Description

Technical Field

[0001] This utility model relates to the field of access control technology, specifically to a physical access control device that links identity authentication and access control. Background Technology

[0002] Access control refers to the restrictions on access to a door, serving as a means of security and prevention. In a broad sense, "door" here includes all kinds of passageways, such as doors for people and doors for vehicles.

[0003] A Chinese utility model patent (Announcement No.: CN222300092U) discloses an intelligent access control facial recognition device, relating to the field of facial recognition technology. The device includes a security door and a facial recognition machine. Through the arrangement of a moving rack and pinion, the tilt angle of the facial recognition machine can be adjusted according to the user's height. When the user is shorter, pressing down on the control lever indirectly tilts the facial recognition machine downwards; when the user is taller, raising the control lever indirectly tilts the facial recognition machine upwards. This allows the intelligent access control facial recognition device to flexibly adapt to the height differences of different people, thereby improving recognition efficiency and eliminating the need for users to bend over or stand on tiptoe. The spring mechanism uses its resistance to fix the position of the sliding block. When the control lever loses external force, the spring quickly returns to its original shape, indirectly resetting the facial recognition machine and ensuring stability and accuracy during the recognition process. This provides a convenient and reliable operating environment for subsequent recognition.

[0004] However, in implementing the relevant technology, the above-mentioned intelligent access control facial recognition device has the following problems: The above technical solution relies on a spring-reset facial recognition machine. After long-term use, the spring is prone to deformation, which leads to inaccurate reset of the facial recognition machine and affects the recognition accuracy. Therefore, a physical access control device that links identity authentication and access control is proposed. Utility Model Content

[0005] This invention proposes a physical access control device that links identity authentication and access control, solving the problem in related technologies where springs easily deform after long-term use, leading to inaccurate resetting of the face recognition machine and affecting recognition accuracy.

[0006] The technical solution of this utility model is as follows: A physical access control device that links identity authentication and access control, comprising: Main control unit; An isolation mechanism is installed on one side of the main control unit. A housing is fixedly installed on one side of the main control unit, and an identity authentication component is rotatably connected to one side of the housing. An L-shaped plate is slidably connected inside the box, and rods are fixedly installed at both the top and bottom of the L-shaped plate; The cylinders are all fixedly installed on one side of the inner wall of the box body, one end of the rod extends into the inside of the cylinder, and a reset component is provided inside the cylinder; Baffles, all of which are detachably connected to the top and bottom of the housing.

[0007] Preferably, the main controller is internally equipped with a control module and an access control decision module, and the access control decision module and the isolation mechanism are electrically connected to the control module.

[0008] Preferably, the identity authentication component includes an authentication body, a face recognition camera, and a fingerprint reader. The authentication body is rotatably connected to one side of the housing. The face recognition camera and the fingerprint reader are respectively fixedly installed through the surface of the authentication body. The face recognition camera and the fingerprint reader are electrically connected to the control module.

[0009] Preferably, a rotating rod is rotatably connected through the inside of the housing, a gear is fixedly installed on the outer side wall of the rotating rod, and one end of the rotating rod is fixedly connected to one side of the authentication machine.

[0010] Preferably, a toothed plate is fixedly installed on one side of the L-shaped plate, and the toothed plate is meshed with the gear.

[0011] Preferably, a frame is fixedly installed on one side of the box, a bidirectional screw is rotatably connected inside the frame, plates are slidably connected to both sides of the inner wall of the frame, and a locking block is fixedly installed on the top of the plate.

[0012] Preferably, the top of the baffle has a slot that matches the card block.

[0013] The working principle and beneficial effects of this utility model are as follows: 1. By setting up a baffle, a reset component and a cylinder, the baffle is removed and the reset component inside the cylinder is taken out. A new reset component is placed inside the cylinder and the baffle is installed on the box body to replace the reset component. This solves the problem in the existing technology that the spring is prone to deformation after long-term use, which leads to inaccurate reset of the face recognition machine and affects the recognition accuracy.

[0014] 2. Through the set control module, access control decision module, fingerprint reader and face recognition camera, the face recognition camera captures a face or a fingerprint is pressed on the fingerprint reader. The face or fingerprint information is transmitted to the control module for identity authentication. After the identity authentication is successful, the control module calls the access control decision module to determine whether the current time, the user's permissions and other conditions meet the access requirements. After both identity authentication and permission judgment are successful, the isolation mechanism is opened through the control module for passage. Attached Figure Description

[0019] Please see Figure 1 - Figure 4 This utility model provides a physical access control device for linkage identity authentication and access control, including: a main control unit 1; an isolation mechanism 2, which is a rotating gate in the prior art access control, installed on one side of the main control unit 1, a housing 3 fixedly installed on one side of the main control unit 1, an identity authentication component 4 rotatably connected to one side of the housing 3, the identity authentication component 4 realizing two authentication methods, an L-shaped plate 5, the L-shaped plate 5 is slidably connected inside the housing 3, a rod 6 is fixedly installed on the top and bottom of the L-shaped plate 5, a cylinder 7 is fixedly installed on one side of the inner wall of the housing 3, one end of the rod 6 extends into the inside of the cylinder 7, a reset component 8 is provided inside the cylinder 7, the reset component 8 is a spring, and a baffle 9, the baffle 9 can be detachably connected to the top and bottom of the housing 3; The identity authentication component 4 captures a face or a fingerprint on its surface, and the face or fingerprint information is transmitted to the main control unit 1 for identity authentication. After the identity authentication is successful, the main control unit 1 controls the opening of the isolation mechanism 2 to allow passage.

[0020] In this embodiment, as Figure 1 and Figure 4 As shown, the main control unit 1 is equipped with a control module and an access control decision module. The access control decision module and the isolation mechanism 2 are electrically connected to the control module. The identity authentication component 4 includes an authentication body 41, a face recognition camera 42 and a fingerprint reader 43. The authentication body 41 is rotatably connected to one side of the housing 3. The face recognition camera 42 and the fingerprint reader 43 are respectively fixedly installed on the surface of the authentication body 41. The face recognition camera 42 and the fingerprint reader 43 are electrically connected to the control module. In use, the face recognition camera 42 captures a face or a fingerprint is pressed on the fingerprint reader 43. It supports two authentication methods, and users can choose one or set it to dual authentication.
