Description

The invention relates to the technique of centralized radio security of real estate, which uses ground and air based patrol vehicles (TS) (cars, helicopters, aerostat platforms).

Radio channel alarm systems are known that contain a centralized security center, a centralized monitoring station (CMS) and unauthorized sensors (detectors) connected to the monitoring station via object terminals and communication channels installed on guarded objects (or on segments and nodes of an extended guarded object).

These include, for example, the ROSA security alarm system described in patent RU No. 2069055, G 08 C 13/00, 05/20/1996, which contains a block of security sensors installed on stationary objects (or on segments and nodes of an extended guarded object) and a security device, a central control center, comprising a computer with an input adapter and a remote control terminal device in the form of a standard radio station connected via radio to a transmitter of a notification transmission system including a power supply unit and a control unit connected in series transmitter operating modes, encoder timer, signal conditioning device, power amplifier and harmonic filter, the output of which is connected to the antenna, while the output of the security sensor unit is connected to the input of the security device, the output of which is connected to the input of the transmitter operating mode control unit, another input which is connected to the second output of the encoder timer.

The disadvantage of this system, as well as its analogues, is the high cost of object equipment (as a rule, this is at least several hundred US dollars), which is associated with the high radiation power necessary to ensure reliable communication of remote segments of the guarded object with the monitoring station. In addition, when using transmitters with high radiation power, it is more difficult to solve the problem of electromagnetic compatibility, which inevitably arises when constructing any radio channel system (both distributed and with an ordered one-dimensional structure).

The invention of Patent RU No. 2182088, 60 R 25/00, 05/10/2002, is aimed at eliminating these drawbacks. The radio alarm system for centralized protection of real estate objects presented in it contains blocks of stationary security detectors installed on guarded real estate objects (or on segments and nodes of an extended ordered real estate object), connected via buffer devices to stationary object terminals having stationary antennas for communication via airwaves, owners' personal receivers with integrated antennas personal receivers for receiving messages over the air, a data collection and processing center having a handheld terminal device with an antenna of the handheld terminal device for communicating over the air and the monitoring station, which includes information input adapter board connected to each other and connected to the handheld terminal device, an information processing processor, a processing and display unit for cartographic and semantic information, and a printer with a printer adapter, the input of which is connected to the information processing processor made with the possibility of connecting to the processing and display unit of cartographic and semantic information and with the ability to output information to the printer adapter, while the monitoring station is configured to automatically monitor the health of the radio channel by tracking the periodic receipt of notifications from each of the object terminal devices, the radio connection is made the form of a microcellular data network (ISMT) with base stations and repeaters configured to receive code communities s from site terminals, selection and relay these messages to the nearest base station or a repeater.

The use of MRTDs, on the one hand, is the advantage of this system compared to the aforementioned ROSA centralized security system (low radiation power and, therefore, simplicity and accessibility of subscriber equipment), and on the other hand, causes its main drawback, which is the need to increase the number of ground relay devices. This complicates the infrastructure of the system, increases the economic costs of its creation and creates problems of the organizational and technical plan.

To eliminate these shortcomings in the method according to the patent RU No. 2159190, 60 R 25/00, 20.11.2000, selected as a prototype of the present invention, unauthorized attempts to influence any protected object or segment of the protected extended are detected by means of alarm systems of the facility, an appropriate notice is generated containing the identification signs and location parameters of the security alarm installation, which detected an attempt of unauthorized exposure, broadcast over the air a relay or an adjacent alarm installation, the corresponding alarm message, and so on, before receiving the specified alarm message in the quick response center, the identification signs and location parameters of the security alarm installation that sent the alarm message are selected, based on the specified information, the rapid response commands are generated and transmitted on the air to the crews of patrol vehicles, in order to prevent the attempt of unauthorized exposure to the protected object by using skills of rapid response.

The disadvantage of the prototype method is that the duration and the final result of the operation to stop the attempt of unauthorized exposure to the guarded object with the help of quick reaction forces using patrol vehicles depends on various factors (the location of the segment of the extended object that was attacked, the location of the quick reaction forces in beginning of the search, the behavior of intruders, etc.).

The highest price is the long-term deployment of rapid reaction forces in those cases when the object of protection is an extended object with an ordered one-dimensional structure - such as an oil pipeline. As a rule, objects of this type are provided with the strongest protection, which is associated with the high cost of losses arising, for example, due to oil leakage from the oil pipeline. The security system of such objects may include both foot and mobile patrol equipment. Moreover, mobile patrol means can be placed both on land (cars) and on air (helicopters) carriers, which provide the ability to quickly respond to attempts of unauthorized exposure to a guarded object using various countermeasures. The main problem in organizing the protection of extended objects of the "oil pipeline" type is the timely detection and localization of sections (segments) of the protected extended object, in which there were attempts of unauthorized exposure - breaking, penetration, damage (hereinafter, the "alarm segments").

The subject of the present invention is a centralized radio security method using patrol vehicles, in which, with the help of security alarm installations, attempts to unauthorized influence on the guarded object are detected, a corresponding notification is generated containing identification signs and location parameters of the security alarm installation, which detected an attempt of unauthorized influence, transmit the corresponding alarm message containing the notice on the radio on the suck the next alarm setting, the specified alarm message is relayed to the next alarm setting, and so on - until the specified alarm message is received in the quick response center, the identification signs and location parameters of the security alarm installation that sent the alarm message are selected, based on the specified information, the commands are generated operational response and transmit them over the air to the crews of patrol vehicles participating in the operation to curb attempts to unauthorized impact on the guarded object, and when guarding objects with an extended structure after receiving a command of an operative response by the crew of a ground patrol vehicle, a small-sized remotely piloted aircraft (UAV) is launched from its side, which is capable of operating in vertical take-off and landing modes, hovering over by a given point of the earth's surface and horizontal flight according to a given program, video surveillance of the segments of the protected object and adjacent m airborne from the board of the indicated UAV, translate the received video image in real time on board the patrol vehicle, display and analyze the received video image on board the patrol vehicle using fragments of a map of the terrain, transfer the UAV to the horizontal flight mode over the guarded object in the direction to the segment of the object, on which the alarm system was triggered, while the flight parameters of the UAV and video surveillance, as well as the route of movement of the patrol vehicle and the composition of the vehicles used dstv counter tampering protected object corrected for video analysis of the results of the protected object and the surrounding area by the crew of the patrol vehicle.

The invention is aimed at increasing the effectiveness of counteracting attempts of unauthorized exposure to protected extended facilities such as the "oil pipeline", as well as reducing the threat to the safety and life of crew members of ground patrol vehicles.

The ensured technical result consists in obtaining, with the help of the onboard UAV complex, additional information that allows you to choose the most effective and safe tactics for stopping attempts to unauthorized impact on the guarded object.

The invention is illustrated using the drawings shown in figures 1-7.

The considered variant of the radio security system that implements the proposed method of centralized radio security using patrol vehicles contains a chain of security alarm installations 1 along the guarded extended real estate object, such as an oil pipeline, designed to detect attempts of unauthorized interference with segments of the guarded object, formation and broadcasting of alarm messages with the corresponding notices, each of which contains identification signs and location parameters of the security alarm installation 1, which recorded the fact of unauthorized exposure to the protected object.

Detectors are technical means of security and fire alarms - for recording attempts to penetrate a guarded object and signs of fire (see, for example, BOLID advertising materials, autumn 2003, www.bolid.ru). The role of detectors is played by unauthorized access sensors, such as perimeter security sensors, shock sensors, and / or fire detectors, such as temperature sensors, as well as any control and measuring devices that can determine the status of devices installed on segments of a protected extended object, such as sensors of a corrosion protection system .

So, in the aforementioned ROSA security alarm system, up to eight independent loops from unauthorized access sensors are used. In the security system "RIF STRING-200" (RS-200), serially produced by the applicant company, up to four security alarm loops (NORM or ALARM separately and independently for each loop). Accordingly, the object terminal devices of the RS-200 security system have four fixed-purpose alarm inputs (INPUT, PERIMETER, FIRE, ALARM BUTTON), as well as an ARMED / DISARMED input.

Object terminal devices are components of a notification transmission system and are installed at guarded objects to receive notifications from detectors, convert notifications received from them (transfer to a carrier frequency) and transmit them in the form of alarm messages over the air.

Security alarm installations 1 are placed along the long-distance guarded object at such distances from each other that ensure stable transmission of alarm messages along the relay chain - from the initial installation of security alarm 1 to the neighboring security alarm installation 1 and so on - until the specified alarm message is received in center 2 quick response. The quick response center 2 comprises a data collection and processing center 3 and a dispatch center 4 connected via a long-distance communication system, for example satellite communications, to a patrol vehicle fleet. At the same time, on each ground patrol vehicle there is a portable on-board complex 12 and a small-sized UAV equipped with an on-board complex 14 UAVs.

Presented in figure 4, the technical implementation option of the center 3 for collecting and processing information includes a remote terminal device 5, monitoring station 6, a block 9 for displaying cartographic and semantic information, equipped with a geographical information system (GIS), and a printer 10. In particular, a commercial can be used software product "GIS MapInfo" or its modifications. The choice of a specific GIS technology is not essential for the present invention.

The monitoring station 6 contains an information processing processor 8 and an information input adapter 7, the input of which is connected to the output of the console terminal device 5, and the output is to the information processing processor 8, the first output of which is connected to the input of the mapping and semantic information display unit 9, and the second output to the printer 10.

The output of the block 9 for displaying cartographic and semantic information is connected to the input of the dispatch center 4, which has the same composition and structure of communications as the center 3 for collecting and processing information. The construction and operation principles of dispatch centers 4 for controlling patrol vehicles are well known (see, for example, the training manual A.V. Minaev, V.V. Umerenkova "Space navigation systems in the activities of operational services", Orel, 1999).

Monitoring station 6 can be performed on the basis of the RS-200P remote control commercially available by the applicant company (see, for example, the Radio Channel Security Systems Catalog, Altonika LLC, 2003), intended for use in centralized radio security systems of various real estate objects ( trade pavilions, warehouses, garages, summer residences, etc.). The RS-200P remote control is designed to implement all the necessary functions of the monitoring station 6. It has an information input adapter 7 and an information processing processor 8 with a text liquid crystal display (LCD) for two lines of sixteen characters, a relay for controlling various external devices (siren, a dialer, etc.), as well as a standard output for connecting various expansion modules, including a GIS-equipped unit 9 for processing and displaying cartographic and semantic information and a printer 10. All events are logged sya in the electronic protocol of non-volatile memory of the processor 8 information processing. An event is understood as a change in the state of the protected object (alarms of various types, arming and disarming, malfunctions of detectors and object end devices, as well as some actions of the monitoring station 6 operator).

The transportable on-board complex 12 (see FIG. 5) generally comprises a standard radio communication unit 11, as well as a video information reception and display unit 19 equipped with a GIS, and a remote control unit 13, which are components of a typical operator’s automated workstation. The role of the operator is performed by one of the crew members of the ground patrol vehicle. The operator of the on-board airborne complex 12 receives external voice information from the radio communication unit 11, the antenna input of which is connected over the air via a long-distance communication system to the antenna output of the control center 4, and the output is connected to the input of the remote control unit 13 connected via radio to the UAV board.

The onboard UAV complex 14 (see FIG. 6) generally comprises video surveillance equipment 15, an information reception and transmission unit 16, and an onboard control unit 17, the output of which is connected to the flight support organs 18.

Presented in Fig.7 embodiment of the technical implementation of small-sized UAVs developed by Micro Craft Inc. (USA). Fig.7 depicts UAV after landing or during the rise (but not during horizontal flight).

The small-sized UAV passed flight tests in 2000 under the iSTAR program (see Materials of the annual 57th Conference of the American Helicopter Society, Washington, May 9–11, 2001). The specified small-sized UAV contains the following main structural elements: a cylindrical fuselage 20, inside which is the central body 21 of the aircraft with flight support organs 18. The screw 22 is protected by a cylindrical fuselage 20, in the body of which is a fuel tank 23. In the lower part of the central body 21 of the aircraft, control wheels 24 are located, as well as a landing ring 25 to ensure a safe vertical landing. The equipment of the onboard complex 14 UAVs is installed inside the central body 21 of the aircraft. Video surveillance equipment 15 is located in the upper part of the central body 21 of the aircraft. The video surveillance equipment 15 includes a set of sensors and a video camera equipped with a lens 27 of the video camera. In the lower part of the central body 21 of the aircraft is an on-board control unit 17 including miniature piezoelectric gyroscopes, accelerometers, a voltage regulator, and amplifiers (not shown). The central body 21 of the aircraft is attached to the cylindrical fuselage 20 using the rod 26.

When the UAV enters horizontal flight mode over a guarded extended object, the UAV turns around, as a result of which the central body 21 of the aircraft is horizontal, and the video camera with the lens 27 of the video camera is in the nose of the UAV.

The thrust is created by a screw 22, driven into rotational motion by means of a mover with a drive (not shown in Fig. 7).

The basis for the technical implementation of the onboard complex 14 of the UAV, shown in Fig.6, are recent advances in microtechnology, in particular in the technology of microelectromechanical systems. These systems combine planar electronic components with similar-sized electromechanical structures of varying degrees of complexity, which provides unique opportunities for miniaturization of on-board equipment.

In particular, the American firms Analog Devices, Inc. and Texas Instruments freely marketed the ADXL202 microprocessor motion sensor, the ADXSR300 micromechanical gyroscope, the extremely low-power microcontroller MSP430F 149, and a number of other on-board microprocessors.

The considered option for the technical implementation of the claimed method of centralized radio security using patrol vehicles operates as follows.

In case of unauthorized exposure to any segment of the protected extended object, the security alarm installation 1 located on this segment is triggered. In this case, a notification is generated containing identification signs and location parameters of the specified alarm system 1.

This notification is transferred to the high-frequency carrier and transmitted as an alarm message over the air. The specified alarm message is received by the neighboring alarm installation 1 and re-emitted in the direction of the next alarm installation 1, which in this case acts as a relay, and so on, through the relay chain thus formed - to the quick response center 2.

Here, the specified alarm message arrives at the information collection and processing center 3, designed to process the alarm message and form the data complex used by the dispatch center 4 to coordinate the actions of patrol vehicles using a long-distance, for example satellite, communication system.

The processing of the alarm message in the center 3 of the collection and processing of information (see figure 4) is as follows. The received alarm message is sent to the remote terminal 5 and then to the monitoring station 6 (to the information input adapter 7). In the information input adapter 7, the received alarm message is digitized. The code message thus obtained is transmitted to the information processing processor 8, which determines the type of message, selects the identification signs of the security alarm installation 1, which sent the alarm message, and determines the location of the "alarm segment" of the protected extended object where the alarm occurred triggering of setting 1 of the security alarm ("alarm event").

From the information processing processor 8, these data are transmitted to the cartographic and semantic information display unit 9 and to the printer 10. In this case, only the information that is necessary for documenting and long-term storage of the output data in paper form is output to the printer 10.

Operational display of text information is carried out on the LCD processor 8 information processing. The number of the triggered installation 1 of the security alarm, the type of detector and the type of alarm are displayed. In particular, in the aforementioned RS-200 alarm system, special icons can display: alarm messages received on various loops (messages from various detectors, messages about malfunctions of external or autonomous power sources in the corresponding alarm system 1, messages about channel loss communication, etc.).

For a more visual presentation, textual data is displayed in block 9 for displaying cartographic and semantic information against the background of a fragment of a map of the local area diagram containing the "alarm segment" of a protected extended object, for example, an oil pipeline. The specified mapping is carried out in a standard way - using GIS technology. A map of the terrain with an extended object deposited on it is stored in the memory of block 9 for displaying cartographic and semantic information. Fragments of the indicated chart map required for display are selected in accordance with the number of the “alarm segment” of the extended object.

When the operator of the center 3 collects and processes information of the fact of unauthorized exposure to any of the segments of the protected extended object or if the control and diagnostic equipment installed on it malfunctions, the corresponding alarm notification is transmitted to the control center 4. In the control center 4, the corresponding alarm notification is generated rapid response team for the crew of the ground patrol vehicle nearest to the place of the "alarm event". This command is transmitted through a long-distance communication system, for example, via satellite channels to the indicated ground patrol vehicle.

The operational response team is received on board the ground patrol vehicle by the radio communication unit 11, which is part of the transportable airborne complex 12. On board the ground patrol vehicle there is also a small-sized UAV, which can be controlled according to the program set by the operator in real time. The flight mission for the UAV can be set by the dispatch center 4 and arrive at the remote control unit 13 through the radio communication unit 11. The flight mission includes the trajectory, the flight altitude, as well as the coordinates of the points where the video surveillance is turned on (including determining the type of analyzed radiation, for example infrared or visible light). The final adjustment of the flight mission is carried out by the operator on board the ground patrol vehicle. Flight control of the UAV and video surveillance of a guarded extended object are carried out using the onboard complex 14 of the UAV (see figure 5). The UAV is launched vertically by the crew of the patrol vehicle (from a portable container or from a hand).

After dialing a UAV of a certain height and the UAV goes into hovering mode, an operator on board a patrol vehicle activates a given UAV flight program (with a straight path, a snake, etc.) and using a manipulator, for example, a joystick, which is part of the unit 13 of the remote control, corrects the movement of the UAV and the condition of the video surveillance equipment on board 15 (for example, it uses an onboard manipulator of the UAV to remove moisture from the lens 27 of the video camera). Corrective commands are transmitted by the remote control unit 13 to the UAV board, received by the information reception and transmission unit 16, and transmitted from it to the on-board control unit 17, which separates the control commands of the flight support authorities 18 from the commands for switching on and controlling the video surveillance equipment 15. The control commands of the flight support authorities 18 are provided to the flight support authorities 18, and the commands to turn on and control the video surveillance equipment 15 are sent to the video surveillance equipment 15.

The stabilization of the UAV in flight is carried out automatically using the autopilot, which is part of the bodies 18 flight support. Stabilization in a straight flight and in coordinated turns is carried out through three channels: course, roll and pitch. Autopilot control algorithms are generated using the on-board control unit 17 of the microcontroller.

The video image obtained by the video surveillance equipment 15 is transmitted in real time through a block 16 for receiving and transmitting information via a broadband communication channel to a ground patrol vehicle — to the input of a video information receiving and display unit 19 equipped with a GIS. The operator on board the patrol vehicle analyzes the received video image and corrects the horizontal flight of the UAV in the direction of the "alarm segment". After the “disturbing segment" falls into the field of view of the camera lens 27, the operator instructs the camera lens 27 to switch to the observation mode with a narrower field of view than achieving a higher quality image. Image quality can also be improved by putting the UAV in hover mode. In poor lighting, in addition, a transition to the analysis of infrared radiation is possible. The resulting image allows, in particular, to assess whether the attackers are at the crime scene and whether they have weapons. The availability of such operational information can significantly increase the effectiveness of the entire operation and choose adequate means of countering attackers (for example, the use of additional airborne patrol vehicles).

The video images transmitted from the UAV board are raster images suitable for use in a GIS installed in the video information reception and display unit 19.

So, the aforementioned MapInfo GIS provides two options for presenting raster data:

- a single structured raster space in a given coordinate system, connected through a specialized driver of this graphic format;

- single raster files logically combined into layers connected through specialized drivers of this graphic format.

The video images obtained using the video surveillance equipment 15 are combined with the corresponding fragments of the digital cartographic base stored in the memory of the video reception and display unit 19. This allows you to clarify the primary target designation of the "alarm segment" received from the dispatch center 4, and more effectively coordinate the actions of the crew of the ground patrol vehicle.

The video surveillance parameters, the movement route of the patrol vehicle, the composition of the countermeasures and other parameters are adjusted by the crew of the patrol vehicle, based on the results of the analysis of the current video image of the protected object and the surrounding area.

Thus, the proposed technical solution allows to increase the effectiveness of counteracting attempts of unauthorized exposure to guarded extended facilities such as "oil pipeline", as well as reduce the threat to the safety and life of crew members of patrol vehicles.

The ensured technical result consists in obtaining, with the help of the onboard UAV complex, additional information that allows you to select the most effective and safe tactics for stopping attempts to unauthorized impact on the protected object and, accordingly, reduce the degree of dependence of the operation result on various uncertainty factors. The presented sequence of actions has novelty and is practically implemented in the above-described version of the system construction using commercially available hardware and software.
