Description

Security lock cabin in access control and management systems (ACS).

The utility model relates to alarm systems and can be used to ensure security during the inspection of visitors to public institutions and buildings, passengers at transport infrastructure facilities, as well as at other controlled facilities.

When describing and analyzing the nature of the prototypes of the claimed utility model, some electromagnetic and structural features are not taken into account that are not related to ensuring the security of the person being searched when a person passes through the cabin, but the disadvantages that cause structural and functional limitations to ensure such safety or the quality of the result are considered.

Known patent 2371735 10/22/2004 "DETECTION OF A HIDDEN OBJECT" for a method and device, the essence of which is as follows:

- in one embodiment, during the scanning process, the antenna arrays are rotated through an angle of 240 degrees in total or 120 degrees for each antenna array (see FIG. 12 of patent 2371735). Thus, due to the limited angle of rotation of the gratings, free space is formed for the organization of openings for entry and exit.

- in another embodiment, the antenna arrays are motionless, but the person being inspected becomes on a rotatable platform that rotates through an angle of 360 degrees (see Fig. 1 of patent 2371735).

The disadvantages of this method and device design are:

1) The rotation of a person on a moving platform in one of the ways can lead to loss of balance and fall, which is unsafe for the inspected.

2) Inevitably blurring the image in small details, since the rotation of a living person is necessarily accompanied by a change in its position relative to the axis of rotation of the turntable and the exposure time for scanning purposes is long, because rapid rotation is not possible to avoid accidents and complete loss of balance.

3) The use of a fixed platform, but with a limited angle of rotation of the antenna arrays of 240 degrees, to provide openings for entry and exit, as a result of scanning when moving the antenna arrays, it leaves “blind spots” on the side of the openings or is accompanied by a significant degradation in the quality of scanning on the part of these openings.

The well-known "Complex for detecting objects hidden under clothes on the human body" (utility model patent No. 95130 IPC G01N 22/00 op. March 30, 2010). The complex consists of receiving and transmitting antennas, respectively connected to a receiver and transmitter of signals that are connected to a reference generator, while the signal receiver is connected to an analog-to-digital converter (ADC), which is connected to a signal processing device, with N> 2 antennas are assembled in the form of two vertical and symmetrically arranged relative to a person antenna arrays installed with the possibility of moving around a person, each of the antennas connected through a switch to respectively ISRC and the transmitter signals and the signal processing unit is connected with a control channel transmitter, a receiver, and the mechanism for moving the switches antennas. To irradiate the person being examined, the transmitter generates a broadband linearly frequency-modulated probe signal, which, through the transmitting switch, enters the corresponding antenna, which is selected using the switch by the signal from the signal processing device. The signal reflected from the object is received by the corresponding receiving antenna and enters the switch, the choice of the working channel of which is made according to the signal received from the signal processing device. When the rotary device is rotated, the pairs of receiving and transmitting antennas are sequentially switched and the received signal is accumulated from all points of space formed vertically by switching the antennas horizontally by rotating the antennas. The signal processing device processes the information received from the analog-to-digital converter using a neural network classifier, decides on the presence or absence of hidden objects on the human body and displays the result of detection.

The disadvantage of this device is that when moving the antenna arrays around a person, a danger is created by the movement of the antenna arrays if the rotation occurs at an angle greater than or equal to 330 degrees, since the path of entry and / or exit may intersect with the path of the antenna arrays.

The well-known "Search complex and method for detecting items prohibited from moving through checkpoints" (application for invention No. 201015398/08, IPC G08B13 / 18 04/20/2010) containing a metal detector and operator’s workstation with a monitor to obtain information about the detection of prohibited items containing two guarded control devices, one of which is located at the entrance to the inspection area, and the second at the exit from it, at the entrance to the inspection area, an explosive detector is placed, two television cameras are installed inside the inspection area s for photo-verification of the identity, one aimed at the entrance and the other at the exit from the inspection area, and a combination device including a metal detector and a detector of radioactive and nuclear materials, while both guided devices, an explosive detector, a combined device and television cameras are connected by a trunk line with an access control and management system that, in accordance with a predetermined algorithm, blocks a person with prohibited items inside the inspection area and displays an alarm information on the monitor screen of the operator’s workplace.

The disadvantages of this device is that the use of only two blocking control devices does not allow the use of a modern radio wave scanning system with antenna arrays (for example, described in patent N 95130 "Complex for detecting objects hidden under clothing on the human body" IPC G01N 22/00 op. 30.03 .2010 d), the functioning of which is associated with the rotational movement of these gratings around the person being searched due to the danger that arises or for the person being searched when the gratings move inside anstva limited barring devices managed, either because there is a danger for the staff when the grids are moving outside the space defined by barring devices manageable.

None of the known methods and devices makes it possible to ensure full-fledged scanning by antenna arrays at any angle, including 360 degrees, or to ensure security for a person undergoing inspection, or the safety of maintenance personnel working near the device.

The technical result of the utility model is the integrated security for the screening, maintenance personnel, and other people in the room when turning the antenna arrays to any angle, providing a comprehensive analysis of the presence of dangerous objects under human clothing. An additional technical result is the possibility of operating a lock inspection cabin without the constant presence of maintenance personnel, offline, by automating the process of analyzing the data of the scanning system with automatic classification of dangerous or unauthorized items and banning passage (blocking in the cabin) until unauthorized circumstances are clarified attempts to carry such objects with automatic call of security personnel.

To achieve this result, a gateway security cabin has been proposed in access control and management systems (ACS), characterized by the presence of internal and external casings, the presence of four controlled blocking devices that form an input pair of devices and an output pair, and in each pair of controlled blocking devices there is one blocking device controlled, connected to the inner casing and one device connected to the outer casing, by the presence of a scanning system installed with possibly Tew rotational movements at any angle around the inner housing in the space between the outer and inner casing and intended to receive the hidden under clothing prohibited or dangerous objects.

Besides,

- the scanning system consists of N scanning subsystems located symmetrically with respect to the axis of rotation passing through the center of the cabin, and the rotation angle of each scanning subsystem is N times less than the total angle of all scanning subsystems.

- devices that block the controlled, connected to the inner casing have a "swing type" design, and devices that block the controlled, connected to the outer casing have a "swing" design, sliding, or any other type.

- devices that block the managed, equipped with personal identification devices.

- airlock inspection cabin is equipped with radiation sensors.

- airlock inspection cabin contains built-in scales for weighing the inspected during scanning.

The design of the airlock inspection cabin has inner and outer casings, for example in the form of two cylinders of different diameters having a common axis of symmetry. Between the casings is a scanning system of an electromagnetic or other type, which serves to obtain information about dangerous objects, rotates to any angle (the usual optimal value is 360 degrees), four devices of the controlled devices, of which two devices of the controlled devices are located on the entrance to the airlock inspection cabin, and two controlled blocks are located on the exit side of the airlock inspection cabin. Controlled blocking devices connected to the inner casing ensure the security of the inspected, and controlled blocking devices connected to the outer casing ensure the safety of the personnel when scanning systems move between the casing. Controlled blocking devices connected to the inner casing are of the "swing type", and connected to the outer casing of both the "swing" type and any other type, for example, the "sliding" type.

The rotation angle of each scanning system, if there are more than one, can be N times smaller, where N is the number of individual scanning systems.

The input pair of devices blocking the controlled ones opens only for the passage of the airlock inspection cabin being searched inside. The output pair of blocking controlled devices is opened only for the exit of the security cabin being inspected from the airlock. The input and output pair of blocking controlled devices can functionally be interchanged in order to reverse the flow of inspected ones, for example, at the beginning and end of a working day at a guarded enterprise. In working condition, all four devices of the controlled devices are never open at the same time, which excludes the possibility of unauthorized passage of prohibited items through the airlock inspection cabin. The movement of the scanning systems occurs around the axis of symmetry of the inner casing and only at a time when all the blocking controlled devices are closed.

The choice of the swing type of blocking controlled devices connected to the inner casing is determined by the need to protect the scanning systems being inspected from the residual movement and to mechanically protect complex scanning systems from malicious actions being searched. The opening of the blocking devices controlled towards the entrance or exit can occur both in stand-alone mode of operation, and by command from the operator’s console. When working in stand-alone mode, the cabin is additionally equipped with personal identification devices that impede the procedure for people who do not have special access to pass through the cabin. The cabin can be additionally equipped with radiation sensors that generate an alarm when the specified levels of radiation are exceeded. The cabin can be equipped with scales built in the floor to weigh the inspected during the scan in order to compare its current weight and the pre-known weight corresponding to its identification code

The specified set of essential features will achieve a technical result due to:

- sequential operation of pairs of devices controlled blocking, providing a gateway mode of operation of the cabin.

- there is no danger of getting injured during the movement of scanning systems that make a full revolution, both for the inspected person and for those who are outside the camera by preventing access to moving parts thanks to four closed guarded blocking devices.

- there is no danger of getting injured during the rotation of the body being searched, due to the absence of such rotation.

- Obtaining full and comprehensive information about dangerous or prohibited items hidden under search under clothing, by turning the scanning systems through an angle that excludes the presence of blind spots.

- automation of the cab control process without the presence of an operator on the basis of a computer analysis of the scan results produced in any known manner (for example, described in the utility model patent No. 95130 IPC G01N 22/00 of March 30, 2010), which allows hazardous or forbidden items under clothing on the human body and issue commands to pass through the cabin, in the absence of danger, or generate an alarm to call security officers.

The figure schematically shows a security gateway cabin, where

1 - personal identification device

2 - device blocking managed

3 - searched

4 - outer casing

5 - an internal casing

6 - scanning system 6.

The proposed device, one of the embodiments of which is depicted in the Figure, works as follows.

Open the input pair of blocking devices controlled (in the figure they are shown open). The person being examined passes to the center of the cabin and occupies the previously indicated position. Opening the input pair of blocking controlled devices can occur by the operator’s command or by the correct code entry by personal identification devices 1. When using personal identification devices, the latter can have a working principle based on electronic passes of contact or non-contact action, biometric information on fingerprints, keypad and any other principles used in access control systems. If necessary, personal identification devices can be more than one, including those installed both outside and inside the cabin.

Close the input pair of blocking controlled devices 2. Scan the space inside the cabin with the antenna arrays of the radio wave scanning system 6, making a circular motion a full revolution (total) in the space bounded by the outer casing 4 and the inner casing 5.

Decide on the passage of the inspected 3 through the output devices blocking controlled 2, either by the operator (not shown in the Figure), or using the automatic classification of the information received.

They open the output devices blocking controlled 2 with a positive decision on the absence of dangerous or prohibited items and release the inspected person from the cabin. Otherwise, the input devices are opened blocking controlled 2, prohibiting passage to a controlled area. If necessary, they carry out blocking of the inspected 3 in the cabin and call the security officers, if such an action is provided for by the inspection regulations in the cabin. Blocking devices blocking controlled 2, which were previously open.
