The following describes the specific flow of the overvoltage protection control method in detail.
The mobile terminal 100 is provided with an external port (e.g., a USB port, a TYPEC interface, etc.). When the external port is immersed in liquid or leaked liquid, the input voltage of the external port may become high after a certain period of time, and the high input voltage may cause a short circuit of the main board of the mobile terminal 100. Therefore, the mobile terminal 100 further includes an overvoltage Protection chip (OVP chip) for performing overvoltage Protection. The overvoltage protection chip is arranged between an input voltage VIN pin of an external port of the mobile terminal 100 and a PMIC input voltage, and the overvoltage protection chip is electrically connected with the input voltage VIN pin of the external port of the mobile terminal 100.
Step S110, detecting posture change data of the mobile terminal 100.
In this embodiment, the mobile terminal 100 may detect the posture change data of the mobile terminal 100 through timing detection, triggering detection by a specific condition (for example, the current angular velocity of the mobile terminal 100 exceeds a set angular velocity), or constant detection.
The mobile terminal 100 may further include a sensor (e.g., an angular velocity meter, a gyroscope, etc.) for detecting attitude change data of the mobile terminal 100. When the posture change of the mobile terminal 100 is required to be detected, the sensor may be controlled to enter a working state, so as to obtain posture change data.
Step S120, comparing the detected posture change data with a preset posture change data threshold to obtain a comparison result.
In the embodiment of the present embodiment, the posture change data of the mobile terminal 100 under the condition (for example, falling, throwing, etc.) that may cause the mobile terminal 100 to enter the liquid is detected in advance and stored as the preset posture change data.

Wherein the changed time value is a time length during which the angular velocity is continuously greater than a preset angular velocity.

And a substep S123 of determining that the posture change data is greater than a preset posture change data threshold when the time value of the change is greater than the time threshold of the change and the angular velocity change value is greater than the angular velocity change threshold.
Specifically, a sensor for obtaining an angular velocity of the mobile terminal 100, such as a gyroscope, is provided in the mobile terminal 100. At rest, the output value of the gyroscope is substantially constant; during shaking, the output value of the gyroscope changes. Comparing the angular velocity obtained by the gyroscope with a preset angular velocity, and obtaining the time length of the angular velocity continuously greater than the preset angular velocity as the time value of the change in a manner of timing at the starting point of the angular velocity greater than the preset angular velocity.

Specifically, the mobile terminal 100 is provided with a sensor for obtaining an acceleration of the mobile terminal 100, such as a three-axis accelerometer. The change of the acceleration value of the mobile terminal 100 can be detected by the three-axis accelerometer. Comparing the acceleration of each axial direction obtained by the triaxial accelerometer with the preset acceleration, and obtaining the time length of the acceleration continuously greater than the preset acceleration as the time value of the change in a mode of timing at the starting point of the acceleration greater than the preset acceleration. Further, an acceleration change value may also be obtained from the obtained acceleration.
And comparing the obtained time value of the change with the time threshold value of the change, and comparing the acceleration change value with the acceleration change threshold value, thereby judging whether the posture change data conforms to the preset posture change data threshold value.
When the time value of the change is greater than the time threshold of the change and the acceleration change value is greater than the acceleration change threshold, determining that the posture change data is greater than a preset posture change threshold, that is, the posture change data conforms to the preset posture change data threshold. Otherwise, the posture change data is judged to be smaller than a preset posture change threshold value, namely the posture change data does not accord with the preset posture change data threshold value.
Referring to fig. 5, fig. 5 is a third schematic flowchart illustrating the sub-steps included in step S120 in fig. 2. The step S120 may include a substep S121, a substep S122, a substep S125, and a substep S128.
In this embodiment, the attitude change data threshold includes a time threshold of change, an angular velocity change threshold, and an acceleration change threshold, and the attitude change data includes a time value of change, an angular velocity change value, and an acceleration change value. And the time value of the change is the time length that the angular velocity is continuously greater than the preset angular velocity and the acceleration is continuously greater than the preset acceleration.

and a substep S128 of determining that the posture change data is greater than a preset posture change data threshold when the time value of the change is greater than the time threshold of the change, the angular velocity change value is greater than the angular velocity change threshold, and the acceleration change value is greater than the acceleration change threshold.
Specifically, the mobile terminal 100 is provided with a sensor for obtaining an angular velocity and an acceleration of the mobile terminal 100, such as a gyroscope and a three-axis accelerometer. The angular velocity of the mobile terminal 100 is obtained by a gyroscope, and the acceleration of each axis of the mobile terminal 100 is obtained by a triaxial accelerometer. The angular velocity is compared with a preset angular velocity, the acceleration is compared with a preset acceleration, and the time length that the angular velocity is continuously greater than the preset angular velocity and the acceleration is continuously greater than the preset acceleration can be obtained as the time value of the change in a mode of timing at the starting point that the angular velocity is greater than the preset angular velocity and the acceleration is greater than the preset acceleration.
And comparing the obtained time value of the change with the time threshold value of the change, comparing the change value of the angular velocity with the change threshold value of the angular velocity, and comparing the change value of the acceleration with the change threshold value of the acceleration, thereby judging whether the posture change data conforms to the posture change data threshold value set in advance.
When the time value of the change is greater than the time threshold of the change, the angular velocity change value is greater than the angular velocity change threshold, and the acceleration change value is greater than the acceleration change threshold, it is determined that the posture change data is greater than a preset posture change threshold, that is, the posture change data conforms to a preset posture change data threshold.
And step S130, when the comparison result shows that the attitude change data is larger than a preset attitude change data threshold, controlling the overvoltage protection chip to work.
In this embodiment, the posture change data is greater than a preset posture change data threshold, that is, the posture change data conforms to the preset posture change data threshold, and represents that the mobile terminal 100 is in a posture (for example, falling, throwing, etc.) that may cause the mobile terminal 100 to enter the liquid. In this case, the overvoltage protection chip may be activated through the bus interface to control the external switch circuit, so as to cut off the path between the VIN and the PMIC, and prevent the mobile terminal 100 from being corroded by the liquid to cause an internal short circuit, so as to perform advanced protection.
By the above manner, after the mobile terminal 100 enters the liquid, high voltage, high current, high temperature and the like caused by liquid corrosion are avoided, and further time delay, misjudgment and the like caused by controlling the operation of the overvoltage protection chip by the high voltage, the high current, the high temperature and the like are avoided. However, since different leakage has different impedances, the voltage threshold, the current threshold, the temperature threshold, and the like, which correspond to different leakage, are different. However, the set voltage threshold, the set current threshold, and the set temperature threshold corresponding to the operation of the overvoltage protection chip are fixed, which may cause erroneous determination.

The prompt information can be in a mode of vibration, popup window, ringing and the like.
Further, if the posture change data does not meet the set posture change threshold, the overvoltage protection function of the overvoltage protection chip does not need to be started, so that the mobile terminal 100 can normally operate.
