Description

Technical Field

[0001] This invention relates to the field of building security management equipment, and more particularly to an intelligent facial recognition access control device. Background Technology

[0002] Building access control systems are an effective security measure for important areas. Evolved from traditional door locks, they provide excellent protection for the property and personal safety of personnel within the access control area. They offer advantages such as simplified management, reduced workload for security personnel, and increased work efficiency. Facial recognition is a biometric technology that identifies individuals based on facial features. It uses cameras or webcams to capture images or video streams containing faces, automatically detects and tracks faces within the images, and then performs facial recognition. This comprehensive technology effectively improves access control efficiency.

[0003] In existing technologies, facial recognition access control systems typically use fixed cameras at the access point, resulting in a fixed height and thus a fixed facial recognition area. When a person trying to pass through the access control is taller than the camera's facial recognition area, it is difficult to obtain their facial information. Furthermore, when someone attempts to climb over the access control barrier, existing fixed access control cameras struggle to track and record their facial information, posing certain security risks.

[0004] In view of this, it is necessary to improve the existing facial recognition access control equipment to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to disclose an intelligent facial recognition access control device to solve the problems of existing facial recognition cameras fixed at access control channels having a fixed recognition area, making it difficult to adapt to the facial recognition needs of people outside the recognition area, and failing to track and record the facial information of people who climb over the access control, which poses certain security risks.

[0006] To achieve the above objectives, the present invention provides an intelligent facial recognition access control device, comprising: an access control device body and a facial acquisition component, wherein the access control device body includes a device frame and an access control partition, and the device frame is rotatably connected to the access control partition via a first drive component;

[0007] The first drive assembly includes a first drive motor, a connecting device, and a support slide rod. The support slide rod is arranged along the height direction of the equipment frame and is coaxially fixed to the drive end of the first drive motor. The support slide rod drives the access control partition to rotate to a length direction perpendicular to the equipment frame. The connecting device is fixed to the lower surface of the first drive motor and fits against the top of the access control partition. When the top of the access control partition is under pressure, it moves down along the support slide rod and disengages from the connecting device.

[0008] A linkage assembly is provided between the access control partition and the face acquisition component. As the access control partition moves down along the support slide bar, the linkage assembly drives the face acquisition component to rotate toward the access control partition. The face acquisition component has a display screen, and an image acquisition device is provided on both the upper and lower sides of the display screen.

[0009] As a further improvement of the present invention, it also includes: a second drive assembly, the second drive assembly including a second drive motor and a lead screw coaxially fixed with the drive end of the second drive motor, the access control partition having a sleeve, the outer wall of the sleeve having a threaded groove that engages with the lead screw;

[0010] The connecting device is configured as an adsorption magnetic ring, the sleeve slides and engages with the support slide rod and its top end is magnetically attracted to the connecting device, and the equipment frame is fixedly connected to the guide ring around the bottom end of the support slide rod;

[0011] The inner wall of the sleeve is fixed to a guide plate. The support slide rod has a guide groove along the height direction that slides and cooperates with the guide plate. The guide ring forms a guide slope facing away from the face collection device. During the process of the guide plate sliding towards the bottom of the guide groove, the sleeve slides into the guide ring. The access control partition is guided by the guide slope to rotate towards the direction close to the second lead screw so that the screw groove engages with the lead screw.

[0012] As a further improvement of the present invention, the linkage assembly includes a first linkage, a second linkage, a third linkage and a rotating shaft, wherein the first linkage passes through the connecting device and is slidably engaged, and the top end of the sleeve is in contact with the bottom surface of the first linkage and the bottom end of the connecting device;

[0013] The third link is fixed to the top surface of the first drive motor. One end of the second link is rotatably connected to the third link, and the other end has an oblong hole along its length for the rotating pin of the first link to pass through. The side of the second link away from the first drive motor along its length is rotatably connected to the drive gear.

[0014] The rotating shaft has several concave teeth that mesh with the drive gear at one end along its length. The end of the rotating shaft away from the drive gear is connected to a first bevel gear. The bottom wall of the face acquisition component is vertically fixed to a connecting shaft. The connecting shaft passes through the device frame and has a second bevel gear that meshes with the first bevel gear.

[0015] As a further improvement of the present invention, the connecting shaft is provided with a first spring sleeved at one end inside the equipment frame. The first spring is a torsion spring, one end of which abuts against the second bevel gear, and the other end abuts against the inner wall of the equipment frame.

[0016] As a further improvement of the present invention, the second driving component further includes: a sensing component, the sensing component including a connecting frame and a sensing mechanism, the sensing mechanism including a pressure plate, a slide rod and a conductive sheet, the top wall of the connecting frame having a receiving cavity, the slide rod passing through the receiving cavity and slidingly engaging with the receiving cavity;

[0017] The top wall of the connecting frame is provided with an electrode sheet around the receiving cavity. The pressure plate is fixed to the top wall of the slide rod. The conductive sheet is connected to the slide rod and located below the pressure plate. The pressure plate is driven by the pressure of the second connecting rod to move the conductive sheet downward and fit it against the electrode sheet.

[0018] As a further improvement of the present invention, a second spring is fixed to the bottom wall of the receiving cavity, and the top end of the second spring extends upward and abuts against the bottom wall of the slide rod.

[0019] As a further improvement of the present invention, the face acquisition component has a rotating slot on the upper and lower sides of the display screen along the width direction, and the two image acquisition devices are rotatably connected in one rotating slot.

[0020] As a further improvement of the present invention, the image acquisition device includes: a camera body and a rotating motor, the rotating motor driving the camera body to rotate about the length direction of the rotating groove as an axis, the camera body being connected to the rotating groove through a camera assembly and the camera body being disposed at the opening of the rotating groove, and the rotation angle of the rotating motor being controlled by the camera assembly.

[0021] As a further improvement of the present invention, the face acquisition component has a face recognition module and a control module. The face recognition module acquires face image information, and the control module receives the face image information and compares it with cloud image information to control the opening and closing of the access control partition.

[0022] As a further improvement of the present invention, it also includes: multiple fences, multiple sets of equipment frames arranged side by side, an access control partition between every two equipment frames, and multiple equipment frames arranged between multiple fences.

[0023] Compared with existing technologies, the beneficial effects of this invention are as follows: First, the access control partition is opened and closed by a first drive motor and a support slide rod. It opens when a person passes through the facial recognition component for authentication, achieving the purpose of verifying the person's identity and providing good security. When an attempt is made to climb over the access control barrier, the top of the partition is disengaged from the connecting device and moves downwards along the support slide rod. During this process, the facial recognition component rotates towards the partition, thereby tracking and collecting the facial information of the person attempting to climb over the barrier, thus improving the security performance of the access control system. Furthermore, the image acquisition devices located on the upper and lower sides of the facial recognition component increase the facial image acquisition range.

[0024] Secondly, through the second drive motor and lead screw constituting the second drive assembly, and the guide slope of the guide ring, when the access control partition moves to the bottom end of the support slide, it rotates under the guidance of the guide surface of the guide ring until it engages with the screw groove of its sleeve. The second drive motor is then started to drive the lead screw to rotate and drive the access control partition to rise to the top of the sleeve and engage with the connecting device again.

[0025] Finally, when the access control partition moves down along the support slide bar, the bottom end of the first link loses the thrust from the sleeve and sinks, causing the end of the second link connected to the first link to move down, thereby driving the gear connected to the second link to drive the rotating shaft to rotate through the concave teeth, and then driving the face acquisition component to rotate towards the direction closer to the access control partition through the first bevel gear and the second bevel gear.

[0037] The present invention will be described in detail below in conjunction with the embodiments shown in the drawings. It should be noted, however, that these embodiments are not intended to limit the present invention, and any equivalent transformation or substitution in terms of function, method, or structure made by those of ordinary skill in the art based on these embodiments shall fall within the protection scope of the present invention.

[0038] Refer Figures 1 to 11 As shown, this is a specific embodiment of an intelligent face recognition access control device designed by the present invention. Compared with the existing face recognition access control devices, the opening and closing of the access control partition 12 are driven by the first drive motor 131 and the support slide bar 132. When a person passes the authentication of the face collection component 2, it opens to achieve the purpose of verifying the identity of the personnel by the access control device and playing a good security role. When there is an attempt to翻越 the access control, the top of the access control partition 12 is stressed and separated from the connecting device and moves down along the support slide bar 132. During this process, it带动 the face collection component 2 to rotate towards the direction close to the access control partition 12, so as to achieve the purpose of tracking and collecting the facial information of the person who翻越 the access control for the tracking of this person, thereby improving the security performance of the access control. In addition, the image acquisition devices 21 arranged on the upper and lower sides of the face collection component 2 are used to increase the face image acquisition range, thereby further improving the authentication efficiency of the access control device for the facial information of the personnel.

[0039] Refer Figures 1 to 11 It should be noted that the term "翻越" in the original text seems to be incorrect or an incomplete expression. It may need to be further clarified or corrected in the original context.As shown in the figure, the intelligent face recognition access control device (hereinafter referred to as the access control device) in this embodiment includes an access control device main body 1 and a face collection component 2. The access control device main body 1 includes a device frame 11 and an access control partition 12. The device frame 11 is rotationally connected to the access control partition 12 through a first driving component 13. The first driving component 13 includes a first driving motor 131, a connecting device 132, and a support slide bar 133. The support slide bar 133 is arranged along the height direction of the device frame 11 and is coaxially fixed to the driving end of the first driving motor 131. The support slide bar 133 drives the access control partition 12 to rotate perpendicular to the length direction of the device frame 11. The connecting device 132 is fixedly connected to the lower surface of the first driving motor 131 and fits with the top end of the access control partition 12. When the top of the access control partition 12 is subjected to pressure, it moves down along the support slide bar 133 and disengages from the connecting device 132. A connecting rod component 3 is arranged between the access control partition 12 and the face collection component 2. During the process of the access control partition 12 moving down along the support slide bar 133, the connecting rod component 3 drives the face collection module 2 to rotate towards the direction close to the access control partition 12. The face collection component 2 has a display screen 22, and an image collection device 21 is provided on both the upper and lower sides of the face collection component 2 where the display screen 22 is located. The access control device further has: a plurality of fences 4. Multiple groups of device frames 11 are arranged in parallel. An access control partition 12 is arranged between every two device frames 11. The multiple device frames 11 are arranged between the multiple fences 4.

[0040] See Figures 1 to 7As shown, the connecting device 132 is configured as an adsorption magnetic ring. The sleeve 121 slides and engages with the support slide rod 133, and its top end magnetically engages with the connecting device 132. The guide plate 123 is fixedly connected to the inner wall of the sleeve 121. The support slide rod 133 has a guide groove 1331 along its height direction that slides and engages with the guide plate 123. The connecting rod assembly 3 includes a first connecting rod 31, a second connecting rod 32, a third connecting rod 33, and a rotating shaft 34. The first connecting rod 31 passes through the connecting device 132 and slides and engages with it. The top end of the sleeve 121 is in contact with the bottom surface of the first connecting rod 31 and the bottom end of the connecting device 121. The third connecting rod 33 is fixedly connected to the top surface of the first drive motor 131. One end of the second connecting rod 32 is rotatably connected to the third connecting rod 33, and the other end has a waist-shaped hole (not marked) along its length direction to allow the first connecting rod 31 to rotate. A pin (not shown) passes through the second connecting rod 32, which is rotatably connected to the drive gear 321 on the side of its length away from the first drive motor 131. A shaft 34 has several recessed teeth around its perimeter 341 at one end in the length direction, meshing with the drive gear 321. The end of the shaft 34 away from the drive gear 321 is connected to the first bevel gear 342. A connecting shaft 23 is vertically fixed to the bottom wall of the face acquisition component 2. The connecting shaft 23 passes through the device frame 11 and connects to the second bevel gear 231, which meshes with the first bevel gear 342. A first spring 232 is fitted onto one end of the connecting shaft 23 within the device frame 11. The first spring 232 is a torsion spring, with one end abutting against the second bevel gear 231 and the other end abutting against the inner wall of the device frame 11.

[0041] When personnel pass through the access control equipment normally, the image acquisition device 21 located above or below the face acquisition component 2 can be activated to capture the person's image, depending on the person's height. After successful verification, the first drive component 13 drives the access control partition 12 to rotate from a position perpendicular to the length of the equipment frame 11 to a position forming an acute angle of no more than 10° with the length of the equipment frame 11 to allow personnel to pass through. This provides the face acquisition component 2 with a larger field of view, improving the face recognition efficiency of the access control equipment (the specific state and the state of the face acquisition component 2 are as follows). Figure 3 and Figure 4As shown. When there is a situation of climbing over the access control, the access control partition 12 is subjected to upward pressure, causing the top end of the sleeve 121 fixed to it to disengage from the suction state with the connecting device 132. At this time, the bottom end of the first link 31 loses the thrust from the sleeve 121, resulting in its sinking under gravity, that is, it moves downward along its height direction within the connecting device 132. At the same time, the first link 31 pulls the end of the second link 32 connected to it to rotate downward with the end connected to the third link 33 as the axis, thereby causing the driving gear 321 connected to the second link 32 to move downward and engage with the concave teeth 341 formed on the rotating shaft 34 and rotate relatively. Since the concave teeth 341 are engaged with the driving gear 321, during the relative rotation of the concave teeth 341 and the driving gear 321, the rotating shaft 34 is driven to rotate in the opposite direction to the driving gear 321. The first bevel gear 342 connected to the other end of the rotating shaft 34 drives the second bevel gear 231 engaged with it to rotate, thereby causing the connecting shaft 23 to drive the face collection component 2 from Figure 4 the state shown in the figure to rotate and open, so as to track and obtain the facial information of the person climbing over the access control for evidence collection and subsequent positioning of the person through building monitoring, further improving the safety performance of the access control device. When the sleeve 121 is suctioned to the connecting device 132 again, the first link 31 is pushed upward by the sleeve 121, and the second link 32 drives the driving gear 321 to disengage from the state of engaging with the concave teeth 341 (see Figure 6 the figure shown). At this time, the first spring 232 returns to the unloaded state and drives the second bevel gear 231 to rotate in the reverse direction. The second bevel gear 231 drives the rotating shaft 34 back to the position waiting to engage with the driving gear 321 through the first bevel gear 342 engaged with it.

[0042] See Figures 1 to 10As shown, the intelligent face recognition access control device also includes a second drive assembly 14, which includes a second drive motor 141 and a lead screw 142 coaxially fixed to the drive end of the second drive motor 141. The access control partition 12 has a sleeve 121, and the outer wall of the sleeve 121 has a screw groove 122 that engages with the lead screw 142. The device frame 11 is fixedly connected to a guide ring 111 around the bottom end of the support slide rod 133. The guide ring 111 forms a guide slope 112 facing away from the face acquisition device 2. During the process of the guide plate 123 fixed inside the sleeve 121 sliding towards the bottom end of the guide groove 1331, the sleeve 121 slides into the guide ring 111. The access control partition 12 is guided by the guide slope 112 to rotate towards the direction close to the second lead screw 142 so that the screw groove 122 engages with the lead screw 142. The second driving assembly 14 further includes a sensing assembly 143, which includes a connecting frame 1434 and a sensing mechanism (not labeled). The sensing mechanism includes a pressure plate 1431, a slide rod 1432, and a conductive sheet 1433. A receiving cavity 1435 is formed in the top wall of the connecting frame 1434. The slide rod 1432 passes through the receiving cavity 1435 and slides in cooperation with the receiving cavity 1435. An electrode sheet 1436 is arranged around the receiving cavity 1435 on the top wall of the connecting frame 1434. The pressure plate 1431 is fixed to the top wall of the slide rod 1432. The conductive sheet is connected to the slide rod 1432 and located below the pressure plate 1431. The pressure plate 1431 is driven by the pressure of the second connecting rod 32 to move the conductive sheet 1433 downward and make it fit with the electrode sheet 1436. A second spring 1437 is fixed to the bottom wall of the receiving cavity 1435. The top end of the second spring 1437 extends upward and abuts against the bottom wall of the slide rod 1432.

[0043] After the access control partition 12 is disengaged from the connecting device 132 under the force above it, as it slides down along the support slide rod 133, the guide plate 123 connected to the inner wall of the sleeve 121 slides along the guide groove 1331 opened in the support slide rod 133. When the sleeve 121 of the access control partition 12 slides into the guide ring 111, the lower edge of the access control partition 12 is guided by the guide slope 112 formed in the guide ring 111. The guide plate 123 applies force to the guide groove 1331 to make the support slide rod 133 move with the access control partition 12 in a direction away from the face collection component 2, until the sleeve 121 is in the direction of the face collection component 2. Figure 5 The partition plate 12 is fully embedded in the guide ring 111, and its length is parallel to that of the equipment frame 11. The threaded groove 122 formed on the outer wall of the sleeve 121 engages with the screw 142. During this process, the support slide rod 133 rotates together with the partition plate 12. It should be noted that... Figures 6 to 8 As shown, when the sleeve 121 and the connecting device 132 are engaged, the bottom end of the first connecting rod 31 is subjected to a thrust from the sleeve 121. Figure 6The state shown in the figure is such that at this time, the bottom end of the second connecting rod 32 does not contact the pressure plate 1431 of the induction component 143. Therefore, the second spring 1437 is in an unloaded state. The conductive sheet 1433 connected to the slide bar 1432 does not contact the electrode sheet 1435 provided around the notch of the accommodation cavity 1435, and the power supply of the second drive motor 14 is in an unconnected state, and the lead screw 142 is in a stationary state. When the sleeve 121 disengages from the connecting device 132 and moves to be embedded in the guiding ring 111, the bottom end of the first connecting rod 31 loses the thrust from the sleeve 121 and moves down to Figure 7 The state shown in the figure is such that at this time, the bottom end of the second connecting rod 32 applies pressure to the pressure plate 1431 of the induction component 143 to cause the slide bar 1432 to move down in the accommodation cavity 1435. The second spring 1437 is compressed under force. After the conductive sheet 1433 connected to the slide bar 1432 fits with the electrode sheet 1435 provided around the notch of the accommodation cavity 1435, the power supply circuit of the second drive motor 141 is turned on. The drive end of the second drive motor 141 drives the lead screw 142 to rotate. Due to the meshing relationship between the thread groove 122 formed on the outer wall of the sleeve 121 and the lead screw 142, the sleeve 121 rises along the support slide bar 133 during the rotation of the lead screw 142 until the top end of the sleeve 121 is again attracted to the connecting device 132. At this time, since the pressure plate 1431 loses the pressure from the second connecting rod 32, the second spring 1437 returns to the unloaded state to push the conductive sheet 1433 away from the electrode sheet 1436 to cut off the power supply circuit of the second drive motor 141. Since the connecting device 132 is set as an adsorption magnetic ring in this embodiment, the top end of the sleeve 121 is made of a metal material capable of being attracted to the magnetic part. Then, the first drive motor 131 is started again to drive the support slide bar 133 to drive the access control partition 12 to rotate to the state shown in Figure 3 and Figure 4 shown in the figure. It should be noted that the aforementioned pressure plate 1431, slide bar 1432, and connecting frame 1434 are all made of insulating materials. In this embodiment, the second drive motor 141 is connected to the lower surface of the first drive motor 131. Through the aforementioned structure, when the access control partition 12 disengages from the connecting device 132, during the process of the sleeve 121 moving into the guiding ring 111, the face acquisition component 2 has already completed the acquisition of the facial information of the person climbing over the access control device. The power supply of the second drive motor 141 is automatically turned on through the induction component 143 to make the access control partition 12 automatically rise and return to its position for further operation.

[0044] Refer Figure 9 and Figure 11As shown, the face acquisition component 2 has a rotating slot 24 on each of the upper and lower sides of the display screen 22 along its width direction. Two image acquisition devices 21 are rotatably connected to one of the rotating slots 24. The image acquisition device 21 includes a camera body 211 and a rotating motor 212. The rotating motor 212 drives the camera body 211 to rotate about the length direction of the rotating slot 24. The camera body 211 is connected to the rotating slot 24 through a camera component 213 and is positioned at the opening of the rotating slot 24. The camera component 213 controls the rotation angle of the rotating motor 211. The face acquisition component 2 has a facial recognition module 25 and a control module 26. The facial recognition module 25 acquires facial image information, and the control module 25 receives the facial image information and compares it with image information in the cloud to control the opening and closing of the access control partition 12.

[0045] By setting two sets of image acquisition devices 21 vertically, when a person undergoes facial image recognition through the face acquisition component 2, three-dimensional facial image acquisition can be achieved through the two camera bodies 211. Simultaneously, the two camera bodies 213 can control the rotation of two rotating motors 212 respectively. Furthermore, the camera bodies 213 can identify the person's height through their built-in infrared sensors or other sensors. Therefore, when the face acquisition component 2 acquires facial images of people of different heights, its control module 25 can individually control the camera body 211 of one set of image acquisition devices 21, or simultaneously control the rotation of the camera bodies 211 of both sets of image acquisition devices 21, effectively increasing the image area that the face acquisition component 2 can acquire. This allows the face acquisition component 2 to capture facial images of people of different heights. It should be noted that the image information acquired by the two sets of image acquisition devices 21 is transmitted to the facial recognition module 25, and the acquired facial information is presented as an image on the display screen 22.
