Definitions

  • the present invention relates to a device for rescuing a person who has fallen from a nautical vehicle and, more particularly, to such a device of the type which includes emergency means on board the vehicle and designed to be launched. under the control of a radio signal automatically transmitted by a transmitter, such signals incorporated in an alarm box worn by the person, when the latter arrives in the water.
  • the present invention therefore aims to achieve such a device for locating the person overboard so as to allow a quick recovery of it.
  • the present invention also aims to provide a device for rescuing a person overboard, the implementation of which is well protected from inadvertent trips.
  • a device for rescuing a person who has fallen from a nautical vehicle comprising emergency means on board the vehicle and designed to be put in the water under the control of a radio signal automatically emitted by a transmitter of such signals incorporated in an alarm box worn by the person, when the latter arrives in the water, this signal controlling means for releasing the emergency means, device characterized in that the vehicle is equipped with a submerged acoustic source for emitting acoustic signals in water and in that the alarm unit also comprises an acoustic sensor sensitive to the signals which propagate in water from the acoustic source to control in response the emission of a radio signal by the transmitter incorporated in this box, this radio signal then being picked up by a receiver eur installed in the vehicle to trigger the means for releasing the emergency means.
  • the emergency means are constituted by a beacon equipped with means making it possible to locate it, which comprise a submerged directional acoustic sensor sensitive to the signals emitted by the acoustic source of the vehicle, a compass, electronic means for processing the signals delivered by the sensor and the compass and radio transmission means associated with these processing means for transmitting signals allowing the location of the beacon, the radio receiver of the vehicle receiving these signals.
  • the emergency means consist of a motorized and remote-controlled emergency vehicle, equipped with a submerged acoustic source, the alarm unit being equipped an acoustic sensor sensitive to the signals from this source and to the orientation of the source to form the remote control signals of the engine of the emergency vehicle, so as to bring the latter closer to the navigator.
  • the acoustic emission source 2 or "pinger” permanently emits acoustic pulses, it is controlled by an electronic module 20 forming part of the box 4 (see FIG. 4).
  • the directional hydrophone used in the measurement head 14 consists, for example, of an association of four sensors crossed at 90 ° giving a signal proportional to the sine of the direction of the received signal and a signal proportional to the cosine of this direction.
  • FIG. 2 of the drawing there is shown the electronic alarm box 6 forming part of the device according to the invention.
  • This box the size of a matchbox, includes an omnidirectional acoustic or hydrophone sensor 16 connected to an electronic module 17 for receiving acoustic signals, this electronic module activating an electronic module 18 for VHF radio transmission.
  • the VHF antenna consists of a collar 19 for supporting the housing around the neck.
  • a power supply 26 completes the housing.
  • control box 4 of the device essentially comprises an electronic module 20 for controlling acoustic emission by the "pinger" 2, an electronic module 21 for receiving VHF associated to the control electronics 22 for releasing the beacon, a microprocessor 23 for calculating in particular the distance of the beacon, and a device 24 for displaying the heading and the distance of this beacon on the box.
  • the power supply 25 of the box is provided either by the on-board network if it exists, or by batteries.
  • the operation of the rescue device according to the invention is then established as follows. If a person equipped with the individual alarm box 6 falls overboard, the hydrophone 16 of this box receives the acoustic pulse emitted by the source 2 and this reception generates a VHF radio signal which is emitted by the antenna collar 19.
  • the radio signal is then received by the antenna 5 of the box 4 which controls the release of the beacon 3.
  • This release is obtained, for example, by the triggering of pyrotechnic means (not shown).
  • a propagation of acoustic waves in the water is used to trigger the release of the beacon 3, propagation which is only detected when the person equipped with the alarm unit 5 has actually fallen into the water. 'water.
  • Such detection is much more reliable than that established by the wetting of electrical contacts, wetting which can occur even when the person is still on the boat.
  • This improvement in the reliability of the detection of the launching of the person is an important advantage provided by the present invention.
  • the tag 3 being immediately and automatically released, it falls into the water in the immediate vicinity of the shipwrecked, which makes it possible to deduce the location of the position of the latter from the location of the location of the tag 3.
  • the present invention is located using the directional acoustic sensor which is located in the measuring head 14 deployed under the beacon to receive the emissions from the acoustic source 2.
  • the directional sensor can thus determine the bearing of the vehicle thanks to the two signals delivered by this sensor, one proportional to sin ⁇ and the other to cos ⁇ , ⁇ being the bearing of the vehicle.
  • the "signal processing" part of the electronic module 15 from the beacon codes the heading information that the vehicle will have to follow to reach the shipwrecked person and transmits the code in VHF to the box 4 of the boat, via the antenna 9 of the beacon and the antenna 5 of the box.
  • Means for measuring the instant (not shown), the emission of the signal by the acoustic source 2 of the vehicle, and the instant of reception of the radio signal emitted by the beacon 3 on reception of the acoustic signal, provide the microprocessor 23 (see FIG. 4) the time interval enabling the latter to calculate the beacon-vehicle distance and therefore the beacon-wrecked distance, this being assumed to be close to beacon 3.
  • the microprocessor then controls the device d display 24 of the heading and the distance of the shipwrecked person.
  • the device may further comprise alarm devices which are triggered simultaneously with the dropping of the beacon.
  • it can be equipped with a flashlight and optionally emit a smoke substance, as optical signaling means of the position of this beacon.
  • the float deployed from the beacon can also be shaped so as to be able to serve as a support on which the shipwrecked person can possibly hang.
  • the beacon could also be fitted with a waterproof loudspeaker and a voice-radio link between the boat and the beacon to establish oral contact with the shipwrecked person.
  • the hull "pinger” is removed and this is the acoustic "signature" of the boat, resulting from all the sources of acoustic emissions present in it, as it is received by the head of the beacon, which allows it to be located, in the direction only.
  • the embodiment described above of the device according to the invention assumes that there are several men on board the boat. To adapt this device to the search for sinking solo sailors, it is possible to provide a rescue boat, a helicopter or other aircraft, with a VHF reception box. If the shipwreck's boat has not sunk, the emergency services sent in search of the lone navigator and having located the boat may find the shipwrecked person in the vicinity of the latter.
  • the individual alarm box includes a directional acoustic sensor capable of operating several meters below the surface of the water and providing, like the beacon of the previous embodiment, the course of an acoustic source.
  • the acoustic sensor is supported by a wire which is unwound by the shipwrecked himself. The presence of this acoustic head obviously increases the volume of the individual alarm box a little.
  • the emergency means on board the lone navigator's vessel is no longer constituted by a beacon but by a small motorized and remote-controlled vehicle which is dropped in the event of the lone navigator falling overboard.
  • This vehicle is equipped with an electric motor controlled from the location signals of the shipwrecked person established in the individual alarm unit by electronics associated with the acoustic sensor and emitted by the antenna of this unit.
  • the vehicle is equipped with acoustic source or "pinger" and a control box.
  • the box receives the VHF signals emitted by the alarm box, these coded signals containing the deposit and the distance of the shipwrecked person.
  • the vehicle engine remote control supplied with this information, then directs the vehicle towards the shipwrecked.
