Description

The invention relates to the field of burglar alarm, in particular to means of monitoring a protected area, intended for the detection and identification with the help of technical means of objects penetrating the protected area and causing the operation of technical means of detection when moving objects in the protected area.

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 information transmission system (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 “Security system of the perimeter“ Radioveb ”is known, described in the patent for utility model RU No. 129283, IPC G08B 25/00, publ. 2013. The system contains a block of detection tools and a block for collecting and displaying information. The block of detection means 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 essential 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, IPC G08B 13/19, publ. 2011. The complex contains a control center, 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 receiver of a two-position radio-beam detection means, passive infrared detection means, a thermal imager and a detector for detecting the intruder's proximity to the local security 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 performed, targeting of the optoelectronic devices of a three-dimensional circular review and accompaniment 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 complex are:

1) the absence in the complex of two-way radio communication between the control center and other 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 other, closest in technical essence to the claimed invention, known system "Intelligent sensor network (Intelligent Sensor Network), described in US patent No. 8710983, IPC G08B 1/08, G08B 13/00, H04W 4 / 00 publ. 2014, which is selected as a prototype. 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 a peer-to-peer radio network, in which information is transmitted by selecting routes according to the criterion of the best quality of radio communications. 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 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 point) and a group of nodes of a network of sensors (technical means of detection); included in the gateway (central control center) - 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, configured to receive and transmit information between a gateway (central control center) and a group of nodes of a network of sensors (detection equipment) connected to each other in a peer-to-peer 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 aim of the present invention is to provide the ability 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 specified goal is achieved by:

1) the use of small-frame video surveillance systems made with the possibility of highlighting pre-alarming, alarming and post-alarming video information for reliable visual identification of detected objects;

2) separation of radio communication channels by frequencies for transmission to the central control point of alarm messages from technical means of detection and video information from technical means of video surveillance;

3) providing with technical means of detection and video surveillance technical means of relaying transmitted messages to a central control center;

4) 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.

The goal has been achieved in the proposed “Intelligent Network System for Monitoring the Protected Area”, which contains a central control center and a group of detection equipment, the central control center includes the first radio modem operating on the radio frequency of the first radio channel, a communication module with the ability to communicate with external devices with using a network interface and a personal electronic computer with a graphic monitor, each hardware of detection 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 means detection, which are interconnected in the first peer-to-peer radio network operating on the radio frequency of the first radio channel and configured to automatically re-route In order to transmit information 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 capable of highlighting pre-alarming, alarming and post-alarming video information, each video surveillance equipment containing a second radio modem operating on the radio frequency of the second radio channel to transmit video information to the central control center, in which to receive video information supplement The second radio modem is included, the group of video surveillance equipment and the central control center are interconnected into a second peer-to-peer radio network operating on the radio frequency of the second radio channel and configured to automatically reconfigure information transfer routes according to the criterion of the best radio quality.

Alarm sensors included in the technical means of detection, made with the possibility of functioning in the form of:

1) seismic alarm sensors with classification of the intruder ("single", "group", "vehicle") and determination of the direction of movement ("to us", "from us");

2) radio wave alarm sensors for work on terrain with complex terrain;

3) passive infrared alarm sensors;

4) magnetometric sensors of alarm with the determination of the presence of a metal weapon in the offender (“armed” or “not armed”);

5) one-position or two-position radio-beam alarm sensors;

6) 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 the 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 designed as an operator’s workstation, which is provided with archive memory, an alarm 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 exposure and video information coming from technical means of video surveillance.

The invention is illustrated in FIG. 1-2, which depict the following.

In FIG. 1 shows an example of a structural diagram of a system for monitoring the perimeter of a guarded object.

In FIG. 2 shows an example of the location of the detection and video surveillance zones of the system as applied to the perimeter shown in FIG. one.

In FIG. 1-2 designations are introduced: the central control center (CPU) - 1, the technical detection tool (TCO) - 2, the first radio modem - 3, the personal electronic computer (PC) - 4, the graphic monitor - 5, the activity detection module - 6 , processor - 7, memory module - 8, alarm sensor - 9, first radio channel - 10, video surveillance equipment (TSV) - 11, second radio modem - 12, second radio channel - 13, communication module - 14, network interface - 15, human-intruder - 16, detection zone of the radio-beam sensor - 17, for observations - 18. The dashed line, for example, in FIG. 1 indicates the perimeter of the protected object. The CPU and communication channels of FIG. 2 are not shown. The intruder shown in FIG. 1-2, conditionally penetrates the protected area in the direction indicated by the arrow. One of TCO 2 in FIG. 1 (in the lower right corner) is depicted on a larger scale to show its components. TCO power supplies in FIG. 1-2 are not shown.

The proposed system (Fig. 1) works as follows.

The system monitors the protected area in an open area. In FIG. Figure 1 shows an example of the location of five TCO 2 and six TSV 11 in the protected area. The TCO are connected to each other and to the CPU 1 through the first radio channel 10, forming the first peer-to-peer 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 peer-to-peer 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, selected as a prototype for the proposed technical solution. 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 a PC 4 with a graphic monitor 5. TCO 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 post-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 peer-to-peer radio networks used are self-organizing and are configured to automatically reorganize 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. In FIG. 2 shows the detection zones of the radio-beam sensors 17 formed by the TSO and the observation zones 18 formed by the TSW. Zones 17 are shown as ellipses, and zones 18 are shown as shaded triangular sectors.

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 advancement of a person-offender 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 promotion of the person-violator in the monitoring zone, indicating the numbers (addresses) of the TCO, the time moments of the crossing of the detection zones by him, and also captures video information on his progress.

Each TCO 2 includes the first radio modem 3, activity detection module 6, processor 7 with memory module 8, a power source (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 routes for transmitting information to the CPU 1. The memory module 8 is designed to store the 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 operation are possible.

TCOs can be configured to detect a human-intruder, 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). To create quickly deployable places of temporary basing of people, vehicles, material assets on extended flat 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 trails, 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 for 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 of the detected 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 operating 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 the radio-beam sensors of the alarm system of the ERMO 482X PRO series manufactured 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.-№3 (23). - from. 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 peer-to-peer radio networks.

In the monitoring zone, video monitoring points of a low-frame mobile video surveillance system, which are described in RU patent 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, the video cameras of these video monitoring points are turned on with the CPU, 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. For example, in FIG. 2 vertical observation zones 18 are directed in one direction, and horizontal - in different directions.

In the proposed 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 proposed 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 post-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.

PC 4, which is part of CPU 1, is designed as an automated workstation (AWP) for the operator, 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 TSV 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.

Weather conditions are provided by obtaining the necessary information from an external weather station.

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

Additional features introduced into the known system make it possible to give the proposed system new significant properties.
