Abstract
A door lock detection system is disclosed. The system includes a magnet flexibly attached to a strike plate. The strike plate includes an opening. The magnet extends across the opening of the strike plate in a first orientation when a bolt does not extend into the opening of the strike plate. The magnet is configured to be deflected from the first orientation to a second orientation, distinct from the first orientation, in response to the bolt being extended into the opening of the strike plate. The system includes a magnetometer configured to detect one or more magnetic fields of the magnet that is flexibly attached to the strike plate in the first orientation and in the second orientation.
Claims20
A door lock detection system, comprising:
- a magnet flexibly attached to a strike plate, wherein:
- the strike plate includes an opening;
- the magnet extends across the opening of the strike plate in a first orientation when a bolt does not extend into the opening of the strike plate;
- and
- the magnet is configured to be deflected by the bolt from the first orientation to a second orientation, distinct from the first orientation, in response to the bolt being extended into the opening of the strike plate;
- and
- a magnetometer configured to detect one or more magnetic fields of the magnet that is flexibly attached to the strike plate in the first orientation and in the second orientation.
A method, comprising:
- at a door lock detection system having:
- a magnet flexibly attached to a strike plate, wherein:
- the strike plate includes an opening;
- the magnet extends across the opening of the strike plate in a first orientation when a bolt does not extend into the opening of the strike plate;
- and
- the magnet is configured to be deflected by the bolt from the first orientation to a second orientation, distinct from the first orientation, in response to the bolt being extended into the opening of the strike plate;
- a magnetometer configured to detect one or more magnetic fields of the magnet that is flexibly attached to the strike plate in the first orientation and in the second orientation;
- and
- a controller;
- detecting, with the magnetometer, one or more magnetic fields of the magnet that is flexibly attached to the strike plate;
- determining whether the detected one or more magnetic fields correspond to the magnet being in the second orientation;
- and
- based at least in part on determining that the detected one or more magnetic fields correspond to the magnet being in the second orientation, relaying, with the controller, to at least one other system information that indicates that the bolt is engaged in the strike plate.
