  • Method and device for door monitoring and door monitoring system including such a device
    Patent number: 10984639
    Abstract: A monitoring method to detect a state of a door provided with a locking system. The method comprises the following steps: a measurement step during which a mechanical wave sensor measures a signal corresponding to a mechanical wave propagated in the door; a step of comparison between a reference signal stored in the memory and the mechanical wave signal in order to detect a state of the door. The reference signal is measured by the mechanical wave sensor while the locking system of the door is actuated.
