Description

The present invention relates to technical means of physical protection, namely the turnstiles of automated checkpoints of nuclear hazardous facilities and other critical facilities, and can be used for automated control of personnel access to the building, zone and the facility when working as part of a control system and access control, or offline, and providing a physical barrier to unauthorized entry.

A technical means of physical protection is known - the turnstile of an automated checkpoint of an object, designed to control the access of personnel to the building, zone and territory to provide physical obstruction to unauthorized entry and related to blocking, controllable, electromechanical, two-section, full-profile, normally closed, partially closed devices overlapping passage areas, rotor type: full-height two-section rotor turnstile MD 120 FI GUNNEBO MAYOR (UK) [1].

Its disadvantages include:

1. The presence in the passage zones of only one physical barrier that prevents unauthorized entry by breaking the blocking rotor leaf.

2. The absence of devices that exclude the possibility of two people passing through one pass.

3. The absence of gateways in the passage zones with controlled inputs - outputs that ensure the blocking of a person in case of violation of the access control mode.

The specified turnstile has in the passage zones only one blocking rotor leaf located in the middle of the passage zone and prevents unauthorized entry, operates on the principle of a gate, does not exclude the possibility of two people passing through one passage and is not able to block a person in the passage zones if they violate the passage regime.

To organize a gateway with a controlled entrance - exit, on the basis of this turnstile, it is necessary to install two such turnstiles, one after the other. At the same time, the blocking rotor leaves of the two turnstiles, blocked in the initial position, and the closed space between the turnstiles form a gateway. The blocking shutters of the rotors of two turnstiles play the role of entrance and exit doors. Entrance to the gateway is carried out after unlocking the rotor of one of the turnstiles and turning it manually in the direction of the passage. The gateway is exited after the rotor of the second turnstile is unlocked and turned manually in the direction of the passage.

The objectives of the invention are:

1. Increased resistance to overcoming when trying to unauthorized entry through the zone of passage of the turnstile by breaking the blocking rotor flaps.

2. Exclusion of the possibility of two people passing through one pass.

3. Creation of gateways in the passage areas of the turnstile with controlled inputs - outputs.

To achieve these goals, the rotors of the proposed device in the initial position, in contrast to the aforementioned analogue, are rotated 180 degrees, with two of the three blocking rotor flaps, when the rotors are blocked by control mechanisms after each rotation by an angle of 120 degrees, are made with the possibility of overlapping passage zones on both sides with the formation of two physical barriers to unauthorized entry by breaking open blocking wings of rotors and with the possibility of formation together with the walls of formation passage of closed zones - gateways with controlled input - output. Weight platforms located at the base of the passage zones provide a measure of the weight of the subject to exclude passage for two on one pass. Entrance to the gateway is carried out after unlocking the rotor and turning it manually in the direction of passage. The exit from the airlock is carried out only after re-unlocking the rotor and turning it manually in the direction of passage.

Figure 4 schematically shows a top view, without covers, of a blocking device, controlled, electromechanical, two-section, full-profile, normally closed, with partial overlap of passage zones, of a rotor type, with a lock function, blocking.

Structurally, the blocking device, controlled, electromechanical, two-section, full-profile, normally closed, with partial overlap of passage zones, of rotor type, with a lock function, locking, consists of a fixed part in the form of a metal frame formed on both sides by vertical walls of the passage formation, in the center - a vertical blocking wall 7, from above - two load-bearing frames 10, from below - two weighing platforms 4, fastened together by means of bolted joints, and the movable part in e two rotors consisting of vertical metal pipes 6 with three barrier flaps from horizontally arranged metal strips 5 deployed in a plane relative to each other by an angle of 120 degrees.

The vertical walls of the passage formation are formed by the main walls 2 and the side walls 1 and 3, fastened together by means of bolted joints. Contactless readers of electronic identification signs 11 are installed on the side walls 1 and 3. Inside the device’s passage zones, code-type devices 8 are fixed on the central beams of the main walls 2. Control mechanisms 9 and controllers for access control devices 12 are installed on the supporting frames 10.

The rotors have lower and upper nodes of rotation. The lower nodes of rotation are ball bearings mounted on weighing platforms 4. The upper nodes of rotation of the rotors are formed by locking discs of the control mechanisms 9, mounted on shafts (square section) of the upper part of the rotors, rotating in double-row spherical bearings of the bases of the control mechanisms 9.

The weighing platforms 4 are made in the form of separate blocks in closed, metal cases and in a plan shape corresponding to the profiles of the vertical walls of the passage formation.

In the initial position, the rotors of the device are blocked by the control mechanisms 9. Two of the three barrier rotor leaves, when the rotors are blocked by the control mechanisms after each rotation by an angle of 120 degrees, are made with the possibility of overlapping passage areas on both sides with the formation of two physical barriers to unauthorized entry by breaking the blocking wings rotors and with the possibility of formation, together with the vertical walls of the formation of the passage, closed zones - gateways with a controlled input - output.

The state of the passage zones in the initial position is normally closed. This state is provided by the control mechanisms 9 and does not depend on the availability of power supply.

Each passage zone is controlled by a separate access control device controller 12, which provides two-way personnel passage when the pass code and personal identification signs - the subject’s personal code and weight coincide with the data stored in the memory of the access control device.

The pass code - a plastic card is entered using a contactless reader 11, a personal code - using a dialing device 8. The weight of the subject is measured using the weighing platform 4 while entering a personal code.

In the initial position, the passage zones of the device are closed on both sides by the blocking wings of the rotors. The rotors are blocked by the control mechanisms 9. When a pass is presented - a plastic card to the reader 11 - the code recorded in the pass is identified in the access control controller 12. When the pass code matches the data stored in the memory of the access control controller, the control mechanism 9 unlocks the device’s rotor in direction of entry, providing free entry into the passage area for identification. After the rotor rotates from its initial position by an angle of 120 degrees, the control mechanism 9 automatically locks the rotor, forming a closed zone in the passage zone - a gateway in which the subject is identified by a personal code entered using a code dialing device 8 and measured by the weight of the subject. If the personal code of the subject and the parameters of its weight coincide with the data stored in the memory of the controller of the access control means 12, the control mechanism 9 unlocks the rotor in the exit direction, providing free exit from the passage zone.

If the pass code or pass time does not match the data stored in the memory of the access control device 12, the device does not open the pass zone, thereby creating a physical barrier to unauthorized entry into the protected area.

When using a badge that is on the wanted list, when trying to re-pass in the same direction on the same pass, when trying to walk together on the same pass, when trying to select a code, or typing a code for a time longer than the set code, the device does not open the passage zone to the exit, and the intruder of the access control mode remains blocked in the passage zone.

The applicant has developed a set of design documentation GKAZH.425712.001, made prototypes of the proposed device and tested them. Tests of prototypes confirmed the full implementation of the destination indicated by the applicant.
