Description

Technical Field

[0001] The present invention relates to the technical field of gates, in particular to an intelligent recognition gate. Background Art

[0002] In the field of intelligent security, gates, as core protective devices at building entrances and exits, have long been a focus of research on their safety, convenience, and intelligence. With the development of IoT and biometric technologies, traditional mechanical locks, due to the vulnerability of key loss, are no longer able to meet modern security requirements. Intelligent identification gates, integrating biometric recognition with automated control technologies, have become a key solution for improving entrance and exit security management efficiency.

[0003] At present, smart doors on the market generally use a single identification method. They may not work properly in scenarios such as user finger injuries or facial obstructions, which can easily lead to traffic obstructions and lack a redundant verification mechanism. In addition, traditional drive structures often directly drive the movement of door panels, which can easily cause the two door panels to move out of sync, get stuck, or even derail, affecting the user experience and equipment life. They are also prone to problems such as reverse movement due to external forces, resulting in unstable opening and closing of door panels, and even the risk of getting stuck or opening accidentally. At the same time, the control logic of existing smart doors is relatively simple, lacking a linkage design between mechanical limits and electronic controls. Traditional drive methods lack a self-locking mechanism. When the device loses power or encounters an external force impact, the door panels may be forced open, posing a safety hazard. In other words, it is difficult to ensure the locked state of the door panels in the event of a power outage or system failure. Summary of the Invention

[0004] In response to the deficiencies in the prior art, the present invention provides an intelligent recognition door that solves the problem that the door may not be used normally in scenarios such as user finger injuries or facial obstructions.

[0008] Preferably, a camera for facial recognition, digital buttons for inputting digital passwords, and a fingerprint recognition element for identifying fingerprints are provided on the top side of the front end of the all-in-one machine.

[0009] Preferably, a baffle is fixedly connected to the bottom end of the door frame, and the front ends of the two door panels are both arranged at the rear end of the baffle.

[0010] Preferably, a display screen is fixedly connected to the front end of the all-in-one machine, and closing buttons are provided on the rear end of the control device and the front end of the all-in-one machine.

[0011] Preferably, the control device controls the start and stop of the motor and the forward and reverse rotation of its driving end through wireless data transmission.

[0012] Preferably, an intelligent identification system for intelligently identifying a door comprises the following steps:

[0013] Step 1: Users can authenticate their identity through any of the following methods: camera, digital button, or fingerprint recognition.

[0014] Step 2: The identification data is transmitted to the main control chip in the control device and compared with the preset database through an encryption algorithm for verification;

[0015] Step 3: After verification, the main control chip sends instructions to the motor via Bluetooth to control the motor's forward rotation, causing the two door panels to rotate open.

[0016] Preferably, in step one, the user's facial image can be captured by a camera for identity authentication, a preset digital password can be entered through a digital button for identity authentication, and fingerprint information can be collected by placing a finger on a fingerprint recognition element for identity authentication.

[0021] 2.

Even if the motor is powered off, the door panel cannot be forcibly pushed open by external force. Gear 1 and gear 2 are engaged to realize reverse transmission, so that the two door panels rotate relative to each other.

[0022] 3. The present invention can ensure that the rotating rod 1 and the rotating rod 2 rotate synchronously through the synchronous wheel 1, the synchronous belt and the synchronous wheel 2, and realize reverse transmission when the gear 1 and the gear 2 are engaged, so that the two door panels rotate relative to each other, avoiding the two door panels from getting stuck or colliding due to the speed difference.

[0023] 4.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Specifically, after motor 8 is started, it drives worm 9 to rotate and engage worm gear 10, driving rotating rod 11. Synchronous gear 12 on the outer wall of rotating rod 11 drives synchronous gear 2 14 via synchronous belt 13, rotating rotating rod 2 15. Gear 1 16 on rotating rod 2 15 engages with gear 2 17, driving rotating rod 3 18 to rotate in the opposite direction. Ultimately, rotating rod 11 and rotating rod 3 18 drive the two door panels 19 to rotate relative to each other and open. The stopper 20 at the top of the door panels slides within the stopper slot 21, ensuring a stable opening and closing trajectory.

[0035] Among them, the motor 8 is installed at the rear end of the door frame 1 through a fixed frame, and the driving end of the motor 8 is fixedly connected to the worm 9. The right side of the outer wall of the worm 9 is meshed with a worm wheel 10. The inner wall of the worm wheel 10 is fixedly connected to the outer wall of the rotating rod 11. The outer walls of the worm 9 and the worm wheel 10 are both rotatably connected to the inner wall of the door frame 1. Among them, the synchronous wheel 12 is located on the outer wall of the rotating rod 11. The outer wall of the synchronous wheel 12 is connected to the synchronous wheel 2 14 through a synchronous belt 13. The inner wall of the synchronous wheel 2 14 is fixedly connected to the outer wall of the rotating rod 2 15. The synchronous wheel 12 and the synchronous wheel 2 14 are fixedly connected to the outer wall of the rotating rod 2 15. The outer walls are rotatably connected to the inner wall of the door frame 1. A camera 4 for facial recognition, a digital button 6 for entering a digital password, and a fingerprint recognition element 7 for identifying fingerprints are provided on the top side of the front end of the all-in-one machine 3. A baffle 22 is fixedly connected to the bottom end of the door frame 1. The front ends of the two door panels 19 are both arranged at the rear end of the baffle 22. A display screen 5 is fixedly connected to the front end of the all-in-one machine 3. Door-closing buttons 23 are provided at the rear end of the control device 2 and the front end of the all-in-one machine 3. The control device 2 controls the start and stop of the motor 8 and the forward and reverse rotation of its driving end through wireless data transmission.

[0036] Specifically, the user can initiate identity authentication through the camera 4, digital button 6 or fingerprint recognition element 7. The biometric data or password information is transmitted wirelessly to the main control chip of the control device 2, and is compared with the preset database after being processed by the encryption algorithm. After the verification is passed, the main control chip sends a forward rotation instruction to the motor 8 via Bluetooth. When closing the door, the user presses the door closing button 23 on the all-in-one machine 3 or the control device 2. The main control chip controls the motor 8 to reverse and rotate the two door panels 19 toward each other through the same transmission path. The baffle 22 at the bottom of the door frame limits the displacement of the front end of the door panel to prevent excessive opening and closing. The control device 2 has a built-in main control chip, which is responsible for receiving identity authentication data, performing encryption comparison, and sending motor control instructions. It is linked to the motor 8 through wireless communication and integrates the door closing button 23 to control the door closing operation. The display 5 displays operation instructions, error prompts and system status to improve the user experience. 9 and the worm wheel 10 form a worm gear transmission mechanism, which converts the high-speed rotation of the motor 8 into a low-speed, high-torque rotation of the rotating rod 11. At the same time, the self-locking characteristics of the worm gear are used to prevent the door panel from accidentally moving due to external force when it is stationary, thereby improving safety. The synchronous wheel 12 is fixed to the outer wall of the rotating rod 11, and is linked to the synchronous wheel 2 14 through the synchronous belt 13 to achieve the synchronous rotation of the rotating rod 11 and the rotating rod 2 15, ensuring the coordinated movement of the two door panels. The gear 16 is fixed to the outer wall of the rotating rod 2 15 and meshes with the gear 2 17 to convert the rotation of the rotating rod 2 15 into the reverse rotation of the rotating rod 3 18, thereby realizing the mechanical reversal of the relative motion of the two door panels.

[0037] An intelligent identification system for intelligently identifying a door includes the following steps:

[0038] Step 1: The user can authenticate their identity through any of the camera 4, digital button 6 and fingerprint recognition element 7;

[0039] Step 2: The identification data is transmitted to the main control chip in the control device 2 and compared with the preset database through the encryption algorithm for verification;

[0040] Step 3: After the verification is passed, the main control chip sends a command to the motor 8 via Bluetooth to control the forward rotation of the motor 8, so that the two door panels 19 rotate and open.

[0041] In step 1, the user's facial image can be collected through the camera 4 for identity authentication, a preset digital password can be entered through the digital button 6 for identity authentication, and fingerprint information can be collected by placing a finger on the fingerprint identification element 7 for identity authentication.

[0042] In step 2, the collected biometric data or password information is transmitted wirelessly to the main control chip in the control device 2. The main control chip encrypts the input data to prevent data leakage, and then compares the encrypted data with the authorization data in the preset database. If the data matches successfully, a pass signal is generated. If the data does not match, a verification failure signal is generated.

[0043] In step three, after the verification is passed, the main control chip sends a control instruction to the motor 8 through the Bluetooth protocol. The driving end of the motor 8 drives the worm 9 to rotate, and the worm 9 engages with the worm wheel 10, driving the rotating rod 11 to rotate. The synchronous wheel 12 on the outer wall of the rotating rod 11 drives the synchronous wheel 2 14 and the rotating rod 2 15 to rotate through the synchronous belt 13. The gear 16 on the outer wall of the rotating rod 2 15 engages with the gear 2 17, driving the rotating rod 3 18 to rotate in the opposite direction, driving the two door panels to rotate relative to each other and open and close.
