Description

Door swing system for unmanned access control

Technical Field

The present invention relates to a door swing system, and more particularly, to a door swing system for unmanned entrance and exit control, which is intended to be applied to an unmanned entrance and exit inspection station in an airport or the like.

Background

Generally, a gate Swing (Swing Door) associated with an access control system is installed in a station automation system gate (AGM) or the like, and is roughly classified into an Entry Type (Entry Type) and an Exit Type (Exit Type) according to a control method. The former allows the passage of an opening in case of emergency (fire or power outage), while the latter is in any case not subject to opening without the approval of unauthorized personnel. In any event, the rapid operation and accuracy of the door swing system is an important factor in improving the reliability of unmanned access control.

As a prior art document to which the door closer swing can be referred to, korean utility model publication No. 0468123 (prior document 1), korean patent publication No. 1348180 (prior document 2), and the like can be referred to.

According to the prior art document 1, the reciprocating rotation angle of the drive lever connected to the link lever for opening or closing the gate opened and closed by the slide and swing type is classified into the opening and closing operation mode and the opening and closing state lock mode and recognized, and it is possible to control the entry and exit of unnecessary persons. Therefore, smooth rotation operation and durability are expected.

According to the prior art document 2, when a detection signal is inputted from a gate reader, a driving signal is applied by a driving motor to drive a gate of a gate machine in a vertical swing manner, so that the gate of the gate machine is opened, and when the detection signal is not inputted, a default process is performed to fix the gate of the gate machine at the center of the gate machine and close the gate. Therefore, an effect of opening and closing the shutter quickly and more efficiently is expected.

However, the above-mentioned prior art documents have limitations in their application to airport unattended entry and exit checkpoints, and thus many improvements are required.

Detailed Description

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

The invention provides a door swing system for realizing unmanned access control of a gate. The present invention is intended to be applied to a gate pendulum of an unattended entry and exit inspection station in an airport or the like, but is not necessarily limited thereto. The entry and exit audit station 10 is configured to have a plurality of gates 12, and to divide a domestic area and a foreign area. It should be configured so that personnel from abroad cannot enter the domestic area through the door swing provided in the gate 12 in any event, including a power outage.

According to the present invention, the inlet shutter 20 is structured such that a pair of shutters 21 are supported on the inlet side of the shutter 12 so as to be openable and closable, and the shutters 21 are rotated within the forward and reverse opening and closing ranges.

Referring to fig. 1 and 2, a shutter 21, a support shaft 22, a speed reduction portion 24, a drive motor 25, and the like constituting the inlet shutter 20 are shown. An entry gate 20 is provided adjacent to the home area in the gate 12. The shutter 21 is formed of tempered glass of a transparent material so that it is not damaged by human beings. The support shaft 22 is rotatably provided on the side surface of the gate 12 facing each other. The drive motor 25 is connected to the lower end of the support shaft 22 via the speed reduction portion 24. The driving motor 25 employs a BLDC motor capable of accurate and smooth operation. The drive motor 25 positively opens the flap 21, intended to allow one to pass, but may also reversibly open the flap 21, so that a person having a problem in the egress processor 15 is returned after passing.

On the other hand, the outbound processor 15 includes sensors for detecting the movement of a person, in addition to the passport reader, the biometric information camera, and the security checker.

According to a detailed configuration of the present invention, the inlet shutter 20 supports the shutter 21 to be opened and closed within a range of 180 degrees, and is provided with a stopper 26 configured to allow the shutter 21 to be manually rotated when the power supply is turned off.

As shown in fig. 1 and 2, the flapper 21 is provided to be rotatable within a range of about 180 degrees together with the support shaft 22 so as to be opened in the forward and reverse directions. This can be achieved by restricting the stroke range of at least one of the support shaft 22, the speed reducing portion 24, and the drive motor 25. The baffles 21 of the gate 12 keep the gap at the bottom as low as possible to prevent a person from climbing over. The speed reduction portion 24 provided in such a narrow space transmits the rotational force of the drive motor 25 to the support shaft 22 through a right angle based on the worm wheel. The Brake 26 is formed by concentrically connecting an Electromagnetic Brake (Electromagnetic Brake) to the drive motor 25.

Further, according to the present invention, the outlet shutter 30 is structured such that a pair of shutters 31 are supported on the outlet side of the shutter 12 so as to be openable and closable, and the shutters 31 are rotated within a normal opening and closing range.

Referring to fig. 1 and 2, a flapper 31, a support shaft 32, a speed reducer 34, a drive motor 35, and the like constituting an outlet shutter 30 are shown. An exit gate 30 is provided adjacent to the foreign area on gate 12. The main structure of the outlet shutter 30 remains the same as the shutter 21, the support shaft 22, the speed reducing portion 24, and the drive motor 25 of the inlet shutter 20 described above. The driving motor 35 positively opens the shutter 31, intended to allow one to pass, but in any case not causing the shutter 31 to open in the reverse direction.

According to a detailed configuration of the present invention, the outlet shutter 30 supports the shutter 31 to be opened and closed within a range of 90 degrees, and is provided with a stopper 36 configured to restrain the shutter 31 from being manually rotated when the power supply is turned off.

As shown in fig. 2, the flapper 31 is provided to be rotatable within a range of about 90 degrees together with the support shaft 32 so as to be openable only in the forward direction. This can be achieved by restricting the stroke range of at least one of the support shaft 32, the speed reducing portion 34, and the drive motor 35. The speed reducing portion 34 transmits the rotational force of the driving motor 35 to the support shaft 32 through a right angle based on the worm wheel, as in the inlet shutter 20. The brake 36 is formed by being concentrically connected to the drive motor 35.

According to a detailed configuration of the present invention, the brake 36 is a brake having an electric latch 37 or a non-excited operation type brake, and further includes a manual latch 38 that can be provided to the speed reducer 34.

Although not shown in the drawings, the electric latch 37 is used as an example of the brake 36, or a non-excited operation type is used as another example. The former brake 36 always generates a braking force by an electric striker 37 pinned to the solenoid in a normal state. When power is applied by a controller 41 described later, the electric striker 37 is released and the brake 36 is allowed to operate. The latter uses a POWER-OFF brake of a non-excited type, which generates a braking force by the force of a spring attached thereto when POWER is OFF. The manual lock 38 is provided to the decelerating portion 34 by a pin and a handle. When the manager presses the handle, the pin is provided between the gears of the reduction part 34 to restrict rotation. In any case, the stopper 36 keeps the shutter 31 of the outlet shutter 30 closed at the time of power failure.

Further, according to the present invention, the control unit 40 is configured to control the inlet shutter 20 and the outlet shutter 30 by a set algorithm.

Referring to fig. 3, a controller 41, a host 42, a potentiometer 44, a mode input 46, and the like, which constitute the control unit 40, are shown. The controller 41 is constituted by a microcomputer circuit and is mounted on the gate 12. The host 42 is mounted on the gate 12 or disposed at a spaced apart location. The potentiometer 44 is provided in the

speed reduction portions

24, 34, and detects the rotation state of the

support shafts

22, 32. The mode input device 46 is mounted on the controller 41, and performs operation mode selection and setting value adjustment.

The detailed structure according to the present invention is characterized in that the above-mentioned control unit 40 detects the signals of the outbound handler 15, the potentiometer 44, and the mode inputter 46 through the controller 41 under the set condition, and operates the actuator 36 under the set condition to restrict the exit gate 30 from being opened. Fig. 2 and 3 show the connection states of the potentiometer 44, the mode input device 46, and the like to the controller 41. Basically, the inlet gate 20 and the outlet gate 30 receive control signals from the controller 41 based on the main algorithm of the host 42. The control signals perform Open (Open) and Close (Close) operations through the RS232 interface. The entrance gate 20 and the exit gate 30 are normally operated according to the normal signal of the exit processor 15. If an emergency such as a power failure, a fire, or a line interruption occurs, the shutter 31 of the exit gate 30 is closed by the stopper 36 even without the provision of the controller 41.

It will be apparent to those skilled in the art that the present invention is not limited to the embodiments described, but various modifications and variations can be made without departing from the spirit and scope of the invention. Therefore, such modified examples or modified examples should fall within the scope of the claimed invention.
