Definitions

• the present invention relates to a method and a device for remotely collecting data from aircraft or ship recorders.
• the field of the invention is therefore that of the safety of air or sea transport.
• the invention relates to an ejection buoy from an aircraft or a ship when the latter is in distress.
• VDR voyage Data Recorder
• the invention thus relates to the remote collection of data from recorders of aircraft, ships or submarines inhabited or not.
• the object of the invention is to enable a reconnaissance aircraft, in a single flight, to bring back the data of the recorders as well as the precise coordinates of the point of sinking while driving in parallel and without interruption the search visual floating debris drifting.
• the collection of data requires the recovery of the recorder at the sea surface, either by a ship sent to the area or by helicopter using, for example, a device such as that described in US Patent 5,086,998.
• This operation can not be conducted by a fixed-wing aircraft such as an aircraft of recognition that alone has the radius of action allowing it to reach any area of the ocean.
• US Pat. No. 4,981,453 describes a warning buoy and a guide for rescue means. It does not include a data storage device and therefore does not allow the remote collection of data from recorders.
• the present invention therefore has the main purpose of solving the difficulties presented by the methods and devices of the prior art by proposing a method and a device for remote data collection of aircraft or ship recorders.
• the invention proposes a device for remotely collecting data from aircraft or ship recorders, characterized in that it comprises an ejection buoy equipped with a bidirectional radio channel making it possible to ensure digital data exchanges with a remote data collection means, this buoy being provided with a satellite location receiver and a local memory in which its successive positions are stored during its drift to the surface of the sea, said buoy further comprising a memory in which are stored, prior to its ejection, information such as those stored in flight recorders for aircraft, or travel for ships, said buoy also comprising a power source and a device onboard electronic sound activation.
• the method of remotely collecting data from aircraft or ship recorders according to the invention is remarkable in that it comprises the following steps:
• FIG 1 is an overview of the device according to the invention.
• FIG. 2 represents a functional block diagram of the subsets of the ejection buoy.
• Figure 3 shows a block diagram of the remote data collection equipment.
• FIG. 1 shows an overview of the device.
• An aircraft 1 is damaged on the seabed. Near the point of impact 2 of said aircraft with the surface of the water is illustrated a buoy 3 drifting surface after its ejection of the aircraft. Its position 4 at the time of the radio session with the remote means is representative of its drift after its ejection.
• the geolocation satellites 5 allow the buoy to record at regular time intervals, its drift 6.
• different means of communication with the buoy 4 at a distance such as a maritime patrol aircraft 7, a communication satellite 8 and its control station installed on land 9 or on a ship 10.
• the reference 1 1 designates a satellite dedicated to the location of distress transmitters forming part of an international network such as the COSPAS-SARSAT system.
• the remote data collection means may also be constituted by a fixed or rotary wing aircraft, a communication satellite, a periscopic immersion submarine.
• FIG. 2 which represents a functional block diagram of the subsets of the ejection buoy, is represented a source of electrical energy such as a battery, a central unit constituted by a microprocessor, a device for energizing the internal electronic buoy at the end of the ejection.
• This activation device 22 may consist of electrodes detecting contact with seawater or an activated contactor during ejection.
• a first memory 23 nonvolatile information is recorded which is characteristic of the flight or journey, received via an interface 24 inside the buoy and a communication electronics 25 provided, if necessary, with an external device for encrypting the data. .
• the data from a satellite location receiver 27 passes through the microprocessor 21 to a second memory 28 where the drift of the buoy is stored since its ejection, if necessary in encrypted form using the internal circuit 32.
• radio transmitter 29 serves to communicate with the remote means of data collection. On receipt of orders, it securely transmits the contents of the memories 23 and 28.
• the buoy may be provided with a distress transmitter 30 set on the international frequencies of a distress transmitter locating device, facilitating thus its detection and identification very quickly from a center on the ground.
• a flash lamp 31 may be activated at dusk for a visual location of the buoy by an overhead or surface means such as a ship.
• a test interface 33 is used to verify in the workshop or in flight the proper operation of the electronics inside the buoy.
• the various components mentioned are integrated into a shockproof sealed enclosure 36 providing buoyancy by buoyancy.
• An optional remote controlled device 34 makes it possible to scuttle the buoy once the contents of its memories have been transferred remotely.

It comprises a computer 40, powered by a source of electrical energy 41, which communicates via a radio transmitter 42, with the buoy. The communications being direct or relayed if necessary by one or more satellites 8.

• a reconnaissance aircraft may, in a single flight:
• the buoy does not make spontaneous emissions. As a result, it can not be located by an undesirable third party who, after having retrieved it, will subtract the content from those for whom it is intended.
• the data stored in the memories 23 and 28 can be encrypted using the device inside the buoy 32 or external 26, the recovery of the buoy by a third party does not allow it to operate unauthorized.
