Abstract
It is provided a lock assembly comprising: a striking plate assembly comprising an aperture and a magnetometer arranged in proximity of the aperture; a bolt being displaceable to enable movement through the aperture of the striking plate assembly, the bolt comprising a magnet; and a sensor device for detecting proximate presence of an object, wherein the sensor device is configured to power up the magnetometer when the sensor device detects proximate presence of an object; wherein the lock assembly is configured to detect, using the magnetometer and magnet when the bolt is in a protruded position through the aperture.
Claims12
A lock assembly comprising:
- a striking plate assembly comprising an aperture and a magnetometer arranged in proximity of the aperture;
- a bolt being displaceable to enable movement through the aperture of the striking plate assembly, the bolt comprising a magnet;
- and
- a sensor device comprising a proximity sensor for detecting proximate presence of an object, wherein the proximity sensor is separate from the magnetometer, and wherein the sensor device is configured to power up the magnetometer based on the sensor device detecting proximate presence of an object;
- wherein the lock assembly is configured to detect, using the magnetometer and magnet, when the bolt is in a protruded position through the aperture.
A method, performed by a lock assembly comprising a striking plate assembly and a bolt being displaceable to enable movement through an aperture of the striking plate assembly, the method comprising:
- powering up a magnetometer of the striking plate assembly based on the lock assembly detecting, using a proximity sensor of a sensor device of the striking plate assembly, proximate presence of an object, wherein the proximity sensor is separate from the magnetometer;
- and
- detecting, using the magnetometer and a magnet of the bolt, when the bolt is in a protruded position through the aperture.
A non-transitory computer readable medium comprising computer program code which, when run on a lock assembly comprising a striking plate assembly and a bolt being displaceable to enable movement through an aperture of the striking plate assembly, causes the lock assembly to:
- power up a magnetometer of the striking plate assembly based on the lock assembly detecting, using a proximity sensor of a sensor device of the striking plate assembly, proximate presence of an object, wherein the proximity sensor is separate from the magnetometer;
- and
- detect, using the magnetometer and a magnet of the bolt, when the bolt is in a protruded position through the aperture.
