Here, the "door" generally includes various passages that can be passed through, including doors for people to pass through, doors for vehicles to pass through, etc. Generally speaking, for a community, access control for residents to walk through will be set at the entrance and exit. Such access control will utilize face recognition technology to capture the faces of pedestrians attempting to pass through and determine whether the pedestrians are residents of this community, and then control the opening or closing of the door.
[0003] However, the patents in the prior art have the following several disadvantages:
[0004] (1) Most of the existing utility model face recognition access control devices are equipped with sunshades to block sunlight and reflected light to prevent the acquisition camera from being affected, resulting in a slow acquisition process. However, when used outdoors, the light angle and intensity change throughout the day. The fixed sunshade cannot adapt to the change of the light angle, and can only play a weak role in blocking the reflected light. Moreover, at night when the light intensity is low, the face recognition access control device cannot easily capture the face, making it inconvenient to use at night. Summary of the Utility Model

When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are only examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.
[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0026] Embodiment 1:
[0027] Such as Figures 1 to 5As shown in the figure, an anti-reflection face recognition access control device includes: a device housing 1, a control module 2 is installed inside the device housing 1, a display screen 3 is fixedly installed on the front side of the device housing 1, photosensitive sensors 4 are fixedly installed on both sides of the display screen 3, a collection camera 5 is fixedly installed above the display screen 3, and induction fill lights 6 are fixedly installed on both sides of the collection camera 5; a sunshade adjustment component 7, the sunshade adjustment component 7 is arranged at the top of the device housing 1; a pressure sensing component 8, the pressure sensing component 8 is arranged inside the chute 702.
[0028] The sunshade adjustment component 7 includes: a sunshade base 701, an extended sunshade 703, a photosensitive sensor 704, a motor 705, a lead screw 706, a fixed ring 707, a slider 708 and a support rod 709. The sunshade base 701 is fixedly connected to the top of the device housing 1. A chute 702 is opened inside the sunshade base 701. The extended sunshade 703 is slidably connected inside the chute 702. The photosensitive sensor 704 is fixedly installed at the top of the extended sunshade 703. The motor 705 is fixedly installed inside the chute 702. The lead screw 706 is fixedly connected to the ends of the drive shafts on both sides of the motor 705. The thread directions of the lead screws 706 on both sides of the motor 705 are opposite. The fixed rings 707 are fixedly connected to both sides inside the chute 702. One end of the lead screw 706 is rotatably connected to the fixed ring 707. The slider 708 is threadedly connected to the outside of the lead screw 706, and the top and bottom of the slider 708 are slidably connected to the inside of the chute 702. The support rod 709 is rotatably connected between the extended sunshade 703 and the slider 708.
[0029] In the initial state, the extended sunshade 703 is completely retracted into the inside of the chute 702. As the sun moves, part of the sunlight and specular reflected light will irradiate the collection camera 5, affecting the collection of the portrait by the collection camera 5 and causing the access control to not open. At this time, the reflected light will also irradiate on the photosensitive sensor 4. The photosensitive sensor 4 transmits the collected data to the control module 2. The control module 2 controls the motor 705 to start, so that the lead screws 706 with opposite thread directions on both sides of the motor 705 start to rotate synchronously, driving the sliders 708 on both sides of the motor 705 to slide closer to each other, causing the support rod 709 to rotate and gradually pushing the extended sunshade 703 out of the chute 702. As the extended sunshade 703 is pushed out, the photosensitive sensor 704 is pushed out, and the reflected light irradiating on the photosensitive sensor 4 is reduced, causing the control module 2 to control the motor 705 to stop starting and lock the movement of the extended sunshade 703, reducing the influence of the reflected light on the collection camera 5.
[0030] The photosensitive sensor 1 can only be used to control the extension of the extended sunshade 703. The photosensitive sensor 2 can be used to control the retraction of the extended sunshade 703. As the light intensity decreases, the photosensitive sensor 2 transmits the collected data to the control module 2. The control module 2 controls the motor 705 to rotate in the reverse direction, so that the extended sunshade 703 retracts into the chute 702, increasing the light for the auxiliary acquisition camera 5 to collect.
[0031] The pressure sensing assembly 8 includes: a connecting pipe 801, a connecting rod 803, a pressing plate 804 and a spring 805. The connecting pipe 801 is fixedly connected to the pressure sensor 802 inside the chute 702. The pressure sensor 802 is fixedly connected to the inner tail end of the connecting pipe 801. The connecting rod 803 is fixedly connected to the tail end of the extended sunshade 703. The connecting rod 803 is slidably connected to the pipe orifice of the connecting pipe 801. The pressing plate 804 is fixedly connected to one end of the connecting rod 803. The pressing plate 804 is slidably connected to the inside of the connecting pipe 801. The spring 805 is fixedly connected between the pressing plate 804 and the pressure sensor 802.
[0032] When the extended sunshade 703 retracts, the connecting rod 803 drives the pressing plate 804 to slide in the connecting pipe 801 to compress the spring 805. The spring 805 applies pressure to the pressure sensor 802. When the pressure sensor 802 monitors the target pressure, the pressure sensor 802 transmits the monitored data to the control module 2. The control module 2 controls the induction fill light 6 to turn on, which is used to assist the acquisition camera 5 to collect human faces in dim light, so that this utility model is applicable to night use.
[0033] All the electrical components mentioned in this article are electrically connected to the external main controller and the 220V mains. And the main controller can be a conventional known device such as a computer for control. The detailed descriptions of the known functions and known components are omitted in the specific implementation manners of the present disclosure. To ensure the compatibility of the device, the adopted operation means are consistent with the parameters of the market instruments.
[0034] The display screen, pressure sensor, photosensitive sensor, induction fill light, control module and acquisition camera are all existing products on the market. Their connection methods and control methods are all prior arts and will not be elaborated here.
[0035] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
