Abstract

The utility model relates to radio data exchange systems and can be used for information exchange between moving objects (PO), ground-based complexes (NK) and radars. The main technical problem to be solved by the claimed utility model is to increase the range of stable communication with mobile objects by switching, from a mutually connected command, from on-board and ground computers from the MB radio link to the introduced DKMV radio link in which software and hardware the operations of rigid fastening to each of the moving objects of a set of several working frequencies at which he is allowed to work, adaptive choice of working frequency from the list of allowed, multi-station access to the communication channel with time division in the mode of random and redundant access, data exchange with geographically spaced ground-based complexes, combined using a ground-based data transmission network into a single system.

Description

The utility model relates to data exchange systems and can be used to implement information exchange between moving objects (software) and sources (recipients) of system information through ground-based systems.

Currently, a messaging system between aircraft electronic equipment (Aircraft) and ground services, which are described in documents ARINC-724, is widely used abroad. This system is called ACARS in ARINC documents. It provides a call to voice communication and data transmission [1].

The on-board communications system for operation in the ACARS system, used on domestic aircraft, solves the following functional tasks:

- messaging with the ground complex on the MB (meter) channel in free access and address polling modes;

- messaging with the ground complex on the DKMV (decameter) channel in free access mode;

- processing messages in order to transmit the received information to the crew;

- processing received messages from on-board systems and crew and transmitting this information to the appropriate ground service;

- automated frequency management of an MB range radio station at the command of the ground complex and crew;

- automated control of reception-transmission operating modes of MB and DKMV radio stations.

The on-board ACARS system is interfaced with channel-forming equipment - MB and DKMV radio stations and on-board systems in accordance with ARINC-429.

The on-board control and communication unit is a processor. The main channel for exchanging current information is the MB channel. When flying on routes not equipped with MB communications (hard-to-reach areas, tundra, mountain ranges, and the ocean), communications with aircraft are carried out through the DKMV channel.

The exchange of information between the ground-based civil aviation services and airborne systems is carried out by the ground-based complex, it interviews the aircraft in its service area and collects the necessary information from them. The on-board system in this case operates in the address polling mode. In order for the on-board system to be able to work in the address polling mode, it needs to get service in the ground-based system. For this, the on-board system provides direct access. In addition to these two modes, it is possible to work in telephone mode via a data channel [1, 6].

The disadvantages of the presented messaging system between aircraft avionics and ground services include the impossibility of controlling software located outside the NK radio horizon, which is determined by the boundaries of optical visibility. DKMV channels of existing aircraft are rarely used for flight control due to poor quality of received messages from a single ground complex and the lack of appropriate ground infrastructure. Planning of DKMV communication, as a rule, is carried out on the basis of specialized application software packages, including models of the solar cycle, ionosphere and ionospheric propagation of radio waves, as well as parameters of channel-forming equipment, modems and antennas. Nevertheless, despite the perfection of the programs themselves, communication planning only with their help is ineffective, since instead of constantly changing initial data on the state of the ionosphere in this case, average statistics are used, which can differ greatly from its parameters for a particular day.

Known satellite communication systems with remote moving objects, consisting of ground-based transceiver stations and control stations, constellations of satellites [1, 7]. All these devices contain: transmitters, receivers, one or more antennas, devices for processing transmitted and received signals, automated workstations (AWS) of operators of ground (control) services [2, 3, 5].

However, the cost characteristics of the DKMV radio communication systems allow providing software that is not equipped with satellite communications with a cost-effective data line. Also rising

the reliability of data transmission for objects in the polar regions where the characteristics of satellite channels are degrading.

The closest in purpose and most of the essential features is a radio communication system with moving objects [4], which is taken as a prototype. In this system, while moving, moving objects located within the radio horizon exchange data with the ground-based complex. Messages received by the ground-based complex from the air-ground channel through the data transmission equipment are sent to the PC computer based workstation, where, in accordance with the exchange protocol adopted in the system, the addresses received in the message are identified with the addresses of the moving objects stored in its memory. If the address of the moving object coincides with the address stored in the list, information about the location, motion parameters of the software and the state of its sensors is displayed on the monitor screen of the ground workstation. In the PC-based automated workstation computer, the problem of providing constant radio communication with all N software is solved. When at least one of the software leaves the radio horizon or approaches the border of a stable radio communication zone, one of the software that is assigned by the message relay is determined programmatically. Based on the results of the analysis of the location and motion parameters of the remaining software, the optimal paths for message delivery to the selected moving object remote from the satellite for the radio horizon are determined. The message from the NC through a serial chain consisting of (N-1) software can be delivered to the N-th software. To do this, on the NK in the shaper of the type of relayed messages, the number of the software assigned by the relay and the addresses of the air objects that provide the specified message traffic are laid down in a predetermined category (header) of the transmitted codegram. Messages received on the software are analyzed in a message type analysis unit. After analysis, the issue of sending data via a bi-directional bus to the object’s control system or relaying them to neighboring software is resolved.

In normal mode, when relaying signals from the NK is not required, an address polling of the software is carried out by forming a message for transmission to the radio channel in accordance with the exchange protocol. The message typed by the operator (dispatcher) is displayed on the AWP monitor. After passing through the antenna, radio station, data transmission equipment, the software enters the on-board computer, where identification takes place

the address received in the message with the own address of the moving object. Next, the message is transmitted to the analysis unit of the type of relayed message, where the received header (service part) of the message is decrypted, and it is determined in what mode the software hardware should work. The information part of the message is recorded in the memory of the on-board computer and, if necessary, is displayed on the screen of the data recording unit.

Shapers of the type of relayed messages allow for the exchange of digital data on the channel "operator-pilot" instead of existing voice information. They are designed to select permission / information / request message elements that correspond to the accepted speech phraseology, and to set up arbitrary text. Display of dialed and received messages is carried out on the data recording unit VO and the monitor workstation NK, respectively.

Messages from the outputs of the receivers of signals of global navigation satellite systems GLONASS / GPS are recorded in the memory of ground and airborne computers with reference to global time and are used to calculate the navigation characteristics and motion parameters of each software. Received on the NK navigation messages from all software are processed in the calculator and displayed on the workstation monitor screen.

However, the prototype has the following disadvantages:

- traditional technical solutions used on equipped air routes are completely unsuitable for inaccessible areas, sparsely populated areas with undeveloped ground infrastructure, where there is no continuous MB radio communication field;

- the impossibility of organizing the exchange of data between NK and software located outside the radio horizon of the NK radio station and a chain of (N-1) -th software, which is determined by the boundaries of optical visibility.

Thus, the main technical problem to be solved by the claimed utility model is to increase the range of stable communication with mobile objects by switching, from a mutually coordinated command, from the airborne and ground computers from the MB radio link to the introduced DKMV radio link in which -hardware provides operations of rigid fastening to each of the moving objects of a set of several working frequencies at which he is allowed to work, adaptive select the operating frequency from the list

allowed, multi-station access to the communication channel with temporary separation in the random and redundant access mode, data exchange with geographically dispersed ground-based complexes, combined using a ground-based data transmission network into a single system.

The specified technical result is achieved by the fact that in a radio communication system with moving objects, consisting of a ground-based complex containing a ground-based antenna, a radio station connected by two-way communications via data transmission equipment to the first input / output of the computer of the workstation, the first input of which is connected to the receiver of navigation signals satellite systems, the second input is to the AWP control panel, and the output is to the AWP monitor, a relay type of relay messages connected to the corresponding the input of the workstation computer, N movable objects, each of which includes airborne sensors, a receiver of signals from navigation satellite systems, an analyzer of the type of received messages and an air conditioner of the type of relayed messages, each of which is connected to the corresponding inputs of the onboard computer, the input / output of which is connected to the bidirectional bus of the moving object control system, the on-board computer is connected to the input of the data recording unit and through the on-board device connected in series uru of data transmission, the on-board radio station is connected to the on-board antenna, and data is transmitted from the NK through a chain of serially connected first software, the second software and then to the N-th software, and data is transmitted from the N-th software to the NK in the reverse order, additionally a ground-based data transmission network with system input / output was introduced, connected by two-way communications to each of the M NKs, including each of the (N-1) th territorially deployed NKs, an additional on-board DKMV radio station was introduced at each software, the first and second inputs / outputs of which are connected by two-way connections to the corresponding inputs / outputs of the on-board computer and on-board data transmission equipment, respectively, and the third input / output is connected to the input DKMV on-board antenna, and the DKMV terrestrial radio station, the first and second inputs / outputs of which are connected by two-way communications to the corresponding inputs / outputs of the ground computer and ground data transmission equipment, respectively, and the third input / output is connected to the introduced DKMV ground antenna pazona.

The algorithm of the radio communication system with software 2 consists in exchanging data via the MB radio line until software 2 goes beyond the line of sight with NK 1 or it is not possible to organize data exchange with this software 2 even through a chain consisting of (N -1) th software 2. In this

In this case, a transition is made according to mutually coordinated commands from the airborne and ground computers to the transfer of data from the MB radio communication lines to the entered DKMV radio communication line. In this radio line, to accomplish the purpose of the invention, the software and hardware provide the operations of hard fixing to each of the moving objects a set of several operating frequencies at which it is allowed to work, adaptive selection of the operating frequency from the list of allowed, multi-station access to the communication channel with time division in the mode random and redundant access, data exchange with geographically dispersed ground-based complexes, combined using a land-based data network in a single istemu.

A radio communication system with moving objects operates as follows. During movement, moving objects within the radio horizon exchange navigation and other data on the MB radio link with the ground-based complex 1. Messages received by the ground-based radio station 13 from the air-ground channel through the data transmission apparatus 14 are sent to the ground computer 15 AWP, which can be performed on the basis of a serial PC. In it, in accordance with the exchange protocol adopted in the system, the identification of the address received in the message with the addresses of the moving objects stored in the memory of the calculator 15 AWP is carried out. If the address of the moving object coincides with the address stored in the list, information about the location, motion parameters of the software 2 _i and the state of its sensors are stored in the calculator 15 AWP. Therefore, in the ground computer 15 of the automated workstation, the tasks of ensuring constant radio communication with all N software 2 are solved, and based on information about the exact location of all the software 2 and the parameters of their movement, the operations of storing these messages in the ground computer 15 of the workstation and the necessary data are displayed on the monitor screen 17 of the workstation NK 1 in a form convenient for the perception of the operator (dispatcher).

If at least one of PO 2 is exceeded beyond the radio horizon or when approaching the boundary of a stable radio communication zone, one of the PO 2, which is assigned by the message relay, is determined programmatically. With a constant range change between PO 2 and NK 1, any of N N, the location of which is known and optimal with respect to NK 1 and all others, can be assigned as a repeater for a certain time

ON 2. Based on the analysis of the location and motion parameters of the remaining ON 2, the optimal paths for message delivery are determined for a moving object 2 _N remote from the NK 1 for the radio horizon. The message from NK 1 through a serial chain consisting of (N-1) -th software 2, can be delivered to the N-th software 2 _N. To do this, on NK 1 in the shaper 22 of the type of relayed messages, the number of the software 2 assigned by the relay and the addresses of the moving objects 2 _i providing the specified message traffic are laid down in predetermined bits of the transmitted codogram. Received on the software 2 messages are processed in block 19 analysis of the type of messages. If the message is intended for this software 2, then after analysis, the question of sending data via a bi-directional bus 20 to the control system of software 2, not shown in figure 1, or in relay mode, to transfer them to neighboring software 2 _i, is solved. To avoid collisions, the number of bits in the transmitted message is minimized and data is relayed sequentially in time. When exchanging data on the “operator-pilot” line, especially in the presence of a potentially conflict situation, the crew must fully comply with the commands of the NK 1 operator, who has more information in his area of responsibility. To do this, with the NK 1, the operator sends a corresponding message to the software 2, which is displayed on the screen of the airborne data recording unit 8 in the form of an agreed mark and forms in which, for example, flight number or board number, flight altitude or other characteristics can be displayed. Based on the data received from NC 1 in the on-board computer 5 software 2, together with the ground computer 15, the problem of the presence of dangerous proximity with neighboring software 2 is solved taking into account their predicted positions and possible maneuvers, the time of the next communication sessions with information recipients is determined. Based on the on-board unit 8 of data recording displayed on the screen, the crew of software 2, with the consent of the NK 1 operator, determine the direction of further movement if necessary.

The movement trends of neighboring software 2, if necessary, can be displayed on the screen of their own on-board unit 8 for data recording, and on the monitor screen 17 of the AWP, of all software 2 in the area of NK 1 using the marks marking the previous location of software 2 generated by calculators 5 and 15. By as software moves 2, outdated marks are erased. Loading into memory of the on-board computer 5 necessary data in the form

the system table is carried out during the prelaunch preparation of the moving object 2 through the input / output 4 of the equipment of the ground network 3 data transmission.

When transmitting priority messages for SC 2 from SC 1 in accordance with the categories of urgency adopted in the radio communication system with mobile objects in the shaper 22 of the type of relayed messages, a message blocking code is generated in the message header prohibiting the transmission of other messages for the time allotted for broadcasting data from SC 1 to the selected software 2 _i taking into account the response time of software 2 to the received message and the delay time in the processing paths of discrete signals. Information received at the software 2 _i is displayed on the screen of the airborne data recording unit 8 in the form of alphanumeric characters or in the form of dots and vectors.

The remaining lower priority messages in accordance with the exchange protocol are in the queue of the corresponding category of urgency. In computers 5 and 15, the “aging” time of the information is determined, and if the message has not been transmitted to the communication channel for a certain period of time, then it is “erased” and a request is sent to retransmit the message.

In the normal mode with NK 1, when signal relaying is not required, the address polling of software 2 is carried out by forming a message for transmission to the radio channel in accordance with the exchange protocol. The message dialed by the operator (dispatcher) from the AWP control panel 18 is displayed on the AWP monitor 17 and in parallel after passing the signal to the NK 1 through the calculator 15, data transmission equipment 14, radio station 13, antenna 12, and on software 2 through on-board antenna 11, radio station 10 , the data transmission equipment 9 enters the on-board computer 5, where the identification of the address received in the message with the address of software 2 is performed. Next, the message is transmitted to the analysis unit 19 of the type of relayed message to decrypt the received header (service clock ti) message and a mode determination operation of the equipment software information part 2. Messages stored in memory onboard computer 5 and, if necessary displayed data recording unit 8, which may be embodied as a monitor or other display device.

When using a certain format of the message header from the output of airborne formers 21 of the type of relayed messages, the free access mode can be used from other mobile

objects 2 or a time interval allocation mode for organizing data exchange with a ground complex 1.

As a result of the analysis of the state and load of the radio channels in each NK 1, the number of message collisions is determined, and when this number exceeds the maximum permissible, the system switches to the address polling mode to streamline the operation of the air-ground data channel. In order to avoid collisions in the radio communication channel during the simultaneous transmission of messages by several objects, in the computers 5 and 15 the carrier is monitored when the preamble or the header (the service part of the messages) is exposed to the radio station. A prepared message with software 2 is transmitted only when the radio channel is free. In order to spread in time the moments when mobile objects get in touch at the time when they found that the radio channel is busy, pseudo-random delay of message transmission from mobile objects 2 is formed in computers 5 and 15 - for each software 2 its own.

In the address polling mode, only NK 1 can be a communication initiator. If mobile objects 2 were formed for message transmission and found that the radio channel is free, then they inform the remaining mobile objects about the beginning of the data transfer cycle, including their location, and randomly in the time slots allocated to them distribute the transmitted messages. In each of software 2, the end time of the carrier frequency signal in the radio channel and synchronization pulses are used to calculate the time interval of the own transmission in the calculator 5 and, when it starts, the software sends its own data packet to software 2.

Messages about the location of software 2 and its motion parameters from the outputs of receivers 7 and 16 of the signals of navigation satellite systems, for example, GLONASS / GPS, are recorded in the memory of computers 5 and 15 with reference to global time. The exact synchronization of the slots used for data exchange between subscribers of the system, and their planned use for transmission is known to each user in relation to surrounding users with known coordinates. The distribution of slots by objects is carried out in computers 5 and 15 using the coordinates of the objects. The farther PO 2 is from the aerodrome or from the heavy traffic area of PO 2, the less slots for data transmission are allocated to it. Such

Information allows each NK 1 to organize highly efficient use of the communication channel.

In computers 5 and 15, this data is used to calculate the navigation characteristics and motion parameters of each software. Depending on the selected time interval for the issuance of messages on the NK 1 location 2 software in the calculator 5 at a given time, a corresponding message is generated with reference to the global time for measuring coordinates of the software 2. This time is used in the computer 15 for the known operation of constructing extrapolation marks from software 2 [2, 8]. In the data transmission equipment 9 and 14, well-known operations are carried out: modulation and demodulation, coding and decoding, pairing with nodes 5, 10, 23 - on software 2 and with nodes 15, 13, 26 - on NK 1 and others.

In a situation where one or more software 2 has gone beyond line of sight with NK 1 or it is not possible to organize data exchange with these software 2 even through a chain consisting of (N-1) -th software 2, a transition is made according to mutually linked in time commands from the onboard and ground computers 5 and 15 to transmit data from the MB radio communication line to the introduced DKMV radio communication line, consisting of an onboard radio station 23 DKMV range, an onboard antenna 24 DKMV range, a terrestrial radio station 25 DKMV range, a ground antenna 26 DKMV range. Binding to the time of these commands is carried out with the help of global time stamps received by computers 5 and 15 from the outputs of receivers 7 and 16 of the signals of navigation satellite systems.

To increase the range of stable communication with mobile objects that are outside the line of sight with the NK 1, using the radio data line in the DKMV range in computers 5 and 15 and data transmission equipment 9 and 14, the following known technologies are used [9]:

- standardization of packet data exchange at all levels of the open systems interaction model;

- adaptation of the radio communication system to changing the propagation conditions of radio waves in frequency and spatial diversity;

- automation of procedures for compiling and breaking a communication line with moving objects;

- dynamic frequency control when receiving a more powerful of several radio signals;

- correcting codes and decision feedback methods for receiving messages with compensation for delay, multipath, concentrated on the interference spectrum, Doppler frequency shifts;

- Linking all system subscribers to a single global time;

- adaptation of the radio communication system in terms of data transfer rate, type of modulation and coding.

Thanks to the introduced terrestrial data transmission network 3 for each of the software 2 equipped with a DKMV radio station with the DKMV radio control function, data packets are transmitted (received) through the network of ground complexes 1, simultaneously on several NK 1. In this case, NK 1 is determined on PO 2 , the parameters of the radio signals of which are received most stably, and through it the exchange of data begins. On-board and ground computers 5 and 15 store pre-laid tables with lists of ground systems 1 and sets of frequencies assigned to them. The on-board computer 5 also contains the coordinates of all NK 1. Each NK 1 periodically emits control / synchronization / communication signals at all frequencies assigned to it. To establish a communication line with NK 1, on-board computer 5 software 2 automatically analyzes the received control / synchronization / communication signals from all ground-based complexes 1 at all frequencies and selects the best frequencies (for example, signal-to-noise ratio or received signal power) and ground complexes 1 due to the implementation of the well-known principle of adaptation in frequency and space. According to the measured signal-to-noise ratio, in the on-board computer 5 software 2 selects the data transfer speed, as well as the type of modulation and coding. Evaluation of the signal-to-noise ratio is carried out by all NK 1 and PO 2 each time a message is received or a control / synchronization / communication signal. This value is reported to the opposite side as a recommended data rate. In the APD 9 and 14, when operating on a DKMV radio station, well-known algorithms can be used, for example, high-speed adaptive modems designed to operate in multipath channels. To increase the reliability of information reception, a noise-resistant code, for example, cyclic, can be used.

Thus, each of PO 2 can communicate at several operating frequencies, known to all participants in the movement. Depending on the importance of software 2, their number can vary from 2-3 to 6-8. The lists of allocated frequencies change depending on the time of the year, taking into account seasonal ionospheric changes. Transport systems associated with the transportation of passengers and strategic cargoes are the most important, therefore, they are assigned a greater number of operating frequencies. When moving, PO 2 gets in touch, choosing that NK 1 for communication, the conditions for the propagation of radio waves for which at this time are optimal . Moreover, it is not at all necessary that the selected NK 1 was the closest. The communication channel thus constructed between software 2 and the recipient (source) of information, as a rule, will include a communication channel of the DKMV band and a terrestrial data transmission network 3. Using the on-board computer 5 software 2 and the ground computer 15, the optimal operating frequency will be constantly selected based on the ionosphere models and radio wave propagation according to hardware measurements of the expected communication quality and analysis of messages from ground correspondents. This ensures an increase in the range of data exchange with PO 2 located at distances from NK 1 from several hundred to several thousand kilometers.

In order to increase the communication range with a given stability and reliability, in addition to changing the operating frequency range, increasing the transmitter power of radio stations 23 and 26 and reducing the noise level of their receivers, the system uses known methods of frequency diversity, spatial diversity, time diversity, multipath diversity, adaptive equalization, coding with direct error correction, interleaving to combat the effects of multipath, fading, impulse noise. The range and reliability of communication is determined by the properties of the ionosphere over the area of communication, its correlation characteristics in space, frequency and time. The less correlated the diversity paths, the higher the reliability of communication. The radius of spatial correlation in the quasi-regular parameters of the ionosphere (signal energy, multipath) is usually 300-600 km. Therefore, NK 1 are distributed in space at a distance exceeding this value. Of all the NK 1 spaced in space, one leader is assigned, who, in addition to the operations discussed above, performs the function of controlling the processes occurring in the system. TO

the control functions of the master NK 1 are supplemented by operations to control the frequency, status table of registration software 2, system table, configuration, quality of data transfer, alarm processing, remote diagnostics. Through the input / output 4 of the terrestrial data transmission network 3, an interface is provided with the system information sources (receivers) located on the ground and the on-board computers 5 software are programmed 2. The operation of the terrestrial data transmission network 3 is carried out on the basis of the use of a single global universal coordinated time by all subscribers (UTC) received from existing facilities of the global navigation satellite system.

For the interaction of ground-based complexes 1, end users and software 2, a ground-based data network 3 is used. It can be implemented in various known ways, for example, during the interworking of NK 1 through packet switching centers in accordance with the X.25 protocol [1, 6]. Connections between NK 1 and X.25 packet switching centers (routers) can be provided through specially allocated or leased communication channels. They will allow broadcasting the message addressed by the user to a specific software 2 to the ground complex 1 where this software 2 is “registered” and where optimal reception conditions are provided at a given time. The radio communication system with software 2 operates in automatic mode without operator intervention at the selected frequencies from the list of frequencies assigned during communication planning.

When transmitting data over a DKMV line, for example, short packets (of the order of 200 bytes of information) of messages lasting less than 2.2 seconds in a given time slot of 2.5 seconds in duration are used in accordance with the well-known multi-access protocol with time division and reservation of slots [9]. This ensures the prevention of mutual interference between transmissions from ground-based systems 1 and from many software 2 in the same slot. In the process of communicating, data is exchanged between airborne and ground computers 5 and 15 through the corresponding nodes: 9, 10, 11, 23, 24-on software 2 and 14, 13, 12, 26, 25-on NK 1.

At the time of application submission, functioning algorithms and corresponding software of the claimed radio communication system have been developed. Nodes 1-22 are the same as the prototype. Input nodes 23 and 26 can be performed at the radio stations Yagut-K DKMV. Calculators 5 and 15 can be

performed, for example, on a processor board 5066-586-133MHz-1 MB, 2 MB Flash CPU Card manufactured by Octagon Systems and computers of the Baguette-01-07 type YuKSU.466225.001, respectively. Typical aircraft keel slot antennas of the “Slit” type can be used as antennas of the DKMV range for software, and a half-wave vibrator for the NK type antennas.

Recording data on the location of a moving object selected for data exchange, its motion parameters and software crew intentions in ground computers 15, working simultaneously with several NK 1s in the DKMV range allows increasing the range of stable communication with moving objects due to the transition by a mutually connected command from the onboard and ground-based computers with MB radio links to the entered radio link in the DKMV range and provide:

- data exchange between various recipients of information and mobile objects located outside the radio horizon: sea and river vessels, cars, civilian aircraft, trains, small aircraft and state aviation;

- data exchange via the “last connection” due to storage in the main NK 1 and in ground complexes, with the help of which the last communication session for the corresponding software 2 was organized. In this case, recording in ground calculators 15 data about the location of the software, its motion parameters and intentions with reference to the unified global time, it will be possible to calculate the extrapolation coordinates of the selected software at a given point in time;

- the specified requirements for the reliability of communication with the software and the continuity of the service based on routing in the ground network 3 data transmission;

- work simultaneously with several NK 1 in the DKMV range, equivalent to the operation of ionospheric monitoring to select the optimal operating frequency [6, 9].

A network of NK 1 spaced in space, interconnected using a ground-based data network 3, allows for overlapping of the Eurasian and oceanic spaces with high system reliability and throughput.
