Abstract
A lock monitoring device (10, 70, 80) comprises a sensor (101) configured to sense a rotation degree of a lock with respect to a predefined direction, a controller (103) configured to determine the status of the lock based on the sensed rotation degree from the sensor (101), and a communication module (105) configured to communicate with an external device. The controller (103) is further configured to, upon detecting a change in the status of the lock, control the communication module (105) to transmit the status of the lock to the external device. And a method and system for monitoring a lock are also provided.
Claims16
A lock monitoring device comprising:
- a sensor configured to sense a rotation degree of a lock with respect to a predefined direction;
- a controller configured to determine the a status of the lock based on the sensed rotation degree from the sensor;
- and
- a communication module configured to communicate with an external device;
- wherein the controller is further configured to, upon detecting a change in the status of the lock, control the communication module to transmit the status of the lock to the external device.
A method for monitoring a lock, the method comprising:
- detecting a rotation degree of a lock with respect to a predefined direction;
- determining a the status of the lock based on the detected rotation degree;
- and
- upon detecting a change in the status of the lock, transmitting the status of the lock to an external device.
A system for monitoring a lock, the system comprising:
- a lock monitoring device
- configured to communicate with the lock monitoring device;
- wherein the lock monitoring device comprises:
- a sensor configured to sense a rotation degree of a lock with respect to a predefined direction;
- a controller configured to determine the status of the lock based on the sensed rotation degree from the sensor;
- and
- a communication module configured to communicate with a the first external device;
- wherein the controller is further configured to, upon detecting a change in the status of the lock, control the communication module to transmit the status of the lock to the first external device, and
- the first external device is further configured to present the status of the lock to a user.
