Abstract

This disclosure relates to a method for a wearable device as well as a wearable device and a positioning system associated therewith. The wearable device is attached to a wearer through an attachment assembly. The method comprises steps of collecting identity information of an operator operating the wearable device; detecting whether the collected identity information matches with pre-stored target identity information; inhibiting detachment of the attachment assembly from the wearer if the collected identity information does not match with the pre-stored target identity information; acquiring position information of the wearable device; and sending the collected identity information along with the position information to a monitoring terminal for the wearable device. Therefore, usage security and reliability of the wearable device are improved.

First claim

The invention claimed is:

1. A method for a wearable device, the wearable device being attached to a wearer via an attachment assembly, the method comprising steps of:
collecting identity information of an operator who is to take off the wearable device from the wearer;
detecting whether the collected identity information matches with pre-stored target identity information of a target operator who is authorized to take off the wearable device, wherein the operator and the wearer are different people;
preventing the operator from taking off the wearable device from the wearer by inhibiting detachment of the attachment assembly from the wearer and acquiring position information of the wearable device upon detection of a mismatch between the collected identity information and the target identity information; and
sending the collected identity information along with the position information to a monitoring terminal for the wearable device.

2. The method according to claim 1 , wherein after said acquiring step, the method further comprises:
acquiring distance information between the wearable device and a preset position; and
sending the distance information to the monitoring terminal.

3. The method according to claim 2 , wherein after said acquiring distance information between the wearable device and a preset position, the method further comprises:
comparing a distance indicated by the distance information with a distance threshold; and
if the distance indicated by the distance information is greater than the distance threshold, sending indication information to the monitoring terminal such that the monitoring terminal sends out a first alarm signal based on the indication information.

4. The method according to claim 3 , wherein the method further comprises:
enabling to send out a second alarm signal at the wearable device if the distance indicated by the distance information is greater than the distance threshold.

5. The method according to claim 1 , wherein the identity information of the operator is an image of finger vein of the operator, and
said collecting step comprises: capturing the image of finger vein of the operator with an infrared charge-coupled device (CCD) camera.

6. The method according to claim 1 , wherein after said detecting step, the method further comprises:
allowing the attachment assembly to be detached from the wearer if the collected identity information matches with the target identity information.

7. A wearable device, comprising: an attachment assembly, an identity identifier, a positioner, and a communicator,
the attachment assembly being configured for attaching the wearable device to a wearer;
the identity identifier being configured for collecting identity information of an operator who is to take off the wearable device from the wearer and is different person from the wearer, detecting whether the collected identity information matches with pre-stored target identity information of a target operator who is authorized to take off the wearable device, preventing the operator from taking off the wearable device from the wearer by inhibiting detachment of the attachment assembly from the wearer if the collected identity information and the pre-stored target identity information do not match, and sending the collected identity information to the communicator;
the positioner being configured for acquiring position information of the wearable device upon detection of a mismatch between the collected identity information and the pre-stored target identity information and sending the position information to the communicator; and
the communicator being configured for sending the collected identity information along with the position information to a monitoring terminal for the wearable device.

8. The wearable device according to claim 7 , wherein the identity identifier comprises: an identifier submodule, a storage submodule and a controller submodule,
the identifier submodule being configured for collecting identity information of the operator;
the storage submodule being configured for storing the target identity information; and
the controller submodule being configured for matching the collected identity information with the target identity information and determining whether to send a control instruction for detachment to the attachment assembly based on a result of the matching.

9. The wearable device according to claim 8 , wherein the wearable device further comprises:
a protective shell, and the positioner, the identity identifier, the attachment assembly and the communicator being arranged within the protective shell;
the attachment assembly comprising a motor, a spring, a metal handle and an engagement part arranged on a side surface of the protective shell;
the spring being configured for controlling displacement of the metal handle through transitions between a compressed state and a free state;
the metal handle being configured for, when the spring is in the compressed state, being compressed by the spring to join the engagement part, so as to enclose a closed space together with the engagement part and the side surface of the protective shell, and when the spring is in the free state, being displaced under an external force to separate from the engagement part to form a gap therebetween; and
the motor being configured for producing a corresponding movement based on a control instruction of the controller submodule so as to control a state transition of the spring.

10. The wearable device according to claim 8 , wherein
the positioner is further configured for acquiring distance information between the wearable device and a preset position, and sending the distance information to the controller submodule; and
the controller submodule is configured for sending the distance information to the monitoring terminal via the communicator.

11. The wearable device according to claim 10 , wherein
the controller submodule is further configured for, when a distance indicated by the distance information is detected to be greater than a distance threshold, sending indication information to the monitoring terminal via the communicator such that the monitoring terminal sends out a first alarm signal based on the indication information.

12. The wearable device according to claim 11 , wherein
the controller submodule is further configured for, when the distance indicated by the distance information is detected to be greater than the distance threshold, instructing to send out a second alarm signal at the wearable device.

13. The wearable device according to claim 9 , wherein the identity information of the operator is an image of finger vein of the operator and the identity identifier submodule is a vein recognition submodule, and
further comprises a sensing region arranged on a surface of the protective shell such that when the operator places his/her finger on the sensing region, the identifier submodule can capture the image of finger vein of the operator with an infrared charge-coupled device (CCD) camera.

14. The wearable device according to claim 11 , wherein the wearable device further comprises a displayer module arranged on a surface of the protective shell, the displayer module being configured for displaying time, a matching result of the collected identity information and the target identity information, the alarm signal(s) and/or any operation prompt(s) corresponding to the attachment assembly.

15. A positioning system comprising a wearable device according to claim 7 and a monitoring terminal for monitoring the wearable device.
