As an example, the lock authorization information may be an authorization credential for a lock to be unlocked in a target lock operation task.
In practical application, an operation work order is assigned on the intelligent lock management platform by an administrator, so that operation information of a target lock operation task can be acquired, and the intelligent lock management platform can generate an authorization certificate for a lock to be unlocked in the operation aiming at the target lock operation task, namely lock authorization information corresponding to the target lock operation task.
