Description

Title of the invention: Individual safety detection and protection device and its implementation method

[0001] The invention relates to the field of individual safety detection and protection devices.

[0002] The invention will be more particularly described with regard to a device for detection and individual safety protection for warning a user of a danger, a risk, which would be detected in an area where the user is located.

[0003] In a well-known application which is that of people working in a shared environment such as a warehouse where mobile machinery circulates, safety devices are known which are worn by the personnel, which make it possible to warn of danger when a mobile machinery approaches the individual wearing a device. A safety device comprises a receiver which detects the signals transmitted by a transmitter fixed on the mobile machinery and which in response, delivers an alarm signal to the individual to be protected. This alarm signal can be an audible signal, a visual signal or even in the form of a vibration capable of being felt through clothing.

[0004] However, these safety devices are designed to communicate only with mobile vehicles that have been pre-equipped with transmitters and are therefore identified in advance as intended to move in the area where the person to be protected will be. These devices cannot therefore be applied to all situations, in particular for unknown vehicles that are only passing through the environment of a person to be protected. For example, road workers working on a road or firefighters responding to a road accident may not perceive the danger of vehicles approaching them.

[0005] In another situation, for example, it would be a wildlife photographer who, in a fixed waiting position, would not see the danger of an animal such as a bear coming from behind him. In yet another situation, it would be a soldier focused on his objective, who, having to remain motionless, would not be able to systematically detect a threat coming from behind him.

[0006] Therefore, in many situations, there is a need to secure a person temporarily in an area in which they are immobilized or in which they are moving, while a danger may arise even before they are aware of it and react.

[0007] The invention therefore aims to propose a device for detection and individual safety protection to warn a person in a delimited area of ​​a danger or risk which is likely to occur without them being able to avoid it. notice or too late.

[0008] According to the invention, the individual safety detection and protection device, in particular for warning an individual of a danger (likely to approach this individual), comprises, on the one hand, a portable individual equipment equipped with at least one remote reception and transmission system (intended to communicate with at least one remote signal transmitter and preferably with other portable individual equipment and other external remote communication devices), and on the other hand, a system for delivering at least one alarm signal (in response to the reception of a signal by the reception system, the signal being considered as an alert signal), the individual safety detection and protection device being characterized in that it comprises at least one detection module,preferably several detection modules capable of communicating with said at least one remote reception and transmission system of the individual equipment, and in that the detection module(s) are stored in the individual equipment when not in use and are removable relative to said equipment (in order to be deployed at a distance from the individual), the or each of the detection modules being provided, on the one hand, with removable fixing means relative to the equipment, and on the other hand, with temporary fixing means intended for fixing them in the use position on a reception surface remote from the individual.

[0009] Subsequently, the individual safety detection and protection device is called a “safety device”. The data reception and transmission system will sometimes subsequently be called a “reception system”.

[0010] The term "temporary protection zone" means an area in which the individual temporarily confines himself and implements the individual security detection and protection device for the time he remains in this area.

[0011] In the remainder of the description, the term “detection module” means a module comprising either a single signal transmitter, or a signal transmitter and a signal receiver, or a signal transmitter, preferably with a receiver, and coupled to a detector, and possibly at least one actuator.

[0012] According to one characteristic, the individual equipment comprises electronic means for processing data.

[0013] Consequently, the detection module(s) become nomadic by being able to be installed in the danger zone, regardless of where it is located and being able to be stored again in the portable equipment after use. Thus, regardless of where the individual to be protected is, the latter, carrying the equipment with a reception system which is capable of communicating remotely with the detection modules, will be systematically secured. Indeed, the user will detach the detection modules he needs from the equipment and position them in the protection zone. that it will have delimited, the detection modules communicating remotely with the reception system to inform of a danger. The detection modules will be placed on fixed objects which are located at the edge of the protection zone and in front of which the danger can pass, and / or on mobile objects constituting a potential danger when these objects move in the protection zone.

[0014] Thus, the security device of the invention provides an all-in-one device, integrating the detection modules and the reception system, being easily transportable due to individual equipment worn by the individual, and being easily and quickly implemented on site in the area to be monitored, due to the fact that the detection modules are removable and provided with temporary fixing means to fix them to any surface in the area to be monitored. The implementation of the security device is immediate, without adjustment and preferably silent when the alarm signal is haptic.

[0015] According to one characteristic, the remote reception and transmission system of the equipment is capable of communicating with other individual equipment (similar to the invention) and / or with detection modules of at least one other security device of the same design as said aforementioned individual security detection and protection device of the invention and / or with external networks to transmit data from the equipment and / or detection modules, and to receive data.

[0016] According to one characteristic, the detection modules communicate with each other and possibly with the detection modules of at least one other device of the same design. The detection modules communicate with each other to create a detection network and / or to serve as data transmission relays.

[0017] According to one characteristic, the detection modules and the remote reception and transmission system communicate by optical and / or acoustic transmission (in particular in a marine environment) and / or sound and / or ultrasonic and / or radio.

[0018] In a particular embodiment, the detection modules and the reception system transmit by radio frequency, i.e. high frequency (HF). HF guarantees 100% reliable reception (without loss of communication) regardless of obstacles, including hard obstacles such as walls, which makes it possible to transmit underground, in a building, or through a building. Advantageously, the detection modules are designed to transmit up to approximately 800 m. The frequency or frequency range will be selected in particular depending on the location and the application.

[0019] Advantageously, the detection modules are intended to be installed at appropriate locations to delimit the temporary protection zone. Preferably, the equipment comprises at least three detection modules.

[0020] According to one embodiment, a detection module comprises only one transmitter which can transmit continuously; this scenario applies for example to the use of a previously identified vehicle which will be equipped on site at the last moment when it is known that it must move in the area where the individual is located.

[0021] According to one feature, a detection module comprises either a single signal transmitter, or a signal transmitter and a signal receiver, or a signal transmitter, preferably with a receiver, and coupled to a detector and possibly at least one actuator. According to a preferred embodiment, a detection module comprises a transmitter and a receiver (the receiver making it possible to receive signals from the equipment and possibly to communicate with other detection modules and other individual safety devices of the same design), and at least one detector (and its sensor), and possibly at least one actuator.

[0022] The desired sensors will be integrated into a detection module depending on the detection sought, for example a detection module will be able to identify a face, an object, a vehicle, an animal, and / or will be able to listen such as in the sound, ultrasound, infrasound domain and in the electromagnetic spectrum, and / or will be able to follow a trajectory of a land vehicle, a drone, a marine and underwater vehicle, people, animals.

[0023] For example, a detector of a detection module comprises a sensor chosen from: imagers, infrared sensors, laser detection sensors, also called LIDAR (acronym for the English expression “Light Detection And Ranging” or “laser detection and ranging”), radar sensors, electrochemical sensors, electrolytic sensors, vibration sensors, seismic sensors, seismological sensors, temperature sensors, sound sensors (microphones), piezoelectric sensors, etc.

[0024] In a particular example, said at least one detector of a detection module is a presence detector, preferably the presence detector operating according to radar technology. Radar technology is reliable regardless of climatic conditions and allows the detection of people or animals. In addition, there is no need to illuminate the area to be monitored, which allows for discretion.

[0025] Advantageously, the detector of the detection module integrates the signal processing function (it is an intelligent detector), which makes it possible to save energy.

[0026] Depending on the intended application, the detection module may include, in addition to detection, one or more actuators, which, depending on the detected signal, generate the production of an action. For example, in the event of detection, a diversion function such as light diversion (for example an explosion of magnesium to produce a bright light and dazzle momentarily), sound diversion, pressure variation diversion, or diversion in the form of a smoke screen.

[0027] According to one characteristic, each detection module and the equipment with respect to its technical components each comprise a waterproof body and the manufacturing material of which is resistant to hot and cold climatic conditions, in particular the material is in a plastic material resistant to hot and cold climatic conditions such as polyamide.

[0028] According to one characteristic, the system for delivering at least one alarm signal is designed to deliver a light and / or sound and / or haptic signal, in particular vibratory and / or electrical and / or by application of pressure and / or by friction. A vibratory signal is in particular correctly felt by the human body (in particular through clothing). This type of signal is reliable with respect to its reception and rapid, the individual feeling it systematically and immediately. In addition, this signal remains discreet. It is not noisy unlike an audible signal, which is advantageous in certain situations where silence is essential.With a vibrating signal, there is no need for a display screen unlike an on-screen alert signal which also poses several disadvantages such as the need for the user to always have an eye on his screen or as in certain circumstances for which the lighting of the screen can be a disadvantage (this can be seen at night when one wants to remain discreet) or the quality of the lighting is insufficient (in broad daylight, the sun can prevent one from seeing the screen properly). Alternatively, any other haptic technology can be considered, such as via an electric current and / or the application of pressure or tightening, and / or by friction. Of course, depending on the intended use, if it does not require, for example, audible or visual discretion, the alert signal can be audible and / or visual.

[0029] According to one feature, the system for delivering at least one alarm signal is integrated into the individual equipment or is separate therefrom. The system for delivering at least one alarm signal may be separated from the individual equipment to be placed at a location on the user that maximizes the effectiveness of communication or that does not interfere with other equipment worn by the user, depending on the nature of the alarm signal(s). It may be in the form of or be integrated into one of the following elements, alone or in combination: fabric, case, patch, mobile phone, electronic tablet, eyeglasses, optical binoculars, observation glasses, protective mask glasses, virtual reality headset, augmented reality glasses, hearing aid earpiece, noise-cancelling headphones, audio headphones.

[0030] Advantageously, the system for delivering an alarm signal is capable of delivering the alarm signal according to an amplitude and / or a frequency (repetition of the signal) variables to correspond to a given degree of danger, in particular according to an amplitude and / or a frequency intensifying according to the approach of the danger or the level of the danger.

[0031] According to one feature, the system for delivering at least one alarm signal comprises one or more alarm signal delivery components which are integrated and / or external to the individual equipment (being external, the components are able to communicate with the equipment), several components being able to deliver separate alarm signals or being able in combination to deliver a single signal according to a specific signal pattern or model, in particular depending on the nature of the danger. The term "signal pattern or model" means a signal from a category of signals, for example the category of vibration signals, and having its own vibration characteristics relative to each of the components.For example, it is possible to vibrate components in a given order or at the same time, and depending on their location, this makes it possible to create a vibration pattern that corresponds to a type of danger (the user will feel on his skin in vibrational form like a pattern being drawn, each pattern being different depending on the danger).

[0032] According to one characteristic, the safety device comprises batteries arranged in each of the detection modules and in the individual equipment; at least the battery of the individual equipment, preferably all of the batteries, is rechargeable either by induction or by electrical conduction.

[0033] According to one characteristic, the stopping and starting of the detection modules is managed at the level of the individual equipment and / or the detection modules.

[0034] Advantageously, the equipment is a garment or part of a garment, in particular a cuff, or an accessory attached (preferably removably) to the garment, or an accessory intended to be affixed directly to the user's body such as a patch stuck to the skin. Thus, the equipment is directly worn by the individual to deliver an alarm signal as close as possible to the individual. The equipment is therefore not placed in a bag or package, at the risk of being inaccessible and the individual not being able to perceive the alarm signal. For example, in the form of a cuff by being positioned on a forearm, the equipment and therefore the safety device is light and makes the transmitters / detection modules easily accessible for detaching them.

[0035] The means for removable attachment of the individual equipment to the individual user are, for example, a self-gripping fastening and closing system of the Velcro® type. The means for removable attachment of the individual equipment are designed to make the equipment ergonomic, light, comfortable, and adapted to the area of ​​the human body where the equipment is placed.

[0036] According to one characteristic, the removable fixing means of the detection modules in relation to the equipment are magnetically fixed and / or by removable gluing and / or by mechanical connection such as by clipping and / or by connection implement the Van der Waals forces.

[0037] The detection modules are held on the outside of the equipment, preferably in suitable shaped reception housings, by removable fixing means such as magnetic fixing, or mechanical fixing, in particular by clipping, or by depression, or by a sticky surface, or by a textured surface implementing Van der Waals forces. The removable fixing means are capable of ensuring that the detection modules are held on the equipment regardless of the user's activity, by resisting external forces such as shocks, vibrations, accelerations, depressions, friction, and this regardless of the altitude, in the air, on land, underwater or in space.

[0038] According to one characteristic, the temporary fixing means intended for external fixing (on a receiving surface) of the detection modules are magnetically fixed and / or by removable gluing and / or by mechanical connection such as by clipping and / or by connection using Van de Waals forces.

[0039] In particular, a detection module has a closed body inside which a magnet is arranged in order to fix the detection module magnetically when the receiving surface allows it, and / or outside which a removable capsule is arranged containing an adhesive and / or the external surface of which has a textured gripping surface implementing Van de Waals forces. For example, the capsule contains an adhesive in the form of a gel which is protected by a cover, the cover being intended to be removed in order to stick the detection module to any receiving surface. When the detection module is recovered, it is detached from the capsule, and a new adhesive capsule is inserted for the next use. The capsule is fixed to the rear of the detection module for example by clipping.

[0040] The security device may advantageously comprise location systems which are integrated into the equipment and / or into the detection modules, and may be capable of managing the failure of its operation by checking in particular the level of the power supply batteries of the detection modules and of the equipment as well as the quality of transmission of the signals. The identification and transmission of the location make it possible, during use, to know the location of the individual and respectively of the transmitters of the detection modules which have been detached and placed at a distance from the equipment. The location preferably operates by GNSS (for "global navigation satellite Systems" in English, i.e. location by satellite).

[0041] The safety device may have other characteristics, in particular: - it is capable (via electronic processing means) of communicating with external networks (in particular by mobile telephone waves to transmit over a long distance or by Bluetooth to transmit to a smartphone carried by the user), which makes it possible to transmit simultaneously with the alarm signal perceived by the individual another remote alarm signal, or to transmit information relating to said security device or to similar security devices of the invention or even by serving only as a relay; - it is capable (via electronic processing means) of communicating information in an order of priority, for example it will first communicate an “intrusion into the perimeter of the zone” alarm signal, then an “imminent danger” alarm signal.

[0042] Thus according to one characteristic, the security device, in particular the equipment, comprises electronic processing means which comprise an electronic card arranged in the equipment, in particular inside a closed housing, the electronic card being designed to communicate with external networks by Bluetooth and / or wifi and / or mobile telephony communication, and / or to communicate with other similar security devices and / or to manage failures in its operation such as by checking the battery level and the quality of signal transmission,

[0043] According to the invention, the safety device is used in the military and civil security fields, such as for police officers or firefighters, for the safety of road workers, explorers, field reporters, etc.

[0044] The invention also relates to a method for implementing the aforementioned individual security detection and protection device of the invention to protect an individual user, the method comprising the following steps: - the user equips himself with the individual equipment and a system for delivering at least one alarm signal, preferably said system for delivering at least one alarm signal being integrated into the equipment; - when the user is in a temporary area to be protected, he activates the individual equipment (via an ON button for example), the detection modules remaining inactive; - the user detaches from the equipment the detection module (if there is only one) or a first detection module (if there are several), which activates the detection module and allows the exchange of information between the equipment and the detection module (for example the transmission of information from the equipment to the module, which is at least relative to the allocation of an identification number to said module); - the user then fixes this first detection module on a reception surface via the temporary fixing means; - in the case of a plurality of detection modules, the user detaches the equipment and attaches each of the other detection modules to deploy them in the area at strategic detection locations; - the user can then remain in the temporary area to carry out a (his) task; - once the task is completed, the user wishing to leave the temporary area, goes to each of the detection module locations, detaches them from the reception surfaces and reinstalls them on the equipment using the removable fixing means.

[0045] The detection modules operate in particular until they no longer have a battery; they can advantageously recharge when they are reinstalled on the equipment.

[0046] The present invention is now described using examples which are solely illustrative and in no way limitative of the scope of the invention, and from the attached illustrations, in which: - [Fig.l] represents a schematic sectional view of an exemplary embodiment of a detection and individual safety protection device according to the invention, the individual equipment of which is in the form of a cuff to be fixed to the forearm of a user and the detection modules being in their stored position and fixed to the equipment. - [Fig.2] is a perspective view of the safety device of [Fig.l], the individual equipment being held on a forearm of a user and the detection modules being detached. - [Fig.3] represents a schematic and detailed sectional view of a single detection module, detached from the equipment. - [Fig.4] illustrates a schematic view of a user wearing the safety device equipment as in [Fig.2], the user being in a temporary protection zone, covered by the detection modules which have been positioned in the appropriate locations. - [Fig.5] illustrates a schematic view showing the transmission of a security device of the invention via its equipment with at least one other security device of the invention.

[0047] Figures are not to scale for better understanding.

[0048] The individual security detection and protection device 1 of the invention illustrated in Figures 1 and 2 is a nomadic security device intended to detect an element approaching an individual or an element occurring in a so-called temporary protection zone Z around the individual ([Fig.4]) and to inform the individual thereof.

[0049] The safety device 1 is notably used to warn of danger to an individual who is temporarily in a fixed location or moving within a protection zone to be delimited.

[0050] For example, the safety device 1 as a danger safety device is used to detect the approach of a large wild animal, a person, a group of people, a vehicle, a vehicle with excessive speed, a toxic gas, an explosive gas, radiation, excessive temperature, fire, etc.

[0051] The security device 1 has the advantage of being portable by the user and nomadic with simple and rapid implementation in any location that the individual has decided to temporarily occupy.

[0052] With reference to Figures 1 to 3, the security device 1 comprises an individually portable equipment 10, one or more detection modules 2, which are removably attached to the equipment 10, a reception and transmission system 3 which is integrated into the equipment 10 and is capable of communicating remotely with the reception modules 2, of receiving their signal and preferably of transmitting data to other remote devices which may in particular be other security devices IA of the invention ([Fig.5]), and a system for delivering at least one alarm signal 4 capable of immediately warning the user in the event of reception of a signal considered to be at risk by the reception and transmission system 3.

[0053] Each of the detection modules 2 comprises a transmitter 20, and depending on the use made of the safety device 1, each of the transmitters 20 may or may not be coupled to a detector 5 or to several detectors which have a different detection function. Each transmitter 20 or each transmitter 20 / detector 5 pair is housed in the detection module 2 which is removable relative to the equipment 10 and which is capable of being fixed to any receiving surface. Preferably, the detection module 2 comprises, with the transmitter 20, a receiver 20'. The transmission and reception function for each detection module 2 makes it possible to exchange information with the equipment 10, in particular so that the equipment 10 can at least assign an identification number to each of the detection modules 2 when the equipment is put into operation and the detection module 2 is detached from the equipment.

[0054] Thus, the equipment 10 is an all-in-one and allows the individual in any location to have the detection modules 2 on him, to deploy them in the temporary area where he will be, to be warned immediately in the event of detection, and to take back and store the modules for later use. The particularity of the security device 1 is to have portable and nomadic individual equipment (systematically transportable with the individual anywhere), which integrates the detection modules 2 so as not to lose them when not in use, to have them conveniently available as soon as necessary, and whose removability allows them to be temporarily installed in the ad hoc locations of the area to be protected while adapting to the area, as well as to be able to re-store them for later reuse.

[0055] According to a first embodiment, the individual to be protected moves in a temporary zone where a mobile device is moving which does not have any system for sending an approach signal. The individual, carrying his equipment 10, can then detach a detection module 2 and place it temporarily on the mobile device. As soon as the mobile device and therefore the detection module 2 approaches too close to the individual carrying the receiver 3, an alarm signal will be triggered. In this case, there is no need for a detector coupled to the transmitter.

[0056] According to a second embodiment which is that illustrated in the figures, the individual to be protected is static or mobile in a temporary protection zone Z which is intended to be monitored by detectors to warn the individual in the event of detection. Here, each detection module 2 comprises a transmitter 20, a receiver 20' and a detector 5.

[0057] More particularly, the example described relates to the detection of people or animals that cross the limits of the protection zone and move towards the person to be protected. The detectors 5 are presence detectors. The invention is not limited to providing the equipment 10 with presence detectors, and applies to other types of detection such as the detection of gas, radiation, temperature, etc.

[0058] Furthermore, a detection module 2 may comprise, in addition to detection, one or more actuators 6, which, depending on the detected signal, generate the production of an action. For example, in the event of detection of a presence by the detector 5, a diversion function will be produced such as sound diversion by a siren triggered by an actuator 6 integrated into the detection module 2.

[0059] The equipment 10 is, by way of non-limiting example, a cuff attached to a forearm ([Fig. 3]). The equipment 10 comprises removable attachment means 11 ([Fig. 1]) for said equipment on the user. The removable attachment means 11 are, for example, attachment and closing systems such as self-gripping strips of the Velcro® type. Other removable attachment means 11 for the equipment may be envisaged.

[0060] The equipment 10 comprises a closed casing 12 in which the reception and transmission system 3 and electronic data processing means 7 are housed, which are necessary for the operation of receiving and managing the signals from the detection modules 2, for triggering an alarm signal by the delivery system 4 in the event of detection of a risk and preferably for the management and transmission of data to the outside outside the detection modules.

[0061] The envelope 12, at least on its face intended to be in contact with the user, is partly made of a fabric to be ergonomic and allow good support on the user. The fabric is preferably a technical fabric to promote ventilation. natural between the user's body part and the equipment 10 for the user's comfort. The equipment 10, in particular the casing 12 which houses the functional technical components, is made of a material resistant to hot and cold climatic conditions; the material is for example polyamide. The equipment 10 is furthermore waterproof.

[0062] The envelope 12 houses inside it in particular the reception and transmission system 3 which can include the additional function of transmission and reception towards other devices than the detection modules 2, the electronic data processing means 7, here the delivery system 4 of at least one alarm signal, and at least one rechargeable battery 8.

[0063] Outside the casing 12, the equipment 10 comprises reception housings 9 for storing the detection modules 2 when not in use, the detection modules 2 preferably being directly accessible. By "directly accessible" is meant the fact that they are visible and directly grippable. Each of the reception housings 9 comprises removable fixing means 90 for the detection modules 2 in order to detach them for use and then reattach them after use. The removable fixing means 90 are arranged externally and / or internally to the casing 12. As a preferred example, the fixing of the detection modules 2 with the reception housing 9 is magnetic; for this purpose, each detection module 2 comprises a magnet 21 while a magnetic part 90 is arranged inside the casing 12 and opposite the bottom of the housing 9.The magnet 21 is preferably integrated into the detection module 2 to also serve as a magnetic fixing means during its use (detached from the equipment) if the receiving surface is ferromagnetic. Alternatively or in a complementary manner, the detection module 2 and the receiving housing 9 may comprise means of mutual cooperation by clipping. Other fixing means may be envisaged.

[0064] Outside the casing 12, there is also provided a control member 13 for operating the equipment, which may be in the form, for example, of a single ON / OFF button.

[0065] The electronic data processing means 7 comprise a microprocessor and manage the data transmitted by the detection modules 2 in order, in response to a detected danger signal, to control the system 4 for delivering an alarm signal. The electronic processing means 7 may comprise a communication protocol which makes it possible to describe the danger and to adapt the amplitude and / or the frequency of the alarm signal delivered by the delivery system 4. For example, the information received by the electronic processing means 7 is different if a vehicle arrives at low speed or at high speed or if the danger is more or less close to the user; the alarm signal will then be adapted.

[0066] The system 4 for delivering an alarm signal is housed inside the casing 12 and is capable of delivering the alarm signal externally to the casing 12 and therefore externally to the equipment 10. The system 4 for delivering an alarm signal is capable of delivering, for example, at least one vibratory signal which is intended to be felt by the user. For this purpose, the system 4 for delivering an alarm signal comprises, for example, a piezoelectric element.

[0067] [Fig. 3] illustrates in more detail a detection module 2. The detection module 2 comprises a closed body which houses the transmitter 20 and the receiver 20' and the on-board electronics for data processing and data exchange with the outside, the detector 5, possibly an actuator 6, a battery 22 such as a cell, and the magnet 21 for magnetically fixing the detection module. The detection module 2 is preferably openable to change the battery 21. Alternatively, the battery may be a battery rechargeable by induction or electrical conduction.

[0068] The transmitter / receiver assembly 20, 20' operates for example by radio waves.

[0069] In addition, the detection module 2 comprises temporary fixing means 23 which are external to the body of the module and serve to fix the detection module to any receiving surface of any nature whatsoever. The temporary fixing means 23 of the detection modules 2 are designed to fix the detection modules quickly and uninstall them just as quickly. As a preferred example, the temporary fixing means 23 are a glue capsule removably fixed to the rear of the body of the detection module, for example by clipping. The capsule 23 is protected by a cover which is removed in order to stick the detection module 2 to any receiving surface. When the detection module 2 is recovered, it is detached from the capsule 23, and a new glue capsule is inserted for the next use.

[0070] The detector 5 is here a presence detector 2, for example an imager which also makes it possible to identify. Preferably, the presence detector detects at an opening angle of 80°.

[0071] The detection module 2 has a body whose material is resistant to hot and cold climatic conditions; it is for example made of polyamide. The detection module 2 is also waterproof.

[0072] The detection module 2 is preferably designed (by its on-board electronics) to manage its various failures and to warn the equipment 10 whose electronic processing means 7 will pass the information on to the user so as not to put him in danger. The failures are in particular the low autonomy of the battery 22, the degradation of the transmission. The information to the user is carried out by the delivery system 4 of an alarm signal, the alarm signal of battery failure of the detection module will advantageously be different from the signal of a risk or a danger.

[0073] The method of implementing the safety device 1 is now described with reference to [Fig.4].

[0074] The user carries the equipment 10 with the detection modules 2 stored and maintained in their reception housing 9. When the user arrives on site, he turns on the equipment 10 (ON button), he detaches a first detection module 2, which will trigger its activation and its pairing with the equipment by automatically assigning it an identification number. Then the user fixes the detection module 2 on a reception surface in a strategic location. He repeats the same operations for the other detection modules 2 (he removes and fixes) by deploying them at strategic locations ([Fig.4]) to cover the temporary protection zone Z. The fixing of each of the detection modules 2 is done via the temporary fixing means 23, such as by gluing, and / or magnetically via the magnet 21 if the reception surface allows it.

[0075] If a presence arrives in the detection field of a detection module 2, the detection signal is automatically sent to the equipment 10 which instantly alerts the user by sending an alarm signal, for example a vibratory one, via the delivery system 4 through the equipment 10 and at the user's body. Alerted, the user can act accordingly. If the detector 5 of the detection module 2 is an imager, the captured image will preferably be transmitted to the equipment 10 which will transfer it, for example, to the user's smartphone and / or to an ad hoc complementary monitoring device remote from the individual.

[0076] When the user is ready to leave the protection zone Z, he will detach each of the detection modules 2 and immediately replace it in the reception housings 9 of the equipment 10 very easily and quickly because it is directly accessible and quickly removable.

[0077] Finally, with regard to [Fig. 5], a first safety device 1 can communicate remotely via its individual equipment 10 with a second individual safety detection and protection device such as IA, similar to the safety device 1 and via its own individual equipment 10A, or even communicate remotely with several other safety devices of the invention.
