Description

Technical Field

[0001] This application relates to the technical field of access control devices, and in particular to an access control device for intelligent building security. Background Technology

[0002] Currently, intelligent building security access control devices are intelligent access management systems that integrate modern information technology, automatic control technology, and security concepts. They are primarily used for identifying, verifying, and recording the behavior of personnel entering and exiting specific areas, thereby improving the overall security and management efficiency of the building. The main components include: identification terminals, access control gates, and management platform software. Access control gates are automated devices used to control personnel entering and exiting specific areas, typically combined with identification terminals such as card swiping, QR code scanning, facial recognition, and fingerprint recognition, as well as physical barriers, to achieve intelligent management of access permissions.

[0003] In related technologies, some access control gates typically have a gap between the gate and the ground, usually 10-20 centimeters. Since dust, garbage, and water tend to accumulate at the bottom of the gate, this gap facilitates cleaning by cleaning staff, as well as equipment maintenance and drainage. However, when unattended, stray cats and dogs may enter the building through the gap at the bottom of the gate, potentially causing a series of safety, hygiene, and management problems, thus posing a certain safety hazard. Utility Model Content

[0005] The intelligent building security access control device provided in this application adopts the following technical solution: A smart building security access control device includes a turnstile with a barrier plate rotatably mounted on it. A gap is left between the bottom of the barrier plate and the ground. An intercepting plate is rotatably mounted on the outer wall of the barrier plate facing the entrance of the turnstile, with the rotation axis of the intercepting plate horizontally positioned. The downward-flipping intercepting plate will block at intervals. A locking component is provided on the barrier plate to lock the upward-flipping intercepting plate onto the barrier plate.

[0006] Preferably, the gate is provided with clearance cavities located on both sides of the barrier plate, and the clearance cavities are located below the barrier plate; when the barrier plate is in a downward flipped state, the clearance cavities are located on the path of the barrier plate as it rotates with the barrier plate, and the clearance cavities are used to allow the barrier plate to rotate into the outside of the gate.

[0007] Preferably, the locking assembly includes a first magnet fixedly disposed on the interceptor plate and a second magnet fixedly disposed on the interceptor plate. The first magnet is located on the path along which the second magnet follows the interceptor plate as it flips upward, and the first magnet is used to attract the second magnet.

[0009] Preferably, a lifting element is provided on the side wall of the locking member away from the tension spring.

[0010] Preferably, the locking assembly also includes a third magnet disposed on the interceptor plate, and the interceptor plate is provided with a fourth magnet for attracting and fixing with the third magnet; when the interceptor plate is flipped down and blocks the gap, the third magnet and the fourth magnet attract and fix with each other.

[0016] The present application will be further described in detail below with reference to the accompanying drawings.

[0017] This application discloses an access control device for intelligent building security.

[0018] Reference Figure 1 , Figure 2 The intelligent building security access control device includes a turnstile 1, on which a motor-driven barrier 2 is rotatably mounted. A gap 3 is left between the bottom of the barrier 2 and the ground. A face recognition terminal 6 is installed on the side wall of the turnstile facing the entrance. The face recognition terminal 6 collects and analyzes facial features and compares them with a database to achieve functions such as personnel identification, access control, and attendance recording. The core modules of the face recognition terminal 6 include: a camera for capturing facial images; a display screen for displaying the camera's captured images; a face recognition algorithm module based on deep learning such as CNN to extract facial feature vectors and perform 1:1 comparison verification or 1:N retrieval and recognition; and a processor. When the face recognition terminal 6 successfully recognizes the visitor information, the barrier 2 will automatically open under the drive of the motor.

[0019] like Figure 1 , Figure 2 As shown, a cooling fan 7 is installed on the side wall of the gate 1 away from the face recognition terminal 6. Multiple air inlets 11 are also connected through the bottom of the gate 1. The cooling fan 7 establishes a directional airflow channel inside the gate 1 through air intake and exhaust, so as to expel hot air in time and continuously replenish cold air, avoid heat accumulation, and thus effectively control the internal temperature of the gate 1, ensure stable hardware operation and extend service life.

[0020] like Figure 1 , Figure 2As shown, a voice announcer 8 is also installed on the gate 1, located below the cooling fan 7. As an important human-machine interface component of the gate 1, the voice announcer 8 is mainly used to guide user operation through voice prompts, provide feedback on passage status, improve passage efficiency and user experience, and issue warnings in abnormal situations. Its structure mainly includes: a speaker for voice announcements, a voice chip storing pre-recorded audio or supporting real-time TTS synthesis, an audio amplifier circuit for amplifying sound signals, and a control interface that communicates with the main control board of the gate 1 via RS232, RS485, Wiegand, or GPIO.

[0021] like Figure 1 , Figure 2 As shown, an interceptor plate 4 is rotatably installed on the outer wall of the barrier plate 2 facing the entrance of the gate 1. The rotation axis of the interceptor plate 4 is set horizontally. The downward flipping interceptor plate 4 blocks the gap 3. Under the blocking of the interceptor plate 4, stray cats and dogs can be effectively prevented from entering the building through the gap 3 at the bottom of the barrier plate 2, thereby further improving the safety of the gate 1 and enhancing the protection level of the gate 1.

[0022] like Figure 1 , Figure 3 as well as Figure 4 As shown, a locking assembly 5 is provided on the barrier plate 2, which is used to lock the barrier plate 4 onto the barrier plate 2. The locking assembly 5 includes a first magnet 50 fixedly mounted on the barrier plate 4 and a second magnet 51 fixedly mounted on the barrier plate 2. The first magnet 50 is located on the path of the second magnet 51 as the barrier plate 4 flips upward. When the barrier plate 4 flips upward and is in contact with the outer wall of the barrier plate 2, the mutual attraction between the first magnet 50 and the second magnet 51 can attract and fix the barrier plate 4 to the outside of the barrier plate 2. By flipping the barrier plate 4 upward from the gap 3, the gap 3 left is convenient for cleaning personnel to clean, and also facilitates equipment maintenance and drainage.

[0023] like Figure 3 , Figure 4 As shown, the barrier plate 2 is provided with a perforation 20. The locking assembly 5 also includes a locking member 52 that is slidably disposed in the perforation 20 along the height direction of the barrier plate 2, and a tension spring 53 disposed in the perforation 20. The tension spring 53 extends and retracts along the sliding direction of the locking member 52. The upper end of the tension spring 53 is suspended and fixed to the bottom of the locking member 52, and the lower end of the tension spring 53 is suspended and fixed to the inner side wall of the perforation 20. The tension spring 53 is used to press the locking member 52 downward and fix it above the barrier plate 4 in the flipped-up state. The locking member 52 can more stably and reliably limit and fix the barrier plate 4 in the flipped-up state to the outside of the barrier plate 2.

[0024] like Figure 3 , Figure 4As shown, a lifting member 54 is fixedly provided on the side wall of the locking member 52 away from the tension spring 53. When it is necessary to release the locking member 52 from locking the interceptor plate 4, the lifting member 54 is pulled upward, and as the locking member 52 exits from above the interceptor plate 4, the locking of the interceptor plate 4 is released. At this time, the interceptor plate 4 can be flipped downward from the outside of the barrier plate 2.

[0025] like Figure 3 , Figure 4 As shown, the locking assembly 5 also includes a third magnet 55 fixedly mounted on the interceptor plate 4, and a fourth magnet 56 fixedly mounted on the interceptor plate 2 for attracting and fixing with the third magnet 55. The fourth magnet 56 is located on the path of the third magnet 55 as the interceptor plate 4 flips downward. When the interceptor plate 4 flips downward and blocks the gap 3, the mutual attraction between the third magnet 55 and the fourth magnet 56 can fix the interceptor plate 4 in the downward state to the outside of the interceptor plate 2. This improves the stability of the interceptor plate 4 in the downward state.

[0026] like Figure 2 , Figure 3 As shown, the turnstile 1 is provided with clearance cavities 10 located on the left and right sides of the barrier plate 2, respectively, with the clearance cavities 10 positioned below the barrier plate 2. When the barrier plate 4 is in the downward flipped state, the clearance cavities 10 are located on the path of the barrier plate 4 as it rotates with the barrier plate 2, allowing the barrier plate 4 to rotate into the outside of the turnstile 1. The clearance cavities 10 prevent the bottom of the turnstile 1 from interfering with the rotation of the barrier plate 4, ensuring that the barrier plate 4 can smoothly rotate and open with the barrier plate 2.

[0027] The implementation principle is as follows: the downward-flipping interceptor plate 4 blocks the gap 3, effectively preventing stray cats and dogs from entering the building through the gap 3 at the bottom of the barrier plate 2, thereby further improving the security of the gate 1 and enhancing its protection level. The interceptor plate 4, in its downward-flipped state, is fixed to the outside of the barrier plate 2 by the mutual attraction of the third magnet 55 and the fourth magnet 56, thus improving the stability of the interceptor plate 4 in its downward-flipped state.

[0028] By flipping the interceptor plate 4 upwards from the gap 3, the gap 3 is made easier for cleaning personnel to clean, and also facilitates equipment maintenance and drainage. The locking element 52 can more stably and reliably limit and fix the interceptor plate 4 in the flipped-up state to the outside of the barrier plate 2.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
