Abstract
A door access control system (9) with a cloud function includes a door lock (10) mounted to a door (435). A door lock controller (611) is mounted in the door (435) and is electrically connected to the door lock (10). A wireless charging device (511) is electrically connected to the door lock controller (611). A main control unit (659) is provided for operating the door lock controller (611). The door access control system (9) further includes a cloud server (711) that can be connected to the door lock controller (611). The main control unit (659) can be connected to and log in the cloud server (711).
