Definitions

  • the invention relates to the field of transport safety and can be used for simultaneous control of a passenger and his baggage to detect prohibited items in baggage, as well as on the body and body of a passenger
  • the device in the form of an x-ray introscope for monitoring luggage (see patent US6269142, class G01N 23/10, 2001), is a conveyor installed in the control zone on which luggage is mounted, while a source is installed above the conveyor X-ray radiation (RI) with a flat fan beam, and a linear X-ray receiver under the conveyor. Scanning an object with a narrow RI fan beam is carried out by moving luggage along the conveyor.

  • the specified image lends itself to contrasting, scaling, underlining contours, coloring objects of different densities in various colors, etc.
  • the main disadvantage of the known device is the inability to use it to control passengers due to the high radiation level of the source, which is necessary for obtaining high-quality images of an X-ray introscope, but is not safe for the passenger
  • X-ray devices with a reduced level of x-ray radiation for example, the device according to patent US7561666, cl. G01N 23/203, 2009., allowing to pass the inspection of a passenger without first removing outer clothing and shoes.
  • the device is a vertically installed cabin in which a source of radiation sources with a flat fan beam and a linear X-ray receiver are installed on synchronously moving lifts.

  • the main disadvantage of the known device is that it searches only a person and not his baggage. Therefore, in addition to such a device, the X-ray introscope described above is usually used to control baggage, and each of the devices used requires its operator to service, who makes a decision on admission passenger or his baggage.
  • the combination of two independent control zones requires not only twice as many experienced operators, but can also lead to the omission of the desired object, because . only general, simultaneously received information about the passenger and his baggage can give the operator an objective assessment of the danger of a given person.
  • Another disadvantage of the known device is that it is practically not suitable for screening disabled people traveling in wheelchairs, since it is impossible to remove the disabled person from the stroller and put it vertically in the cab.
  • the main disadvantage of the known device is that it does not provide the necessary probability of detecting non-metallic objects prohibited from being transported to the protected area, for example, weapons made of non-magnetic materials or forbidden liquids located on the human body.
  • the known device may not be safe for people with implanted pacemakers, because electromagnetic frames and metal detectors of control passages can cause malfunctions in their work.

  • the specified implementation of the passenger screening system allows the passenger to undergo screening control in fairly comfortable conditions, sitting in a chair. In this position, not only good fixation of the body is ensured, which is very important for obtaining high-quality optical and x-ray images, but at the same time the dimensions of the body are significantly reduced, which means that it becomes possible to increase the information content when the dose of x-ray radiation is reduced. Moreover, the passenger You don’t even need to remove outer clothing and shoes beforehand. To go through the screening of a wheelchair user, it is enough to simply transfer him from a stroller to an X-ray transparent chair. In people with implanted pacemakers, X-ray control cannot affect their performance.
