Description

The invention relates to the field of devices for assisting a person victim of a health problem, a home or professional accident, or more generally, a person. facing a situation likely to present a vital danger and / or for which we seek to contain the damage caused by a disaster or disorder, while reassuring the person in distress, or his entourage or witnesses. The invention applies to professionals and individuals. One of its major objectives is to better report the scene of a disaster in order to facilitate, and thus accelerate, the relevant relief intervention on site.

In the remainder of the document, the invention will be described in a preferred but non-limiting manner in the context of a first aid dispensation. However, it could be applied to any other situation requiring effective alert signaling requiring rapid third-party intervention.

Because every minute counts for a successful relief operation, accurate and reliable identification of the whereabouts of a person in distress is fundamental. Relief services are continually modernizing with navigation systems or centralized communications links. However, it is considered that one-third of relief interventions face a real difficulty of localization, thus slowing down in a significant way, and thus detrimental, the arrival of relief on site, causing sometimes irreversible consequences for people in distress or their surroundings, consequences that could have been contained by a more prompt intervention.

Indeed, many streets or paths are not always mapped, and therefore unknown, some satellite navigators. Rescue personnel must be guided by imprecise cartographic maps. Sometimes even, no number is indicated on the fence of a house or a place of residence. Said rescue personnel are then forced to stop at the level of multiple mailboxes to read the names of the residents, when the latter is informed. Fire trucks or ambulances can thus pass several times in front of the scene of a disaster without being aware of it. To limit this inconvenience, the rescue personnel must sometimes rely on the neighborhood to orient themselves or to make a counter-appeal to ask, if possible, that a possible witness can appear near the incident and guide said rescue personnel.

Other characteristics and advantages will appear more clearly on reading the description which follows and on examining the figures which accompany it, of which: FIGS. 1A, 1B and 1C illustrate respectively front, side and side views; section of a non-limiting example of a front face of a device for emitting a light alert according to the invention; FIGS. 1D and 1E describe respectively front and back perspective views of such a non-limiting example of a front face of a device for emitting a light alert according to the invention; FIG. 1F shows a back view of a non-limiting example of a rear face of a device for emitting a light alert according to the invention; FIGS. 2A, 2B and 2C respectively illustrate front, side and back views of a nonlimiting example of an alerting trigger object according to the invention and arranged to control a device for emitting a light alert. also according to the invention; FIGS. 3A and 3B describe respectively a profile and a top view of a light beam delivered by a nonlimiting example of a device for emitting a light alert according to the invention, affixed to a substantially vertical support; - Figure 4 shows schematically and simplified, an alert management system according to the invention; FIG. 5 describes, in detail, the means implemented by the elements of a system according to FIG. 4.

FIGS. 1A and 1D describe a front view of a non-limiting exemplary embodiment of a front face of a device for emitting a light warning according to the invention. The same device 10 is described in profile in FIG. FIG. 1F describes, for its part, an example of a rear face of such a device 10.

The latter has in fact a housing 19 of substantially circular shape or in the form of a drop of water advantageously reversed.

Such a housing 19 may comprise two half-shells 19F and 19B, as indicated in particular and respectively in FIGS. 1D and 1F of said device 10. The two half-shells 19B and 19F can cooperate mutually according to any mechanical connection to alternatively allow and / or or prohibit any access to the internal elements of the device 10. By way of non-limiting example, the half-shell 19F, constituting the front face of a device 10, may comprise one or more projections or bayonets 181, arranged to cooperate, according to a sliding connection, with a partially circumferential groove 191, made in the body of the half-shell 19B which forms the rear face of said device 10.

As indicated in FIG. 1A, the front face of a device for emitting a light warning according to the invention comprises a large opening closed by a translucent lens 140, for example a Fresnel-type lens or the like, of a system optical device 10 having an optical axis AO, said optical axis AO being substantially normal to a virtual plane described by the front face of the device 10, therefore, ultimately, substantially normal to the outer surface of a support against which the rear face said device 10 will be fixed. By way of example, to constrain the light beam delivered by such a device 10, the housing 19 may have two protuberances 151 and 152 in the form of "crescents" respectively on either side of said lens 140. protruding further provide protection to the lens 140 against possible shocks likely to be struck on the front face of the housing 19 of said device 10. When a device 10 is affixed and fixed correctly on a substantially vertical support, it is positioned substantially as shown in Figure IA or 1D. The protuberances 152 and 151 "thus" encase the lens 140, respectively above and below it. The unobtrusive portion of said lens 140 thus substantially describes a rectangle, or an oblong shape such as an ellipse, possibly slightly curved in a vertical plane and parallel to the outer face of the support of the device 10, and of longitudinal axis AL substantially horizontal and parallel to said vertical plane, as shown in Figure IA.

The housing 19 may comprise or cooperate with means for locking and / or unlocking the two half-shells 19B and 19F, in order to prevent unauthorized or malicious access to the internal elements of the device to emit a light warning 10, by making the two half-hulls joined to each other. Such means can cause a reversible or irreversible locking according to the desired exploitation. Furthermore, a device for emitting a light alert according to the invention is designed to be positioned on an enclosure or external support. It will therefore be subjected to bad weather. The half-shells 19F and 19B may, for this reason, advantageously cooperate with each other via a seal, so that the housing 19 is perfectly sealed once the half-shells 19B and 19F assembled.

The half-shell 19B, corresponding mainly to the rear face of the device 10, is advantageously designed to be affixed and fixed against a substantially flat support, for example a wall. As indicated in FIG. 1F, such a device can be fixed on a support by means of screws or any other equivalent material, via openings 190 made in the half-shell 19B. The latter could alternatively or complement, include supports or pastes not shown in Figure 1F. Said half-shell 19B could also include one or more other optional openings also not described to serve as a cable-pass, if it is desired, for example, to use an external power supply for the device to emit a light warning device 10 or to make it communicating via a wired link, for example Ethernet or equivalent. According to the example described with reference to FIGS. 1A to 1F, the half-shell 19F can advantageously support the main electronic elements of said device 10. Alternatively, the half-shell 19F could carry only a subset of a optical system, for example the lens 140, or no element, such as a simple protective cover. The cross-sectional view, illustrated by way of non-limiting example in FIG. 1C, describes a second subset of the optical system of such a device 10 in the form of a reflector 130 whose joint function with the lens 140, or more generally the optical system of said device 10, consists, when the light source of said device 10 is actuated, to diffuse a characteristic light beam and easily recognizable with respect to other light beams delivered by separate systems, such as for example a commercial sign , an intrusion detection device, etc.

Said FIG. 1C presents a light source 11 comprising a pair of light-emitting diodes 110 and 120 of a power advantageously chosen to be between one and five watts per diode. The invention can not however be limited to these only examples of light sources or powers. Other technologies could be used alternatively or in addition to light emitting diodes. These will be preferred especially if a stand-alone or emergency power supply is adopted, in the form of one or more electric batteries, for example of the "lithium battery" type or any other equivalent equipment. The housing 19, for example, the half-shell 19F according to the example described in Figure 1E, may comprise one or more slots 180 arranged to accommodate one or more electric batteries. Indeed, the low power consumption of a light emitting diode is a valuable asset to minimize the maintenance actions to replace or recharge the batteries, compared with other light sources that consume more energy such as gas discharge bulbs, such as tubes fluorescent lamps, sodium vapor lamps or metal halide lamps, or even incandescent halogen lamps. FIGS. 1A to 1F do not describe other elements or electronic components of a device for emitting a light warning device 10 according to the invention. A detailed description of these will be made later in connection with Figure 5, in particular. Finally, Figure 1E illustrates that openings may be made in the rear wall of the half-shell 19F. Thus, for example, apertures 160 may make it possible to fasten the optical system or certain electronic elements to the half-shell 19F by means of screws; other optional windows, such as apertures 170, may be used as cable glands.

One of the main functions of a device for emitting a light alert according to the invention lies in its power of diffusion of a perfectly visible light beam and recognizable by the greatest number.

Such a device for emitting a light alarm 10, like that described in FIGS. 1A and 1B, is arranged to be affixed against a substantially planar and vertical support S, as indicated in FIG. 3A. To maximize its effectiveness, it will be fixed on said support, so that the unobtrusive portion of the lens 140 of said device 10 substantially describes a rectangular projection or oblong in a substantially vertical plane and parallel to the outer face of the support S, whose length of said rectangle is substantially horizontal. The central point of the lens 140 is crossed by the optical axis AO of the optical system constituted by said lens 140 and the reflector 130. Such an optical axis AO is substantially normal to the plane substantially described by the area of the wall PS of the support S against which is fixed said device 10. Under the combined action of the reflector 130, the lens 140 or optional protuberances 151 and 152 of the housing 19 of a device 10 described in connection with Figure IA, the value of the sector SAT angular described by the light rays L produced by the light source of said device 10 is advantageously less than a predetermined value, for example thirty degrees, in a transverse plane, vertical and normal to the wall PS of the support S. Indeed, for to limit unnecessary light disturbances that could be caused by light scattering L in too vertical directions (ie towards the sky or the ground), the optical system of the device 10 and / or the front face of said housing 19 thereof may even advantageously be designed and dimensioned to limit said SAT angular sector to twenty degrees, that is to say ten degrees on either side of the axis optical AO.

On the other hand, it is particularly interesting to broadcast as widely as possible, that is to say to approach the 180 degrees, the light L in order to transmit the light signal to the greatest number, as indicated by the 3B which illustrates, seen from above, the device 10 for emitting a light alert according to the invention. Thus, the reflector 130 and the lens 140 of the optical system will respectively and mutually arranged so that the light rays L, produced by the light source 11 of said device 10, describe an angular sector SAL of a value greater than one hundred and thirty-five degrees ideally close to one hundred and eighty degrees, along a longitudinal plane normal to said transverse plane along the optical axis AO of said optical system. When the device 10 is positioned correctly, such a longitudinal plane is substantially horizontal, if the outer wall PS of the support S is substantially vertical.

In addition, such an optical system of a device 10 for emitting a light alert according to the invention may advantageously be arranged so as to form or comprise a collimator of the light rays produced by the light source 11. The light beam L thus "collimated ", That is to say whose rays are substantially made parallel in a transverse plane, is more perceptible and powerful. By way of nonlimiting example, if a light source 11 having four light-emitting diodes is chosen, it is possible to generate, using a suitable optical system, a light beam visible more than two kilometers away.

The light source may be chosen or controlled to emit light rays in one or more colors determined in order to meet territorial norms and restrictions. A white light beam may be preferred or, alternatively, blue, red, yellow, etc. The lens 140 may optionally include a filter for coloring said beam instead of or in addition to the light source.

Let us now study, in conjunction with FIG. 5, the functional architecture, beyond the optical system and the housing that compose it, of a device for emitting a light warning device 10, as described above in connection with FIGS. IA at ΙΕ, 3A and 3B. To control, that is to say activate or deactivate, a light source 11, according to a specific lighting protocol, a device for emitting a light warning 10 comprises a processing unit 12, in the form of a microcontroller or a microprocessor associated or comprising a controller 15 of said light source 11. The latter is responsible for translating an actuation command of said source produced by said microcontroller into an electrical signal sufficient to actuate said source. For the sake of simplicity, hereinafter we will discuss processing unit 12 for denominating in an undifferentiated manner the elements referenced 12 and 15 in FIG. 5. Such a processing unit 12 is associated, that is, comprises, or cooperates via an electric bus with a program memory 13 responsible for recording one or more computer programs. Such a PI computer program consists of a set of program instructions that can be interpreted or executed by the processing unit 12. Such execution or interpretation of instructions causes the implementation of a certain lighting method or protocol. in response to a trigger event. Such an event may result from the receipt of a message triggering alarm Ma by means of communication 16 or 17 cooperating with said processing unit 12. We will study later that such a message Ma can be developed and issued by a third party alerting triggering object cooperating with said device 10 through a communication network RI or R2, wired or wireless via a communication protocol without contact proximity, such as, without limitation, Bluetooth or Wi-Fi Fi. The communication means of the device 10 will therefore be adapted or arranged to satisfy the desired communication modes. The implementation of the lighting method or protocol can be parameterized by means of data whose values can advantageously be recorded in a second data memory 14, within possible data structures. By way of nonlimiting example, an advantageous and preferred lighting protocol may consist in triggering the light source 11 in the form of a series of a predetermined number of flashes. The term "flash" means a brief operation of a predetermined duration of the light source followed by a deactivation period of a second predetermined duration. Thus, a lighting protocol may consist in emitting a light signal in the form of a plurality of consecutive series of three actuations of the light source, with a unit duration of half a second, also spaced by a half -second, an activation of a frequency of two Hertz. Two consecutive sets of three flashes can be separated by a duration of one to two seconds. Any other lighting protocol could, alternatively, be implemented by the processing unit 12. Like the program memory 13, the data memory 14 may be, for all or part, electrically erasable so that to be updated. Generally, a section of said data memory 14 is not erasable or is protected by a security mechanism to record in particular the value of a unique identification data item 110 characterizing a device for emitting a light alert 10 according to the invention particularly with regard to peers. Such a data memory 14 may furthermore comprise other data structures for recording, for example, a secret or a secret and / or public key making it possible to check the signature of a sender of a message, and / or to decode a received message. Conversely, such a secret or key may allow the processing unit 12 to develop a message encoding possibly encrypted data and / or signed using a data stored in said data memory 14 to the outside world . The memories of programs 13 and data 14 may each consist of one or more entities, or even constitute one and the same physical entity.

The various elements 13, 14, 15, 16, 17 cooperate with the processing unit 12 by means of data bus and / or address represented by double arrows in FIG. 5. To enable the operation of a device 10 to emit a light alert according to the invention, the latter requires a source of electrical energy. This source can be external, the electricity being conveyed by cable or induction. Alternatively or additionally, to provide a backup power supply and provide a break in the electrical network, a device 10 according to the invention may comprise an autonomous power supply source 18 delivering the electrical energy necessary for the operation of said device 10 According to the chosen embodiment of such a device 10, the processing unit 12 can be arranged or adapted to know the level of electrical energy remaining in the power supply source 18. We will see later that the unit processing 12 can be programmed to encode a data whose content characterizes such a remaining energy level in the form of a diagnostic message Md and trigger the transmission of said diagnostic message Md by the communication means 16, 17 to destination of the outside world, as soon as said remaining electrical energy level is below a predetermined threshold, the value of which may be defined by a parameter stored in the data memory 14 or programs 13. As a variant or in addition, the processing unit 12 can modify the lighting protocol according to the level of electrical energy remaining, for example by spacing each series of flashes of increasing duration to save the internal power source 18 when it begins to dwindle.

FIGS. 4 and 5 respectively, in simplified or detailed ways, illustrate different embodiments of a light alert management system according to the invention, depending on whether one chooses a simple embodiment or more sophisticated.

According to a first embodiment, which we may qualify as "autonomous" or by "stand-alone" anglicism, a first system, in accordance with the invention and described in FIG. 4, may consist of equipping a HA residence. a device 10A for emitting a light alert according to the invention, for example a device similar to the device 10 described above in connection with FIGS. 1A to 1F and 5. The processing unit 12 of such a device 10A is arranged to actuate a light source 11 in response to the interpretation of an alarm triggering message Ma previously received by the communication means 17. In the non-limiting example of application described in Figure 4, the system equipping the HA dwelling or residence comprises a device 10A in communication, via a wireless communication network RI implementing a Bluetooth or Zigbee wireless proximity communication protocol, with an object alarm release 20A in the main form of a push button with a function of communication and interpretation of messages issued by the device 10A. Such a preferred embodiment, although not limiting, of such an object 20A is described in FIGS. 2A to 2C.

To facilitate the recognition by any resident of this object among others possibly present in the place HA, the external appearance of the object 20A, illustrated by way of example in the form of an object 20 in FIG. 2A, resumes the features of the device to emit a light alert 10 described in connection with FIG IA. Any other exterior appearance could alternatively be retained. FIG. 2A thus shows, seen from the front, an example of an alarm-triggering object 20 comprising a push-button 21 movably mounted within a case 29. The latter has, for identification purposes, protuberances 24 and 25 evoking the protuberances 151 and 152 of the housing 19 of a device 10 described in Figure IA. The protuberances of the housing 29 are of course optional. FIG. 2B describes such an alert trigger object seen in profile and FIG. 2C shows the latter seen from the back. Like the half-shell 19B, the rear face of the housing 29, the latter may comprise, like the housing 19, two half-shells, may have openings 23 to allow to fix the trigger object alert 20 on any substantially planar support.

Such an alerting triggering object 20 comprises a clean processing unit, that is to say a microcontroller or microprocessor programmed with recorded program instructions for example, in a program memory cooperating with said unit. processing said alert trigger object 20.

The visible portion of the push button 21 may include any indication necessary for its identification by a potentially distressed person. It can be translucent to let a light generated by a first light source internal to the object 20 and driven by the processing unit thereof be filtered. Said light source may be triggered in response to actuation of the push button 21 to confirm to the person who actuated said alert triggering object 20 that his request for assistance has been taken into account by said triggering object. 20. The processing unit of this object may also be arranged to trigger a second light source, or more generally any means capable of emitting a light signal and / or sound perceivable by the human, in response to the receipt of a diagnostic message Md possibly issued by a device for emitting a light alert according to the invention, for example translating a low battery level or more generally any risk of loss of service of said device, such as a loss of ability to communicate, a failure of the light source thereof, etc. The nonlimiting example described in FIG. 2A presents an alarm triggering object comprising a second light source 22, in the form of a light waveguide describing a circle surrounding the pushbutton 21 and emitting a light. a characteristic color. Any other configuration could, alternatively or in addition, be implemented to deliver such information.

As indicated in FIG. 4, the dwelling HA is equipped with an alert management system thus comprising a device for emitting a light alert 10A cooperating via a wireless communication network of proximity RI with a trigger object of FIG. alert 20A. The two devices exchange information, in particular, by means of messages Ma and Md respectively to activate the activation of the light source of the device 10A thus preventing the outside world from a distress or an ongoing disaster, or one actuation. the second light source of the alarm triggering object 20A signaling a risk of imminent loss of service of said device 10A.

FIG. 4 also shows an alert management system according to the invention according to which an additional message Maq, which can be developed and transmitted, to said device 10A, the alerting trigger object 20A to translate an acknowledgment of the warning and thus cause the deactivation of said light source of the device 10A by the processing unit of the latter. Such a Maq message thus translates the end of the signaling of a distress or a disaster, for example as a result of a trigger error or following the arrival of emergency personnel. According to this embodiment, the processing units of the triggering object 20A and the device 10A are arranged accordingly for respectively developing and interpreting such a message Maq.

As mentioned above, a secret and / or a key shared between the two devices and stored in respective data memories can be used to encrypt and / or sign messages Ma, Md or Maq so that only said equipment 20A and 10A are able to exploit such messages Ma, Md or Maq. Such sharing of secrets or other data necessary for this purpose arises from a preliminary step of pairing the equipment, performed during the installation of the system or after a maintenance operation of said system.

Thus, other alert management systems according to the invention can coexist in a restricted area without interfering with one another. Thus, Figure 4 describes a second housing HB with a second alert management system similar to that fitted to the place HA. The only difference lies mainly in the embodiment of the triggering object 20B cooperating with a device for emitting a light alert 10B according to the invention. Indeed, unlike the device 20A similar to the object 20 described in FIG. 2A, the triggering object 20B advantageously consists of an intelligent mobile phone adapted to be able to transform itself into an electronic object capable of transmitting an alarm triggering message. For this, the invention provides that a suitable application can be designed to be installed in a memory of said telephone 20B to allow its user to operate the device 10B. Such an application could, in addition, be installed in any other electronic object, possibly via a few software adaptations, for example a touch pad, a personal computer, etc. According to the example described in connection with FIG. 4, the communication network RI ensuring the cooperation between the equipment 20B and 10B could be wireless, via the Wi-Fi protocol, or wired, or even identical to that of the system equipping the HA dwelling. An object 20B could also, thanks to the application or computer program installed in its memory, restore a perceptible alert by its user in response to a diagnostic message Md issued by the device 10B. Such an object 20B could also issue a message Maq to cancel a nuisance and untimely triggering of a distress alert.

A light alert management system according to the invention according to this first "autonomous" embodiment provides a particularly effective and relevant response to the current problem of insufficient location of a disaster for emergency personnel. They can be more prompt at the scene of a disaster and thus limit the damage. Such an alert management system also reassures the person in distress because it knows that his entourage will also be able to perceive the light signal and possibly relay his distress call.

Figure 4 also illustrates a second embodiment of a system according to the invention more sophisticated. Indeed, the invention provides, in addition to the issuance of a simple light alert, although it is particularly effective, a device for issuing such a light alert can automatically inform third parties, for example relatives or a rescue center, by a second communication channel complementary to the previous one.

For this, and in connection with FIG. 5, the processing unit 12 of such a device 10 for emitting a light alarm may advantageously be arranged to also: construct an Ms distress message encoding a data whose unique and dedicated value characterizes the device to emit a light alert 10; then triggering the transmission of said distress message Ms by the communication means 16, 17 to the outside world, as soon as the light source 11 is actuated.

Encoding such a unique value characterizing a particular device, such as the device 10A or 10B described in connection with FIG. 4, allows an electronic device, arranged to interpret such a distress message Ms, to identify the device. device emitting said Ms distress message and thereby, as we shall see, the scene of a disaster or distress. Such encoding can result in the integration, in the body of said Ms message, of the value of a piece of data such as a device unique identifier 110, said value possibly being pre-recorded in the data memory 14 thereof. . Such an encoding may alternatively result in the signature of such an Ms message with the aid of a key or a secret proper to said device, the body of said Ms message essentially comprising, in this case, only a characteristic header typing said Ms message as a distress message.

According to this second embodiment of an alert management system that we will describe as a "connected" system to differentiate it from the "autonomous" system previously studied, the invention provides that the main recipient of such a distress message Ms can be a dedicated and innovative application server, which we will call "alert management server" specific to 1'invention.

Figures 4 and 5 describe such an alert management server 30 according to the invention. This comprises a processing unit 31, first storage means or a data memory 32. It further comprises communication means 34 enabling said server 30 to cooperate with the outside world via a long-range communication network of the Internet type, LoRa or SigFOX, or any other equivalent communication network and advantageously adapted to connected objects. Such an alert management server 30 may furthermore comprise a program memory 33 for storing any computer program P2 whose program instructions, interpretable or executable by the processing unit 31, make it possible to automatically adapt the operation of a conventional server so that it becomes an alert management server 30 according to the invention. The different electronic components 32, 33, 34 of such a server 30 cooperate with the data bus processing unit 31 and / or address represented by double arrows in FIG.

The data memory 32 may be partially or fully electrically erasable to be updated. Generally, a section of said data memory 32 is not erasable by construction, or is protected against such erasure by a security mechanism. Such a memory section saves in a perennial manner, in particular the value of a unique identification data item 130 characterizing a particular light management server 30 with regard to possible even application servers. Such a data memory 32 may further comprise one or more data structures for storing, for example, a secret or a secret and / or public key making it possible to check the signature of a sender of a message received by the sending means. communication 34 and / or to decode such a message. Conversely, such a secret or such a key may allow the processing unit 31 to develop a message encoding possibly in the body thereof encrypted data and / or signed using a data recorded in said Data memory 32. Program memories 33 and data memories 32 may each consist of one or more physically separate entities, or even constitute one and the same physical entity.

An alert management server 30 according to the invention is characterized in particular by the fact that its processing unit 31 is arranged or adapted, for example by the loading into memory of programs 33 of a suitable application program P2. The processing unit 31 is thus made capable of interpreting a distress message Ms as soon as it is received by the communication means 34 of said server 30. According to the invention, such a distress message Ms is transmitted by a device to emit a light alert, such as the device 10 described in detail in FIG. 5, or such as one of the devices 10A and 10B presented previously in connection with FIG. 4.

Furthermore, the communication means 16 of such a device for emitting a light alarm are in this case also adapted to send an Ms distress message via a long-range communication network of Internet type, LoRa, SigFOX, or equivalent, to an alert management server 30 according to the invention. The interpretation of such a distress message Ms by the processing unit 31 of such a server 30 mainly consists in deducing a data whose unique and dedicated value 110 characterizes the transmitting device 10, 10A or 10B of said message Ms .

The data memory 32 of such a server 30 furthermore comprises a data structure PP1, PPn, associated with each device for transmitting a light alert 10 according to the invention and known from said server 30. Thus, the structure PP1 can be associated with the device 10A illustrated in Figure 4 and the data structure PPn to the device 10B also present in Figure 4.

Such a data structure PP1 or PPn comprises a plurality of fields, among which a field comprising the value of a unique identifier or identifier of a device for emitting a specific light alert, or any value of a characteristic quantity of a such device. In connection with FIG. 5, the data structure PP1 may, for example, comprise a field recording the value of the unique identifier 110 of the device for issuing a lightning alarm 10. Associated with this first field, other fields may record informative data associated with a natural person generally residing in the place of residence equipped with an alert management system comprising the device 10. Such information may consist of an address, a suggested or preferable itinerary, any coordinate of location of said place of residence, a surname designating the natural person, or even additional data, for example in connection with a medical file, which can give valuable assistance to rescue personnel. By way of example, such complementary data may describe one or more allergies or any physiological anomaly related to said natural person. Such a structure PP1 may further comprise contact details of a rescue center located near said place of residence, or even telephone numbers or emails of one or more relatives.

After having decoded a distress message Ms to identify the device 10, 10A or 10B having transmitted it, the processing unit 31 of a server 30 in accordance with the invention implements a step to search among the structures of data PP1 to PPn stored in the data memory 32, a data structure associated with the identifier 110 derived from a received Ms message, i.e., for example, the data structure which would include a recording field the value of said identifier 110. If no data structure associated with this identifier exists within the data memory 32, the Ms message may be ignored, or even possibly propagated, so that another peer application server can interpret it. . In the opposite case, the data structure, in this case the structure PP1, is read by the processing unit 31, in order to produce an emergency call message MsT intended for a call server 60 designed to interpret such an MsT message. Such a call server 60 is thus provided for translating a request in the form of such an MsT message into an As call, of a telephone nature, or in the form of a message or an e-mail addressed to a user. destination via a communication network R3 adapted, depending on the type of contact details of said recipient conveyed in said message MsT. Such a call As can be addressed to a 40-1 emergency center or to a third person via a mobile phone 40-2. Such a call may relate various information taken from the MsT message developed by the server 30, such as the date and time of the distress call, the name of the person in distress, the address of the place of residence of the incident. Thus, the processing unit 31 of a server 30 will advantageously be designed to develop an MsT message including the current stamp during the development of said MsT message and all or part of the data specific to the natural person read in the structure of PP1 data including the identifier or contact details of a recipient 40, a 40-1 emergency center or a close 40-2.

When a single emergency center 40-1 can not be contacted, the invention provides as a variant that the value of the identifier or contact coordinates of such a recipient can be entered in the data memory 32 of said server. management of an alert 30, within a dedicated data structure instead of a data structure PP1 to PPn associated with a natural person. The invention further provides that a distress message Ms, produced by a device for emitting a light alarm such as the device 10 illustrated in FIG. 5, may comprise, in addition to a value characterizing the device 10 transmitting said message Ms such that the identifier 110, a secondary identifier designating a resident among a plurality of residents known to evolve in the place of residence equipped with said device 10. This variant can be made possible by associating such a secondary identifier with an alarm-triggering object 20- 2, for example an object such as object 20 described in connection with FIG. 2A, which implies that such an object 20-2 is dedicated to a particular person. It can also be made by adapting an alert triggering object when it consists of a 20-1 smart mobile phone or other equivalent equipment. Indeed, the invention provides in this case, that the application adapting such an alert trigger object 20-1 can provide a graphical interface and / or sound to designate the person in distress among the plurality of residents. According to this advantageous embodiment, the processing unit of the triggering object 20-1 is adapted to integrate such designation information into the alert triggering message Ma. In the same way, the processing unit 12 of the device 10 cooperating with the object 20-1 is adapted to interpret such an enriched Ma message and to relay said designation information of the person in distress in the distress message Ms, in turn transmitted to the management server of an alert 30. The latter is also adapted to propagate the designation information in an emergency call message MsT addressed to the call server 60. Finally, the rescue personnel can refine its action via the designation information drawn of the emergency call As elaborated by the call server 60.

In addition to a precise designation of a person in distress, the invention provides for completing a distress message Ms, so that it can convey additional information in connection with a measurement delivered by a sensor 50 cooperating with a device for to emit a light alert 10 according to the invention. Thus, as described in FIG. 5 or the simplified description of the alert management system equipping the dwelling HB illustrated in FIG. 4, an alert management system may comprise a sensor 50 arranged and positioned to measure a magnitude. in connection with the environment of the device for issuing a light alert 10 or 10B. Such a sensor 50 may be incorporated in the device 10 or 10B or cooperate, by wired or wireless RI, with said device for emitting a light alert via a message Mc emitted by said sensor. In this way, the processing unit 12 of said device can add contextual information related to the environment of a person in distress in the distress message Ms, which it can send in response to a triggering message Alert Ma As with the optional information of designation of a person, this contextual or environmental information may be propagated to a rescue center by the alert management server 30 and the call server 60, also adapted and respectively accordingly. Such information may be particularly useful. For example, when a resident, feeling close to unconsciousness, activates a warning triggering object ΣΟΙ, 20-2 or 20B, the loss of consciousness being induced by an excessive presence of carbon monoxide or any other gas harmful, said presence being measurable by said sensor 50, this additional information may be crucial for emergency personnel preparing its intervention in response to the call As produced by an alert management system according to the invention. Alternatively, such a sensor 50 could non-exhaustively measure a rate of smoke particles or excessive temperature, so many complementary and valuable elements to inform emergency personnel on the nature of a disaster.

An alert management system according to the invention has been previously described in autonomous and connected modes for which the alert can be considered as descending, that is to say triggered by the person in distress by 1 actuation of an alarm triggering object 20 emitting an alert triggering message Ma interpreted a device for emitting a lightning alert 10, cooperating with said triggering alarm object 20, propagating said alert lightly, or even radio, to destination of the outside world including a rescue center 40-1. An alert management system according to the invention can also manage an alert in an ascending way, that is to say an alert triggered by a third party, witness of a disaster or a loved one, possibly located at hundreds of kilometers from the theater of such a disaster, or even a rescue center that would have been informed by any channel of the need for urgent intervention. In connection with FIGS. 4 and 5, the purpose of this variant is to first adapt the alert management server 30, so that its processing unit 31 can interpret an alarm trigger message. by MaT delegation when it has been received by the communication means 34 of said server 30 and sent by a call server 60 or by any electronic entity designed for this purpose in response to an alarm trigger call Aa. Such an adaptation of said server 30, for example by purposely designing the application program P2 installed in the program memory 33 of said server 30, allows the processing unit 31 of the latter to deduce from said message MaT the value of a data characterizing a device for transmitting a light alert 10, 10A, 10B according to the invention and as described above, for example the value of an identifier 110. The processing unit 31 of said management server of an alert 30 can then implement a step of searching in the data memory 32 and reading a data structure PP1 or PPn associated with said value of a data characterizing a device for issuing a light alert. By way of example, such a data structure PP1 or PPn could comprise a field recording the value of the identifier 110 of the device 10, 10A, or 10B. Such a reading step, implemented by the processing unit 31 of the server 30, enables the latter to produce an emergency call message Ma intended for said device to emit a light alert thus identified, and to trigger the transmission of said emergency call message Ma by the communication means 34 of said management server an alert 30. Thus, the latter turns into an alert trigger object. Without requiring any adaptation, the device 10, 10A or 10B recipient of said message Ma, implements, through its processing unit 12, a method of interpretation of said message Ma and triggers the light alert and / or developing and issuing an Ms distress message as mentioned above. Other modifications may be envisaged without departing from the scope of the present invention defined by the appended claims.
