Description

The invention relates to the field of weapons and military equipment, in particular to fire control systems (LMS) of combat vehicles (BM) such as tanks, infantry fighting vehicles, armored personnel carriers, BMDs, etc.

As an analogue, the BM fire control system can be considered (see the description of the RF patent for invention No. 2360208, IPC 7 F41H 7/02, F41A 27/30, published on June 27, 2009 according to application No. 2007124064 of June 26, 2007, the patent holder KBP JSC, Tula), which includes a gunner’s sight, commander’s sight, weapon stabilizer, tele-teplovizovaya object tracking automaton (ASOTT), control unit, gunner’s operator’s and commander’s console, ballistic computer with input information sensor system, automation unit.

Common features of the analogue and the claimed technical solution are the gunner’s sight, the commander’s sight, the weapon stabilizer (in the claimed technical solution it’s the weapon guidance system control unit), the gunner’s operator’s console and the commander’s console, a ballistic computer with an input information sensor system, and an automation unit (in the claimed technical solution - the last two are included in the control unit for automation).

The reason that impedes the achievement of the claimed technical solution is that this system does not allow simultaneous processing of video information in various spectral ranges, ranking targets according to the degree of danger and determining their coordinates, simultaneous automatic tracking of several targets in the sight of the sight, which significantly reduces the detection capabilities of BM . The presence in the LMS of analog and digital subsystems and the consequent need for digital-to-analog and analog-to-digital conversions leads to a decrease in accuracy characteristics and speed. Remote control of weapons is not provided.

As an analogue, the BM fire control system can also be considered (see the description of the RF patent for the invention No. 2553712, IPC 7 F41G 5/24), publ. 06/20/2015 by application No. 2014110448 dated 03/18/2014, patent holder of OJSC SKB PA, Kovrov, containing control panels for GN and HV, the stabilizer control unit, including serial bus signal conditioners, control signal signal calculation unit, ballistic correction calculation unit, as well as power amplifiers, gearboxes and high-voltage motors of launchers and guns, turret position sensors, weapon-mounted position sensors, roll and pitch sensors, gun absolute speed sensors GN and VN, a master device of an inertial stabilization object independently stabilized in space according to GN and VN, equipment of the control system of the fighting compartment, serial data buses.

Common features of the analogue and the claimed technical solution according to claim 1 are a master device of an inertial stabilization object independently stabilized in space (in the claimed technical solution it is part of the gunner’s sight, commander’s sight), control panels for GN and HV, the stabilizer control unit (in the claimed technical solution - control unit for the guidance system of the weapon), power amplifiers, gearboxes and electric motors of the high-voltage launch guns, turret position sensor, high-speed weapon position sensors, sensors to roll and pitch sensors absolute angular velocity of the gun GN and BH.

The reason that impedes the achievement of the claimed technical solution is the insufficient detecting capabilities of the weapons complex, the inability to rationally choose your type of weapons and ammunition, adapted for a specific purpose, as well as to make accurate shooting due to the neglect of meteorological ballistic data due to the lack of appropriate sensors.

The closest analogue of the invention to claim 1 is the fire control system of a combat vehicle (see RF patent for utility model No. 134624, IPC 7 F41G 5/24, published on November 20, 2013 by application 2013130584/28 of July 2, 2013, patent holders Open Joint Stock Ural Design Bureau of Transport Engineering and Open Joint-Stock Company Scientific-Design Bureau of Computing Systems), which contains a multi-channel gunner’s sight, a panoramic commander’s sight, a television backup-sight, a video signal switching unit, a system control unit remote machine gun control, video observation devices of the commander and gunner and commander and gunner panels, sensors taking into account the position of the gun, turret position, roll and pitch sensor, wind sensor, gun barrel bend sensor, speed sensor, multiplex information exchange channel, automatic loading control unit , weapon stabilization control unit, digital video processing unit, loading console, control panel of the fire control system of a combat vehicle and automatic loading machine, equipment with string and input corrections, multiplex channel of information exchange, digital channel of information exchange of type RS 422 and digital channel of information exchange of type CAN.

Common features of an analogue (prototype) and the claimed technical solution are the gunner’s sight and the commander’s sight, the video observation devices of the commander and gunner (in the claimed technical solution are the video modules of the gunner and commander) and the commander and gunner’s panels (in the claimed technical solution are the gunner’s and commander’s remote control ), sensors that take into account the position of the gun, the position of the tower, the roll and pitch sensor, the wind sensor (in the claimed technical solution is included in the atmospheric condition meter), speed sensor B , Weapon stabilization control unit (in the claimed technical solution - guided weapons system control unit), the block of digital image processing (in the claimed technical solution - video processing units).

The reasons that impede the achievement of the claimed technical result are the following: the effective defeat of the entire range of targets intended for BM of the type in question is not ensured, the possibility of using special weapons for each type of target, the inability to remotely control the main weapons, the absence of guided weapons with stabilization independent of the main weapons, insufficiently high reliability of the target detection and tracking system due to the lack of duplication of these processes owls.

The task to which the claimed technical solutions are directed is to increase the accuracy and efficiency of firing at an expanded range of targets, in a wide range of conditions for combat use; expanding the capabilities of the BM, providing remote control of weapons (ensuring the uninhabitability of the fighting compartment), increasing the search and detection capabilities of BM.

In addition, when using the inventive SLA, it is possible to increase reliability, reduce the number and laboriousness of performing tuning operations, as well as unification both in the sense of using armored vehicles on various samples: tanks, infantry fighting vehicles, armored personnel carriers, infantry fighting vehicles, and for use on stationary and sea-based facilities .

The technical result provided by the implementation of the proposed technical solution is achieved due to the fact that:

- digital angular position and angular velocity sensors are used with lower values of the absolute error of the output signal;

- digital processing of video images coming from the technical vision channels of the sighting system is carried out in real time, separately through the channels of the gunner and commander;

- the signals are transmitted directly in digital code, without additional intermediate conversions of values, due to which the additional errors caused by them are eliminated;

- implementation of various functions, including new, achieved by finalizing and adjusting the software of the LMS subsystems, without changing their hardware implementation;

- high-performance computing tools of BOVI allow you to implement an automatic search and tracking system, which significantly (several times) reduces the time and increases the likelihood of target detection compared to the "manual" search;

- simultaneous processing of video information in various spectral ranges, ranking of targets by degree of danger and determination of coordinates, simultaneous automatic tracking of several targets in the field of view of the sight are provided;

- the block-modular principle of the construction of the LMS allows you to quickly modify its configuration and compose the LMS of various options depending on the tasks to be solved and cost constraints;

- the implementation of remote blasting of shells in the air allows you to increase the reduced area of destruction, especially manpower, air targets, including the most popular type of unmanned aerial vehicles, lightly armored vehicles.

START 3 STU provides stabilization and stable guidance of weapons when firing from a place, on the move and afloat with all types of weapons in the BM:

BUA ARM 24 provides information management of the subsystems of the OMS and the interaction of the OMS with the information and control system BM, as well as the distribution of the supply voltage of the onboard network to the AWS equipment, the formation and broadcasting of relay control commands and implements the following functions:

switching of video streams transmitted via Ethernet digital channels from the PN and PC to the video signal receivers: VM-N and VM-K chassis equipment; transmission of video streams from video sources to the chassis on VM-N and VM-K; distribution of supply voltage of the AWP equipment; providing information exchange of BM with BIUS via CAN; formation of BM control commands (analog and CAN channel) in the external control mode; providing information exchange between CAN channels of the OMS; reception and transmission of relay signals coming from AWP equipment to the FCS, providing weapon firing modes.

The functions included in the workstation VM 27, 28, PN-N 31 and PN-K 32 are similar to those used in the analogs and prototype / 1-3 /.

UV-N 29 and UV-K 30 are designed for operational control of BM from the workplace of the gunner and commander.

BUA 19 is structurally made in a metal case, on which the connecting connectors are located, through which power is supplied to it, and data is exchanged with the FCS subsystems and the executive subsystems of the automation system are connected.

The BUA 19 includes (see Fig. 2) a ballistic correction calculation module (MVBP) 33, an automation control module (MUA) 35 and a video module control module (MUVM) 34, as well as a primary current source 36, including a current stabilizer 37 2A for power supply circuit of electric ignition UR, the interface unit 51.

The control unit must provide the following functions: issuing signals to the control unit for controlling BM actuating devices, issuing CAN-4 control signals to the control unit for the cannon, control unit for small caliber control unit, control unit for large caliber control unit, receiving, processing signals from sensors, sights, calculating and the issuance of ballistic corrections taking into account the movement of the target and the carrier, as well as weather conditions, ammunition storage conditions, the location of the target and carrier, the management of the LMS functioning modes: the current type of ballistics, the selected drive, commands to stabilized platforms about the selected source of the guidance signal, target designation from the chassis, storage of information, for example, about the shooting of weapons, numbers of units, devices, units that do not have their own microcontroller, and the issuance of this information upon request, etc.

MVBP 33 is physically a digital ballistic computer board and allows you to quickly enter an almost unlimited number of ballistics. To do this, it has several backup addresses with a volume (number of bits) corresponding to the necessary amount of information support (a set of coefficients) for the ballistics of newly developed ammunition.

To ensure the possibility of prompt input of new ballistics, information software is supplemented, for which a set of approximating coefficients for the newly introduced ammunition is calculated using the new firing tables, the main and correction ones.

To display information about the newly developed ammunition on the video module (VM), the software for the video module control module VM (MUM) is adjusted (supplemented).

BOVI-N 4 and BOVI-K 5, which have high-performance computing tools, provide an increase in the quality and informativeness of the image of the phono-target environment on VM screens, auto tracking of targets and the mode of automatic search and recognition of targets with their ranking according to the degree of danger. An analogue of BOVI can be a multichannel television machine for the Pantsir anti-aircraft missile-cannon complex.

BZK 27 provides +27 voltage supply to the BM equipment blocks and protects the network from overloads and short circuits, controls the electromagnetic couplings of the HV drive of the weapon and GN unit, controls the stoppers of the weapon and BM block in the same way, gives signals to the ACU in case of any failure or part of the BZK. Functional analogue of the BZK 27 is the communication box of the B8Y01 “Bahcha-U” combat modules (B05Y01 “Berezhok”).

VKU 28 provides the transmission of electric current and electrical signals, optical, information and video signals from the chassis to the rotating fighting compartment.

KDU VPS 23 implements remote control of the time of undermining a projectile with a multifunctional fuse on the trajectory, and also provides the exchange of information with the MSA BM. The Russian Forsyth type for 30 mm ammunition and foreign Aynet type in 40 mm Bofors guns, as well as those deployed on 30 mm ammunition in the Puma infantry fighting vehicle, can serve as an analogue.

Information interaction in the LMS is carried out through digital channels. The CAN 2.0 protocol was selected as the main protocol of information interaction in accordance with ISO 11898. When organizing information interaction, the need was determined to use several independent CAN 2.0 channels with different data rates.

The CAN-1 channel implements the exchange of information between the strategic offensive arms control system and the PN and PC stabilization systems (control of the SNA operation modes, transmission of the values of the angles of the sight line of sight and tracking angles for the SNA).

CAN-2 channel implements the transmission of control commands and data (status polls), signs of the operating modes of the LMS components, information from sensors of external conditions and initial data for calculating ballistic corrections, diagnostic information.

The CAN-3 channel provides the transmission of proportional guidance commands for guiding the line of sight from various sources (BOVI-N, BOVI-K, BU ARM, PN-R, PN-K, VM-N, VM-K). CAN-3 is also included in the guidance loop feedback in auto tracking mode.

The CAN-4 channel is used to transmit control commands and data (status polls) between the blocks of electrical equipment: BUA, BU guns, BU PU small-caliber, BU large-caliber PU.

The CAN-5 channel provides the interaction of the ACU with VM-N, VM-K.

To transmit digital video signal from TV and TPV channels PN and PC to the BOVI and AWS, fiber-optic communication lines are used, which allows you to transfer large amounts of video data through the BMI BM.

The principle of the operation of the LMS consists in the principle of “mark on target” traditionally used in LMS of a similar type of BM, in which aiming the weapon at the target consists in tracking the target with a line of sight (the center of the aim mark on the BM screen), realized by the gunner’s sight (commander) in manual or BOVI in automatic mode, and continuous monitoring of the line of sight of the gun barrels, taking into account the calculated angular corrections.

The line of sight of the sight has an independent two-plane gyroscopic stabilization, and its guidance through the channels of vertical and horizontal guidance is carried out from PN-N and PN-K, or BOVI in auto tracking mode according to commands proportional to the required guidance speed. The operating modes of the OMS as a whole and its individual components are set by a set of control commands coming from the AWP equipment and formed by the ACU.

The functioning of the armament complex is ensured by the joint work of the LMS and the electroautomatics equipment, consisting of: BUA, BU guns, BU PU small-caliber, two large-sized PU launchers, BZK, as well as KPU VPS equipment (installation of an uncontrolled fuse fuse.

The interaction of the AWS equipment located in the chassis and the LMS subsystems located in the rotating part of the BM is carried out by means of electrical and optical circuits broadcast through the VKU.

Analog video signals from the TV and TPV outputs of the PN and PC channels, transmitted through the BM VKU directly to the VM, provide duplicate modes of operation of the FCS.

In contrast to the previously created weapon systems of lightly armored vehicles such as “Bakhcha” and “Berezhok,” the BO control equipment, which is part of the ARM-N and ARM-K, is unified and allows you to completely duplicate the work of both sights from any workplace. The priority of management is determined by the crew.

In the “Primary” mode, the armament from which the firing is being carried out, monitors with the help of electromechanical drives the position of the stabilized line of sight for the PN, which the gunner guides with the help of the PN-N, and commands to measure range, fire, switch ammunition types are issued to the OMS, and also management of PN functions. The gunner can use a target tracking machine implemented by BOVI.

The commander in the “Main” mode, using PN-K, searches for targets in manual, semi-automatic and automatic modes, measures the range to the target, and commands to measure the range through the PC are issued to the FCS, the stabilized line of sight of the PC is guided, and the gunner gives target designation with the possibility of transmitting the target captured by the automatic tracking machine, it controls the PN functions (changing the fields of view, performing settings and adjusting TV and TPV images (brightness, contrast, focusing).

In the “Main” mode, the BVBP, which is part of the ACU, calculates and processes corrections of vertical and horizontal lead in view of the following parameters: type of ammunition, current range to target, air temperature, charge temperature, atmospheric pressure, lateral and longitudinal wind component, angular velocity line of sight, roll angle of the machine, elevation angle of the target.

Relevant information comes from the sensors of external conditions 25, 26, the roll and pitch sensors 7, the internal position sensors received via digital CAN communication channels. The angular velocity of the target is determined using the values of the guidance commands received via a digital channel at the input of the PN.

In the “Basic” mode, the following sub-modes can be distinguished: “Range measurement”, “Ammunition type setting”, “Changing the field of view”, “Offsets compensation”, “Automatic target search”, “Working with“ ACS ”,“ Working with OLO ” , “Hunter-shooter”, “Tsu”, “Tracking”, “External target designation”, as well as sub-modes of firing from a gun and machine gun, firing of small and large-caliber SD.

The operation modes of the LMS (change of the LMS operating modes) are carried out with the UV-N (UV-K) activation of the corresponding buttons. At the same time, control commands are issued to the channel of information and logical interaction CAN-2, which ensures switching of the operating modes of the LMS without delays and interruptions in operation.

Thus, the BM fire control system claimed as an invention allows:

- to improve the accuracy and speed of the armament complex through the use of digital sensors of angular position and angular velocities with lower values of the absolute error of the output signal, due to digital processing of video images coming from the technical vision channels of the aiming complex, in real time, separately through the gunner’s channels and commander; direct transmission of signals in a digital code, without additional intermediate conversions, which eliminates additional errors;

- increase firepower, ensuring effective defeat in a wide range of conditions of combat use of the entire range of targets intended for BM of the type in question, by using, in addition to the gun, two types of guided weapons, it becomes possible to choose specialized weapons for each type of target, while the launchers of UR work in independent stabilization mode, similar to the main weapons;

- to increase the search and detection capabilities of BM several times through the use of high-performance computing tools BOVI, separately the operator and the commander, allowing to implement an automatic search and tracking system, which significantly, several times reduces the time and increases the likelihood of target detection compared with manual search modes; by providing simultaneous processing of video information in various spectral ranges, ranking targets according to the degree of danger and determining coordinates, simultaneous automatic tracking of several targets in the field of view of the sight;

- increase the likelihood of hitting targets such as tank-dangerous manpower located both openly and in fortifications (shelters), creating the prerequisites for a more effective fight against air targets, especially easily vulnerable types of UAVs, increasing the likelihood of hitting lightly armored targets by providing air blasting of fragmentation HE shells;

- provide remote control of weapons (uninhabited fighting compartment) through the use of modern effective channels of technical vision;

- expand the functionality of BM, including due to the block-modular principle of constructing the LMS, which allows you to quickly modify the configuration and compose the LMS of various options depending on the tasks being solved by the BM and cost restrictions; implementation of various functions, including new, achieved by finalizing and adjusting the software of the LMS subsystems without changing their hardware implementation;

- to increase the operational characteristics of the control system and the possibility of its diagnosis and adaptation to other weapons control systems due to the availability of information exchange channels between the equipment of the control system of the fighting compartment.

The proposed system is unified and can be used in full or in truncated form as part of various types of armored vehicles: tanks, infantry fighting vehicles, armored personnel carriers, as well as for stationary or sea-based facilities.

Thus, the technical tasks set in the application have been achieved.

The technical advantages given in the description of the system implemented according to the claimed structural scheme are confirmed by tests of prototypes at the testing base of KBP JSC and external bases.
