In addition, the widespread use of electronic locks in public places such as hotels, schools, and medical institutions has also greatly improved the security and management efficiency of these places.

[0003] Existing electronic locks mainly rely on biometric technology (such as fingerprint recognition, iris recognition, facial recognition, etc.), password recognition or radio frequency identification (RFID) to achieve access control. Its basic structure usually includes lock body, control circuit, recognition module and power module. The recognition module is responsible for receiving and verifying the user's identity information, and the control circuit controls the switch of the lock body according to the verification result. In the face recognition electronic lock, the recognition module usually includes a high-definition camera and a high-performance image processing unit. The camera is responsible for capturing the user's facial image, and the image processing unit is responsible for comparing the captured image with the pre-stored facial feature template to verify the user's identity.

[0004] However, although the existing electronic locks have significant advantages over traditional mechanical locks in terms of security and convenience, there are still some defects and shortcomings. In actual use, the wireless connection of the camera module is prone to low recognition accuracy, and the user may make multiple attempts, or the user's face may be blocked or stained and cannot be recognized. The existing electronic locks lack a display device, which reduces the user's experience. The installation structure of the control end shell of the existing electronic lock is relatively complicated, and usually requires the use of tools for installation and disassembly, which affects the installation efficiency and use effect.
