Embodiment 1

[0065] refer to figure 1 , propose the method for detecting the shedding of the wearable device according to the first embodiment of the present invention, and apply the wearable device, the method includes the following steps:

[0066] S11. Detect whether the wearable device is in a falling state through the acceleration sensor.

[0067] The wearable device described in the embodiment of the present invention mainly refers to a wearable device worn on a pet, of course, it may also be a wearable device worn on a human body, such as a wearable device worn on a child.

[0068] A switch button can be set on the wearable device, and the wearable device can be turned on or off through the switch button. When the wearable device is turned on, it can automatically enter the fall-off detection mode, or the user can remotely control the wearable device to enter the fall-off detection mode through a terminal device (such as a mobile terminal such as a mobile phone). When entering the ...

Embodiment 2

[0095] refer to figure 2 , propose a method for detecting that a wearable device falls off according to a second embodiment of the present invention, the method includes the following steps:

[0096] S21. Using the 3D acceleration sensor to regularly detect the acceleration a1 in the Z-axis direction at an interval of time t1. It is judged whether the acceleration a1 is equal to the acceleration of gravity g, and if it is equal to the acceleration of gravity, step S22 is executed.

[0097] In the embodiment of the present invention, a switch button can be set on the wearable device, and the wearable device can be turned on or off through the switch button. When the wearable device is turned on, it can automatically enter the fall-off detection mode, or the user can remotely control the wearable device to enter the fall-off detection mode through a terminal device (such as a mobile terminal such as a mobile phone). When entering the falling-off detection mode, step S21 is exec...

Embodiment 3

[0110] refer to image 3 , the device for detecting the falling off of the wearable device according to the third embodiment of the present invention is proposed. The device is applied to the wearable device and includes a first detection module, a second detection module and a fall-off warning module, wherein:

[0111] The first detection module: for detecting whether the wearable device is in a falling state through the acceleration sensor. When the falling state is detected, the second detection module is notified.

[0112] Specifically, the first detection module may detect the drop state of the wearable device in the following manner:

[0113] Optionally, the first detection module may detect the first acceleration of the wearable device in the vertical direction through an acceleration sensor (such as a 3D acceleration sensor) in real time or periodically, and when it detects that the first acceleration is equal to the acceleration of gravity, determine that the wearabl...

Abstract

The invention discloses a method and a device for detecting wearable device disengagement. The method comprises the following steps: detecting whether the wearable device is in a dropping state by acceleration transducers; if the wearable device is in a dropping state, detecting whether the wearable device is in a stationary state after a predetermined time has elapsed; determining the wearable device is disengaged when the wearing device is in a stationary state and warning for falling state. Thus, by detecting the state of the wearable device, when the wearable device has experienced a dropping state and a stationary state, it is determined that the wearable device disengagement and the warning for falling shall be given in time. It is possible to promptly detect whether the wearable device is disengaged by the state change way of the embodiment of invention and due to the high detection accuracy, it's rare to make misjudgment and cause interference to the user so that warnings can be given to the user in time when the wearable device is disengaged and then the user may find the lost part in a timely manner for prevention of loss.

Description

technical field [0001] The present invention relates to the technical field of pet smart devices, in particular to a method and device for detecting that a wearable device falls off. Background technique [0002] With the improvement of people's living standards, more and more families keep pets, and some families have regarded pets as part of the family. However, busy work and life make people have no time to take care of pets all the time, and pet wearable devices can monitor pets in real time, allowing people to understand pets' emotions and various physiological changes anytime, anywhere, so it has gradually become an essential device for keeping pets. [0003] When the wearable device is worn on the pet, the pet will feel uncomfortable and will try to break free from the wearable device, which often results in the wearable device falling off the pet. If the user (breeder) cannot find out in time, the wearable device will be lost, thereby causing unnecessary losses to t...
