    The field of the invention is that of signaling an immersed object at the bottom of a liquid medium which is traditionally on the surface and allows the recovery of the submerged object, this buoy being connected by a cable to said object. The invention relates more particularly to the fact that the buoy is secured to the object and is therefore not visible from the surface, and that its ascent is triggered from the surface by a remote control emitting ultrasound carrying a code.
    2. TECHNOLOGICAL BACKGROUND
    It is often useful to immerse an object in the sea for a fixed period, such objects are often used for fishing for crustaceans, cephalopods or fish, or even scientific devices. Once submerged, the object and the so-called recovery buoy became more visible.
    The law requires surface signage indicating the registration of the ship, but some rare users do not do so, or even register false registrations, and collect objects either to steal the animals they contain, or to steal the object himself.
    One way to avoid having the object stolen is to no longer be able to pick up the submerged object. The orin may have been cut by the propeller of a motor boat, belonging for example to a competitor of bad time. The orin may also have been caught under the rudder of a sailboat which loses control of the ship. If the object is connected to a signaling buoy, it is connected to the object by a thin and therefore breakable line, it can also be connected to the object by a device which will cause it to break without raising the object immersed. A patent application FR 2 950 318 has already been filed by the applicant, describing an operation where the buoy is raised automatically. In this request, it is described that the object at the bottom of the water has an electronic box containing a device which releases the submerged buoy and makes it rise to the surface following the programming of a date and a ascent time. This programming is binding on the user. This device includes an electromagnet which, when it receives an electrical signal, unlocks a plate to which the buoy is attached.
    In a first embodiment, the buoy is released at a very precise time of the day and its owner knows that he must be above his object at this time and awaits its ascent. Once on the boat, the user hangs the buoy on the object and returns the assembly to the bottom of the water.
    In a second embodiment, and as illustrated in FIG. 1, the buoy is released using a transmitter and a receiver instead of the clock. In this case, a transmitter placed for example under the hull of the user's boat or in a remote control can send a signal, for example ultrasonic, to a receiver placed in the support, which will act on the box to temporarily deactivate the electromagnet and thus release the buoy.
    A disadvantage of this known solution is that anyone with an ultrasonic transmitter can release the buoys.
    It is therefore important to provide increased security to the current system in order to more effectively select the buoy to be released.
    3. STATEMENT OF THE INVENTION
    In a particular embodiment of the invention, there is provided a system for releasing a buoy comprising a housing fixed to an object immersed in a liquid medium, said housing comprising a release means controlled by an electrical release signal in order to to separate the buoy from the submerged object and make it regain the surface of the liquid medium. The system further includes at least one remote control having an ultrasonic wave transmitter, said housing comprising an ultrasonic wave receiver transmitting the release signal upon receipt of a determined code transmitted by the ultrasonic wave.
    In this way, a user can control the release of the buoy from the surface using a remote control emitting a code which is recognized by the submerged object.
    It can be noted that this triggering using ultrasonic waves allows an original use of protection of forages anchorages. Indeed, it often happens that vessels either passing through, or going for a walk, or reserved for fishing, find on their return occupied anchorages, which is illustrated by the left part of Fig.1. These moorings are generally connected to the attachment buoy connected either by a strong rope, or by a chain fixed on a large block of a few hundred kilograms. It is planned to connect the upper end of this rope or chain to the buoy and its lower end to an ultrasonic receiving device. In this way, and as shown in the right part of FIG. 1 illustrating the prior art, the owner upon his return triggers the ascent and recovers the object by the orin or the chain as the case may be.
    A signaling buoy is possibly planned and connected to a weak rut with the large pavement of a few hundred kilograms, which prevents opportunistic people from settling there.
    According to a first embodiment, the remote control comprises a geolocation means (GPS) and a memory registering its position following the introduction of a user command, each recorded position is associated with an identifier of the object submerged at this position. In this way, the user can easily find the location of the place where the object to be reassembled is immersed.
    According to another embodiment, the remote control comprises a software module comparing its current position and a stored position of an object selected by a user command, the remote control comprising a screen displaying the direction to take from the current position to reach the position of this object. In this way, the remote control can easily guide the user to reach the place where the object to be wound up is immersed.
    According to another embodiment, the system comprises a computer, preferably on the ground, communicating with the at least one remote control in order to receive a list of at least one identifier of immersed object associated with at least one position, the computer with a means of duplicating said list in another remote control. In this way, if a remote control is lost, it is easy to duplicate the data in another.
    According to another embodiment, the box comprises a means of bidirectional and short-range communication, of an inductive nature for example, with the at least one remote control, and by this means communicates an identifier of the immersed object to the remote control which inscribes it in a memory. In this way, the computer pairing between a remote control and a submerged object is easily carried out.
    According to another embodiment, the transmission of the identifier of the immersed object to the remote control triggers the memorization of this identifier in association with the current position of the remote control. In this way, the manipulations carried out by the user are simplified.
    According to another embodiment, the submerged object communicates to the remote control the electrical level of its battery, the remote control displaying this level on a screen. In this way, the user is informed of the state of the battery of the submerged object and can decide to replace or recharge it.
    According to another embodiment, the remote control comprises a clock and a means of memorizing time information by associating it with at least one identifier of a submerged object, the association is memorized during the introduction of a command. user, the remote control or a device in communication with it displaying the history of stored data. In this way, the user can know how much time has elapsed since the object was last reported and know a history of the reports for each object.
    According to another embodiment, the communication of the identifier of the immersed object to the remote control triggers the memorization of the time information. In this way, the manipulations performed by the user are simplified, because the system is responsible for entering time data.
    According to another embodiment, the remote control or a device connected to it records in a memory a plurality of battery levels measured during a certain period and, by calculating the evolution of the level of this battery, emits a signal d alarm when the level evaluated at a given instant is below a determined threshold. In this way, the user can predict that the next time a certain object is raised, it is necessary to change the battery.
    According to another embodiment, the system comprises a plurality of boxes fixed to as many submerged objects, each box having a code different from the other boxes to release their buoy, the system also comprises a special remote control emitting by ultrasonic wave a code special triggering the release of buoys from all objects of plurality. In this way, maritime authorities can trace all objects from the bottom of the water for inspection.
    According to a first embodiment, the release of the buoys is carried out after a time delay starting upon receipt of the special code by the object, said duration being different for each object of the plurality. In this way, upon reception of the signal from an apparatus of an authority, all the objects do not trigger the ascent of the buoy at the same time, preventing the orins from becoming tangled.

    5. DETAILED DESCRIPTION
    In all the figures in this document, identical elements are designated by the same reference numeral.
    5.1 ____ General_ Principle
    The invention relates to a buoy release system comprising a housing fixed to an object immersed in a liquid medium and at least one remote control fitted with an ultrasonic wave transmitter. The housing includes a release means controlled by an electrical release signal in order to separate the buoy from the submerged object and make it regain the surface of the liquid medium. The housing includes an ultrasonic wave receiver transmitting the release signal on receipt of a determined code transmitted by said ultrasonic wave. In this way, a user can control the release of the buoy from the surface using a remote control emitting a code which is recognized by the submerged object.
    5.2 ____ Preferred mode of realization
    We now present, in relation to FIG. 2, a system for releasing a floating object such as a buoy, normally attached to an immersed object at the bottom of a liquid medium, typically a river, a sea or an ocean. Care will be taken to size the buoy so that the buoyancy of the assembly formed by it and the object remains clearly negative, so as to remain at the bottom of the water. The submerged object 1 is for example a trap for capturing animals, or fixed on research tools at the bottom of the water. Scientists can also use this system to study the state of certain marine resources, such as cephalopods, fish, crustaceans, the effect of pollution, etc. A buoy 2 is normally fixed on a support secured to this object using a so-called polar plate attached to a very short link 3 and is therefore not visible from the surface, this buoy is also attached to the object by a cable 4, its rope or tip in sailor's language, long enough to allow it to rise to the surface while leaving the object at the bottom. One of the aims of the invention is to separate the buoy from the submerged object to allow it to return to the surface of the liquid medium, while remaining attached to this object by the cable and thus signal the position of the object on the surface. The buoy is released using a remote control held on the surface by a user, for example a fisherman in his boat, the remote control emits an ultrasonic wave carrying a determined code. The ultrasonic wave is received by a housing 6 fixed to the submerged object, and if the code carried by this wave corresponds to a value memorized by the housing, then the housing releases a plate 7 serving for attachment to the short link 3. Following Archimedes' principle, the buoy 2 then rises to the surface with the plate 7 while remaining attached to the object 1 by the cable 4. In this way, the submerged object is signaled on the surface at the request of 'a user and the fisherman can by pulling on the buoy 2 and on the cable 4, reassemble the object from the surface. After working on the object, the user hangs the plate 7 to the housing and release the assembly which descends to the bottom. In this way, the release system is reversible and between two lifts, the object and its buoy remain perfectly invisible on the surface.
    This system can also be used to signal underwater archaeological excavations, divers arrive by boat on the presumed area where an object, typically a gueuze, is immersed and activates the remote control. The buoy appears on the surface and serves as a reference. The cable 4 can advantageously be used to help divers descend to the place where the object is located. Before their ascent, the divers pull on the cable 4 to immerse the buoy and hang up the plate 7 to the housing 6.
    According to an improvement, the object is signaled on the surface by another buoy 8, called a signaling buoy, which is attached using another end 9. The attachment of this end 9 to the object 1 is designed to be break if a person on the surface pulls on the tip to raise the object. In this way, a malicious person cannot recover the object if he does not have the remote control enabling the first buoy to be released 2. Advantageously, a ballast 10 is fixed on the end 9 a few meters from the attachment on the object, the test coming to land at the bottom of the water at a certain distance from the object. In this way, the signaling buoy is not on the surface exactly above the object but is offset, and thus a malicious person descending a hook vertically from the signaling buoy, could not raise the submerged object 1.
    Fig. 3 shows an example of a diagram of the various electronic components of the box attached to the submerged object.
    The box 6 includes in particular the following elements:
    a Control Unit 20 (UC), typically a microprocessor and its associated program memory 21,
    - a non-volatile data memory, for example Flash memory or EEPROM,
    - an ultrasonic wave receiver 23 connected to an ultrasonic earpiece 24 whose membrane is in contact with the environment outside the housing,
    a battery 25, associated with a means of measuring its voltage,
    a short-range means of communication 26, for example an inductive link (this element being optional),
    - A release means 27 releasing the plate 7 by supplying an electromagnet 28. Such a means is already described in application FR10 53689 filed by the applicant and therefore does not need to be explained further.
    According to a preferred use of the system, the box 6 is intended to be immersed in water, and in particular in salt water. It must therefore both resist pressure and corrosion in the marine environment. In order to guarantee a longer life for the battery 25, the control unit 20 is woken up at regular intervals, typically every two seconds and activates the ultrasonic receiver 23 in order to detect the possible presence of ultrasonic waves in the medium. liquid. If there are no such waves, the control unit immediately goes into standby mode. Otherwise, the control unit demodulates the signal carried by the ultrasonic wave received in order to extract the computer code therefrom. This computer code is then compared with a data item stored in the memory 22, and in the event of a tie, the control unit 20 emits an electrical signal by means of release 27, which has the effect of powering the electromagnet 28 a short time and release the plate 7. In this way, the release of the buoy 2 is carried out with a certain level of security.
    According to an improvement, the code transmitted by the remote control is encapsulated in a computer data item modulated within the ultrasonic signal, and the data item is encrypted. In this way, the system provides increased security.
    Fig. 4 shows an example of a diagram of the various electronic components of the remote control usable on the surface. According to this exemplary embodiment, the remote control comprises the following elements:
    a Control Unit 30, typically a microprocessor and its associated program memory 31,
    a non-volatile data memory 32,
    a possibly remote user interface 33, comprising a means for introducing commands 34 (specialized keyboard, keys dedicated to certain functions, microphone associated with a voice recognition system, etc.) and data display means 35 ( screen, electroluminescent display, ...). Alternatively, the remote control has a touch screen,
    - an ultrasonic wave transmitter, this transmitter consists of an electric amplifier 36 placed in the remote control 5 and a wave transducer 37 at the end of an electric cable. In this way, it is possible to place the ultrasonic wave transducer in the liquid medium, under the hull of a boat for example, as shown in Fig. 2,
    a battery 38, associated with a means of measuring its voltage,
    - A short-range communication means 39 allowing at least to communicate with the communication means 26 of the housing 6, this element being optional. Communication can be initiated by bringing the remote control close to the box 6, or by pressing a button. Advantageously, this means of communication 26 can also communicate with the navigation system of a boat, and / or with a computer on the ground,
    - a geolocation means 40, for example a reception module of the GPS system (from the English “Global Positioning System”), this element being optional,
    - a means of determining the time and date 41, a clock or a radio receiver receiving this type of information, this element being optional.
    According to a preferred use of the system described in FIG. 2, the remote control 5 can be used in a small boat. According to a variant, the remote control uses the boat screen as a display means 35, which in particular makes it possible to display information on a larger screen surface.
    The user activates the remote control 5 and selects a code corresponding to that memorized in the memory 22 of the submerged object 1. Then, the user presses a button for transmitting an ultrasonic wave carrying this code. The wave emitted by the remote control is then received by the box 6, and if the code transmitted corresponds to a data recorded in the memory 22, then the plate 7 is released and the buoy 3 returns to the surface.
    5.3 ____ Improvements_in_the_development modejjreferred
    According to an improvement, the remote control and the box communicate together by a bidirectional short-range link. In this case, just before submerging the object 1 for the first time, the user establishes communication between the remote control and the box, the code is then read from memory 22 and is duplicated in memory 32 of the remote control . In this way, the user does not need to enter it on the keyboard of his remote control, the first time he puts the object in the water.
    According to another improvement, the remote control has a geolocation module 40. In this case, each time the user indicates on the keyboard that he is close to an object, the remote control interrogates his geolocation module 40 to determine the position of this object and saves it in memory. In this way, the remote control knows the locations of all the objects for which it has the codes, and can help the user find them. Advantageously, each time the user reassembles an object, he first establishes communication between the remote control and the box. Communication begins by reading the code in memory 22 of the box so that the remote control determines what object it is. In this way, the user does not need another command entry to identify the object, simple communication with it is enough.
    According to another improvement, the remote control has a means of determining the time and the date 41. In this case, each time that the user indicates to the remote control that he is near an object, for example because it has just been reassembled, so the time of this event is recorded in memory. Advantageously, the simple fact of establishing a two-way communication between the remote control and the box triggers the acquisition of the date and time and its association with the object which has just been raised from the bottom of the water. In this way, the user can know the frequency of the visits he makes to each object.
    According to an improvement, the remote control manages in memory 32, an array of parameters associated with each submerged object, here is an example of such an array:
    Number, Type Contact information Time and date of Voltage (Coded) of object Object GPS last immersion assessed 1 (aaa) VS (xxlL, yy 11) H / D 50% 2 (bbb) VS (xx2L, y y 21) H / D 20% 3 (ccc) B (xx3L, yy31) H / D —S% -
    The type of the object is defined by the user, such as: a lobster trap, or a submerged net, or any other particular point that the user needs to locate. By pressing a button on the remote control, the user displays the content of the table and can therefore know at any time the parameters associated with each object. By visually observing that the date of the last immersion is old, he can thus decide to raise this object from the bottom of the water. He then goes to the location determined by the geolocation coordinates, using for example the navigation system of the boat, and arriving at the specified area, triggers with the remote control the release of the buoy. By then pulling on cable 4, the user removes the object and triggers communication between the box and the remote control again, which has the effect of updating the table.
    According to another improvement, the remote control is provided with wired or wireless communication means with a computer, preferably on the ground. Using this means, the computer receives from a remote control a list of at least one immersed object identifier associated with at least one geolocation position. Once this data is in memory, the computer can duplicate it in another remote control. In this way, if the user loses a first remote control with all their data inside, they can transfer this data to another remote control.
    Specific examples of the display menu will be presented below. Fig. 5 shows a diagram of a screen appearance present on the display of the remote control according to a particular embodiment. In this example, the remote control has a geolocation module 40 activated. During a previous trip to the sea, the user immersed several objects referenced "1," 2 "and" 3 "at locations identified by their geolocation coordinates. These coordinates were, for example, introduced by reading the geolocation module 40 during immersion and recorded in memory 32. The menu illustrated in FIG. 5 shows a map of the location of the remote control currently represented by the drawing of a boat and the positions recorded in memory 32. In this menu, it can be seen that three objects referenced 1, 2 and 3 have been immersed , and that the remote control is located approximately in the middle of these three objects. By taking a course, the user can easily reach these coordinates and trigger the release of the buoy. The menu advantageously shows certain parameters associated with each immersed object, such as the date and time of the last immersion. In this way, the user has relevant elements to select the object he wants to reassemble. In addition, by using such a remote control, the user no longer needs another navigation device, he can be guided by it.
    According to another improvement illustrated by FIG. 6, the remote control records over time all the voltages of the batteries 25 measured by the Control Unit 20 and transmitted by the communication means 26. By taking into account the characteristics of the battery, it is possible to determine the evolution of the remaining capacity as a function of time. In Fig. 6, 4 voltages were noted at times tl, t2, t3 and t4, and the corresponding capacities were calculated. At the current time ta, the remote control can therefore assess the capacity at this time of the battery, and can also determine when "110%" this capacity will drop below a certain threshold, 10% for example. If the remote control detects that one of the submerged objects whose parameters are saved in its memory, sees the capacity of its battery drop below this threshold, then it emits an audible and / or visual signal informing the user of this fact. . At the sight of such a signal, the user can go to the place where the object is immersed, reassemble it and change its battery. In this way, the remote control alerts its user when the battery is at the end of its life, and that soon it will no longer have enough energy to pick up the ultrasonic waves and trigger the release of the buoy.
    According to another improvement, when the box 6 detects that the battery voltage is very low, corresponding to a minimum capacity level (5% for example), it automatically triggers the release of the buoy 2. In this way, whatever 'it happens, the object can always be reassembled.
    Fig. 7 shows a diagram of a remote control used as a prototype for the tests. This remote control has a rectangular screen showing the parameters associated with each submerged object, where a menu similar to that in Fig. 5, or a configuration menu for, for example, testing the geolocation module or setting the date and time. The battery level of the remote control is displayed by a light bargraph at the bottom right. The keyboard of this remote control has the keys:
    - an on and off button,
    - a button for selecting a code, this code is carried by the ultrasonic wave and identifies the submerged object, the code is preferably referenced by a number which is constantly displayed on the screen once selected,
    - a button for transmitting the ultrasonic wave carrying the code previously selected and the number of which is displayed,
    - an operating mode selection button,
    - a button for activating the geolocation means (if it is implemented), and
    - a button for determining the current position.
    5.4 ____ Use_of_universal_code
    In some cases, an administrative authority more commonly known as "the
    Maritime Affairs ”or the customs service can control the legality of the submerged objects. This provision is notably regulated in France by decree 19900 and article 21 of January 25, 1990, as well as ordinance n ° 2010-462 of May 6, 2010. They should therefore have as many remote controls with the same codes as those used by all users, which is almost impossible. The solution therefore consisted in providing a special code, managed by devices using an additional channel (called “fifth” channel in the prototype produced) accessible on a special remote control, having a high level of security, and which triggers the release of the buoy in all cases. Suppose for example the case illustrated in FIG. 5 where three objects 1,2 and 3 are immersed. Each box 6 has its own code and releases the buoy only upon receipt of this code by an ultrasonic wave. As part of this improvement, each of these three boxes also has a fourth code, which also triggers the release of the buoy. In this way, certain duly authorized authorities can raise the buoys and thus inspect the objects.
    Bringing up all the submerged objects present in the same area and which may possibly belong to different users, can entangle the cables 4. To avoid this phenomenon, and according to an improvement, the release of the buoys takes place after a time delay starting when the special code is received by the object, the duration being different for each submerged object. Duration is for example defined by the result of a mathematical function whose variable is the object code. According to a variant, the duration is calculated using a random number generator.
