s2: when a person is judged, the front distance sensor 3 informs the control module to open the face recognition module 2 (whether the face recognition module is used or not can be selected according to setting, and when a plurality of people wear the mask in winter, if the recognition accuracy is reduced, the face recognition module can be selected to be cancelled);

s3: when the face recognition module 2 recognizes that the user in front is an authenticated user, it notifies the control module to open the fingerprint recognition module 5, and the protective cover 4 attached to the fingerprint recognition module 5 moves upward, at which time the slide motor 15 drives the slider 402 to move upward along the slide bar 14 (if step S2 is cancelled, this step is started after step S1);

s4: the user touches the sterilized fingerprint identification module 5, when the fingerprint identification module 5 identifies that the user in front of the door lock is an authenticated user, the door lock is opened, and at the moment, the sliding motor 15 drives the sliding block 402 to move downwards along the sliding rod 14 for resetting;

s5: when the user enters the room and the door is closed, the rear distance sensor 10 senses that the user enters and informs the control module to close the door;

s6: when the door is closed, the control module controls the protective cover 4 to move downwards, the fingerprint identification module 5 is covered by the protective cover 4, and the fingerprint identification module 5 is erased and sterilized to wait for the next user to use.

S7: if the first user is authenticated successfully and the door lock is opened, the rear distance sensor 10 does not recognize that the user enters within the set time, and the front distance sensor 3 cannot recognize that a person approaches, the control module is informed to close the door lock.

S8: when the rear distance sensor recognizes that the user approaches and the front distance sensor does not recognize that the user approaches, it is determined that the user in the room needs to leave, and the control module directly opens the door lock without authentication.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
