All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
The embodiment of the invention provides a power switching method.
Referring to fig. 1, a flowchart of a power switching method in an embodiment of the present invention is shown, which is applied to a mobile terminal, and the method includes:
In this embodiment, when the mobile terminal falls, the gravity condition borne by the mobile terminal changes, and the acceleration data in the gravity direction also changes accordingly. The method for acquiring the acceleration data of the mobile terminal in the gravity direction in real time can be realized by adopting an acceleration sensor, and can also be realized by adopting a gravity sensor.
And step 102, if the mobile terminal is judged to be in the weightlessness state according to the acceleration data, turning off the power supply of the target device and starting timing.
In this embodiment, after the acceleration data of the mobile terminal in the gravity direction is acquired, whether the mobile terminal is in a weightless state is determined according to the acceleration data. If the mobile terminal is in the weightless state, the mobile terminal is in the rapid movement state or the falling state, at the moment, the power supply of the target device is turned off, and the timing is started. The target device can be set as a device sensitive to falling collision, such as a touch screen of a mobile terminal.
And 103, if the closing time of the power supply reaches a first set time and the mobile terminal is in a non-weightless state, turning on the power supply of the target device.
In this embodiment, when it is determined that the mobile terminal is in the weightless state, after the power of the target device is turned off, the power off time of the target device is recorded, and whether the mobile terminal is in the weightless state is determined according to the acceleration data of the mobile terminal in the gravity direction, which is obtained in real time. When the closing time of the power supply reaches a first set time and the mobile terminal is in a non-weightlessness state, the mobile terminal is not in a rapid movement state or a falling state, and the power supply of the target device is turned on at the moment. Preferably, when the off duration of the power supply reaches the first set duration, the mobile terminal is still in the weightless state, and the power supply of the target device is turned on until the mobile terminal is determined to be in the non-weightless state.
In summary, in the embodiment of the present invention, the mobile terminal obtains acceleration data of the mobile terminal in the gravity direction in real time; if the mobile terminal is judged to be in the weightlessness state according to the acceleration data, the power supply of the target device is turned off and timing is started so as to protect the target device from causing short circuit or failure of the system even if the circuit is instantly connected in a falling collision; and if the closing time of the power supply reaches a first set time and the mobile terminal is in a non-weightless state, starting the power supply of the target device. The embodiment of the invention improves the falling reliability of the mobile terminal, avoids the risk of short circuit of the circuit in the extreme acceleration scene, and improves the space utilization rate of electronic stacking.
Example two
Referring to fig. 2, a flow chart of a power switching method in another embodiment of the invention is shown.
In this embodiment, the mobile terminal is provided with an acceleration sensor, and acquires three-axis vector data of the acceleration sensor, for example, X, Y, Z three-axis acceleration data in real time.
In this embodiment, after the three-axis vector data of the acceleration sensor is acquired, whether the mobile terminal is in a weightless state is determined according to the three-axis vector data. For example, whether the mobile terminal is in a falling state is judged according to the acceleration of the Z axis, and if the acceleration of the Z axis is greater than a certain set value, the mobile terminal is judged to be in a weightless state.
Preferably, the determining whether the mobile terminal is in the weightless state may specifically include the following steps:
step one, calculating the sum of the triaxial vector data.
And step two, judging whether the absolute value of the triaxial vector data sum is smaller than a set threshold value.
And step three, if the absolute value is smaller than the set threshold, determining that the mobile terminal is in a weightless state. Specifically, if the absolute value of the sum of the three-axis vector data is smaller than a set threshold, the mobile terminal is determined to be in a weightless state, and if the absolute value of the sum of the three-axis vector data is greater than or equal to the set threshold, the mobile terminal is determined to be in a non-weightless state. The setting threshold in the embodiment of the present invention is not limited in detail, and may be set according to actual situations.
In this embodiment, considering that the falling heights of the mobile terminal are different and the impact of the generated collision on the target device is also different, in order to prevent the mobile terminal from turning off the power supply of the target device for many times, the falling safety height of the mobile terminal is set, and the mobile terminal enters a protection mechanism for turning off the power supply of the target device when the falling height of the mobile terminal is greater than the safety height. The set height of the mobile terminal falling corresponds to the second set duration, so that the duration that the mobile terminal is in the weightless state is compared with the second set duration, and whether the falling height of the mobile terminal is greater than the safety height can be judged according to the comparison result. The second set time period in the embodiment of the present invention is not limited in detail, and may be set according to actual conditions.
And 204, if the comparison result shows that the time length of the mobile terminal in the weightlessness state is less than the second set time length, clearing the time length of the mobile terminal in the weightlessness state, and executing the step of acquiring the acceleration data of the mobile terminal in the gravity direction in real time.
In this embodiment, if the duration of the mobile terminal in the weightlessness status is less than the second set duration, the duration of the mobile terminal in the weightlessness status is cleared, and the step of acquiring the acceleration data of the mobile terminal in the gravity direction in real time is returned. Specifically, whether the falling height of the mobile terminal is greater than the safety height or not is judged according to the time length of the mobile terminal in the weightlessness state, the time length of the mobile terminal in the weightlessness state is less than a second set time length, and if the falling height of the mobile terminal is less than the safety height, the influence of the falling of the mobile terminal on a target device is small, the power supply of the target device does not need to be turned off, and the step of obtaining the acceleration data in real time is returned to be executed. The second set time period is not limited in detail in the embodiment of the present invention, and may be set according to an actual situation.
And step 205, if the comparison result shows that the duration of the weightlessness status of the mobile terminal is longer than the second set duration, executing the steps of turning off the power supply of the target device and starting timing.
In this embodiment, if the duration of the weightlessness status of the mobile terminal is longer than the second set duration, it indicates that the falling height of the mobile terminal is greater than the safety height, and the falling of the mobile terminal may be dangerous for the target device, so the power supply of the target device is turned off. Specifically, the current running information of the mobile terminal is stored, the power supply of the target device is turned off, and the timing is started. For example, the user is browsing the mail currently or editing the document currently, and the mobile terminal stores the current running information, so that the operation information of the user can be protected from being lost, and the user can conveniently operate the mobile terminal after the mobile terminal turns on the target power supply. Other operations can be executed before the power supply of the target device is turned off, which is not limited in the embodiment of the present invention and can be set according to actual situations.
And step 206, if the closing time of the power supply reaches a first set time and the mobile terminal is in a non-weightless state, turning on the power supply of the target device.
And step 207, calling the stored running information of the mobile terminal.
In this embodiment, after the mobile terminal turns on the power supply of the target device, the stored running information of the mobile terminal can be automatically called, and the display interface of the mobile terminal is restored to the state before the power supply is turned off, so that the operation of the user is continuous, and the use experience of the user is improved.
In summary, in the embodiment of the present invention, the mobile terminal acquires the three-axis vector data of the acceleration sensor in real time; judging whether the mobile terminal is in a weightless state or not according to the triaxial vector data; if the mobile terminal is in the weightlessness state, comparing the duration of the mobile terminal in the weightlessness state with a second set duration; judging whether to execute the step of turning off the power supply of the target device according to the comparison result, and if the step of turning off the power supply of the target device and starting timing is executed, storing the current running information before execution; and if the closing time of the power supply reaches the first set time and the mobile terminal is in a non-weightless state, starting the power supply of the target device and calling the stored running information. The embodiment of the invention improves the falling reliability of the mobile terminal, avoids the risk of short circuit of the circuit in the extreme acceleration scene, and improves the space utilization rate of electronic stacking.
