Description

The invention relates to aircraft equipment, more specifically to equipment designed to ensure the combat use of aircraft (LA) weapons: combat aircraft of front-line, long-range and military transport aviation, combat helicopters. It can be used by enterprises in the aviation and defense industries that are developing "weapons control systems" (WMS) and systems for transmitting / receiving voice information and data.

A well-known fighter weapons control system is designed to ensure the effective destruction of air and ground targets due to the accurate entry into the attack area of a group of fighters, mutual exchange of information, centralized data collection of the air and ground situation, data processing and subsequent solution of target distribution (target designation) tasks on the commander's aircraft general order of battle [RF Patent No. 2024818, published 12/15/1994].

The composition of a modern aircraft weapon control system, regardless of the operational-tactical or strategic purpose of the aircraft; the degree of functional integration of its on-board radio-electronic equipment (avionics), depending on the level of development of the microelectronic base; methods of connecting the whole variety of radio-electronic equipment on board the aircraft (namely, directly with each other via local communication lines or connecting each equipment to the common trunk data bus (MShD) of the aircraft, the exchange of information, which is provided by control commands of the computer complex of the aircraft through a software controller built into a single or distributed field of aircraft cockpit controls and indications) includes:

- airborne radar station (BRLS), for detecting air and ground targets at distances within the radio visibility of the station;

- an on-board optical-electronic, in particular, a television sighting system, designed to detect an air target within optical visibility (after a preliminary exit to the area of \u200b\u200bit location using the above equipment) and to ensure its automatic and semi-automatic tracking based on measuring its coordinates and motion parameters with the help of meters that are part of the sighting systems;

- an on-board set of navigation equipment with flight information sensors, designed for use in aiming, as well as for navigation, for example, after the completion of the attack of the target, with the task to return to the airfield and land;

- a real-time computing (information-analytical) system containing several digital computers (DC) and analog computers designed to process information received from the indicated sensors and meters, and commands from the system control panels to solve the aiming problem, to solve the navigation problem and other computational actions related to the preparation, use of weapons of destruction and control of the results of this use, including in training flights;

- an on-board set of indicators designed to demonstrate to the pilot the necessary information based on the results of the operation of the named sighting systems, guidance and navigation equipment, as well as to present the results of the computer system, implemented through appropriate piloting, in particular, the results of solving the aiming problem;

- an on-board set of equipment for radio telemetry (telephone and telecode) communication for information support of a combat aircraft by receiving voice information and data from the command post of a ground (air) automated control (guidance) system and for communication with aircraft equipped with similar equipment when they interact in a group (groups) with registration and storage of information;

- an on-board set of guidance equipment, telemetrically connected to the equipment of control systems (guidance) similar in purpose.

Information-logical interfacing and circuit combination of the mentioned on-board measuring and actuating devices form a multi-mode technical system that functionally solves one problem: the effective use of combat aircraft weapons, which determines the current name of such a system.

For all subsequent releases of domestic and foreign aircraft for combat use, the above-mentioned composition of the SUV aircraft is typical, defining together with the “crew” the “on-board intelligence” of the aircraft.

This aircraft weapon control system in the proposed technical solution is adopted as an analogue [RF Patent No. 2439461, published on 10.01.2012 Bull. No. 1].

This SUV aircraft, supplemented by a digital integrated communication module (Fig. 2, item 18), which made it possible, due to functional integration, to completely or partially exclude a significant part of the hardware from the onboard set of radio telemetry equipment (Fig. 1, item 9, 10 , 11), the functions of which it performs with its software and hardware, connected by inputs to the control panel of a set of radio telemetry equipment (Fig. 2, pos. 12) and specialized outputs / inputs with blocks for encrypting voice information and data in radio telemetry networks (Fig. . 2, pos. 19, 20), connected by their inputs / outputs to the transceivers of the on-board set of radio telemetry equipment for receiving / transmitting voice information and data when interacting with aircraft and control points (CP) equipped with telemetrically associated equipment (Fig. . 2, pos. 8), and outputs / inputs to the computing system (Fig. 2, pos. 5) for reading and receiving via multiplex communication lines signals of interaction with the aircraft's own avionics with the issuance of the results of interaction to the "crew" for display and registration (Fig. 2, pos. 6, 7), also connected by control inputs / outputs to the aviation terminal of integrated communication, navigation and data exchange of the OSNOD system for transmitting / receiving voice information and data over a multiplex communication line in anti-jamming modes (Fig. 2, pos. 17) or, in the presence of a common MSD avionics aircraft, connected by its inputs / outputs to the MSD avionics aircraft multiplex information exchange lines for information interaction with the computer system of the aircraft (Fig. 2, pos. 5), associated with the integrated controls and indication of the cockpit of the aircraft (Fig. 1, pos. 6, 7, 12, 13, 14, 15, 16,), in the proposed technical solution is selected as a prototype [RF Patent No. 2551267, published on 05/20/2015 Bull. No. 14].

SUV aircraft of the prototype in different configurations is used on aircraft of the 4th generation (accepted for supply and modernized aircraft) and is installed on experimental batches of aircraft of the 5th generation (under construction and projected aircraft) in order to ensure the possibility of forming mixed battle formations and organizing mutual exchange data between aircraft, significantly increasing their combat effectiveness, providing the possibility of mutual exchange of voice information and data, both between aircraft and aircraft with ground (air) command launchers (guidance), equipped with equipment telemetrically connected with aircraft aircraft equipment, in two independent by radio frequency bands for communication systems:

- in the first network, tentatively called the "data exchange system of a typical communication complex" (SOD TCS), by means of transceivers and terminal devices for processing information onboard a set of radio telemetry equipment (Fig. 2, pos. 8, 18, 19, 20);

- in the second network formed by the "aviation terminal of integrated communications, navigation and data exchange" (AT OSNOD), the onboard set of radio telemetry equipment (Fig. 2, item 17).

It is known that the communication channels of aircraft and launchers are built on the principle of a centralized network using the “REQUEST-RESPONSE” method, while the initiator of “INQUIRIES” is always the launcher or the commander of the general combat formation of an autonomous group (grouping) of aircraft, depending on the flight task. So, for example, in the communication network of the SOD TCS, at the signal of the commander of the general combat order of the aircraft in a closed telephone mode, the grouping of the aircraft switches to the mode of mutual data exchange according to the cyclogram, which automatically adapts to the operational-tactical situation in the air, significantly reducing the data exchange time between LA. The AT OSNOD communication network is activated in conditions of powerful electronic countermeasures and provides the reception / transmission of voice communication and data between aircraft with high reliability in issuing and executing orders to attack targets through the use of special signals in the communication network with protection against deliberate interference created by conditional electronic warfare enemy.

Data exchange in communication channels is carried out by messages (codegrams), each codegram is transmitted to the communication channel in the form of a set of words, while the word, as a rule, is represented by a 24-bit or 32-bit code, the bits of which, depending on the location, carry a certain semantic load according to its functional purpose. Each word in the codegram has a synchronous-address part for synchronization and determination of its purpose.

The functioning of the communication networks SOD TCS and AT OSNOD is based on the use of a "network matrix" (Fig. 3) in the service address part (SAC) of the message, which, like the entire message, is presented as a sequence of binary characters in the data exchange codegram. In the HSA, which determines the construction of the entire structure of the codogram, a certain resource of bits of binary code information is allocated, conditionally named in the technical proposal as a “feature indication field” (PIP), that is, fields for determining the presence of features in the communication network, which are used to select the direction of data exchange, assessing the current state of network addresses in the communication network and organizing the interaction of aircraft in a group (groupings) and with launchers in the process of scheduled pre-flight preparation of aircraft and in the process of functioning of communication networks at the request of launchers by an aircraft grouping, while as a launcher, group actions can be ground or air command launcher or commander of the general combat order of the aircraft grouping.

In the "network matrix" of the HAS codegram of the SUV aircraft of the prototype, the resources of the "field of indication of signs" allow in the communication network to solve the problems of accreditation or exclusion of communication subscribers (aircraft in communication networks with launchers), adapting the network to the planned formulation of a combat mission or to the operational-tactical situation, directly generated in the air. At the same time, the indication of signs of the current state of network addresses in the communication network is presented as follows:

- "00" - a sign free for any subscriber who has passed accreditation on the communication channel at the system (unique) address, set during the pre-flight preparation of the aircraft, or which is determined during the flight during the procedure for the state identification of the aircraft;

- "01" - a sign of the network address by which the LA PU confirms its readiness to accredit a known subscriber (LA). In this case, the system address is assigned to the subscriber (LA) before the start of his interaction with the PU;

- "10" - network address, the owner of which is accredited on the communication channel of the PU, and to which the PU does not prepare an appeal in the network;

- "11" - network address, the owner of which is accredited on the communication channel with the PU, and to which the PU is preparing an appeal in the network.

The content of the subscriber part of the "network matrix" in subscriber messages is always duplicated from the messages received from the PU. The address part of the "network matrix" (Receiver Address and Source Address) determines the direction of transmission of the current message:

- codes "0001" ... "1100" - network addresses of communication subscribers. In messages, the PU is used to identify the subscriber to whom the current message is addressed (Receiver address). In subscriber messages, it is used for self-identification (Source address).

- "0000" - PU address. In messages, SP (Source Address) is used to indicate that there is no scheduling of the accreditation procedure for subscribers who have not been assigned network addresses in advance. The code "0000" is always used by subscribers (accredited or accredited by network address) to contact the PU (Receiver Address);

- "1111" - the address of the launcher of the aircraft. It is used only by PU (Source Address) to indicate the scheduling of the accreditation procedure for subscribers who have not been assigned network addresses in advance.

This "network matrix" as a component of the HAS codegrams for data exchange in the communication networks of the SOD TKS and AT OSNOD SUV aircraft has been successfully tested in training flights of the interaction of a homogeneous group of aircraft from aircraft of the same type for the purpose of the Su-27SM, Su-34, Su-35 on which as part of the avionics, identical sources and consumers of information are used and informationally compatible homogeneous code structures of words are formed.

However, at present, on aircraft of various branches and types of troops and on aircraft of different purposes within each type of troops, non-identical sources and consumers of information are used as part of the aircraft avionics and, as a result, heterogeneous structures of codograms (with a difference in location and functional purpose of bits information in 32-bit code words).

This is due to the fact that SUV aircraft of various branches and types of troops and aircraft with different purposes within each type of troops and even a number of generations of the same type of aircraft were designed by different enterprises - developers and optimized for the functional tasks of SUV aircraft of a particular type of aircraft. So, for example, standard messages for the Su-27SM and Su-30SM have a set of commands similar in composition, but differ in the numbering of commands and the format of the messages with which standard messages are delivered to the aircraft. Messages for the Su-30SM have a “network matrix” of the prototype in the structure of the HSA messages, but it does not contain resources for reformatting alien codegrams. In addition, a number of aircraft, such as IL-76, have the ability to transmit information in communication channels by such technical means that do not have their own mechanism for identifying the transmitted information.

Such technical means also include the modern OSNOD aviation terminal, which completely forms the codegram of messages transmitted to the radio channel, which ensures transparency in radio telemetry channels, but also does not have its own means of identifying the functional purpose and structure of the information part of the codegrams.

Despite the transparency of radio telemetry communication channels by radio frequency ranges, as well as by types of modulation and manipulation, the code structures of words and the volume of data transmission / reception on aircraft for different purposes in various branches and types of troops are informationally incompatible, therefore the creation of a mixed homogeneous grouping of aircraft from various for the purpose of an aircraft with non-identical sources and consumers of information in the avionics of an aircraft is not possible without modifications and high economic costs to carry out work on the unification of the avionics of most aircraft (Fig. 4).

In addition, there are a number of special-purpose aircraft, for example, military transport aviation (VTA), where weapons are not installed and weapons control systems are not required, but there is a need to include them in a mixed group with combat aircraft and organize mutual data exchange between aircraft in group to improve the security of the BTA escort. The task, conventionally called "support" at this time can only be provided through voice communication channels, which not only limits the possibility of including this type of aircraft in mixed groups, but in general, in some cases, excludes the possibility of their use in radar detection zones by a conditional enemy, since the airborne radio-electronic systems of the VTA in the voice communication channels are not equipped with means of protection against deliberate interference, and in the data transmission channels the structures of their codograms are informationally incompatible with the codegrams of the SUV aircraft, which can be assigned to accompany the VTA aircraft (Fig. 5).

The results of the analysis found that in the presented “network matrix” of the HSA of the basic codogram of the prototype, there are not enough resources to initialize subscribers in communication networks for the mutual exchange of data of the entire spectrum of different aircraft of the armed forces and types of troops, on which heterogeneous sources and consumers of information are installed and resources for initiating commands for reformatting heterogeneous structures of codograms in communication networks for data exchange of various types of aircraft into a form accepted for processing by sources and consumers of information on each aircraft.

These shortcomings are eliminated by the proposed technical solution.

The objective of the present invention is to provide the possibility of expanding and using the data of the aggregate information field for the simultaneous combat use of aircraft weapons, in order to increase the effectiveness of combat operations when they are carried out by a mixed group of aircraft, consisting of front-line aviation (fighter-interceptors, front-line bomber aircraft, helicopters), long-range aviation (strategic and military transport aviation) and command ground (air) launchers, due to the use of a control and routing module (CRM) on the aircraft as part of a set of radio telemetry communication equipment, which ensures information compatibility of codegrams when transmitting / receiving data and voice information on radiotelemetric channels for the mutual exchange of information in the SOD TCS and AT OSNOD networks in the interests of centralized collection of data on the forces and means of a mock enemy, determination and optimal selection of the most critical air, ground and sea e objects and automatic transmission of orders for their attack and transmission / reception of information of mutual support for front-line fighter aviation and special-purpose aviation, for example, long-range strategic and military transport aviation during their interaction in a mixed group (grouping), for example, in the tactical task “escort on the route" in order to determine the safest areas and flight routes to overcome the air defense of a mock enemy using modern means of electronic warfare.

Formation of a homogeneous mixed grouping from aircraft with heterogeneous equipment of avionics aircraft and aircraft of various functional purposes in the branches and types of troops, with the possibility of centralized collection of information from each aircraft to the launcher of the grouping or to the aircraft of the commander of the general combat formation, expands information about the targets and objects of the mock enemy along the width and depth of the front, allowing you to optimize group actions, radically increasing the combat effectiveness of a mixed aircraft grouping.

The technical result is achieved by the fact that in an SUV aircraft, including a multifunctional onboard radar station and an optoelectronic system, an onboard set of guidance equipment and an onboard set of navigation equipment with a flight information sensor, a set of indicators of aiming, navigation and flight information, as well as a computer system associated with the listed devices and with the input of the tactical situation indicator for displaying to the "crew" the results of the interaction of aircraft and data recording, a digital integrated communications module connected by its inputs / outputs to the transceivers of the onboard set of radio telemetry equipment for receiving / transmitting information and data when interacting with aircraft and control points equipped with telemetrically connected equipment, outputs / inputs to the computer system, inputs to the control panel for operating modes in the data exchange system and receiving via multiplex communication lines control signals for a set of radio telemetric communication equipment, specialized outputs/inputs with blocks for encrypting voice information and data in radio telemetric communication networks, and control inputs/outputs to the aviation terminal of an automated system for unified communications, navigation and data exchange for transmission/reception via the multiplex information communication line, the control and routing module additionally installed in the on-board set of radiotelemetry communication equipment is connected by its inputs / outputs of the multiplex lines for receiving / transmitting information control signals and multiplex information exchange channels with a digital integrated communication module and an aviation terminal of the unified communication system, navigation and data exchange, connected by outputs / inputs to the decisive task of controlling and distributing information in the internal data exchange network of the radio-electronic equipment of the aircraft in computer system, provides information compatibility of messages (codograms) in the channels of receiving / transmitting information and data when interacting with aircraft and control points equipped with telemetrically connected equipment, but different in the structure of construction and coding of information data, and adaptation of the aviation terminal of the unified communication system, navigation and data exchange to the on-board electronic equipment of aircraft of various functional purposes for the organization of homogeneous (information-compatible) mixed aviation formations of various branches and types of troops (Fig. 6).

In the presence of a common trunk data bus of the aircraft and the integration of a set of indicators for sighting, navigation and flight information, a control panel for the operating modes of radio telemetry and an indicator of the tactical situation into a single structural and functional device of the cockpit of the aircraft, a multifunctional control panel-indicator (MFPI) connected by inputs / outputs with the MSD, the control and routing module of the set of radio telemetric communication equipment is connected by its inputs/outputs of the multiplex information exchange to the MSD for interaction with the on-board radio-electronic equipment of the aircraft.

When integrating the control and routing module and the aviation terminal into a structural and functional complex of technical means of the unified communication, navigation and data exchange system, ensuring the use of the 5th and 6th generations of aircraft in homogeneous groupings with 4 and 4++ generations of aircraft of the genera and types of troops, this constructive-functional complex of technical means of the unified communications system is connected by inputs/outputs to the digital integrated communication module of the radiotelemetry communication equipment set and outputs/inputs of the multiplex information exchange to the common MSD for interaction with the onboard radio-electronic equipment of the aircraft.

With a deep structural and functional integration of transceiver devices, a digital integrated communication module and speech and data encryption units into an integrated series of multifunctional transceiver modules (MTTM), which are devices of a structurally modular design for each radio frequency range of a set of radio telemetry equipment, the control module and routing from the constructive-functional complex of technical means of the unified communications, navigation and data exchange system is connected by outputs/inputs to each MTPM selected for use in the aircraft weapon control system.

Thus, the technical solution proposes:

- MUM (Fig. 6 pos. 21) to give its own identification address and, when integrating control, monitoring, indication and registration units (Fig. 6 pos. 6, 7, 12) into a single structural and functional device MFPI of the aircraft cabin, if available common MSD avionics aircraft, connected by channels of multiplex information exchange with the computer system SUV LA, connect it to interact with the digital integrated communication module, the aviation terminal of the OSNOD system and the computer system SUV LA with its inputs / outputs of the multiplex information exchange channel to the MSD avionics aircraft (Fig. .7, item 21);

- MUM, when integrating with the aviation terminal of the integrated communication, navigation and data exchange of the OSNOD system into a single structurally and functionally connected complex of technical means of the OSNOD system (KTS CO), connect the outputs / inputs to the digital integrated communication module of the radio telemetry equipment set, and the inputs / outputs of the multiplex channels of information exchange to the MSHD avionics aircraft, controlled by a multifunctional console - an indicator of the computer system of the SUV aircraft (Fig. 8, pos. 22);

- MUM, integrated with the aviation terminal of the integrated communication, navigation and data exchange of the OSNOD system into the complex of technical means KTS CO, with deep functional and constructive integration over the radio frequency ranges of transceivers, a digital integrated communication module and speech and data encryption units into an integrated series (from 1 ... to K) multifunctional transceivers of a modular design in each radio frequency range of the onboard set of radio telemetry equipment, connect outputs / inputs to each device selected for use in SUV aircraft, and connect inputs / outputs of data exchange channels to the MSD avionics aircraft, controlled by a multifunctional remote-indicator of the SUV aircraft computer system (Fig. 9, item 23).

The use in SUV LA of the control and routing module, indicated by a dotted line in FIG. 6, 7, 8, 9, 10, allows its hardware and software to perform data processing: formatting (packing) or unpacking and reformatting in the modes of transmitting or receiving codegrams, respectively, and to solve the problem of choosing the direction of movement of these codegrams as part of the avionics of an SUV aircraft.

In essence, the MCM is a small-sized on-board digital computer, presented as a set of functional sub-units interconnected by the PCI Express system bus and the Compact PCI backup bus, which is structurally designed into an independent unit that performs the following functions:

- a specialized digital computer with an open programming architecture and the ability to rewrite software through the use of a service "data input device" (ATD) MUM;

- router of information flows between onboard systems and ground consumers of information using radiotelemetric communication channels;

- control of equipment from the set of radiotelemetric communications;

- speech informant;

- a telephone communication module with a speech-transforming device;

- interaction with avionics equipment.

The power supply of the MUM is carried out from the onboard power grid (BE) of the aircraft.

The block diagram of the MCM and its interface of information input/output channels are shown in Fig. 10 (pos. 21).

To warm up the MUM before starting its operation, the on-board power supply network (BE) of the aircraft supplies power to the input of the sub-unit of the secondary power source (Sat. 21-4), the outputs of which are electrically connected to the sub-unit of the hub board (Sat. 21-2) and to the sub-unit of telephone communication connected electrically, functionally and structurally, with the speech-transforming device board (Sat. 21-3), and the outputs / inputs are electrically and functionally connected by control signals to the subunit of the central processor (Sat. 21-1), electrically, functionally and structurally connected, with a mezzanine board for input-output of bipolar code signals according to GOST 18977.

All MCM subunits are functionally interconnected by outputs / inputs for informational interaction with the intrablock PCI Express bus of the main and backup Compact PCI. The RCM interface in the number of "N" input-output channels (from 1 ... to "K" input-output channels of each type are installed for specific tasks of the RCM configuration options) contains:

- input channels for potential one-time commands;

- I/O channels of bipolar serial code according to GOST 18977;

- input-output channels of one-time code commands;

- input-output channels of multiplex information exchange;

- input-output channels according to the Ethernet standard;

- input-output channels according to the RS 485 standard;

- input-output channels using USB technology;

- voice telephony input-output channels;

- input channels for alarm sensors;

- subscriber communication input channels.

The MMM is connected by means of an interface to the multifunctional remote-indicator of the aircraft avionics computer system, which ensures its operation as part of the SUV aircraft. The operation of the MUM begins with a signal from the aircraft avionics control system to turn on, arriving at the input of the input channel for potential one-time commands of the concentrator board (Sat. 21-3), connected by outputs / inputs to the central processor (Sat. 21-1), electrically connected to the board - input-output mezzanine in accordance with GOST 18977, the outputs / inputs of which are intended for communication with aircraft avionics devices using bipolar code signals in communication channels in accordance with the requirements of GOST 18977.

It is known that the procedure for the interaction of an aircraft within an aircraft group and with a control point is based on the use of a “network matrix” in the service-address part of messages that carries signs and commands, the use of which allows centralized control of the aircraft group at the current time. At the same time, the “network matrix” of the prototype, according to the algorithms for its construction, contains signs of initializing the current state of network addresses in the data exchange network for the purpose of accreditation only for communication subscribers with homogeneous codegram structures.

In the technical solution for processing heterogeneous structures of codograms in the MCM, the following are proposed:

- "unified network matrix" (USM) of HSA codegrams with an optimized resource in terms of the number of digits of bits of binary code information in the network matrix for the formation of indication signs and initiation commands for the organization and operation of communication networks for the exchange of aircraft data with heterogeneous structures of codegrams;

- a method for the formation and use in the MMM of a "unified network matrix" of the HSA codegram, as an add-on (shell) for recording, storing and using indication signs for the organization and operation of communication networks according to the plan assigned during the pre-flight preparation of the aircraft, or upon request in the process of execution operational-tactical task directly in the air and commands to initiate certain actions with the adopted codegram to select the route of its movement to the information consumer directly or previously to reformat its structure by the MUM hardware and software into the form accepted for processing by the consumer, thus providing information compatibility of codegrams in radiotelemetric channels of mutual data exchange in the communication networks "SOD TKS" and "AT OSNOD" in order to form mixed groups (groups) of aircraft with a heterogeneous composition of avionics of various branches and types of troops;

- as a variant of the proposed invention, algorithmic methods for forming the USM structure as a shell for heterogeneous codegrams, endowing it with addresses, accreditation and functioning in data exchange networks of an almost unlimited number of aircraft and methods for processing USM, providing information compatibility of heterogeneous messages in communication networks of data exchange channels without carrying out more economically costly unification of aircraft avionics.

To process heterogeneous codegrams, it is proposed to supplement the resources of the HSA message (codegram) for the use in its structure of an additional "unified network matrix", conditionally called in the sentences "codegram shell", in the "information fields" of which the necessary signs and commands for the procedures for generating codegrams for transmission are recorded. and processing of codegrams at the reception.

Resources in the HSA structure of the codegram in the form of digits of binary code information bits allocated for recording features and commands in USM can be conditionally represented by information fields in Fig. eleven:

- field for indicating the attributes of the source of the message - the form of the source of the message (FIS), in which signs can be additionally indicated according to the ownership of the PU;

- indication field of "signs of subscribers' addresses" (SAA) (from k=1 to M), M=12 when controlled from one PU;

- the field for indicating "network addresses" (NA) in communication networks to perform the functions of identification (identification) and accreditation of communication subscribers, presented in the USM in two parts: devices "(SA - PRD);

- indication field of the "sign of transit of the codegram" (PTK) in the adopted structure;

- field for initiating commands for reformatting codograms "data packaging format" (FUD) presented in two parts: "type of packaging" (TU) - information field for indicating signs of processing codograms and initiating commands to run the program for repacking (reformatting) the structure of the codogram, "content of packaging" (CS) - an information field for indicating signs of processing a codogram and initiating commands for launching a program for converting (translating) the content of received codograms into a reformatted package, into a structure transparent for processing.

The information fields "Data packaging format" contain technical resources for:

- "development reserve" (RR) - an information field for indicating signs for using the operability of a communication network in communication check modes without an information component in the codogram and a possible expansion of functional tasks;

- field indicating the signs of "retransmission of messages" (RT);

- field indicating the signs of the "guidance mode" (PH);

- a field for indicating the signs of the "address part" (AP) to determine the presence, format and number of communication subscribers;

- field for indicating the signs of the "rank (status) of subscribers" (RA);

- the field for initiating commands of "temporary insertion" (BB) to determine the exact time of receiving the codegrams and to exclude false imitation codegrams from processing.

During the pre-flight preparation of the aircraft in the MCM, the program for implementing the USM construction algorithms is recorded and the indication signs and initiation commands necessary for functioning in the communication networks of mixed groups of various types of aircraft with heterogeneous sources and consumers of information are entered into the “information fields” of the USM structure indicated in the text above. , but with the obligatory equipment of LA MUM equipment. As "information fields" for recording signs of indication and USM initiation commands, the resources of random access memory (RAM) and read only memory (ROM) of the central processor MUM are used. The information fields of the UMS, which uniquely determine the structure and order of processing in the modes of reception and transmission of each heterogeneous codegram and its oriented set of implementations in the form of homogeneous codegrams, are proposed to be allocated in the "database" of the MCM ROM. The information fields of the UMS for recording signs of the structure of the current codegram are allocated in the RAM of the MUM.

It is proposed to allocate a certain part of the hardware and software resource of the MLM to the “distributed device of the conceptual analyzer” (RUKA) conditionally named in the technical solution - a virtual device that exists in the form of a software product that is part of the general software of the MMM. The scheme of functional connections of the distributed device of the conceptual analyzer MCM is shown in Fig. 12. The structure of the distributed device of the conceptual analyzer includes functional elements:

- stack (accumulator) (pos. 24);

- script event sequence interpreter (pos. 25);

- a storage subsystem (fact base) of current knowledge of the state of controls and information of aircraft avionics transmitters in the form of a hierarchical system of knowledge frames of sets Si (from 1 ... 1 ... to S) of structures of heterogeneous codegrams (pos. 26);

- a storage library (database) of an oriented set Mj - (1…j…up to M) implementations of event procedures in Si - the structure of a homogeneous codegram (pos. 27);

- a subsystem for generating an individual method of symbolic description of the system process associated with the state of information sensors and controls of the aircraft avionics at the current time (pos. 28);

- storage library (databases) of typical scenarios for the operation of SUV aircraft (pos. 29);

- storage subsystem (knowledge base) of the system operation history protocol (item 30);

- a subsystem for overcoming "crisis situations" (pos. 31).

The basis of the "distributed device of the conceptual analyzer" (RUKA) of the MCM (the block diagram of the logic of which is shown in Fig. 13) is the principle of comparing the shell of the MCM of the current in time codegram entering the MCM RAM with the "mask" also pre-recorded in the MCM RAM » UMS shell (containing only the UMS structure with a record in the information fields of the necessary features and commands for processing the codegram). If the received UMS shell of the codegram completely coincides with the “mask” of the UMS shell, pre-recorded in RAM, a signal is generated for removal (subtraction of bits of information from the ACS allocated to the UMS structure) and the codegram is automatically processed as homogeneous, adopted for this type of SUV aircraft . If the currently accepted UMS shell does not match the “mask” of the UMS shell, signs and commands are distinguished by the comparison method for real-time reformatting of the received codogram into the structure accepted for processing on this type of aircraft. Reformatting codegrams provides a distributed concept analyzer device.

The codegram received by the transceiver of the radiotelemetry communication set over the data exchange network of the SOD TKS or AT OSNOD enters via one of the channels of the MUM interface (Fig. 12) into the stack (accumulator of a binary sequence of bits of information) pos. 24, connected by outputs / inputs to the interpreter pos. 25, connected by its outputs/inputs with the storage subsystem (fact base) of the current knowledge of the state of functional sensors and controls of the aircraft avionics pos. 26 and with the library (database) of the set M - the implementation of the event procedures in Si - the structure of the homogeneous codegram pos. 27, and the input with a storage library (database) of typical scenarios for the functioning of the SUV system (avionics aircraft) pos. 29, connected by inputs/outputs to the storage subsystem (fact base) of the current knowledge of the state of functional sensors and controls of the aircraft avionics pos. 26 and connected by inputs / outputs with the system for overcoming "crisis" situations pos. 31, and stack pos. 24 other outputs/inputs connected to the subsystem for generating an individual method of symbolic description of the system operation process pos. 28, the outputs of which are connected to the input of the storage subsystem (fact base) of the current knowledge of the state of the functional sensors and controls of the avionics pos. 26 and to the input of the protocol storage subsystem (history) of the system operation pos. 30, interconnected by inputs / outputs, and outputs with a system for overcoming "crisis" situations pos. 31. The current codegram enters the RAM MUM. The ARM compares the USM of the received USM codegram with the base codegram stored in the MUM ROM. When exchanging aircraft data with homogeneous codogram structures in USM, there are no signs of initiating commands for reformatting the codogram, therefore, RUKA includes a program for implementing the “homogeneous codogram processing algorithm” in accordance with the indicated USM signs. If there are signs in the USM of the received codegram of initiating commands for reformatting the codegrams, the program of the “heterogeneous codegram processing algorithm” (Fig. 13) is switched on in accordance with the algorithms of the distributed device of the MCM conceptual analyzer. The technical solution proposes a method for comparing Si - codegram in a character-by-character record in the "fact base" of the RAM in the current real time and Mi - codegram in the "database" of the ROM, pre-recorded in the MUM. The subsystem for overcoming "crisis" situations is activated when a failure occurs in the processing system of the received codegram, caused by the loss of part of the message under the influence of interference, including intentional, in the radio channel. For this purpose, the “knowledge base” storage subsystem of the RUKA MUM operation history protocol is used in the form of a certain memory resource in the MUM ROM, where the received codegrams are constantly recorded and knowledge is accumulated. The accumulated knowledge is proposed to be used for interpolation with a certain error of a part of the lost bits of information as a result of interference. At the same time, the more knowledge is accumulated in the process of practical operation of the MCM in time, the smaller the error of interpolation of the lost data in the received codegram. Thus, a machine intelligence algorithm is proposed on the side of receiving codegrams, which improves the quality of communication in an SUV aircraft. Restoration of bits of information in the codegram is carried out by the “subsystem for generating an individual method for character-by-character description of the system process” RUKA MUM according to interpreter commands using MUM hardware. The expansion of the information fields of the "address part" in the "Unified network matrix", in contrast to the "network matrix" of the prototype, allows you to increase the number of subscribers in the communication network, and the additional introduction of information fields: "Message source form", "Data packaging format", " Message relaying”, “Temporary insertion” and a number of other information fields, not only solves the target problem of the proposed technical solution, but also significantly expands the functionality of the interaction between the aircraft and launcher, for example:

- the presence in the USM HSA of the codogram of the information field "Message source form", which uniquely determines the source of the message, allows you to increase the number of signs of presence in the network of aircraft that are not yet PU subscribers in the "Address part" of the "Unified Network Matrix";

- signs (bits of information), in the "network matrix" version of the prototype in the "Address part" field, identified the PU as the source of the message with the network address "0000" or "1111" and, by default, was a command for both control and presence in the network PU only for subscribers without accreditation, combining group activities and interaction with PU, which caused inconvenience in operation. Therefore, in the “Unified Network Matrix” of the HAS of the PU message, the parameter related to the message source address: “Source Functional Parameter” is highlighted as a separate feature in the “Form” information field, while it loses the function of the PU network address, but completely acquires the main control function , which is directed to all subscribers located with and without accreditation in the PU control network:

- "0000" - the command "Disable waiting in the channel for the next message of the PU". The command is intended for subscribers without accreditation, who combine group actions and interaction with the CP (should be used only in networks without the relay function);

- "0001" ... "0110" - a command to switch to the channel with the corresponding number: No. 1 ... No. K. The commands are intended for all subscribers without accreditation (should be used only in networks without a relay function);

- "1111" - the command "Wait in the channel for the next message PU". The command is intended for subscribers without accreditation, who combine group actions and interaction with the CP (should be used only in networks without the relay function);

- "1000" - the command "Prohibition of waiting in the channel for the next message of the PU". The command is intended for subscribers without accreditation, who combine group actions and interaction with the PU (should be used only in networks with the relay function);

- "1001" ... "1110" - a command to switch to the channel with the corresponding number: No. 1 ... No. K. The commands are intended for all subscribers without accreditation (should be used only in networks with a relay function);

- "0111" - the command "Wait in the channel for the next message PU". The command is intended for subscribers without accreditation, who combine group actions and interaction with the CP (should be used only in networks with the relay function).

In the "Unified network matrix" of HSA messages of the PU, in contrast to the "network matrix" of the prototype, the signs of the need for relaying are placed in a separate independent field "Message relaying", which contains only the network addresses of the subscriber or subscribers for whom the current message is intended, while:

- "0001" - "1101" - network individual or group "0000" - network circular address of subscribers in the channel;

- "1110" - network individual or group address, which can be assigned only by a single object, the presence of which in the PU network is not limited in time.

In CP messages (these are control commands and data) generated to subscribers, the "Source Functional Parameter" always contains the value of the network address under which the subscriber was accredited in the CP channel: "0001" ... "1100", "1110" - network addresses, under which subscribers were accredited in the channel.

In messages (these are receipts for control commands and data) generated by subscribers, in the information field of the "Receiver Functional Parameter" features, commands are always initiated to duplicate the content of the "Source Functional Parameter" message that was received from the PU.

It is proposed to use the information field of the characteristics "Source functional parameter" to plan interaction with aircraft that may be present in the network, but are not yet PU subscribers.

The “Unified Network Matrix” makes it possible to have information on the PU about the current state of subscribers (LA) during almost every communication session, not only the aircraft that are under its supervision, but also the rest of the aircraft that are currently in the network, which allows informing their aircraft about the procedures planned by the launchers through the state of network address signs (CA 1 ... CA N) for organizing, for example, a mixed group of aircraft directly in the air.

Thus, in general, the information field of UMS signs and commands is a multifunctional parameter that determines the purpose of the current message and the structure of the information transmitted in the message, allows you to identify a wide range of information structures, and also, in the case of combining objects into groups according to functional tasks and the value of the network address , expand the number of accompanied objects to the required value.

In case of group addressing, individual addressing of objects in a group can be carried out with the help of a sub-address, the value of which is proposed to be determined by features in the information field "Package contents" of the data packaging format.

The information field of the features "Data packaging format" is also proposed to be used as a system message identifier in the aeronautical communication system, which allows you to divide messages into categories, which is determined by the "Package content" parameter, for example:

- commands for managing the complex;

- channel accreditation;

- downloading a communication plan over a radio channel;

- identification of the subscriber by sub-address, provided that the network address is used as a group address;

- navigation data;

- data of the target environment.

The "Package Type" parameter is proposed to be used to identify the structure of the content of codograms by belonging to the types and types of aircraft troops, sets and structure of data or commands within individual message categories, for example:

- category of types and sets of commands;

- category of sets of navigation parameters (type, composition and word length of parameters).

The information field "Type of packaging" is proposed to be used to record additional features for the execution of commands to reformat the received information into the structure of the codogram transparent to the consumer.

The information field "Reserve" UMS, added in contrast to the "network matrix" of the prototype, provides opportunities for the functional development of communication networks for data exchange in SUV aircraft.

It follows from the above description that the information field for recording the codes of features and commands of the "Unified Network Matrix" not only retains the characteristics of the "network matrix" of the prototype, but also significantly expands the functionality of interaction and control of the aircraft both within the aircraft grouping and the aircraft grouping and individual aircraft accredited and not accredited in the communication network with the control point, ensuring prompt switching of communication subscribers between active communication channels. At the same time, the PU can simultaneously provide independent operation of up to six communication channels and increase the number of objects accompanied by the PU at individual network addresses from 12 to 14 and organize networks with a message relay function. The PU that generates the corresponding states of USM signs can initiate communication with any subscriber, change the network configuration depending on the situation, build a data exchange sequence diagram, determine the time spent by each subscriber (LA) in the communication network, and practically manage the allocated information resource of the communication channels of the group of aircraft.

To solve the target task of technical proposals to ensure the information compatibility of heterogeneous codograms in data exchange networks in the information fields of the "Unified Network Matrix" of the HSA of the structure of the codogram formed by the MCM, codes of features and commands are recorded that are used to enable the MCM control commands to perform certain actions:

- for packing / unpacking a codegram with heterogeneous structures (as an attachment following the example of using a postal envelope);

- determination of ownership and structure of the adopted codegram;

- performing actions to reformat (transform) the received codegram into a transparent structure for the consumer;

- selection of the direction of transmission of the codegram to the consumer.

Thus, the goal is achieved not by creating a unified codegram, but by creating a “unified network matrix” for heterogeneous codegrams, which makes it possible not to modify a variety of avionics and save the available display means with the same symbolism or designation of these instructions on the aircraft indicators, which was adopted, for example , on the SUV aircraft of the prototype (Fig. 14) and not to spend significant financial resources on the retraining of the flight personnel of aircraft of various branches and types of troops.

The program for the implementation of the algorithms for identifying an incompatible codegram and its reformatting into a transparent codegram structure for the consumer is carried out by the MCM central processor on the receiving side of each aircraft, or on the aircraft of the commander of the general combat order of the aircraft, or on the ground (air) based command launcher, depending on the assigned flight tasks.

The proposed technical solution for the installation of an SUV LA MUM into the radio-electronic equipment, which provides the implementation of a method for organizing interaction in communication channels of homogeneous mixed formations of a group (groups) of aircraft of various branches and types of troops with different structures of codegrams and allows:

- quickly change the configuration of network subscribers, without disrupting the work of subscribers to solve other connected tasks;

- to build a cyclogram of interaction between PU and network subscribers, based on the actual number of accompanied subscribers, which makes it possible to optimally use the information resource of the communication channel;

- to reduce the time spent by subscribers in the CP communication channel and to optimize the use of CP technical means by aircraft groupings for solving other connected tasks;

- radically increase the combat effectiveness of mixed aircraft groupings by organizing mutual data exchange and obtaining a larger amount of aggregate information for solving operational-tactical tasks.

The results of the experimental verification of the proposed technical solution in training flights on Su-27SM, Su-30SM, Su-35, Il-76 aircraft have established the information compatibility of messages, the code structures of which have a different set of commands, differ in command numbering and information presentation forms. parts of messages.

The use of the claimed aircraft weapon control system allows to obtain a new quality: to ensure, unlike analogue and prototype, information compatibility of codegrams in the interaction of mixed aircraft groupings, different in technical appearance and functional purpose, radically increasing their combat effectiveness when performing joint operational-tactical and strategic tasks.

This technical solution is supposed to be used on almost all types of combat aircraft and helicopters of the RF aviation by installing a control and routing module in the SUV aircraft.
