Embodiments of the present application will be described below in conjunction with the accompanying drawings.

Please refer to FIG. 1. FIG. 1 is a schematic flow diagram of a drop detection method provided by an embodiment of the present application, which is applied to a mobile terminal. The drop detection method includes:

S101. When the mobile terminal detects that the mobile terminal is switched from an overweight state to a weightless state, determine a first speed of the mobile terminal.

Among them, for the falling event of the mobile terminal throwing scene, the mobile terminal originally recognizes the falling state based on the acceleration, that is, it can be considered that the mobile phone is in the falling state when multiple adjacent groups of acceleration values are detected close to the acceleration of gravity. Therefore, in the throwing scene, the mobile terminal After leaving the hand, the acceleration is collected by the accelerometer. When the collected acceleration is the acceleration of gravity, it can be recognized that the mobile terminal is in a falling state and start timing the fall. However, in the upward throwing scene, the mobile terminal is actually still rising. It starts to fall after rising to the highest point, so the actual drop overestimation of the mobile terminal should be the height from the highest point to the ground.

Among them, in the drop identification strategy of the prior art, the drop height will be calculated according to the drop duration of the mobile terminal. Drop height, the starting point of timing should be the moment when the mobile terminal is at the highest point, so in order to avoid errors, after detecting that the mobile terminal is in the falling state and starting the fall timing to obtain the duration of the fall, the duration of the rising process of the mobile terminal needs to be subtracted In order to obtain the free fall time of the mobile terminal.

Among them, the duration of the mobile terminal's ascent process can be calculated from the initial speed, and the mobile terminal can statistically analyze the acceleration value collected by the accelerometer to obtain the corresponding acceleration value and acceleration time after the mobile terminal is out of the hands in most cases, and then further calculation To the initial speed of the mobile terminal, the duration of the ascent process of the mobile terminal can be calculated after the initial speed is obtained.

Among them, the mobile terminal is in an overweight state during the acceleration process before leaving the hand, and is in a weightless state after the mobile terminal is out of the hand. When the mobile terminal is detected to switch from the overweight state to the weightless state, the mobile terminal can be calculated. A speed. The first speed is the speed when the mobile terminal is out of the hand.

S102. The mobile terminal determines a free fall time of the mobile terminal according to the first speed.

Wherein, after the first speed of the mobile terminal is obtained, the up-throwing duration of the mobile terminal can be calculated, and then the falling duration of the mobile terminal in a free-fall state can be calculated.

S103. The mobile terminal calculates a target drop height of the mobile terminal according to the free fall time.

Wherein, the falling state of the mobile terminal upward throwing scene includes a rising state and a falling state, and the falling state is a free-falling state, and the actual falling height of the mobile terminal can be calculated according to the length of time the mobile terminal is in the free-falling body.

It can be seen that in the embodiment of the present application, the mobile terminal first determines the first speed of the mobile terminal when it detects that the mobile terminal is switched from an overweight state to a weightless state, and secondly, determines the first speed of the mobile terminal according to the first speed. The free fall time of the mobile terminal, and finally, calculate the target drop height of the mobile terminal according to the free fall time. Since the mobile terminal may not fall directly downward when it falls, the first upward speed of the mobile terminal can be determined when it is detected that the mobile terminal is in an overweight state, so that the time when the mobile terminal falls to the highest position can be determined and then determined The free-fall time is calculated to obtain the drop height of the mobile terminal, which is beneficial to improving the accuracy and reliability of the detected drop height.

In a possible example, the determining the first speed of the mobile terminal includes: acquiring multiple sets of historical acceleration records of the mobile terminal in an overweight state, the historical acceleration records including acceleration duration and acceleration value; according to the The multiple sets of historical acceleration records determine the first speed of the mobile terminal.

Wherein, in order to obtain the first speed of the mobile terminal, multiple sets of historical acceleration records of the mobile terminal in an overweight state can be obtained. The historical acceleration records include acceleration duration and acceleration value, and the first speed of the mobile terminal is determined according to the multiple sets of historical acceleration records. For example, obtain the latest 100 sets of historical acceleration records before the mobile terminal is out of the hands. Each set of historical acceleration records includes acceleration duration and acceleration value, which are obtained by accelerometer statistics. According to these 100 sets of historical acceleration records, determine the first speed of the mobile terminal .

It can be seen that, in this example, the first speed is the speed after the mobile terminal is out of the hand, and the first speed can be determined by performing statistical analysis on multiple sets of historical acceleration records of the mobile terminal, thus, it is beneficial to determine the time when the mobile terminal rises to the highest point of fall. time.

In a possible example, the historical acceleration records include an acceleration direction; the determining the first speed of the mobile terminal according to the multiple sets of historical acceleration records includes: obtaining at least one speed from the multiple sets of historical acceleration records A set of historical acceleration records with an upward acceleration direction; according to the acceleration duration and acceleration value of the at least one set of historical acceleration records, it is determined that the average speed after acceleration is the first speed.

Wherein, the historical acceleration record includes the acceleration direction. After obtaining multiple sets of historical acceleration records of the mobile terminal, at least one set of historical acceleration records with an upward acceleration direction can be obtained from the multiple sets of historical acceleration records. According to at least one set of historical acceleration records The acceleration duration and the acceleration value determine the average value of the accelerated speed as the first speed. For example, obtain 100 sets of historical acceleration records of the mobile terminal, filter out 30 consecutive sets of historical acceleration records in the upward direction, determine the accelerated speed according to the acceleration duration and acceleration value of each set of historical acceleration records, and match the 30 sets of historical acceleration records to The average value of the speed is stored in the mobile terminal as the first speed.

It can be seen that in this example, the first speed is obtained by statistical analysis of multiple sets of historical acceleration records in the upward direction of the mobile terminal, and the duration of the mobile terminal's ascent process can be calculated through the first speed, that is, according to the formula v=g*t, v is The first speed, g is the acceleration of gravity, and t is the duration of the ascent process that needs to be calculated.

In a possible example, the falling state of the mobile terminal includes a first falling state and a second falling state, the first falling state is a weightless state in which the moving direction of the mobile terminal is upward, and the second falling state The state is a weightless state in which the moving direction of the mobile terminal is downward; the determining the free-fall time of the mobile terminal according to the first speed includes: acquiring the falling time of the mobile terminal, and the falling time includes the The time when the mobile terminal is in the first falling state and the second falling state; determine the time when the mobile terminal is in the first falling state according to the first speed; according to the falling time and the time when the mobile terminal is in The time of the first falling state determines that the time when the mobile terminal is in the second falling state is the free fall time.

Wherein, the falling state in the upward throwing scene of the mobile terminal includes a first falling state and a second falling state, the first falling state is a weightless state in which the moving direction of the mobile terminal is upward, and the second falling state is a weightless state in which the moving direction of the mobile terminal is downward , when determining the free fall time of the mobile terminal according to the first speed, the fall time of the mobile terminal can be obtained first, and the fall time includes the time of the first fall state and the time of the second fall state, that is, the mobile terminal is out of the hand.

Wherein, since the time when the mobile terminal is in the first falling state can be obtained according to the first speed and the formula, the time when the mobile terminal is in the second falling state can be obtained by subtracting the falling time from the time in the first falling state, that is, the time when the mobile terminal is in the second falling state free fall time.

It can be seen that in this example, the time when the mobile terminal is in free fall can be obtained by subtracting the time when the mobile terminal rises to the highest point from the total time that the mobile terminal is in the falling state, and thus the time in which the mobile terminal is thrown up can be calculated. Accurate drop height.

In a possible example, the determining the free fall time of the mobile terminal according to the first speed includes: starting timing when it is detected that the first speed decreases to zero; When the speed increases to a second speed and then decreases to zero, stop counting, the counting time is the free fall time, and the second speed is the maximum speed of the mobile terminal in the second falling state.

Wherein, after the first speed of the mobile terminal is determined, the real-time speed of the mobile terminal can be detected, the timing starts when the first speed is detected to be reduced to zero, and the movement speed of the mobile terminal is increased from zero to the second when it is detected. Stop timing when the speed decreases to zero, which means that the mobile terminal fell to the ground after leaving the hands, and the obtained timing time is the time for the mobile terminal to fall freely, and the second speed is the maximum movement speed of the mobile terminal in the second falling state .

It can be seen that in this example, the free fall time of the mobile terminal is determined by the first speed. After the first speed decays to zero, it means that the mobile terminal has risen to the highest point. At this time, the timing is started, and the timing is stopped after the mobile terminal falls to the ground. , the free fall time of the mobile terminal can be obtained, and then the falling height of the mobile terminal upward throwing scene can be accurately calculated.
