Technical Field

The present invention relates to an entrance and exit control device, and more particularly, to an entrance and exit control device using a linear (linear) motor and a multi-stage door to improve durability and to adjust an installation width.

Background

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. Further, the swing door is configured such that the door is rotated about a rotation shaft, which causes a safety problem, for example, a user may hit the door. Therefore, recently, a sliding door, which is superior in safety to a swing door in that the door can automatically slide, is frequently used.

In addition, one of the main benchmarks for evaluating the access door performance is the 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 main 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. Also, the structure of sliding the door D left and right has a limitation to increase the driving speed of the door.

Further, as described above, since the conventional access door has a structure in which a door having a predetermined size is coupled to the door main body, it is fundamentally impossible to freely adjust the installation width of the access door.

In addition, the conventional sliding door is configured to control the door (D of fig. 1) by driving the link (20 of fig. 1) using the rotary motor (50 of fig. 1). That is, in the conventional sliding door, in order to slide the door (opening/closing portion) using the rotary motor, components such as pulleys (32, 32' of fig. 1), links (20 of fig. 1), and the like are additionally required, which causes overload of the motor. As a result, the conventional sliding door has disadvantages such as shortening the life of the motor and weakening the durability of the entire door.

Therefore, a sliding door having a new structure capable of solving such many technical problems of the conventional sliding door is required in the entrance and exit industry.

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 and exit control device 1 for a control passage includes a door body 100, an opening and closing unit 200, a driving unit 300, and may further include an identification unit 400, a guide unit 500, a user number measuring unit 600, and a communication unit 700, and additionally includes a power source (not shown), a battery (not shown), and a speaker (not shown).

The door main body 100 is provided in the passage to form an external shape of the access control apparatus 1, and supports, protects and accommodates each component.

The opening and closing part 200 is coupled to the door main body 100, and has a door 210 having a multi-stage structure that can be slid doubly, and opens and closes a passage by a transformation between an open mode and a closed mode.

The driving part 300 is combined with the door main body 100 and the opening and closing part 200, drives the opening and closing part 200 and controls the operation of the opening and closing part 200. The opening/closing unit 200 is coupled to the driving unit 300 to form an integrated unit 2030.

Fig. 4 is a view showing various modified embodiments of the door main body 100 of one embodiment of the present invention, and 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 case that the support frame 120 is separately provided at the passage or the additional support body 401 at the lower end of a of fig. 4 as in a of fig. 4, the provision of the shelf 110 is not a necessary component.

However, in the case that the support frame 120 has a circular structure or cannot be separately installed in the passage or the support body 401 as shown in b of fig. 4, the installation frame 110 is installed in the passage or the support body 401, and the support frame 120 may be connected to the installation frame 110.

As shown in fig. 4, the configuration and shape of the setting frame 110, the supporting frame 120 and the accommodating space 130 may be various, but not limited thereto, and the supporting frame 120 has a vertical structure in a of fig. 4 and a circular structure in b of fig. 4, but the supporting frame 120 does not necessarily have to have a vertical structure or a circular structure.

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.

When the opening/closing portion 200 and the driving portion 300 are simultaneously inserted into the accommodating space 130, the opening/closing portion 200 and the driving portion 300 are coupled to each other to form the integrated unit 2030 in order to improve space efficiency.

The access control device 1 may have more than one (one or more) integrated unit 2030.

The storage space 130 is formed in a partially or wholly detachable or insertable manner of the integrated unit 2030 to which the opening/closing portion 200 and the driving portion 300 are coupled. Accordingly, the accommodating space 130 may have various sizes, and thus, the width of the support bracket 120 having the accommodating space 130 may be freely set.

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.

The opening/closing portion 200 and the driving portion 300 may constitute an integrated unit 2030, the integrated unit 2030 may be inserted into or detachably installed in the receiving space 130, and the door main body 100, the opening/closing portion 200, the driving portion 300, and the respective lower components may be assembled. Therefore, the access control device 1 can increase the convenience of installation and replacement of parts.

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 200. The opening/closing section 200 of the access control device 1 and the opening/closing operation of the access control device 1 by the opening/closing section 200 and the driving section 300 will be described in detail with reference to fig. 2 to 7.

Referring first to fig. 2 and 6, the driving part 300 may have a linear motor 310.

A general linear motor is mainly applied to a motor of a magnetic levitation train, has a structure like an induction motor which is spread on a plane cut along an axis, is composed of a reaction rail such as a stator, and is a motor which generates a linear driving force in a track direction.

As described above, the driving part 300 controls the operation of the opening and closing part 200 using the linear motor 310, and the driving part 300 makes the opening and closing part 200 perform a translational motion using the characteristics of the linear motor 310 when the opening and closing part 200 is changed into the open or closed mode.

Translational motion is the motion of all points of a mass point system moving in parallel with the same displacement, and is the opposite concept to rotational motion, and may be referred to as linear motion.

Because the prior sliding door uses a rotary motor, the door can not do translational motion but do curvilinear motion or rotary motion. Since the durability of the door opening/closing portion is weakened as described above if the door opening/closing portion moves in a curve or in a rotation, the access control device 1 causes the opening/closing portion 200 to move in a translation manner by the linear motor 310.

Further, since the linear motor 310 uses magnetism, an additional contact portion is not required when power is transmitted. Accordingly, the linear motor 310 also has an effect that there is no concern about deterioration in durability due to friction. With this configuration, the access control device 1 can increase the opening/closing driving speed of the opening/closing portion 200 in addition to the durability.

Next, the door 210 having the multi-stage structure of the opening and closing part 200 may include a first door 211 driven by the linear motor 310 and a second door 213 coupled to the first door 211 to be interlocked with the first door 211.

In other words, the gate 210 of the multi-stage structure may include a first gate 211 combined with the driving part 300 and a second gate 213 overlappingly combined with the first gate 211.

The first gate 211 and the second gate 213 may be the same in size and shape, but may also have different shapes and sizes, respectively. The first door 211 and the second door 213 may be fabricated in a quadrangular panel shape, but need not be.

The access control device 1 has a door 210 having a multi-stage structure including a first door 211 and a second door 213, and can reduce the size of the support frame 120 and the size of the housing space 130. Therefore, the access control device 1 has an effect of being able to reduce the overall size and installation width of the access control device 1.

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

Specifically, the linear motor 310 is coupled to the first door 211 to control the first door 211 such that the first door 211 slides on the accommodating space 130.

In order to implement the dual sliding type, the second door driving module 320 is disposed to surround the second door 213, and functions to control the second door 213 such that the second door 213 slides on the first door 211.

And, the second door driving module 320 may additionally have a power transmission unit 321 such that the second door 213 slides on the first door 211.

In addition, the power transmission unit 321 may have a belt type power transmission structure. Accordingly, the power transmission unit 321 achieves natural sliding of the second door 213 on the first door 211 in a pulley manner using a belt type power transmission structure.

As described above, the door 210 having the double sliding structure and the multi-stage structure can improve space efficiency and increase the variety of opening and closing methods of the opening and closing part 200.

In addition, although not shown in the drawings, other embodiments of the present invention are connected in such a manner that a third door, a fourth door, etc. are overlapped and combined with the second door and the third door, respectively, thereby implementing a multiple sliding structure. If the multiple sliding system is realized by the stacked structure, the space efficiency can be further improved.

Next, the closing mode and the opening mode of the opening and closing part 200 of the door 210 having a multi-stage structure capable of double sliding will be described in detail.

When the opening/closing unit 200 is closed by the driving unit 300, the linear motor 310 controls the first door 211 to slide outward (outward) of the accommodating space 130 as shown at 601 in fig. 6, the second door driving module 320 controls the second door 213 to slide outward (wall direction indicated by X in fig. 6) of the first door 211 as shown at 602 in fig. 6.

When the opening/closing unit 200 is opened by the driving unit 300, the linear motor 310 controls the first door 211 to slide in the housing space 130 as shown by 701 in fig. 7, and the second door driving module 320 controls the second door 213 to slide in the inner direction of the first door 211 (the direction opposite to the wall indicated by X in fig. 7) as shown by 702 in fig. 7.

Also, the time and method for the operation of the first door 211 based on the linear motor 310 and the operation of the second door 213 based on the second door driving module 320 may be different.

For example, a first door control event in which the linear motor 310 slides the first door 211 on the accommodating space 130 and a second door control event in which the second door driving module 320 slides the second door 213 on the first door 211 may occur simultaneously, or one of the first door control event and the second door control event may occur earlier than the other.

That is, when the opening and closing part 200 is opened and closed, the linear motor 310 and the second door driving module 320 may be simultaneously operated, or the linear motor 310 may slide the first door 211 prior to the second door driving module 320 or the second door driving module 320 may slide the second door 213 prior to the linear motor 310 at a predetermined time interval.

In various embodiments of the present invention, the time and speed at which the linear motor 310 slides the first door 211 and the time and speed at which the second door driving module 320 slides the second door 213 are differently set, respectively, thereby increasing the variety of opening and closing methods and also providing the access control device 1 having an excellent design.

Fig. 8 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. 8.

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 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.

Further, when the comparison results do not coincide, the recognition part 400 may also provide a preset sound through a speaker (not shown). For example, when the comparison result of the recognition unit 400 is not consistent, the access control device 1 may provide a voice such as "unauthorized user" or "please re-recognize" through a speaker (not shown).

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. 9 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 guide part 500 guides the sensed user to enter the access control apparatus 1 by using the entry guide 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 sequence, 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 the user measured by the first and second sensing modules 510 and 520 with the distance to another user, and guides the entry of the user and the other user into the access control device 1 by the entry 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 800 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 main body 100 opening and closing unit 200, the driving unit 300, the identification unit 400, the guide unit 500, the user measurement unit 600, and the communication unit 700 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 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 identifying the user by the identifying unit 400, and the information on the number of times of guiding the user by the guiding 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 at least one of 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, and the communication unit 700, driving frequency information of the opening/closing unit 200, user identification frequency information of the identification unit 400, 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 800 may display information related to the access control apparatus 1 by a display module (not shown in the drawings). The control unit 800 may monitor information related to the access control device 1 by using separate software, or may change the settings of the respective components constituting the access control device 1.

For example, the control unit 800 may change the mode of the opening/closing unit 200, set and change the identification method of the identification unit 400, set and change the guidance method of the guidance unit 500, transmit information to a preset terminal through the communication unit 700, set and change an audio provided by a speaker (not shown) provided in the access control device 1, acquire and display error information of each component constituting the access control device 1, and the like.

By transmitting and receiving information through the communication unit 700, the predetermined terminal can perform information analysis, management, and error analysis on the access control device 1. 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 800 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. 10 is a diagram showing an access control system 2 having 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 the foregoing description of fig. 2 to 9 and fig. 10.

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

The access control system 2 controls the sliding length of the first door 211 sliding on the housing space 130 and the sliding length of the second door 213 sliding on the first door 211, which are provided in each of the access control devices 1, to set the predetermined interval.

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.

When the access control device 1 described above is used, the sliding length of the first door 211 sliding on the housing space 130 and the sliding length of the second door 213 sliding on the first door 211 are set separately by the opening/closing section 200 of the door 210 having a multi-stage structure capable of double sliding.

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, as described above, since the access control device 1 controls the operation of the opening/closing portion 200 by the driving portion 300 having the linear motor 310 instead of the rotary motor, the driving speed of the opening/closing portion 200, that is, the opening/closing speed can be increased, and the durability of the access control device 1 and the access control system 2 as a whole can be improved. The reliability and economy of the access control device 1 can be improved by improving the durability of the access control device 1.

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.
