Through the bluetooth module C02, the processor chip C01 can receive bluetooth information for unlocking transmitted from an external device (e.g., a mobile phone), and when the unlocking password information included in the bluetooth information is the same as the password in the lock, the lock can be unlocked, otherwise, the lock cannot be unlocked. The password in the lock can receive password setting information from the communication module through the communication interface C04, so that the password in the lock and the unlocking password can be dynamically updated, when a user needs to unlock the lock, a request can be sent to the control center through the mobile phone, when the control center identifies that the mobile phone is a legal user, the password can be generated and respectively sent to the mobile phone of the user and the communication module, the communication module inputs the password into the processor chip of the control module to be used as the password in the lock, the mobile phone of the user inputs the password into the processor chip of the control module to be used as the unlocking password in a Bluetooth mode, and when the password in the lock and the unlocking password are compared and verified through the processor chip to be consistent, the unlocking can be realized.

Further preferably, password unlocking can be realized without a control center, so that the unlocking safety is further enhanced. Here, install the APP of unblanking in the well accuse cell-phone, this APP of unblanking can be according to predetermineeing algorithm developments and generate the password of unblanking, when the user unblanks to well accuse cell-phone request, well accuse cell-phone can be according to user's needs with unblanking the password and send user's cell-phone, and the inside control module of this tool to lock also through predetermineeing algorithm developments generation in-lock password, well accuse cell-phone and this tool to lock have carried out binding setting in advance, unblanking password and in-lock password are synchronous dynamic change, but the two is unanimous again, therefore when user's cell-phone input is unblanked the password, with the in-lock password that produces inside this tool to lock have the uniformity, consequently can realize that the dynamic password unblanks, and this kind of mode need.

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.
