The first control module 13 is powered by the wireless power receiving module 10, and the wireless power receiving module 10 also supplies power to the first communication module 12 and the driving device 14. Under the condition that the wireless power supply receiving module 10 is powered on, the first communication module 12 and the first control module 13 are both in working states and are electrically connected with each other, and data information can be transmitted. The first communication module 12 is configured to receive the verification information sent by the second communication module 21, and then send the verification information to the first control module 13, and the first control module 13 checks the verification information with a plurality of pieces of verification information pre-stored therein, and if the information matches, for example, the received verification information exists in the first control module 13, the first control module 13 sends an unlocking instruction/a locking instruction to the driving device 14, so as to drive the lock tongue of the mechanical lock body 11 to retract/extend.
It should be noted that the first control module 13 is provided with a command transmission program configured to transmit an unlocking command/locking command to the drive device 14 after the verification information received by the first communication module 12 matches any one of the verification information stored in the first control module 13. Specifically, the program is also set such that the unlock command and the lock close command are issued alternately. That is, if the command transmitted to the driving device 14 at the previous time is an unlocking command, the command transmitted to the driving device 14 at the subsequent time is a locking command; if the command transmitted to the drive device 14 at the previous time is the lock-off command, the command transmitted to the drive device 14 at the subsequent time is the lock-on command.
According to the method for unlocking/locking, a module for monitoring the opening and closing state of the lock body does not need to be arranged on the lock body part, meanwhile, the key part does not need to send an unlocking instruction and a locking instruction to the lock body part, and the key part only needs to send verification information to the lock body part. By adopting the unlocking/locking method, the structure of the passive lock can be simplified, and the manufacturing cost is reduced; meanwhile, the interaction times of wireless information are reduced, for example, the key part sends an unlocking instruction/a locking instruction to the lock body part, the fault rate is reduced, meanwhile, other people can be prevented from directly sending wireless signals including the unlocking instruction/the locking instruction to the lock body part by adopting technical means to a certain extent, and the safety of the lock body is improved.

For example, the second communication module 21 is an IC card or an ID card of ISO/IEC14443 standard protocol, such as an MIFI _ S70 card; the first communication module 12 is provided as a card reading device, such as an FM17522E card reading module. When the second communication module 21 approaches the first communication module 12, the data in the first communication module 12 can be read by the first communication module 12. Alternatively, the second communication module 21 can adopt a 125KHZ or 13.56MHZ smart card, and the first communication module 12 adopts a card reading device corresponding to the second communication module 21, so that the data communication function can be realized. Still alternatively, the first communication module 12 and the second communication module 21 may implement a short-range communication function by using technologies such as bluetooth, NFC, wireless network, and the like.
In the key portion 2: the second control module 23 is connected to the wireless power source transmitting module 20, the second communication module 21 and the fingerprint inputting module 22, and can send instructions and/or data to the latter. Similarly, the second control module 23 may be implemented by a single chip microcomputer, for example, a single chip microcomputer of STM8L051F3 type, which has functions of storage, data processing, etc., and can send instructions and data to the second communication module 21 according to preset logic, control the on/off of the wireless power supply transmitting module 20 according to preset logic, receive fingerprint information collected by the fingerprint input module 22, and check the fingerprint information with prestored fingerprint information. The fingerprint entry module 22 may be implemented using a SA11-a fingerprint module.
A plurality of fingerprint information is prestored in the second control module 23 and used as fingerprint information authorized to unlock or lock, and the second control module 23 can start the wireless power supply transmitting module 20 and the second communication module 21 only when the subsequently input fingerprint information is matched with any fingerprint prestored in the second control module 23.
In this embodiment, the second communication module 21 is pre-stored with authentication information, and after receiving the activation instruction of the second control module 23, the authentication information is sent to the first communication module 12.
In another embodiment, a plurality of verification messages are pre-stored in the second control module 23, and when the second control module 23 sends a start instruction to the second communication module 21 during unlocking/unlocking, the verification messages are sent at the same time, and then the second communication module 21 sends the verification messages to the first communication module 12. When the authentication information is stored in the second control module 23, an input module 24 is also provided in the key part 2, the input module 24 being connected to the second control module 23. The plurality of authentication information stored in the second control module 23 may be configured to match different lock body portions 1, respectively, that is, each authentication information may open or close its corresponding lock body portion 1.
The input module 24 may be, for example, a display screen with a touch function, and the number of the verification information or the verification information stored in the second control module 23 may be input through the input module 24. After entering the authentication information in the input module 24, the authentication information is transmitted to the second control module 23 and, after verification of the entered fingerprint information, is sent to the first communication module 12 via the second communication module 21. After the serial numbers of a plurality of pieces of authentication information stored in the second control module 23 are input in the input module 24, the serial numbers are transmitted to the second control module 23, and after the input fingerprint information passes verification, the second control module 23 sends the authentication information corresponding to the serial numbers to the first communication module 12 through the second communication module 21. By means of this input device, it is possible to achieve that a single key part 2 matches a plurality of lock body parts 1 and that a specific lock body can be opened or closed precisely. In addition, a light or sound prompting device, such as a light emitting diode or a sound, is disposed on the key portion 2, and a light or sound prompting signal is emitted when the fingerprint information collected by the fingerprint input module 22 does not match the pre-stored fingerprint information.
In addition, the key part 2 is provided with an on-off switch, and the key part can be opened or closed before and after unlocking/locking, so that the functions of power supply, identity recognition and the like on the key part 2 can be opened or closed.

Before unlocking/locking, identity verification is firstly needed, whether unlocking/locking personnel are the preset holders of the keys or not is judged, and unlocking/locking behaviors can be carried out only after fingerprint verification is passed. The situation that the key is lost and is picked up by others to unlock is avoided, and the safety of the passive lock is improved.
And step two, the second control module 23 verifies whether the entered fingerprint information of the person who unlocks/locks accords with the fingerprint information prestored in the second control module 23, if not, the unlocking/locking is stopped, if so, the wireless power supply transmitting module 20 is opened to supply power to the lock body part 1, and the second communication module 21 sends verification information to the first communication module 12.
Specifically, the fingerprint information of a plurality of users can be prestored in the second control module 23, and in the using process, the fingerprint information collected by the fingerprint input module 22 conforms to any prestored fingerprint information, so that unlocking/locking can be continuously performed.
Wherein, the second communication module 21 sends the verification information to the first communication module 12 after receiving the instruction of the second control module 23, which is sent if the fingerprint information is verified. The second communication module 21 may send the authentication information stored in itself to the first communication module 12, or send the authentication information transmitted from the second control module 23 to the second communication module 21.
And step three, the first control module 13 checks the verification information received by the first communication module 12 with the verification information prestored in the first control module 13, if the verification information does not conform to the verification information, the unlocking/locking is stopped, and if the verification information conforms to the verification information, an unlocking/locking instruction is sent to the driving device 14 to drive the lock tongue to retract/extend.
Specifically, a plurality of verification information can be prestored in the first control module 13, and can be used for opening/closing the lock body, and different verification information can be sent to different users during use, so that management is facilitated. In the using process, if the verification information received by the first communication module 12 matches any one of the pre-stored verification information, the unlocking/locking can be continued.
After each verification of the authentication information, the first control module 13 sends an unlocking/locking instruction to the driving device 14, specifically, according to a mode of alternately sending an unlocking instruction and a locking instruction, that is, if a previous instruction is an unlocking instruction, a next instruction is a locking instruction.
In addition, when the key part 2 is provided with the input module 24, before entering the fingerprint information of the person who unlocks/locks, the verification information or the number of the verification information prestored in the second control module 23 needs to be input into the input module 24 of the key part 2.
