one

The invention relates to the automation of access control systems and can be used at any enterprise or institution.

Known turnstiles are widely known.

applied at pass-through enterprises. Behind; .. The first mechanism of the turntable contains a disk with pdes and a ratchet wheel with a dog, located on the axis of the turntable. The lever of the locking mechanism, hitting the disc groove, keeps the turntable from turning. Ratchet Kojieco with a dog prevents the turntables from turning in a forbidden direction. When pj iHoft is working, the locking lever is o-Bodlt watchman. When automatic, he rel digg: t rovy. an electromagnet controlled by the control of the 1 B tokens with the original cociOHKi-m spinner is fixed. In the short-circuit turnstiles, the counterclocker token is at the moment when the person is holding up a turntable, with L.Jie, which determines the intruder’s difficulty and the possibility of using the postoFH code; , f: .i .iKViov. 1According to the counter of the medal; -a); y ::. Og. about:) a new mechanism. The person, turning the turntable at an angle of 9 °, turns the turnstile, after which the closures of the control of the tokens are reset to the initial state, and the turntable is fixed again.

The closest to the invention is an automatic turnstile containing a turntable, and at the ends of its crosses there are fixed arcuate stoppers, a semi-cylindrical enclosure, a cabinet with an automatic control circuit. The locking mechanism consists of a washer-lock with sockets on the periphery, two levers with traction electromagnets located at an angle of 45 to one another and a ratchet wheel with a dog. In the initial state, the pinwheel is fixed by one of the levers. There are two sub-platforms in the floor: foreign platforms with their position sensors. One platform serves to monitor the person who is inside the turnstile when dialing a code, another - to detect an intruder trying to pass the turnstile 3 outside of the turntable, from the side of the fence. On the front wall of the drawer there is a light panel and a slot for lowering the token. On the side wall of the pedestal from the side of the turntable, a panel with buttons for dialing a code is reinforced. In the cabinet mounted sensor presence counter. The turnstile works as follows. Being outside the turntable, the person lowers the token into the slot. The first check of the token takes place, after which the traction electromagnet is activated, the released turntable is rotated through an angle of 45, after which it is fixed by the second locking lever. The person finds himself on a spring-loaded platform inside the space bounded by the vertex carcasses and a pedestal. Here he dials the code on the keypad. Such work excludes a review of the process of dialing a code by an outsider to ensures the arrest of the violator. When the dialed code of the token is matched, the second traction electromagnet is triggered and the spinner is unlocked. Pro-20 having returned the turntable to 45, the person leaves the turnstile, and the turntable is again fixed by the first locking lever. This automatic turnstile eliminates the possibility of unauthorized monitoring of a code set and ensures the detention of violators. However, it is characterized by a narrow passage between the restraints and the cabinet, which creates inconveniences in its use; the presence of additional parts and assemblies (limiters, the second locking mechanism with a traction electromagnet); low throughput due to double fixation of the turntable; passage in only one direction and a small coefficient of use of the usable area (less than 5% of the total area occupied by the turnstile is used for the passage), as well as low reliability due to the frequent operation of the locking mechanisms (both locking mechanisms are triggered with each pass), the purpose of the invention is Increased reliability and throughput. In the described turnstile this is achieved by the fact that it is equipped with a turntable position sensor and AND, OR and Delay elements, with the outputs of the pad condition sensors through the Delay elements connected to the first inputs of the corresponding AND elements, the second inputs of which are connected to the output of the position sensor turntables, and the outputs - with the inputs of control units of the tokens and with the inputs of other elements AND, to the second inputs of which the inverse outputs of the control units of the tokens are connected, and the outputs through the OR element to the control unit of the locking mechanism niche and through the element of the support - to the alarm unit. 26 In FIG. 1 shows the described turnstile, two projections; in fig. 2 - its functional scheme. The automatic turnstile contains turnstand 1, two fences 2 and 3, which overlap two opposite sections of the turntable, two weight-pruned platforms 4 and 5 with sensors 6 and 7 of the conditions of the platforms (weight sensors). In the enclosures x2 and 3, on the inner side, the input devices 8 and 9 of the control units of tokens are installed. The locking mechanism of the turnstile turnstile contains a ratchet wheel located on the axis of the turntable with a pawl 11, a disk 12, with slots for setting the lock lever 13, a lock lever drive (for example, an electromagnet) 14. The sensor position of the turntable contains a movable part 15 fixed on the axis of the turntable and non-booster part 16. Sensors 6 and 7 are connected via time delays 17 and 18 to the inputs of elements AND 19 and 2O, the second inputs of which are connected to the position sensor of the turntable 16. The outputs of elements AND 19 and 2O are connected to the inputs of blocks 21 and 22 of the control of tokens and with the inputs of the elements 23 and 24, to the second inputs of the latter are connected the inverse outputs of the blocks 21 and 22. The outputs of the circuits 23 and 24 are combined by the element OR 25, the output of which is connected to the block 26 controlling the drive of the locking lever and through the time delay 27 to the alarm signaling unit . In the initial state, the locking lever 13 is held by a spring, and the spinner is unlocked. Sensors 6 and 7 are output. The position indicator of the turntables 16 is turned off or on, depending on whether the turntable was left in the l: ack of the institute by the previous person. At the outputs of the elements And 19 and 20 there is no signal. At the same time, the inputs of the control blocks of the tokens are blocked, and checking of the tokens is impossible. The operation of the automatic turnstile with a passage in one direction, shown in FIG. 1 arrow, is as follows. Entering sector 1, the person turns the turntable through an angle of 9 °, while it loads the weight area 4. A signal appears at the output of sensor 6. After the input device of the control unit of the tokens is opened, a token is inserted into it. Upon further rotation of the turntable, the sensor 16 of its position is triggered. At the output of the element And 19 pos. the drive that unlocks the block g, .sh counters. The control of the token occurs, 3 this time the person is between the wings of the

ki and fencing. When the counter corresponds to the output of the block 21 of the counter / x tokens, a signal appears at the inverse input O, this signal enters the input of the element 23, and the second input with a delay comes signal 1 from the output of the element Wi 23 signal O not; :: is, and the locking mechanism drive does not work. The man, removing the token, rotates the turntable.; At an angle of 9O and leaves the automaton / rnike. If the sensor 6 and the rotor position sensor have triggered, and the token is not inserted, the tone of the outputs of elements 19 and 23 appears in signal 1, which turns on the actuator of the lock mechanism, Rjlag falls into the slot of disk 12 and fixes the fan. You can unlock it only by inserting the corresponding token into the contour socket of device 8. If the time the presence of signal 1 at the output of the element And 23 is longer than the time delay specified by the circuit 27, then the alarm block is triggered. When passing in the other direction, the turntable is turned and passes from sector III to sector IV, where there is an entrance nest of the control unit of tokens on the fence, and a spring-loaded platform 5 is mounted in the floor. The automatic turnstile works in this case. With the simultaneous passage of the automatic turnstile to the entrance and exit, it works as follows. Turning the turntable through an angle of 9 °, two people pass from sectors I and 331, respectively, into sectors P m IV, and both sensors 6 and 7 are triggered, and then the sensor is positioned. 16. If S ft of the token are inserted into the control sockets of the devices 8 and 9 blocks of control tokens, the locking mechanism does not work. Having turned the turntable at an angle of 9 °, both people leave the automatic turnstile. If by the time the position sensor turns on, any one of the tokens is not inserted into: i: i :: rpOJt.Hoe socket, then the constipation (MsxcKHSiv) will work, and the spinner will lock. In ocTanbHCi / i, the device operates in the same way as the first c: n.y -lajo, With tar, for its operation, the control of the tokens is carried out in an enclosed space, which ensures the secrecy of the control of the tokens (code set) and allows the intruder to be retained. In this case, the number of actuations of the locking mechanism is significantly reduced:;. Delays 17 and 18 are included between sensors 6 and 7 and IP 2O elements.

No signal 1 at the sensor outputs. When sensors 6 and 7 are loaded, signal 1 appears at their outputs. When the load is removed, signal 1 at the output of the sensors changes to signal O, but at the output of the time delay the signal changes after a certain period of time. This helps to increase the reliability of the automatic turnstile during short-term disappearances of signals on the sensors. The inclusion of the delay element 27 in the alarm block scheme excludes its false triggering in the case of hitches when checking tokens. Thus, the described turnstile works more reliably, since it reduces the number of actuations of the locking mechanism and eliminates the false alarms of the actuator and the alarm signaling unit. It provides control over the passage in two directions, which increases the utilization rate of the usable area and, consequently, increases the throughput capacity. In addition, it eliminates the limiters and the second locking mechanism.
