Description

The invention relates to the field of control of vehicles moving on their own and can be used for inspection in order to detect hidden objects, substances and materials that are prohibited for transportation.

Known (RU, patent 2463664, publ. 2012) is an airport security system comprising a metal detector and a hazardous substance detection device made in the form of a series-connected air intake pipe, an air sampling device, an air pumping device, an air supply pipe, a mass spectrometer and an air discharge pipe mounted on a baggage conveyor, a communication device that transmits and receives information via a communication line, a monitor designed to display information and a computer, and a remote computer is connected to the computer through the communication device and the communication line to transfer mass spectrometric analysis data of the sample obtained using the mass spectrometer to the communication line. When implementing the system, at least three devices for detecting dangerous substances were used, while the second device has an intake pipe installed in the frame of the metal detector, and the rest of the devices have intake pipes installed in the room, and one device of a dangerous substance was used to determine the dangerous substance in the room, to which several air intake pipes mounted in different parts of the room are connected through a multi-input valve, while the multi-way valve has the ability to periodically switch over all air intake tubes are connected, connecting them to a hazardous substance detection device.

A disadvantage of the known system should be recognized as its fundamental unsuitability for use on moving objects.

Known (RU, patent 90390, publ. 2010) is a multifunctional on-board information system for a passenger carriage of a railway transport, containing a security system located in each carriage, nodes for connecting to external communication networks, communication devices for passenger seats in the carriage and a power supply. In addition, it introduced a multiservice network controller in the form of an unattended computer in a protective case, to which a security system, nodes for connecting to external communication networks, terminal devices for connecting passenger seats in a car and a power supply are connected. The system may also contain a video surveillance camera and smoke, movement and increased vibration sensors, as well as sensors of the "Electronic nose" type for detecting substances that are prohibited for transportation.

A disadvantage of the known system should be recognized as a narrow scope - a railway passenger car. The closest analogue of the developed invention can be recognized (US patent 7005982, publ. 2006) a method for monitoring a vehicle for the presence of prohibited substances and goods, characterized in that a device containing at least one sample concentrator is placed in the vehicle’s volume for analysis, a GPS navigator, a microprocessor and a radio transmitter connected to the navigator and a microprocessor, while the device is made with the possibility of fixing inside the vehicle, after holding for of time sufficient for a reliable sample collecting concentrator information about the impurities present in the atmosphere, the volume of the vehicle, the apparatus for transmitting content analysis prohibited cargo and analyzed adsorbed impurities hub.

A disadvantage of the known device should be recognized as the lack of control over the set of samples, which allows to block access to the concentrator, which distorts the results of the control.

The technical problem solved by the developed method is to provide complete control over transportation by land, air, river and sea transport.

The technical result achieved by the implementation of the developed method consists in increasing the reliability of monitoring while expanding the scope of its application.

To achieve the specified technical result, it is proposed to use the developed method for monitoring a vehicle for the presence of goods prohibited for transportation.

According to the developed method, a device is placed in the vehicle’s volume, comprising at least one sample concentrator for analysis, a GPS / GLONASS navigator, a microprocessor and a radio transmitter connected to the navigator and a microprocessor, the device further comprising a video camera connected to the radio transmitter and microprocessor, directed to the input of the concentrator of samples, the device is made with the possibility of fixing inside the vehicle, after holding for a time sufficient o for reliable collection by the concentrator of a sample of information on impurities present in the atmosphere of the vehicle volume, the device is transferred for analysis for the content of goods prohibited for transportation and the impurities adsorbed by the concentrator are analyzed.

The developed method is based on the principle of concentration of controlled impurities on a material carrier (preferably a sorbent) with their subsequent analysis on stationary analytical equipment. The sample concentrator, which in the basic version is a flowing container filled with a sorbent, to which a motive agent for air movement through the container is attached, is placed in the cavity of the vehicle in which cargo prohibited for transportation (explosives, narcotic substances, etc.) can be placed . A sufficient amount of air in the vehicle cavity is passed through the sample concentrator so that a sufficient amount of impurities in the air is adsorbed in the sample concentrator for analysis. For fixing in the volume of the cavity of the vehicle (inside the railway carriage, cargo and / or passenger compartment of the aircraft, body and / or passenger compartment, hold of the craft), the device contains a locking element of any acceptable design that provides reliable fixation of the device in the volume of the cavity. The GPS / GLONASS navigator included in the device, a microprocessor and a radio transmitter connected to the navigator and microprocessor provide control by the dispatch service by periodically supplying radio signals about the location of the device, and the microprocessor sets the frequency of the radio signal supply, as well as by the service that controls the transportation of prohibited substances throughout the country , for the location of the device and, if there is a similar navigator with a transmitter installed on the vehicle, do not delete but if the device is out of the scope of the vehicle. The device as a whole can be connected to the vehicle’s electrical system, but it can also contain an integrated power source, including a renewable power source. Preferably, each device is assigned an individual number, the value of which is included in the text of the radio signal, which allows you to track the location of each device in automatic mode. For greater reliability of sample collection, the device contains a video camera directed to the input of the sample concentrator. This will exclude the possibility of unscrupulous carriers to replace pumping through the concentrator of air from the volume of the cavity of the vehicle to the supply of concentrator that does not contain any impurities from the cylinder, since a signal from the video camera will be added to the radio signal about the location of the device, showing where the device is located and how it works.

After removing the sample concentrator from the vehicle’s volume, it is transferred for instrumental analysis (preferably chromatographic or spectral) to the units of the structure that controls the transportation of prohibited substances throughout the country.

For greater reliability of sample collection, it is desirable to install the device in the exhaust ventilation system of the vehicle cavity. In this case, the volume of air from the cavity of the vehicle passing through the hub will be increased.

In the future, the essence of the developed technical solution will be disclosed using implementation examples.

A modified gas impurity concentrator, commercially available for gas chromatographs of the GC-2010 series, containing several sorbing columns, was used as a sample concentrator. The concentrator was additionally equipped with a GLONASS navigator and a radio transmitter. The hub pump and the radio transmitter were connected to the connection block to the vehicle circuitry. The mount was made mechanical (clamps).

The sample concentrator was mounted on a rack of a closed truck body of the KUNG type truck. 400 grams of trinitrotoluene, 500 grams of HMX and 800 grams of ammonal were placed in the body. The car drove along the highway at an average speed of 70 km / h for 2.5 hours. Then the concentrator was removed from the body and transferred to the chromatographic analysis of the adsorbed impurities using a gas chromatograph of the GC2010 series, and the person making the analysis was not familiar with the composition of the impurities. According to the results of the analysis, the presence of trinitrotoluene, octogen and ammonal in the body was qualitatively determined.

The sample concentrator was installed at the exhaust ventilation outlet of a reserved seat passenger car. 1000 grams of poppy straw, 400 grams of heroin and 400 grams of amphitamine were placed in a breathable package. The passenger car used was part of the Moscow-Vologda train. After about 4 hours in Yaroslavl, the concentrator was removed from the car and transferred for analysis. According to the results of the analysis, the presence of poppy straw, heroin and amphitamine in the car was determined.

The sample concentrator was installed in the hold of the St. Petersburg - Kaliningrad ferry. In the hold placed samples of ammonal, tetryl and trinitrotoluene in an amount of 1000 grams. After 36 hours, the concentrator was removed from the hold and submitted for analysis. The presence of ammonal, tetryl and trinitrotoluene was determined chromatographically.

Samples of narcotic drugs (heroin, cocaine, marijuana) in the amount of 400 grams were placed in the passenger cabin of the TU-154 aircraft. The plane made a flight Moscow - Mineralnye Vody. At the end of the flight, the concentrator was removed and the content of adsorbed impurities was checked on a Sapsan-1 mass spectrometer. The result of the study was the detection of heroin, cocaine and marijuana in the cabin.
