s1: and (3) binding for the first time, identifying and storing lockset information of the lockset by the central control mobile phone, and identifying and storing mobile phone information of the central control mobile phone by the lockset. Before the lock is used for the first time, the central control mobile phone which needs to be unlocked is bound with the lock for the first time, so that the lock can be unlocked only by the bound central control mobile phone in the later unlocking process, other mobile phones are prevented from unlocking the lock at will, and the safety of the lock is primarily guaranteed.

The primary binding process is that communication interconnection is established between a Bluetooth module of the central control mobile phone and a Bluetooth module of the lock, the central control mobile phone can acquire and store lock information in a mode of scanning a two-dimensional code of the lock, and the lock information contained in the two-dimensional code is a MAC address of the lock and a UUID of Bluetooth service. The two-dimensional code needs to be scanned in the process of binding each time of the central control mobile phone, and the central control mobile phone which is bound can prompt the information of the central control mobile phone which is already bound, and the first binding of the central control mobile phone and the lockset can prompt that the central control mobile phone is used for the first time or whether a user exists. Therefore, the lockset can not be bound in advance by anyone or other mobile phone information can be prerecorded in the middle link.

S2: after the binding of the central control mobile phone and the lock is completed, the lock and the central control mobile phone perform data interaction, and the lock can be safely unlocked by using the bound central control mobile phone. When the lock is ready to be unlocked, the central control mobile phone independently generates an unlocking password by using the mobile phone information and the stored lock information, and after the lock responds to an unlocking instruction, the lock independently generates an in-lock password by using the lock information and the stored mobile phone information. However, the unlocking password and the password in the lock adopt the same algorithm, the unlocking APP and the lock do not need to be connected to a network for networking, a third party platform is not needed to generate the unlocking password, the unlocking password is issued to the lock and the mobile phone of the user through the network, and the unlocking process is not limited by the constraint of remote control of a technical provider. Therefore, the whole process is initiated and used by an actual user, a third party platform and network participation are not needed, the safety and reliability of the lockset are ensured, and the cost of the user is reduced.

S3: and the password verification is carried out, an unlocking password generated by the central control mobile phone is sent to the mobile phone of the user, and then the user inputs the unlocking password into the lockset, and the lockset compares and verifies the input unlocking password with the password in the lockset.

S4: and (3) feeding back a verification result, when the unlocking password input in the step (S3) is the same as the in-lock password, the lock is opened, and if the unlocking password input is different from the in-lock password, the lock is regarded as an invalid unlocking password, and the lock is continuously closed.

According to the lock disclosed by the invention, the unlocking password and the password in the lock are generated by independent calculation, the central control mobile phone and the lock do not need to be connected to a network for networking, and the temporary password is not required to be generated and issued by a cloud service platform and stored on the lock and issued on the central control mobile phone, so that the whole process is initiated and used by an actual user, the participation of a third party platform and a network is not required, the safety and the reliability of the intelligent lock are ensured, the personal safety and the property safety of a user are further ensured, and the benefit of the user is ensured.

Further, when unlocking is needed, the processor chip C01 controls the motor to rotate through the motor interface C05 to unlock. The power supply and door magnet interface C07 includes a power supply interface, i.e., a positive terminal and a negative terminal of a dc power supply, through which a battery can be connected, and includes two connection ports, by which whether the door magnet belongs to a closed state or an open state is sensed, and when the processor chip C01 is not controlling the motor to unlock through the motor interface C05, if the processor chip C01 detects that the door magnet is in the open state from the door magnet interface C07, it indicates that the key cylinder assembly may be in an illegally pried state, thereby controlling the speaker to emit an alarm sound.

Preferably, as shown in fig. 10, the communication module is in communication interconnection with a remote control terminal and is further electrically connected with the control module, so as to realize remote control of the lock. The communication module comprises a communication circuit board T00, a wireless communication chip T01 arranged on the communication circuit board T00, a SIM card seat T02 electrically connected with the wireless communication chip T01, a communication interface and an antenna feeder socket T04, wherein the communication interface is correspondingly connected to the control module through a connecting wire.

The wireless communication chip T01 is also electrically connected with a 5-core communication interface T03. The 5-core communication interface T03 is correspondingly connected to a corresponding 5-core communication interface C04 on the control module through 5 connecting wires. Preferably, the wireless communication chip T01 is an NB-IoT module BC28, and the BC28 is encapsulated by LCC, so that the mobile communication terminal has the GSM/GPRS function in mobile communication, and can be rapidly and flexibly switched from a traditional 2G network to an NB-IoT network. Of course, the wireless communication chip T01 also includes 4G and 5G wireless communication dedicated modules. In addition, the module has larger advantages in size, and an OTDOA positioning function is added.

Further, the control module is further provided with a sensor interface, and the sensor interface is used for being connected with various sensors arranged in the box-type distribution network cabinet, for example, a temperature sensor, a humidity sensor, a smoke sensor, a water touch sensor and the like are arranged in the box-type distribution network cabinet, when data monitored by the sensors can be transmitted to the control module through the sensor interface, the control module can be further transmitted to a remote monitoring terminal through the communication module, and therefore monitoring on the internal working state and the running environment of the box-type distribution network cabinet can be obtained.
