It should be noted that the mobile terminal may be, but is not limited to, an applet, an app, and the like.
When the user needs to enter the corresponding community, the user mobile terminal can be operated to send the authorized user identification to the management background. For example, a user opens a user mobile terminal, clicks to enter a corresponding applet or APP, the user mobile terminal opens the applet or APP according to an operation instruction of the user, and then sends an authorized user ID to a management background through the applet or APP.
Before this, a user is required to perform registration application and authorization application to obtain an available user ID after authorization, and the specific process includes: the user sends registration information to the management background through the user mobile terminal, the management background completes user registration according to the registration information, and unique authentication information such as a mobile phone number and openid can be bound as a user identifier when the user registers; after the successful registration, the user sends an authorization application to the management background through the user mobile terminal, wherein the authorization application comprises a user identifier and an internal community address for applying authorization; after judging that the user can be authorized, the manager binds the address in the application authorization community and the user identifier through the management background; the manager can increase, modify and remove the binding relationship between more addresses and user identifications in the community through the management background according to the actual situation, and complete the authorization of the user; a user may have multiple authorized intra-community addresses; meanwhile, the management background maintains a corresponding relation list of the intra-community address and the unique device identifier, and the unique identifier information of the corresponding device can be obtained through the intra-community address. In this example, the unique device identification information includes a device type ID and a device ID, where the type ID may be an access control type ID and a ladder control type ID, and if the access control type ID is set to 1 and the ladder control type ID is set to 2; the equipment IDs can respectively correspond to equipment numbers of all the access controllers or the elevator controllers, for example, the equipment IDs corresponding to the access controllers of all the unit buildings are 1, 2 and 3 \8230, the equipment IDs corresponding to the elevator controllers of all the unit buildings are 1, 2 and 3 \8230, and the like, the type IDs are used for distinguishing the access control or the elevator control, and the equipment IDs are used for distinguishing the controllers in the corresponding types.

And the identification terminal scans the two-dimensional code to obtain corresponding encrypted data.
And S105, the identification terminal decrypts the encrypted data according to the pre-stored key distributed by the corresponding community to obtain an equipment operation instruction, decodes the equipment operation instruction, and analyzes the equipment unique identification list and the elevator authorization layer number.
