AI Technical Summary
Technical Problem
Existing door lock control functions based on UWB technology are relatively simple, mainly limited to unlocking, and lack the ability to determine and extend user behavior.
Method used
By installing first and second UWB anchor points in the door lock, the position of the UWB tag before and after the door is closed is determined by the signal strength difference between the UWB tag and the anchor point, and the user's entry or exit behavior is determined based on the position change, thus realizing the identification and recording of user behavior.
Benefits of technology
The door lock's control functions have been expanded, enabling it to recognize and record users' entry and exit behaviors, achieve linkage with smart devices, and improve the door lock's intelligence level.

Abstract
The present disclosure relates to a user behavior determination method and device, a door lock and a storage medium, and is applied to a door lock. The door lock is provided with a first UWB anchor point installed on an inner lock and a second UWB anchor point installed on an outer lock. The user behavior determination method comprises: in response to determining that a preset condition is met, enabling the first UWB anchor point and the second UWB anchor point to perform UWB tag scanning; determining the position of the UWB tag before and after the door is closed based on the signal strength of the UWB tag and the first UWB anchor point and the signal strength of the UWB tag and the second UWB anchor point, the position comprising being located inside the door and being located outside the door; and determining the user behavior of the user indicated by the UWB tag based on the position of the UWB tag before and after the door is closed. Through the present disclosure, the door lock can acquire the user behavior of the user indicated by the UWB tag.
