Description

The alleged invention relates to the construction, namely, the designs of gateway turnstiles used for the controlled admission of people at checkpoints for various purposes. In particular, full-height rotor three-blade gate turnstiles are considered.

A typical full height rotary turnstile and the passage of a person through it is shown in FIG. 1-fig. 3. The turnstile contains fences O1 and O2, a rotating rotor P with three blocking blades 1, 2 and 3, a blocking comb 4 and a rotor drive 5. The blades are formed by the blocking rods arranged in a vertical plane 6. In FIG. Figure 3 shows the man and the position of the turnstile blades after passing through the turnstile. The Roman numeral I denotes the readers of identifiers. A feature of gateway turnstiles is that a person’s right to pass through the control zone is checked when the person’s locked position in a confined space. As a rule, a double control is carried out in gateway turnstiles: the first (external) control allows a person to enter the gateway, for example, using an electronic contactless card, and the second control, which is already carried out in the gateway using either a keypad, or a biometric reader, or a security guard, exit the gateway. At this stage, they also check for explosives, contamination with radioactive, chemical substances, etc. An explanation of the operation of the double-gate turnstile is shown in FIG. 4-7.

In FIG. 5-7 show a three-blade turnstile gateway when viewed from above; O1 and O2 - turnstile fencing; a line with an arrow shows the path of a person passing through a turnstile gateway; the numbers 1, 2 and 3 indicate the rotating blades of the turnstile rotor; the grayed-out area indicates the gateway; the number 4 indicates the blocking comb, which prevents unauthorized passage through the turnstile; Roman numerals I and II indicate the readers of identifiers, respectively, of the first and second control;

in FIG. 5 shows the position of the person during the first control before entering the gateway;

in FIG. 6 shows the position of the person in the second control in the gateway;

in FIG. 7 shows the position of a person after exiting the gateway; while the rotor of the turnstile gateway after the passage of a person made a turn (2 × 120 ° = 240 °).

The purpose of double control in a turnstile gateway is to increase security against unauthorized persons. At the same time, when using double-turnstile gateways with double control, two problems arise:

- firstly, there is a decrease in the throughput of the checkpoint compared to a conventional turnstile, since the time a person passes through the turnstile is doubled; the result of this is that to ensure the passage of a given number of people during a given time, twice as many turnstiles and the width of the passage are required.

- secondly, when passing through the turnstile gateway, it is possible for a person who has not received permission to pass from the access control and access control system (ACS) to enter through the gateway, as illustrated in FIG. 8-fig. eleven; these figures show the passage of three people one after another, while the second person can, without presenting an identity identifier to the access control and access control system (ACS), enter the gateway without permission while leaving the gateway of the first person and then exit the gateway during the entrance to the gateway of the third person, FIG. 8 is a top view of a turnstile gateway with three people in line; FIG. 9 is a top view of the gateway turnstile with one person in the gateway and two in line; FIG. 10 is a top view of the gateway turnstile when the first person leaves the gateway and the second person simultaneously enters the gateway without permission; FIG. 11 is a top view of the turnstile gateway when a third person enters the gateway and at the same time the second person exits the gateway without permission.

The well-known “Full-height rotary turnstile PERCo-RTD-16”, consisting of a rotor, a rack with barrier arms, left and right sections of the passage shaper with indication units, support beams, drive beams with a cover, remote control with cable; nodes providing the turnstile and placed inside the drive beam. The passage mode depends on the position of the turnstile rotor in the initial (closed) state. There are two options for the overlapping of the passage zone by the doors in the initial state, which determine the possible passage modes:

- standard - in the initial state, the passage zone is blocked by one leaf. The standard mode of passage through the turnstile is recommended to be used in cases where there are no particularly stringent requirements for control at the checkpoint;

- airlock - in the initial state of the turnstile, two doors overlap the passage zone, forming a gateway - part of the passage through the turnstile, limited by the sections of the passage shaper and two leaves. The presence of a gateway makes it possible to organize enhanced access control to an object. The gateway access mode is especially effective for controlling the passage of people at the checkpoints of sensitive enterprises, special institutions and other facilities with special access control requirements (Full-height rotary turnstile PERCo-RTD-16. Operation manual, page 37, https: // www. perco.ru/products/polnorostovyy-rotonyy-turniket-rtd-16.2s.php)

This turnstile has the drawback described above as the second - it lacks protection against penetration through the entrance of a person who has not received permission to pass from the ACS.

The closest analogue to the present invention is “Blocking device, controlled, electromechanical, two-section, full-profile, normally closed, with partial overlap of passage zones, rotor type, with a gateway function, blocking”, comprising a guard, a rotating rotor with blocking blades and a rotor drive, consisting 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 - by a vertical blocking wall, from above - with two supporting platforms fastened together by means of bolted joints, and a movable part in the form of two rotors consisting of vertical metal pipes with three blocking flaps of horizontally arranged metal strips, angled 120 in plan relative to each other degrees, characterized in that it is equipped with two load-bearing frames with control mechanisms closing the device from above, two weighing platforms located at the base of the passage zones, and e of the three blocking rotor leaves when the rotors are blocked by the control mechanisms after each rotation of 120 degrees are made with the possibility of blocking the passage zones on both sides with the formation of two physical barriers by unauthorized entry by breaking the blocking rotor leaves and with the possibility of formation, together with the walls of the formation of the passage of closed zones - gateways with controlled input-output (patent for invention RU 2247821 C2, Cl. IPC: Е06В 11/08, date of publ. 2005.03.10)

The disadvantage of this device is that it uses expensive weighing platforms to protect a person who has not received permission to pass from an access control system to get through a checkpoint, which is not necessary in all cases of using full-height turnstiles. In addition, this device can only work in gateway mode with low bandwidth.

The technical result of the invention consists in expanding the scope of the turnstile, increasing its versatility and reducing its cost due to the use of blocking gratings in the turnstile with the possibility of their rearrangement to obtain the turnstile or gateway mode, as well as the use of radiation barriers in the gateway area to protect against penetration through the passage of a person who has not received permission to pass from the ACS.

The achievement of this result is ensured due to the fact that the full-height rotor three-blade turnstile gateway contains a guard, a rotor mounted rotatably in the bearing units, blocking rods connected to the rotor, the turnstile mechanism, light and sound indication, remote control, monitoring and control system access (ACS).

In accordance with the invention, in the gateway zone for protection against unauthorized passage through the turnstile in the gateway mode, radiation barriers are installed that determine the fact of a person being located, producing in this case an additional output signal “human presence in the gateway”, which is further used to control the input-output through the turnstile -Gateway; at the same time, the barrier of the turnstile-gateway is made of a constant part and a rearranged part: a blocking lattice, which, when moving, provides both a turnstile mode and a gateway mode.

In addition, radiation barriers crossing the area of the gateway are installed at such a distance from each other that allows you to determine the fact that a person is in the gateway.

Due to this, the turnstile gateway can operate both in the gateway mode with double verification of a person passing through the device and with reduced bandwidth, and in the mode of a conventional turnstile with a single check and increased bandwidth.

FIG. 16 - the algorithm of the turnstile gateway in gateway mode.

In FIG. 1 and FIG. 2 shows a view of a three-blade turnstile gateway in the turnstile mode - front view (Fig. 1) and top view (Fig. 2). The turnstile contains stationary fences O1 and O2, a rotating rotor P with three blocking blades 1, 2 and 3, a blocking comb 4 and a turnstile mechanism 5. The blocking comb 4 is connected by a screw connection to the fence O1. The blades are formed by blocking rods arranged in a vertical plane 6. The rotation of the rotor and blades is blocked by the turnstile mechanism until permission is obtained. To obtain permission, a person must present a valid identifier. The Roman numeral I denotes the identifier readers on the input and output sides. After obtaining permission, a person can rotate the rotor and blades by an angle of 120 °, after which the rotor and blades are again blocked. The electronic control unit, light and sound indications, and the remote control are not shown.

In FIG. Figure 3 shows that the position of the turnstile gateway blades in the turnstile mode after the passage of a person has changed by 120 °: in place of the blade 1, the blade 2 has become.

In FIG. 4 and 5 show a typical three-blade turnstile gateway in gateway mode when viewed from the front and top; O1 and O2 - gateway turnstile fencing; the arrow shows the direction of a person’s passage through the turnstile gateway; the numbers 1, 2 and 3 indicate the rotating blades of the turnstile rotor; shaded gray indicates the area of the gateway, where a person is "closed" for verification; the barrier grid 4, which prevents unauthorized passage through the turnstile gateway, is connected via a screw connection to the fence O2; Roman numerals I and II indicate the readers of identifiers, respectively, of the first (external) and second (inside the gateway) controls. In FIG. 5 shows the position of the person during the first control before entering the gateway zone. In FIG. 6 shows the position of a person during the second control in the area of the gateway.

In FIG. 7 shows the position of a person after exiting the gateway; at the same time, the rotor of the turnstile-gateway, after a person has completely passed through the gateway, made a turn (2 × 120 ° = 240 °), in place of blade 1, blade 2 becomes.

In FIG. 8-fig. 11 shows an unauthorized passage of a second person through a gateway in the absence of special devices in the turnstile gateway to prevent this; unauthorized access can occur as follows: when the first person leaves the gateway, the second one can enter the gateway without passing the first check, and then, when the third person enters the gateway, the second one can exit the gateway without passing the second check.

In FIG. 12 shows a top view of the gateway turnstile with radiation barriers “L” in the area of the gateway (this can be either a visible light beam or an invisible infrared beam). Beam barriers can be organized with the help of “I” emitters and “P” receivers. If a person crosses the beam, then the receiver “P” detects and changes its output signal (for example, from “0” to “1” or vice versa), and the changed signal is used to control the turnstile (see the flowchart of the algorithm).

Beam barriers are located at a distance of 140-150 mm from each other so that, if there is a person in the gateway, the person blocks at least one beam, while the beam barrier gives the signal "Human presence in the gateway" for ACS. The same figure shows a line of three people.

In FIG. 13 shows that the first person is in the gateway, while it blocks one or more light beams and the second person is prohibited from first checking and entering the gateway until the first person leaves the gateway (Fig. 14); in order to enter the gateway, the second person must pass the first test (Fig. 15).

In FIG. Figure 16 shows the recommended turnstile-gateway operation algorithm for ACS.

The operation of the turnstile gateway according to the algorithm is as follows. First, the presence of a signal from the radiation barriers “Human presence in the gateway” is checked. If there is no person in the gateway, then the first (external) check is allowed and the person enters the gateway. If there is a person in the gateway, then a request is made to the ACS system “Has the first (external) check been passed”. If a person ends up in the gateway without undergoing the first (external) check, this is a violation of the rules of access, and the person can either be blocked in the gateway to find out the reasons or the security is triggered (this is determined by the rules of a particular enterprise). If a person is in the gateway after passing the first (external) check, then he is allowed to pass the second check. When there is a person in the gateway, the first check is prohibited until he leaves the gateway.
