Description

The invention relates to the field of burglar alarm, in particular to means of monitoring a protected area, designed to detect and identify objects that penetrate into a protected area and cause triggering of technical means of detection when moving objects in a protected area, mainly to technical means of underwater / under-ice protection of offshore oil and gas platforms (MNP) in ice conditions and can be used to protect against penetration of protected objects from water thorium, enterprises energy, Chemical Technology, defense and other profiles from lines in aqueous media, as well as reservoirs, along river banks, in shallow sea, coils, etc.

Currently, MNP security complexes are focused on fulfilling their functions in conditions of water areas free from ice formations. At the same time, in the conditions of the Arctic, ice cover near the MNE remains for 8 months. This makes significant adjustments to the nomenclature of technical equipment intended for the organization of protection of MNEs in ice conditions.

A device for detecting an invasion of an underwater object in a controlled area containing a sonar emitter, reflectors, along an elliptical surface, the foci of which are a sonar emitter and a sonar receiver, the latter being made with a uniform directivity. As a sonar emitter using a transmitting circular antenna (patent RU No. 2150123, 2000 [1]).

It is also known a device containing a protective metal mesh of an intake structure, a low-frequency emitter, a detector and an analyzer of low-frequency signals (patent RU No. 2256196,2005, [2]).

Both devices are complex both in execution and in operation.

A device for the protection of water lines, containing a signal barrier made in the form of a cable stretched over the water along the protected line and mounted on vertical supports, on which poles with loads at the ends in the form of pendulums are suspended, the sensing element is connected to the alarm driver. The sensing element is made in the form of a coaxial cable containing inner and outer conductors separated by insulation from a fluoroplastic tape, the inner conductor is placed in the core of elastically compressible electrically conductive material, the fluoroplastic tape is wound on the inner conductor in a spiral with positive overlap, the protective sheath is concentrically located on the outer conductor , the coaxial cable is laid under the cable along its axis and is rigidly connected to each pole (copyright certificate SU No. 1819024,2000 [3]). The disadvantage of this device is the low sensitivity (detection only with a direct impact on the device) and the short duration of the act of detection. False alarms are also possible in contact with mechanical impact devices, for example, flooded objects.

A device for protecting water lines is also known, containing a signal barrier in the form of a cable stretched above the water along the protected line and mounted on vertical supports, a coaxial radio-frequency cable mounted on the cable along its entire length and connected by its central conductor through an isolation capacitor to the input of the formation device an alarm signal, and a sensitive element made in the form of pieces of a piezoelectric cable with loads at one end, suspended from opposite ends, in the points of attachment of the coaxial RF cable to the cable, the segments of the piezoelectric cable are connected to the RF cable using matching devices, powered from a common power supply source through a load resistor connected between the output of the power supply voltage and the central conductor of the coaxial RF cable, and the second pole of the power supply source is connected with a shielded grounded braid of a coaxial radio frequency cable (patent RU No. 2375755, 2009 [4]).

The known device [4] is sensitive to the effects of interference excited in segments of a piezoelectric cable by a natural factor - displacement relative to segments of water masses caused by wind or tidal phenomena, which leads to the generation of false alarms or even the admission of an intruder. The voltage of the noise excited by the natural factor, and the width of its frequency spectrum depends on the speed of movement of water masses relative to the segments of the piezoelectric cable.

Equivalent drawbacks are also known similar devices (patents RU No. 2364883 C1, 08.20.2009 [5], RU No. 79678 U1, 03.27.2011 [6], RU No. 2271551 C2, 03/10/2006 [7], US No. 5664907 A1, 07/08/1997 [8], US No. 5481505 A1, 02/01/1996 [9], US No. 5305286 A1, 04/19/1994 [10], application US No. 20090201763 A1, 08/13/2009 [11], WO No. 2008/093088 A2 , 07/08/2008 [12], GB patent No. 2238121 A, 08/13/2009 [13]).

The technical result of the well-known device for the protection of water borders is to reduce the sensitivity to interference caused by natural factors (patent RU No. 2568781 C2, 11/20/2015 [14]).

In this case, the technical result is achieved by the fact that in the device for the protection of water boundaries containing a signal barrier in the form of a cable stretched above the water along the protected line and mounted on vertical supports, a coaxial radio frequency cable mounted on the cable along its entire length and connected by its central conductor through a separation capacitor with the input of the alarm signal generating device, a sensitive element made in the form of pieces of a piezoelectric cable with loads at one end, hung from opposite ends at the points of attachment of the coaxial RF cable to the cable and connected to the RF cable using matching devices powered from a common power supply source through a load resistor connected between the output of the power supply voltage and the central conductor of the coaxial radio frequency cable, and the second pole of the power supply source voltage is connected to a shielded grounded braid of a coaxial RF cable, under water along a guarded line omnidirectional electro-acoustic emitters are installed, equidistant from each of the loads of the piezoelectric cable segments, in-phase connected via a separate communication line with a voltage generator of the kilohertz frequency range, and all connections are sealed.

A disadvantage of the known device [14] is that the signal fence is made in the form of a cable stretched above the water along the guarded line and mounted on vertical supports. Under adverse weather conditions, a squally wind, high waves, ice formation in the northern latitudes, the operational reliability of such a device is not high.

Monitoring of vast territories was initially associated with the presence of a central control center, a significant number of technical means of detection, as well as an extensive system of information transfer (radio communication channels). Such monitoring is well-known and is implemented as a variant of a two-level system in which each technical means of detection through a radio channel is connected directly to a central control center. The presence in this system of a large number of technical means of detection determines the increased requirements for the organization and tuning of radio channels for reliable delivery of alarm messages to a central control center.

Well-known security systems implemented in the form of two-level systems. For example, the Perimeter Protection System “Radioureb” is known, described in the utility model patent RU No. 129283 U1, 2013 [15]. The system comprises a block of detection means and a block for collecting and displaying information. The block of detection tools contains motion sensors operating on various physical principles: passive infrared sensors (IR), active radio-beam on-off sensors, and active vibration triboelectric sensors. Communication between all motion sensors and the information collection and display unit is carried out using a 433 MHz radio channel. The system provides an extension of the protection and monitoring zone of objects with which there are no wired communication lines. When an intruder is detected, the sensors generate an alarm notification and transmit it through neighboring sensors, which in this case work as repeaters, to the information collection and display unit.

Similar significant features are: sensors operating on various physical principles, a unit for collecting and displaying information, communication between all sensors and a unit for collecting and displaying information using a radio channel (lack of wired communication lines).

The disadvantage of the system is the inability to monitor protected areas by visual identification of the person-offender to distinguish him from animals, birds and other interference factors.

The well-known "Mobile complex of technical means of protection" described in patent RU No. 2427039, 08/20/2011 [16]. The complex contains a control point, optical-electronic means of a three-dimensional circular viewing based on television and thermal imaging equipment, and a perimeter security system consisting of perimeter detection tools and perimeter optical-electronic surveillance devices. The perimeter security system consists of N local security posts, each of which contains a transmitter and a receiver of on-off radio-beam detection means, passive infrared detection means, a thermal imager and a sensor for detecting the intruder's proximity to the local guard station (explosive detection means). All detection and surveillance tools incorporate radio transmitters that transmit information to the control center. This complex provides control of the ground and air space of the protected area. Upon detection of the intruder, its visual classification is made, targeting of the optoelectronic means of a three-dimensional circular review and escort of the intruder in a controlled space.

Similar essential features are: a control point, a perimeter security system consisting of local security posts, perimeter detection devices (radio-beam, passive infrared, explosive) and perimeter optical-electronic surveillance devices.

The disadvantages of the known complex are:

1) the absence in the complex of two-way radio communication between the control center and the remaining components of the complex, which limits the functionality of the complex (the control center provides one-way reception of radio signals and there is no possibility to configure the components of the complex and manage them);

2) information transfer in the complex is carried out on one radio frequency of the radio communication channel, which complicates the simultaneous reception of actuation signals from detection means and video information from observation means.

All these disadvantages are partially eliminated in the well-known system of intelligent sensor network ", described in US patent No. 8710983,2014, [17]. The system contains a group of nodes of a network of sensors (technical means of detection) and a gateway (central control point). The group of nodes of the sensor network and the gateway form one ranked radio network, the transmission of information in which is carried out by selecting routes according to the criterion of the best quality of radio communications. The structure of each of the nodes of the sensor network (technical means of detection) includes: from one to N sensors (alarm) operating on different physical principles, a network module (radio modem), an activity detection module, a processor with a memory module, and a power source. The processor is designed to process information from alarm sensors and form routes for transmitting information to the gateway (central control point). The memory is designed to store processing and routing algorithms. The gateway (central control center) includes: a central processor (personal electronic computer) with a graphic monitor, a connection module (communication module) and a network interface module (radio modem). The communication module is designed to provide communication between the system and external devices (servers, portable control panels, etc.) using LAN, WAN or Ethernet interface. The nodes of the sensor network (technical means of detection) can be in "sleep" (sleep) mode, providing a mode of low power consumption. The activity detection module is designed to switch the sensor network node to the active mode to detect the object of violation of the guard line. Power sources can be made in the form of rechargeable or solar batteries, as well as in the form of other alternative power sources.

Similar essential features are: a gateway (central control center) and a group of nodes of a network of sensors (technical means of detection); included in the gateway (central control point) - a radio modem, a communication module, and a personal electronic computer with a graphic monitor; included in each of the nodes of the network of sensors (detection equipment) - a radio modem, an activity detection module, a processor with a memory module, a power source, and alarm sensors (from one to N), operating on different physical principles; radio modems made with the possibility of receiving and transmitting information between the gateway (central control center) and a group of nodes of the sensor network (detection equipment), interconnected into a single rank radio network and configured to automatically reconfigure information transmission routes according to the criterion of the best radio quality.

The disadvantage of the system is the inability to monitor protected areas, taking into account the visual identification of the person-offender to distinguish him from animals, birds and other interference factors.

The elimination of this drawback is provided for in the well-known technical solution (patent RU No. 2629521 C1, 08/29/2017 [18]), by using small-frame CCTV systems capable of highlighting pre-alarming, alarming and after alarming video information for reliable visual identification of detected objects; separation of communication radio channels by frequencies for transmission to the central control center of alarm messages from technical means of detection and video information from technical means of video surveillance; providing with technical means of detection and video surveillance technical means of relaying transmitted messages to a central control center; the possibility of changing the algorithms for processing the information received at the central control point from the technical means of detection, taking into account the physical principle of operation of alarm sensors, their location on the ground, the current operational situation in the protected area and a certain direction of movement of the detected object.

In this case, the task is achieved through an intelligent network monitoring system of the protected area, which contains a central control center and a group of detection equipment, the central control center includes a first radio modem operating on the radio frequency of the first radio channel, a communication module with the ability to communicate with external devices using network interface and personal electronic computer with a graphic monitor, each technical detection means includes the first radio modem, an activity detection module, a processor with a memory module, a power source and alarm sensors (from one to N), operating on different physical principles, the first radio modems are capable of receiving and transmitting information between the central control center and a group of technical detection tools that are interconnected in the first one rank radio network operating on the radio frequency of the first radio channel and made with the possibility of automatic tuning information transmission routes according to the criterion of the best quality of radio communications, the system includes a group of video surveillance equipment containing small-frame video surveillance systems that are capable of highlighting pre-alarming, alarming and post-alarm video information, while each video surveillance equipment contains a second radio modem operating on the radio frequency of the second radio channel communication for transmitting video information to a central control center, which includes for receiving video information Modes enabled second radio band video technical means and central control unit are interconnected to a second one the rank radio network operating at a radio frequency of the second radio communication and capable of automatic adjustment information transmission routes for the best radio quality criterion.

At the same time, alarm sensors included in the technical means of detection are configured to operate as seismic alarm sensors with the classification of the intruder (“single”, “group”, “vehicle”) and the determination of the direction of movement (“to us”, "from U.S"); radio wave alarm sensors for working on terrain with complex terrain; passive infrared alarm sensors; magnetometric alarm sensors with the determination of the presence of a metal weapon in the offender (“armed” or “not armed”); one-position or two-position radio-beam alarm sensors; breakaway alarm sensors.

The group of detection equipment by the number of types of alarm sensors used consists of a different combination of seismic, radio waves, infrared, magnetometric, radio beam and breakaway alarm sensors.

The algorithms for processing information received at the central control point from the technical means of detection are selected taking into account the physical principle of operation of alarm sensors, their location on the ground, the current operational situation in the protected area and a certain direction of movement of the detected object in accordance with the decisive rules “I”, OR, 2 of 3. Information processing algorithms can be selected with the possibility of combining signals from alarm sensors working on different physical principles, as well as with the possibility of using neural network algorithms and fuzzy logic algorithms for intelligent information processing in a central control center.

The personal electronic computer, which is part of the central control center, is made in the form of an operator's automated workstation, which is provided with archive memory, an alarm notification system and the necessary software package with the ability to display the terrain plan on a graphic monitor screen, designation of technical means on the terrain plan detection and technical means of video surveillance, as well as with the possibility of recording alarm signals of technical means about appearance and video information coming from technical means of video surveillance.

A disadvantage of the known intelligent network system for monitoring a protected area [18] is that the basis of such a system is radio wave and infrared sensors operating in the air, which significantly narrows the scope of such a system, i.e. This system is operational only on land. In addition, the known system does not solve the problem of protecting the territory when unauthorized objects enter it by air.

At the same time, there are a number of objects of marine economic activity (OMHD) such as onshore hydrocarbon storage facilities, ports, surface and underwater marine loading terminals of hydrocarbons, offshore production platforms, which are objects of increased risk in terms of possible sabotage. For the protection of offshore platforms for hydrocarbon production in clean water, sonar and optical devices are traditionally used.

In ice conditions and with the possible negative impact of international competitors on the operation of underwater mechanisms of wellhead equipment, it is necessary to solve the problem of early detection of underwater objects (software) approaching the MNP with the aim of disrupting its operation. For the conditions of the Arctic, such a malfunction is extremely dangerous, given the large range of nodes and mechanisms of wellhead equipment located near the ground. For example, supporting structures, fountain fittings, preventers, risers, wellheads, leakage pipe shutoff valves, control system electrical cables, hydraulic hoses and preventer gas pipelines, etc. Their destruction is a serious threat to the MNP (Karaev RN Assessment of the accident rate of offshore oil and gas facilities. Journal of the Marine Bulletin No. 3 (59). - 2016. - pp. 85-90 [19]).

Therefore, the protection of such underwater equipment in the work area becomes essentially a national environmental and economic problem.

To address the issues of MNP protection, a large nomenclature of uninhabited underwater vehicles (NPA) has been created which, to one degree or another, corresponds to the tasks set.

The class of inhabited autonomous underwater vehicles (OAPA) is mainly intended for software detection using optical (or directly visual) surveillance systems. However, already in the 70s the operation of foreign devices revealed their unsuitability for great depths, there was a disappointment in their effectiveness. The intensity of the use of OAPA for servicing MNEs and, as a result, their construction sharply decreased.

The class of NPA represented mainly by autonomous and remote-controlled devices, on the contrary, is rapidly developing, proving its preference. In the same years, underwater technologies firmly established the direction of tethered (telecontrolled via cable) NPA. This class of vehicles is rapidly developing in foreign and domestic underwater technologies, as it has established itself as a reliable, safe and effective means of working under water.

The existing fleet of telecontrolled NPA (TNPA) is quite wide. Their equipment with a set of underwater tools allows you to replace the work of deep-sea divers, and the use of submarines provides in marine practice a solution to the main problem - weather resistance.

Design organizations are paying more and more attention to this class of regulations, which can ensure reliable operation and protection of MNPs in ice conditions.

The class of autonomous regulatory acts (ANA) is mainly focused on research functions, observation, inspection, relaying of information. These activities occupy a rather narrow niche of underwater operations. Their use for joint work with MNEs in specific marine practice is problematic.

Work on the creation of multi-purpose APA is at the research stage and far from implementation (A.A. Naumov, Yu.V. Matvienko. Status and prospects of development of IPMT FEB RAS works. Internet source: http://www.imtp.febras.ru /images/stories/konf/tpomo-4-3-7-oktjabrja-2011-goda/pdf/plenarnye-doklady.pdf [20]).

Separate samples of AUVs that perform the functions of research and transmission of information through the hydroacoustic (GA) channel (the so-called underwater platforms) are at the stage of conceptual decisions

(A. Kurnosov. In one person - a sapper and a sentry. An article in the Russian newspaper “24 hours”, No. 16. - 2016 [21]).

Some APN A are devices of the type of underwater gliders (gliders), for example, of the Glider-T type and others (V. Seredin. Underwater gliders. Article in the Russian newspaper “24 hours”, No. 9. - 2015 [22]) which are unsuitable for use in ice conditions due to the fact that during the period of operation, devices of this type must float to a water surface free of ice formations to clarify the location of the device or to transmit information by radio.

In addition, the energy intensity of such devices is insufficient to perform maneuvering near the MNP or to move a dangerous unauthorized object to a safe distance by means of the device, the lack of a manipulator and operational visual communication with the operator - all this makes the devices practically unsuitable for working in ice conditions using standard MNP mechanisms . In addition, the descent (ascent) of such devices under the ice from the platform is practically not resolved.

According to a number of indicators for the conditions of the Arctic, in the presence of ice fields, the most preferable are attached TNLA, which have manipulative devices, a high degree of maneuverability, and are multifunctional and have almost unlimited power consumption. At the same time, two-way transmission of information and control commands via cable is provided with virtually no interference. Hoisting operations with a similar class of vehicles, as a rule, are carried out by the mine method, thereby eliminating the influence of weather conditions.

Similar TNLAs having practical application are also known.

For example, a mobile complex of underwater technical works (MKTPTR), which includes TNPA with a manipulator; OPA; side-scan sonar and which is intended for inspection and detection of objects of work with a manipulator device (A.G. Khramov. Innovative projects of LLC “Dayvtehnoservis” for emergency rescue diving and underwater technical works. In the collection of reports of the International Scientific and Practical Conference. - SPb. 2013 - Internet source https://elibrary.ru/item.asp?id=24362304 [23]). However, for work in ice conditions, the TNPA used in the system is practically unsuitable.

Also known is a system of passive identification and monitoring of underwater conditions; it includes an underwater robot equipped with a sonar station (GAS), video cameras, and strain gauges; passive GA beacon located on the ground.

This system is designed to monitor the underwater infrastructure of MNEs in ice conditions (Passive identification and monitoring system for underwater infrastructure of oil and gas production and hydraulic structures in complicated Arctic conditions. In the collection of materials of the 3rd International Forum “Arctic-Present and Future.” St. Petersburg 2013 Internet - source http.//narfu.ru/upload//medialibrary/aac/sbornik-tezisov-samit_2014.pdf [24]). The disadvantage of the system is that it is based on foreign models of underwater vehicles and devices.

The well-known mobile complex of engineering and technical means of physical protection to ensure the protection of ships and port facilities (MK ITSFZ) contains GAS; optical systems; perimeter alarm system; neutralization system (Internet source - http://www.tetis-ks.ru/catalog/233/ [25]) and is designed to protect port facilities.

Designs of analogues have the traditional equipment of devices by search channels, ways to improve the design of devices, reducing weight and size characteristics.

This approach to design allows us to characterize the laws as a complex, that is, as a set (set) of search channels that make up one whole.

At the same time, the components of the complex are in informational relations or in relations with each other, which allows to form a certain integrity, unity.

This approach ensures the creation of a system that cannot be traced in existing complexes.

As a prototype, a set of engineering and technical means of protecting MNPs has been selected in terms of protecting the territory from the sea (Fig. 2), similar to the MNP Prirazlomnaya ([26]).

The complex contains a typical set of technical equipment for lighting underwater conditions:

- GAS all-round visibility in a complete set with bottom antennas;

- side-scan sonar (HBO);

- TNPA.

The last two funds are placed on a surface carrier (boat).

The purpose of the complex is to “illuminate” the underwater space in the area of the MNP with the aim of detecting software, subsequent recognition and classification by means of HBO and the underwater vehicle. If necessary, it is possible to neutralize the detected software HA by means of a surface carrier. In stormy conditions, the effectiveness of a small-sized surface carrier (GA vehicle) is extremely low.

In ice conditions, the boat is on board the MNP and, accordingly, the complex is inoperative.

The intellectual network system of the protected area [18] and the complex of engineering and technical means for protecting MNPs of the Prirazlomnaya type [26] are considered as a prototype.

The objective of the present invention is to expand the functionality of the system of underwater protection of the oil and gas platform in ice conditions by increasing the operational reliability of the device for the protection of water borders.

The problem is solved due to the fact that in the intelligent network monitoring system of the protected area of the oil and gas platform in ice conditions, containing a central control center (CPU) and a group of detection equipment (TCO), the CPU includes the first radio modem operating on the radio frequency of the first communication channel , a communication module with the ability to communicate with external devices using a network interface and a PC with a graphic monitor, each TCO includes a first radio modem, a detectable module activity, a processor with a memory module, a power source and alarm sensors (from one to N) operating on different physical principles, the first radio modems are capable of receiving and transmitting information between the CPU and the TCO group, which are interconnected into the first peer-to-peer radio network operating on the radio frequency of the first radio channel and made with the possibility of automatic adjustment of information transmission routes according to the criterion of the best quality of radio communications, the group includes a technically video surveillance equipment (TSV) containing small-frame video surveillance systems configured to isolate pre-alarm, alarm and post-alarm video information, each TSV contains a second radio modem operating on the radio frequency of the second radio channel for transmitting video information to the CPU, which is additionally included for receiving video information the second radio modem, the TSV group and the CPU are interconnected into a second peer-to-peer radio network operating on the radio frequency of the second radio communication channel and executed with the possibility of automatically reconfiguring information transmission routes according to the criterion of the best quality of radio communications, the TCO group by the number of types of alarm sensors used consists of a different combination of seismic, radio wave, infrared, magnetometric, radio beam and breakaway alarm sensors, processing algorithms for the information received from the CPU TCO, are selected taking into account the physical principle of operation of alarm sensors, their location on the ground, the existing opera conditions in the protected area and a certain direction of movement of the detected object in accordance with the decisive rules "I", "OR", "2 of 3", the algorithms for processing information received in the CPU from the TSO are selected with the possibility of combining signals from alarm sensors, working on different physical principles, as well as with the possibility of using neural network algorithms and fuzzy logic algorithms for intelligent information processing in the CPU, the PC that is part of the CPU is made in the form of an automaton operator's workstation (AWS), which is provided with archive memory, an alarm system and the necessary software package with the ability to display the terrain plan on the screen of a graphic monitor, designation on the terrain plan of TSO and TSV, as well as the ability to register TSO alarm signals and video information, coming from TSV, which also includes a complex of underwater technical equipment, including bottom sonar stations located near the platform with the formation of a far zone detection, side-scan sonar, telecontrolled uninhabited underwater vehicle, in which ice beams drifting near the platform are placed with GLONASS navigation equipment and sonar stations, the antennas of which are mounted via an external cable via a cable, and high-frequency onboard antennas are installed on the platform sonar station, forming a protective circular near working zone of recognition (classification), found in the far zone of the underwater object CTA or an unauthorized object, the neutralization of which is carried out by a remote-controlled uninhabited underwater vehicle with a manipulator located in the underwater launching and lifting device of the platform and automatically aiming at the object at the signal of the onboard sonar station or operator, the security module of the mechanisms of wellhead oil and gas equipment in the working area is designed as an underwater television complex included in the work on the signal of the onboard sonar station, an additional device a detector for detecting and classifying a reducer, comprising a sonar that contains a series-connected threshold selection unit and echo signals detection, a unit for measuring the amplitudes and times of detected echoes, a classification feature generation unit, a decision unit, and which is connected via a multi-channel receiving device to a processor connected with an indicator unit for the operator, a periodic generator including a source of high-voltage nanosecond pulses, a gyromagnetic line with Ni Zn ferrite, a high-pass filter, a radiating and receiving antenna, the output of which is connected to the corresponding input of a multi-channel receiving device.

In the proposed technical solution, in order to increase the area of GA observations and determine the coordinates of moving under ice towards the MNP, GA buoys are set up on ice fields drifting near the MNP, similar to the well-known method for placing GA (Zimovshchikov will be replaced by machines on ice machines. Russian newspaper “24 hours” No. 16, 2017 [27]). At the same time, ice fields are used as instrument platforms.

Currently, ice field drift routes have been studied with great accuracy for a long time. GLONASS navigation equipment is located in the “surface” part of the buoy, which makes it possible to determine its coordinates with respect to the MNP. The “ice” part of the buoy connects (suspension) the GAS antenna with the cable of the “surface” part of the buoy via a cable cable. Similar technical solutions (pop-up buoys - emergency information device “Paris”, V-600, V-603, marine emergency radio beacon ARB ISS “Afalina”, emergency GA signaling device MGS-30, emergency GSM signaling system MG-35) are widely known in the system Navy of the Russian Federation (Alert means for the accident of designating the place of an emergency submarine and communication with its personnel in the book of OM Slesarev. Rescue equipment of the device and system of submarines. Publishing house "Nestor-Istoriya" .- 2012 [28]) .

The system constructed in this way allows you to create an informational connection between buoys and MNPs with the formation of a far detection zone (DZO), and the MNP side-scan sonar provides the near working zone (RHL), as well as pointing to the detected unauthorized TNPA software. The joint work of the navigation system and underwater systems allows you to trace the trace of unauthorized software. The combination of space and surface information fields forms a certain integrity, the unity of individual security elements, which is characterized as a system.

Further support of unauthorized software is based on its identification and classification.

To this end, on the underwater section of the MNP case, high-frequency HAS antennas are placed along its perimeter. The antenna field forms a circular RHZ, where the type of unauthorized software, its course, and coordinates of movement are determined.

The neutralization of unauthorized software is carried out by TNLA, equipped with optical means and a manipulator with a set of underwater tools.

TNLA service is carried out by a launching and lifting device (SPU) located in the underwater part of the MNP. Real-time operational information is carried out in both directions by means of a cable cable.

Control of the control system (filling the container shaft, opening the hatch, device exit, etc. actions) can be performed both automatically from the HA systems, and at the command of the operator.

In terms of protecting the territory in coastal conditions, the monitoring system is similar to the prototype [18]. Moreover, the system monitors the protected area in an open area.

In FIG. 1 shows an example of a structural diagram of a system for monitoring the perimeter of a guarded object according to the prototype when monitoring the coastal part of the MOHD.

The intruder shown in FIG. 1, conditionally penetrates into the protected area in the direction indicated by the arrow. One of TCO 2 in FIG. 1 (in the lower right corner) is shown on a larger scale to show its components.

In FIG. 2 designations are introduced: MOKhD - 19, distant detection zone (SAC) - 21, underwater or surface unauthorized object - 22, drifting ice fields - 23, beacon - 24, RNS "GLONASS" - 25, cable - cable suspension antenna GAS - 26 , GAS - 27, forming a SAC, circular near working zone (BRZ) - 28, onboard high-frequency antennas GAS - 29, TNPA - 30, radar station - 31, launching device - 32, navigation satellite - 33, gyromagnetic line 34, underwater television equipment 35, explosive identifier 36, laser module 37, weather station 38.

The system according to the prototype monitors the protected area in an open area. In FIG. Figure 1 shows an example of the location in the protected area of TCO 2 and TSV 11, the number of which is set based on the size and configuration of the protected area. TCO are connected with each other and with the CPU 1 through the first radio channel 10, forming the first single rank radio network at a frequency (433 MHz) of the first radio channel. TSV are also connected with each other and with the CPU 1 through the second radio communication channel 13, forming a second single rank radio network at a frequency (868 MHz) of the second radio communication channel. The principle of operation of peer-to-peer networks is well known and described in detail, for example, in US patent No. 8710983.

The CPU includes the first 3 and second 12 radio modems, operating, respectively, on the radio frequencies of the first 10 and second 13 radio channels, a communication module 14 with the ability to communicate with external devices (servers, portable control panels, etc.) using a network interface 15 (LAN, WAN or Ethernet interface), as well as PC 4 with a graphic monitor 5. TCOs are configured to receive control information from the CPU, as well as transmit alarm signals to the CPU. TSVs contain small-frame video surveillance systems made with the possibility of highlighting pre-alarming, alarming and after alarming video information, and provide receiving control information from the CPU, as well as transmitting video information to the CPU. All TSO and TSV automatically perform the function of relaying the transmitted messages within their radio networks. The first and second single-rank radio networks used are self-organizing and are configured to automatically restructure information transmission routes according to the criterion of the best radio quality. To ensure the indicated information transfer, the TSO radio exchange zones and the TSV radio exchange zones (Fig. 1) intersect in space.

The principle of operation of the system is illustrated by the drawings depicted in FIG. 1-2. When an object (for example, a person-offender 16) penetrates the protected area (the arrow shows the direction of its movement), an appropriate TCO will generate an alarm with “its” TCO number (address), which will be transmitted using the first radio channel 10 to the CPU. In the case of using TSV in the form of video monitoring points of a low-frame mobile video surveillance system, each of them transmits video information on the promotion of the intruder 16 with the number (address) of the corresponding video monitoring point to the CPU via the second radio channel 13. Thus, the CPA records the fact that the person-violator crossed the border of the protected area and receives reliable information about the consistent advancement of the person-violator in the monitoring zone, indicating the numbers (addresses) of the TCO, the time moments of crossing the detection zones, and also captures video information on his progress.

Each TCO 2 includes a first radio modem 3, an activity detection module 6, a processor 7 with a memory module 8, a power supply (not shown in FIG. 1), and alarm sensors 9 (from one to n) operating on different physical principles. The processor 7 is designed to process information from alarm sensors 9, and the formation of information transmission routes to the CPU 1. The memory module 8 is designed to store processing and routing algorithms. Power sources can be made in the form of rechargeable or solar batteries, as well as in the form of other alternative power sources. TCO 2 may include seismic alarms, radio wave alarms, passive infrared alarms, magnetometric alarms, single or dual-beam alarms and breakaway alarms. Combinations in TCO of alarm sensors with various physical principles of action are possible.

TCO can be configured to detect a person-violator, or to detect larger objects, such as cars and trucks, tracked and horse-drawn vehicles. To implement the secrecy (or maskability) of the system, it is recommended to use seismic or radio wave alarm sensors as TCO. Such sensors can be BSK-S point seismic sensors (BAZHK.425139.010) and BSK-RVP radio wave sensors (BAZHK.425142.058). Seismic alarm sensors, proposed for use in the system, provide a classification of the detected object ("single", "group", "vehicle") and determine the direction of movement ("to us", "from us"). BSK-RVD radio wave alarm sensors (BAZHK.425142.048) provide operation on terrain with complex terrain (hills, ravines, rocky terraces, wooded, swampy and dense vegetation terrain, ice hummocks, sand dunes, etc.). To monitor the penetration by a human-intruder into the territory of a protected object of metal objects (for example, firearms and cold steel), magnetometric alarm sensors can be used as TCO to ensure the formation of signals for the presence of metal weapons (“armed” or “not armed”). Such sensors can be BSK-MSO magnetometric sensors (BAZHK.425113.005). For the creation of rapidly deployable places of temporary basing of people, vehicles, material assets on long, even sections of the terrain, one-position radio-beam (BSK-RLO, BZHAK.425142.050) and two-position (BSK-RLD, BZHAK.425142.051) alarm sensors can be used. In hard-to-reach areas of the terrain (roads, forest paths, mountain passes, gorges, ravines, etc.), infrared passive alarm sensors BSK-IK (BZHAK.425152.003) can be used. To detect the penetration of unauthorized persons into the protected area, blocking window and doorways, various kinds of fences, walls, etc. BSK-O breakaway alarm sensors (БЖАК.468173.026) can be used. All of these alarm sensors are described in detail in the materials on the website www.nikiret.ru.

Processing of information received from the TSO is carried out in the CPU according to the selected algorithm according to the criteria of the maximum probability of detection or the minimum number of false alarms and taking into account the physical principle of operation of alarm sensors, their location on the ground, the existing operational situation in the protected area, as well as a certain direction of movement object. Information processing algorithms are selected in accordance with the decisive rules “AND”, “OR”, “2 of 3” depending on tactical tasks. Information processing can be selected with the possibility of combining signals from alarm sensors working on different physical principles, as well as with the possibility of using more complex intelligent signal processing algorithms: neural network algorithms and fuzzy logic algorithms (Fuzzy Logic). The fuzzy logic algorithm for signal processing is a well-known algorithm and is used, for example, in radio-beam alarm sensors of the ERMO 482X PRO series by CIAS (www.cias-russia.ru). The neural network algorithm is also well known, which is described, for example, in the article by A.Yu. Zenova and N.V. Myasnikova "Application of neural network algorithms in perimeter security systems" / News of higher educational institutions. Volga region. Technical science. - 2012. - No. 3 (23) - p. 15-24. The use of these intelligent algorithms will significantly improve the tactical and technical characteristics of the proposed system in terms of more reliable detection of intruders and increase its noise immunity.

The information channel for the exchange of information in the system is represented by two radio channels of communication. The first 10 and second 13 radio channels are proposed to be used in different frequency ranges (for example, the first radio channel at a frequency of 433 MHz, and the second radio channel at a frequency of 868 MHz). The use of two radio communication channels separated by radio frequencies allows to unload the information channel (network) of information exchange in the system by dividing the transmission of alarm messages and the transmission of video information into two independent first and second single-rank radio networks.

In the monitoring zone, video monitoring points of a low-frame mobile video surveillance system, which are described in patent RU No. 2504015, IPC G08B 25/08, publ. 01/10/2014. The Cypress-Video surveillance system (BAZHK.463349.003), made in accordance with the specified patent, as well as the similar Camouflage-Video surveillance system (BAZHK.463349.005) are presented in the materials on the website www.nikiret.ru.

TSV work as follows. By alarms in automatic mode or at the command of an operator with the CPU, the cameras of these video monitoring points are turned on, which are designed to transmit frames of the video image in the zone where the cameras are located on the CPU. The transmitted video information is necessary to make a decision on the threat that has arisen. Video monitoring points of a low-frame mobile video surveillance system can be used in two versions: with observation zones directed in one direction and with observation zones directed in different directions.

In the known system, it is possible to turn off some TCOs to ensure that they are in a "sleeping" state (sleep mode), which in turn reduces the total power consumption of the system in standby mode, as well as during, for example, repair or routine maintenance. To transfer from the "sleeping" state to the active mode of operation, each TCO has an activity detection module 6, which "wakes up" the TCO from the "sleeping" state when signal modulation occurs in the detection zones of alarm sensors.

The intelligence of the known system is ensured by the fact that the following features can be used in it:

- taking into account weather conditions in order to adjust processing algorithms (for example, during rain, hail, strong wind, fog, etc.);

- interrogation of the state of neighboring TSOs with the aim of making a final decision about the alarm situation at a certain section of the guard line (for example, during a thunderstorm or strong gusts of wind);

- accumulation and storage of routing algorithms for use in possible options for the organization of radio networks in the future;

- accumulation of data to take them into account when analyzing the state of TCO and TSV in the event of similar situations in the future;

- analysis of pre-alarming, alarming and after alarming video information coming from TSV;

- the use of sleep mode (sleep) to save power by the system;

- distribution and redistribution of computing resources between CPU, TSO and TSV;

- the use of information about the distance to the place of violation, the parameters of the object of violation, the speed and direction of its movement through the guarded border to identify the object of violation by class (person, small animal or bird, vehicle), which gives additional information to the security service to detain the violator;

- the use of processing algorithms with a combination of signals from alarm sensors working on different physical principles;

- the use of neural network algorithms and fuzzy logic algorithms for intelligent information processing in the CPU.

The PC 4, which is part of the CPU 1, is designed as an operator's automated workstation (AWP), which is provided with archive memory, an alarm system and the necessary software package with the ability to display the terrain plan on the screen of a graphic monitor, designations on the terrain plan of TSO and TSV , as well as with the possibility of recording TCO alarm signals and video information coming from the TSV. Viewing video information is carried out on a graphical monitor 5 PC. Alarms with TCO addresses (numbers) and received video information are stored in the PC memory.

Each of the TSO and TSB in the system may include an integrated GPS receiver, which can be used to link the components of the system to a local or geographical coordinate system.

The weather conditions are provided by obtaining the necessary information from the weather station 38. For marine DCD, the weather station is installed directly on the DCD, the information outputs of which are connected to the information inputs of the CPU.

When limiting the range of radio channels, the use of appropriate repeaters is allowed.

In contrast to the prototype, the intelligent monitoring system of the protected area additionally contains ice beacons with GLONASS navigation equipment and sonar stations drifting near the platform's ice fields, the antennas of which are mounted via an external cable via a cable, and antennas of a high-frequency onboard sonar station are installed along the perimeter of the platform , forming a protective circular near working zone of identification (classification) found in the far zone of the underwater object CTA or an unauthorized object, the neutralization of which is carried out by a remote-controlled uninhabited underwater vehicle with a manipulator located in the underwater launching and lifting device of the platform and automatically aiming at the object at the signal of the onboard sonar station or operator, the security module of the mechanisms of wellhead oil and gas equipment in the working area is designed as an underwater television complex included in the work on-board sonar station signal, an additional device for detecting and classifying a reducer, comprising a sonar, which through a multi-channel receiving device, through a processor, which includes a series-connected threshold selection unit and echo signals detection, a unit for measuring the amplitudes and times of detected echo signals, a classification feature generation unit, a decision making unit, and through an indicator connected to the operator unit, a periodic generator including a source of high-voltage nanosecond pulses, a gyromagnetic line with NiZn ferrite ohm, a high-pass filter, a radiating and receiving antenna, the output of which is connected to the corresponding input of a multi-channel receiving device, an identifier for explosives, a centimeter-millimeter radar, a laser module.

In gyro line 32 with NiZn ferrite, by means of a periodic radio pulse generator, using a source of high-voltage nanosecond pulses of the SINUS type (Mesyats GF, Korovin SD, Gunin AV et al. Repetitively pulsed high-current accelerators with transformer charging of forming lines // Laser and Particle Beams. 2003. Vol. 21, No. 2, p. 197-209), high-frequency oscillations (HF) with a power of several hundred MW are excited. HF excitation in nonlinear lines occurs due to instability of the steep front of the shock electromagnetic wave with the HF wave synchronous with it. The front instability is caused by the dispersion of a nonlinear line, which is of two types: spatial (Belyantsev AM, Dubnev AI, Klimin SL, etc. Generation of radio pulses by a shock electromagnetic wave in a transmission line with ferrite // ZhTF. 1995, v. 65 , pp. 132-142) and temporal (Freidman GI On the dependence of the structure of shock waves in two-wire transmission lines on the dispersion characteristic of the system in the linear approximation // Izv. Vuzov. Radiophysics. 1963, v. 6, p. 536- 550).

The possibility of direct effective conversion of a video pulse into a radio pulse was demonstrated for a linear line with spatial dispersion (Seddom N., Spiking C.R., Dolan J.E. RF pulse formation in nonlinear transmission lines // IEEE Pulsed Power Plasma Science Conference. 2007, p. 678-681).

An autonomous mobile self-propelled underwater vehicle contains a propulsion module connected to a navigation and motion control module, which contains an on-board computer, radio and sonar communication modems, a hardware module containing an identifier of explosives in solid and gaseous state, a circular sonar, a seismic measurement unit, multi-beam echo sounder, underwater television equipment, self-contained immersion gamma spectrometer, radar station, speed meters sound, speed and direction of flow, a module for detecting and classifying surface and underwater objects in a protected zone. The adaptive control law, constructed according to the Back stepping method, provides high accuracy of movement along the executive trajectory after almost any lateral deviations.

Underwater television equipment provides low-frame television shooting in black and white and color images of the bottom object with a viewing range of at least 0.7 Zb. Resolution provides the ability to detect an object with a minimum size of 20 mm with a minimum contrast of ≈0.2 s.

Detection and classification of surface and underwater objects, air and ground vehicles, including small-sized marine vehicles of the SONOBOT type, hang gliders and quadrocopters, ground mechanical transport models, in the security zone is carried out by means of a periodic generator containing a source of high-voltage nanosecond pulses, a gyromagnetic line with NiZn ferrite, a high-pass filter, a radiating and receiving antenna, the output of which is connected to the corresponding input of a multi-channel receiving device, P LS centimeter-millimeter range, laser module, GAS.

Meteorological station 38 is an ultrasonic weather station “Weather station” model 200 WX - IP × 7 (AIRMAR Technology Corporation)) - atmospheric pressure, air temperature, wind speed and direction.

Radar 30 is a centimeter-millimeter range station.

In order to demonstrate the distinctive features of the claimed technical solution, in terms of distinguishing features, as an example, not having any restrictive nature, the preferred implementation option is described.

The principle of the system is as follows.

Beacons 24 are located on ice fields 19 drifting with respect to the MNE 23. GLONAS 25 navigation equipment is installed on buoys 24. The antenna GAS 27 is mounted on buoy 23 using a cable cable with suspension 26. Its operation forms a SAC 21 where software 22 is detected moving under ice . The software coordinates, speed, trace are tracked by the relationship of the radio and GA channels and transmitted to the operator of the MNE.

To identify and classify the detected unauthorized software 22, if it appears in the BRZ 28, the high-frequency GAS 27 is installed on the MNP 19, the on-board antennas 29, which are mounted on the MNP 19 housing. coordinates of the onboard high-frequency sonar station 27 or the operator), equipped with a manipulator and a working tool.

The classification of objects using estimates of radial extent has been known for a long time (A. Friedman, “Image of the shape of a body using a sonar or radar system,” Foreign Radio Electronics, 1963, No. 8, pp. 43-64). The mechanism for the formation of a reflected signal from an object with a finite length is considered on page 48 by A.N. Yakovlev, G.P. Kablov "Short-range sonar". - L .: Shipbuilding ,. 1983, where the principles of the formation of the fine structure of the echo signal are given. The envelope amplitude of each echo signal is proportional to the normal area relative to the direction of radiation, therefore, the duration of the echo from the air cavity will be longer than the duration of the echo from the object’s body (t ₂ -t ₁ )> (t ₄ -t ₃ ). Methods for assessing the temporal extent of echo signals are described in detail in a monograph by B.N. Mityashev "Determination of the temporary position of pulses in the presence of interference." - M .: Owls. Radio, 1962

Similar technical solutions are also known for the detection and classification of underwater objects by means of hydroacoustic means: patents RU No. 2460088 C1, 08.27.2012. RU No. 2529441 C1, 09/27/2014. RU No. 2528556 C1, 09/20/2014. RU No. 2465618 C1, 10.27.2012. RU No. 2461020 C1, 09/10/2012. US No. 5438552 A1, 08/01/1995, RU No. 260,2759 C1, 11/20/2016.

Module 20 can be implemented on the basis of a modern universal computer with the ability to work in real time, the ability to switch from one task to another, the presence of flexible addressing to memory, and high data processing speed (Yu.A. Koryakin, S.A. Smirnov, G .V. Yakovlev. Shipborne hydroacoustic equipment, St. Petersburg, publishing house "Nauka", 2004, p. 284) and contains a block for the formation of spectral portraits of unauthorized objects, such as ground vehicles, aircraft, surface and underwater vessels.

The classification of the detected unauthorized underwater object is performed in module 20 according to the signals received from GAS 27, gyromagnetic line 34, underwater television equipment 35, explosive identifier 36, laser module 37, weather station 38. When detecting air objects, use signals received from radar 30.

The base of "spectral portraits" of unauthorized objects is formed in advance with for different speeds of potential unauthorized objects under different weather conditions, taking into account their own interference caused by MCA (units, equipment). At the command of the “detection mode” control, a “spectral portrait” of an unauthorized object detected is received from the “spectral portraits” database. The difference power spectrum (the signal spectrum of the object) is calculated. The difference power spectrum is transmitted to the discrete component detection unit to generate a detection threshold (A.M. Tyurin. Introduction to the theory of statistical methods in hydroacoustic, ed. L., 1963, pp. 127-128). All discrete components that have exceeded the threshold are transmitted to the classification unit to generate classification characteristics from the signal spectrum. The results of classification by spectral features are transmitted to the display and control system unit.

In gyro line 32 with NiZn ferrite, by means of a periodic radio pulse generator, using a source of high-voltage nanosecond pulses of the SINUS type (Mesyats GF, Korovin SD, Gunin AV et al. Repetitively pulsed high-current accelerators with transformer charging of forming lines // Laser and Particle Beams. 2003. Vol. 21, No. 2, p. 197-209), high-frequency oscillations (HF) with a power of several hundred MW are excited. HF excitation in nonlinear lines occurs due to instability of the steep front of the shock electromagnetic wave with the HF wave synchronous with it.

The possibility of direct effective conversion of a video pulse into a radio pulse was demonstrated for a linear line with spatial dispersion (Seddom N., Spiking C.R., Dolan J.E. RF pulse formation in nonlinear transmission lines // IEEE Pulsed Power Plasma Science Conference. 2007, p. 678-681).

TNPA 31 is located in SPU 32, fixed in the form of an underwater box in the underwater part of MNP 19. The SPU mechanisms can be controlled automatically by signals from the onboard GAS 26 or by an operator.

Visual monitoring of individual nodes by the mechanisms of wellhead oil and gas equipment is made in the form of an autonomous underwater television complex.

Meteorological station 36 is an ultrasonic weather station “Weather station” model 200 WX - IP × 7 (AIRMAR Technology Corporation)) - atmospheric pressure, air temperature, wind speed and direction.
