Description

The invention relates to the field of acoustics, in particular to the emission of hydroacoustic encoded and broadband control signals.

The problem that is solved by the invention is the rapid detection, identification and location on a large area of a sunken object (AO), operational preparation and lifting to the sea surface or towing in shallow water AE, and also in the shortest time to save the lives of people caught in AE.

The method is implemented as follows.

Each moving AO has one or more emergency rescue buoys (ASBs). At the same time, each ASB has a waterproof housing, which excludes flooding of the ASB or its mechanical damage at all depths of the intended area of use. In this case, the required supply of a cable with positive or zero buoyancy, depending on the type of AE, is placed either around the ASB body or in a special container attached to the outside of the AO.

Inside the ASB case there are: blocks for receiving, amplifying and decoding the hydroacoustic encoded signal F _ks , a block for decrypting shock signals from inside the AE, which is connected to the output of the amplification block parallel to the unit for decoding the hydroacoustic encoded signal F _ks , as well as a mechanical disconnector that provides the required cable strength after surfacing ASB to the sea surface, a digital information storage device that provides continuous registration of all signals coming through the receiving and amplification units from the moment it is triggered an ASB hydrostat before the end of rescue operations, a radio transmitter and a high-capacity power supply, charged once a year. On the ASB case are located: a radar antenna, located in the transport version, a hydrostat, a reflector, a reflector of radar signals, a raised beam and a flashing beacon.

After the occurrence of force majeure circumstances and the complete immersion of the air conditioner under water, the hydrostat is activated for the first time and the electric power supply of the corresponding ASB units is turned on. At the same time, all signals coming through the reception and amplification units begin to be continuously recorded on the digital information storage device. Living people who find themselves in the AO begin to give SOS signals by tapping metal objects on the AO body from the inside.

After the acceptance of the control alarm F _sos for the ASB ascent, its amplification and decryption, an electrical control signal is supplied to the mechanical circuit breaker. After operation of the mechanical circuit breaker, the ASB is mechanically disconnected from the body of the AO. Due to its buoyancy and the necessary supply of the cable, previously placed either around the ASB hull or in a special container, the ASB begins to float to the surface of the sea.

A hydrostat is triggered a second time on the surface of the sea. At the same time, the radar antenna, which was previously in the transport version, is mechanically straightened on the ASB case, and ω signals and short-term signals coming from the AO begin to be transmitted to the radio air in a pulsed mode. In addition, the raised beam is triggered and the flashing beacon starts to work, and the reflector of radar signals located on the ASB housing provides effective reflection of radar signals from the navigation radar station.

The information received from the direction finders of search and rescue facilities (PSO) and all search objects (PO), as well as data from other sources, are immediately transmitted to the coastal center. To search for the AO in a given area, the nearest radar stations and software begin to use navigation radar stations, and additionally, the generation, amplification and emission units of the hydroacoustic encoded signal F _cs , as well as the current distance measurement unit, are used on the OSS and on the software part. Visual observation is being strengthened, as well as preparations are being made to use towing and lifting AO devices to the surface of the sea.

In a given area, discrete block of omnidirectional radiation of a hydroacoustic encoded signal F _{x is} dropped discreetly, every 30-50 km, from the SSO and part of the software at the “foot” into the water to a depth of 10-15 m along the cable cable. In the forming unit, a code is set corresponding to the ASB ZO number. In the amplification unit, the code signal F _{cc is} amplified to the required level, and with the help of the corresponding block, the hydroacoustic coded signal F _cc is non-directionally emitted.

Using the reception unit located inside the ASB enclosure, the hydroacoustic encoded signal F _cc is received, which is then amplified to the required level in the amplification unit and compared with the code signal in the decoding unit of the encoded signal F _cc . If the code matches, an electrical control signal is applied to the mechanical circuit breaker. After operation of the mechanical circuit breaker, the ASB is mechanically disconnected from the body of the AO and all operations are as described above.

Measurement of the current distance between ASB and PSO (PO), which has surfaced on the sea surface, is carried out using a navigation radar station and in the unit for technical measurement of the current distance using a distance strobe shaper.

After the ASB and the cable are lifted aboard the PSO (or software), depending on the current situation, the following occurs:

- the choice of the anchor chain of ZO (especially with large and medium displacement);

- descent to the AE along the ASB cable of a mechanical hook with a powerful PSO cable;

- smooth separation of the AU from the ground with the help of an ASB cable, a selected AO anchor chain, a more powerful JI cable and further towing (towards shallow water, towards the JI, etc.) at a safe JI speed (PO);

- ZO rise to the surface of the sea or to the side of the SSO.

At the same time, the salvation of people who find themselves in the AO begins already at the stage of raising the AO to the surface of the sea. In this case, the following activities can be performed:

- people in the air cushion of the ZO come up on their own or with the help of divers PSO (PO);

- after fixing the AU at the side of the PSO (PO) or on board the PSO (as well as when the AO is in shallow water), a hole is drilled in the AO housing at the location of people, etc.

There is a method of searching for a sunken object (AO), which consists in its visual detection at the bottom of the sea, comparing it with a reference image and deciding on the detection of a sunken object [1].

The disadvantages of this method include:

1. Limited (units of meters) range.

2. Difficulty in identifying the AO.

3. The impossibility of the operational designation of the location of the AO on the sea surface.

4. The impossibility of operational preparation and lifting of the AO to the surface of the sea or towing in shallow water.

5. The inability to obtain information about the presence of people in the AOR.

6. The inability to control the state of people in the process of rescue operations.

7. The impossibility of saving people who find themselves in the AOR.

There is a method of detecting AO by its secondary acoustic field, which consists in generating and emitting in the direction of AO a pulse signal of the ultrasonic frequency range, locating AO, receiving a reflected signal (echo signal), comparing it with a reference signal and deciding on the detection of AO [2] .

The disadvantages of this method include:

1. Limited (hundreds of meters) range.

2. Limited angular observation sector.

3. The low reliability of the classification of DA.

4. The impossibility of operational designation of the location of AO on the sea surface.

5. The impossibility of the operational preparation and lifting of the AO to the surface of the sea or towing in shallow water.

6. The inability to obtain information about the presence of people in the AOR.

7. The inability to control the condition of people in the process of rescue operations.

8. The impossibility of saving people who find themselves in the AOR.

Closest to the technical nature of the claimed method relates to the method selected as the prototype method, which consists in generating, amplifying and emitting highly directionally in the vertical plane and slightly directionally in the horizontal plane from the search and rescue object (SAR) of a sonar encoded signal that is received, amplified and they are decrypted at the AE, after which an emergency rescue buoy (ASB) is mechanically disconnected directly from it and floats to the surface of the sea, with the necessary preliminary A properly unfastened cable supply is pre-arranged in a container or on the ASB case and is fastened on one side to the AO case, and on the other hand, to the ASB case, on the PSO visually, as well as using a navigation radar and direction finder, a surfaced ASB is searched on the sea surface, as well as technical measurement of the distance between the surfaced ASB and the USAR, after lifting the ASB and the cable aboard the USO, the AU is lifted to the sea surface or towed in shallow water using a cable [3].

The disadvantages of this method include:

1. Limited search performance, since the search is carried out using a JI, the speed of which does not exceed 30-35 km / h.

2. The inability to obtain information about the presence of people in the AOR.

3. The impossibility of monitoring the condition of people in public health during rescue operations.

4. Low efficiency, due to the long search time, the rescue of people caught in the AO.

5. Limited scope.

The problem that is solved by the invention is to develop a method that is free from the above disadvantages.

The technical result of the proposed method consists in a significant increase in the search performance, the possibility of obtaining information about the presence of living people in the AO, monitoring their condition during the rescue operations and the high efficiency of saving people who find themselves in the AO.

This goal is achieved by the fact that in the known method of searching for and raising to the surface of the sea AE, as well as rescuing people caught in it, which consists in generating, amplifying and emitting a hydroacoustic encoded signal from a PSO, receiving, amplifying and decrypting a hydroacoustic encoded signal in AO, mechanical disconnection of ASB, ASB ascent to the surface of the sea, while the necessary previously unfastened supply of the cable is pre-located in the container or around the ASB body and is fixed on one side to the body of the AO, and the other side to the ASB case, on the SSD, visually, as well as using the navigation radar and the direction finder, the ASB and the ASB that are surfaced are searched on the sea surface, and the distance between the ASB and the SSO pop-up is measured, and after the ASB and the cable are lifted to the PSO, the AE to the sea surface or towing it in shallow water with a cable, the radiation of the hydro-acoustic encoded signal is carried out non-directionally, additionally use search objects (PO) - you high-speed surface, underwater and aircraft, spacecraft, as well as people themselves caught in the sunken object, additionally use control signals for the ASB as impact signals from the inside of the body of the sunken object; on the ASB buoy that floats to the sea surface, they additionally listen to sounds coming from the AU, additionally used underwater are aircraft and aircraft, as well as land vehicles.

A significant (by an order of magnitude or more) increase in search performance is achieved due to the fact that the search for AO is carried out not only with the help of SAR, but also with the help of software - high-speed surface, submarine and aircraft, spacecraft, as well as with the help of the people themselves who find themselves in DA.

The ability to obtain information about the presence of living people in the AE is achieved due to the fact that on the ASB located in the AE, additionally, shock signals from the AO body from the inside are used as control signals.

The ability to monitor the status of people in the AU during the rescue process is achieved by listening to sounds coming from the AO.

The high efficiency of rescuing people who find themselves in the AO is achieved due to a significant (by an order of magnitude or more) reduction in the search time for AOs - due to the additional attraction of software, as well as due to a more rapid ascent of the AO to the sea surface or its towing in shallow water.

The expansion of the scope is achieved due to the fact that as AO additionally used underwater and aircraft, as well as land vehicles.

Distinctive features of the prototype of the features of the proposed method are:

1. Radiation of the hydroacoustic encoded signal is non-directional.

2. Additionally use the software, as well as the people themselves who find themselves in the public domain.

3. Additionally, submarines are used as the USAR forces.

4. Additionally, as signals for ASB surfacing, use is made of strikes from the inside of the body of the AO.

5. Additionally, on the ASB that has surfaced on the sea surface, they continuously listen to sounds coming from the AO, and also continuously record them.

6. Additionally, submarine and aircraft, as well as land vehicles, are used as AO.

The presence of distinctive features from the prototype features allows us to conclude that the proposed method meets the criterion of "novelty."

An analysis of the known technical solutions in order to detect the indicated distinctive features in them showed the following.

Sign 1 is well known in sonar.

Sign 3 and 6 is known during rescue operations.

Signs 2, 4, and 5 are new and it is not known how to use them to search for AOs, as well as save people who find themselves in it. At the same time, signs 2 and 5 are used during rescue operations.

Thus, the presence of new significant features, together with the known ones, provides the appearance of the proposed solution with a new property that does not coincide with the properties of the known technical solutions - to quickly detect, identify and determine the location on a large area of the AO, quickly prepare and raise to the sea surface a AO or tow it in shallow water, and also in the shortest possible time to save the lives of people who find themselves in the AOR.

In this case, we have a new set of features and their new relationship, moreover, it’s not a simple combination of new features and already known ones, but the execution of operations in the proposed sequence leads to a qualitatively new effect.

This circumstance allows us to conclude that the developed method meets the criterion of "significant differences".

Figure 5 illustrates the appearance of the blocks of formation, amplification and radiation of a hydroacoustic encoded signal and ASB for shallow (depth not more than 100 m) areas.

The device contains: PSO (1), software (2) and ZO (3).

On PSO (1) without fail there are: blocks of formation (4), amplification (5) and radiation (6) of the hydroacoustic encoded signal F _cs , navigation radar station (7), direction finder (8) of radar signals ω, technical measurement unit for current distances (9), as well as a device for towing a vessel (10) and a device (11) for lifting AE to the sea surface.

On the software (2), the navigation radar station (7) is mandatory, and optionally there are: the direction finder (8) of the radar signals ω, the units for generating (4), amplification (5) and radiation (6) of the hydro-acoustic encoded signal F _кс , a unit for technical measurement of the current distance (9), as well as a device (10) for towing a vessel.

On the AO (3) there is an ASB (12) having a waterproof case (13), the necessary supply of a cable (14), which is placed depending on the particular AO (3) either around the ASB case (13) (12), or in a special container (15) attached to the outside of the AO (3).

Inside the housing (13) of the ASB (12) there are: receiving units (16), amplification (17) and decryption (18) of the hydroacoustic encoded signal F _x , decryption (19) of shock signals from inside the AO (3), a mechanical disconnector (20), a digital information storage device (21), a radio transmitter (22) and a high-capacity power supply unit (23), charged once a year and providing power to signal amplification units (17), signal decryption (18) and (19), a mechanical disconnector (20), digital an information storage device (21) and a radio transmitter (22), as well as a flashing beacon (29) located on the ASB housing (13) (12). On the housing (13) of the ASB (12) are also located: a radar antenna (24) located in the transport version (folded), a hydrostat (25), a reflector (26), a reflector of radar signals (27), a raised beam (28) and a flashing beacon (29).

The method is implemented as follows (figure 1 - figure 4).

At each moving AO (3), which can be used as air (aircraft, helicopters, etc.), surface (ships, hovercraft, etc.) and submarines (tourist and military submarines, inhabited submarines, etc. ) ships, as well as land vehicles (for example, cars driving onto the ice of the sea, lakes, etc.), there is one place in the most optimal (for design considerations of the AU, implementation of the method in this area, etc.) or several (depending on the importance of the AO, its size and .d.) CRS (12). Each ASB has a waterproof housing (13), which prevents flooding of the ASB or its mechanical damage at all depths of the intended area of use. For coastal areas, for example, the ASB case can be made of fiberglass, and for oceanic areas - of titanium, etc. In this case, the required supply of the cable (14), with positive or zero buoyancy, depending on the type of AO (3), is placed either around the ASB body (13) (12) or in a special container (15) attached to the outside of the AO (3) ) In any case, free (excluding tangling, etc.) unwinding of the cable should be ensured when the ASB ascends to the sea surface.

Inside the housing (13) of the ASB (12) there are: receiving units (16), amplification (17) and decoding (18) of the hydroacoustic encoded signal F _x , a decoding unit (19) of shock signals from inside the AO, which is connected to the output of the amplification unit (17 ) parallel to the decryption unit (18), as well as a mechanical disconnector (20) that provides the required effort (shock loads from waves, wind, etc.) of the cable after the ASB (12) ascends to the sea surface, a digital information storage device (21), providing continuous registration of all signals arriving through the receiving units (16) and Lenia (17) of the tripping hydrostat (25) CRS (12) to the closure rescue radio transmitter (22) and vysokoemkostnoy power supply (23) chargeable once a year. On the housing (13) of the ASB (12) are located: a radar antenna (24) located in the transport version (folded), a hydrostat (25), a reflector (26), a reflector of radar signals (27), a raised beam (28) and a flashing beacon ( 29).

After the occurrence of force majeure circumstances (aircraft crash, sinking of a surface vessel, etc.) and the complete immersion of the AU under water (after which its further turning over, etc., is excluded), the hydrostat is triggered for the first time, because the external pressure exceeded atmospheric by several fractions of atm (for example, 0.5 atm - 5 m depth, etc.) and the electric power supply of the corresponding ASB units is turned on. At the same time, all signals coming through the receiving (16) and gain (17) blocks begin to be continuously recorded on the digital information storage device (21).

Living people who find themselves in different places of the AO begin to give SOS alarms by tapping metal objects on the AO case (3) from the inside.

After the acceptance of control alarms F _sos for ASB ascent (alternating pauses and series of metal shocks from inside the AO about its body, etc.), which are predefined in special places at the AO (for example, in places where people are likely to be at the time of sleep, shift, etc. .d.), its amplification and decryption (comparison with a predetermined standard), an electrical control signal is supplied to the mechanical breaker (20).

After operation of the mechanical circuit breaker (20), the ASB (12) is mechanically disconnected from the body of the AO (3). Due to its buoyancy and the necessary supply of the cable (14), previously placed either around the ASB (13) hull (12) or in a special container (15), the ASB (12) begins to float to the sea surface.

A hydrostat is triggered a second time on the surface of the sea (the external pressure has become atmospheric). At the same time, on the housing (13) of the ASB (12), the radar antenna (24) is mechanically straightened, which is in the transport version up to this point in time, and the signals ω begin to be transmitted to the radio air in the pulsed (pulse duration is a fraction of a second) mode and for a short time (for example , 1 time in 4 hours for 10 seconds, etc.) signals coming from the AU (3): metal strikes against the AO case from the inside, etc. In addition, the raised beam (28) is triggered and the flashing beacon (29) starts to work , and the reflector of radar signals (27), is placed th on the housing (13) CRS (12), provides effective reflection of radar signals from a radar navigation (7).

Signals at the frequency ω _i (for example, i = 1 - for the passenger ship "Europe", i = 2 - for the airborne "1313", i = 3 - for the fishing seiner "Bor", etc.) begin to receive the direction finders of the nearest PSO (1) and software (2).

The information received from the direction finders (8) of the PSO (1) and all software (2), as well as data from other sources (dispatcher, random witnesses, etc.) are immediately transmitted to the coastal center. To search for DZ (3) in a given (supposed) area, at the nearest JI (1) and PO (2) navigation radars (7) are used, on JI (1) and on the part of PO (2), additionally, formation units (4 ), amplification (5) and radiation (6) of the hydroacoustic encoded signal F _cc , as well as a unit for measuring the current distance (9). The visual observation is intensified, and a device for towing a ship (10) and a device (11) for lifting AE to the sea surface are being prepared for use (warming up, etc.).

In a given area, discretely, every 30-50 km (range in a given area of the encoded signal F _ks ), with PSO (1) and part of the software (2) at the ship's stop (in the helicopter “freeze” mode, etc.) block (6) is lowered into the water to a depth of 10-15 m along the cable.

In the forming unit (4), a code is set corresponding to the ASB number (12) of the AO (3). In the amplification unit (5), the code signal F _{cc is} amplified to the required level, and using the block (6), the hydroacoustic coded signal F _{cc is} emitted non-directionally (including towards the CZ).

Using the reception unit (16) located inside the ASB housing (13) (12), a hydroacoustic encoded signal F _cc is received, which is then amplified to the required level in the amplification unit (17) and compared with the code signal in the decryption unit (18) hydro-acoustic encoded signal F _x . If the code matches, an electrical control signal is supplied to the mechanical circuit breaker (20).

After operation of the mechanical circuit breaker (20), the ASB (12) is mechanically disconnected from the body of the AO (3). Due to its buoyancy and the necessary supply of the cable (14), previously placed either around the ASB (13) hull (12) or in a special container (15), the ASB (12) begins to float to the sea surface.

A hydrostat is triggered a second time on the surface of the sea (the external pressure has become atmospheric). At the same time, on the housing (13) of the ASB (12), the radar antenna (24) is mechanically straightened, which is in the transport version up to this point in time, and the signals ω begin to be transmitted to the radio air in the pulsed (pulse duration is a fraction of a second) mode and for a short time (for example , 1 time in 4 hours for 10 seconds, etc.) signals coming from the AU (3): metal strikes against the AO case from the inside, etc. In addition, the raised beam (28) is triggered and the flashing beacon (29) starts to work , and the reflector of radar signals (27), is placed th on the housing (13) CRS (12), provides effective reflection of radar signals from a radar navigation (7).

The measurement of the current distance is carried out in the unit for the technical measurement of the current distance (9) using a distance strobe shaper (Fig. 4). At its first (triggering) input, a request signal F _cc is received. The response signal ω ASB (12), having a delay for the propagation time of the hydroacoustic encoded signal F _ks , emitted using a radio transmitting antenna (24) and received by the direction finder (8) of the FSO (1), or (and) the software (2), as well as the transmitted through the response signal processing unit of the technical distance measuring unit (9), it is fed to the second (stopping) input of the distance gate shaper. Thus, a pulse (strobe) is formed with a duration proportional to the current distance from the block (6) of non-directional radiation of the hydroacoustic encoded signal F _cc to the ASB radio transmitting antenna (24) (12).

After the ASB (12) and the cable (14) are lifted aboard the SSF (or PO), depending on the current situation (determined by the remoteness of the disaster site from the shore, the composition of forces and rescue equipment and other conditions):

- the choice of the anchor chain of ZO (especially with large and medium displacement);

- descent to the glacier (especially with a large and medium displacement) along the cable (14) of a mechanical hook with a more powerful PSO cable;

- smooth separation of the AO (3) from the ground using a cable (14), or a selected AO anchor chain, or using a more powerful JI cable and further towing (towards the nearest shallow water, islands, coasts, towards the JI, etc. ) at the most safe speed of PSO (ON);

- the rise of the AO to the surface of the sea or to the side of the SSO (1).

At the same time, the salvation of people who find themselves in the AO begins already at the stage of raising the AO to the surface of the sea. In this case, the following activities can be performed:

- people in the air cushion of the ZO come up on their own or with the help of divers PSO (PO);

- after fixing the AU at the side of the PSO (PO) or on board the PSO (as well as when the AO is in shallow water), a hole is drilled in the AO housing at the location of people, etc.

Thus, the advantage of the developed method is as follows.

A significant (by an order of magnitude or more) increase in search performance was achieved due to the fact that the search for AOs is carried out not only with the help of the SAR, but also with the help of software - high-speed surface, submarine and aircraft, spacecraft, as well as with the help of the people themselves who find themselves in DA.

The possibility of obtaining information about the presence of living people in the AE is achieved due to the fact that on the ASB located in the AE, additionally, as control signals, they use blows to the AO body from the inside.

The ability to monitor the condition of people in the AE during the rescue process was achieved by listening to sounds coming from the AO.

The high efficiency of rescuing people who ended up in the AO was achieved due to a significant (by an order of magnitude or more) reduction in the search time for AOs - due to the additional attraction of software, as well as due to a more expeditious ascent of the AO to the sea surface or its towing in shallow water.

The expansion of the scope was achieved due to the fact that underwater vehicles and aircraft, as well as land vehicles, are additionally used as SCs.

Marine tests of the method were carried out in 2004 and 2005 in the Avacha Bay of the Kamchatka Peninsula with sea waves up to 3 ... 4 points and a water temperature of +5 to +18 degrees Celsius. The following main results were obtained:

- the range was within 15 ... 30 km;

- the accuracy of determining the distance between PSO (PO) and ASB was 10 ... 20 m (1-2 vessel hull lengths) at a distance of 7 ... 10 km;

- the average time to search for ASB on the sea surface using a ship's radar station at a distance of 7 ... 10 km did not exceed 1 min.

Figure 5 illustrates the appearance of the units used in the testing process of the formation, amplification and radiation of the hydroacoustic encoded signal and ASB.
