Abstract
An electronic door opening/closing apparatus and an electronic door opening/closing detection method, apparatus, and device are disclosed. The electronic door opening/closing apparatus includes: an electronic lock, disposed at a side-hinged door and configured to limit a turn of a door panel of the side-hinged door when the electronic lock is locked; a turning detector, disposed at the side-hinged door and configured to detect a turning parameter of the door panel of the side-hinged door to generate a turning parameter signal; a position detector, disposed at the side-hinged door and configured to generate a door state signal based on a position-approaching condition; and a main controller, configured to determine an open or closed state of the side-hinged door. The turning parameter signal is combined with the door state signal to accurately determine the open or closed state of the side-hinged door, and to effectively prevent malicious lock deception.
