The process can be further refined into the following steps:

s1: and (4) binding for the first time, identifying and storing the lock information of the lock by the central control mobile phone, and identifying and storing the mobile phone information of the central control mobile phone by the lock. Before the lockset is used for the first time, the central control mobile phone needing to be unlocked is firstly bound with the lockset, so that the lockset can be unlocked only by the bound central control mobile phone in the later unlocking process, other mobile phones are prevented from unlocking the lockset at will, and the safety of the lockset is preliminarily ensured.

The first binding process is that the Bluetooth module of the central control mobile phone and the Bluetooth module of the lock are communicated and interconnected, the central control mobile phone can selectively acquire and store lock information in a mode of scanning a two-dimensional code of the lock, and the lock information included in the two-dimensional code is an MAC address of the lock and a UUID of Bluetooth service. The two-dimensional code needs to be scanned in the binding process of the central control mobile phone every time, the central control mobile phone binding the central control mobile phone can prompt the information of the bound central control mobile phone every time the central control mobile phone is bound, and the central control mobile phone and the lockset are bound for the first time to prompt whether the central control mobile phone is used for the first time or whether a user exists. Therefore, the lockset can not be bound by anyone in advance or other mobile phone information can not be prerecorded in the middle link.

S2: and generating a password, and after the central control mobile phone and the lock are bound, performing data interaction on the lock and the central control mobile phone, so that the bound central control mobile phone can be used for safely unlocking the lock. When the central control mobile phone is ready to unlock, 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 are the same, 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 a user mobile phone through the network, and the unlocking process is not limited by the restriction 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 the reliability of the lockset are guaranteed, and meanwhile, the cost of a user is reduced.

S3: and password verification, namely sending the unlocking password generated by the central control mobile phone to a required user mobile phone, inputting the unlocking password into a lockset by a user, and comparing and verifying the input unlocking password with the password in the lock by the lockset.

S4: and (4) feeding back a verification result, if the unlocking password input in the step (S3) is the same as the password in the lock, the lock is opened if the unlocking password is considered to be a valid unlocking password, and if the unlocking password input in the step (S3) is different from the password in the lock, the lock is continuously closed if the unlocking password is considered to be an invalid unlocking password.
