In other embodiments, the rfid device may also be an electronic device integrated with a rfid coil and installed in a decorative item, such as a mailbox or a flower basket, hung on a wall in front of a door.
S12: and judging whether the radio frequency identification information is authorized information.
Specifically, after the smart lock acquires corresponding radio frequency identification information through a radio frequency identification device laid on the ground, it is further determined whether the acquired radio frequency identification information is authorized information, for example, whether the acquired radio frequency identification information includes unlocking encryption data matched with the smart lock is determined to determine whether the radio frequency identification information is authorized information.
Wherein if the rfid information is authorized information, S13 is performed, and if the rfid information is not authorized information, S14 is performed.
S13: the door lock is unlocked.
When the obtained radio frequency identification information is determined to be authorized information, the intelligent lock opens the corresponding door lock, for example, a power supply of a driving motor corresponding to the intelligent lock cylinder is switched on, so that the driving motor rotates forwards and opens the door lock, and therefore the intelligent lock can be unlocked efficiently and conveniently without manual operation, and great convenience is brought to a user.
S14: the door lock continues to be held closed.

and the lock cylinder driver is connected with the power circuit and the master control circuit and used for receiving an unlocking control signal sent by the master control circuit when the radio frequency identification information is determined to be authorized information so as to drive the lock cylinder connected to the lock cylinder driver to act and open the door lock.
8. The smart lock of claim 7,
the intelligent lock further comprises a radio frequency identifier, wherein the radio frequency identifier is connected with the power supply circuit and the master control circuit and used for detecting whether an authorization card exists in a radio frequency identification area of the radio frequency identifier or not, so that when the authorization card exists in the radio frequency identification area of the radio frequency identifier, an authorization allowing signal is sent to the master control circuit, and the master control circuit writes preset radio frequency identification information into a target NFC label placed in the radio frequency identification area of the radio frequency identifier.
9. The smart lock of claim 7,
the intelligent lock further comprises an alarm indicating circuit, wherein the alarm indicating circuit is connected with the power circuit and the main control circuit and is used for sending an alarm indication when receiving an alarm control signal sent by the main control circuit when the main control circuit detects that the corresponding door lock is not closed and exceeds a set time threshold.
10. A radio frequency identification device, wherein the radio frequency identification device is laid on the ground, the radio frequency identification device comprising:
a structural shell;
the power supply circuit is arranged on the structural shell and used for providing a working power supply signal;
the radio frequency identification coil is arranged on the structural shell, connected with the power circuit and externally connected with an intelligent lock, and is used for acquiring corresponding radio frequency identification information so as to send the radio frequency identification information to the intelligent lock, so that the intelligent lock judges whether the radio frequency identification information is authorized information or not, a door lock is opened when the radio frequency identification information is determined to be the authorized information, and the door lock is continuously kept closed when the radio frequency identification information is not the authorized information.
