Abstract

The invention relates to the technical field of door locks and particularly relates to an NFC (Near Field Communication) door lock system and an unlocking method thereof. The NFC door lock system comprises an NFC label and a door lock, wherein the NFC label stores a bluetooth pairing instruction and an unlocking instruction which can be read by an NFC terminal; the door lock is mounted on the inner side of a door; the door lock comprises a bluetooth module; the bluetooth module is connected with a clutch driving mechanism of the door lock, is used for receiving the bluetooth pairing instruction and the unlocking instruction which are sent by the NFC terminal, is paired with the NFC terminal according to the bluetooth pairing instruction, is used for controlling the clutch driving mechanism to unlock according to the unlocking instruction after the pairing is successful, and is paired with bluetooth of the NFC terminal after the unlocking is canceled. With the adoption of the manner, the door lock is not arranged on the outer side of the door and the difficulty of carrying out illegal technical unlocking on the outer side of the door is greatly lowered; the safety of the door lock is improved.

Description

technical field [0001] The invention relates to the technical field of door locks, in particular to an NFC door lock system and an unlocking method thereof. Background technique [0002] Because the existing door lock has an unlocking mechanism on the outside of the door, there is always the possibility of being unlocked illegally. However, if the door lock is set on the inside of the door, it can be effectively unlocked by sending a wireless unlock command to the door lock on the outside of the door. solve this problem. NFC (Near Field Sensing) technology is a short-range wireless communication technology with short communication distance, low transmission power and natural security, which can be applied in the field of door locks. However, due to the short distance of NFC communication and low transmission power, metal materials have a significant impact on the shielding of NFC signals, resulting in the door lock on the inside of the door being unable to receive the unloc...
