it should be emphasized that, after the password input port is opened, the toothed part of the ratchet wheel 9 is in a clamping state with the pawl, at this time, the driving motor 8 will stop driving the ratchet wheel 9 to rotate, so that the password input port is kept in an opened state, a time for a person to input a password is provided, after the time is over, the driving motor 8 drives the ratchet wheel 9 to continue to rotate to complete a circle of rotation, so that, in a later stroke of the rotation of the ratchet wheel 9, the toothed part on the ratchet wheel will be separated from the pawl, and further, the first cylindrical spring 12 rebounds, so that the lifting plate 21 and the sliding cover 7 are lowered and reset, and the password input port is closed again.

Preferably, the pause time (i.e. the time provided for the person to input the password) in the process of driving the ratchet wheel 9 to rotate reversely by the driving motor 8 is 30-40s.

It should be noted that after the comparison result is not matched, the transmission module sends the face information which fails to pass the matching to the remote client (mobile phone APP), so that the user can make a judgment according to the received face information, and a string of passwords is randomly generated at the password input port, and the visitor can open the door by inputting the passwords;

the door-opening password can be acquired through face identification every time, and the passwords used in door opening are different every time, so that double guarantees are effectively realized, and the safety performance of the system can be greatly improved;

after the visitor opens the door, the mobile phone APP of the remote user can automatically skip the monitoring of the house, the broadcasting unit of the house can automatically prompt the visitor to enter a monitoring area, and after the strange visitor (such as a maintenance person, a takeaway or a courier) enters the room, the monitoring device has a certain constraint effect, and avoids causing unnecessary troubles.

The face features extracted from the memory by the comparison module each time comprise mouth, nose, ears, hairstyle, ears, eyes and the like, and when the face features are compared each time, only two features of the face features are in accordance, the comparison result is passed;

certainly, in actual use, a user can change the number of features required to be met in each comparison by himself/herself, so that the safety performance is improved, and part of the face features which are not matched with each other and are acquired by the partial acquisition unit are sent to the memory to be stored, so that automatic supplement of information in the memory is realized, and when the face features are used for changing the shape (for example, changing the hairstyle, wearing a hat or a mask), the comparison module can still obtain an accurate comparison result.

step one, a detection unit detects whether a visitor exists in real time, and when the visitor exists, the detection unit communicates with a lock body movement module;

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
