Technical Field

An entrance and exit control device is generally installed at an entrance and exit of a building or a facility such as a subway, and only people having a certain condition are allowed to enter and exit. Such access control devices are also known as access doors or gates. Generally, the access door is operated by a user to open the door (opening/closing unit) using a security card. Recently used access doors employ biometric information such as fingerprints to open the door.

The types of the access door include a Swing door (Turn Type Gate), a Slide door (Slide Type Gate), a Swing door (Swing Type Gate), and the like.

The revolving door is an entrance door provided with a plurality of bars (bar) that are rotated by a shaft. The revolving door has the advantage of low installation cost, but has the inconvenience of requiring an artificial push rod.

Therefore, a sliding door in which a door automatically slides or a swing door in which a door rotates around a rotation shaft is frequently used in recent years.

One of the main benchmarks for evaluating access performance is processing capacity. The processing capacity of the access door is determined based on the driving speed of the door (opening/closing unit) and the size of the door. That is, the faster the door driving speed is, the larger the number of people who can travel together within a predetermined time is, the smaller the door size is, a plurality of doors can be installed within a predetermined area, and the number of people who can travel together is also increased.

In addition, the durability of the access door, particularly the durability of the door (opening/closing portion), greatly affects the maintenance cost of the access door, and therefore, is a main performance evaluation criterion of the access door. The access door processing capacity will be greatly reduced when repaired due to door failure.

Fig. 1 shows an example of a conventional access door. According to the sliding door shown in fig. 1, a door (opening/closing portion) D of a predetermined size is inserted into the door body B. Therefore, the width of the access door main body B should be greater than or equal to the width of the door D, and thus there is a limitation in reducing the width of the access door main body B. Further, the structure of sliding the door D left and right has a limitation in increasing the driving speed of the door, and is disadvantageous in durability.

As described above, the conventional access door cannot sufficiently satisfy the conditions of sufficient processing capacity and durability, and the same applies to a swing door or a swing door not shown in the drawings.

In addition, conventional entry and exit doors have many problems. For example, in the conventional access door, since a door having a predetermined size is coupled to a door body, it is fundamentally impossible to freely adjust the installation width of the access door. That is, in order to form channels (or lanes) of various sizes, access doors (or gates) individually formed according to the width of each channel are required.

Therefore, there is a need in the access industry for new structural access doors that address these multiple technical problems.

Fig. 2 is a block diagram showing the configuration of the access control device 1 according to the embodiment of the present invention, and fig. 3 is a diagram schematically showing the external shape of the access control device 1 according to the embodiment of the present invention.

The entrance/exit control device 1 for a control passage includes a door body 100, an opening/closing unit 200, and a driving unit 300, and may further include an identification unit 400, a guide unit 500, a user number measurement unit 600, a communication unit 700, and an audio unit 800.

The door body 100 is installed in the passageway to form the external appearance of the access control device 1, and may support, protect and accommodate various components, including the installation frame 110, the support frame 120 and the accommodation space 130.

The opening/closing part 200 is coupled to the door main body 100 and includes a Folding Arm (Folding Arm)210 whose outer shape is changeable. The opening/closing unit 200 may open/close the passage by changing the outer shapes of the open mode and the closed mode, and may further include a joint type slider 220 and a pressure sensor 230.

The driving part 300 is combined with the door main body 100, drives the opening and closing part 200 and controls the operation of the opening and closing part 200. Also, the driving part 300 may include a motor 310 and a push module 320.

Fig. 4 is a view showing various modified embodiments of the door main body 100 of one embodiment of the present invention. The door main body 100 is described in detail with reference to fig. 4.

The door main body 100 includes a setting frame 110, a supporting frame 120, and an accommodating space 130.

The installation shelf 110 is installed on the bottom surface of the passageway, and the support shelf 120 is installed on the passageway alone or in combination with the installation shelf 110 installed on the passageway to support the entrance and exit control device 1 as a whole. The receiving space 130 is located on one surface of the door main body 100, and provides a space in which the opening and closing part 200 and the driving part 300 can be coupled to the door main body 100.

In the case where the support stand 120 is separately provided in the shaft as in a of fig. 4, the installation of the stand 110 is not a necessary component. However, in the case of b, c and d of fig. 4, the installation shelf 110 may be installed on the aisle, and the support shelf 120 may be connected to the installation shelf 110.

The setting frame 110 and the supporting frame 120 are made of various materials. For example, the installation frame 110 and the support frame 120 may be made of a material having high hardness, such as metal.

In particular, the support frame 120 may have a vertical structure as shown in a of fig. 4, a diagonal structure as shown in b of fig. 4, a polygonal structure as shown in c of fig. 4, an X structure as shown in d of fig. 4, or a circular structure (not shown).

Also, more than one (one or more) receiving spaces 130 may be provided in the door main body 100. For example, the receiving spaces 130 are symmetrically disposed on both sides of the support frame 120 with the support frame 120 as an axis.

Therefore, one support stand 120 may have two accommodation spaces 130, and the opening and closing part 200 and the driving part 300 may be detachably or insertably provided in each of the accommodation spaces 130.

Also, the receiving space 130 is provided inside the support frame 120 to provide a mounting space in which the opening and closing part 200 and the driving part 300 are detachably or insertably provided. The opening/closing unit 200 and the driving unit 300 are positioned on the same axis or rail to perform functions. Therefore, the mechanism of the entrance control device 1 can be simplified by using the configurations of the opening/closing unit 200 and the driving unit 300.

When the accommodation space 130 is provided in the support frame 120 or on one surface thereof, the overall size of the access control device 1 can be reduced. Therefore, with this configuration, the number of access control devices 1 installed in a limited space can be increased, and eventually, the number of users who use an access control system including a plurality of access control devices 1 in the same time period can be increased.

Fig. 5 is a diagram showing a detailed structure of the opening/closing portion 200 according to an embodiment of the present invention, fig. 6 is a diagram showing a closing mode of the opening/closing portion 200, and fig. 7 is a diagram showing an opening mode of the opening/closing portion. The opening and closing part 200 and the operation of the opening and closing part 200 according to an embodiment of the present invention will be described in detail with reference to fig. 5 to 7.

The opening and closing part 200 may have a folding arm 210.

The access control device 1 may have one or more (one or more) opening/closing units 200. For example, the opening/closing units 200 are symmetrically located on both sides of the support frame 120 with the support frame 120 as an axis.

Also, referring again to fig. 2, the opening and closing part 200 may further include a pressure sensor 230.

The pressure sensor 230 may be disposed at one side of the folding arm 210 or coupled to the outside of the folding arm 210, and when the opening and closing part 200 is changed to the closed mode, the pressure sensor 230 may sense a specific object including a user.

When the open/close unit 200 is changed to the closed mode, the pressure sensor 230 may stop the operation of the open/close unit 200 when it senses a specific object. For example, if a pair of access control devices 1 are provided to face each other, and an object is present between a pair of opening/closing units 200, the pressure sensor 230 located outside each opening/closing unit 200 can sense the object, and each access control device 1 can promptly stop the operation of the opening/closing unit 200 or change the opening/closing unit 200 to the open mode.

Therefore, the access control device 1 can improve the safety of the user by the pressure sensor 230.

The folding arm 210 of the opening/closing unit 200 may include a first link 211, a second link 213, and a rotating member 215.

Specifically, the folding arm 210 includes: a first link 211 having one end 211a rotatably coupled to the door main body 100; the second link 213 has one end 213a coupled to the door main body 100 and linearly movable by the driving part 300, and the other end 213b foldably coupled to the other end 211b of the first link 211.

And, the first link 211 is provided on the receiving space 130, and one end 211a is rotatably coupled to the support bracket 120 in the door main body 100.

Also, the folding arm 210 may further include: the circular rotating member 215 is coupled to the other end 211b of the first link 211 and the other end 213b of the second link 213, and naturally folds the first link 211 and the second link 213.

That is, the rotating member 215 functions to connect the first link 211 and the second link 213 to each other, so that the first link 211 and the second link 213 can implement a folding structure.

When the folding arm 210 becomes a folded (Fold) structure in which the first link 211 and the second link 213 are folded, the opening and closing part 200 becomes a closed mode, and when the folding arm 210 becomes an unfolded (Unfold) structure in which the first link 211 and the second link 213 are folded, the opening and closing part 200 becomes an open mode.

When the opening/closing portion 200 is changed to the closed mode by the driving portion 300, as shown in fig. 6, the one end 213a of the second link 213, which is movable in position, moves 602 in the direction of the one end 211a of the first link 211, and the portion of the rotating member 215 corresponding to the center portion of the folding arm 210 protrudes in one direction. For example, a portion of the rotating member 215 corresponding to the center portion of the folding arm 210 protrudes in the wall X direction. Therefore, the access control device 1 closes the passage Y to restrict the access of the user.

When the opening and closing part 200 is changed to the open mode, as shown in fig. 7, the one end 213a of the second link 213, which is movable in position, is moved in the opposite direction to the one end 211a of the first link 211, and when the opening and closing part 200 is changed to the closed mode, the protruding rotating member 215 portion is moved in the opposite direction to the one direction. For example, the rotating member 215 corresponding to the center portion of the folding arm 210 moves in the opposite direction of the wall X (the door main body 100 direction).

In other words, when the opening and closing part 200 becomes the closed mode, a part of the folding arm 210 becomes the protruded folding structure, and when the opening and closing part 200 becomes the open mode, the folding arm 210 becomes the unfolded structure in which the protruded folding arm 210 is restored to the original state.

When the folding arm 210 is changed from the folded configuration to the unfolded configuration, the access control device 1 reopens the closed pathway Y, allowing the user to access the access control device 1.

The opening and closing modes of the opening and closing part 200 and the folding and unfolding structures of the folding arm 210 are words used for distinguishing terms. Therefore, the open mode and the close mode of the opening/closing unit 200 and the folding structure and the unfolding structure of the folding arm 210 are not independent results based on a fixed reference such as a time interval, but are related to each other.

As shown in fig. 6 and 7, the length 601 of the protruding portion of the rotating member 215 when the folding arm 210 is in the folded configuration may be greater than the lengths 602 and 701 of the movement of the end 213a of the second link 213 when the folding arm 210 is in the folded configuration.

Specifically, if the lengths of the first link 211 and the second link 213 are the same, the length of the entire folding arm 210 is a, the length of the movement of the one end 213a of the second link 213 is b, the length of the partial protrusion of the rotating member 215 when the folding arm 210 is in the folded configuration or the unfolded configuration is c, and the angle formed by the second link 213 and the direction of the movement of the one end 213a of the second link 213 is θ, the following equation 1 is satisfied.

Equation 1:

therefore, the temperature of the molten metal is controlled,

when the angle θ having a value between 0 ° and 90 ° is a value between 0 ° and about 53.13 °, the length b over which the one end 213a of the second link 213 moves is shorter than the length c over which the rotating member 215 partially protrudes when the folding arm 210 is changed into the folded or unfolded configuration.

And, when θ is a value between about 53.13 ° and 90 °, the length b of the movement of the one end 213a of the second link 213 is longer than the length c of the partial protrusion of the rotating member 215 when the folding arm 210 is changed into the folded configuration or the unfolded configuration.

As a result, if θ is controlled such that the length c601 of the part of the rotating member 215 protruding when the folding arm 210 is in the folded configuration or the unfolded configuration is longer than the length b (602; 701) of the movement of the one end 213a of the second link 213, the linear movement length (602; 701; b) of the access control device 1 is relatively shorter, and the access control device has a longer opening and closing length (601; c). Therefore, the access control device 1 has an effect of being able to increase the opening and closing speed of the opening and closing portion 200.

Fig. 8 is a diagram illustrating a modification of the opening/closing portion 200 of the joint type slider 220 according to the embodiment of the present invention.

The motor 310 provides power for driving the opening and closing part 200, and referring to fig. 2, the opening and closing part 200 may further include a joint type slider 220.

The joint type slider 220 is rotatably coupled to the first link 211 and may be disposed on the receiving space 130.

Also, the articulated slider 220 may be a shoulder joint structure, and the folding arm 210 naturally changes from a straight structure to a folded structure.

Specifically, when the first link 211, the second link 213, and the rotating member 215 are aligned in a line, and the folding arm 210 is positioned inside the accommodating space 130 in a line configuration, the first link 211 is slid by the joint type slider 220, so that the folding arm 210 can be changed from the line configuration to a folding configuration protruding outside the accommodating space 130.

Since the opening and closing part 200 further includes the joint type slider 220, the folding arm 210 can be naturally changed into the folding structure even though the inside of the receiving space 130 is formed in the straight structure in the process that the folding arm 210 is repeated between the opening mode and the closing mode. In other words, even if the access control device 1 does not provide additional power to the joint type slider 220, the driving part 300 can drive the second link 213 to change the structure of the folding arm 210 to the folding structure.

That is, when the motor 310 moves the one end 213a of the second link 213 to the first link 211 direction in order to control the operation of the opening and closing part 200, the joint type slider 220 of the shoulder joint structure can be folded like a shoulder joint of an actual body, and the first link 211 and the second link 213 and the rotating member 215 can be changed to the folded structure.

Fig. 9 is a diagram illustrating a modification of the opening/closing portion 200 of the push module 320 according to an embodiment of the present invention.

The driving part 300 may further include a push module 320 in addition to the motor 310.

The push module 320 functions to push the folding arm 210 using power provided by the motor 310.

When the first link 211, the second link 213, and the rotating member 215 are aligned in a line, and the folding arm 210 is located inside the accommodating space 130 in a straight structure, the pushing module 320 functions to push the folding arm 210 in a direction outside the accommodating space 130, so that the folding arm 210 becomes a folding structure protruding from the straight structure to the outside of the accommodating space 130. Accordingly, the push module 320 may be disposed inside the receiving space 130 in the door main body 100.

Further, the Motor 310 may be a Ball-Screw Type Motor (Ball-Screw Type Motor) or a Linear Type Motor (Linear Type Motor), but the Motor 310 need not be a Linear Type Motor.

When the motor 310 is a linear motor, the entrance and exit control device 1 does not generate noise when the opening/closing portion 200 is driven, in view of the characteristics of the linear motor. Therefore, the access control device 1 may further include an acoustic portion 800 that functions as a speaker.

When the opening/closing unit 200 is controlled or driven by the driving unit 300, the audio unit 800 can provide a predetermined audio to the user of the access control device 1. For example, the preset sound may be a robot sound, a mechanical sound, a sound of a specific person, a song, etc., and the preset sound is stored in the sound unit 800 in a data format.

Fig. 10 is a diagram showing a detailed structure of the recognition part 400 of one embodiment of the present invention, and the recognition part 400 is described in detail with reference to the foregoing description and fig. 10.

The access control device 1 allows only authorized persons to pass through by using the identification portion 400. The recognition unit 400 may include at least one of a fingerprint recognition module 410 for recognizing a fingerprint of a user of the access control device 1 in order to recognize the user of the access control device 1, a vein recognition module 420 for recognizing a vein form of the user of the access control device 1, an iris recognition module 430 for recognizing an iris of the user of the access control device 1, and a face recognition module 440 for recognizing a face form of the user of the access control device 1.

The identification part 400 may have only one specific identification module 410, 420, 430 or 440 to identify the user of the access control device 1, and when it is necessary to increase the security level, the identification part 400 may identify the user of the access control device 1 using the entire modules 410, 420, 430 and 440.

The identification unit 400 may further include a database-type storage unit (not shown) or a user registration unit (not shown) for storing user information including at least one of fingerprint information, vein information, iris information, and face information of a user of the access control device 1, which are stored in advance.

The recognition unit 400 compares the user information previously stored in the storage unit (not shown) or the user registration unit (not shown) with the fingerprint, vein pattern, iris, and face pattern of the user recognized by the respective modules 410, 420, 430, and 440, and if they match, the drive unit 300 changes the opening/closing unit 200 to the open mode, and if they do not match, the drive unit 300 keeps the opening/closing unit 200 in the closed mode.

In addition, when the comparison result is inconsistent, the recognition unit 400 may provide a preset sound through the sound unit 800. For example, if the comparison results of the recognition units 400 do not match, the access control device 1 may provide a voice such as "unauthorized user" or "please re-recognize" through the audio unit 800.

Also, each of the modules 410, 420, 430, and 440 may sense a fingerprint form, a vein form, an iris form, or a face form, which needs to be obtained by an optical method, using a camera. In which the modules 410, 420, 430, and 440 are adjacently disposed, so that the access control apparatus 1 can improve the efficiency of user identification.

In addition, if the recognition part 400 is in the form of a ball or a column, the modules 410, 420, 430, and 440 may be positioned inside the hollow recognition part 400, and a housing made of a permeable material such as glass may be provided on the outer surface of the recognition part 400.

Further, even if the body of the user does not directly contact the surface of the recognition part 400, the recognition part 400 can perform fingerprint pattern recognition or vein pattern recognition of the user, and the recognition part 400 can perform face pattern or iris pattern recognition while the user approaches the recognition part 400 from the outside.

The user information recognized or obtained by the recognition part 400 may be named user biometric data including at least one of a fingerprint form, a vein form, an iris form, and a face form of the user. Each module 410, 420, 430, 440 may independently identify or obtain user biometric data that the respective module is capable of sensing.

In the case where the identification unit 400 includes all of the modules 410, 420, 430, and 440, the access control device 1 can open the opening/closing unit 200 even if a part of the biometric data identified by the modules 410, 420, 430, and 440 is sensed. For example, even when the fingerprint recognition module 410 completes sensing the fingerprint pattern, the access control device 1 can open the opening/closing portion 200. This makes it possible to increase the recognition speed of the recognition unit 400 and to increase the opening/closing driving speed of the entire entrance/exit control device 1.

Fig. 11 is a diagram showing a detailed structure of the guide part 500 according to the embodiment of the present invention.

The guide section 500 senses a plurality of users entering and exiting the control apparatus 1. In addition, in order to improve user convenience, when a plurality of users are sensed, the guide part 500 may guide a specific user to enter the access control device 1.

Specifically, the guide part 500 includes: a first sensing module 510 that may be disposed at one end of the door main body 100; a second sensing module 520 may be disposed at the other end of the door main body 100; and an entry guidance module 530. The first sensing module 510 and the second sensing module 520 may be located on the access control device 1, but may also be provided at a place separate from the access control device 1.

The access control device 1 is a device installed in a passage to control passage, and is generally installed so that a user can pass in both directions. Therefore, the first sensing module 510 and the second sensing module 520 are located at two ends of each supporting frame 120, and are symmetrical to each other with the supporting frame 120 as a reference.

More than one entry guide module(s) 530 may be provided in the access control device 1. For example, when the access control device 1 has two entry guide modules 530, the entry guide modules 530 are provided at positions adjacent to the first sensing module 510 and the second sensing module 520, respectively, so that users in both directions can be guided.

The first sensing module 510 may sense one user of the access control device 1 and determine a distance to the sensed user. The second sensing module 520 can also sense other users of the access control device 1 and determine the distance to the sensed user.

Thereafter, when one of the first sensing module 510 and the second sensing module 520 senses a user, the guiding part 500 guides the sensed user to enter the access control apparatus 1 by using the entry guiding module 530. When both the first sensing module 510 and the second sensing module 520 sense the user, the guiding part 500 guides the user, which is sensed first, to enter the access control device 1 by using the entry guiding module 530 according to the sensing order, or guides the user, which is closer to the sensing distance, to enter the access control device 1 by using the entry guiding module 530 as a reference.

That is, the guide unit 500 may guide the plurality of sensed users to enter and guide the plurality of sensed users to different directions according to various criteria such as a sensing order and a distance.

The guide unit 500 compares the distance to one user and the distance to another user measured by the first and second sensing modules 510 and 520, and guides the one user and the another user to enter the access control device 1 by the entrance guide module 530. The entry guide module 530 turns on the LED to one user or another, indicating that the entry control device 1 can be accessed preferentially. The method and form of the entry guide module 530 to turn on the LED are not limited.

For example, when a user who wants to enter a plurality of access control devices 1 from two directions simultaneously, the first sensing module 510 and the second sensing module 520, which are symmetrically disposed, sense the user in the directions, respectively, and measure the distance between the users.

Then, the guiding unit 500 may compare the distance measured by the first sensing module 510 with the distance measured by the second sensing module 520, and display a prompt such as an arrow mark or "available" on the LED of the user with a short distance by the entry guiding module 530, and display a prompt such as X, "unavailable" or "please wait" on the LED of the user with a long distance.

Accordingly, the access control device 1 can improve user convenience, and can prevent a collision between a user and the access control device 1 caused by a plurality of users using the access control device 1 at the same time.

Referring again to fig. 2, the access control device 1 may further include, as described above: a user number measuring section 600 for measuring the number of users of the access control device 1, a communication section 700 for transmitting and receiving information related to the access control device 1 to and from a predetermined terminal, and a control section 900 for monitoring information related to the access control device 1.

The user number measurement unit 600 and the communication unit 700 may be located in the access control device 1.

The communication unit 700 may be wirelessly linked with a predetermined terminal to transmit information related to at least one or more of the door body 100 opening and closing unit 200, the driving unit 300, the identification unit 400, the guide unit 500, the user measurement unit 600, the communication unit 700, and the audio unit 800 to the predetermined terminal.

When the communication unit 700 transmits information, a wireless communication technique can be used. For example, the communication unit 700 may use a wireless communication technology such as Bluetooth (Bluetooth), Zigbee (Zigbee), LTE, or wireless network (Wi-Fi), but is not limited thereto.

The preset terminal refers to a digital device capable of communicating. For example, the preset terminal may be a smart phone, a smart tablet, a smart glass, a smart watch, a notebook, a computer, or a PDA, but is not limited thereto.

The user number measuring unit 600 can measure the number of users who enter or exit the access control device 1 by using at least one of the information on the number of times of driving the opening/closing unit 200, the information on the number of times of folding structure deformation and the information on the number of times of unfolding structure deformation of the folding arm 210, the information on the number of times of user identification of the identification unit 400, and the information on the number of times of user entry guidance of the guide unit 500. The user number measuring unit 600 may measure the number of users on a certain basis, such as the number of users in a day and the number of users in a specific time.

The information transmitted from the communication unit 700 to the preset terminal may include error information related to at least one of the door body 100, the opening/closing unit 200, the driving unit 300, the identification unit 400, the guide unit 500, the user number measuring unit 600, the communication unit 700, and the audio unit 800, driving frequency information of the opening/closing unit 200, folding structure deformation frequency information and unfolding structure deformation frequency information of the folding arm 210, user identification frequency information of the identification unit 400, at least one of user entry guide frequency information of the guide unit 500, and user number information of the access control device 1 measured by the user number measuring unit 600.

The control section 900 may display information related to the access control apparatus 1 by a display module (not shown in the drawings). The control unit 900 may monitor information related to the access control apparatus 1 by using separate software, or may change the settings of the respective components constituting the access control apparatus 1.

For example, the control unit 900 may change the mode of the opening/closing unit 200, the recognition method of the recognition unit 400, the guidance method of the guidance unit 500, transmit information to a preset terminal through the communication unit 700, provide audio settings and changes to the audio unit 800, and acquire and display error information of each component constituting the access control device 1.

By transmitting and receiving information through the communication unit 700, the predetermined terminal can analyze, manage, and analyze error information related to the access control device 1. Further, the access control device 1 can be remotely maintained and managed by control software of the access control device 1 provided in a predetermined terminal. Further, the controller 900 can change the installation of the access control device 1 and monitor the access control device 1 without detaching the access control device 1. Therefore, the convenience of the administrator of the access control apparatus 1 can be improved.

Fig. 12 is a diagram showing an access control system including a plurality of access control devices 1 according to one embodiment of the present invention, and the access control system 2 will be described in detail with reference to fig. 2 to 11 and 12.

The access control system 2 may include a plurality of access control devices 1, a plurality of access control devices 1 may be provided at predetermined intervals to form a passage, and a plurality of access control devices 1 may be provided in pairs and in opposition to each other.

The access control system 2 can adjust the predetermined interval by controlling the length of protrusion (the length of protrusion of the rotating member 215) when the folding arm 210 included in each of the plurality of access control devices 1 constituting the access control system 2 is in the folded configuration.

Therefore, as shown in fig. 12, when a plurality of access control devices 1 are provided, the size of the space occupied by the access control system 2 can be freely adjusted.

Comparing d1, d2, and d3 of fig. 12 showing a plurality of widths of the access control system 2, d1 is the widest of the widths d1, d2, and d3 of the access control system 2 in which a plurality of access control devices 1 are provided, d2 is smaller than d1 but larger than d3, and d3 is the smallest of the widths d1, d2, and d 3.

If the access control system 2 is implemented by freely setting the installation width of the access control devices 1, the cost for resetting the access control devices 1 can be saved, and the space utilization rate can be improved.

As described above, the opening/closing unit 200 and the driving unit 300 are provided on both sides of the support frame 120, and the identification unit 400 is provided in both directions of the access control device 1, so that the space utilization rate of the access control system 2 can be improved.

The functions of the access control device 1 and the access control system 2 can be realized by an external power supply or a built-in battery. Further, the respective components of the access control device 1 are connected or interlocked with each other by wire or wirelessly, and the functions of the respective components can be controlled independently.

In the access control device 1 described above, the folding arm 210 is provided in the accommodation space 130 so as to be foldable, and the length 601 of the projection when the folding arm 210 is deformed can be freely controlled.

Therefore, the access control device 1 can significantly reduce the width of the support frame 120 as compared with the conventional access door in which a door opening/closing passage of a predetermined size is used, and thus the installation width of the access control system 2 having a plurality of access control devices 1 can be reduced.

If the installation width of the access control system 2 is reduced, the number of access control devices 1 constituting the access control system 2 in a limited space increases, and therefore the number of users who use the access control system 2 for a predetermined time can be increased, which increases the processing capacity, which is a measure for evaluating the performance of the access control system 2.

Further, according to the present invention, since the installation width of the access control device 1 can be variously set, the access control device 1 suitable for various passage widths can be realized.

Further, the length 601 of the folding arm 210 of the opening/closing portion 200 that protrudes is greater than the linear lengths 602 and 701 by which the one end 213a of the second link 213 moves through the driving portion 300, and the driving speed of the opening/closing portion 200 is improved as compared with the driving speed of the conventional sliding door and swing door. If the driving speed of the access control device 1 is increased, the reliability and the economical efficiency of the access control device 1 are also improved.

The linear lengths 602 and 701 of the one end 213a of the second link 213 moved by the driving unit 300 being shorter than the length 601 of the folding arm 210 protruding means that the distance the driving unit moves the opening/closing unit is shorter than the width of the passage that the opening/closing unit actually moves to open and close. Therefore, compared to the conventional sliding door and swing door in which the distance by which the driving unit moves the opening/closing unit is the same as the width of the passage that the opening/closing unit actually moves to open and close, the durability of the driving unit 300 of the access control device 1 can be improved, and the energy efficiency of the access control device 1 can be improved.

The above description is only for illustrating the present invention, and it can be understood by those skilled in the art that the present invention can be easily modified into other specific forms without changing the technical idea or essential features. The above-described embodiments are, therefore, to be considered in all respects as illustrative and not restrictive. For example, elements described as singular may be implemented by being distributed, and similarly, elements described as distributed may be implemented by being combined. The scope of the present invention is defined by the appended claims, and all changes and modifications derived from the scope of claims and equivalents thereof are intended to be included in the scope of the present invention.
