[0050] Reference Fig. 9An embodiment of the present invention provides an unlocking method of an NFC lock, which is applied to an NFC lock. The NFC lock includes a locking module 100 and an unlocking module 200. The locking module 100 and the unlocking module 200 are electrically connected. The locking module 100 is provided with a power supply module 110, a control module 120 and a first NFC interface 130. The control module 120 is electrically connected to the power supply module 110 and the first NFC interface 130 respectively. The unlocking module 200 is provided with a second NFC interface 210. The first NFC interface 130 and the second NFC interface 210 are connected through coil coupling.

[0051] It should be noted that the locking module 100 is internally provided with a power supply module 110, which can be a battery, and the control module 120 is a low-power MCU. A SOC chip with Bluetooth, Zigbee or 2.4G can be selected according to actual implementation requirements, and a switch circuit with hardware startup and software shutdown is adopted. The NFC communication interface is used as a trigger source and data interaction, and the unlocking module 200 also has an NFC communication function. When the unlocking module 200 is attached to the surface of the locking module 100, the first NFC interface 130 and the second NFC interface 210 are coupled through a coil, and the NFC interface circuit inside the locking module 100 outputs a trigger signal to the control module 120, so that the locking module 100 is powered on, and data interaction is performed through the first NFC interface 130 and the second NFC interface 210 to complete identity authentication, send unlocking operation instructions, and transmit information such as the lock status.

[0052] It should be noted that the Bluetooth locks, Zigbee locks, 2.4G locks, etc. in the prior art can establish a connection within a range of 10 meters or even farther to exchange data and achieve unlocking. However, in this embodiment, the first NFC interface 130 and the second NFC interface 210 are used for data exchange, which is a near-field coupling method. The coupling distance is generally not more than 5 cm, and the coupling parts need to be directly opposite. Therefore, it can avoid the situation where the unlocking device searches for multiple locks at the same time, thereby avoiding the need to select which lock to connect. In addition, the energy generated by the coupling between the first NFC interface 130 and the second NFC interface 210 is small, and the instantaneous power is not enough to drive the unlocking module 200 to unlock the locking module 100. Therefore, the locking module 100 has a built-in power supply module 110, and the first NFC interface 130 and the second NFC interface 210 are only used as trigger sources and data exchange channels.

[0053] The control method of the embodiment of the present invention is further described below based on the accompanying drawings.

[0054] Reference Figure 1 , Figure 1A flowchart of an unlocking method of an NFC lock provided by an embodiment of the present invention, the unlocking method of the NFC lock includes but is not limited to the following steps:

[0055] Step S11, moving the second NFC interface 210 into the sensing range of the first NFC interface 130, so that the first NFC interface 130 sends a trigger signal to the power supply module 110;

[0056] It should be noted that the first NFC interface 130 and the second NFC interface 210 transmit information through magnetic field coupling, and the unlocking module 200 and the locking module 100 are in passive communication mode. In the passive communication mode, the locking module 100 needs to be powered, and the unlocking module 200 does not need to be powered. When the second NFC interface 210 moves into the sensing range of the first NFC interface 130, the second NFC interface 210 will send a radio signal as an active device to form an electromagnetic field. As a passive device, the second NFC interface 210 obtains energy from the electromagnetic field after sensing the electromagnetic field. At the same time, the second NFC interface 210 loads the trigger signal onto the electromagnetic field and transmits it to the first NFC interface 130. After receiving the trigger signal, the first NFC interface 130 will convert the trigger signal into an electrical signal, thereby triggering the power supply module 110 to work.

[0057] Step S12, the power supply module 110 powers on the control module 120 according to the trigger signal, and performs an initialization operation on the control module 120;

[0058] It should be noted that when the power supply door powers on the control module 120 according to the trigger signal, the control module 120 is powered on again from the power-off state and enters the working state, ensuring that when the locking module 100 receives subsequent operation instructions, it can respond to the operation instructions quickly, thereby improving the unlocking efficiency.

[0059] Step S13, confirming the first NFC data of the locking module 100 and the second NFC data of the unlocking module 200, and the control module 120 performs data interaction on the first NFC data and the second NFC data to obtain the identity authentication information of the unlocking module 200;

[0060] It should be noted that by comparing the first NFC data of the locking module 100 and the second NFC data of the unlocking module 200, the control module 120 verifies the legitimacy of the unlocking module 200, and only when the first NFC data and the second NFC data match, the locking module 100 will perform the unlocking operation through the unlocking module 200. Furthermore, the NFC lock allows the user to unlock the lock by simply approaching, without inserting a key or entering a password, and the data interaction and identity verification process are usually completed in a very short time, further improving the convenience of the NFC lock while ensuring the security of the NFC lock.

[0061] Step S14, the control module 120 verifies the unlocking module 200 according to the identity authentication information, so that the unlocking module 200 sends an operation instruction to the control module 120;

[0062] It should be noted that the control module 120 verifies the unlocking module 200 according to the identity verification information. By verifying the NFC data of the unlocking module 200 and its identity verification information, the control module 120 can ensure that only the unlocking module 200 that has passed the identity verification can send an operation instruction.

[0063] In step S15 , the locking module 100 performs an unlocking operation or a locking operation according to the operation instruction. When the locking module 100 completes the operation instruction, the power supply module 110 stops supplying power to the control module 120 .

[0064] It should be noted that the power supply module 110 in this embodiment only supplies power to the power supply module 110 and the motor during the unlocking operation, and the first NFC interface 130 and the second NFC interface 210 are powered by coil coupling. In addition, since the power supply module 110 does not supply power to the outside, the power supply is stopped immediately after the locking module 100 completes the unlocking or locking operation, which further reduces the power consumption of the NFC lock and improves the battery life and long-term standby reliability of the NFC lock.

[0065] It should be noted that the locking module 100 of the present embodiment has a built-in power supply module 110. The locking module 100 is powered off and shut down when it is not working. The locking module 100 is triggered to start up by the unlocking module 200. A trigger signal is generated between the first NFC interface 130 and the second NFC interface 210 through coil coupling, so that the locking module 100 is powered on and started up according to the trigger signal. After the locking module 100 is powered on and started up, data exchange and identity confirmation are performed through the first NFC interface 130 and the second NFC interface 210, thereby completing the unlocking operation of the locking module 100 and the status collection and transmission of the NFC lock. The locking module 100 can be awakened by simply bringing the unlocking module 200 close to the locking module 100, which can avoid the inability to determine which lock to connect when multiple locks are working at the same time, and can also effectively reduce the NFC lock identity recognition and unlocking operation time.

[0066] In addition, in one embodiment, referring to Figure 2 ,exist Figure 1 After step S15 in the illustrated embodiment, the following steps are also included but not limited to:

[0067] Step S21, the control module 120 obtains the feedback status information of the NFC lock, and the control module 120 confirms whether the unlocking module 200 sends an additional operation instruction different from the unlocking operation or the locking operation according to the feedback status information;

[0068] In step S22 , when the unlocking module 200 sends the additional operation instruction to the locking module 100 , the locking module 100 executes the additional operation instruction.

[0069] It should be noted that the control module 120 obtains the feedback status information of the locking module 100 in real time by interacting with the NFC lock. This information includes but is not limited to the current state of the lock (such as unlocked, locked, abnormal state, etc.), operation time, number of operations and other key data. The lock executes the status update instruction so that the NFC module can update the status information of the lock in real time and feedback it to the user. Alternatively, after the control module 120 obtains the feedback status information of the NFC lock, the locking module 100 immediately re-unlocks or locks the lock, thereby further improving the unlocking speed of the NFC lock.

[0070] In addition, in one embodiment, referring to Figure 3 ,exist Figure 1 Step S11 of the illustrated embodiment also includes but is not limited to the following steps:

[0071] Step S31, when the unlocking module 200 does not send an additional operation instruction to the locking module 100, the control module 120 confirms whether the power supply module 110 reaches a preset delay time;

[0072] Step S32, when the power supply module 110 reaches the preset delay time, the control module 120 stops supplying power;

[0073] Step S33: when the power supply module 110 does not reach the preset delay time, reconfirm the feedback status information of the NFC lock.

[0074] It should be noted that, by setting a preset delay time and intelligently controlling the power supply status of the power supply module 110, the NFC lock can extend the service life of the power supply module 110 as much as possible while meeting normal working requirements, thereby reducing the maintenance cost of the NFC lock; when the power supply module 110 reaches the preset delay time, the control module 120 reconfirms the feedback status information of the NFC lock, and by reconfirming the status information of the NFC lock in real time, the control module 120 can quickly obtain the abnormal status of the lock, thereby making a timely response, avoiding the situation where the NFC lock cannot be unlocked or locked, and further improving the safety and reliability of the NFC lock.

[0075] In addition, in one embodiment, referring to Figure 4 ,exist Figure 1 Step S11 of the illustrated embodiment also includes but is not limited to the following steps:

[0076] Step S41, turning on the first MOS tube D1, the power supply module 110 inputs an initial voltage to the first switch tube Q1, so as to power on the control module 120 and perform an initialization operation;

[0077] In step S42 , the control module 120 turns on the second switch tube Q2 to keep the first switch tube Q1 turned on continuously.

[0078] It should be noted that by turning on the first MOS tube D1, the power supply module 110 can quickly provide the control module 120 with the initial voltage required for unlocking and locking operations, thereby accelerating the startup process of the control module 120. The continuous conduction of the first switch tube Q1 ensures that the control module 120 obtains a stable power supply during initialization and subsequent operations. Thereby ensuring the normal operation and accurate unlocking of the control module 120. Furthermore, the control module 120 maintains the continuous conduction state of the first switch tube Q1 by turning on the second switch tube Q2, while ensuring the necessary functions of the locking module 100, reducing unnecessary energy loss, thereby extending the service life of the NFC lock. The NFC lock uses an automated control process so that the user can unlock the NFC lock without performing complicated operations. It improves the user's convenience and reduces the risk of unlocking failure due to improper operation.

[0079] In addition, in one embodiment, referring to Figure 5 ,exist Figure 1Step S11 of the illustrated embodiment also includes but is not limited to the following steps:

[0080] Step S51, confirming the first ID code of the locking module 100 and the second ID code of the unlocking module 200;

[0081] Step S52, when the first NFC interface 130 is connected to the second NFC interface 210, the control module 120 reads the second ID code and compares the second ID code with the first ID code;

[0082] Step S53 , when the first ID code matches the second ID code, the unlocking module 200 sends an operation instruction to the locking module 100 .

[0083] It should be noted that by comparing the first ID code of the locking module 100 and the second ID code of the unlocking module 200, it can be ensured that only the unlocking module 200 with the correct ID code can unlock the corresponding locking module 100, thereby enhancing the security of the NFC lock and preventing the locking module 100 from being accessed and unlocked without authorization. Further, the ID code matching process ensures that only the unlocking module 200 that matches the locking module 100 can send an operation instruction to the locking module 100. This avoids the situation where the NFC lock is mis-locked due to misoperation or misidentification. In addition, the user does not need to perform complex operations or enter cumbersome passwords, and only needs to bring the second NFC interface 210 of the unlocking module 200 with the correct ID code close to the second NFC interface 210 of the locking module 100 to complete the unlocking. This simplifies the operation process of the NFC lock, simplifies the unlocking time of the NFC lock, and improves the user's convenience.

[0084] In addition, in one embodiment, referring to Figure 6 ,exist Figure 1 Step S11 of the illustrated embodiment also includes but is not limited to the following steps:

[0085] Step S61, confirming the first communication protocol preset in the unlocking module 200 and the second communication protocol preset in the locking module 100;

[0086] Step S62 , when the first communication protocol and the second communication protocol match, the unlocking module 200 is authorized so that the unlocking module 200 performs an unlocking operation on the locking module 100 .

[0087] It should be noted that the unlocking module 200 and the locking module 100 perform data exchange through the first communication protocol and the second communication protocol, so it is possible to prevent the unauthorized unlocking module 200 from performing unlocking operations on the locking module 100 through NFC, and the above logic can ensure the security of two-way identity authentication. By confirming and matching the first communication protocol and the second communication protocol between the unlocking module 200 and the locking module 100, it is ensured that the unlocking module 200 and the locking module 100 can communicate stably and effectively. Thereby enhancing the communication compatibility of the NFC lock, and avoiding the occurrence of unlocking failure or erroneous unlocking caused by mismatching of the communication protocols. Only when the first communication protocol and the second communication protocol match, the unlocking module 200 will be authorized to unlock the locking module 100, thereby improving the accuracy of unlocking. This embodiment effectively simplifies the configuration process of the NFC lock system by presetting the communication protocol and performing authorization when matching. The user does not need to perform complex settings or adjustments, and only needs to ensure that the communication protocols of the unlocking module 200 and the locking module 100 match to realize the unlocking function of the NFC lock.

[0088] In addition, in one embodiment, referring to Figure 7 ,exist Figure 1 Step S11 of the illustrated embodiment also includes but is not limited to the following steps:

[0089] Step S71, when the unlocking module 200 passes the verification, the unlocking module 200 sends an operation instruction to the locking module 100;

[0090] Step S72 , when the unlocking module 200 fails the verification, the unlocking module 200 is disconnected from the locking module 100 .

[0091] It should be noted that, through the verification mechanism, it is ensured that only the legitimate unlocking module 200 can send an operation instruction to the locking module 100, thereby unlocking the NFC lock. The security of the NFC lock is enhanced to prevent unauthorized access and unlocking. When the unlocking module 200 fails to pass the verification, the locking module 100 will automatically disconnect the control module 120 from the power supply module 110, avoiding the lock being mislocked due to misoperation or misidentification.
