[0002] An intelligent lock, as an execution component of an access control system different from a traditional mechanical lock, has received extensive attention and application due to its intelligence, security, and convenience. It not only has the basic functions of a traditional lock but also realizes a more convenient, secure, and intelligent door-opening method by integrating advanced technologies such as electronics, the Internet of Things, and biometric recognition. The intelligent lock supports multiple door-opening methods, such as fingerprint, password, mobile APP remote unlocking, Bluetooth key, etc., eliminating the trouble of carrying keys and avoiding the embarrassing situation of forgetting to bring keys. The application scenarios of intelligent locks are very extensive, including residential houses, apartments, hotels, offices, schools, hospitals, and other places. With the continuous development and popularization of the Internet of Things technology, the application scope of intelligent locks will continue to expand.
