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 application.
The following are detailed below.

Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Mobile terminals may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems, as well as various forms of User Equipment (UE), Mobile Stations (MS), terminal Equipment (terminal device), and the like, having wireless communication capabilities.
The following describes embodiments of the present application in detail.
Referring to fig. 1, a schematic flow chart of a drop detection method according to an embodiment of the present application is shown, where the method includes:
step 101: and the mobile terminal detects the acceleration value of the mobile terminal in real time through the acceleration sensor.
Wherein, if the mobile terminal determines that the acceleration value in the X-axis direction is a through the acceleration sensorxAcceleration value in Y-axis direction of ayAnd an acceleration value of a in the Z-axis directionzThen the acceleration value of the mobile terminal is
Step 102: under the condition that the acceleration sensor continuously detects that the acceleration value of the mobile terminal is larger than or equal to a first threshold value in a first period, and the acceleration sensor continuously detects that the acceleration value of the mobile terminal is smaller than or equal to the first threshold value in a second period, the mobile terminal determines that the mobile terminal has a falling event, wherein the first period is earlier than the second period, and the first period is adjacent to the second period.
In general, when the mobile terminal is supported by things (such as hands, tables, and the like), the mobile terminal detects that the mobile terminal is only under the action of gravity through an acceleration sensor, the mobile terminal determines that acceleration values in two directions of an X axis and a Y axis are both 0, the acceleration value in the direction of the Z axis is a gravity acceleration value, and in this case, the acceleration value of the mobile terminal is a gravity acceleration value; when the mobile terminal has no object support (for example, the mobile terminal falls from a hand or a table), the mobile terminal is in a free-fall state, the acceleration sensor is also in the free-fall state, the acceleration sensor and the mobile terminal are relatively static, the mobile terminal detects that the mobile terminal is not affected by external force through the acceleration sensor, the mobile terminal determines that the acceleration values in the three directions of the X axis, the Y axis and the Z axis are 0, and the acceleration value of the mobile terminal is zero in this case.
In general, when the mobile terminal falls from a human hand or a table, the acceleration value of the mobile terminal changes from the gravitational acceleration value to zero; when the mobile terminal is in a falling process, the acceleration value of the mobile terminal is kept zero; the acceleration value of the mobile terminal is changed from the gravity acceleration value to zero, which is a gradual change process, and the acceleration value in the process can be detected in real time by an acceleration sensor of the mobile terminal.
The first threshold value can be user-defined or user-defined by the mobile terminal, and is greater than zero and smaller than the gravitational acceleration value.
And the acceleration value corresponding to the ending time node of the first time period is the same as the acceleration value corresponding to the starting time node of the second time period.
For example, as shown in FIG. 2, assume that the first threshold is 5m/s2In a first period (t)1-t2) The acceleration value of the mobile terminal is gradually reduced from the gravitational acceleration value to 5m/s2(satisfying that the acceleration value of the mobile terminal is greater than or equal to the first threshold value during the first period), and during the second period (t)2-t3) Acceleration value of mobile terminal from 5m/s2Reducing to zero and keeping zero for a preset time (the acceleration value of the mobile terminal in the second time period is less than or equal to the first threshold), wherein the preset time is t4And t3The mobile terminal determines that a drop event occurs.
Therefore, in the embodiment of the application, when the mobile terminal is dropped, the acceleration value of the mobile terminal is reduced from the gravity acceleration value to zero, the change of the acceleration value is a gradual change process, and the acceleration value in the gradual change process can be detected by the acceleration sensor. According to the method and the device, the acceleration value continuously detected in the first time period is larger than or equal to the first threshold value, and the acceleration value continuously detected in the second time period is smaller than or equal to the first threshold value, so that the acceleration value of the mobile terminal is gradually changed, and the falling event of the mobile terminal is further determined.
In an embodiment of the present application, a sum of a duration of the first period and a duration of the second period is greater than or equal to a fourth threshold.
The duration of the first period may be equal to or different from the duration of the second period.
The fourth threshold may be user-defined, or may be user-defined by the mobile terminal.
The second time interval is a time interval corresponding to the preset time interval when the acceleration value of the mobile terminal is reduced from the first threshold value to zero and the acceleration value is kept to be zero, and the preset time interval can be user-defined or user-defined by the mobile terminal.
Generally, when the mobile terminal falls from a certain height (for example, less than or equal to 15cm) to a desk, the time required for the process is very short, and the influence on the mobile terminal is almost negligible and is not marked as a falling event; when the mobile terminal is dropped from a target height range (e.g., 80cm-120cm) onto a desk, the time required for this process is relatively long and the impact on the mobile terminal is severe, which is marked as a drop event.
It can be seen that in the embodiment of the present application, the sum of the duration of the first time period and the duration of the second time period is greater than or equal to the fourth threshold, so that a non-falling event in which the impact on the mobile terminal from a certain height (for example, less than or equal to 15cm) of falling to the surface of an impact object is almost negligible can be excluded.
In an embodiment of the present application, the mobile terminal further includes an audio component, and before determining that the mobile terminal has a drop event, the method further includes:
at a target moment, the mobile terminal starts the audio component, wherein the target moment is the moment when the acceleration value of the mobile terminal is changed into zero;
the mobile terminal collects audio information through the audio component;
the mobile terminal determines that the volume of the audio information is greater than or equal to a second threshold.
The second threshold is used for representing the minimum volume of the mobile terminal in a falling event; the second threshold value can be user-defined or mobile terminal-defined.
Specifically, if the time that the mobile terminal is kept at the acceleration value of zero is long, the influence on the mobile terminal may be negligible in some cases, for example, the user throws the mobile terminal onto a softer object (such as a quilt, etc.), so that it is necessary to further determine the sound level when the mobile terminal collides with an impact object in such a case, and if the sound level is too large, the mobile terminal is collided with a harder impact object, and the influence on the mobile terminal is large, and the sound level is recorded as a falling event; otherwise, it is not recorded as a fall event.
In an embodiment of the present application, after the mobile terminal determines that a drop event occurs to the mobile terminal, the method further includes:
the mobile terminal determines the material of a collision object impacted by the falling event of the mobile terminal;
the mobile terminal determines a target acceleration value, wherein the target acceleration value is the maximum acceleration value detected by the acceleration sensor after the second time period;
the mobile terminal determines the target falling damage degree corresponding to the target acceleration value and the material of the collision object according to the acceleration value and the mapping relation between the material and the falling damage, and reports the target falling damage degree.
At present, a user usually takes certain protective measures for a mobile terminal, such as using a mobile phone protective shell to protect a rear shell and a side surface of a smart phone, and using a toughened film or a hydrogel film to protect a screen of the smart phone, when the mobile terminal falls, the screen of the mobile terminal is usually damaged greatly, and the damage degree of the rear shell and the side surface of the mobile terminal is smaller; the test of drop test shows that: the larger the acceleration value in the process of the mobile terminal colliding with the surface of the collision object is, the larger the falling damage degree of the mobile terminal is, so that the falling damage degree of the mobile terminal can be basically determined according to the maximum acceleration value from the contact moment of the mobile terminal and the surface of the collision object to the process that the mobile terminal is in a static state.
Wherein, the material of the collision object comprises hard material and soft material.
Wherein, the mapping relation of the acceleration value and the hard material and the falling damage is shown in the table 1:
TABLE 1
Wherein g is a gravity acceleration value, and g is 9.8m/s2(ii) a When the falling damage degree of the mobile terminal reaches 100%, the mobile terminal is fallen down.
The mapping relation between the acceleration value and the soft material and the falling damage is shown in the table 2:
TABLE 2
In one embodiment of the application, the mobile terminal determines the material of an impact object impacted by the mobile terminal in a falling event, and the method comprises the following steps:
under the condition that the number of first acceleration values is larger than or equal to a third threshold value, the mobile terminal determines that the material of an impact object impacted by a falling event of the mobile terminal is a hard material, wherein the first acceleration values are larger than or equal to a set acceleration value, and the first acceleration values are detected by the acceleration sensor after the second time period;
under the condition that the number of the second acceleration values is smaller than the third threshold value, the mobile terminal determines that the material of an impact object of the falling event of the mobile terminal is a soft material, the second acceleration values are smaller than the set acceleration values, and the second acceleration values are detected by the acceleration sensor after the second time period.
The third threshold may be user-defined, or may be user-defined by the mobile terminal.
Wherein, the hard material is a material with the hardness of more than 80 degrees, the soft material is a material with the hardness of less than or equal to 80 degrees, the Shore hardness is adopted for measuring the hardness, the Shore hardness represents a standard of the hardness of the material, and a corresponding durometer is proposed and invented by Albert Ferdinand Shore of America in 1920 years.
Wherein the set acceleration value may be a gravitational acceleration value.
For example, as shown in fig. 3, fig. 3 is a graph of a change of an acceleration value during an impact between the mobile terminal and an impact object (from 109ms to 385ms), assuming that the third threshold is 10, and the acceleration value is set to be a gravitational acceleration value, the mobile terminal may determine that the number of acceleration values greater than the gravitational acceleration value is greater than 10 according to fig. 3, and the mobile terminal determines that a material of the impact object impacted by the drop event is a hard material.

step 401: and the mobile terminal detects the acceleration value of the mobile terminal in real time through the acceleration sensor.

if yes, go to step 405.
If not, go to step 403.
Step 405: and at a target moment, the mobile terminal starts the audio component, wherein the target moment is the moment when the acceleration value of the mobile terminal is changed to zero.
Step 406: and the mobile terminal acquires audio information through the audio component.
Step 407: the mobile terminal judges whether the volume of the audio information is greater than or equal to a second threshold value;
if yes, go to step 408.
If not, go to step 406.
Step 408: the mobile terminal determines that the mobile terminal has a falling event.
Step 409: the mobile terminal judges whether the number of first acceleration values is larger than or equal to a third threshold value or not, wherein the first acceleration values are larger than or equal to a set acceleration value, and the first acceleration values are detected by the acceleration sensor after the second time period;
if yes, go to step 410.
If not, no operation is executed.
Step 410: the mobile terminal determines that the collision object impacted by the falling event of the mobile terminal is made of a hard material.
Step 411: the mobile terminal judges whether the number of second acceleration values is smaller than the third threshold value, the second acceleration values are smaller than the set acceleration values, and the second acceleration values are detected by the acceleration sensor after the second time period;
if yes, go to step 412.
If not, no operation is executed.
Step 412: the mobile terminal determines that the material of the collision object impacted by the falling event of the mobile terminal is soft.
Wherein, the steps 409 to 410 and the steps 411 to 412 are parallel.
Step 413: and the mobile terminal determines a target acceleration value, wherein the target acceleration value is the maximum speed value detected by the acceleration sensor after the second time period.
