Description

Technical Field

[0001] This utility model relates to the field of access control equipment technology, and specifically discloses a fully automatic access control device for smart parks. Background Technology

[0002] With the advancement of information technology and changes in social needs, a new model of intelligent management and service for industrial parks using next-generation information technology—the smart park—has been gradually established. The smart park utilizes modern information technology such as the Internet of Things, cloud computing, and big data to achieve comprehensive intelligent management of personnel, materials, equipment, and environment within the park. Among these, access control equipment is mainly used for personnel management.

[0003] For example, patent CN218240992U, published on January 6, 2023, discloses an intelligent access control gate with facial recognition capability. The device consists of two sets of horizontally mounted devices at the same height. An electromagnetic card reader is horizontally mounted on one side of the top of each device, and a rotating rod is vertically mounted on one side of the top center of each device. An angle adjustment box is fixedly mounted at the top of each rotating rod, and an adjustment rod is horizontally mounted at the center of the front of each angle adjustment box. A facial recognition device is fixedly mounted at one end of each adjustment rod. This intelligent access control gate with facial recognition capability uses infrared detectors added to both sides of the access control post. If the gate is not opened by the first drive motor and the rotating rod when a pedestrian is detected, an alarm is triggered. A camera mounted on the top of the device monitors the situation. This method prevents unauthorized personnel from entering the community and causing adverse effects.

[0004] The shortcomings of existing access control devices, including the aforementioned patents, are that they cannot control the following phenomenon when people enter and exit during actual use. During use, people without authorization can enter with the person in front of them while the gate is closing. At the same time, it is impossible to achieve personnel control. Furthermore, the gate is prone to trapping the following person during the closing process, which can damage the gate connection. Utility Model Content

[0005] The purpose of this invention is to provide a fully automatic access control device for smart parks that can prevent people from following others into the park.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A smart park fully automatic access control device includes two sets of parallel fixed bases with a passage between them. A facial recognition device is installed on one of the fixed bases. A first barrier gate and a second barrier gate are sequentially arranged along the length of the passage between the two fixed bases. A camera is installed on one of the fixed bases. A driving component is installed in both sets of fixed bases. The driving component drives the first barrier gate to open based on the recognition result of the facial recognition device, and drives the second barrier gate to open based on the monitoring result of the camera.

[0008] The aforementioned fully automatic access control equipment has the first and second barriers respectively installed on fixed bases near both ends of the passage.

[0009] The aforementioned fully automatic access control equipment includes a first barrier gate comprising a left barrier and a right barrier. The left barrier is rotatably mounted on a set of fixed bases, and the right barrier is rotatably mounted on another set of fixed bases. The second barrier gate has the same structure as the first barrier gate, with the left and right barriers respectively connected to their corresponding drive components.

[0010] The aforementioned fully automatic access control equipment includes a motor installed in each fixed base. A rotating shaft is installed in each of the two fixed bases. The output end of the motor is connected to the rotating shaft, and the two ends of the rotating shaft are respectively connected to the corresponding left or right gate.

[0011] The aforementioned fully automatic access control equipment includes a first shaft and a second shaft with overlapping axes. The first shaft and the second shaft are connected by a power adjustment component. The power adjustment component is driven to move, so that the motor drives the first shaft and the second shaft to rotate synchronously or independently.

[0012] The aforementioned fully automatic access control device includes a power adjustment component comprising a transmission sleeve and a drive unit. The transmission sleeve is fitted outside the first shaft and the second shaft, and an internal gear is provided inside the transmission sleeve. A first gear is fixedly connected to one end of the first shaft and the second shaft corresponding to the transmission sleeve. The first gear cooperates with the internal gear, and the drive unit drives the transmission sleeve to move axially along the first shaft.

[0013] In the aforementioned fully automatic access control equipment, both the left and right gates are rotatably connected to their corresponding fixed seats via rotating shafts. A first torsion spring is fitted on the rotating shaft of both the left and right gates corresponding to the first gate, and a second torsion spring is fitted on the rotating shaft of both the left and right gates corresponding to the second gate. The first torsion spring causes the left and right gates of the first gate to tend to open, and the second torsion spring causes the left and right gates of the second gate to tend to close.

[0014] In the aforementioned fully automatic access control equipment, the output shaft of the motor is fixedly connected to a second gear, and an external gear is provided on the outside of the transmission sleeve. During the stroke of the transmission sleeve moving axially along the first shaft, the second gear remains engaged with the external gear.

[0015] The aforementioned fully automatic access control device includes an electric push rod installed in a fixed base. The electric push rod is arranged parallel to the first axis, and the output end of the electric push rod is rotatably connected to the transmission sleeve through a connector.

[0016] The aforementioned fully automatic access control equipment includes a connecting component comprising an adjusting ring rotatably mounted on one end of a transmission sleeve, a connecting block fixedly connected to the outer wall of the adjusting ring, and the output end of an electric push rod fixedly connected to the connecting block.

[0017] In the above technical solution, the fully automatic access control device provided by this utility model sets a first barrier and a second barrier between two fixed seats, and sets a facial recognition device and a camera. In actual use, the facial recognition device determines whether the person passing through has the right to pass and controls the opening or keeping the first barrier closed. The camera monitors the number of people between the first barrier and the second barrier and controls the opening or keeping the second barrier closed. The second barrier is only opened to allow passage when there is only one person between the first barrier and the second barrier, thereby avoiding the phenomenon of people following each other when entering and exiting, and preventing the barrier from being damaged due to the following person being caught in the closing process.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figures 1-6 As shown in the figure, the present invention provides a fully automatic access control device for a smart park, including two sets of parallel fixed seats 1, with a channel 2 between the two fixed seats 1. A facial recognition device 11 is installed on one of the fixed seats 1. A first barrier gate 3 and a second barrier gate 4 are arranged sequentially along the length of the channel 2 between the two fixed seats 1. A camera 12 is installed on one of the fixed seats 1. A driving component is provided in both sets of fixed seats 1. The driving component drives the first barrier gate 3 to open according to the recognition result of the facial recognition device 11, and drives the second barrier gate 4 to open according to the monitoring result of the camera 12.

[0030] Specifically, such as Figure 1 and Figure 2As shown, two fixed seats 1 are rectangular and arranged parallel to each other, with a passage 2 for personnel to pass through between them. A facial recognition device 11 is installed on each fixed seat 1 for identifying personnel information; this is prior art and will not be described in detail. The difference from prior art is that a camera 12 is installed on each fixed seat 1, and a first barrier gate 3 and a second barrier gate 4 are also installed on each fixed seat 1. The facial recognition device 11 is installed on the side of its respective fixed seat 1 corresponding to the first barrier gate 3. The camera 12 is used to monitor the number of personnel between the first barrier gate 3 and the second barrier gate 4. Each fixed seat 1 contains a drive mechanism for opening and closing the first barrier gate 3 and the second barrier gate 4. This fully automatic access control device also includes a processor. The recognition results of the facial recognition device 11 and the monitoring results of the camera 12 are fed back to the processor. The processor controls the drive mechanism to open the first barrier gate 3 or the second barrier gate 4 based on the recognition and monitoring results. Preferably, the first barrier gate 3 and the second barrier gate 4 are respectively located on the fixed seat 1 near both ends of the passage 2. Figure 2 As shown, this provides sufficient space between the first barrier 3 and the second barrier 4 for people to stand.

[0031] When in use, the fully automatic access control device uses a facial recognition device 11 to recognize a person's image and feed the recognition result back to the processor. The processor determines whether the person has permission to pass through the first barrier gate 3. When the person has permission, the processor controls the drive unit to open the first barrier gate 3. After the person enters the channel 2, the camera 12 monitors the number of people between the first barrier gate 3 and the second barrier gate 4 and feeds the result back to the processor. Only when the number of people is one, the processor controls the drive unit to open the second barrier gate 4. This setting can prevent people from tailgating in.

[0032] The fully automatic access control device provided in this embodiment of the utility model sets a first barrier 3 and a second barrier 4 between two fixed seats 1, and sets a facial recognition device 11 and a camera 12. In actual use, the facial recognition device 11 determines whether the person passing through has the right to pass and controls the opening or keeping the first barrier 3 closed. The camera 12 monitors the number of people between the first barrier 3 and the second barrier 4 and controls the opening or keeping the second barrier 4 closed. The second barrier 4 is only opened to allow passage when there is only one person between the first barrier 3 and the second barrier 4, thereby avoiding the phenomenon of people following each other when entering and exiting, and preventing the barrier from being damaged due to the following person being caught in the closing process.

[0033] Furthermore, the first barrier gate 3 includes a left gate plate 31 and a right gate plate 32. The left gate plate 31 is rotatably mounted on a set of fixed seats 1, and the right gate plate 32 is rotatably mounted on another set of fixed seats 1. The second barrier gate 4 has the same structure as the first barrier gate 3. The left gate plate 31 and the right gate plate 32 are respectively connected to the corresponding driving components. By using the cooperation of the left gate plate 31 and the right gate plate 32, the width of the gate is reduced. The speed of opening or closing of the first barrier gate 3 and the second barrier gate 4 is increased by rotating the left gate plate 31 and the right gate plate 32 simultaneously.

[0034] Furthermore, the driving component includes a motor 6 installed in each fixed base 1. A rotating shaft 5 is installed in each of the two fixed bases 1. The output end of the motor 6 is connected to the rotating shaft 5. The two ends of the rotating shaft 5 are respectively connected to the corresponding left gate 31 or right gate 32. In this embodiment, the number of motors 6 is the same as the total number of left gates 31 and right gates 32. That is, the motor 6 drives a single left gate 31 or a single right gate 32 to rotate, so as to achieve the purpose of controlling the opening or closing of the first gate 3 and the second gate 4.

[0035] In another embodiment of this utility model, each rotating shaft 5 includes a first shaft 51 and a second shaft 52 with overlapping axes. The first shaft 51 and the second shaft 52 are connected by a power adjustment member 7. The power adjustment member 7 is driven to move so that the motor 6 drives the first shaft 51 and the second shaft 52 to rotate synchronously or independently.

[0036] Furthermore, the power adjustment component 7 includes a transmission sleeve 71 and a drive unit. The transmission sleeve 71 is fitted onto the outside of the first shaft 51 and the second shaft 52. An internal gear 711 is provided inside the transmission sleeve 71. A first gear 53 is fixedly connected to one end of the transmission sleeve 71 corresponding to the first shaft 51 and the second shaft 52. The first gear 53 cooperates with the internal gear 711. The drive unit drives the transmission sleeve 71 to move axially along the first shaft 51.

[0037] Furthermore, the drive unit includes an electric push rod 72 installed in the fixed base 1. The electric push rod 72 is arranged parallel to the first shaft 51, and the output end of the electric push rod 72 is rotatably connected to the transmission sleeve 71 through a connector.

[0038] Preferably, the connector includes an adjusting ring 73 rotatably mounted on one end of the transmission sleeve 71, a connecting block 731 fixedly connected to the outer wall of the adjusting ring 73, and the output end of the electric push rod 72 fixedly connected to the connecting block 731.

[0039] Furthermore, both the left gate 31 and the right gate 32 are rotatably connected to the corresponding fixed base 1 via a rotating shaft 311. A first torsion spring 312 is fitted on the rotating shaft 311 of the left gate 31 and the right gate 32 corresponding to the first barrier 3. A second torsion spring 313 is fitted on the rotating shaft 311 of the left gate 31 and the right gate 32 corresponding to the second barrier 4. The first torsion spring 312 causes the left gate 31 and the right gate 32 of the first barrier 3 to have an opening tendency, and the second torsion spring 313 causes the left gate 31 and the right gate 32 of the second barrier 4 to have a closing tendency.

[0040] Specifically, in the above embodiments, the motor 6 drives each left gate 31 and right gate 32 respectively, which makes the control method relatively complex in actual use. In this embodiment, the rotating shaft 5 includes a first shaft 51 and a second shaft 52, such as... Figure 2 As shown, the first shaft 51 and the second shaft 52 are arranged on the same axis, and there is a certain gap between the first shaft 51 and the second shaft 52. The first shaft 51 in the two fixed seats 1 is respectively connected to the left gate plate 31 and the right gate plate 32 of the first barrier gate 3. Preferably, the first shaft 51 is connected to the rotating shaft 311 on the left gate plate 31 and the right gate plate 32 of the first barrier gate 3 through a bevel gear set 511. Similarly, the second shaft 52 is connected to the rotating shaft 311 on the left gate plate 31 and the right gate plate 32 of the second barrier gate 4 through a bevel gear set 511. That is, a total of four sets of bevel gear sets 511 are provided. The first shaft 51 and the second shaft 52 are fitted with a transmission sleeve 71 at opposite ends. An internal gear 711 is provided on the inner side of the transmission sleeve 71. Figure 2 As shown, an adjusting ring 73 is fitted onto one end of the transmission sleeve 71, and a connecting block 731 is fixedly connected to the outer wall of the adjusting ring 73. The output end of the electric push rod 72, which is located in the fixed base 1, is fixedly connected to the connecting block 731 so that when the electric push rod 72 extends or retracts, it can drive the transmission sleeve 71 to slide along the axial direction of the first shaft 51. The internal gear 711 in the transmission sleeve 71 meshes with the first gear 53 on the first shaft 51 and the second shaft 52 at the same time. At this time, when the transmission sleeve 71 is driven to rotate, it can drive the first shaft 51 and the second shaft 52 to rotate synchronously. Since the first shaft 51 and the second shaft 52 rotate synchronously and in the same direction, the rotation directions of the first barrier 3 and the second barrier 4 are opposite. In specific implementation, when the first barrier 3 is in the open state, the second barrier 4 is in the closed state, and vice versa.

[0041] Since the first torsion spring 312 tends to open the left gate 31 and right gate 32 of the first barrier gate 3, and the second torsion spring 313 tends to close the left gate 31 and right gate 32 of the second barrier gate 4, in actual use, the transmission sleeve 71 is moved to the outside of the second shaft 52 by the electric push rod 72. At this time, the first shaft 51 is not restricted by the transmission sleeve 71. The first torsion spring 312 tends to open the left gate 31 and right gate 32 of the first barrier gate 3. After the transmission sleeve 71 tends to open the left gate 31 and right gate 32 of the second barrier gate 4, the electric push rod 72 moves the transmission sleeve 71 to the first gear 53 on the first shaft 51 to mesh with the internal gear 711. At this time, the first barrier gate 3 and the second barrier gate 4 can be kept in the open state so that unauthorized personnel can pass through when there are visitors in the park.

[0042] Similarly, by moving the transmission sleeve 71 via the electric push rod 72, both the first barrier 3 and the second barrier 4 can be kept closed to accommodate special circumstances.

[0043] In the specific implementation process, the setting of the first torsion spring 312 and the second torsion spring 313 can ensure that the left gate 31 and the right gate 32 are in the open or closed state, so that the internal gear 711 of the transmission sleeve 71 can be aligned with the first gear 53 on the first shaft 51 and the second shaft 52, thereby preventing the transmission sleeve 71 from being blocked by the first gear 53 and unable to slide along the axial direction of the first shaft 51.

[0044] Optionally, the output shaft of the motor 6 is fixedly connected to the second gear 61, and the external gear 712 is provided on the outside of the transmission sleeve 71. During the stroke of the transmission sleeve 71 moving axially along the first shaft 51, the second gear 61 remains engaged with the external gear 712. In specific implementation, a micro reducer can be installed in the fixed base 1 to control the rotation speed of the left gate 31 and the right gate 32.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
