    .3
    The present invention relates to the general field of simulators for handling a fire extinguisher device by a user.
    BACKGROUND OF THE INVENTION
    More specifically, the invention relates to a simulator for handling a fire extinguishing device by a user, the simulator comprising at least a first dummy fire extinguishing device with a dummy lance and at least one actuator · manually operable by the user between an active state and an inactive state.
    Such a simulator is described by the patent document WO20O7117795. This: document presents a dummy fire extinguisher device: (in this case a fac15 tice extinguisher) presenting a dummy lance carrying an emitter of a light ray intended to generate a light impact on a screen installed: facing the user. Sensors detect this impact on the screen and as a function of this detection vary a display of flame on the screen.
    This simulator is unrealistic since the user must aim, with the lance of the artificial fire extinguisher device, at a screen which is placed on the ground in front of him. It is therefore desirable to improve the realism of the simulation.
    OBJECT OF THE INVENTION
    An object of the present invention is to provide a simulator for handling a fire extinguisher device by a user having improved realism.
    SUMMARY OF THE INVENTION
    To this end, there is proposed according to the invention a simulator for handling a fire extinguishing device by a user, this simulator comprising at least one first dummy fire extinguishing device provided with a dummy lance and at least one actuator manually actuated by the user between an active state and an inactive state.
    This simulator according to the invention is essentially characterized in that it also includes:
    a display device arranged to be worn by the user to display Images before the eyes of this user,
    a device for estimating the orientation of said dummy lance in said real environment where the first dummy extinction device is also located;
    - a computer;
    the computer being functionally connected:
    - audit at least one actuator of the first dummy fire extinguishing device to know a current state in which this at least one actuator is among its active · and inactive states /
    - The orientation estimation device for estimating a current orientation of said dummy lance in its real environment; and the display device for displaying, for the attention of the user, an image of a virtual environment in which are represented · at least one virtual fire and at least one virtual fire extinguisher lance oriented in 1 virtual environment as a function of the estimated current orientation of the dummy lance in the real environment.
    Thus, thanks to the display device that he wears, the user is immersed in a virtual environment where at least one virtual fire is displayed and at least one virtual lance, the orientation of this virtual lance.
    3:
    in this virtual environment being done by directing a dummy lance which is a real physical object being in the real environneirieht.
    Since the first dummy device has at least one actuator which can be actuated manually by the user, the user has a real impression of actuation of the actuator of the dummy device and this actuation is detected by the computer to generate effects in the virtual environment. The effect of immersion and realism 10 perceived by the user is thus improved since he perceives on the one hand tactile information: and proprioceptlorï generated by his real interaction with: the first dummy device that he actually manipulates and on the other hand information displayed in the νινί 5 fuel environment, via the display device which he wears and which moves: therefore with the user. This impression of immersion is all the stronger since there is a correlation between an orientation · estimated in the real environment of the lance of the first dummy device and an orien20 ta tien, of the virtual lance: displayed in the virtual environment and that the display device is such that it completely masks the view, by the user, of the real environment.
    Thus, the impression of the user is improved realism perceived by the system according to the invention.

    DETAILED DESCRIPTION OF THE INVENTION 10 As indicated above, the invention relates to a simulator 1 for the manipulation of at least one fire extinguishing device D1, D2, 03, 04, 05 by a user U.
    As illustrated in FIG. 1, the simulator 1 Côm15 takes at least a first dummy fire extinguisher device Dl provided with a dummy lance El and at least one actuator Al which can be actuated manually by the user between an active state and an inactive state.
    The simulator also includes other: dummy extinction devices: fire 02, 03, D4, 05 similar to the first device Dl.
    Each of these others: artificial fire extinction devices D2 to D5 includes:
    - at least: its own dummy lance E4, L5 (here only 25 the lances Ll, L4, L5 of the devices Dl, 04, 05 are represented :); and
    - at least its own actuator A2, A3, A4, AS: manually actuable by the user 0 between an active state and an inactive state.
    Each of the artificial fire extinguishing devices Dl, 02, D3), D4, 05 carries a means of its identification by a computer 4 (for example a visible code
    G on optical markers worn by each of dummy devices can be used to identify each of these devices D1-D5).
    The simulator 1 also comprises a display device 2 arranged to be worn by the user 0 to display images · before the eyes of this user while covering his entire field of vision to mask the real environment surrounding the user. In this case, this display device 2 is a headset visio10 in connection with one or more virtual reality software programs executed by the computer 4 to display an image of a virtual environment in front of the eyes of the user. The display device 2 is such that when it is worn by the user U, the latter cannot observe the real environment in which he is located but he can only observe the image displayed by the display device 2 .
    The simulator 1 also includes a device for estimating the orientation of said dummy ·· lance L1 of the device Pl in said real environment 3 where this first dummy extinction device Dl is located.
    The estimation of the orientation of the lance · act ice L1 in the real environment can be done for example by estimation of the orientation of the dummy lance · with respect to a real reference whose origin is in 1 ' real environment.
    The computer 4 is functionally connected to this orientation estimation device 5 in order to minus estimate a current orientation of said dummy lance 'L1 in its real environment 3.
    The orientation estimation device 5 and the calculator are also arranged to estimate the current positions and current orientations of each of the dummy lances L1, L4, L5 of the various dummy devices Dl, D2, D3, 04 T D5 in 1 ' real environment 3.
    As can be seen in FIG. 1, some at least 5 of the artificial fire extinguisher devices ·, in this case, the devices Dl to 04 each have a body above which the imaginary lance L1 is connected, L4.
    Each body C1, C2, C3, G4 has a volume of several 'liters · and a mass of several kilos for simu10 1er, as realistically as possible, a reserve full of real extinguishing agent of a similar volume. It is sought here so that the user entering any of the devices D1 to D5 has an impression of proprioception. identical to the one he would have if he wore a real fire extinguisher and the same size and dimensions as · the dummy device. For this, the body of a dummy device can be ballasted.
    The orientation estimation device 5 and the computer 4 are also preferably arranged for · esti20 mer, for each body · given Cl to C4 of dummy device Dl to D4 present and identified in the real environment 3, a current orientation and a current position specific to this given body - in the real environment 3.
    The orientation estimation device 5 of each lance L1 to L5 comprises · lance markers, in this case, each lance carries at least one optical marker which corresponds to it.
    The device for estimating the orientation S of the dummy lances also comprises optical sensors · functionally connected to the computer 4 to allow the computer 4 to deduce the position and the orientation of each of the lances il, L4, L5 in the real environment.
    The simulator 1 also includes a device 9 for detecting the position of hand (s) 8 of the user U in
    The real environment 3 functionally connected to said computer 4.
    This position detection device 9 of hand (s) 8 comprises hand markers respectively arranged to be worn on the hands of the user 0. These hand markers can for example ·, as illustrated in FIG. 1, be attached to gloves worn by the user.
    Optical sensors 9a arranged in the real environment 3 can be functionally connected to the computer 4 to deduce (by observation of the markers located in the real environment) the current / respective positions and orientations of the objects which carry optical markers like c 'is the case: of the hand (s) 8, of the lance (s) Ll, L4, US, of the body (s) Cl to C4 and possibly of the display device 2.
    The optical sensors 9a are, for example, sensors from infrared cameras placed in the real environment 3, around the user and devices - DI to D5 for locating the positions of the markers in the real environment and deducing the positions therefrom. and orientations of objects (hands, spears, bodies) so marked.
    These optical markers (symbolized in FIG. 1 by dots) can be produced with reflective markers of radiation and / or by emitting leds: such as infrared leds: fixed on the objects: to be located.
    The at least one of the optical sensors 10 can be:
    3: 0 arranged to capture only the position and orientation of the display device 2. This makes it possible to use means: of location 10 specifically dedicated to display devices and other means of location specifically dedicated atx other objects to locate.
    The observation of the markers with optical sensors 9a, 10 allows the calculat eut 4 which is functionally connected to these optical sensors Sa, 10 to estimate / locate the respective positions and orientations of each marked object present in the real environment 3 .
    We use here;
    - the reflections emitted by the markers carried by the devices D1 to D5 and by the hands 8 to identify the: respective positions / orientations of these objects via the optical sensors 9 to infrared cameras; and
    - the infrared radiation emitted by the LEDs fixed on the head-mounted display 2 in order to deduce therefrom the position and the orientation of the head of the user 0 in the real environment 3- via the sensor of the camera 10.
    The computer 4 is also functionally connected to the display device 2, in this case to the head-mounted display in connection with · the · virtual reality software, to display, for the user, an image of a virtual environment IM in which are represented at least one virtual fire 6 and at least one virtual lance Lvl for extinguishing a fire oriented in the virtual environment as a function of the estimated current orientation of the corresponding dummy lance L1 in the real environment.
    As shown in Figures 2 to 5, this computer 4 is also designed to:
    varying an Orientation of Observation of the virtual environment as a function of the current orientation of the display device 2 in the real environment 3; and / or for
    - order the display in the IM image of at least ίο a virtual hand; 8v whose position in the virtual environment is a function of the detected hand position 8 of the user U in the real environment 3.
    The realism of the immersion is improved because the calculator 4 is functionally connected to the orientation detection device 10 of the display device, to receive information representative of the movements of the head; in the real environment and deduce an observation position and an observation orientation from
    The corresponding virtual environment
    Depending on the estimated position and observation orientation in the real environment Via the orientation detection device 10 of the display device 2, the calculator 4 transmits data representative of an image IM of 1 virtual environment to be displayed, this IM image being observed according to virtual observation position and orientation similar to those estimated; in the real environment.
    User U can change the position and orientation of observation in the virtual environment by simply moving his head and therefore the display device in the real environment.
    To refine the quality of the position and orientation detection of the display device in the real environment 3, we; can also ensure that · the orientation detection device 10 comprises a coupled gyroscope; to an accelerometer mechanically attached to the display device 2. There is thus a detection of movements; display device on six axes, three axes of rotation and three axes of positioning.
    Preferably, the computer 4 is also arranged to position said virtual hand · 8v relative to; the virtual lance Lvl corresponding to the device, dummy used Dl according to the current position of the dummy lance L1 used · in the real environment 3 and the detected position · laughs the hand 8 of user 0 in the real environment 3 : .
    The computer 4 is also arranged to command the display device 2 to display in the virtual environment image IM, virtual bodies each representative of one of the bodies C1, C2, C3, C4 of the corresponding dummy devices. Each virtual body is in a position and a current orientation which is specific to it and which is defined as a function of the estimated orientation and of the estimated position of the dummy device body which corresponds to it in the real environment 3.
    Thus, the user U has, in the virtual environment in which he is immersed ·, a representation of the dummy devices Dl to D5 which surrounds him with a virtual representation of the dummies and dummy bodies in the virtual positions and orientations which correspond substantially to the real positions and orientations of these spears and bodies in the real environment 3.
    The user can thus associate with each virtual extinguishing device which he has the impression of entering in the virtual environment, a corresponding fictitious extinguishing device and actually entered in the real environment and he then associates with the device d 'virtual extinction which he has the impression of grasping in the virtual environment impressions of dimensions, shape, mass, position and orientation which he really feels by the real grasp of the extinction device fictitious' corresponding in the real environment.
    The immersion effect in the virtual environment is therefore even more realistic for 1 / user.
    The computer 4 is also functionally connected to said at least one actuator Al of the first dummy fire extinguisher device D1 to know ^ A current state in which this at least one actuator Al is found among its active and inactive states /.
    The computer 4 is also linked: functionally to each of the actuators A2, A3, A4, AS in order to know · a current state in which each of these actions is located among their active or inactive states respectively.
    The state in which an actuator A1, A2, A3, A4, AS is located may be the active state or the inactive state or possibly a partially active state indicating a degree of actuation of the actuator.
    The actuator A1 of the first device Dl comprises a first sensor adapted to measure a value representative of a displacement of a movable part of this at least one actuator Ai relative to another mechanical element of the first dummy device Dl.
    The computer 4 is adapted to command the display device 2 to display in the virtual environment image a virtual flow 7 of extinguishing agent leaving the virtual lance Lvl when said at least one actuator A1 is in active state.
    The computer 4 is also suitable for varying the orientation of the virtual flow 7 in the image of
    The virtual environment IM as a function of the estimated current orientation of the dummy lance L1 in
    The real environment 3 /.
    The calculator 4 is also adapted so that when said at least one actuator Al is in -active state then the virtual lance ^ Lvl is represented without said f lux vit3064801 kills! 7 emerging from the virtual lance.
    Preferably, the computer is also adapted to vary the dimensions of a virtual flow 7 in the virtual image IM as a function of said value measured by the first sensor.
    Likewise, each actuator A2, A3, A4, AS of each dummy device of the system which is functionally connected to the computer 4 uses a sensor which is specific to it - to measure a value representative of a movement of a movable part of this given actuator A2, A3, A4, AS with respect to another mechanical element of the corresponding dummy device D2 ;, D3, D4, D5.
    Each of these sensors communicates with the computer 4 to inform it of the values measured by the sensors via a wired or wireless communication network.
    In this case, a movable part can be a trigger · or a lever movable relative to a handle of the dummy device Dl, D2, D3, D4, D5, this handle being for example mounted on the lance or on a dummy body of extinguishing agent. Thus, each actuator Ai to A5 is controlled manually via a lever or a trigger carried on the corresponding dummy fire extinguishing device.
    We note that one of the dummy devices DS is a lance supposed to be connected to an armed network. To this end, this dummy device D5 comprises another actuator A6 connected to a dummy cocking cock of the device D5 which can be manipulated by the user to switch this actuator A6 between active and inactive states. This actuator is ans30 if associated with markers so that its position in the real environment is estimated and that the computer 4 can command the display of a co-res representation 3064801 in the IM image of the environment. virtual.
    The functional links described in the present application can be wired or wireless with a preference for wireless links between the sensors and the computer and between the display device 2 and the computer 4.
    To further improve the realism of the simulator Ï, it is possible to ensure that the computer 4 is functionally connected to a base of states indicating for some at least devices · dummy extinction · given · Di, D2, D3, Dl, D5 detected by the computer, a maximum authorized duration of action specific to this given artificial extinguishing device.
    • This is applied · to all DI, D2, D3 devices,
    D4 which have a body supposed to contain a limited volume of extinguishing agent. This does not necessarily apply to a D5 fire hose connected to an armed network permanently supplied with extinguishing agent.
    From the computer counts down, for each dummy extinguishing device given Di, D2, D3, D4, D5 detected by the computer 4, a total duration where the actuator A1, A2, A3, A4, AS of this extinguishing device is in the active state and when this · total duration passes the maximum time specific to this device of dummy extinction · given, then the computer 4 commands the display device 2 to represent the virtual lance Lvl of the corresponding virtual extinction device sam said virtual flow 7 leaving this virtual launcher and this even if the actuator of the given dummy device DI, D2, D3, D4, D5 is still at
    The active state.
    User U then knows that he has consumed all the virtual quantity of extinguishing agent allocated · to the virtual extinguishing device which he uses in the virtual environment.
    Knowing the descriptive characteristics of the virtual flow 7 and of the virtual fire 6, the computer 4 estimates whether the virtual flow 7 received on the virtual fire 6 was sufficient or not to extinguish this virtual fire 7.
    If the computer deduces that the virtual fire is extinguished then it commands the display of the image of the virtual environment without virtual fire.
    Conversely, if the computer 4 deduces that the virtual light 6 should not be extinguished, then it controls the display of the Image of the virtual environment with a virtual light 6.
    If the virtual light 6 is extinguished on the IM image displayed, then the user can consider that he has successfully completed the exercise and a sound signaling this success can be generated by loudspeakers 2 b preferably carried by the device d 'display 2.
    Conversely, if the virtual fire 6 is still present in the image of the virtual environment IM then ·, the user U knows that he has failed the exercise or that he must continue the exercise at using another virtual extinguishing device present in the virtual environment and associated with another artificial extinction device Di, D2, D3, D4, D5 present in the real environment.
    In a preferred embodiment of the invention, the calcuiatéür 4 - is functionally coupled to a database · of environments containing groups of data distinct from each other, each group of data given, when it is executed by the computer, induces the display of images: of a virtual environment specific to this given data group and different from images of the virtual environment specific to another of said data groups -from * the database .
    the calculator is also coupled to a means of selecting the data group to be executed by the calcu5 lateUr. Thus, the user can project himself into different virtual environments where he will always see the same virtual fire extinguisher devices which correspond to the devices DI to D5 placed in the real environment.
    This makes it possible to confront the user with different sites previously registered while he has not changed his real environment.
    The real environment can be a meeting room of around ten square meters while the virtual environment displayed can be a kitchen where there is an oil fire (as in Figures · 2 and 3) or a factory or there is a burning electrical cabinet * (as in Figures 4 and 5).
    The simulator 1 according to the invention can also be used to confront the user with different fire scenarios.
    We know for example that there are several classes of real fires including fires:
    - Class A (solid matter fire, generally of an organic nature, the fuel being for example paper, wood, natural textile, vegetable cardboard);
    - class B (fires of liquids or liquefiable solids, the fuel being for example a hydrocarbon, alcohol, solvent, paraffin *, polystyrene);
    - class * G ('gas fires *, the fuel being for example natural gas, propane, butane, LPG, acetylene);
    - class D (metal fires, the fuel being for example iron filings, aluminum powder, uranium, sodium, titanium );
    - of class E (fires of cooking auxiliaries, the fuel is, for example, an oil / fat of animal or vegetable origin associated with a hedgehog apparatus);
    - classy electrical fires of live electrical equipment or installations.
    We know that there are also several types of corresponding extinguishing agents:
    - Spray water to deal with class A fires and not before be used for Class B, G-, D, F, electric fires
    Water plus a spray additive to treat class A and possibly class B and not to be used · for class C, D, F, electric fires;
    A versatile powder to treat class B , C and possibly A lights, and must not be used for · class D, F or electric fires;
    - Carbon dioxide (GO2 ) To treat class fires B, C, F and electric and possibly for class A fires where embers can cause a resumption of fire;
    A specific powder (sand, cement, earth) to treat only fires of classes B (tablecloth) and D,
    In the as part of a realistic simulation, it is therefore desirable to confront the user with several scenarios where he will have to recognize the class of fire associated with the virtual fire., choose the dummy extinguishing device best suited to this fire and finally use this dummy device so that the corresponding virtual device in the virtual environment is properly directed to the virtual fire to extinguish it.
    To this £ in r it is · proposed according to a preferred embodiment of the invention that the computer 4 is coupled to a database · of several predefined scenarios nia, each of these predefined scenarios being such that, when it is executed by the computer 4, the computer 4 generates in the virtual environment displayed, a scenario sequence specific to the scenario executed and varying according to the identity of the dummy extinction device identified by the computer (using by means of its identification by the computer ·) and whose actuator A1, A2, A3, A4, A5 is actuated manually by the user (U).
    Thus, the scenario executed by the; calculatenr 4 évo15 read differently depending on whether the user actuates an actuator of a dummy extinguishing device having a first identity rather than the actuator of another of the dummy extinguishing devices having a different identity.
    This characteristic of the invention makes it possible to adapt
    The scenario taking place in the virtual environment to phenomena · real on real fire which depend on the nature · of the real device · of extinction and of the extinguishing agent which it contains.
    More particularly, the unfolding of the scenario specific to the scenario executed can imply a minimum duration of projection of Virtual flow 7 of extinguishing agent on the virtual fire 6 before the extinction of this virtual fire &, This minimum duration of projection can be variable at least in function of the identity of the dummy extinguishing device actuated by the user and preferably according to the orientation of the virtueXle lance with respect to virtual fire displayed in the virtual environment and / or preferentially according to the position of the lance virtual versus virtual fire displayed in the virtual environment.
    Each scenario in the scenario base defines at least one type of virtual fire to be extinguished (with its class of fire) and several given virtual extinguishing devices made available to the user in the virtual environment :, each of these virtual extinguishing devices corresponding to one of the dummy extinguishing devices present in the real environment and identified by the calculator.
    Ideally, the effect of a stream 7 projected into virtual 1'environnement is defined by the computer according to a predetermined knowledge base to which: the computer is operatively connected. The knowledge base indicates the characteristics of each dummy extinguishing device identified by the computer, in this case at least its maximum duration of use, if possible, a type of extinguishing agent chosen from the aforementioned types and possibly shape characteristics of the flow generated, an optimal range of use distance from a light.
    According to the chosen scenario and according to the Characteristics contained in the knowledge base, the calculator displays in the virtual environment representative effects: of a similar real situation.
    Thus, if the fire treated is a class B fire (oil fire) and the dummy extinguishing device used by the user is of the water type, the calculator as indicated in the knowledge base: will display projections oil and splashes implying a risk of accident.
    Conversely, if the user uses a dummy fire extinguisher of the multipurpose powder type ·, the calculator will display a flame which is gradually reducing, and the creation of a cloud of laying eggs (very reduced visibility) '.
    Reference will now be made to FIG. 6, the typical course of a simulation session using the simulator according to the invention.
    In step E1, the constituent elements 10 of the simulator are installed in any room such as a meeting room (the computer, the devices D1 to D5, the video headset and the optical sensors f cameras and markers are positioned).
    In step E2, the user 0 is equipped with the videocasque 15 and gloves or straps carrying the markers on the hands. The positions and orientations of the different markers and the states of the different actuators in the real environment are estimated by the computer. The respective identities of the dummy devices are also detected. A session scenario is selected from a scenario base.
    In step E3, an image of a virtual environment IM is projected onto the video headset and the user is immersed in the virtual environment selected in the scenario base;
    In step E4 the user sees:
    - virtual hands in positions and orientations representative of those of his real hands;
    - the room in the virtual environment with its constituents (cardboard stock, office, boiler room, electrical cabinet, etc.);
    - virtual extinguisher devices which horns 3064801 lie against the artificial devices present in the real environment (water extinguisher, CO2, powder ...); and eventually·
    - a virtual emergency stop.
    In stage ES, a virtual fire is generated in the Virtual environment according to the selected scenario.
    In step E6, the user uses one of the dummy devices of the real environment to select a corresponding virtual device in the virtual environment and then operates with the aid of his actuator.
    If the selected virtual device is not the right one according to the scenario, then we are in step E7a.
    In step 7b, the user actuates the actuator of this device and observes ·· in the virtual environment a projection of flow 7 of extinguishing agent in a direction determined according to the orientation given to the lance in 1 real environment. The effects of this projection are displayed according to predefined effects in the knowledge base (flame attenuation, flame displacement ·, explosion, powder cloud, etc.).
    In step E10 the virtual fire is not extinguished. According to the scenario, the user notices in the virtual environment damage associated with the choice of the wrong extinguishing device, an increase in flames, · a resumption of fire.
    In step E8 the user activates only an emergency stop visible in the Virtual environment and depending on the scenario, this leads either to step E10 or the fire is not extinguished or to step E9c where it is considered that this action is sufficient to extinguish the virtual fire. 'Here the emergency stop can activate an automatic fire extinguishing system and / or an audible alarm via the loudspeaker 2 b.
    It should be noted that: sound means connected to said computer 4 can generate a sound environment for the attention of the user which corresponds to the progress of the scenario.
    In step E9a, the user has chosen the right device, that is to say one whose type of extinguishing agent corresponds, according to the knowledge base, to the virtual fire class defined in the scenario base .
    In step E9b, the user actuates the actuator of the chosen device and a virtual flow is displayed, as previously described with reference to step E 7b.
    In step E9c, a duration is counted: of projection on the virtual fire. If the debt duration is insufficient and / or if the position and orientation of the f lux are not suitable: according to the knowledge base for this virtual traffic light, then, we go to: step EIQ where the virtual traffic light remains displayed.
    Conversely, if the projection duration is sufficient: and if the position and the orientation of the flow conform to the knowledge base for this virtual fire then we go to step Ëll where the fire is extinguished.
    The simulation is a success and the user has the feeling of having lived: and treated correctly a real fire.
