The invention relates to aviation radio communication systems and can be used for the exchange of data and voice information in the air-to-air radio communication channels between aircraft (AC), in the air-to-ground radio communication channels between the aircraft and ground complexes and in the space radio communication channels -air "in various ranges from 2 MHz to 6 GHz, in the presence of both broadband natural interference and narrow-band technical interference, as well as for the organization of automatic and automated data exchange in special aviation communication networks.

Currently, a complex of onboard digital communications (KBSTsS) is used to exchange messages between the onboard radio electronic equipment of the aircraft and ground services [1], taken as a prototype.

The disadvantages of this KBSTsS include:

- lack of means of organizing automatic and automated data exchange in air-to-air radio communication channels between aircraft and in air-to-ground radio communication channels between aircraft and ground complexes;

- the presence of a significant number of data exchange lines and point-to-point control.

The technical solutions of the prototype do not allow organizing the automatic delivery of tactical information to the pilot and broadcasting it for interacting aircraft, and also do not allow flexible and efficient use of the resource of on-board electronic computers (computers) when organizing communication through channels of different ranges.

The main technical problem to be solved by the invention is to expand the functionality of the complex of onboard digital radio communications, namely, the implementation of automatic and automated data exchange between interacting aircraft, optimization of the use of the frequency resource of radio equipment and the computing resource of specialized onboard computers, as well as improvement of weight and size. characteristics by reducing the number of intracomplex connectors.

The specified technical result is achieved by the fact that in the complex of onboard digital communication facilities, including a control and routing module connected via a single redundant bus of command and information exchange and a high-speed bus for transmitting integrated information to onboard radio electronic equipment, and low-frequency telephone circuits to the pilot's audio headset, three-channel broadband communication module DKMV-MV / DMV1 range, satellite communication module, transceiver module DMV2 range, information security module connected to the control and routing module, while the three-channel broadband communication module DKMV-MV / DMV1 range is connected to the control and routing module by low-frequency telephone circuits, an additional module for processing command and navigation information was introduced, connected via a high-speed bus of command and information exchange to onboard electronic equipment, and via a high-frequency data exchange line to a three-channel broadband to the communication module DKMV-MV / DMV1 of the range, while the wide-range communication module DKMV-MV / DMV1 of the range, the satellite communication module, the transceiver module of the DMV2 range and the information security module are connected to the control and routing module via a single bus of command and information exchange, and the module control and routing is equipped with an additional hub card designed to manage a single redundant command-information bus using a single exchange protocol.

Distinctive features of the proposed KBSCR are:

- availability of a module for processing command and navigation information for organizing automatic and automated data exchange, optimizing the use of the frequency resource of radio equipment and the computing resource of specialized on-board computers;

- connection of the components of the complex using a single redundant bus of command and information exchange according to the "star" topology, which makes it possible to further optimize the use of the computing resource of specialized onboard computers and improve the overall weight and size characteristics of the complex.

KBSTSR is a multichannel device that is designed to receive / transmit information from the on-board radio-electronic equipment of a mobile object to an integrated antenna system of a mobile object in a wide range of radio waves from 2 MHz to 6 GHz, in the presence of both broadband natural interference and narrow-band technical interference, and also for the organization of automatic and automated data exchange in special aviation communication networks.

KBSTSR consists of seven main modules, namely: a control and routing module 1, a three-channel wide-range communication module DKMV-MV / DMV1 of range 2, forming a DKMV channel and MV / DMV1 channels of a range, a satellite communication module 3, a transceiver module DMV2 of a 4 range, the information security module 5, the CMB range 6 transceiver module, the command and navigation information processing module 7. The structure of the complex is shown in FIG. one.

The exchange of information between the modules and the delivery of control commands is carried out by the MCM 1 via the corresponding control buses and specialized buses of high-speed data exchange (Fig. 1). MUM 1 via a single redundant bus of command and information exchange I and a high-speed bus for transmitting integrated information II is connected to the on-board electronic equipment, and via low-frequency analog lines III to the pilot's audio headset. Three-channel SHMS DKMV-MV / DMV1 of range 2, module SKS 3, transceiver module DMV2 of range 4, information security module 5 are connected via the command and information bus VI with the corresponding input / output MUM 1. Module of the transceiver CMV of range 6 via a high-speed integrated transmission bus information VII is connected to the corresponding input / output MUM 1. By the circuits for receiving / transmitting analogue speech information V MUM 1 is connected to the SHMS 2. The command and navigation information processing module 7 is connected to the SHMS 2 by a high-frequency data exchange line VIII, and a high-speed command and information exchange bus IV with onboard electronic equipment.

The structure of the control and routing module 1 is shown in FIG. 2.

The module consists of a central processor 9, connected by an internal high-speed redundant bus with a hub board 8, a telephone module 10 and an interface board 11. A single redundant bus of command and information exchange VI is connected to the input / output of the hub board 8, to the input / output of the processor 9 a high-speed integrated information transmission bus VII is connected, the corresponding inputs and outputs of the telephone module 10 are connected to the circuits for receiving / transmitting analog speech information V, and low-frequency analog lines (III) the telephone module 10 is connected to the pilot's audio headset, the interface board 11 is connected to the onboard radio electronic equipment via a single redundant bus of command and information exchange (I) and a high-speed bus for transferring integrated information (II).

The operation of the complex is based on principles identical to the general principles of the prototype [2, 3] and the principles of operation of on-board communication systems [4].

The control and routing module 1 controls and monitors the status of radio communication modules 2-4, 6 and 7, as well as the information security module 5. Additionally, the control and routing module 1 provides radio communication channels switching and routing of digital radio communication packets.

Radio communication modules 2-4 and 6 provide analog-to-digital conversion of received signals, digital-to-analog conversion of transmitted signals, as well as direct control of parameters of transmitted radio signals (frequency, power, modulation type, etc.). Additionally, the modules transmit information about their status to the control and routing module 1 via the command and information exchange (VI) bus.

Also, as in the prototype, radio communication modules 2-4 and 6 after receiving from the control and routing module 1 speech or telecode information for transmission, as well as information about the formation of the radio frequency path (transmission frequency, modulation type, speed, etc.) , carry out the synthesis of the carrier frequency, modulation and amplification of the signal. When receiving information, radio communication modules 2-4 and 6 also carry out demodulation and analog-to-digital conversion of the signal with the transmission of the received information to the control and routing module 1. But at the same time, command and information exchange between radio means 2-4, information protection module 5 and module control and routing 1 is carried out via a single redundant bus of command and information exchange (VI) according to the "star" topology, where each module is connected to each one, using a single asynchronous exchange protocol, which improves the weight and size characteristics of the BSCR and increases the efficiency of using the on-board computer from the control and routing module 1.

The control and routing module 1 includes a concentrator board 8, which provides sequential issuance of control commands and information for radio equipment and information security module 5, as well as receiving information from radio means and disclosed information from the information security module 5. When information is received from the central processor 9 or from the interface board 11, the hub board 8 provides the formation of information packets for transmission over a single redundant bus command-information exchange (VI) and data buffering for the duration of the command-information exchange. Also, the hub board 8 is responsible for receiving information via a single redundant bus command and information exchange (VI) from the radio communication modules and the information security module 5 and transmitting it for processing to the central processor 9 or directly to the interface board 11.

The information security module 5 ensures the disclosure of the received information and the closure of the transmitted information using cryptographic protection algorithms in accordance with the type of information (voice or telecode).

In the additionally introduced module for processing command and navigation information 7, the information received via an independent radio channel is converted to the format of the initial data of the facility's weapons complex and is automatically transmitted via the high-speed bus of command and information exchange (IV) to the control system of the aircraft. Via the high-frequency data exchange line (VIII), the command-navigation information processing module 7 issues equipment diagnostics data to the wide-range communication module 2. The wide-range communication module 2 controls the command and navigation information processing module 7 via the high-frequency data exchange line (VIII) in terms of the radio channel parameters (frequency, modulation, etc.) in accordance with the flight conditions of the aircraft.

Expansion of the functionality of the complex in the field of communications is as follows:

- an additional command and navigation radio exchange radio link was introduced, which makes it possible to automatically convey to the pilot the sighting and navigation information of the facility's weapons complex;

- implemented the ability to conduct automatic and automated exchange of navigation information in the interests of aircraft guidance equipment between interacting aircraft;

- the internal information exchange of the complex has been optimized;

- the use of computing resources of onboard computers from the communication complex has been optimized.

Additionally, the weight and size characteristics of the KBSCR have been improved. The proposed technical solution allows to optimize the structure of information exchange in the interests of the aircraft pilot and to increase the efficiency of the deployment aircraft, in particular, front-line aircraft.
