In addition, a delay unit is introduced into the system, and the output of the generator is connected to the input of the detector and the input of the delay unit, the output of which is connected to the input of the detector.

The disadvantage of this system is its highly specialized functional purpose, in particular, it does not have sensors for monitoring other dangerous situations, for example, the transport of dangerous substances and the occurrence of a fire.

A known alarm system according to the patent of the Russian Federation for invention No. 2090934, IPC 6 G08D 13/00, comprising a sensor, a logic unit, a pulse shaper and an alarm shaper.

The disadvantage is also the highly specialized purpose of the system, low reliability and complexity in maintenance.

Known integrated intelligent security system according to the patent of the Russian Federation for the invention No. 2103444, IPC 6 G08D 26/00, decl. 10/06/1994 This system contains the operator’s workstation, controller, alarm module and fire alarm module.

The disadvantage of the system: its highly specialized purpose, the inability to control the operator of the security system and the inability to control the transport of hazardous substances into the room.

These shortcomings were partially eliminated in the system according to the certificate of the Russian Federation for the utility model of Volgaspetsremstroy CJSC No. 21707 Intelligent Integrated Security System, IPC 6 G98B 13/00, publ. 12/28/2001

The disadvantages of the system are the inability to prevent a terrorist attack (an explosion involving terrorists using “suicide bombers”).

The task of creating a utility model that coincides with the technical result is improving the control of persons carrying explosives into the room.

Known automated system for identifying mobile vehicles, monitoring and controlling their movement according to US Pat. RF invention №2113014, which can be used in particular to control the movement of urban transport. The system contains route sensors, a central control room (DPC) with a transceiver and mobile units. The invention allows to organize the simultaneous operation of several dispatchers and radio modem communication with other sources and users of information.

Disadvantages of the system: the use of only radio communication between the object of dispatching and the DAC, which requires obtaining permits for the use of radio frequencies for each newly created system and subsequent significant financial costs for maintaining frequencies. The limited ability to use radio frequencies significantly limits the system capacity and causes the need for specialized, expensive equipment. The system is practically not adapted to prevent terrorist acts, but is intended only to transmit information about technical malfunctions to the central control center.

The disadvantage of this system is that it does not ensure the safety of passengers, especially in cases of terrorist acts or hooligan actions by hackers trying to penetrate the system and does not allow to determine the presence of explosives in the room.

A known system for ensuring the safety of an object according to US Pat. RF for the invention No. 2303818, C1 MCP G08B 21/12, publ. 07/27/2007

This method includes the detection of explosives in the room using at least two sensors for the detection of explosives, with gas analysis instruments installed in them.

This system contains a hardware-software complex with a computer, to which one or several video cameras connected with rotation are connected via a video capture card, one or more microphones connected through a sound capture card to a computer, is characterized in that it contains at least two detection sensors the presence of hazardous substances connected to the computer. Sensors for detecting the presence of a hazardous substance are connected to the computer via a wired or wireless communication line.

The disadvantage is the low accuracy of detection and determination of the presence of explosives in those entering the room and its exact coordinates in plan.

In the context of the present description, "hazardous substances" refers to explosives, poisonous gases and flammable substances.

In crowded places, in particular at airports or at venues for various events, to ensure the safety of passengers or participants in the event, the baggage of passengers or personal belongings of participants in events is usually checked using x-ray machines or metal detectors. In all cases, with the existing possibility of using explosives or other hazardous substances, it is necessary to conduct an appropriate check for the presence or absence of a dangerous substance in a suspicious item (or place) using special verification devices, which, however, are not always available from the person responsible for staff safety. Therefore, when receiving information about the possible presence of explosive or other hazardous substances in a suspicious object (or place), specially trained people are usually called in and directly conduct a check of the suspicious object for the presence or absence of a dangerous substance in it. Such checks for the presence or absence of a hazardous substance in them should be subject to parcels, mail, delivered to the addressee by a special delivery service, as well as suspicious items that are stored in bank safes or mailboxes.

The two most widely known and currently commonly used methods for detecting hazardous substances are the gas chromatographic method and the mass spectrometric method. Both of these methods are based on taking a small amount of gas from a checked parcel (cargo) or a suspicious object for a sample, which is then analyzed for the presence or absence of an element in it that may be part of a hazardous substance, such as an explosive.

The gas chromatographic method for analyzing a sample of gas is as follows. The sampled gas is passed through a silicon dioxide tube with a treated inner surface, a steel tube filled with an adsorbent, or a glass tube heated to the appropriate temperature, after which a carrier gas, such as nitrogen, helium, or hydrogen, is blown through it. The gas sample passing through the tube is divided into individual elements in it, differing from each other by the boiling point or by affinity with the inner surface of the tube or with the filler. Due to the different boiling and affinity temperatures, each element contained in the gas sample passes through the tube at different speeds and exits the tube at different rates. In gas chromatographic analysis of the gas, the thermal conductivity of the individual elements contained in the gas is essentially measured and the composition of the gas is determined with an analysis of the elements contained in it.

The presence of TNT and RDX in a gas, which are commonly used as explosives, is determined by the content of nitrogen dioxide (NO ₂ ), which is the main element of explosives. However, nitrogen dioxide is only one of the elements contained in the explosive, and it is quite difficult to determine the structure of the compound by its content in the gas. Therefore, with this method of analysis, relevant reference or regulatory data are usually obtained in advance, with which the data obtained during the analysis of the gas sample taken are compared, and based on this comparison, it is concluded whether the substance being tested is explosive or not, and if the analysis results are positive identify the type of explosive. This procedure, based on several measurements, usually takes several minutes. In addition, this method of detecting explosives requires constant maintenance of the equipment and obtaining regulatory data necessary for comparative analysis.

During mass spectrometric analysis, the sampled gas is ionized and the mass of the ion (in particular m / z, which is obtained by dividing the mass m by the electric charge z of the ion) is measured using a vacuum mass spectrometer. The mass spectrometers used in this method of gas analysis are divided into two types: quadrupole mass spectrometers and ion trap mass spectrometers.

A quadrupole mass spectrometer is a mass spectrometer that contains four rod electrodes, around each of which, when a DC voltage is applied to it, on which a high frequency voltage is applied, an electric field is created. The electric field created by the electrode attracts ionized molecules of the sampled gas. Ions entering the electric field undergo complex spatial oscillations, and as a result, only those ions pass through the field, and then they are fixed, in which the mass to charge ratio (m / z) corresponds to the DC voltage and high frequency voltage supplied to the electrodes. Other ions collide with one of the electrodes and discharge. Maintaining at a constant level the ratio of DC voltage to high frequency voltage and continuously scanning ions, it is possible to obtain the spectral composition of the analyzed gas sample.

An ion-trap mass spectrometer contains two end electrodes made in the form of caps and one electrode made in the form of a ring. When ionized molecules of a sampled gas fall into the zone between these three electrodes, the ions are held (i.e. captured) by an electric field that is created by a high frequency voltage applied to the ring electrode. As a result of scanning the ions with another high-frequency field, which is fed to the end electrodes, the captured ions are released that have the corresponding mass. By detecting the released ions using an appropriate sensing element, the spectral composition of the sampled gas can be obtained. Ions are in an electric field and are released from it after a certain period of time (of the order of several dozen ms). Thanks to this averaging, the sensitivity of the mass spectrometer reaches an extremely high level.

By analyzing the data obtained in the manner described above on the mass spectrum of the gas sampled, it is possible to determine the presence in the spectrum of components characteristic of hazardous substances, in particular explosives, which may be in the item being checked. In this case, it is possible not only to determine the presence or absence of a hazardous substance, in particular explosive, in the gas sample, but also, if necessary, to identify the type of hazardous substance detected as a result of the analysis of the gas sample. This verification method allows you to establish the presence of a dangerous substance in the item being checked and identify it within a few seconds (usually from 3 to 8 seconds). It should also be noted the high reliability of the mass spectrometric method of analysis, which can be further enhanced by conducting sequential or multi-stage analyzes by first performing spectral analysis of the mass of ions extracted from the entire mixture of ions and characteristic of explosives (mother ion), and the subsequent activation of mother ions and masses - spectral analysis of fragmented ions (daughter ion) formed from parent ions.

Despite the fact that the need for the detection of hazardous substances exists when checking personal items at airports or at various events, and when delivering parcels or mail to the addressee by the delivery service and when checking suspicious items stored in a bank safe or in a mailbox Nevertheless, a method for detecting hazardous substances common to all these cases still does not exist. This is probably due to the following reasons.

1. The problem associated with the time necessary for the verification.

Usually personal belongings or baggage of passengers are checked during their movement on a conveyor belt. If the personal belongings or baggage of passengers are checked for too long for the possible presence of explosives in the inspection area, a very large number of people can accumulate. To avoid this, the entire test procedure at a normal conveyor speed (equal to 12 m / s) should take only a few seconds (for example, 8 s). It is for this reason that in such situations it is impossible to use the gas chromatographic method, in which considerable time is required to carry out the necessary analyzes. Therefore, to check objects moving along the conveyor belt, it is more advisable to use the mass spectrometric method of analysis, in which the entire procedure of checking and detecting a dangerous (explosive) substance in the tested object takes only a few seconds and allows you to get fairly reliable results.

2. The problems of training specialists with knowledge in a particular field of technology.

For effective checking at airports of personal belongings or baggage of passengers for the presence of dangerous, in particular explosive, substances, the inspection area should be equipped with a large number of different devices. To work with such devices, for their maintenance, inspection, repair, readjustment or replacement among airport employees, it is necessary to have people trained for such work who have special knowledge in a certain field of technology.

3. Protection against possible explosion.

If explosives are found in baggage, certain precautions must be taken to protect people from the consequences of a possible explosion. Usually in such a situation, the airport administration immediately calls by telephone to the appropriate services (the police or the fire station) for help and calls a special team that can work with explosives. At the same time, the airport administration itself must take special precautions, which depend on the type of explosive detected, its quantity and shape, as well as on the container in which it is located. Obviously, obtaining accurate information about the detected explosive prior to arrival at the place of the called group of specialists should help the airport administration in time to take appropriate precautions. Moreover, it is highly desirable that such precautions be taken immediately after the discovery (in the baggage or personal belongings of passengers) of an explosive substance.

Also known is the airport security system according to the patent of the Russian Federation

No. 2236041, publ. 02/10/2004, the prototype.

This system contains a metal detector and a device for determining the presence of a hazardous substance, made in the form of a device for sampling, with a sampling tube mounted on a baggage conveyor, which takes air surrounding the baggage along with all the gases contained in it, a mass spectrometer designed for the analysis of gas taken for verification by a sampling device, a communication device, for example, a modem that transmits and receives information via a communication line, a display designed to display information , and a control device for all of the above devices, made, for example, in the form of a personal computer, while connected to a remote computer through a communication device (modem) and communication line with a remote computer for transmitting mass spectrometric analysis of samples obtained using masses spectrometer, in-line communication

The disadvantage of the system is that it does not provide effective detection of hazardous substances, because focused on his search in baggage. In fact, it is possible for the hazardous substance to be transported by visitors (passengers and meeting people) through the entrance to the premises or by other methods not known beforehand, for example, through an office building. Installing a large number of hazardous substance detection devices in all rooms is unrealistic due to the high cost.

The tasks of creating a utility model is to increase the reliability of detection of a hazardous substance and determine its location in terms of space at minimal cost.

The solution of these problems was achieved in the airport security system, containing a metal detector and a hazardous substance detection device made in the form of series-connected air intake tubes, an air sampling device, an air pumping device, an air supply pipe, a mass spectrometer and an air discharge pipe, mounted on a conveyor for moving luggage, a communication device, for example, a modem that transmits and receives information on a communication line, a monitor designed to the presentation of information, and a computer, while a remote computer is connected to the computer via a communication device and a communication line for transmitting mass spectrometric analysis data of a sample obtained using a mass spectrometer to a communication line, characterized in that at least three detection devices are used hazardous substance, in this case, the second device has an intake pipe installed in the frame of the metal detector, and the other devices have intake pipes installed in the room. To determine the hazardous substance in the room, one hazardous substance detection device was used, to which several air intake tubes mounted in different parts of the room are connected through a multi-way valve, while the multi-way valve has the ability to periodically switch all air intake tubes in turn, connecting them to the detection device hazardous substance. The system may include a baggage weighing device and an X-ray device that allows you to obtain an X-ray image of it, and when this information about a hazardous substance is detected in the item being checked, the control device receives information about the weight of the item being checked from the measuring device, and its X-ray image from the X-ray device which are transmitted by the control device through the communication device to the communication line, and then transmitted to the monitor is transmitted to the monitor Maemo device connection instruction with a list of precautions that should be taken in connection with the discovery in the checked luggage of the dangerous substance. A video surveillance system containing surveillance cameras is connected to the computer using communications equipment. A thermal imaging video surveillance system comprising at least one thermal imager is connected to the computer using communication means.

Fig.8 shows a system with a backup power source of electricity,

figure 9 shows a diagram of a system of additional equipment with an x-ray apparatus and a baggage weighing device.

The system (figure 1 ... 9) is designed to detect in the room 1 explosive 2 (and other hazardous substances) using several devices 3, 4 and 5 .. According to the invention of devices should be at least 3. At the same time, devices 3, 4 and 5 contain air sampling tubes 6. Room 1 has a metal detector 8 installed at the inlet 7 and a guard 9 between them. In room 1, a conveyor 10 with a drive 11 is installed, designed to issue (receive) baggage 12.

A feature of the system according to the invention is that the air sampling tubes 6 are installed for the first device 3 near the conveyor 10 against the baggage 12, as close as possible to it, the air sampling tube 6 of the second device 5 is installed (built into the metal detector 8, to control the presence of hazardous substances in passing In addition, at least one device 5 is intended only to control the presence of a hazardous substance in room 1 and contains at least two air sampling tubes 6, in a specific example, four air sampling tubes are used spirit 6 installed in the corners of room 1 and connected by transport pipelines 13 to the inputs (four in this example) of a multi-way valve 14, the output of which is connected to the device 5. This is necessary because of the very high cost of the device 5 and because the concentration hazardous substance 2 decreases in direct proportion to the cube of the distance from it, and modern devices capture the concentration at a distance of up to 60 m. The number of air sampling tubes 6 also cannot be very large (tens and hundreds) due to the length of the gas analysis process behind.

It is preferable to use all devices 3, 4 and 5 of the same type. It is possible that only one of them, namely, device 5, designed to determine the presence of a hazardous substance in room 1, is used in a special version, i.e. able to work in two modes: the detection mode of a hazardous substance and the mode of determining its concentration. This will allow, having readings at least at two points, to calculate with a computer the position of the hazardous substance 2 in terms of room 1.

The system contains the operator’s workstation 15, which, in turn, contains a computer 16, a monitor 17, a manipulator 18 (a mouse or joystick type) webcam 19. All connections are made by communication channels 20. Communication channels 20 can be wired or wireless, for example, a radio channel. There can be several operator jobs 15, then the corresponding number of computers will be used 16. Computer 16 (more precisely, a Pentium type system unit with installed Windows-XP OS) is designed for general manual and automatic control of the entire system, turning the camera towards explosive, calculations of its concentration and other actions. A digital video surveillance module 21, which contains video cameras 22 (preferably digital video cameras), is connected to a computer 16 via communication channels 20, and a thermal imaging video module 23, which contains at least one thermal imager 24 connected by communication channels 20 to a computer, can also be connected to a computer 16 16. The system includes several hazardous substance detection devices 3, 4 and 5. At least one hazardous substance intake pipe 6 is installed in the corners of room 1. Due to the high cost of the devices, it is detected zheniya dangerous substance 3, 4 and 5, the number in the room is limited. In addition, according to the invention, the Internet 26 is connected to the computer 16 through the modem 25 (Fig. 3) for control and monitoring from a remote computer (the remote computer is not shown in Figs. 1 ... 9.)

Devices for the detection of dangerous substances 3 ... 5 are designed to detect this substance, its identification, and, if necessary, determine its concentration (figures 1 and 2) at the installation site. The concentration of explosive 2 at any point is determined by calculation and using computer 16 and using the algorithm below determines the location of explosive 2 in terms of room 1.

Figure 4 shows a diagram of a device for detecting a dangerous substance 5. Devices for detecting a dangerous substance 3 and 4 can also be performed according to the same scheme. The hazardous substance detection device 5 contains a series connected air intake pipe 6, an air sampling device 27, an air pumping device 28 (compressor), an air supply pipe 29, a mass spectrometer 30, an air discharge pipe 31. The mass spectrometer 30 is connected in series the controller 32 and the device negotiation protocols 33 connected to the communication channel 20 to the computer 16

The mass spectrometer 30, in turn (Fig. 5), contains a series-connected operating mode switch 34 (three-way valve), a mode switch 35 drive mechanically connected to the mode switch 34. Two gas analyzers are connected to the output of the operating mode switch 34: a recognition device hazardous substance 36 and a device for measuring the concentration of dangerous substance 37. The drive of the operating mode switch 35 and devices 36 and 37 are connected by a communication channel 20 to the controller 32, which, in turn, through the protocol matching device 33 connected to computer 16 for transmitting result information via RS 232 protocol.

The results of measuring the concentration of explosives in the air are illustrated in Fig.6 and 7 by curves 38, 39, 40 and 41).

Fig. 8 shows a diagram of a system with a backup power supply. In the system, computer 16 is connected to the network 44 via an uninterruptible power supply 43 through an uninterruptible power supply 43. In addition, a backup power supply 45 is connected via a switch 47 to an uninterruptible power supply 43 for providing power to the electrical energy system in the absence of it in the network 44.

Figure 9 shows that the system can optionally be equipped with a baggage weight detection sensor 48 and an x-ray unit 49.

It is possible to connect to the system, more precisely, the computer 16 through the weapon controller 50, at least one unit of the remotely controlled small arms 51 (FIGS. 10 and 11). The structural diagram of the unit of the remotely controlled small arms 51 is shown in FIG. 11.

Each unit of the remote-controlled small arms 51 contains (11) a vertical movement drive 52, a horizontal movement drive 53, a trigger mechanism 54, an optical sight 55, a guidance video camera 56, a laser target indicator 57 mounted or connected to a barrel 58 that is mounted on platform 59 with the help of a hinge 60. The weapon controller 50 is connected by electrical connections 20 to the actuators 53 and 54, with an optical sight 55, a guidance video camera 56 and a laser target designator 57. The security and defense system includes a a distributor of a high-pressure working fluid 61, which is connected by a pipe 62 to a source of a high-pressure working fluid 63. The output from the distributor of a high-pressure working fluid 61 is connected by two high-pressure pipes 64 to a drive 56. The weapon controller 50 is connected by a communication channel 20 to the drives 53 and 54. Each unit of remotely controlled small arms 51 is controlled by a mouse-type manipulator 18 (FIG. 1).

It is possible to install a unit of remote-controlled small arms 51 on the ceiling 65 (FIGS. 10 and 11) with the possibility of horizontal movement by means of a drive 66 with a kinematic mechanism 67 along rails 68. A position sensor is used to accurately monitor the position of the unit of remote-controlled small arms 51 69 mounted on the ceiling 65 and connected to the kinematic mechanism 68 and the sensor of the global remote positioning system 70, for example, Glonas, installed on the basis of 71 units of remote control th small arms 51. The base 70 is mounted on rails 68 via roller bearings 72. Unit remotely operated small arms 51 is protected and disguised protective cap 73 streamlined. The simultaneous use of the position sensor 69 and the sensor of the system of the global remote positioning 70 increases the reliability of the system in case of failure of one of these sensors. In addition, if a remote-controlled small-arms weapon 51 has an optical sight 55 and a surveillance camera 56 fail, computer 16 will calculate with sufficient accuracy the position of the dangerous substance or suicide bomber using data on the concentration of the dangerous substance from less than four points in which are placed air sampling tubes 6 and from surveillance cameras 22, and at night with the lights off, additionally from thermal imagers 24.

A review of Russian and foreign devices (sensors) designed to detect hazardous substances based on gas analysis is described in the book “Detection of explosives using gas analysis equipment”, Ministry of Internal Affairs, Siberian Branch of the Scientific and Production Association “Special Technique and Communication”, Novosibirsk, 2001 This book provides an overview of devices designed not only for the detection of explosives, but also poisonous, narcotic and generally any organic substances based on gas analysis of the environment. Such devices make it possible to determine the presence of vapors of a hazardous substance at a distance of up to 60 m for 10 ... 60 sec. The disadvantages of these devices are their high weight and high cost. The relatively large weight is not an obstacle to the use of stationary devices for the detection of hazardous substances based on gas analysis. Scientific research to improve and mass production of such devices will reduce their cost by an order of magnitude and make them available for use at all objects of mass crowding: at airports, train stations and on vehicles and airplanes.

Systems are managed using a software product developed by Integra C.

The software is supplied complete with video cameras and was developed by Volgaspetsremstroy CJSC, which is part of the INTEGRA-S Consortium.

Before working on computer 16 (Figs. 1 and 2), the operating system and software are installed: a program for processing video images coming from video cameras 22 installed on objects and from a thermal imager (thermal imagers) 24 (if any). At the same time, from several sensors for the presence of explosives 5, information enters the computer 16.

In this case, air is pumped through the hazardous substance detection devices 3, 4, and 5, which passes through the mass spectrometer 30 (FIGS. 3 and 4). When dangerous substance 2 is detected, the signal from the mass spectrometer is sent to controller 32, then to the exchange protocol matching device 33, and then to computer 16. Information from several hazardous substance detection devices 3, 4, and 5 is received on computer 16. When a dangerous substance is detected, the computer 16 sends a command through the protocol negotiation device 33 and the controller 32 to the mass spectrometer 30 to switch the mode. Prior to this, the mass spectrometer 30 worked in the "Detection" mode. At the same time, he not only detected a dangerous substance, but also made its identification using a hazardous substance recognition device 5, in which a spectral analysis of the selected air was carried out and spectra were compared with standard spectra for hazardous substances (explosives, drugs, etc.) using computer 16

After the detection of a hazardous substance, the computer 16 sends a signal to the drive of the mode switch 35 and the mode switch 34 drives the hazardous substance detection device 5 to the mode for determining its concentration. Comparison of the concentration of hazardous substance 2 obtained from all air sampling tubes 6 of the hazardous substance detection device 5 allows you to determine its location in terms of room 1 with an accuracy of 0.01 m (Fig.6 and 7).

If necessary, use (Fig. 9) a baggage weight detection sensor 48 and an X-ray unit 49 installed behind the metal detector 8 along the course of visitors to the airport premises 1.

If necessary, to destroy the suicide bomber, the guidance of a unit of remote-controlled small arms 51 is carried out by computer 16 manually using the image on the monitor 17 or automatically using guidance programs and drives 52 and 53. The shooting command is sent to drive 54 from the manipulator 18 or from computer 16 without operator intervention, depending on the source data ..

Application of the utility model will allow:

1. Constantly monitor the situation at the facility in order to obtain timely information about the unlawful actions of a suicide bomber trying to bring explosives into the airport premises (for example, a waiting room).

2. To detect hazardous substances (poisonous gases, explosive and narcotic substances) at objects of mass crowding both in baggage and under clothing passing into the airport premises, and in the airport premises ..
