0039] - if the at least one first user does not carry out a predefined stopping action in a predetermined delay from the at least one fall alert, and if the at least one second user is located below a given reporting distance from the position of the at least one first user, then a fall reporting step is automatically carried out during which the at least one second user is warned by a fall reporting alert of the fall of said at least one first user and receives the position of the at least one first user;

[0040] - if the at least one first user carries out the predefined stop action within the predefined time limit determined from at least one fall alert, then the fall reporting step is not carried out

[0041] Advantageously, the securing method is capable of: - to detect a fall of at least one first user, regardless of the cause; - then transmit a fall reporting alert and the position of the at least one first user to the at least one second user who warns him of the fall of the at least one second user, if the position of the at least one second user is within a given reporting distance from the position of the at least one first user.

[0042] The fall reporting step during which a fall reporting alert and the position of the at least one first user are transmitted to the at least one second user is implemented on the condition that the at least one first user has not carried out a stopping action within a predetermined time following the fall detection step.

[0043] The performance or non-performance of this stopping action may result in a state of at least one first user: in full possession of his means and capacities to perform the stopping action; injured or unconscious.

[0044] Advantageously, the reception of the fall reporting alert by the at least one second user allows him to go to where the at least one first user fell, and / or to provide assistance to him, and / or to alert emergency services (fire brigade, hospitals, etc.)

[0045] In an alternative embodiment of the security method, the fall reporting alert and the position of the at least one first user are also sent to the other first users present in the geographical area if their position is within the reporting distance.

[0046] In one embodiment of the invention, the reporting distance is equal to 3 kilometers, plus or minus 1 kilometer.

[0047] According to a characteristic of the invention, the second category of means of transport is a motorized vehicle comprising at least four wheels, such as for example a car, a van, a truck or construction equipment.

[0048] In one embodiment of the invention the method comprises:

[0049] - an additional association step during which is associated with the at least one second user an additional virtual security zone describing a circle centered on the position of the at least one second user and having a fixed radius less than the radius of the virtual security zone;

[0050] - an additional danger detection step during which a danger imminent is detected when the position of the at least one first user enters inside the additional virtual security zone of the at least one second user;

[0051] - an additional alert step taking place after the additional step of danger detection and during which at least one second user is warned of the imminent danger by at least one additional alert.

[0052] As previously indicated, the reporting step makes it possible to signal to the at least one second user the presence and proximity of the at least one first user in the geographical area, so that the at least one second user increases their vigilance and adapts their driving accordingly.

[0053] In one embodiment of the invention, through the implementation of the additional steps cited above, the security method advantageously signals to the at least one second user that the at least one first user has moved closer to him (since the additional virtual security zone is included within the virtual security zone defined until then), and therefore that the risk of a collision between them is much higher (and therefore of imminent danger), meaning that he must be even more vigilant.

[0054] The additional alert step also has the advantage of re-warning the at least one second user of the presence and proximity of the at least one first user in the geographical area. Indeed, in a worst-case situation, because he was distracted, the at least one second user may not have paid attention to the first alert.

[0055] Implementing additional steps to signal the rapprochement of the au less than one first user is advantageous when the at least one second user and he are both moving (for example, in a context of heavy traffic or traffic in a queue), but is also of interest when the at least one second user is carrying out a maneuver with his motorized vehicle, the attention of the at least one second user being focused more on said maneuver than on his environment. By way of illustration and not limitation, the additional alert step is of interest when the at least one second user, who is driving a truck, has to reverse in a curve with it and his field of vision is obstructed by a trailer that the truck is towing, preventing him from seeing a pedestrian who may be moving near the trailer or behind it.

[0056] In one embodiment of the invention, the fixed radius of the additional virtual security zone is equal to 15 meters, plus or minus 5 meters.

[0057] In one embodiment of the invention, the method comprises a step of displaying in an online plan displayed on a screen intended for the at least one second user, at least: the position of the at least one second user with an illustration of his virtual security zone, and the position of the at least one first user.

[0058] Advantageously, the real-time display of the position of the at least one first user and of his own position allows the at least one second user to be constantly informed of the presence of the at least one first user in the geographical area, meaning that he can adapt his driving himself and be vigilant according to a given traffic situation even before possibly receiving an alert to inform him of the relative proximity of the at least one second user and therefore of a potential danger.

[0059] In one embodiment of the invention, the method comprises a step of displaying in an online plan displayed on a screen intended for the at least one first user, the position of the at least one first user.

[0060] In one embodiment of the invention, the method comprises declaration steps during which, prior to their respective movements in the geographical area, the at least one first user and the at least one second user declare their respective categories of means of transport.

[0061] In other words, by declaring to travel with a first means of travel or a second means of travel within the meaning of the invention, the user declares himself as being at least a first user or at least a second user.

[0062] Advantageously, the declaration steps allow the design of devices implementing the security method which are not specifically dedicated to at least one first user and at least one second user.

[0063] In one embodiment of the invention, the securing method is implemented implemented at least by a mobile application which is downloaded and then contained in a mobile terminal connected and transported by at least one first user, called the first terminal, and in a mobile terminal connected and transported by at least one second user, called the second terminal, the mobile application also serving to put the first terminal and the second terminal in communication with a remote server; and for which:

[0064] - the step of geolocating the at least one first user is implemented by the mobile application of the first terminal,

[0065] - the step of geolocating the at least one second user is implemented by the mobile application of the second terminal,

[0066] - the position of the at least one first user and the position of the at least one second user are transmitted in real time by the first terminal and the second terminal respectively to the remote server,

[0067] - data relating to the first category of means of transport and data relating to the second category of means of transport are transmitted by the first terminal and the second terminal respectively to the remote server,

[0068] - the radius of the virtual security zone of the at least one second user is either established by the mobile application of the second terminal and transmitted to the remote server, or established by the remote server,

[0069] - the association step is implemented by the remote server or by the application mobile of the second terminal,

[0070] - the danger detection step is implemented by the remote server, which sends a danger notification to the second terminal following the danger detection step, and

[0071] - the mobile application of the second terminal implements the alert step once re received the danger notification from the remote server.

[0072] According to one embodiment of the invention, the declaration steps are carried out when launching the mobile applications.

[0073] According to one embodiment of the invention, when the security method is implemented at least by a mobile application contained in the second terminal, the alert corresponds non-limitingly to: a text message displayed on a screen of the second terminal, an audible alert emitted by a loudspeaker of the second terminal, a vibration of the second terminal.

[0074] In a particular embodiment, the alerting step comprises activation of a light and / or sound warning system arranged on the second movement means.

[0075] According to one embodiment of the invention, the warning system is a rotating beacon.

[0076] According to an alternative embodiment of the invention, at least part of the securing method is implemented by an electronic device which is arranged on the second movement means, and which contains a program designed to implement at least the following steps of the securing method: - the geolocation step of at least one second user, and - the alert stage for which the electronic device sends an activation signal to the light and / or sound warning system.

[0093] [Detailed description of one or more embodiments of the invention]

[0094] The invention relates to a security method 1, in a first application context, contributing to the improvement of road safety in a geographical zone G in which the following people travel: - at least one first user ul 1, ul2 who uses a first means of transport ml 1, ml2 belonging to a first category of means of transport cl 1, c 12; and - at least one second user u21, u22 who uses a second means of transport m21, m22 belonging to a first category of means of transport c21, c22, c23, c24.

[0095] For the purposes of the invention, the first category of means of movement cl 1, cl2 refers to: - a pedestrian means c 12; and

[0096] - a non-motorized or electrically assisted vehicle comprising at least one wheel, such as a class 1 cycle or a scooter.

[0097] In the sense of road safety, the at least one first user ul 1, ul2 relates to a fragile user (or vulnerable user), that is to say a user using the public highway and not benefiting from (or little) protection in the event of a collision, which collision may prove fatal.

[0098] The second category of means of transport c21, c22, c23, c24 refers to motorized vehicles comprising at least four wheels, for example and not limited to: a car c21, a van, a truck c22 or a construction machine c23, c24.

[0099] An example of geographical area G is given [Fig.l]-a, in which the following move: - two first users ul 1, ul2 who in the remainder of the description are respectively called first user ul 1 and other first user ul2. The first user ul 1 uses a first means of transport mil corresponding to a bicycle / cycle cil, i.e. a non-motorized two-wheeled vehicle. The other first user ul2 moves on foot (he therefore uses a first means of transport ml2 corresponding to a pedestrian means cl2); - two second users u21, u22 who in the remainder of the description are respectively called second user u21 and another second user u22. The second means of transport m21 with which the second user u21 travels is a car c21, and the second means of transport m22 with which the other second user u22 travels is a truck c22.

[0100] In order to improve the safety of vulnerable users and prevent any risk of collision, the safety method 1 is designed to signal to at least one second user u21, u22, who is moving in a geographical zone G, the presence of at least one first user ul 1, ul2 who is nearby, with the aim that the at least one second user u21, u22 increases their vigilance and adapts their driving accordingly (for example, by driving more slowly or by being able to react / make decisions more quickly and reliably).

[0101] The security method 1 is suitable for all types of traffic and traffic situations: fluid, moderate or intense traffic; dense traffic; traffic in single file, etc.

[0102] The operating principle of the security method 1 is explained based on Figures 1 and 2.

[0103] The operating principle of the security method 1 is explained through the flowchart of [Fig.2] taking into consideration the first user ul 1 and the second user u21.

[0104] Following a start-up step E0 for which its implementation begins, the security method comprises two geolocation steps EG1, EG2 which can be carried out in parallel as illustrated [Fig.3]. For one of the two geolocation steps EG1, the security method 1 geolocates and gives the position pl 1 in real time of the first user ul 1 in the geographical area G. For the other of the two geolocation steps EG2, the security method 1 geolocates and gives the position p21 in real time of the second user u21 in the geographical area G.

[0105] Following the geolocation of the second user u21, the geolocation method 1 associates with it during an association step EA a virtual security zone z21 describing a circle centered on the position p21 of the second user u21 and of radius r21. The definition of the radius r21 is given later in the description.

[0106] The security method 1 then implements a verification step Q1 during which it compares the distance between the position pl 1 of the first user and the position p21 of the second user with the radius r21 of the virtual security zone z21.

[0107] In the case where the distance between the two positions p1, p21 remains greater than the radius r21, the security method 1 continues to implement the geolocation steps EG1, EG2 and association EA.

[0108] When the distance between the two positions p1, p21 becomes less than or equal to the radius r21, the securing method 1 then detects during a danger detection step ED that the position p1 of the first user is contained inside the virtual safety zone z21, therefore that he is close to the second user u21 and that a danger / risk of collision between them is possible.

[0109] Following the danger detection step ED, the security method 1 implements an alert step EW during which the second user u21 is warned of the danger by an alert wl.

[0110] In an alternative embodiment, as illustrated [Fig.2], it is conceivable that the security method 1 implements the alert step EW only once, and only subsequently repeats in real time the geolocation steps EG1, EG2 and display EA. For this, following the danger detection step ED, the verification method 1 verifies during a verification step Q3 whether or not the alert step EW has already been carried out, in other words whether or not the second user 21 has been warned of the danger and proximity to the first user ul 1.

[0111] In another variant embodiment, the EW alert step is implemented several times if the security method 1 continues to detect that the position of the first user ul 1 is inside the virtual security zone z21 of the second user u21. In this case, a time delay can be defined between the implementations of two successive EW alert steps.

[0112] More generally: - the geolocation steps EG1, EG2 respectively take into consideration all the first users ull, ul2 and second users u21, u22 present in the geographical zone G, - a virtual security zone z21, z22 is associated with each of the second users u21, u22, and - all of steps Ql, ED, Q3, and EW are applied to the different second users with respect to each of the first users. In other words, if a geographical area G has a number m of first users and a number n of second users, steps Ql, ED, Q3, and EW are applied to m*n pairs such that a pair is formed by a first user and a second user. In the example of [Fig.l], steps Ql, ED, Q3, and EW apply to 4 pairs of users formed by: the first user ul 1 and the second user u21; the other first user ul2 and the second user u21; the first user ul 1 and the other second user u22; and the other first user ul2 and the other second user u22.

[0113] In the case of a single signal of a danger, and according to what has just been described, this means that a second user u21, u22 will be alerted by an alert wl for any first user u11, ul2 entering at a time t in his virtual safety zone z21, z22. On the other hand, he is not alerted by an alert wl of the presence of a first user u11, u12 who entered the virtual safety zone z21, z22 at a time t-1 and would still be inside at time t.

[0114] With reference to the example described [Fig.l], at a time t, the security method 1 geolocates the positions pl 1, pl2 of the first two users u11, u22 and the positions p21, p22 of the second two users u21, u22 and then associates with each of the two second users u21, u22 a virtual security zone z21, z22 ([Fig.l]-a and [Fig. l]-b). In this situation, no danger is detected by the security method 1: neither of the first two users is in the virtual security zone of the second user u21 or of the other second user u22. At a time t+1 ([Fig.l]-c and [Fig.l]-d), according to the directions of movement indicated in [Fig.l]-a, the securing method 1 determines that the position pl 1 of the first user ull enters the virtual security zone z21 of the second user u21 (at the end of the verification step Ql). It then implements the steps Ql, ED, Q3, and EW in accordance with what was previously described.

[0115] During the association step EA, the radii r21, r22 of the virtual security zones z21, z22 of the second user u21 and of the other second user u22 are, in a first embodiment, calculated according to the TG typology of the geographical zone G.

[0116] For the purposes of the invention, a TG typology is defined by a population density or a level of urbanization.

[0117] With reference to [Fig.3], at least three typologies are considered: - an urban typology TGI associated with a first population density or a first level of urbanization, the radius r21, r22 of the virtual security zone z21, z22 then having a first radius value vall at least equal to 60 meters, plus or minus 30 meters;

[0118] - a peri-urban typology (not illustrated in [Fig.3]) associated with a second population density lower than the first population density, or at a second level of urbanization lower than the first level of urbanization, the radius r21, r22 of the virtual safety zone z21, z22 then having a second minimum radius value equal to 130 meters, plus or minus 30 meters;

[0119] - a rural typology TG3 associated with a third population density lower than the second population density, or at a third level of urbanization lower than the second level of urbanization, the radius r21, r22 of the virtual safety zone z21, z22 then having a third radius value val3 at least equal to 300 meters, plus or minus 50 meters.

[0120] In a second embodiment of the invention, the radii r21, r22 of the virtual safety zones z21, z22 of the second user u21 and of the other second user u22 are calculated as a function of the typology TG of the geographical zone G, but also as a function of the second category of means of transport c21, c22, c23, c24. With reference to [Fig.l], the virtual safety zone z22 associated with the other second user u22, who drives a truck c22, has a radius r22 greater than the radius r21 of the virtual safety zone z21 associated with the second user u21, who drives a car c21. Thus, the increase in the radius r21, r22 of the virtual safety zone z21, z22 may be based on: the difficulty in maneuvering the second category of means of transport c21, c22, c23, c24, the field of vision of the at least one second user u21, u22 (for example, the driver of a truck may have his field of vision at the rear of the vehicle partially obstructed by a trailer).

[0121] In a third embodiment of the invention, the security method 1 allows the at least one second user u21, u22 to define himself the radius r21, r22 of his virtual security zone z21, z22, for example during a configuration step taking place following the start step E0 and before the geolocation step EG2.

[0122] In a fourth embodiment, with reference to [Fig.4], the securing method 1 is used to improve the safety of vulnerable users such as workers. who work in restricted access activity zones such as industrial zones, port zones, industrial-port zones, airport zones, construction sites, etc. in which they carry out their activity and move among motorized vehicles, for example c23 backhoe loaders or c24 mobile cranes in the case of construction sites, again to minimize potentially lethal collision risks.

[0123] In this embodiment, the radii r21, r22 of the virtual safety zones z21, z22 of the second users u21, u22 depend solely on the second category of means of movement c21, c22, c23, c24. The definition of the radius r21, r22 can here also be based on: the difficulty in maneuvering the second category of means of movement c21, c22, c23, c24, the field of vision of the at least one second user u21, u22, etc. A backhoe loader c23 will for example be easier to maneuver in the construction site than a mobile crane c24. The value of the radius r21, r22 in this embodiment is intended to be either predetermined and recorded in a device implementing the securing method 1, or configured by the at least one second user u21, u22 during a configuration step taking place after the launch of the securing method and prior to the movement of the second movement means m21, m22.

[0124] In one embodiment of the invention, with reference to [Fig.5], it is provided that the at least one second user u21, u22 is warned of the proximity of the at least first user ul 1, ul2 by at least two alerts wl, w2 such that: - the first alert corresponds to the alert wl described so far and implemented when the at least first user ul 1, ul2 enters the virtual security zone z21, z22 at a time t ([Fig.5]-a and [Fig.5]-b); - the second alert corresponds to an additional alert w2 having the function of alerting the at least one second user ul 1, u22 of an imminent danger due to a proximity of the at least one first user ul 1, ul2 at a time t+1 ([Fig.5]-c and [Fig.5]-d).

[0125] The second alert is intended to be implemented when the at least one first user u11, ul2 enters an additional virtual security zone z21_2 describing, just like the virtual security zone z21, z22, a circle centered on the position p21, p22 of the at least one second user u21, u22. The radius of the additional virtual security zone z21_2 is defined as a fixed radius r21_2 smaller than the radius r21, r22 of the virtual security zone z21, z22. The fixed radius r21_2 is predetermined in the security method 1: it is independent of the typology of the geographical zone G and of the second category of means of transport c21, c22, c23, c24; and it cannot be configured by the at least one second user u21, u22.

[0126] In one embodiment of the invention, the fixed radius r21_2 is equal to 15 meters, more or less 5 meters.

[0127] An example of implementation of the security method 1 implementing the additional alert w2 is shown [Fig.6], and for which the first user ul 1 and the second user u21 are considered. It should be noted that the implementation in this example of the alert wl remains similar to that of [Fig.2].

[0128] The additional virtual security zone z21_2 is associated with the second user u21 during an additional association step EA2 which can be implemented after the association step EA (as illustrated in [Fig.6]). In another alternative embodiment, it is possible to parallelize the two association steps EA1, EA2.

[0129] Following the danger detection step ED, the securing method implements the verification step Q3 to check whether or not the alert step EW has already been carried out (in other words, whether the second user u21 has been warned by the alert wl of the presence of the first user ul 1 in the virtual security zone z21. If this is not the case, the alert step EW is carried out. If this is the case, the securing method then implements a verification step Q2 during which it checks that the distance separating the position pl 1 of the first user ul 1 and the position p21 of the second user u21 is less than or equal to the fixed radius r21_2. If so, the securing method 1 implements an additional danger detection step ED2 during which it detects an imminent danger between the two users ul 1, u21, since the position pl 1 of the first user ul 1 entered the additional virtual security zone z21_2 of the second user u21.

[0130] Following the additional danger detection step ED2, an additional alert step EW2 is then carried out during which the second user u21 is warned of the imminent danger by the additional alert w2.

[0131] The additional alert w2 allows: - further increase the vigilance of the second u21 user by signaling to him that the first user is much closer to him than before, - re-warn the second user u21 of the presence and proximity of the first user ul 1, because the second user u21 may have been distracted and not paid attention to the alert wl

[0132] The additional alert w2 is advantageous for signaling the approach to the second user u21 of the proximity of the first user 11 when they are both moving (see [Fig.5]), but also in the case where, for example, the first user ul 1 approaches while the second user u21 performs a maneuver with his motorized vehicle (for example, a parking space or reversing to park) and his attention is more focused on his maneuver than on his close environment. Possibly, if the motorized vehicle is a truck c22, the field of vision of the second user may be obstructed by a trailer if he has to reverse in a curve.

[0133] Similar to the alert wl, and as illustrated [Fig.6], the security method 1 can be configured so that the second user is warned only once by the additional alert w2. In this case, the security method comprises, between the additional danger detection step ED2 and the additional alert step EW2, a verification step Q4 during which the security method verifies whether or not the second user u21 has been warned by the additional alert w2 (in other words, whether or not the additional alert step EW2 has been carried out). In an alternative embodiment, it is conceivable that the second user is warned by several successive additional alerts w2 separated in time by a delay.

[0134] More generally, the security method 1 described [Fig.6] applies to the m*n pairs of m first users ul 1, ul2 and n second users u21, u22 present in the geographical zone G.

[0135] The securing method, in one embodiment, with reference to [Fig.7] and 8, is also designed to detect a fall of the first users ul 1, u22 independently of the first category of means of transport cl 1, c 12 (the fall detection therefore applies to both pedestrians and people traveling with a cycle), then signal it at least to second users u21, u22 close to the at least one first user ul 1, ul2 having fallen. The explanation of the fall detection and signaling steps is given, with reference to the Figure, considering the first user ul 1 and the second user u21, but they are generalizable to all the first users u11, ul2 and second users u21, u22 moving in the geographical area.

[0136] The detection and reporting of a fall is made possible once the geolocation steps EG1, EG2 have been implemented.

[0137] The fall of the first user ull is detected during a fall detection step FD. After the security method 1 has detected the fall, it implements a fall alert step FW during which at least one fall alert wf is issued at a time t to the first user ul 1. From this time t (i.e. at the end of the fall alert step), the first user must, within a predetermined time period d_act, perform an action called a stop action act. The security method 1 thus comprises a waiting step Q5 during the time period d_act during which it is waiting for this stop action act.

[0138] The purpose of carrying out or not the stopping action within the allotted time is to inform the safety method 1 (more precisely, a device / system implementing it) about the condition of the first user ull following his fall. The latter may in fact be in full possession of his faculties, or may need assistance, be unconscious, etc.

[0139] If the stop action act was carried out by the first user ul 1, the fall is not reported.

[0140] If the stopping action has not been carried out, the securing method 1 implements a verification step Q6 during which it checks whether the distance between the position of the second user u21 and the position of the first user ul 1 is less than or equal to a designated reporting distance. If yes, the securing method 1 implements a fall reporting step FS during which the second user u21 is alerted by a fall reporting alert swf of the fall of the first user ul 1, and also receives the position pl 1 of the first user ul 1.

[0141] More generally, the fall reporting alert swf and the fall of at least one first user ul 1, ul2 is sent to any second user u21, u22 located within the given designated reporting distance from the position pl 1, pl2 of the at least one first user ull, ul2. In the example given [Fig.7], the second user u21 and the other second user u22 are warned of the fall of the first user ull because both are included in the designated reporting distance.

[0142] In one embodiment of the invention, the designated signaling distance is equal to 3 kilometers, plus or minus 1 kilometer.

[0143] In one embodiment of the invention, it is conceivable that the designated signaling distance depends on the typology TG of the geographical area G. Indeed, the at least one first user ull, ul2 has a higher probability of being assisted in a populated geographical area G than in an isolated and / or little-used geographical area. In the worst case, this isolation could endanger the life of the at least one first user ull, ul2 in the event of serious injuries or if he is unconscious. This is why it is conceivable that the signaling distance could be greater for a rural typology TG3 than for an urban typology TGI.

[0144] In one embodiment, it is conceivable that the fall alert wf is also received by any first user ull, u21 whose position pl 1, pl2 is included in the designated reporting distance.

[0145] In one embodiment of the invention, with reference to Figures 9 and 10, the security method 1 is implemented within the framework of a SaaS (Software-as-a-Service) solution involving connected mobile terminals sll, s21 and a remote server 12. More precisely, the security method 1 is implemented by a mobile application 10 which is contained in connected mobile terminals sll, s21 carried by each of the first users ull, ul2 and second users u21, u22, after having been previously downloaded. The connected mobile terminals sll, s21 carried by each of the first users ull, ul2 and second users u21, u22 are hereinafter referred to as the first terminal sll and the second terminal s22 respectively. By means of this ap mobile application and a radiofrequency communication protocol chosen from among those existing, the connected mobile terminals sll, s21 are in communication with a remote server 12 with which they exchange data.

[0146] In a non-exhaustive manner, these connected mobile terminals sll, s21 may correspond to smartphones / mobile phones, connected tablets, connected watches, etc.

[0147] In the remainder of the description, in order to explain this embodiment, only a first terminal sll carried by the first user ul 1 and a second terminal s21 carried by the second user u21 are considered. Also, when it is written that a terminal sll, s21 implements a step of the security method 1, it is understood that it is implemented by the mobile application 10 that it contains.

[0148] After launching / starting the mobile application 10, a declaration step EU1, EU2 is implemented during which the first user ul 1 and the second user u21 provide their respective travel means category cl 1, c21 (in other words, the users ull, u21 indicate to the mobile application whether they are traveling on foot, with a cycle, a car, a truck, etc.). Basically, it is through the declaration step EU1, EU2 that the security method 1 categorizes a user ull, u21 as the first user ul 1, or as the second user u21.

[0149] The declaration step EU1, EU2 may be presented in the form of a list displayed on the screens 11, 12 of the terminals s11, s21 and proposing a plurality of first categories of means cl1, c12 of movement and second categories of means of movement c21, c22, c23, c24. The first user and the second user then select their respective means of movement m11, m22.

[0150] Following the declaration step EU1, the first terminal sll implements the geolocation step EG1 and geolocates in real time the position of the first user ull (for example, by means of a GPS satellite geopositioning chip included in the first terminal si 1). The geolocation of the second user u21 allows the mobile application 10 to deduce the typology TG of the geographical area G.

[0151] The second terminal s21 implements, after the declaration step EU2, the geolocation step EG2 to geolocate in real time the position p21 of the first user u21, then the association step EA to associate the virtual security zone z21 with the second user u21.

[0152] Following the geolocation step EG1, the first terminal sll transmits to the remote server 12 during a transmission step El: the position pl 1 of the first user ull, data relating to his first travel category cl 1, and an identifier idl 1 relating to the first terminal sll which will subsequently be used by the remote server 12 to exchange with the first terminal sll.

[0153] Following the geolocation step EG2, the second terminal s21 transmits to the server remote 12 during a transmission step E2: the position p21 of the second user u21, data relating to his second movement category c21, data relating to the radius r21 of the virtual security zone z21, and an identifier id21 relating to the second terminal s21 which will subsequently be used by the remote server 12 to exchange with the second terminal s21.

[0154] If the first terminal si 1 comprises a screen 11, then the security method 1 can comprise a step DM1 of displaying on the screen 11 an online map 111 of the geographical area G in which the position pl 1 of the first user ull is indicated in real time (see [Fig. 9]). It is possible, as illustrated [Fig. 10], that the display step DM1 is implemented after the first terminal si 1 (more precisely the mobile application 10) has received during a reception step Eli' an acknowledgment data item ackl from the remote terminal 12. This acknowledgment data item ackl is sent by the remote server 12 during a transmission step El 1 following a reception step El' during which it has received, from the first terminal si 1, the position pl 1, the data item relating to the first movement category cl 1, and the identifier idl 1.

[0155] The acknowledgment data ackl can be used to indicate to the mobile application 10 that it is connected to the remote server 12.

[0156] If the second terminal s21 comprises a screen 12, then the security method 1 can comprise a step DM2 of displaying on the screen 12 an online plan 121 of the geographical zone G in which is indicated in real time: the position p21 of the second user u21 and his virtual security zone z21, as well as that of the first user u11. Similar to the implementation of the display step DM1 for the first terminal si 1, it is conceivable that the display step DM2 is implemented after the first terminal s21 has received during a reception step E21' an acknowledgment data item ack2 from the remote terminal 12. This acknowledgment data item ack2 being sent by the remote server 12 during a transmission step E21 following a reception step E2' during which it has received, from the second terminal s21: the position p21, the data item relating to the second displacement category c21, the radius r21 and the identifier id21..

[0157] In order for the second terminal to display in the online plan 121 of the second terminal s21 the position pl 1 of the first user ul 1, the remote server 12 can transmit the position pl 1 of the first user ull with the acknowledgment data ack2. In the general case, the remote server 12 transmits to the second terminal s21 the positions pl, p 12 of all the first users pl 1, pl2 present in the geographical zone G.

[0158] The remote server 12, after having received the positions pli, p21 of the two users ull, u21 following the reception steps El', E2', and possibly after having implemented the transmission steps Eli, E21, is configured to implement the ve- Ql verification.

[0159] Although not illustrated in [Fig.10], in the case where the distance between the positions pli, p21 of the two users ull, u21 remains greater than the radius 21, the remote server continues in real time to receive from the two terminals si 1, s21 the updated positions pli, p21 of the two users ull, u21, then to implement the verification step Q1. If the display step DM2 is provided in the security method 1, then the remote server 12, after having received the updated position pli of the first user ull, relays it to the second terminal s21.

[0160] When the distance between the two positions p1, p21 is included in the radius 21, then the remote server implements the danger detection step ED, then sends during a transmission step E3 a danger notification dn to the second terminal s21. Following the reception of the danger notification dn during a reception step E3', the second terminal s21 implements the alert step EW by generating the alert wl.

[0161] In the case where a single sending of danger notification dn is planned, the remote server 12 checks during the verification step Q3 whether or not it has already sent to the second terminal s21 a danger notification dn specific to the first user ul 1. Depending on the result of the verification, the remote server 12 implements the transmission step E3 or not.

[0162] The wl alert generated by the second terminal s21 may, non-exhaustively, take the form of: a text message displayed on the screen, an audible alert, a vibration of the second terminal s21.

[0163] In an alternative embodiment where the second user s21 can himself define the radius r21 of his virtual security zone z21, it is conceivable that the configuration step mentioned later and allowing this definition takes place following the declaration step EU2 and before the association step EA. It is also conceivable in another alternative embodiment that the configuration step takes place in parallel or is included in the declaration step EU2, by being presented in the form of one option among several proposed by said declaration step EU2.

[0164] In one embodiment of the invention, it is conceivable that the declaration steps EU1, EU2 are only carried out during a first launch of the mobile application 10. Indeed, the first user u11 and / or the second user u21 may only have one means of transport m11, m21. In this case, the mobile application 10 allows them to save in memory the category of means of transport c11, c12, c21, c22, c23, c24 that they will have selected during the first launch. In another embodiment, the declaration steps EU1, EU2 are carried out each time the mobile application 10 is launched because it can be considered that the two users u11, u21 have several means of transport m11, m21. belonging to one and / or the other of the two categories of means of transport cil, cl2, c21, c22, c23, c24. Indeed, each of the two users ull, u21 can in a given context, be a first user ul 1, and become a second user u21 in another context (for example: the same user can travel by bicycle or by car).

[0165] [Fig. 11] illustrates an embodiment for which the association step EA is not performed by the mobile application 10, but by the remote server 12. Compared to the embodiment illustrated [Fig. 10], following the declaration step EG2, the second terminal 21 transmits to the remote server 12 during a transmission step E4 its identifier id21, the position p21 of the second user u21 and its second category of means of transport c21. Following the reception of this data during a reception step E4', the remote server implements the association step EA. The position p21 of the second user allows the remote server 12 to deduce the typology TG of the geographical zone G. From the typology and / or the second category of means of transport c21, the remote server 12 determines the radius r21 of the virtual safety zone z21 of the second user u21.

[0166] Following this, the remote server transmits during a transmission step E5: the acknowledgment data ack2, the position pl 1 of the first user ul 1, and the radius r21. Following their reception during a reception step E5', the second terminal s21 implements the display step DM2.

[0167] The detection and signaling of the presence of the first user ul 1 to the second user u21 then takes place similarly to the embodiment described [Fig. 10].

[0168] [Fig. 12] illustrates an alternative embodiment to that of [Fig. 10], for which the additional virtual security zone z21_2 is associated with the second user s21. In this embodiment, the mobile application 10 successively implements the association step EA and the additional association step EA2. Once the two association steps EA, EA2 have been completed, the second terminal transmits to the remote server 12, during a transmission step E22: its identifier id21, the position p21 of the second user u21, the second movement category c21, the radius r21, and the fixed radius r21_2. Upon receipt of this data during a reception step E22', the remote server 12 implements the transmission step E21. Following the reception step E21', the second terminal implements the display step DM2.In this embodiment, it is provided that the positions of the two users u11, u21; the virtual security zone z21 and the additional virtual security zone z21_2 are indicated in the online plan 121 displayed on the screen 12.

[0169] The sequence of all steps Q1, ED, Q3, E3, E3', EW is the same as in the case of the embodiment presented [Fig. 10].

[0170] Detection and reporting to the second user u21 of the presence of the first user 11 in the additional virtual security zone z21_2 also relies on the same principle.

[0171] In other words, the remote server implements the verification step Q2 and checks whether the distance between the positions pli, p21 of the two users ull, u21 transmitted in real time / continuous by the two terminals si 1, ss21 becomes less than or equal to the fixed radius r21_2. Then, it implements the additional danger detection step ED2 if it determines that the distance between the two positions pli, p21 is included in the fixed radius r21_2. If it is intended to send only one additional notification dn2 to warn the second user u21 of the imminent danger, then the remote server implements the verification step Q4. In the case where no additional notification dn2 has been sent, the remote server transmits said additional notification dn2 to the second terminal s21 during a transmission step E6.Upon receipt of the additional notification dn2 during a reception step E6', the second terminal implements the additional alert step EW2 and generates the additional alert w2.

[0172] Just like the alert wl, the additional alert w2 can, non-exhaustively, take the form of: a text message displayed on the screen 12 of the second terminal s21, an audible alert emitted by a loudspeaker of the second terminal s21, a vibration of the second terminal s21.

[0173] [Fig. 13] illustrates the principle of detecting a fall of the first user ul 1 and reporting it to the second user u21 when the security method is implemented by means of the remote server 12, the first terminal si 1, and the second terminal s21. The detection of the fall of the first user ul 1 and reporting it to the second user u21 is made possible on the condition that the reception steps El', E2' have been carried out; that is to say that the remote server 12 has knowledge of the positions p1, p21 of the two users and of the identifier id21 of the second terminal s21.

[0174] The step of detecting a fall FD of the first user is implemented by the first terminal if 1. In one embodiment of the invention, this fall can be detected by an accelerometer that the first terminal comprises, and which interacts with the mobile application 10.

[0175] Following the step of detecting a fall FD, the mobile application 10 of the second terminal implements the alert step FW for which at least one fall alert wf is sent to the first user, then the waiting step Q5 during which it waits for the delay d_act for the first user ull to carry out the stop action act.

[0176] The fall alert may correspond, non-exhaustively: to a text message displayed on the screen 11 of the first terminal if 1, an audible signal emitted by the first terminal if 1, a vibration of the first terminal if 1. In order to notify the first user ul 1 that he must carry out the stop action act, it is possible that the message text message is displayed on a particularly visible background (for example, a red background) or that it flashes. It is possible for the audible signal to consist of an alarm sounding for the entire duration of the d_act delay. It is also possible for the alert to consist of an alarm combined with the display of an alert text message.

[0177] The stop action d_act may correspond to an interaction of the first user ul 1 with the screen 11 of the first terminal si 1 and / or of the mobile application 10.

[0178] If the stop action d_act is not carried out, then the first terminal si 1 implements a transmission step E7 during which it transmits to the remote server 12 a fall reporting alert swf. When it receives the fall reporting alert swf during the reception step E7', the remote server 12 implements the verification step Q6 to check whether the distance separating the positions pl 1, p21 of the first user ul 1 and the second user u21 is less than or equal to the reporting distance given from the position pl 1 of the first user ul 1. If this is the case, then the remote server 12 implements a transmission step E8' during which it transmits to the second terminal s21 the fall reporting alert swf and the position pl 1 of the first user ul 1, causing the second terminal s21 to then carry out the fall reporting step FS to notify the second user u21 of the fall of the first user ul 1.

[0179] When it reaches the second user u21, the fall reporting alert swf may take, but is not limited to, the form of a text message displayed on the screen 12 of the second terminal s21, an audible alert emitted by a loudspeaker of the second terminal s21, or a vibration of the second terminal s21. The position pl 1 of the first user is also indicated on the online plan 121 displayed by the screen 12 of the second terminal.

[0180] In the embodiments for which the first user ul 1 has a first terminal si 1, it is conceivable that the latter can enter into the mobile application 10 means of contact (for example, telephone numbers, electronic addresses) making it possible to contact people close to the first user ul 1 (for example, family members). The mobile application 10 is then configured to use these means of contact and transmit to these said close people the fall reporting alert swf and the position pl 1 of the first user ul 1 if the latter has not carried out the stop action d_act during the waiting step Q5, in addition to reporting his fall to the remote server 12.

[0181] With reference to [Fig.14], in one embodiment of the invention, there is proposed for the at least one second user u21, u22 an electronic device 21 (contained in a physical housing) arranged on his second means of movement (inside the passenger compartment or outside but always visible to the second user); this electronic device 21 comprising a computer program 20 having for role of executing the securing method 1. The electronic device 21 is configured to be at least in communication, by means of a wireless communication protocol, with a warning system 211 which can be installed inside or outside the second means of movement m21, m22. It is also conceivable that the electronic device 21 has at least one connection port 22 to physically connect the warning system 211 by means of a wired connection. The warning system is configured according to two states: an off state during which it is inactive, and an operating state during which it is configured to warn the at least one second user u21, u22 at least of the proximity of at least one first user u11, u21.

[0182] In the remainder of the description, for greater convenience, when it is indicated that the electronic device 21 implements a step of the security method 1, it is understood that it is the computer program 20 which implements said step. Also, it is considered that the at least one first user u11, u12 comprises the first user u11; and that the at least one second user u21, u22 comprises the second user u11.

[0183] A first embodiment involving electronic device 21 for signaling to the second user u21 the proximity of the first ull is illustrated [Fig. 15]. It is considered that the first user ull has a first terminal si 1. The first terminal si 1, via the mobile application 10, and the electronic device 21 are in communication with a remote server 12.

[0184] At the start of the securing method 1, the warning system 211 is in the off state.

[0185] The first terminal implements the steps of declaration EU1, geolocation EG1, and transmission El similarly to the embodiment presented [Fig.10].

[0186] The electronic device 20 first implements the geolocation step EG2 and the association step EA. The radius r21 of the virtual security zone z21 of the second user is at least determined from the typology TG of the geographical zone G, deduced by the electronic device 21 from the position p21 of the second user u21, in the case where the electronic device 21 is provided as a standard model independent of any consideration of the second category of means of movement c21, c22, c23, c24. In the case where specific models adapted to all second categories of means of movement c21, c22, c23, c24 are proposed; then the second category of means of movement c21, c22, c23, c24 is taken into consideration in determining the radius r21.

[0187] Following the association step, the electronic device 20 implements a transmission step E30 during which it transmits to the remote server 12: the position p21 of the second user, the radius 21, and an identifier id-dis making it possible to identify it with from the remote server 12.

[0188] Following the reception step El' and a reception step E30', during which the remote server receives the data indicated above, the server implements the transmission step Eli. As seen above, after having received the acknowledgment data ackl during the reception step EU', the first terminal sll implements the display step DM1.

[0189] Optionally, it is conceivable that the remote server 12 implements the transmission step E31 if the electronic device 20 is designed to be able to be physically connected to an external screen (i.e., a screen not being included / integrated in the electronic device 20), during which it transmits to the electronic device 20 the position pl 1 of the first user ul 1 and the acknowledgment data ack2. Once received during a reception step E31', the electronic device 20 performs the display step DM2: the second user u21 can then view on the external screen his position p21, his virtual security zone z21, and the position pl 1 of the first user ul 1. Otherwise, the transmission step E31 is not performed since the electronic device 20 does not allow the display step DM2 to be performed.

[0190] The rest of the implementation of the security method is relatively similar to that of the embodiment presented [Fig. 10]. The remote server 12 continuously receives the positions p1 1, p21 of the users from the first terminal s11 and the electronic device 20, and applies the verification step Q1. In the case where the first user ul 1 enters the virtual security zone z21 of the second user u21, the remote server 12 implements the danger detection steps ED and verification steps Q3. If no danger notification dn has already been transmitted to the electronic device, then the remote server 12 implements a transmission step E32 during which said danger notification dn is transmitted to the electronic device 20.

[0191] Following receipt of the danger notification dn during a reception step E32', the electronic device implements the alert step EW during which it transmits an activation signal sstart to the warning system 211, which then passes from the off state to an operating state during which it generates the alert wl to warn the second user u21 of the danger.

[0192] The warning system 211 may correspond in different embodiments of the invention to an audible warning device (such as a siren or a device emitting a brief and possibly repeated audible signal), or a light warning device (the wl alert being an audible alert), such as a rotating beacon (the wl alert being in this case a visual alert). It is conceivable that the warning system 211 is a combination of these two types of warning device so that the wl alert is both visual and audible.

[0193] In one embodiment of the invention, the electronic device 21 is configured to send, after an operating delay following the sending of the activation signal sstart to the warning system 211, a deactivation signal to the warning system to cause it to switch from the operating state to the off state.

[0194] In an embodiment involving the electronic device 20, and which is not illustrated, the electronic device 20 is configured to implement, following the association step EA, the additional association step EA2 consisting of associating the additional virtual security zone z21_2 with the second user u21, and the fixed radius r21_2 of which is transmitted to the remote server 12.

[0195] Thus, the remote server 12 implements the additional danger detection step ED2 when it determines during the verification step Q3 that the distance between the positions pl 1, p21 of the two users ul 1, u21 is less than or equal to the fixed radius r21_2. The remote server 12 then transmits to the electronic device 20 the additional notification dn2, provided that it has not already transmitted one to it.

[0196] Upon receipt thereof, the electronic device 20 implements the additional alert step EW2 so that the second user u21 is warned of the imminent danger by the additional alert w2. The additional alert w2 is also generated by the warning system 211. It is therefore of the same nature as the alert wl (visual, audible, visual and audible, etc.). Similar to the alert wl, the additional alert w2 is generated when the electronic device 20 sends an additional activation signal to the warning system 211 so that the latter again switches from the off state to the operating state, the warning system 211 then remaining in the operating state for a predetermined additional operating time.

[0197] In another embodiment not illustrated and involving the electronic device 20, the association step EA, and possibly the additional association step EA2, are implemented by the remote server 12. In this case, the electronic device 20 only transmits to the remote server its identifier id-dis and the position p21 of the second user u21.

[0198] In another embodiment, the remote server 12 is not used, and the electronic device 20 is capable, via a radiofrequency communication protocol, of locating the first terminal in the geographical zone G and of exchanging with its mobile application 10. The mobile application then transmits to the electronic device the position pl 1 of the first user ul 1. After having previously implemented the geolocation step EG2 and the association step EA, the electronic device implements, following the reception of the position pl 1 of the first user, the verification step Q1. If the position pl 1 of the first user is not included in the virtual security zone z21, then the electronic device waits to receive a new position pl 1 of the first user from the first terminal before implementing the verification step Ql again. If the position pl 1 of the first user ul 1 is included in the virtual safety zone z21, the electronic device 20 successively implements the danger detection step ED and the alert step EW.
