AI Technical Summary
Existing facial recognition access control and attendance systems cannot handle multi-directional personnel flow simultaneously, resulting in blind spots or the need to install multiple devices, increasing costs and space occupation. Furthermore, they are slow to recognize people when they are in dense crowds, leading to long queuing times.
Using two sets of cameras (telephoto and short-focus cameras) in conjunction with a control and switching unit, it can simultaneously perform facial recognition on the same side of the person. It uses a laser to divide the recognition range, first performing a large-scale recognition, and then skipping high-precision recognition if successful. Those who fail are then subjected to high-precision recognition. The control and switching unit can also be used to rotate and clean the cameras.
It improves attendance recognition efficiency, shortens recognition time, reduces equipment costs, enhances cleaning effectiveness, and strengthens the system's flexibility and applicability.

Abstract
Description
Background Technology
[0001] Facial recognition access control and attendance systems are intelligent management systems integrating advanced biometric technology. Their primary purpose is to achieve precise control over personnel entering and exiting specific areas and automated attendance recording. Users no longer need to carry keys, access cards, or remember passwords; they can simply "scan their face" for seamless access and clocking in / out, greatly improving convenience and efficiency. Its far-reaching significance lies in its ability to significantly enhance area security through unique and difficult-to-forge biometric features, effectively preventing tailgating and identity theft. Simultaneously, automated attendance eliminates human fraud such as proxy clocking, making management data more objective and fair, saving management costs for enterprises, and promoting the digital and intelligent transformation and upgrading of management. It is one of the core tools for building a safe, efficient, and modern office and living environment.
[0002] Current attendance systems typically use a single camera mounted on a single recognition device, fixed in one direction, making it unable to handle multi-directional movement of people simultaneously. This means that in scenarios requiring simultaneous monitoring of people on both sides, conventional devices may not provide effective coverage, resulting in blind spots or necessitating the installation of multiple devices, increasing cost and space requirements. Furthermore, conventional attendance systems employ a single recognition mode, requiring all personnel to undergo the same high-precision recognition process without any tiered processing mechanism. This leads to slow recognition speeds and long queue times during peak attendance periods, as each person must complete the entire recognition process. Summary of the Invention
[0003] The present invention aims to at least partially solve one of the technical problems in the related art.
[0004] Therefore, the purpose of this invention is to provide a facial recognition access control and attendance system. This invention can simultaneously recognize the faces of people on the same side, and can also rotate to both sides to detect people moving in different directions on both sides. This makes it applicable to different application scenarios, more flexible, and can effectively improve the efficiency of attendance recognition, shortening the time required for attendance recognition of a large number of people.

[0011] Furthermore, the arc-shaped plate is used to lift the protruding post and the rotating disk upwards, and a magnetic block is embedded in the bottom of the groove, and the groove uses the internal magnetic block to attract and adhere the ball part. There are two connecting posts, and each connecting post extends downward from the bottom of the transmission box. The rotating disk drives the drive gear to rotate by embedding the bottom ball into the groove.
[0012] Furthermore, the fencing assembly includes: The enclosure, concealed groove, and cleaning components are provided.

The end of the lifting rod is a horizontal straight structure and is embedded in the notch on the side of the power compartment. The lifting rod is used to press against the surface of the rotating disk. After the rotating disk is raised and lowered, it drives the cleaning component to move up and down synchronously inside the hidden slot.
[0015] The technical solution provided by this invention may include the following beneficial effects: 1. This facial recognition access control and attendance system is equipped with two sets of recognition cameras, namely a telephoto camera and a short-focus camera. The two cameras, together with the top control and switching unit, can simultaneously perform facial recognition on the same side of the person, or they can be rotated to the two sides to detect people moving in different directions on both sides at the same time, so that they can be applied to different application scenarios and have greater flexibility.
[0016] 2. When performing facial recognition on the same side of the face, this facial recognition access control and attendance system divides the recognition range in the recognition unit using a laser. It first uses a short-focus camera to simultaneously recognize a large number of people. If the recognition is successful, subsequent high-precision long-focus recognition is not required. Only those people who have not been recognized by the short-focus camera are allowed to enter the recognition area of the long-focus camera for subsequent targeted high-precision recognition. This effectively improves the efficiency of attendance recognition and shortens the time required for attendance recognition of a large number of people.
[0017] 3. This facial recognition access control and attendance system, through the control and switching unit and the rubbing wheel, can control both cameras to dock with the enclosure component. After docking, it can simultaneously provide shielding protection for each camera and, together with the cleaning component, achieve the cleaning process of the lens. This process can also be achieved with the help of a single power device in the control and switching unit, which improves the utilization rate of the power device, reduces equipment costs, and improves the cleaning effect.

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0021] like Figures 1 to 8As shown, this embodiment of the invention proposes a face recognition access control and attendance system, including: a calculation unit, a control and switching unit 8, an access control unit and an identification unit 7. The calculation unit includes a personnel information management module, a face recognition algorithm engine, an attendance management module and a system management backend. The system management backend is equipped with an access controller. The identification unit 7 includes a telephoto camera 13 and a short-focus camera 14. The outer side of the identification unit 7 is equipped with a frame, which includes a back plate 1, a top plate 2 and a bottom plate 3, and the back plate 1, top plate 2 and bottom plate 3 are integrally formed. A barrier assembly 6 is provided on the back plate 1. The bottom of the identification unit 7 is embedded in the surface of the bottom plate 3. A display screen 5 is screwed to the top of the top plate 2. The display screen 5 is used to display the information of the person who has completed the identification. The top of the identification unit 7 is equipped with a control switching unit 8, and the top of the control switching unit 8 is equipped with a rubbing wheel 18. The rubbing wheel 18 is used to control the rotation of the entire control switching unit 8 and the identification unit 7. The enclosure component 6 is used to cover and protect the ends of the telephoto camera 13 and the short-focus camera 14. The inner side of the enclosure component 6 is embedded with a cleaning component 21, which is used to wipe and clean the lens parts of the telephoto camera 13 and the short-focus camera 14.
[0022] During installation, this facial recognition access control and attendance system is mounted on a wall or pillar using fixing plates 4 at the top and bottom of the frame. It utilizes two sets of side cameras: a telephoto camera 13 and a short-focus camera 14, to perform facial recognition on passing personnel. The recognized personnel information is directly displayed on the top display screen 5. A control and switching unit 8 is located at the top of the recognition unit 7, allowing direct adjustment of the positions of the telephoto camera 13 and the short-focus camera 14. This allows the cameras to be positioned at an angle or extended to their maximum parallel state. This enables simultaneous recognition of personnel on the same side or from different directions.
[0023] After the telephoto camera 13 and the short-focus camera 14 are fully aligned and parallel by the control switching unit 8, the entire recognition unit 7 can be rotated by rotating the top rubbing wheel 18, thereby embedding the ends of the telephoto camera 13 and the short-focus camera 14 into the inner side of the enclosure component 6 to provide shielding protection. In this state, when the motor 27 is started again, the up and down movement of the internal rotating disk 32, together with the cleaning component 21, can achieve the purpose of cleaning the lens parts of the telephoto camera 13 and the short-focus camera 14.
[0024] In this embodiment, the identification unit 7 further includes: The rotating column 9, the support bearing 10, the transmission box 11 and the power chamber 16 are provided. The bottom of the rotating column 9 is fitted with the support bearing 10. The bottom of the support bearing 10 is embedded in the bottom plate 3. The sides of the telephoto camera 13 and the short-focus camera 14 are fitted with protrusions 15. After the two protrusions 15 are in contact with each other, the telephoto camera 13 and the short-focus camera 14 remain parallel to each other. A transmission box 11 is installed on the top of the rotating column 9, and a power chamber 16 is screwed to the top of the transmission box 11. The control and switching unit 8 is installed inside the power chamber 16 and the transmission box 11. A notch 28 is provided on one side of the bottom of the power chamber 16.
[0025] The identification unit 7 also includes an extension plate 26, a central shaft 17, and a rubbing wheel 18. The extension plate 26 is integrally formed on the side of the power compartment 16. The central shaft 17 is inserted into the top of the extension plate 26. The rubbing wheel 18 is installed at the top of the central shaft 17, and the central shaft 17 extends upward from the inside of the top plate 2. A laser 12 is installed on the side of the transmission box 11. The telephoto camera 13 and the short-focus camera 14 are symmetrically arranged on both sides of the laser 12. The laser 12 emits a beam of light that illuminates the ground area below the middle of the telephoto camera 13 and the short-focus camera 14, in order to delineate the recognition area corresponding to the telephoto camera 13 and the short-focus camera 14.
[0026] Equipped with two sets of recognition cameras, namely a telephoto camera 13 and a short-focus camera 14, the two cameras, together with the top control and switching unit 8, can simultaneously perform facial recognition on people on the same side, or can be rotated to both sides to detect people moving in different directions on both sides at the same time, thus making it suitable for different application scenarios and more flexible.
[0027] Specifically, in the recognition unit 7, the telephoto camera 13 and the short-focus camera 14 can perform facial recognition on images of a large or small area, respectively. Therefore, when the two telephoto cameras 13 and the short-focus camera 14 are controlled to face the same side for recognition by the control switching unit 8, and there is a certain angle between the telephoto camera 13 and the short-focus camera 14 (i.e., Figure 2 (As shown in the diagram), when a person moves past the short-focus camera 14, multiple people are simultaneously visible in the image frame of the short-focus camera, enabling large-scale facial recognition. The recognized individuals are then displayed on the screen 5, thus bypassing the recognition process of the long-focus camera 13. The long-focus camera 13 then performs targeted, one-by-one recognition on those individuals not successfully identified by the short-focus camera 14, until all individuals have been identified.
[0028] This embodiment also provides a recognition process in which the telephoto camera 13 and the short-focus camera 14 are directed toward different directions on both sides, as follows: By controlling the switching unit 8 to point the telephoto camera 13 and the short-focus camera 14 to different directions, the people on both sides can be identified one by one through the telephoto camera 13 and the short-focus camera 14, thus completing the recognition task on the dual-channel path.
[0029] In this embodiment, the control switching unit 8 includes: The motor 27, drive shaft 29, fixed ring 30, second spring 31, rotating disk 32, and lifting sleeve 33 are provided. The motor 27 is screwed to the top of the power compartment 16. The output end of the motor 27 is connected to the drive shaft 29. The fixed ring 30 is welded to the surface of the drive shaft 29. The second spring 31 is welded to the bottom of the fixed ring 30. The lifting sleeve 33 is provided at the bottom end of the second spring 31. The rotating disk 32 is integrally formed at the bottom of the lifting sleeve 33. The inner side of the lifting sleeve 33 is provided with a flat key, and the surface of the drive shaft 29 is provided with a lifting groove. The lifting sleeve 33 is embedded into the lifting groove through the flat key. The motor 27 drives the rotating disk 32 to rotate through the drive shaft 29 and the flat key. The rotating disk 32 moves up and down along the lifting groove on the drive shaft 29 through the flat key on the inner side of the lifting sleeve.
[0030] The control switching unit 8 further includes: The drive gear, driven gear 39, arc plate 37, groove 38 and connecting column 40 are provided. The bottom of the drive gear and driven gear 39 are both equipped with connecting column 40. The bottom of the connecting column 40 is integrally formed with the rotating column 9. The drive gear and driven gear 39 mesh with each other. The surface of the drive gear is provided with groove 38, and the surface of the drive gear is also welded with arc plate 37. The number of grooves 38 and arc plates 37 are both two, and the driving gear and driven gear 39 are used to control the telephoto camera 13 and the short-focus camera 14 at the bottom to rotate in opposite directions.
[0031] The control and switching unit 8 also includes a protrusion 34 and a ball 35. The protrusion 34 is welded to the bottom of the rotating disk 32. Each protrusion 34 has a ball 35 embedded at its bottom end. The protrusion 34 is pressed against the surface of the drive gear by the ball 35 at its bottom. The ball 35 is also used to be embedded in the inside of the groove 38 or to roll along the surface of the arc plate 37.
[0032] The arc plate 37 is used to push the protruding post 34 and the rotating disk 32 upward. The bottom of the groove 38 is fitted with a magnetic block, and the groove 38 uses the internal magnetic block to attract and adhere the ball 35 part. There are two connecting posts 40, and each connecting post 40 extends downward from the bottom of the transmission box 11. The rotating disk 32 drives the drive gear to rotate by embedding the bottom ball bearing 35 into the groove 38.
[0033] When performing facial recognition, the recognition unit 7 uses a laser 12 to divide the recognition range, and first uses a short-focus camera 14 to simultaneously recognize a large number of people. If the recognition is successful, there is no need to perform subsequent long-focus high-precision recognition. Only those people who have not been recognized by the short-focus camera 14 enter the recognition area of the long-focus camera 13 for subsequent targeted high-precision recognition. This can effectively improve the efficiency of attendance recognition and shorten the time required for attendance recognition of a large number of people.
[0034] Specifically, after starting the motor 27, the motor 27 drives the drive shaft 29 to rotate. The drive shaft 29, through the lifting groove on its surface and the flat key inside the lifting sleeve 33, can directly drive the rotating disk 32 at the bottom to rotate. The rotating disk 32 is embedded in the groove 38 of the drive gear through the protrusion 34 and the ball 35 at the bottom. At this time, the drive gear can be controlled to rotate by means of the interlocking effect between the groove 38 and the ball 35 and the magnetic attraction structure inside the groove 38. In turn, the driven gear 39 and the corresponding telephoto camera 13 and short-focus camera 14 at the bottom are rotated to achieve the purpose of adjusting the angle between the telephoto camera 13 and the short-focus camera 14.
[0035] When the protrusion 15 between the telephoto camera 13 and the short-focus camera 14 is in contact, the two telephoto cameras 13 and the short-focus camera 14 block each other. Relying on the magnetic attraction effect of the ball 35, the groove 38 and the inside, they cannot continue to drive the drive gear to rotate. Therefore, the ball 35 will disengage from the inside of the groove 38. Subsequently, the motor 27 can only drive the ball 35 to rotate along the surface of the drive gear and press it over the groove 38 and the arc plate 37 in sequence, so that the rotating disk 32 can move up and down in this process.
[0036] In this embodiment, the fencing component 6 includes: The enclosure 19, the hidden groove 20, and the cleaning assembly 21 are provided. The top of the top plate 2 and the bottom of the bottom plate 3 are both welded with fixing plates 4. Threaded holes are opened on the surface of the fixing plates 4. The identification unit 7 is installed on the wall by passing screws through the threaded holes on the fixing plates 4. The enclosure 19 has an overall arc-shaped structure, and a hidden groove 20 is provided on the inner side of the enclosure 19. A cleaning component 21 is embedded inside the hidden groove 20. The telephoto camera 13 and the short-focus camera 14 both embed their lenses into the hidden groove 20 after rotating.
[0037] The cleaning component 21 includes: The sponge pad 22, the upright 23, the first spring 24 and the lifting rod 25 are provided. The upright 23 is inserted into the top of the sponge pad 22, the lifting rod 25 is provided at the top of the upright 23, and the first spring 24 is fixed at the top of the lifting rod 25. There are two of the first spring 24 and the upright 23. The sponge pad is in an arc shape. The sponge pad 22 is embedded inside the hidden groove 20, and the back of the sponge pad 22 is in contact with the inner wall of the hidden groove 20. The end of the sponge pad 22 is flush with the end of the surrounding plate 19.
[0038] The upright rod passes upward through the inside of the top of the enclosure 19 of the hidden groove 20, the first spring 24 is entirely embedded in the internal cavity of the enclosure 19, and the top of the second spring 31 is fixed in the internal area of the enclosure 19. The end of the lifting rod is a horizontal straight structure, and the end of the lifting rod is embedded in the notch 28 on the side of the power compartment 16. The lifting rod is used to press on the surface of the rotating disk 32. After the rotating disk 32 is raised and lowered, it drives the cleaning component 21 to move synchronously up and down inside the hidden groove 20.
[0039] By adjusting the switching unit 8 in conjunction with the scrubbing wheel 18, both cameras can be controlled to dock with the enclosure component 6. After docking, each camera can be protected by shielding. The cleaning component 21 can then be used to clean the lens. This process can be achieved using a single power device in the switching unit 8, which improves the utilization rate of the power device, reduces equipment costs, and improves the cleaning effect.
[0040] Specifically, when the rotating disk 32 is controlled by the motor 27 to move up and down, and the telephoto camera 13 and the short-focus camera 14 are rotated by the top scrubbing wheel 18 to be embedded in the hidden groove 20, the end of the lifting rod 25 will contact the top of the rotating disk 32 under the action of the second spring 31. Therefore, the moving up and down of the rotating disk 32 will also drive the lifting rod 25 to move up and down synchronously, thereby driving the sponge pad 22 at the bottom to move up and down, so as to achieve the effect of cleaning the lenses on the telephoto camera 13 and the short-focus camera 14.
