Two-dimensional code unlocking method and device

The invention provides a two-dimensional code unlocking method and device, and relates to the technical field of intelligent locks. The method is applied to a lock controller. The above lock also comprises a scanning component and an unlocking execution component. The method comprises the following steps that: if the unlocking request of a user is received, controlling the scanning component to execute a two-dimensional code scanning operation to scan a two-dimensional code provided by the user; judging whether the scanned two-dimensional code is legal or not; and if the scanned two-dimensional code is legal, controlling the unlocking execution component to execute an unlocking operation. By use of the method, the two-dimensional code is taken as a key, a door lock serves as a scanning tool for unlocking, and the reliability of the lock can be effectively improved. 本发明提供了一种二维码开锁方法及装置，涉及智能锁具技术领域。该方法应用于锁具的控制器，上述锁具还包括扫描组件和开锁执行组件，该方法包括：如果接收到用户的开锁请求，控制扫描组件执行二维码扫描操作，以扫描用户提供的二维码；判断扫描到的二维码是否合法；如果合法，控制开锁执行组件执行开锁操作。该方法
