Description

Technical Field

[0001] The present invention relates to the technical field of smart locks, and in particular to a smart lock control method and a smart lock control system. Background Art

[0002] With the rapid development of modern technology and the continuous improvement of people's living standards, the concept of smart home has gradually gained popularity. As an important part of smart home, smart locks are favored by more and more users due to their convenience and security. Traditional mechanical locks can no longer meet the dual needs of modern people for convenience and security due to their cumbersome operation and low security. Therefore, smart locks came into being and quickly occupied the market.

[0003] Smart locks are locks that use high-tech means such as biometrics, wireless communication, and encryption algorithms to unlock, lock, and monitor security. Compared with traditional mechanical locks, smart locks have the advantages of easy operation, diverse unlocking methods, and high security. Currently, smart locks on the market mainly use fingerprint recognition, password input, Bluetooth recognition, NFC (near field communication) and other technical means to achieve unlocking operations. However, the existing smart lock system still has some problems and challenges, which are specifically reflected in the following aspects:

[0004] Security issues of a single authentication method: Most existing smart lock systems use a single user identity authentication method, such as fingerprint, password or Bluetooth authentication. This single authentication method has security risks to a certain extent. For example, although fingerprint recognition is convenient, the advancement of fingerprint film replication technology has challenged the security of fingerprint recognition; password authentication has the risk of being peeped and cracked; although Bluetooth authentication is easy to use, its transmission process may be monitored or attacked. These problems make it difficult to fully guarantee the security of smart locks.

[0005] Wireless communication stability issues: Smart locks rely on wireless communication modules (such as Wi-Fi, Bluetooth, NFC, etc.) to receive and execute the user's unlocking instructions. However, in actual applications, wireless communications are easily affected by signal interference and environmental factors, resulting in unlocking failures or misoperations. For example, in an environment with weak signals or strong interference, the transmission efficiency of Wi-Fi and Bluetooth will drop significantly, affecting the user experience. In addition, data is vulnerable to hacker attacks during transmission, and there is a risk of information being stolen or tampered with.

[0006] Energy management challenges: Smart locks are usually powered by batteries, so energy management becomes a key issue. How to extend the battery life while ensuring the efficient operation of smart locks is an important challenge that smart lock technology needs to solve. Some existing smart lock products have short battery life due to improper energy management, and users need to frequently replace batteries, resulting in a poor user experience.
