Description

Technical Field

[0001] The invention relates to the field of access control and security, and in particular to an access control device. Background Art

[0002] Access control refers to the prohibition of door permissions. In a broad sense, doors refer to various accessible passages. Access control systems are also called passage access management and control systems. They are intelligent management systems for personnel or vehicles entering and exiting specific passages. Gates are a common access control device. They are a passage blocking device used to manage the flow of people and regulate the entry and exit of pedestrians. They are mainly used in subway gate systems, toll gate systems, etc. Their most basic core function is to allow only one person to pass through at a time. They can be used at the entrances of various toll and access control occasions.

[0003] Most of the gates in the prior art are infrared access control systems, which require a longer channel to be set up with a gate in the channel. The gate has an openable and closable barrier and multiple infrared sensor groups are installed in the channel to monitor the user's position in the channel and determine the real-time position of each user in the gate channel. Combined with user identity verification technology, the effect of only one person passing through at a time can be achieved.

[0004] The disadvantage of infrared gate machines is that each gate machine has a long channel and occupies a large space. A large number of infrared sensor groups are installed in the gate machine, and the hardware cost is high and the price is expensive. Summary of the invention

[0024] Access control devices are usually used at the exit or entrance of a closed space. According to the requirements of fire management, in special circumstances, such as a fire, the closed space needs to have one or more normally open safety passages. Therefore, the access control device also needs to have the function of keeping the door open for a long time under special circumstances.

[0058] The following fully describes the preferred embodiments of the present invention with reference to the drawings in the specification, so that the technical content is clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and its protection scope is not limited to the embodiments mentioned in the text.

[0059] In the drawings, components with the same structure are indicated by the same numerical labels, and components with similar structures or functions are indicated by similar numerical labels.

[0060] When some components are described as being "on" another component, the component may be directly placed on the other component; there may also be an intermediate component on which the component is placed, and the intermediate component is placed on the other component. When a component is described as being "mounted on" or "connected to" another component, the two may be understood to be directly "mounted on" or "connected" or one component may be indirectly "mounted on" or "connected to" another component via an intermediate component.

[0061] like Figures 1 to 3 As shown, this embodiment provides an access control device, also known as a gate machine, including a mounting base 1, a channel 2, a door panel 3, a rotating part 4, a locking device 5 and a thrust recovery device 6.

[0062] like Figure 1 As shown, the installation base 1 is a column fixed to the ground, the cross section of the column is an oblong, and the side wall of the column includes two opposite and parallel flat plates, namely, the installation plates 15.

[0063] In this embodiment, a passage 2 is formed on one side of the installation base 1, and the passage 2 includes a passage entrance and a passage exit; a door panel 3 is vertically arranged in the passage 2, perpendicular to the horizontal plane, and the width of the door panel 3 is slightly smaller than the width of the passage. When a door panel 3 is locked, the passage 2 where the door panel 3 is located is blocked by the door panel 3, and no one can pass through the passage at this time.

[0064] like Figure 2 As shown, a rotating member 4 is provided between the door panel 3 and the mounting base 1, and the door panel 3 is rotatably connected to the mounting plate 15 through the rotating member 4. When the door panel 3 is stationary, the plane where the door panel 3 is located is perpendicular to the surface of the mounting plate 15.

[0065] like Figure 3 As shown, the rotating member 4 includes a rotating shaft 41 , a connecting portion 42 and a locking portion 43 .

[0066] The central axis of the rotating shaft 41 is perpendicular to the horizontal plane, and the upper and lower ends of the rotating shaft 41 are rotatably connected to the mounting base 1; the access control device described in this embodiment includes two bases 44, which are fixed to the upper and lower ends of a mounting plate 15, and each base 44 is provided with a base through hole 45, and the base through holes 45 of the two bases are arranged opposite to each other; each base through hole 45 is provided with a bearing (not shown in the figure), and the two ends of the rotating shaft 41 are rotatably mounted in the two base through holes 45 through a bearing (not shown in the figure).

[0067] The connecting portion 42 includes a first connecting plate 421, a second connecting plate 422 and two arc plates 423. The first connecting plate 421 protrudes from the side wall of the rotating shaft 41 and forms an integrated structure with the rotating shaft 41. The second connecting plate 422 is connected to the first connecting plate 421 and connected to the door panel 3. Each arc plate 423 is a part of the side wall of a cylinder. The cross section of the arc plate 423 is an arc. The central angle of the arc is 90-120 degrees. The center of the arc is located on the central axis of the rotating shaft 41. Each arc plate 423 includes two straight edges away from each other, one of which is connected to the first connecting plate 421. The two arc plates 423 form a semicircular ring shape.

[0068] The locking portion 43 protrudes from the side wall of the rotating shaft 41. The locking portion 43 includes a locking plate 431 and a buffer plate 432 made of ferromagnetic metal. The locking plate 431 is connected to the side wall of the rotating shaft 41 and extends along a generatrix direction of the rotating shaft. The buffer plate 432 is made of elastic material and attached to the surface of the locking plate 431.

[0069] In this embodiment, the connecting portion 42 and the locking portion 43 are respectively disposed on both sides of the rotating shaft 41 , the locking plate 431 and the connecting portion 42 are located in the same plane, and the angle between the connecting portion 42 and the locking plate 431 is 180 degrees.

[0070] like Figure 2 , Figure 3 As shown, further, this embodiment further includes a limit plate 46 and a limit block 47. The limit plate 46 is connected to the side wall of the rotating shaft 41, and its extension direction is consistent with the first connecting plate 421. The limit block 47 is made of elastic material, protrudes from a mounting plate 15, and faces the direction of the door panel 3. When the door panel 3 is pushed open and rotated 90 degrees, the rotating shaft 41 is also rotated 90 degrees, and the limit plate 46 is blocked by the limit block 47 to prevent excessive rotation from causing the door panel 3 to hit the outer wall of the installation base 1, and to prevent the door panel 3 and other components from being damaged, so as to extend the service life of the access control device.

[0071] like Figure 4 As shown, in this embodiment, the locking device 5 is an electromagnetic lock, which is fixed to the mounting base 1 to lock or unlock the door panel 3. The locking device 5 includes an electromagnetic sheet 51, and the surface of one side of the electromagnetic sheet 51 is a magnetic surface 52, which is vertically connected to the outer wall of the mounting plate 15. When the electromagnetic sheet 51 is powered on, the locking portion 43 is adsorbed by the electromagnetic sheet 51, and the locking plate 431 is attached to the magnetic surface 52 through the buffer plate 432; when the electromagnetic sheet 51 is powered off, the locking portion 43 is separated from the electromagnetic sheet 51.

[0072] When a door panel 3 is locked, the door panel 3 is perpendicular to the mounting plate 15, and the passage 2 where the door panel 3 is located is divided into two parts by the door panel, the area near the passage entrance in the passage 2 is the entrance area, and the area near the passage exit in the passage 2 is the exit area. When a door panel 3 is unlocked, when the door panel 3 is subjected to a horizontal thrust from the passage entrance direction, the door panel 3 is pushed to rotate toward the exit direction, and the maximum rotation angle of the door panel 3 is 80-100 degrees, preferably 90 degrees, so that the passage 2 where the door panel 3 is located is unblocked, allowing users to pass through the passage 2.

[0073] Another function of the locking device 5 is to limit the rotation angle of the shaft 41 so that the door panel 3 can only rotate 90 degrees toward the exit but not toward the entrance, thereby making the access control device only able to open the door in one direction, and the user can only walk from the entrance of the passage to the exit but cannot open the door in the opposite direction or walk from the exit to the entrance.

[0074] like Figure 2 , Figure 5 As shown, the thrust recovery device 6 is used to connect the installation base 1 and the door panel 3. The thrust recovery device 6 is a door closer, which includes a housing 61, an elastic member (not shown) and a connecting rod 62.

[0075] The shell 61 is a cylinder having a cylindrical cavity therein. An elastic member (not shown) is respectively provided in the upper and lower halves of the cavity. In this embodiment, the elastic member is preferably a coil spring, the first end of which is fixed to the inner wall of the shell 61, such as the inner side wall, the inner top surface or the inner bottom surface, and the other end thereof is connected to the connecting rod 62.

[0076] The connecting rod 62 is a T-shaped rod, including a straight rod 621 and a bent rod 622. The straight rod 621 is vertically arranged in the cavity, and the upper end and the lower end of the straight rod 621 are respectively connected to the second end of the elastic member (coil spring). One end of the bent rod 622 extends into the cavity and is connected to the middle part of the straight rod 621, and the other end is hinged to the door panel 3.

[0077] like Figure 6 As shown, this embodiment also includes a touch-pressure switch 7, which is fixed to the surface of the mounting plate 15; the touch-pressure switch 7 includes a touch-pressure surface 71, the plane of the touch-pressure surface 71 is perpendicular to the mounting plate 15 and faces the passage entrance; when the door panel 3 is locked, the touch-pressure surface 71 is attached to the surface of a locking plate 431.

[0078] like Figure 7 As shown, this embodiment also includes a data processing device 100, which is a computer, including but not limited to a single-chip microcomputer, a PC or a server, for realizing the control of multiple electronic devices.

[0079] The data processing device 100 is connected to the touch pressure switch 7 and the locking device 5 through wires; when the touch pressure surface 71 of the touch pressure switch 7 is subjected to force, the touch pressure switch 7 generates an electrical signal; when the data processing device 100 receives the electrical signal generated by the touch pressure switch, the data processing device 100 sends a locking signal to a locking device 5 to lock the door panel 3.

[0080] When the door panel 3 is pushed, the elastic member is subjected to elastic deformation to collect the thrust. When the door panel 3 loses the thrust, the thrust recovery device 6 drives the door panel 3 to rotate in the opposite direction of the force direction mentioned above until the door panel 3 is locked by the locking device 5 again. During this process, the elastic member returns to its original state and drives the door panel 3 to reset through the connecting rod 62.

[0081] When the door panel 3 returns to the initial position, the contact pressure surface 71 is pressed by the surface of the locking plate 431, and an electrical signal is sent to the data processing device 100, and the data processing device 100 sends a locking signal to a locking device 5, and the electromagnetic sheet 51 of the locking device 5 is powered on again, the locking portion 43 is adsorbed by the electromagnetic sheet 51, and the locking plate 431 is again attached to the magnetic surface 52 through the buffer plate 432, and the passage 2 is again blocked. In some special cases, the door panel 3 is manually closed, and the touch pressure switch 7 can also be triggered to close the door panel 3.

[0082] like Figure 7 As shown, the access control device described in this embodiment also includes an entrance sensor 101, which is connected to the data processing device 100 via a wire.

[0083] The entrance sensor 101 determines whether there is a user at the entrance of the passage 2, and if so, outputs an electrical signal (first signal) to the data processing device 100. When the data processing device 100 receives the first signal from the entrance sensor 101, the data processing device 100 sends an unlocking signal to the locking device 5 to unlock the door panel.

[0084] The entrance sensor 101 includes but is not limited to an infrared sensor or a camera, which is installed at the entrance of the passage 2 or in front of the passage entrance. The infrared sensor can be installed on the side wall of the installation base 1, facing the direction of the passage 2, and the infrared sensor can sense when there is someone at the entrance of the passage 2. The camera is installed on the top or ceiling of the installation base 1, facing the entrance area of ​​the passage 2 or in front of the passage entrance. The camera can determine whether there is someone in the entrance area by image comparison.

[0085] In other embodiments, a channel 2 may be formed on both sides of the installation base 1. A set of door panels 3, a rotating member 4, a locking device 5 and a thrust recovery device 6 are respectively arranged on both sides of the installation base 1.

[0086] The access control device described in this embodiment is suitable for one-way channel scenarios where user identity verification is not required, such as the exit of a train station waiting room, the exit of an unmanned convenience store, and the like.

[0087] The advantage of this embodiment is that, compared with the prior art, the solution of this embodiment can set the passage to be extremely short, which is only equivalent to a conventional door frame, thereby minimizing the footprint of the entire access control device. This embodiment is provided with a thrust recovery device, which can open the door when the user pushes the door panel, and can automatically close the door after the user passes, which is convenient to use.

[0088] Example 2

[0089] like Figure 8-9 As shown, Example 2 includes most of the technical features of Example 1. The first difference between Example 2 and Example 1 is that the access control device described in this embodiment does not include an entrance sensor 101, but includes an identity verification device 102, and the data processing device 100 is electrically connected to the locking device 5 and the identity verification device 102 through a wire. Other components of this embodiment not mentioned in the above text are the same as those of Example 1 and are not described here.

[0090] The identity verification device 102 is used to identify the identity of the user and determine whether the user has the authority to pass through the passage. If so, a second signal is output to the data processing device 100. When the data processing device 100 receives the second signal, the data processing device 100 sends an unlocking signal to the locking device 5 to unlock the door panel 3.

[0091] The identity verification device 102 includes but is not limited to an RFID reader, a fingerprint reader, and a camera, and is located at the entrance of the passage 2, facing the user. That is, the user can use a card with an RFID chip inside to swipe the card for identity verification; can use fingerprint recognition to pass identity verification; can also use a graphic code scanning method or a face recognition method to pass identity verification.

[0092] Users need to verify their identity before passing through this channel. This embodiment can be applied to scenarios where identity verification is required, such as the entrance to a station waiting room, the entrance to an unmanned convenience store, etc.

[0093] like Figure 8 As shown, the second difference between Example 2 and Example 1 is that the access control device described in Example 2 also includes a second door panel 13, which is installed in a channel 2; the second door panel 13 is perpendicular to the horizontal plane and vertically connected to the door panel 3; the second door panel 13 extends toward the entrance direction of the channel 2.

[0094] In the actual application of the access control system, when faced with a channel that requires identity authentication, some users without permission will follow the previous user with permission.

[0095] The door panel 3 and the second door panel 13 always maintain an angle of about 90 degrees, forming a semi-enclosed space. When a user passes through the access control device channel, he is always in this semi-enclosed space, and the person behind the user always keeps a certain distance from the user. When the door panel is closed, the user behind cannot enter the channel 2, so the technical effect of anti-tailgating can be effectively achieved.

[0096] Except for the two differences mentioned above, other components of this embodiment not mentioned above are the same as those of Embodiment 1 and will not be described in detail here.

[0097] The advantage of this embodiment is that, compared with the prior art, this embodiment can set the channel to be extremely short, which is only equivalent to a regular door frame, thereby minimizing the footprint of the entire access control device. This embodiment is provided with a user identity verification device, which can identify the user's identity and verify whether the user has the right to pass through, and only allow users with the right to pass through. The access control device described in this embodiment is suitable for one-way channel scenarios where user identity verification is required, such as the entrance to a train station waiting room, the entrance to an unmanned convenience store, and the like.

[0098] Example 3

[0099] Embodiment 3 includes all technical solutions of Embodiment 1 and / or Embodiment 2. The access control device of Embodiment 3 includes an entrance sensor 101 and / or an identity verification device 102. A channel 2 is arranged on one side of the installation base 1, or a channel 2 is arranged on both sides of the installation base 1.

[0100] like Figure 10-11 As shown, when a channel 2 is set on each side of the installation base 1, one of the two channels 2 can be used as a space entrance, and it is necessary to verify whether the user has the authority to pass through the channel, and only authorized users can pass through; the other can be used as a space exit, and users can pass through without verifying the user's authority. This embodiment can be applied to the entrance and exit of a train station waiting room, the entrance and exit of an unmanned convenience store, and so on.

[0101] In the actual application of door panel access control equipment, there will be some special situations. Some users will ignore the passage rules and hope to move from the exit to the entrance of the passage, or users without passage authority will follow the previous user with passage authority. They will use force to open the door panel again before the door panel is closed and pass through the passage. Even if the door panel can only be opened to the exit, this situation cannot be completely eliminated, because the door panel may be opened a second time by someone before it is closed and locked.

[0102] To solve this problem, further Figure 12-14 As shown, the access control device described in Example 3 also includes a ratchet 8 and a pawl 9.

[0103] like Fig.12 As shown, the ratchet wheel 8 is fixed to the top or bottom of a rotating shaft 41 , and the central axis of the ratchet wheel 8 is located on the same straight line as the central axis of the rotating shaft 41 ; the side surface of the ratchet wheel 8 is provided with uniformly distributed one-way gear teeth 81 .

[0104] like Figure 13-14 As shown, the pawl 9 is rotatably mounted to a mounting plate 15 , and the pawl 9 includes a first arm 91 and a second arm 92 connected to each other, and the angle between the first arm 91 and the second arm 92 is 90-135 degrees.

[0105] like Fig.13 As shown, the front end of the first arm is provided with a stop pawl 93, which can be inserted into the gap between the one-way gear teeth 81 of the pawl 9. At this time, the ratchet 8 is restricted and cannot rotate clockwise; when the ratchet 8 is rotated counterclockwise, the stop pawl 93 can slide along the back of the one-way gear teeth 81. When a door panel loses the horizontal thrust, the ratchet 8 connected to the door panel is engaged by the pawl 9; when the door panel is locked again, the ratchet 8 connected to the door panel is separated from the pawl 9.

[0106] like Fig.13 As shown, in Embodiment 3, the mounting plate 15 is provided with a first through hole 110 penetrating the side wall, which is a square hole, and the height of the center of the first through hole 110 on the mounting plate 15 is consistent with or similar to the height of the ratchet 9 .

[0107] like Fig.13As shown, a pawl bracket 10 and a first stepper motor 11 are respectively provided on both sides of the mounting plate 15. The pawl bracket 10 is fixedly mounted to the outer side of the mounting plate 15 and is located above the first through hole 110; the first stepper motor 11 is fixed to the inner side of the mounting plate 15, and its height is consistent with the center of the first through hole 110. The first stepper motor 11 includes a first telescopic rod 111 that can be extended and retracted in the horizontal direction.

[0108] like Fig.14 As shown, the connection between the first arm 91 and the second arm 92 is hinged to the pawl bracket 10, the end of the second arm 92 is connected to the movable end of the first telescopic rod 111, and the first stepper motor 11 is connected to the data processing device 100. The data processing system 100 controls the ratchet 8 to be engaged or released by controlling the telescopic length of the first telescopic rod 111.

[0109] When the first telescopic rod 111 is shortened, the locking claw 93 is engaged in the gap between the one-way gear teeth 81; at this time, the rotating member 4 can only be rotated in one direction. When the first telescopic rod 111 is extended, the locking claw 93 is disengaged from the ratchet 8, and the rotation direction of the rotating member 4 is not restricted.

[0110] When the data processing device 100 receives the first signal or the second signal, the data processing device 100 sends an unlocking signal to the locking device 5 to unlock the door panel 3, so that the door panel 3 can be pushed by the user, and the user pushes the door panel 3 to pass through the passage 2. When the door panel 3 rotates 90 degrees, its rotation angle is the largest. After the user passes through the passage 2, the door panel 3 loses the thrust and automatically resets to the initial position.

[0111] When the door panel 3 loses its thrust, the data processing device 100 sends an electrical signal to the first stepper motor 11, so that the stop pawl 93 is inserted into the gap between the one-way gear teeth 81 of the ratchet 9. At this time, the rotating member 4 can only be rotated in one direction, and the door panel 3 can only be rotated toward the entrance direction, and can only be closed, and cannot be opened again, effectively preventing unauthorized users from opening the door again and passing through the passage in the forward or reverse direction.

[0112] When the door panel 3 returns to its initial position, the contact surface 71 is pressed by the surface of the locking plate 431, and the contact switch 7 sends an electrical signal to the data processing device 100. The data processing device 100 sends a locking signal to a locking device 5. The electromagnetic sheet 51 of the locking device 5 is energized again, and the locking portion 43 is adsorbed by the electromagnetic sheet 51. The door panel 3 again blocks the passage 2.

[0113] When the door panel 3 returns to the initial position, the touch switch 7 sends an electrical signal to the data processing device 100, and the data processing device 100 further sends an electrical signal to the first stepper motor 11. After receiving the electrical signal, the first stepper motor 11 controls the telescopic rod 111 to extend, so that the locking claw 93 is disengaged from the ratchet 8.

[0114] When the data processing device 100 receives the first signal or the second signal again, the data processing device 100 sends an unlocking signal to the locking device 5 . Since the locking claw 93 is disengaged from the ratchet 8 , the user can easily push the door panel 3 .

[0115] The advantage of this embodiment is that, compared with the prior art, this embodiment can set the passage to be extremely short, which is only equivalent to a conventional door frame, thus minimizing the footprint of the entire access control device. In this embodiment, when the door panel is pushed, it rotates toward the exit; when the door panel loses the push, it can only rotate toward the entrance. Before the door panel is closed and locked, it cannot be opened a second time, preventing unauthorized users from opening the door a second time and passing through the passage, effectively achieving the technical effects of preventing retrograde and tailgating.

[0116] Example 4

[0117] like Figure 15-17 As shown, Example 4 includes all the technical features of Example 1. The difference between Example 4 and Example 1 is that the access control device described in Example 4 also includes a second locking device 14. When the door panel 3 is parallel to the mounting plate 15, the door panel 3 is pushed open to a maximum angle of 90 degrees, and the rotating member 4 is locked by the second locking device 14, so that the door panel 3 remains stationary, so that the passage where the door panel 3 is located remains unobstructed.

[0118] like Fig.15 As shown, the mounting plate 15 is provided with a second through hole 120, which is a waist-shaped hole, and the height of the center line of the second through hole 120 is lower than the height of the lower edge of a locking plate 431. The second locking device 14 and the second stepping motor 12 are respectively arranged on the inner and outer sides of the mounting plate 15 near the second through hole 120.

[0119] The second locking device 14 is fixed to the outside of the mounting plate 15 through a bracket, and the second stepper motor 12 is fixed to the inside of the mounting plate 15. The second stepper motor 12 includes a second telescopic rod 121 that can be telescopic in the vertical direction.

[0120] like Figure 15-16 As shown, the second locking device 14 is a limit box, which includes a box body 141 , a slider 142 and a slide rod 143 .

[0121] The box body 141 includes a cavity; the slider 142 is arranged in the cavity and is hinged to two opposite inner walls of the box body 141, and a protrusion 144 is provided at the upper end of the slider 142, which can protrude from the upper edge of the box body 141; one end of the sliding rod 143 is connected to the side wall of the slider 142, and the other end thereof passes through the second through hole 120 and is connected to the movable end of the second telescopic rod 121.

[0122] The second stepper motor 12 is connected to the data processing device 100; when the passage 2 of the access control device needs to remain unobstructed for a long time, the staff or user can first push the door panel 3 to the maximum angle, i.e. 90 degrees, and then control the second locking device 14 to lock the door panel 3 by issuing instructions through the data processing device 100.

[0123] After the door panel 3 is parallel to the mounting plate 15 , the data processing device 100 sends an electrical signal to the second stepping motor 12 to shorten the length of the second telescopic rod 121 . The end of the slider 142 away from the slide bar 143 is raised and abuts against the surface of the locking plate 431 .

[0124] like Figure 2 and Fig.15 As shown, the rotating member 4 includes a locking plate 431 and a limiting plate 46, which are respectively connected to the side walls of the rotating shaft 41 and extend in opposite directions, and the angle between the locking plate 431 and the limiting plate 46 is 180 degrees. When the door panel 3 is pushed open to the maximum angle, the rotating shaft 41 rotates 90 degrees relative to the initial state. At this time, the limiting plate 46 is abutted by the limiting block 47. If the locking plate 431 is also abutted by the slider 142 at the same time, the rotating member 4 will be locked and cannot be rotated, and the door panel 3 will also be fixed, so that the passage remains unobstructed.

[0125] The other components of this embodiment not mentioned in the above text are exactly the same as those of embodiment 1, and are not described here in detail. The access control device described in this embodiment is suitable for one-way channel scenarios where user identity verification is not required, such as the exit of a train station waiting room, the exit of an unmanned convenience store, etc. In other embodiments, the technical features described in embodiment 4 can also be applied to the solution of embodiment 2.

[0126] The advantage of this embodiment is that, compared with the prior art, this embodiment can set the passage to be extremely short, which is only equivalent to a conventional door frame, thereby minimizing the footprint of the entire access control device. The access control device described in this embodiment can keep the door open for a long time under special circumstances, and various application scenarios of the access control device can meet the requirements of fire management and effectively improve safety.

[0127] The present invention provides a door control device, which can set a passage to be extremely short, thereby reducing the floor space of the entire door control device to the greatest extent. The present invention is provided with a thrust recovery device, which can open the door when the user pushes the door panel, and can automatically close the door after the user passes, which is convenient to use.

[0128] The present invention is provided with an anti-retrograde device. When the door panel loses thrust, it can only rotate toward the entrance direction and cannot be opened again before the door panel is closed, preventing unauthorized users from opening the door again, and effectively achieving the technical effect of anti-retrograde. The present invention is provided with two door panels perpendicular to each other, providing each user with a relatively independent space, effectively achieving the technical effect of anti-tailgating.

[0129] The present invention combines a data processing device with an identity authentication device or an entry detection device, and can be applied to various one-way channel scenarios that require or do not require verification of user permissions. It has low cost, is easy to promote and apply on a large scale, and has good market prospects.

[0130] The above description is only a preferred embodiment of the present invention, so that those skilled in the art can more clearly understand how to practice the present invention, and these embodiments do not limit the scope of the present invention. For those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
