Description

The claimed invention relates to safety systems when using small arms and hunting weapons in the conditions of joint actions of shooters in a group.

With the joint actions of shooters in a group, in some cases the problem arises of preventing an accidental defeat of a false target (defeat of one's own), especially in conditions of poor visibility. This problem is similar to the recognition of “friend or foe” during combat operations.

A known method of identifying "friend or foe" in relation to technology, presented in the patent [1] - RU 2353892 C2, F41H 13/00, G01S 17/74, 04/27/2009, in which the belonging of the object of technology to "own" is determined by the IR spectrum -radiation, modified in a certain way by applying to the radiating surface a special coating containing certain components that change the spectrum of infrared radiation.

Known systems of recognition of "friend or foe", used to recognize equipment belonging to "friend", based on radar methods. For example, in the patents [2] - RU 2100823 C1, G01S 13/78, 12/27/1997; [3] - RU 2324137 C1, F41H 7/02, F41H 13/00, 04/27/2009, recognition systems are described, the operation of which is based on the formation of a light response when the requested object is irradiated with a laser beam modulated by a specific code that is recognizable only on its own object. In the article [4] - I. Politov. Identification systems "friend or foe" MBT "ABRAMS" and BMP "Bradley" // Foreign Military Review, 2001, No. 7, pp. 24-26, an identification system based on sending a transmitting antenna with a needle-shaped beam pattern of the encoded request radio signal in side of the requested object and receiving a response from it received by the omnidirectional antenna.

The considered systems can be connected with weapon control units, prohibiting its use in relation to “their” objects of equipment. The main disadvantage of these systems is that they are applicable only in conditions of direct visibility between the object performing the request and the requested object and their effectiveness depends on the conditions of visibility (radio visibility) on the “interrogator-responder” line. In addition, for the system presented in [1], an important factor is the cleanliness of the coated emitting surface.

Known recognition system "friend or foe", presented in the patent [5] - RU 2386144 C1, G01S 13/78, 04/10/2010, using means of individual navigation. In this system, all objects are combined into a local information and control network, which allows each of the objects to transmit and receive information on the coordinates of the strike, to compare the coordinates of the strike with the coordinates of its own location, and to broadcast an alarm that prohibits this strike if it is in danger zone. The system is applicable when shooting at specified coordinates, as well as when using high-precision weapons with guidance on coordinates. The system is not applicable in the conditions of use of conventional weapons induced by the shooter.

The task of ensuring security when using small arms in certain situations is solved by using the device presented in the patent [6] - RU 2328693 C2, F41H 1/00, 07/10/2008, adopted as a prototype.

The prototype device is designed to prevent the defeat of small arms of its military personnel on the battlefield by signaling that the aiming line is in the prohibited sector, where it is possible to defeat "your" partner (military serviceman), who is part of a group for joint actions.

The prototype device contains the first equipment placed on a weapon equipped with a laser target designator, and the second equipment placed on the outfit. The first equipment includes a coding unit for laser target designator radiation, a photodetecting and decoding unit coupled to it, and a signaling unit. The second equipment includes a transponder, which includes a carrier base with optical fibers, the input ends of which are distributed over the surface of the uniform, and the output ends are combined and, using an auxiliary lens and a color separator, are coupled to a transponder photodetector that receives and encodes a signal at the wavelength of the laser pointer decoding and recognition. The transponder’s photodetector is connected to a transponder laser emitting an encoded signal at a wavelength different from the wavelength of the laser target, perceived by the photodetector unit coupled to the laser target.

The prototype device operates as follows. A laser pointer emits an encoded signal. In the case of pointing the target to "their", the coded laser signal of the target reaches the input ends of the optical fibers distributed over the surface of the uniform. The received signal is transmitted through the optical fiber to the photodetector of the defendant, where it is decoded and recognized. After recognition, the received signal is transmitted to the laser transponder, which under the influence of this signal generates an encoded output signal at a wavelength different from the wavelength of the laser target. This signal is emitted towards the laser pointer and, passing through the output lens of the pointer, it enters the photodetector and decoding unit, and then to the input of the alarm unit, providing a warning to the shooter about pointing the weapon at “his own”, that is, about the sighting line getting into the prohibited sector .

Obviously, the solution to the problem of ensuring security when using small arms is achieved by the prototype device in a limited number of cases, namely, when there is a hit of the laser beam of the responder in the target designator lens, thus leaving a significant number of real-life situations without solving the security problem .

The technical result, to which the claimed invention is directed, is to create a more effective signaling device warning a shooter about a hit of an aiming line in a prohibited sector, where it is possible to defeat "one's own" partner (serviceman), who is part of a group for joint actions.

The essence of the claimed invention is as follows. A signaling device for a shooter warning about the hit of an aiming line in a forbidden sector, contains equipment located on the uniform of the shooter, and equipment placed on the weapon, including an alarm unit. Unlike the prototype, the equipment placed on the weapon additionally contains a group of sensors for the spatial orientation of the barrel of the weapon and an interface transceiver unit whose inputs are connected to the outputs of these sensors and the output is connected to the input of the signaling unit. The equipment located on the gunner's outfit contains an interface transceiver unit connected by a local data transmission / reception channel with an interface transceiver-unit located on the weapon, as well as an aiming line vector measurement unit, the input of which is connected to the output of the interface transceiver block located on the gunner's outfit, a navigation unit designed to determine the coordinates of the shooter's location, a transceiver designed to broadcast encoded information information about the coordinates of the shooter and receiving from the air encoded information about the coordinates of objects towards which shooting is prohibited, whose input through the coding block is connected to the output of the navigation block, a unit for calculating ranges and direction vectors to objects towards which shooting is prohibited, the first input of which is connected with the output of the navigation unit, and the second input through the decoding unit is connected to the output of the transceiver, the unit comparing the estimated ranges with the range of destruction of small arms, forming the first a control signal for the signaling unit, the input of which is connected to the first output of the unit for calculating ranges and direction vectors to objects towards which shooting is prohibited, and the output is connected to the first input of the interface transceiver unit located on the uniform of the shooter, and the unit for comparing the vectors of calculated directions and vector aiming lines, forming a second control signal for the signaling unit, the first input of which is connected to the second output of the unit for calculating ranges and direction vectors to objects, in Oron which shooting is prohibited, a second input connected to the output measuring unit sighting vector line, and an output connected to the second input interface transceiver unit housed on uniform arrow.

The invention and the possibility of its implementation are illustrated by the structural diagram of the device.

The inventive device in this example contains equipment 1 placed on the weapon, and equipment 2 located on the uniform of the shooter.

Equipment 1 contains a group of sensors 3 for spatial orientation of the barrel of the weapon, an alarm unit 4, which serves to warn the shooter about the sighting line getting into the prohibited sector, and an interface transceiver unit 5. The inputs of the interface transceiver unit 5 are connected to the outputs of the sensors 3, and the output is connected to the input of the unit 4 alarms. Block 4 alarm is made in such a way that its inclusion is carried out when removing weapons from the fuse.

Equipment 2 comprises an interface transceiver unit 6 connected by a local channel for receiving and transmitting data (for example, Bluetooth) with an interface transceiver unit 5 located on the weapon.

Equipment 2 also contains a block 7 measuring the vector of the aiming line, the input of which is connected to the output of the interface transceiver block 6, a navigation block 8, designed to determine the coordinates of the location of the shooter, a transceiver 9, designed to broadcast encoded information about the coordinates of the shooter and reception from the air of the encoded information about the coordinates of objects towards which shooting is prohibited, coding unit 10, decoding unit 11, unit 12 for calculating ranges and direction vectors for Objects to which shooting is prohibited, block 13 comparing the estimated ranges with the range of destruction of small arms, forming the first control signal for the signaling unit 4, and block 14 comparing the vectors of the calculated directions and the aiming line vector, forming the second control signal for the signaling unit 4.

The input of the transceiver 9 through the encoding unit 10 is connected to the output of the navigation unit 8, which is also connected to the first input of the range and direction vector calculation unit 12 for objects to which shooting is prohibited, the second input of which through the decoding unit 11 is connected to the output of the transceiver 9.

The first output of the unit 12 for calculating ranges and direction vectors for objects toward which shooting is prohibited is connected to the input of the unit 13 for comparing calculated ranges with the range of destruction by small arms, the output of which is connected with the first input of the interface transceiver unit 6.

The second output of the unit 12 for calculating ranges and direction vectors for objects towards which shooting is prohibited is connected with the first input of the unit for comparing the vectors of the calculated directions and the aiming line vector 14, the second input of which is connected with the output of the unit for measuring the aiming line vector 7, and the output is connected with the second input of the interface transceiver unit 6.

The operation of the claimed device is as follows. From the sensors 3 located on the weapon, for example, the azimuth and elevation sensors included in the equipment 1, the data are transmitted to the inputs of the interface transceiver unit 5, which carry information about the spatial orientation of the weapon barrel and, accordingly, the aiming line. This data from the output of the interface transceiver unit 5 through a local channel of data reception and transmission is fed to the input of the interface transceiver unit 6, which is part of the equipment 2, located on the uniform of the shooter, and then fed to the input of the unit 7 for measuring the aiming line vector.

At the same time, using the navigation unit 8, for example, operating on the signals of global navigation satellite systems, the current coordinates of the arrow location are determined.

Data on the coordinates of the location of the arrow is received at the first input of the block 12 for calculating ranges and direction vectors for objects towards which shooting is prohibited, and at the input of the coding block 10.

In the coding unit 10, the data on the coordinates of the location of the shooter together with its identification mark are encoded and then transmitted to the input of the transceiver 9, which transmits them using the omnidirectional transceiver antenna to receive this information by other “own” arrows belonging to the group for joint actions .

The same transceiver 9 receives coded information from the air about the coordinates of objects in the direction of which shooting is prohibited, for example the coordinates of other “their” shooters who are part of a group for joint actions.

Data on the coordinates of objects in the direction of which shooting is prohibited is decoded in the decoding unit 11 and then fed to the second input of the block 12 for calculating ranges and direction vectors for objects in the direction of which shooting is prohibited.

From the first output of block 12, the calculated ranges to objects toward which shooting is prohibited is sent to the input of block 13, where they are compared with a threshold value determined by the range of destruction by small arms. If, as a result of the comparison, it is found that the estimated ranges to objects toward which shooting is prohibited is less than or equal to the range of destruction by small arms, the first control signal for signaling unit 4 is generated at the output of block 13, which is fed to the first input of the interface transceiver block 6.

From the second output of block 12, the calculated data of direction vectors for objects toward which shooting is prohibited is sent to the first input of block 14, where they are compared with the data of the aiming line vector coming to the second input of block 14 from the output of block 7. If, as a result of the comparison, that the vector of the line of sight coincides or is close to one of the direction vectors for objects toward which shooting is prohibited, at the output of block 14, a second control signal is generated for the signaling block 4, which is fed to the second input of the interface transceiver unit 6.

The first and second control signals from the output of the interface transceiver unit 6 through a local channel of data reception and transmission are fed to the input of the interface transceiver unit 5, which is part of the equipment 1 located on the weapon, and then fed to the input of the signaling unit 4.

If the weapon is not removed from the fuse, then the alarm unit 4 is turned off and the presence of the indicated first and second control signals does not trigger it.

If the weapon is removed from the fuse, then the signaling unit 4 is turned on and responds to the presence of the first and second control signals, for example, by lighting one or more LEDs, thereby warning the arrow about pointing the weapon in the direction of “his” partner (serviceman), who is part of the group for joint action.

It is obvious that the claimed device has, in comparison with the prototype, a wider range of possibilities for solving the problem of ensuring security when using small arms, since it eliminates the need for the laser beam of the responder to enter the target designator lens, as is required in the prototype, and does not need to provide direct visibility to the shooter and an object towards which shooting is prohibited.

The above shows that the claimed invention is feasible and ensures the achievement of a technical result, which consists in the creation of a more effective signaling device, warning the shooter about the hit of the aiming line in the prohibited sector, where it is possible to defeat "his" partner (military man), included in the group for joint actions.
