Description

Technical Field

[0001] The present invention relates to the technical field of intelligent security, and specifically to an intelligent security access control system. Background Art

[0002] An intelligent security access control system is a security system used to control and manage the entry and exit of personnel in a specific area. Through identity verification, permission management, and real-time monitoring, it ensures that only authorized personnel can enter, thereby effectively improving the security of the area. Its development process has evolved from early mechanical locks and keys to electronic password locks and card recognition systems, and now to face recognition. Modern security access control systems not only have efficient identity verification functions but also can be linked with monitoring, alarm, fire protection and other systems to form an integrated security system, which is widely used in places with high security requirements such as commercial office buildings, residential communities, public transportation hubs, financial institutions, and data centers. With the further development of artificial intelligence, cloud computing, and 5G technologies, the intelligent security access control system will evolve towards a more intelligent, integrated, and cloud-managed direction, supporting remote control, automated management, and big data analysis.

[0015] The present invention has the following beneficial effects: 1. For the intelligent security access control system, the power motor drives the gear to mesh with the rack, driving the sliding square column, the mounting block, the display and the camera to slide up and down as a whole, realizing the automatic adjustment of the camera height according to the height of the person, ensuring that the camera always aims at the face, improving the recognition accuracy and user experience, and meeting the needs of people with different heights; at the same time, the sliding groove provides enough sliding space for the power motor, preventing the device from getting stuck during the lifting process, and preventing the mounting block from separating from the side wall of the turnstile during the sliding process. Through such a design, the camera can operate stably during the up and down sliding process, minimizing the jitter situation and providing a stable support for the recognition of the camera.

[0016] 2. For the intelligent security access control system, when the power motor rotates, through the linkage of the core rod, the raised piece and the arc groove, the wire winding column is driven to rotate synchronously, realizing the automatic winding or releasing of the wire, avoiding the chaos of the wire inside the turnstile, optimizing the wire management, reducing the resistance when the camera slides up and down, preventing the camera from getting stuck or jittering, and ensuring the long-term stable operation of the device.

[0017] 3. In this intelligent security access control system, when the terminal block slides, the fixed ring pushes against the inclined surface, causing the first arc contact piece to separate from the terminal block and the second arc contact piece to contact the terminal block. This enables the first and second arc contact pieces to be used alternately. When the winding post is winding and unwinding the wire, it can rub against different arc contact pieces, reducing the friction on the same arc contact piece in this way. When the terminal block is in a static state, both the first and second arc contact pieces are in contact with the terminal block. When either the first or second arc contact piece separates from the terminal block, the other arc contact piece remains in contact with the terminal block, ensuring that the circuit remains conductive throughout the switching process, avoiding power outages or poor contacts. By reducing the wear of the arc contact pieces, the service life of the power connection components is extended, and the equipment maintenance and replacement costs are reduced. The switching process of the contact pieces is stable and reliable, ensuring the stable operation of the camera during the up-and-down sliding and wire-winding processes, and avoiding equipment failures caused by circuit problems.

Specific implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1, please refer to Figures 1-11 The present invention discloses an intelligent security access control system, including a turnstile 1. A sliding square column 13 is slidably connected to the upper side of the turnstile 1. A display 11 is installed at the upper end of the sliding square column 13. A camera 12 is arranged on the display 11. An installation block 14 is arranged at the lower end of the sliding square column 13. A friction plate 23 is arranged inside the installation block 14. A wire winding post 22 for winding an electric wire 4 is rotatably connected to the friction plate 23. Through the design of the friction plate 23, a certain force is required for the wire winding post 22 to rotate, so that the position of the wire winding post 22 can be stable. A terminal 28 is rotatably connected to the middle of the wire winding post 22. One end of the terminal 28 is square-shaped. See Figure 8, the terminal 28 is of a two-piece design. The left end of the terminal 28 is slidably connected to the mounting block 14. Through this design, it can prevent the terminal 28 from rotating together when the wire 4 is wound or released, thereby causing torsional damage to the wire 4. One end of the winding post 22 is slidably connected with a plurality of first arc-shaped pieces 31. A first sliding block 37 is fixedly connected below the first arc-shaped piece 31. A first tension spring 38 is fixedly connected to one side of the first sliding block 37. The other end of the first tension spring 38 is fixedly connected to the inside of the winding post 22. A connecting rod 32 is fixedly connected to one side of the first arc-shaped piece 31. The other end of the connecting rod 32 is fixedly connected to a first arc-shaped contact piece 33. The first arc-shaped contact piece 33 contacts the cylindrical part of the terminal 28. Through the design of the first tension spring 38, it can pull the first sliding block 37 and the first arc-shaped piece 31 to slide, so that the first arc-shaped piece 31 can pull the connecting rod 32 and the first arc-shaped contact piece 33 to slide together, so that the first arc-shaped contact piece 33 can always contact the cylindrical part of the terminal 28. It should be noted that see Figure 5 , the friction plate 23 is used to limit the winding post 22.

[0033] A chute 18 is provided inside the turnstile 1. The power motor 2 is slidably connected to the chute 18. A fixing block 15 is fixedly connected to one side of the mounting block 14. A lead screw 16 is threadedly connected to the fixing block 15. The lower end of the lead screw 16 is fixedly connected to a drive motor 17. The drive motor 17 is installed inside the turnstile 1.

[0034] It should be noted that the mounting block 14 is slidably connected to one side inside the turnstile 1, and at the same time, the mounting block 14 will not separate from the side wall of the turnstile 1. Through this design, when the mounting block 14 slides up and down, the situation of sliding position deviation will not occur, so that the mounting block 14 can slide up and down stably inside the turnstile 1.

[0035] When a person wants to enter the access control, the height of the display 11 will be automatically adjusted according to the person's height. The drive motor 17 drives the lead screw 16 to rotate. When the lead screw 16 rotates, under the action of the fixing block 15, the fixing block 15 will drive the mounting block 14, the sliding square column 13, the display 11 and the camera 12 to slide up and down together. Through the cooperation between the fixing block 15 and the lead screw 16, when driving the mounting block 14 and the sliding square column 13 to slide up and down, the power motor 2 slides inside the chute 18. Through the design of the chute 18, enough space can be vacated for the power motor 2 to slide to prevent jamming. Through the up and down sliding of the sliding square column 13, the display 11 can drive the camera 12 to slide up and down together, so that the camera 12 can identify the face of the person.

[0036] In this embodiment: Through the sliding square column 13 and the mounting block 14 slidably connected inside the turnstile 1, and through the cooperation between the drive motor 17 on the mounting block 14, the fixed block 15 and the lead screw 16, the sliding square column 13, the mounting block 14, the display 11 and the camera 12 are driven to slide up and down, so as to control the positions of the display 11 and the camera 12, enabling the camera 12 to recognize the faces of people. At the same time, through the design of the sliding square column 13 and the mounting block 14, when the display 11 and the camera 12 slide up and down, they can be more stable, preventing jitter during the up and down sliding of the display 11 and the camera 12.

[0037] Embodiment 2. This embodiment aims to facilitate the solution of the problem that the wires 4 inside the turnstile 1 may be wound around each other during the up and down sliding of the camera 12, resulting in chaos of the internal wires 4. This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1-11 , a power motor 2 is provided on one side of the mounting block 14. The power output end of the power motor 2 is fixedly connected to a core rod 24. The core rod 24 is located inside the winding column 22, and the core rod 24 is rotatably connected to the winding column 22.

[0038] An arc-shaped groove 21 is opened inside the winding column 22. Second springs 312 are provided on both sides of the arc-shaped groove 21. A protruding column 3 is provided on one side of the arc-shaped groove 21. The arc-shaped groove 21 is located inside the winding column 22.

[0039] A protruding piece 25 is fixedly connected to one side of the core rod 24. The protruding piece 25 is slidably connected to the arc-shaped groove 21. Through the design of the arc-shaped groove 21 and the protruding piece 25, when the core rod 24 rotates, it first drives the right ends of the square rod 27 and the wiring column 28 to rotate. The two sides of the protruding piece 25 are in contact with the second springs 312. The two sides of the protruding piece 25 are in contact with the second springs 312. Through the design of the second springs 312, power can be provided for the reset of the protruding piece 25, enabling the protruding piece 25 to be in the middle position of the arc-shaped groove 21.

[0040] A square groove 26 is opened inside the core rod 24. A square rod 27 is slidably connected to the square groove 26. The other end of the square rod 27 is fixedly connected to one end of the wiring column 28. A spiral groove 29 is opened on the cylinder of the wiring column 28. The protruding column 3 is slidably connected to the spiral groove 29. It should be noted that the square rod 27 is fixedly connected to the right end of the wiring column 28, and the spiral groove 29 is also opened on the right end of the wiring column 28. At the same time, during the subsequent rotation of the wiring column 28, the left end of the wiring column 28 will not rotate under the action of the mounting block 14, only the right end of the wiring column 28 rotates.

[0041] During the up and down sliding of the sliding square column 13 and the mounting block 14, the power motor 2 will start, driving the core rod 24 to rotate. While the core rod 24 rotates, it also drives the protruding piece 25 to rotate together. At this time, the winding column 22 is restricted by the friction of the friction plate 23, so that the winding column 22 will not rotate with the core rod 24 and the protruding piece 25. At this time, the rotation of the protruding piece 25 will resist the second spring 312 on one side, and the protruding piece 25 will slide in the arc groove 21. When the protruding piece 25 slides to the end of the arc groove 21, as the core rod 24 continues to drive the rotation of the protruding piece 25, the protruding piece 25 will drive the winding column 22 to rotate together. Through the rotation of the winding column 22, the wire 4 can be wound around the winding column 22, or the wire 4 on the winding column 22 can be released, so that when the sliding square column 13, the mounting block 14, the display 11 and the camera 12 slide up and down, there will be no confusion of the wire 4 inside.

[0042] In the present embodiment: the power motor 2 drives the core rod 24 and the protruding piece 25 to drive the winding column 22 to rotate together, and the wire 4 is wound or released through the rotation of the winding column 22. Through such a design, it is possible to effectively prevent the wires 4 inside the gate machine 1 from being entangled with each other during the process of driving the camera 12 to slide up and down by the sliding square column 13 and the mounting block 14, causing the camera 12 to be stuck, and further enable the camera 12 to operate stably during subsequent use.

[0043] Embodiment 3: This embodiment is intended to promote the solution. In the process of winding the wire 4 by the winding post 22, the terminal 28 and the first arc contacting piece 33 are greatly worn, which may cause poor contact during the later use. This embodiment is an improvement made on the basis of Embodiment 1 and Embodiment 2. For details, please refer to Figures 1-11 A second arc-shaped piece 35 is provided on one side of the first arc-shaped piece 31, and a second sliding block 39 is fixedly connected to the lower side of the second arc-shaped piece 35. The second sliding block 39 is slidably connected to the winding post 22, and a second tension spring 310 is fixedly connected to the lower side of the second sliding block 39. The other end of the second tension spring 310 is provided in the winding post 22.

[0044] A control rod 36 is fixedly connected to one side of the second arc-shaped piece 35, and one end of the control rod 36 is fixedly connected to a second arc connecting piece 311. The second arc connecting piece 311 is used to contact the cylindrical part of the terminal 28. Through the design of the second tension spring 310, the second sliding block 39 can pull the second arc-shaped piece 35, the control rod 36 and the second arc connecting piece 311 to slide inward, so that the second arc connecting piece 311 can always be in contact with the cylindrical part of the terminal 28.

[0045] A resisting inclined surface 34 is formed on one side of the first arc contacting piece 33 and the second arc contacting piece 311 .

[0046] It should be noted that, through the design of the friction plate 23, when the power motor 2 starts to drive the core rod 24 to rotate, the friction plate 23 restricts the winding post 22 from winding or releasing the wire 4, and the first arc connecting piece 33 and the second arc connecting piece 311 will not rub against the cylindrical part of the terminal 28. When the core rod 24 drives the protruding piece 25 to rotate toward one end of the arc groove 21, the square rod 27 drives the terminal 28 and the spiral groove 29 on the terminal 28 to rotate together, so that the spiral groove 29 cooperates with the protruding column 3. Through such cooperation, the terminal 28 can be connected to the spiral groove 29 of the spiral groove 29. The column 28 slides, and the sliding of the terminal 28 drives the fixed ring 210 to slide together, thereby abutting against the abutting inclined surface 34 of the first arc connecting piece 33 or the second arc connecting piece 311, so that the arc connecting piece on one side is separated from the terminal 28, and then the protruding piece 25 will abut against one end of the arc groove 21, thereby driving the winding column 22 to rotate together. Through such a design, the wire 4 will not be wound up or released until an arc connecting piece is separated from the terminal 28, which can reduce the wear between an arc connecting piece and the terminal 28 during the winding or releasing process of the wire 4.

[0047] A fixed ring 210 is fixedly connected to the cylindrical part of the terminal 28, and the fixed ring 210 is used to interfere with the inclined surface of the interference slope 34. Through the design of the fixed ring 210 interfering with the inclined surface of the interference slope 34, the fixed ring 210 will interfere with the interference slope 34 while moving, so that the first arc connecting plate 33 or the second arc connecting plate 311 will expand outward.

[0048] It should be noted that the terminal 28, the first arc-shaped piece 31, the connecting rod 32, the first arc-connecting piece 33, the second arc-shaped piece 35, the control rod 36, and the second arc-connecting piece 311 are all made of conductive metal materials. Through such a design, the circuit can be normally conducted; During the process of the core rod 24 driving the convex piece 25 to rotate, it will drive the terminal 28 at the right end to rotate together through the square rod 27. While the terminal 28 rotates, it will drive the spiral groove 29 on the terminal 28 to slide with the convex column 3. Through the cooperation of the convex column 3 and the spiral groove 29, the terminal 28 can slide left and right, causing the square rod 27 to slide into the square groove 26; while the terminal 28 slides left and right, it will drive the fixed ring 210 to slide together. While the fixed ring 210 slides, one side of the fixed ring 210 will be in contact with the inclined surface of the abutting inclined surface 34. As the fixed ring 210 abuts against the abutting inclined surface 34, the abutting inclined surface 34 can drive the first arc contact piece 33 or the second arc contact piece 311 to expand outward, causing the first arc contact piece 33 or the second arc contact piece 311 to move away from the terminal 28, so that only one arc contact piece is in contact with the terminal 28. Thus, during the subsequent process of winding or unwinding the wire 4, only one arc contact piece is rubbed; see Figure 9 , when the terminal 28 drives the fixed ring 210 to slide to the left, the fixed ring 210 will abut against the abutting inclined surface 34 on the first arc contact piece 33. While the first arc contact piece 33 expands and slides upward, it will drive the first arc-shaped piece 31 and the connecting rod 32 to slide upward together, causing the first tension spring 38 to deform. At the same time, the first arc contact piece 33 will no longer be in contact with the terminal 28. During the process of winding the wire 4, through the design of automatically separating the first arc contact piece 33 from the terminal 28, the wear between the first arc contact piece 33 and the terminal 28 is reduced; similarly, when the terminal 28 drives the fixed ring 210 to slide to the right, the fixed ring 210 will abut against the abutting inclined surface 34 on the second arc contact piece 311. While the second arc contact piece 311 expands and slides upward, it will drive the second arc-shaped piece 35 and the control rod 36 to slide upward together, causing the second tension spring 310 to deform. At the same time, the second arc contact piece 311 will no longer be in contact with the terminal 28. During the process of winding the wire 4, through the design of automatically separating the second arc contact piece 311 from the terminal 28, the wear between the second arc contact piece 311 and the terminal 28 is reduced.

[0049] It should be noted that the initial position of the protruding column 3 is in the middle section of the spiral groove 29. When the wire 4 is wound or released, it will rotate, so that the sliding direction of the fixed ring 210 is controlled by the cooperation between the protruding column 3 and the spiral groove 29. At the same time, when the mounting block 14 drives the sliding square column 13, the display 11 and the camera 12 to slide to the appropriate position, the power motor 2 will stop rotating. At the same time, the protruding piece 25 will slide to the middle of the arc groove 21 under the action of the second spring 312. While sliding, the protruding piece 25 will drive the core rod 24 The rotation will also cause the spiral groove 29 to cooperate with the raised column 3, allowing the raised column 3 to slide back to the middle section of the spiral groove 29, so that the fixed ring 210 can return to the position between the first arc connecting piece 33 and the second arc connecting piece 311, so that the first arc connecting piece 33 and the second arc connecting piece 311 can both contact with the cylindrical part of the terminal 28, so that after the wire 4 is wound or released, the first arc connecting piece 33 and the second arc connecting piece 311 will contact with the terminal 28 at the same time, which can effectively prevent wear between the terminal 28 and the arc connecting piece.

[0050] In this embodiment: through the sliding of the terminal 28, the fixed ring 210 is in contact with the inclined surface of the contact inclined surface 34, so that the contact inclined surface 34 drives the arc connecting piece to separate from the terminal 28, so that when the subsequent winding post 22 winds the wire 4, the wear between one arc connecting piece and the terminal 28 is reduced, thereby increasing the service life of the equipment to a certain extent, and further enabling the camera 12 to operate stably during subsequent use. It should be noted that when the power motor 2 just drives the core rod 24, the protruding piece 25 and the square rod 27 to rotate, the protruding piece 25 first rotates in the arc groove 21, so that one group of arc connecting pieces is separated from the terminal 28 first, and the protruding piece 25 will rotate to one end of the arc groove 21, thereby driving the winding post 22 to rotate. Through such a design, when one group of arc connecting pieces does not conflict with the terminal 28, it starts to wind or release the wire 4, which can reduce the wear between a group of arc connecting pieces and the terminal 28.

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0052] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
