Description

The invention relates to centralized radio security systems and can be used to combat theft of vehicles (TS).

Known radio-channel alarm system for centralized protection of vehicles, real estate, people and animals according to patent RU No. 2182088, 60 R 25/00, which contains installed on the vehicle blocks of security detectors associated with the object terminal devices having antennas for radio communication as well as a data collection and processing center having a remote terminal device with an antenna of a remote terminal device for radio communication and a central monitoring station (CMS), which includes a connected an information input adapter board connected to the remote terminal device, an information processing processor, a processing and display unit of cartographic and semantic information, and a printer with a printer adapter, the input of which is connected to an information processing processor configured to connect to the processing and display unit, with each other cartographic and semantic information and with the ability to output information to the printer adapter. At the same time, the monitoring station is capable of automatically monitoring the operability of the radio channel by tracking the periodic receipt of notifications from each object terminal device, the radio communication is made in the form of a microcellular data network (ISMT) containing base stations and repeaters installed on the ground, configured to receive code messages from object terminal devices, selection and relaying of these messages to the nearest base station or relay.

The disadvantages of this radio channel system are the high cost and complexity of installing a large number of radiating electronic equipment (RES) on the terrain and objects of urban infrastructure.

This is due to the fact that the frequency resource allocated for civilian use is very limited and for the deployment of the MRTD it is necessary to obtain the appropriate permits from the Ministry of Communications of Russia. Moreover, with the increase in the number of ground-based base and relay stations required for continuous coverage of the territory, it is becoming increasingly difficult to fulfill the conditions of electromagnetic compatibility with other RES. A serious problem, especially for such large cities as Moscow and St. Petersburg, is the allocation of land for these stations.

These disadvantages are inherent, although to a lesser extent, and the radio channel system according to patent RU No. 2198800, 60 R 25/00, 60 R 25/10, G 08 C 13/00, commercially available by the applicant company under the trademark CarNet ( Catalog "Radio communication systems", LLC "Altonika", 2003/2004).

The specified system contains security alarm installations located on protected vehicles that are capable of determining the status of protected vehicles and changes in these states, generating and transmitting notifications about the status of protected vehicles and notifications of changes in these states via MRTD and standard cellular mobile network, for example, GSM -networks, as well as geographically distributed relay nodes of the ISMT configured to receive notifications from security alarm installations, select these notifications and ret their broadcasting via radio and / or wired communication channels, as well as a data collection and processing center containing a handheld terminal device connected via a central radio modem to a standard cellular mobile communications network, and a monitoring station including an information input adapter configured to receive messages from the telephone network, and an information processing processor connected to it, the outputs of which are connected respectively to the processing and display unit of cartographic and semantic information and to the printer.

The disadvantage of this radio channel system is its low noise immunity due to the use of a low power signal (up to 5 mW) with a known deterministic structure. Supplementing the ISMT with a standard cellular mobile network, such as a GSM network, to reduce the capital costs of creating a specialized network of repeaters and base stations does not eliminate this drawback, since standard cellular networks are also very vulnerable to intentional (intentional) interference that can be applied attacker.

The possibility of applying such interference became a reality after small-sized jammers - directors of intentional interference to standard cellular mobile networks, entered the commercial market. So, according to the advertising information of the Israeli company NetLine, the C-Guard LP jammer mass-produced by this company is capable of blocking cellular communications for almost all currently used standards. With an average radiation power of (5-50) mW and a mass of not more than 0.6 kg, this jammer provides effective blocking of subscriber terminals of standard cellular mobile networks in a radius of (5-80) m around itself.

An example of the use in practice of means of jamming a GSM channel during vehicle theft is given, for example, in the magazine "Master 12 Volts", August-September 2004, p. 82.

To increase the coverage area and increase the noise immunity of the above system, in patent RU No. 2231458, 60 R 25/00, G 08 B 25/10 it is proposed to use two innovations: air carriers - tethered balloons or airships - for installing base stations on them and a narrow-band signal with "jumping" carrier frequencies - the so-called hopping signal (patent RU No. 2228275, 60 R 25/10, G 08 B 25/10, G 08 V 29/16), protected by the trademark "HOPPING" (certificate No. 264485 dated 01.03.04 in the name of the applicant company). The pay for the simultaneous expansion of the system coverage area and increase of its noise immunity is a certain complication and, accordingly, a rise in the cost of the receiving part of the equipment, in which rather fine (based on the fast Fourier transform) signal processing is carried out. However, given that the number of hopping signal receivers in the system is incommensurably less than the number of hopping signal transmitters, the contribution of this increase in the cost of receivers to the cost of the entire system is small.

The specified radio channel system for collecting and processing information for centralized security is selected as a prototype of the claimed technical solution.

It contains alarm settings, each of which includes a block of security detectors, the outputs of which are connected to the inputs of the object terminal device configured to use a radio channel, anti-theft system control unit connected to each other, the inputs of which are connected to the outputs of the block of security detectors, and a radio modem connected to a standard network of a fixed or mobile land radio service, a data collection and processing center containing a remote terminal device о, connected via a central radio modem to a standard network of fixed or mobile land radio service, a monitoring station, containing an information processing unit connected to each other, the output of which is connected to the input of the secondary processing, display and registration unit of cartographic and semantic information associated with one or more points centralized security, connected to the telephone network, and an information input adapter connected to the remote terminal device and connected through the telephone network to outputs of telephone object terminal devices, as well as base stations, configured to receive code messages from security alarm installations, select these messages and transmit them over the air and / or telephone network to a data collection and processing center, while object terminal devices of security installations the alarms are made with hopping-signal transmitters, a hopping-signal receiver is introduced into the information collection and processing center, the output of which is connected to the remote terminal device, and b The base station is made in the form of a hopping signal repeater, the onboard part of the hopping signal repeater is mounted on a tethered balloon filled with gas, whose density is lower than air density, and connected with a ground cable and a cable winch to the ground part of the hopping relay signals, the onboard part of the hopping signal repeater contains a block of flight parameters sensors, as well as a hopping signal receiver, the output of which is connected to the input of the analysis unit, the outputs of which are connected to the inputs of the radio channel about the terminal device of the hopping signal repeater, the ground part of the hopping signal repeater contains a power supply, control and management unit for flight parameters, the first input of which is connected to the central security console, the first output to the control input of the winch for the cable cable, and the second output to the first input of the hopping-signal repeater telephone terminal device, configured to receive messages on the second input via cable cable from the analysis unit and to transmit data via the telephone network to an information input adapter, while the output of the flight parameters sensor block is connected to the second input of the power supply, flight control and control unit using a cable cable, configured to supply electric power through it from the power supply unit, flight parameters control and flight control to the onboard part of the repeater hopping signals.

The accuracy of determining the current location of the vehicle is required to intercept the hijacked vehicles (TCBs) by rapid response forces by incorporating a high-precision GPS receiver into its on-board equipment, which receives and processes signals from the global satellite radio navigation system (for example, patents RU No. 2225302, 60 R 25 / 00, G 08 B 25/08, RU No. 2228542, G 08 G 1/123, B 60 R 25/00, etc.).

However, such a technical solution has its drawbacks. The fact is that to ensure acceptable accuracy of determining the location of the TCB, the GPS receiver should always be in the zone of reliable reception of global satellite navigation signals from several (at least four) satellites at the same time, which is difficult to do in urban conditions. First, shading affects satellite signal paths, especially in high-rise areas. Secondly, hijackers can use deliberate interference with the reception of signals by the GPS receiver (jamming the GPS receiver).

The subject of the present invention is a system for searching and intercepting a fusion system, comprising a security alarm installation located on board the fusion system capable of receiving signals from a global satellite radio navigation system and determining the current location of the fusion system, as well as with the possibility of emitting and receiving signals from a standard cellular mobile network and radiation signals with a jumping carrier frequency - hopping signals containing code messages about the identification signs of this TCB and its current location airborne subsystems distributed within the controlled territory, each of which consists of a cable of an airborne surveillance system connected to each other via a cable-cable located on board an aerostat carrier and including a hopping signal transmitter emitted by burglar alarm installations and a flight control unit parameters with sensors connected to it, as well as a ground-based complex with a winch for a cable cable, which provides power supply to the balloon and reception with the board of the balloon carrier of flight control signals, a data collection and processing center configured to receive hopping signals relayed by the balloon, select and process code messages and display the results of this processing in the form of TCB marks moving against the background of the road map , measuring the current location of the TCB, generating and transmitting to central security points code messages about identification signs and the current location of the TCB at personal-road network for the formation of target designations for the quick reaction forces, as well as with the possibility of transmitting over the air or wire communication channels to the ground-based complexes of aerostatic subsystems of commands to control the flight parameters of the aerostat carrier, while a video camera with a stabilization mechanism has been added to the airborne observation complex orientation control, a video camera control unit and series-connected video image compression unit, the input of which is connected to the output of the video camera, and transmitted video image transmitter configured to transmit radio-compressed airborne information to the data collection and processing center of the compressed video images, while the video camera control unit is connected to the stabilization and orientation control mechanism and the video camera, and its output is connected to the flight parameters control unit, when this center for the collection and processing of information is made with the possibility of geometric and amplitude transformations of these video images and combining them with the corresponding fragments ntami schematic maps of the road network, as well as the ability to search, detection and identification of the TCB corresponding to the received coded messages, clarify the location of the CF on the elements of the road network and correct the data transmitted to the central security points.

Particular features of the invention are as follows.

The security alarm installation comprises a security detector unit, a microcontroller, a GPS receiver configured to receive and process signals from global satellite-based radio navigation systems, a first transceiver module configured to receive and transmit messages over a standard cellular mobile communications network, and an object terminal device made with the possibility of emission of hopping signals, the input of which is connected to the output of the microcontroller, and the output is the antenna output of the alarm system, rednaznachennym radiation hopping-signals, wherein the microcontroller is connected to a first transceiving module, the input of the microcontroller is connected to the GPS-receiver output, and is connected to the multichannel input multiple-output block intrusion detectors.

The information collection and processing center comprises a hopping signal receiver, a second transceiver module configured to receive and transmit messages over a standard mobile cellular network, a remote terminal device, a video image receiver, a video image conversion unit, a secondary processing and display unit for cartographic, semantic and video information and a centralized monitoring console comprising serially connected information input adapter and a primary information processing unit, output to is connected to the first input of the secondary processing and display unit of cartographic, semantic and video information, the output of which is connected to the first input of the console terminal device and configured to connect to a geographically distributed network of central security points, while the output of the hopping signal receiver is connected to the second input of the console terminal device, which is configured to transmit messages to the terminal devices of ground-based complexes of geographically distributed aerostat subsystems, and is connected with the second transceiver module, and the first and second outputs of the console terminal device are connected respectively to the second input of the secondary processing and display unit of cartographic, semantic and video information and to the input of the data input adapter included in the central monitoring console, and the receiver output video images through the video image conversion unit is connected to the video input of the secondary processing and display unit cartographic, semantic and video information.

The ground-based complex contains a terminal device and a power supply and flight control unit connected to each other, configured to send commands to the winch and to supply power via a cable cable to an airborne surveillance system located on board the balloon, the terminal device is configured to receive the first input of messages from the center for collecting and processing information, and the second input and output of the terminal device are connected via a cable cable, respectively, to the output of the control unit flight parameters and to the input of the camcorder control unit.

The objective of the present invention is to provide a system for searching and intercepting a fusion, providing more effective than the prototype system, the interception of fusion.

The technical result provided is to increase the accuracy of determining the location of the TCB in the face of violations of the stable reception of signals from the global satellite radio navigation system caused by the influence of high-rise buildings and / or the use of deliberate hijackers by hijackers. This result is achieved by introducing into the composition of the airborne surveillance system installed on board the balloon carrier, a surveillance camera and using video images of the TCB and adjacent sections of the road network received from the balloon carrier to “tie” the TC mark to the map-scheme of the controlled city territory. This allows for acceptable accuracy in determining the location of the TCB relative to the elements of the road network (houses, intersections, and other reference points), even in the case of jamming of the GPS receiver by intruders when the TCB moves along the road network.

. Information about this site is also given in the patent descriptions RU No. 2216463, 60 R 25/00, 60 R 25/10, G 08 C 13/00; RU No. 2220859, B 60 R 25/00, B 60 R 25/10, G 08 C 13/00; RU No. 2228860, 60 R 25/00, G 08 C 25/10. The format of the data transmitted by the object terminal device 5 based on the hopping-signal transmitter "RIF STRING RS-202TP" is set by software. The range of its action is, depending on the conditions of propagation of radio waves, from 5 to 10 km.

To transmit notifications in the system under consideration, as in the prototype system, a standard mobile cellular network is used, for example, the GSM standard, the terminals of which are the first transceiver module 4 installed on the TCB and the second transceiver module 14 located in the data collection and processing center 11. They can be performed, for example, on the basis of the GSM module TS35 Terminal of Siemens. In the REEF GSM-2000 terminal mobile cellular communications equipment commercially available by the applicant company (certificate of conformity No. РОСС RU.ME30.B.01155), this GSM module is docked with microcontroller 3 and allows transmission via a GSM network to a second transceiver module 14 code messages generated by the microcontroller 3, in accordance with the information received from the block 2 security detectors. In the opposite direction, from the information collection and processing center 11, in which the second transceiver module 14 is installed, commands for controlling the microcontroller 3, in particular, commands ensuring blocking the movement of the TCB, can be transmitted via the GSM network.

The GPS receiver 6, connected to the microcontroller 3, is present in another model of terminal equipment of the cellular mobile communications network "REEF GSM-3000", also commercially available by the applicant company (certificate of conformity No. РОСС RU.ME30.B.01155). This technical solution allows autonomously on board the TCB to measure its current coordinates and transmit them to the center 11 for collecting and processing information as part of a code message — via a GSM network or, through an object terminal device 5 — through one of the hopping 8 relay 8.

As the monitoring station 16, which is one of the key elements of the information collection and processing center 11, the “RS-200P” (or “RS-202P”) block can be used. These blocks are commercially available by the applicant company (for example, the catalog "Radio-channel security systems", 000 "Altonika", 2003) and are intended for use in centralized radio security systems of various real estate objects (trade pavilions, warehouses, garages, summer residences, etc.) .

The monitoring station 16 contains a block 17 for the primary processing of information (based on a digital processor), the output of which is connected to a block 18 for the secondary processing and display of cartographic, semantic and video information, as well as a standard adapter 15 for inputting information designed to provide communication with the remote terminal 13.

When implementing the center 11 for collecting and processing information, as another key element of it, block 18 for secondary processing and display of cartographic, semantic and video information, the Geobilder® software and hardware complex that is commercially available from the PC Geokibernetika company (certificate of conformity) can be used No.ROSS RU.KP02.C00014).

The Geobilder hardware-software complex is an automated workplace of the operator with developed software that implements the technology of geographic information system (GIS technology), which allows you to combine and display vector cartographic, semantic and raster video information on one screen. The description and principles of functioning of the Geobilder software and hardware complex are presented in the advertising material GeoBuilder Software Complex, 2002 and on the manufacturer’s website

Воздушный комплекс 9 наблюдения установлен на борту привязного аэростатного носителя 10, заполненного газом, плотность которого ниже плотности воздуха, и связан с помощью кабеля-троса 26 с наземным комплексом 22.The balloon subsystem 7, consisting of an airborne surveillance system 9 and a ground-based complex 22 with a winch 22 'and a cable-cable 26, is produced by the AVGUR aeronautical center

The airborne observation system 9 is installed on board a tethered balloon carrier 10 filled with gas, whose density is lower than air density, and connected via cable 26 to the ground system 22.

Она содержит установленные на борту беспилотного летательного аппарата блок контроля полетных параметров, видеокамеру с механизмом стабилизации и управления ориентацией и блоком управления видеокамерой, последовательно соединенные блок компрессии видеоизображений и передатчик видеоизображений, а также установленные в центре сбора и обработки информации приемник видеоизображений, который через блок преобразования видеоизображений подключен к блоку вторичной обработки и отображения картографической, семантической и видеоинформации. Требуемое качество передаваемого видеоизображения при ограниченной пропускной способности радиоканала обеспечивается, например, с помощью JPEG-преобразования, достаточно полно описанного, например, в книге Дж.Миано "Форматы и алгоритмы сжатия изображений в действии", "Триумф", Москва, 2003.With the exception of the hopping 8 relay, the rest of the onboard equipment of the balloon subsystem 7, shown in Fig. 4, is part of the video surveillance system currently developed by the Avgur aeronautical center for traffic control in Moscow (message in the newspaper Okrug. Severo -West ". 12/13/2003). The balloon subsystem 7 itself is similar to the airborne video surveillance and data processing equipment of the complex with the Pchela 1 remotely piloted aircraft, commercially available from the Kulon Research Institute, Moscow (for example, Rosoboronexport advertising materials

It contains a flight parameters control unit installed on board an unmanned aerial vehicle, a video camera with a stabilization and orientation control mechanism and a video camera control unit, a video image compression unit and a video image transmitter connected in series, as well as a video image receiver installed in the data collection and processing center, which through a conversion unit of video images is connected to the secondary processing and display unit of cartographic, semantic and video information tion. The required quality of the transmitted video image with limited bandwidth of the radio channel is provided, for example, using JPEG conversion, which is described quite fully, for example, in the book by J. Miano “Formats and algorithms for compressing images in action”, “Triumph”, Moscow, 2003.

The 8 hopping-signal repeater proposed for installation on board the balloon carrier 10 was implemented by the applicant enterprise as part of the R&D Carnet-3 and passed field tests in the Moscow region in 2003. The principles of its construction are described in detail in patents for inventions RU No. 2228860, B 60 R 25/00, G 08 B 25/10, RU No. 2228861, 60 R 25/00, G 08 B 25/08, previously obtained by the applicant company.

Other blocks and nodes used in the system under consideration are standard products of electronic computing equipment used in mass-produced RES.

In accordance with the foregoing, the possibility of practical implementation of the claimed technical solution is not in doubt.

The system under consideration for the search and interception of TCB (figures 1 and 2) works as follows.

When the vehicle is stolen, the security alarm installation 1 located on its board (Fig. 3) triggers one or more sensors (volume, movement, etc.) that are part of the security detectors unit 2, and alarm notifications are generated. From the corresponding channels (loops) of the multi-channel output of the block 2 security detectors, these alarm notifications are received in the corresponding channels of the multi-channel input of the microcontroller 3.

The microcontroller 3 generates the corresponding alarm message, which contains the identification signs of this TCB (for example, brand, state number, color, name of the owner, etc.), and the sensor number in block 2 of the security detectors, the operation of which led to the appearance of an alarm notification. The microcontroller 3 transmits the specified alarm message to the first transceiver module 4, which emits a standard high-frequency signal of a cellular mobile network (for example, a GSM signal) that carries the specified alarm message. At the same time, the microcontroller 3 transmits the same indicated alarm message to the object terminal device 5, which generates and broadcasts alarm signals with jumping carrier frequencies - alarm hopping signals (that is, hopping signals carrying the specified alarm message).

Features of the hopping signal (patent RU No. 2231458, 60 R 25/00, G 08 25/10/10) determine its high noise immunity at a sufficiently low (up to 5 mW) radiation power. This was confirmed by field tests using hopping signals conducted by the applicant enterprise in the framework of R&D-Carnet 3. However, the formation, radiation, relay and processing of hopping signals are not relevant to the subject of this patent and therefore are not considered further.

At those times when the TCB is in the area of stable reception of signals from the global satellite-borne radio navigation system, the current location of the TCB is determined directly on board using the GPS receiver 6. The coordinates of the TCB measured by the GPS receiver 6 are transmitted to the microcontroller 3, which includes them as part of the alarm Messages using the appropriate protocol. The indicated alarm messages containing the coordinates of the TCB are transmitted further in two ways:

- through the object terminal device 5 - in the form of an alarm hopping signal - to the hopping signal relay 8 included in the aerostat subsystem 7;

- through the first transceiver module 4 - into the GSM network.

Carrying an alarm message, the alarm hopping signal emitted by the object terminal device 5 is received by one or more hopping signal repeaters 8 (Fig. 4), which are part of the airborne surveillance systems 9 installed on board the balloon carriers 10.

The relay 8 hopping signals receives an alarm hopping signal emitted from the TCB, supplements with service information about the relay (to prohibit retransmission) and transmits it to the center 11 of the collection and processing of information. In the center 11 for collecting and processing information (Fig. 5), a relayed hopping alarm signal is received by a hopping signal receiver 12, compared with signals received from other hopping signal repeaters 8, and, when differences are detected, is fed to one of the inputs of the remote terminal devices 13.

If the TCB is in the range of a standard cellular mobile network, then at the same time a standard high-frequency signal emitted by the first transceiver module 4 and carrying an alarm message is fed to the input of the second transceiver module 14 and is fed from it to the corresponding input of the remote terminal 13.

Thus, from one TCB to the remote terminal device 13, up to two of the same type of alarm messages can be received. If there are two of the same type of alarm messages, the remote terminal 13 ignores one of these alarm messages. Further, in the remote terminal 13, the alarm message received from the hopping receiver 12 or from the second transceiver module 14 is selected and converted into a standard format perceived by the information input adapter 15, which is a part of the monitoring station 16. Through the information input adapter 15, this alarm the message enters the block 17 of the primary processing of information, is digitally processed and fed to the block 18 of the secondary processing and display of cartographic, semantic and video information. In the block 18 of the secondary processing and display of cartographic, semantic and video information, this information is additionally processed with the participation of a human operator in accordance with the GIS technology and displayed on the monitor screen. The result of this processing step is the identification of the TCB, that is, the presentation on the monitor screen in a convenient form for the operator of the TC mark against the background of a fragment of a map of the served area accompanied by identification text information (for example, color, state number and mark of the TCB, information about its owner and etc.). The results of this processing, hereinafter referred to as target designations, are transmitted to the network of points 19 of the centralized security.

After identifying the TCB, the operator of the information collection and processing center 11 visually evaluates the cartographic, semantic and video information presented on the screen of the monitor and makes a decision on further actions. In particular, he can use the block 18 of secondary processing and display of cartographic, semantic and video information to send a corresponding command to the remote terminal device 13. At this command, the remote terminal device 13 through the second transceiver module 14 sends a command to mute the TCB engine via the GSM network. The block 18 of the secondary processing and display of cartographic, semantic and video information is notified of the delivery of such a command by filing notices to central security points 19. The tactics of intercepting the TCB by the rapid reaction forces should now be based on the fact that a command has already been issued to jam the engine of the TCB.

On a GSM network, the command to kill the TCB engine is received in the security alarm installation 1 (Fig. 3) on the TCB by the first transceiver module 4 and then transferred to the microcontroller 3, which generates the corresponding command to the TCB executive bodies.

The specifics of information processing in the system under consideration, in comparison with the prototype system, is the use, in conjunction with cartographic and semantic information, of raster video images received by the video camera 20 from the side of the balloon 10.

The process of obtaining and using raster video images in conjunction with semantic and cartographic information in a single technological process is as follows.

After identifying the TCB, the operator of the information collection and processing center 11 sends target designation from the output of the secondary processing and display unit 18 of the cartographic, semantic and video information to the remote terminal device 13. From it, it enters the terminal devices 21 of the ground-based systems 22 of the aerostat subsystem 7.

At the same time, a number of necessary flight parameters are measured using sensors included in the onboard balloon carrier 10 of the airborne observation system 9. These may include, for example, the lift height of the balloon 10 above the ground, the speed of horizontal drift caused by wind loads and other parameters. In this case, the height of the balloon balloon 10 above the ground is adjusted using the hoist 22 'installed in the ground complex 22.

Using the stabilization and orientation control mechanism 23, the angular orientation parameters of the video camera 20 are measured in space, which are transmitted to the video camera control unit 24. The values of the flight parameters measured by the sensors and the parameters of the angular orientation via the flight parameter control unit 25 are transmitted via cable 26 to the ground complex 22 (to the terminal device 21).

In the terminal device 21, angular corrections are calculated for the position of the video camera 20, necessary so that the TCB, moving along the road network, is always in the middle of the field of view of the video camera 20. To calculate the angular corrections, we use:

- the values of the current coordinates of the TCB, coming from the center 11 of the collection and processing of information;

- pre-known geographical coordinates of the surface complex 22;

- flight parameters transmitted from the balloon 10;

- the angular orientation parameters of the video camera 20 transmitted from the balloon carrier 10 in three-dimensional space, measured using the stabilization and orientation control mechanism 23.

The values of the angular corrections calculated in the terminal device 21 are transmitted via cable 26 to the balloon 10, to the video camera control unit 24. Using these angular corrections in the camera control unit 24, the control actions for the stabilization and orientation control mechanism 23 necessary to correctly orient the camera 20 are calculated.

After the video camera 20 has taken the required position, the video frames of the earth's surface obtained using it, containing the image of the TCB and adjacent sections of the road network, are transmitted to the video compression unit 27.

обеспечивает организацию доступа к любым типам информации через систему независимых драйверов, осуществляет развязку графического ядра и пользовательского интерфейса с системой хранения и управления данными. Это позволяет интегрировать в единой среде информацию от различных источников. Любой источник, поддерживаемый Geobuilder, фактически является или может рассматриваться как база данных. Это - растровые слои видеоизображений, векторные и семантические данные, математические модели, подключенные через систему драйверов.After compression, for example, using JPEG conversion in the video compression unit 27, the compressed video image is transmitted to the video image transmitter 28, transferred to a high-frequency carrier, and broadcast over the air to the information collection and processing center 11. Here it is received by the video image receiver 29 and, after preliminary amplitude and geometric correction in the video image conversion unit 30, is supplied to the secondary processing and display unit 18 of cartographic, semantic and video information. Further, the specified video image is processed in accordance with the GIS technology. In particular, the aforementioned software and hardware complex Geobuilder

provides access to any type of information through a system of independent drivers, decouples the graphics core and user interface with a data storage and management system. This allows you to integrate information from various sources in a single environment. Any source maintained by Geobuilder is, in fact, or can be considered a database. These are raster layers of video images, vector and semantic data, mathematical models connected via a driver system.

Thus, on the monitor screen of the block 18 of secondary processing and display of cartographic, semantic and video information, a section of the street-road network is displayed with the coordinate mark of the TCB corresponding to the coordinates determined by the GPS receiver 6 and transmitted as part of an alarm message received at the collection and processing center 11 information. The coordinate mark of the TCB is accompanied by textual information with the identification features of the TCB, isolated from the same alarm message. In addition, those vehicles moving along the road network that are in the field of view of the corresponding video camera 20 are displayed on the monitor screen. Based on the identification signs of the vehicle, the operator determines which vehicle moving along the road network is the vehicle from which An alarm message was sent. If the attackers did not change the identification features (for example, the state number and color of the vehicle), then identifying the TCB with a certain mark of the vehicle moving along the road network requires only one alarm message. When changing the state number or color of the TCB, accurate identification of the TCB requires the receipt of three or four alarm messages.

The identification of the TCB with a specific moving object allows the operator to use all the advantages of a database management system when setting up and working with the secondary processing and display unit 18 of cartographic, semantic and video information. In particular, in the case under consideration, reliable marking of the TCB mark against the background of noise, its stable tracking and linking to the road network with the possibility of determining the location relative to the identified landmarks are provided. From the output of the secondary processing unit 18 and the display of cartographic, semantic and video information, information about the identification features and the current location of the TCB is sent to central security points 19. The procedures for the subsequent use of this target designation in paragraphs 19 of the centralized guard to intercept the TCB by the quick reaction forces are not the subject of this application and are not considered further.

Power is supplied to the balloon 10 from the power supply and flight parameter control unit 31. From the same block, commands are received to the winch 22 ', which allow, for example, to reduce the length of the cable cable 26 and, accordingly, the flight altitude of the balloon carrier 10 - in case of unacceptably large wind loads on the balloon balloon 10. These commands are generated in the terminal device 21 in in accordance with the signals from the sensors coming from the block 25 control flight parameters.

When the TCB moves along the street-road network, the process of measuring its current coordinates using the GPS receiver 6 may be interrupted periodically due to shadowing by tall houses and trees, or in the case when intruders deliberately interfered with global satellite radio navigation systems. In the prototype system, the TCB mark will disappear from the monitor screen, and, accordingly, the operator of the information collection and processing center 11 will be deprived of the opportunity to accompany the TCB and issue target designations to central security points 19.

In the system under consideration, this will not happen, due to the fact that the TCB is defined as a specific moving object, and the support of the TCB is carried out using a video camera 20, the orientation of which in space changes in accordance with the change in location of the accompanied TCB. Information about these changes is contained in the sequence of target designations sent from the information collection and processing center 11 to the terminal device 21, which generates the corresponding corrective commands for controlling the orientation of the video camera 20. These cables are sent to the video camera control unit 24 by cable 26 and are processed by the mechanism 23 stabilizing and controlling the orientation of the video camera 20. Optionally, optical control commands can be sent to the video camera control unit 24 from the terminal device 21 via the same cable cable 26 eskimi parameters video camera 20, such as lens focal length, aperture, wide field angle and other parameters. These commands are converted in the camcorder control unit 24 to the corresponding control actions that are supplied to the executive bodies of the camcorder 20. The measured values of the optical parameters of the camcorder 20 are transmitted in the opposite direction - from the camcorder 20 to the camcorder control unit 24 and are used in calculating the control actions.

Due to the rather high resolution of the video camera 20, which makes it possible to distinguish the TCB in the city traffic stream and “tie” its video image to nearby reference points: houses, intersections, etc., the location of the TCB can be determined quite accurately even with a temporary interruption in the reception of GPS satellite signals receiver 6. This significantly increases the stability of the system with respect to changes in observation conditions and interference conditions and, as a result, provides higher efficiency of interception of fusion.

Thus, the problem of the present invention is solved - a system based on it for searching and intercepting a TCB created on its basis is capable of more efficiently intercepting a TCB than a prototype system.

The technical result provided is to increase the accuracy of determining the location of the TCB in the event of a violation of the stable reception of signals from the global satellite radio navigation system caused by the influence of high-rise buildings and / or the use of deliberate hijackers by hijackers. This result is achieved by introducing into the composition of the equipment installed on board the balloon carrier 10, a video camera 20 and using video images of the TCB and adjacent sections of the road network received from the balloon carrier to “tie” the TC mark to the map-scheme of the controlled city territory. This allows for acceptable accuracy in determining the location of the TCB relative to the elements of the road network (houses, intersections, and other reference points) even in the case of jamming of the GPS receiver by 6 intruders during the movement of the TCB on the road network.
