The present invention aims at the problem that the existing anti-theft method cannot attract user's attention when the mobile terminal is stolen, so that the mobile terminal cannot be effectively avoided, and provides an anti-theft method, a mobile terminal and a wearable device.

Embodiment one

As shown in FIG. 1, the anti-theft method in Embodiment 1 of the present invention is applied to a mobile terminal, including:

Step 100, start the preset alarm mode of the mobile terminal;

It should be noted here that the preset alarm mode is automatically triggered and started according to the state of the mobile terminal itself.

Step 200, in the preset alarm mode, when the alarm state is triggered, an alarm signal is generated;

The main realization of the step 200 is that when the mobile terminal is in the preset alarm mode, it has a specific state. When the specific state changes, the alarm state of the mobile terminal will be triggered to remind the user that the state of the mobile terminal has occurred. Variety.

Step 300, sending the alarm signal to the wearable device connected to the mobile terminal, so that the wearable device sends an alarm to the user according to the alarm signal;

It should be noted that in step 300, the alarm signal is sent to the wearable device. The wearable device is usually worn by the user. When the wearable device receives the alarm signal from the mobile terminal, it will trigger its own alarm mechanism to warn the user. To remind the user that the mobile terminal has been moved.

It should be noted that, generally, the mobile terminal can realize the connection with the wearable device through wireless connection methods such as Bluetooth and WiFi.

It should be noted that the mobile terminal in the present invention includes, but is not limited to, a mobile phone, a tablet computer, an e-reader, etc.; the wearable device includes, but is not limited to, a smart bracelet, a smart watch, and the like.

Optionally, when the step 100 is implemented, it may include:

Step 110, within a first preset time, detect whether the user has operated the mobile terminal;

Step 110 is mainly to detect whether the user is using the mobile terminal, and this step 110 can be realized by using an existing screen lock method of the mobile terminal.

Step 120, if it is detected that the user does not operate the mobile terminal, start a preset alarm mode of the mobile terminal.

What this step 120 illustrates is that it is detected that the user has not used the mobile terminal for a period of time. At this time, it can be judged that the user does not hold the mobile terminal. At this time, in order to facilitate the user to monitor the state of the mobile terminal, the alarm mode of the mobile terminal needs to be turned on. .

It should be noted that, in this embodiment, the preset alarm state is automatically enabled by the mobile terminal. When the mobile terminal detects that the user has not operated the mobile terminal for a long time, the preset alarm mode of the mobile terminal is automatically enabled.

It should be noted that, in the present invention, the preset alarm mode includes a pocket alarm mode and a static alarm mode.

Step 110, within a first preset time, detect whether the user has operated the mobile terminal;

Step 120, if it is detected that the user does not operate the mobile terminal, start a preset alarm mode of the mobile terminal.

It should be noted that, since different alarm modes start in different ways, and the ways of triggering the alarm state in different alarm modes are also different, in this embodiment, different alarm modes are described in detail.

1. How to open the pocket alarm mode

The realization mode of above-mentioned step 120 comprises:

Step 121, acquiring the first three-dimensional acceleration coordinate value of the acceleration sensor or the gravity sensor, and judging whether the first three-dimensional acceleration coordinate value is within the first preset range;

In this step 121, it is determined whether an acceleration sensor or a gravity sensor is specifically used according to the configuration of the sensors on the mobile terminal. It should be noted that the three-dimensional acceleration coordinate values of the gravity sensor or the acceleration sensor include the acceleration coordinate values of the X axis, the Y axis, and the Z axis respectively; The coordinate value will be in a specific range, so as long as the three-dimensional coordinate value of the gravity sensor or the acceleration sensor is judged to be within the specific range, it can be known that the mobile phone may be placed in the pocket at this time.

For example, the preset range of the three-dimensional acceleration coordinates of the gravity sensor is:

X axis: -30~30; Y axis: -20~20; Z axis: -5~5;

In practical applications, the three-dimensional acceleration coordinate value of the gravity sensor obtained at the current moment is:

X axis: 0; Y axis: 10; Z axis: 0;

When comparing, the acceleration coordinate value of the X-axis obtained at the current moment will be compared with the range of the preset acceleration coordinate value of the X-axis, and the acceleration coordinate value of the Y-axis will be compared with the preset acceleration coordinate value of the Y-axis. The range of the acceleration coordinate value of the Z axis is compared with the range of the preset acceleration coordinate value of the Z axis; after the above comparison, it can be known that the coordinate values of the X axis, Y axis and Z axis of the gravity sensor at the current moment are respectively Correspondingly satisfying the preset range of acceleration coordinates of the X axis, Y axis and Z axis, that is, the three-dimensional acceleration coordinate value at the current moment is within the range of the preset three-dimensional acceleration coordinate value.

Step 122, detecting whether the potential of the infrared sensor on the mobile terminal changes;

Because when the mobile terminal is placed in the pocket, at least one of the front and back sides of the mobile terminal will be in contact with the object. When the mobile terminal is placed in the pocket, the infrared sensor will produce a level change. Therefore, the infrared sensor can be used to determine whether the mobile terminal It is judged that the mobile terminal is placed in the pocket, and usually when the mobile terminal is placed in the pocket, the level of the infrared sensor will change from high to low.

Step 123, if it is determined that the first three-dimensional acceleration coordinate value is within the first preset range and the potential of the infrared sensor changes from high to low, start the pocket alarm mode among the preset alarm modes of the mobile terminal.

When the gravity sensor (or acceleration sensor) and the infrared sensor are used for detection together, if the state of both satisfies the situation that the mobile terminal is located in the pocket at the same time, the pocket alarm mode of the mobile terminal will be turned on.

In this pocket alarm mode, the infrared sensor and the gravity sensor will also monitor the state of the mobile terminal in real time. Specifically, the implementation of step 200 is as follows:

Step 210, acquiring the second three-dimensional acceleration coordinate value of the acceleration sensor or the gravity sensor in real time, and comparing the second three-dimensional acceleration coordinate value with the first preset range;

Step 220, detecting whether the potential of the infrared sensor changes;

Step 230, if the second three-dimensional acceleration coordinate value is not within the first preset range and the potential of the infrared sensor changes from low to high, the alarm state of the pocket alarm mode is triggered and an alarm signal is generated.

When the mobile terminal is taken out of the pocket in the pocket mode, it will trigger the mobile terminal to generate an alarm signal, which is transmitted to the wearable device, and the wearable device will remind the user of the mobile terminal.

2. How to open the static alarm mode

The realization mode of above-mentioned step 120 comprises:

Step 124, within the second preset time, monitor the third three-dimensional acceleration coordinate value of the acceleration sensor or the gravity sensor;

Step 125, if it is detected that the third three-dimensional acceleration coordinate value of the acceleration sensor or the gravity sensor does not change within the second preset time, start the static alarm mode among the preset alarm modes of the mobile terminal.

Because when the mobile terminal is in a static state (such as being placed on a desktop), the three-dimensional acceleration coordinate value of its acceleration sensor or gravity sensor is in a relatively fixed state, so when the three-dimensional acceleration coordinate value of the acceleration sensor or gravity sensor is monitored. Assuming that the time has not changed, it can be proved that the mobile terminal is in a static state, and the static alarm mode of the mobile terminal will be started at this time.

In this static alarm mode, the acceleration sensor or the gravity sensor will also monitor the state of the mobile terminal in real time. Specifically, the implementation of step 200 is as follows:

Step 240, acquiring the fourth three-dimensional acceleration coordinate value of the acceleration sensor or the gravity sensor at the current moment;

Step 250, judging whether the fourth three-dimensional acceleration coordinate value is the same as the three-dimensional acceleration coordinate value at the previous moment;

Step 260, if the fourth three-dimensional acceleration coordinate value is different from the three-dimensional acceleration coordinate value at the previous moment, the alarm state of the static alarm mode is triggered and an alarm signal is generated.

In this static alarm mode, the main realization of step 200 is to monitor in real time whether the three-dimensional acceleration coordinates of the acceleration sensor or the gravity sensor are consistent with those at the previous moment. If not, it proves that the mobile terminal has been moved. In this case, the mobile terminal will be triggered to generate an alarm signal, and the alarm signal will be transmitted to the wearable device, and the wearable device will remind the user of the mobile terminal's alarm.

It should be noted that for different states of the mobile terminal, different alarm judging mechanisms are adopted, thereby ensuring reasonable monitoring of the state of the mobile terminal and avoiding false alarms as much as possible.

It should be noted that, in step 300, the wearable device may remind the user through sound, vibration, or indicator light.

It should be noted that, in order to facilitate the user to monitor the location of the mobile terminal, after the step 100, the anti-theft method further includes:

When the alarm mode is turned on, the mobile terminal is positioned in real time, and when the user needs to be alerted, the location information of the mobile terminal at the alarm time is sent to the wearable device, so that the user can clearly know the location of the mobile terminal. In case of theft, the mobile terminal can be retrieved in time.
