Description

The utility model relates to airborne radio communication systems and can be used to exchange data and voice information in air-to-air radio communication channels between aircraft (AC) in air-to-space radio communication channels between aircraft and communication and navigation satellites and in channels air-ground communications between aircraft and ground-based complexes (NK) in the range from 2 MHz to 6 GHz.

Currently, a complex of on-board digital communications equipment (CSCS) is used for the exchange of messages between aircraft on-board electronic equipment and ground services [1]. Channels for the exchange of current information are air-to-ground and ground-to-air radio channels of the MB and DKMV ranges. Organization of the exchange of information between ground services and airborne systems is carried out only by the ground complex. The system provides a call for voice communication and data transfer between aircraft and ground services. The ground complex interrogates aircraft located in its service area and collects information necessary for organizing communications from them. Horizontal communication is carried out on DKMV channels with updating of the control information once in 32 seconds according to the ARINC-635 specification [3]. The on-board control unit of the complex is a computer. The interface block of the complex is a separate device.

The disadvantages of this CSCCS include the diversity of the routing and control functions for various devices (control unit and interface unit), which leads to more complicated control algorithms. There is no possibility to reduce the time of message delivery (work in a fixed frame format for the DKMV range according to the ARINC-635 specification, the procedure for getting into communication and acknowledging the exchange strictly according to the TDMA / TDD protocol) and increasing the reliability of high-priority information due to the lack of duplication and mutual complementation for various channels. The presence of a separate modem for the MB band (not integrated into the corresponding transceiver) also complicates the management of the on-board complex. The absence of an antenna matching device in the DKMV range sharply reduces the amount of power given by the power amplifier, and, therefore, radiated to the air, and thereby reduces the communication range.

The technical solutions of the analogue do not allow the simultaneous exchange of information in data networks operating using different exchange protocols, in radio channels with varying degrees of noise and radio interference of natural and artificial origin.

This problem is partially solved in the complex of on-board digital communications, selected as a prototype [2]. However, the use of the prototype still does not allow communication via air-to-space channels between aircraft and communication and navigation satellites. In addition, the proposed structure of the broadband communication module does not provide the necessary level of communication reliability due to the use of a common control bus for channel-forming equipment of the module.

The main technical problem to be solved by the claimed utility model is to expand the complex’s functionality, including increasing the efficiency of the used radio links of various radio bands, implementing navigation definitions based on satellite methods for determining coordinates, identifying moving objects based on a navigation-connected principle through the use of satellite communication module, as well as through the modernization of a broadband communication module operating under the control of the mode I routing and management.

The specified technical result is achieved by the fact that the satellite communication module is additionally introduced into the complex of on-board digital communications equipment, consisting of a three-channel wide-range communication module DKMV and MV / DMV1 ranges, a DMV2 transceiver, a SMV range transceiver, an information protection module, a control and routing module, the control and routing module is connected by two-way communications on the command-information exchange bus and on the high-speed information exchange bus to the on-board hardware and the bus command and information exchange to respective inputs of the above modules and the bus to the high-speed data exchange transceiver BWE band, low-frequency analog and its outputs connected to two-way communication with on-board equipment and the respective inputs of the above transceivers.

A three-channel wide-band communication module, contains two MV / DMV1 power amplifiers, a DKMV power amplifier, an antenna matching device and a digital signal processing unit containing a control device, a DKMV digital pickup exciter and two digital MV / DMV1 pickups, with a high-frequency output the digital exciter of the DCMV range is connected to the input of the power amplifier of the DCMV range, the output of which is connected to an antenna matching device, the output of which is The front is connected by two-way communication with the DKMV range transceiver antenna, the high-frequency outputs of the MV / DMV1 range digital transceivers are connected to the inputs of the MV / DMV1 range power amplifiers, and the corresponding outputs of the control unit of the digital signal processing unit are connected by independent two-sided control buses with the corresponding inputs of the MV / DMV1 power amplifiers range, the input of the power amplifier DCMV range, the input of the antenna matching device, the inputs / outputs of the control unit The digital signal processing are connected to respective two-way communication with the control module and the routing and each of the digital priemovozbuditeley.

The distinguishing features of the utility model are:

- independent control and data transmission in the ShMS module through the use of independent control buses for digital signal processing units (DSP) of the DKMV and MV / DMV1 channels and satellite communications, which allows to quickly supplement and partially duplicate the information transmitted in these channels depending on the interference on the air ;

- use of a satellite communications module that exchanges information and navigation data through satellite communications networks.

KBSSTS is a multichannel device that is designed to receive / transmit information from the on-board electronic equipment of a moving object to the integrated antenna system of a moving object in a wide range of radio waves (2 MHz-6 GHz).

КБСЦС consists of six main modules, namely: control and routing module (МУМ) 1, wide-range communication module (ШМС) 2, forming a channel DKMV range and channels MV / DMV1 range, satellite communication module 3, communication module СМВ range 4, module communication DMV2 range 5, information security module 6. The exchange of information between the modules and the issuance of control commands MUM 1 through the appropriate control buses and specialized buses high-speed data exchange (figure 1). The inputs of the MUM 1 on the control bus and the lines of reception / transmission of analog voice information are connected to the on-board electronic equipment. The MCM 2 is connected to the outputs of the MUM 1 via the first control bus and the second data bus, analogue voice information transmission / reception lines are connected to the DKMV channel and to the MV / DMV1 channels. The structure of the wide-range communication module 2 is shown in Fig.2.

ShMS 2 consists of a DSP 7 unit, a DKMV power amplifier of range 8, an antenna matching device DKMV of range 9, universal blocks MV / DMV1 10-1 and 10-2, a satellite communications module 11, and a switching and separating device 12.

The first and second outputs of MUM 1 are connected by a two-way control and data bus to the control unit of the DSP 7. The information transfer via the bus from MUM 1 to DSP 7 and in the opposite direction is carried out independently. The third, fourth and fifth analog low-frequency lines MUM 1 is connected to the corresponding inputs / outputs of the digital pickup exciter DKMV range and the inputs / outputs of two digital pickup exciters MV / DMV1 range.

The sixth output of MUM 1 is connected by a two-way control and data bus to the satellite communications module 3. The seventh and eighth outputs of MUM 1 are connected by two-way control and data buses to the SMV module 4. The ninth output of MUM 1 is connected by a high-speed data bus to the SMV module of range 4. Tenth output MUM 1 is connected by a two-way control and data bus to the DMV2 module of range 5. The eleventh output of MUM 1 is connected by a two-way control and data bus to the information protection module 6.

The work of the complex is based on principles identical to the general principles of the prototype.

But at the same time, the ShMS 2 module, in which two MV / DMV1 channels and one DKMV channel are implemented, works as follows. After the control information about the corresponding frequency at which information is to be transmitted / received is received on the control unit (CU) 11 of the DSP 7 unit via the control bus, the carrier frequency is synthesized by the digital reception method using digital methods (both for the MV / DMV1 channel, and for the DKMV channel), modulated depending on the operating mode (type of radiation), the data on which are contained in the control information from MUM 1.

UU 11 when operating in data transfer mode (telegraph or telecode) on the data bus and control transmits semantic information to the appropriate exciter. In the channel of the DKMV range, after the digital receiver exciter, the RF signal is fed to the power amplifier unit, and then, through the antenna matching device, to the DKVM antenna. In the channels of the MV / DMV1 range, after the digital exciter excitation, the signal is also fed to the power amplifier unit of the MV / DMV1 range, and then to the corresponding antenna of the MV / DMV1 range. When receiving a signal from the air, the reverse process occurs. Digital receiving exciters carry out the function of modulating / demodulating the signal, through UU 11 they exchange data with the MUM 1 module via the corresponding data bus or exchange voice information directly via analog low-frequency lines (telephone lines).

The satellite communications module 3 exchanges data and navigation information in satellite communications networks, exchanging information with the MUM module 1 via the corresponding data bus. Periodically, the satellite communication module 3 issues MUM 1 data on the monitoring of the condition of the components.

The SMV range 4 module provides a high-speed exchange of audio and video information between moving objects.

Periodically, the module gives MUM 1 data on the monitoring of the status of the components of the SMV module of range 4. The interaction between the radio modem block of module 4 and MUM 1 is carried out, unlike the prototype, via the Ethernet interface.

The DMV2 5 module is designed as a multifunctional integrated terminal [4]. It carries out, through the signal processing and control unit 16, interaction on a high-speed bus with the MUM 1 module and is intended to solve the following functional problems:

- providing noise-immune secure telephone communications and data exchange with mobile objects and ground control points via independent 3 channels with special network exchange protocols [4];

- implementation of navigation definitions based on range-finding methods for determining coordinates;

- identification of subscribers of various virtual networks organized into a radio communication session based on a navigation-connected principle.

The expansion of the functionality of the complex in the field of communications is as follows:

- improving the efficiency of air-to-ground digital radio communication lines by improving the accuracy of object positioning;

-increasing communication reliability through the use of five frequency bands with uncorrelated propagation conditions;

- increase in the volume of received, processed and transmitted data;

- interaction of various protocols of data transmission lines, especially in the presence of interference on the air;

- increase the reliability of the data.

In the field of navigation, the provision of navigation services with high integrity and accuracy is improved, the accuracy and reliability of the positioning of the object is significantly increased.
