Description

Technical Field

[0001] This invention relates to the field of smart campus technology, specifically to an anti-interference facial recognition access control device for smart campuses. Background Technology

[0002] Most university campuses nowadays are equipped with facial recognition access control systems to restrict access for personnel. Facial recognition access control is a biometric technology that identifies individuals based on their facial features. It can, to a certain extent, ensure the free access of authorized personnel while restricting the entry of unauthorized personnel, thereby further improving the security of personnel within the campus. However, existing facial recognition devices still have some shortcomings and deficiencies that need to be improved: For example, a facial recognition access control system with application number CN202011265070.1 includes an access control main unit and an access control sub-unit. The main unit is located to one side of the sub-unit. A first light holder is fixedly installed on the front surface of the main unit, and a first warning light is fixedly installed on the inner side of the first light holder. A top cover is fixedly installed on the upper surface of the main unit. A front card reader is fixedly installed on the front surface of the top cover, and a rear card reader is fixedly installed on the rear surface of the top cover. A rotating support rod is movably installed on the upper surface of the top cover. A connecting shaft is movably connected to the upper outer surface of the rotating support rod. The front surface of the connecting shaft is movably connected to the connecting shaft. The access control unit is connected to an identification box. A display screen is fixedly installed on the front surface of the identification box. A fingerprint reader is fixedly installed on the front surface of the identification box below the display screen. A password button is movably installed on the front surface of the identification box below the fingerprint reader. A face scanning camera is movably installed on the upper surface of the identification box. A control button is movably installed on the rear surface of the access control unit. An emergency button is movably installed on the rear surface of the access control unit to one side of the control button. A right-side baffle is movably installed on one outer surface of the access control unit. Two anti-collision telescopic bars are movably installed on the outer surface of one outer surface of the access control unit in front of the right-side baffle.

[0003] The facial recognition devices mentioned in the above documents are mostly integrated and fixedly placed at the required work location. When the facial recognition device is damaged and needs to be replaced, the disassembly of the device is relatively cumbersome, which has certain drawbacks. At the same time, most facial recognition devices are placed outdoors, and the device itself may accumulate some dust. When the dust enters the inside of the device, it may affect the internal components and even cause damage to the components.

[0004] For example, a facial recognition access control system with application number CN202222908462.6 includes a base plate. A bracket is fixedly connected to the upper surface of the bottom of the base plate. A housing is fixedly connected to the end of the bracket away from the base plate. A fixing mechanism is slidably connected to any side wall of the housing. The fixing mechanism includes a fixed door panel. A rotating rod is rotatably connected to the center of the fixed door panel. A rotating block is fixedly connected to one end of the rotating rod inside the housing. Two push rods are sequentially fixedly connected to the outer wall of the rotating block. Sliding beads are embedded in the ends of the two push rods away from the rotating block. Moving plates are slidably connected to the ends of the two sliding beads away from the push rods. A limiting rod is fixedly connected to the end of the movable plate away from the sliding ball. Through the above technical solution, the fixing mechanism is designed to simultaneously fix the fixed door panel of the enclosure and the movable door panel of the support rod. This simple operation allows for simultaneous fixing of both door panels, improving disassembly and installation efficiency, and also enhancing maintenance efficiency. The limiting rod forms the fixing mechanism, which, through the rotation of the rotating block, drives the fixing mechanism on the fixed door panel to operate, thereby fixing the fixed door panel and the movable door panel to the enclosure and support rod respectively. This simple operation improves installation and fixing efficiency, which in turn enhances maintenance efficiency.

[0005] The facial recognition devices mentioned in the above documents mostly have exposed recognition panels. When the device is subjected to external impact, the panel may be damaged, affecting subsequent recognition work. At the same time, when existing recognition agencies recognize a person's face, they may also detect the face of a person behind them at the same time, which may lead to inaccurate recognition, missing scans, or false scans.

[0006] Therefore, we proposed an anti-interference facial recognition access control device for smart campuses to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide an anti-interference facial recognition access control device for smart campuses, in order to solve the problems mentioned in the background art. Currently, when facial recognition devices on the market are damaged and need to be replaced, the disassembly of the device is cumbersome. When dust enters the inside of the device, it may affect the internal components and even cause damage to the components. In addition, the recognition panel is mostly exposed. When the device is subjected to external impact, the panel may be damaged, and the recognition may be inaccurate, resulting in missed scans and false scans.

The main working column is fixedly connected to a first telescopic rod, and the output end of the first telescopic rod is fixedly connected to an identification panel. The identification panel is nested inside the main working column. The main working column is fixedly connected to a cleaning brush, and the outer end of the cleaning brush is attached to the front side of the identification panel.

[0010] Preferably, the main working column has horizontal slots on both the left and right sides, and a vertical slot is provided on the upper side of the horizontal slots, and a locking block is nested inside the vertical slot. The bottom of the placement slot is fixedly connected to a limiting groove, and a limiting plate is nested inside the limiting groove. An inclined plate is fixedly connected to the upper side of the limiting plate. The inclined plate is internally threaded with a threaded rod, and the outer end of the threaded rod is nested and connected to the right side of the placement platform, and a motor is fixedly connected to the outer end of the threaded rod. The upper side of the inclined plate is provided with a groove, and the inner front of the groove is connected to a limiting ball, and the upper end of the limiting ball is fixedly connected to the bottom end of the main working column.

[0011] Preferably, the limiting plate and the inclined plate are an integrated structure, and the inclined plate forms a sliding structure through a threaded rod, and the inclined plate drives the main working column to form a sliding structure through limiting balls.

[0012] Preferably, the horizontal and vertical slots are interconnected and are symmetrically distributed about the center point of the main working column.

[0013] Preferably, an auxiliary plate is fixedly connected to the output end of the second telescopic rod, and rotating rods are hinged to the left and right sides of the auxiliary plate, and a driving plate is hinged to the other end of the rotating rods; The lower end of the detection head is fixedly connected to a limiting rod, the lower end of the driving plate is fixedly connected to an adjusting plate, and the lower end of the adjusting plate is fixedly connected to a connecting rod, with the bottom end of the connecting rod nested and connected to the outside of the limiting rod.

[0014] Preferably, the sides of the adjustment plate are arc-shaped, and the position of the adjustment plate corresponds to that of the detection element. The rotating rod drives the adjustment plate through the driving plate to form a sliding structure.

[0015] Preferably, an expansion air bladder is nested at the bottom of the water tank, and a baffle plate is fixedly connected to the inner side of the expansion air bladder, and an interface is provided on the inner side of the baffle plate. The main working column is nested with a rotating shaft at its rear, and a torsion spring is fixedly connected to the outer side of the rotating shaft. The other end of the torsion spring is fixedly connected to the outer side of the main working column. At the same time, striking plates are fixedly connected to the left and right sides of the rotating shaft, and a vibrating plate is fixedly connected to the outer rear end of the main working column. A conveying block is fixedly connected to the rear side of the main working column, and a conveying pipe is connected through the bottom end of the conveying block. A condenser pipe is connected through the inner side of the conveying pipe, and a drain pipe is connected through the bottom end of the condenser pipe. The drain pipe extends to the outer end of the main working column.

[0016] Preferably, the striking plate is positioned opposite to the drain outlet of the water tank, the rotating shaft forms a rotating structure with the main working column through the striking plate, and the condenser tube is connected through the interior of the main working column, and the condenser tube is U-shaped when viewed from the side.

[0017] Compared with the prior art, the beneficial effects of the present invention are: (1) The rangefinder will detect the distance to the person's position. When the person is standing in front of the device and identification is required, the rangefinder will activate the first telescopic rod when it detects a close distance. The first telescopic rod will move the identification panel upward, so that the identification panel extends out from the inside of the main working column to detect the person's face. At the same time, the supplementary light will provide supplementary lighting for the person, reducing the possibility of identification difficulties in dim environments. When identification is completed, the moving identification panel will synchronously drive the cleaning brush to rotate. The cleaning brush will clean the dust on the surface of the identification panel, reducing the possibility of dust residue affecting subsequent identification. (2) When installing the main working column, the user can engage with the locking block through the horizontal slots on both sides of the main working column until the main working column is placed inside the placement slot. The user can start the motor and drive the inclined plate to slide horizontally through the threaded rod. When the inclined plate moves to one side, the main working column will rise simultaneously through the limiting ball. At this time, the locking block will enter the vertical slot under the action of the main working column rising. The vertical slot and the locking block cooperate with each other, and under the limiting action of the side fixing plate, the stability of the main working column can be further improved. At the same time, it is convenient for the staff to quickly disassemble and repair the main working column later. (3) When there are many people behind the person being tested and the background is cluttered, the second telescopic rod starts to run and pushes the auxiliary plate to move synchronously. At this time, the two ends of the rotating rod rotate under the action of the auxiliary plate, and the adjustment plate moves by driving the plate. When the adjustment plate moves, it will block the detection element to a certain extent, so that the detection element only performs face recognition processing on the people who are closer, which reduces the possibility of cluttered people behind the detection to a certain extent. (4) The inclined guide block will guide the rainwater collected above the main working column to the inside of the water storage tank when it is rainy outside. The water storage tank will store the rainwater. When the main working column generates a lot of heat during operation, the expansion air bag will expand due to the heat, thereby pushing the baffle to move laterally, so that the interface is connected to the drain outlet at the bottom of the water storage tank. The stored rainwater will enter the conveying block and enter the condenser tube through the conveying pipe. At this time, the rainwater inside the condenser tube will cool down the internal components of the main working column, reducing the possibility of the components being damaged due to excessive heat in the main working column. (5) When rainwater flows downhill, its potential energy will impact the striking plate, causing the striking plate to drive the rotating shaft to rotate. At the same time, the rotating shaft can reciprocate under the action of the torsion spring. While the striking plate is rotating, it will simultaneously strike the vibrating plate, causing the vibrating plate to vibrate, thereby driving the main working column to vibrate, further reducing the possibility of dust sticking to the outer wall of the main working column.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 6 The technical solution shown herein provides the following technical solution: Based on an anti-interference facial recognition access control device for smart campuses, an auxiliary fixing mechanism is disclosed. The auxiliary fixing mechanism and the locking block 10 cooperate to fix the main working column 3. Side fixing plate 2 is fixedly connected to the left and right sides of the upper surface of the placement platform 1, and a locking block 10 is fixedly connected to the inner side of the side fixing plate 2, and an auxiliary fixing mechanism is provided inside the placement platform 1; supplementary lights 6 are fixedly connected to the front of the outer surfaces of the main working column 3 and the side working column 4, and a rangefinder 7 is also fixedly connected to the outer surface of the main working column 3. The main working column 3 is fixedly connected to a first telescopic rod 21, and the output end of the first telescopic rod 21 is fixedly connected to an identification panel 8. The identification panel 8 is nested inside the main working column 3. The main working column 3 is fixedly connected to a cleaning brush 22, and the outer end of the cleaning brush 22 is in contact with the front side of the identification panel 8. The main working column 3 has horizontal slots 11 on its left and right sides, and a vertical slot 12 is opened on the upper side of the horizontal slots 11. The vertical slot 12 is nested inside a locking block 10. The bottom side of the placement slot 13 is fixedly connected to a limiting slot 17, and a limiting plate 18 is nested inside the limiting slot 17. The upper side of the limiting plate 18 is fixedly connected to an inclined plate 16. The inclined plate 16 is internally threaded with a threaded rod 15, and the outer end of the threaded rod 15 is nested and connected to the right side of the placement platform 1. The outer end of the threaded rod 15 is fixedly connected to a motor 14. A sliding groove 19 is provided on the upper side of the inclined plate 16, and a limiting ball 20 is connected to the inner front of the sliding groove 19. The upper end of the limiting ball 20 is fixedly connected to the bottom end of the main working column 3. The limiting plate 18 and the inclined plate 16 are integrated structures, and the inclined plate 16 forms a sliding structure through the threaded rod 15. The inclined plate 16 drives the main working column 3 to form a sliding structure through the limiting ball 20. The horizontal slot 11 and the vertical slot 12 are interconnected and are symmetrically distributed about the center point of the main working column 3.

[0022] The rangefinder 7 detects the distance to the person's position. When a person is standing in front of the device and identification is required, the rangefinder 7 will activate the first telescopic rod 21 when it detects a close distance. At this time, the first telescopic rod 21 will move the identification panel 8 upward, so that the identification panel 8 extends from the inside of the main working column 3 to detect the person's face. At the same time, the supplementary light 6 will provide supplementary lighting for the person, reducing the possibility of identification difficulties in dim environments. When the identification is completed, the first telescopic rod 21 will move the identification panel 8 back. At this time, the moving identification panel 8 will synchronously drive the cleaning brush 22 to rotate, and the cleaning brush 22 will clean the dust on the surface of the identification panel 8, reducing the possibility of dust residue affecting subsequent identification. When installing the main working column 3, the user can engage it with the engaging block 10 through the transverse slots 11 on both sides of the main working column 3 until the main working column 3 is placed inside the placement slot 13, so that the limiting ball 20 at the bottom of the main working column 3 engages with the sliding groove 19. At this time, the user can start the motor 14, which drives the threaded rod 15 to rotate. When the threaded rod 15 rotates, it will simultaneously drive the inclined plate 16 to slide laterally. During the sliding process, the inclined plate 16 will pass through its bottom... The fixedly connected limiting plate 18 slides within the limiting groove 17. As the inclined plate 16 moves to one side, the main working column 3 rises synchronously through the limiting ball 20. At this time, the locking block 10 enters the vertical locking groove 12 under the action of the rising position of the main working column 3. The vertical locking groove 12 and the locking block 10 cooperate with each other, and under the limiting action of the side fixing plate 2, the stability of the main working column 3 can be further improved, while also facilitating the subsequent quick disassembly and maintenance of the main working column 3 by the staff. Example 2

[0023] like Figure 1 , Figure 4 and Figure 5 The technical solution shown herein provides the following technical solution: Based on an anti-interference facial recognition access control device for smart campuses, a range adjustment mechanism is disclosed. This range adjustment mechanism, driven by the second telescopic rod 24, can adjust the detection range of the detection element 23. The placement platform 1 has a placement slot 13 inside, and a main working column 3 is nested inside the placement slot 13. A baffle 5 is nested on the side of the main working column 3. The access control device also includes a side working column 4, which is correspondingly arranged on the side of the main working column 3. The detection element 23 is fixedly connected inside the detection head 9, and a second telescopic rod 24 is fixedly connected to the upper end of the inside of the detection head 9. The output end of the second telescopic rod 24 is provided with a range adjustment mechanism. The output end of the second telescopic rod 24 is fixedly connected to an auxiliary plate 30, and the left and right sides of the auxiliary plate 30 are hinged to rotating rods 25, and the other end of the rotating rods 25 is hinged to a driving plate 26; the lower end of the inside of the detection head 9 is fixedly connected to a limit rod 29, the lower end of the driving plate 26 is fixedly connected to an adjusting plate 27, and the lower end of the adjusting plate 27 is fixedly connected to a connecting rod 28, and the bottom end of the connecting rod 28 is nested and connected to the outside of the limit rod 29; the sides of the adjusting plate 27 are arc-shaped, and the position of the adjusting plate 27 corresponds to that of the detection element 23. The rotating rod 25 drives the adjusting plate 27 through the driving plate 26 to form a sliding structure.

[0024] When there are many people behind the person being tested and the background is cluttered, the second telescopic rod 24 starts to operate, synchronously pushing the auxiliary plate 30 to move. At this time, both ends of the rotating rod 25 rotate under the action of the auxiliary plate 30. When the outer end of the rotating rod 25 rotates, it will synchronously drive the adjusting plate 27 to move through the driving plate 26. When the adjusting plate 27 moves, it will synchronously drive the connecting rod 28 at the bottom to move on the limiting rod 29, further making the movement of the adjusting plate 27 more stable. When the adjusting plate 27 moves, it will block the detection element 23 to a certain extent, so that the detection element 23 only performs face recognition processing on the people who are closer, which reduces the possibility of cluttered people behind the detection to a certain extent. Example 3

[0025] like Figure 1 , Figure 7 and Figure 8 The technical solution shown herein provides the following technical solution: Based on an anti-interference facial recognition access control device for smart campuses, a cooling vibration mechanism is disclosed, which can cool down the main working column 3: A flow guide block 31 is fixedly connected to the top of the main working column 3, and a water tank 32 is fixedly connected to the rear side of the main working column 3. A cooling vibration mechanism is provided on the rear side of the main working column 3. An expansion air bladder 41 is nested at the bottom of the water tank 32, and a baffle plate 42 is fixedly connected to the inner side of the expansion air bladder 41. An interface 43 is provided on the inner side of the baffle plate 42. A rotating shaft 33 is nested at the rear side of the main working column 3, and a torsion spring 34 is fixedly connected to the outer side of the rotating shaft 33. The other end of the torsion spring 34 is fixedly connected to the outer side of the main working column 3. At the same time, striking plates 35 are fixedly connected to the left and right sides of the rotating shaft 33, and a vibrating plate 40 is fixedly connected to the outer rear side of the main working column 3. A conveying block 36 is fixedly connected to the rear side of the main working column 3, and a conveying pipe 37 is connected through the bottom end of the conveying block 36. A condenser pipe 38 is connected through the inner side of the conveying pipe 37, and a drain pipe 39 is connected through the bottom end of the condenser pipe 38. The drain pipe 39 extends to the outer end of the main working column 3. The striking plate 35 is connected to the drain outlet of the water tank 32. The rotating shaft 33 forms a rotating structure with the main working column 3 through the striking plate 35. The condenser pipe 38 is connected through the inside of the main working column 3, and the condenser pipe 38 is U-shaped when viewed from the side.

[0026] The inclined guide block 31, during rainy weather, directs rainwater collected above the main working column 3 to the water storage tank 32, where it stores the rainwater. When the main working column 3 generates significant heat during operation, the expansion bladder 41 expands, pushing the baffle 42 laterally. This aligns the interface 43 with the drain outlet at the bottom of the water storage tank 32, allowing the stored rainwater to flow into the conveying block 36 and then through the conveying pipe 37 into the condenser pipe 38. Rainwater can cool down the internal components of the main working column 3, reducing the possibility of damage caused by excessive heat. When the rainwater flows downhill, its potential energy impacts the striking plate 35, causing the striking plate 35 to drive the rotating shaft 33 to rotate. At the same time, the rotating shaft 33 can reciprocate under the action of the torsion spring 34. While the striking plate 35 is rotating, it will simultaneously strike the vibrating plate 40, causing the vibrating plate 40 to vibrate, thereby driving the main working column 3 to vibrate, further reducing the possibility of dust sticking to the outer wall of the main working column 3.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
