It describes in detail below to the embodiment of the present application.
Referring to Fig. 1, figure is a kind of flow diagram falling detection method provided by the embodiments of the present application, this method packet It includes:
Step 101:Mobile terminal detects the acceleration value of the mobile terminal by the acceleration transducer in real time.
Wherein, if mobile terminal determines that acceleration value in the X-axis direction is a by acceleration transducerx, in Y-axis side Upward acceleration value is ayAcceleration value in the Z-axis direction is az, then the acceleration value of the mobile terminal be
Step 102:The acceleration of the mobile terminal is consecutively detected within the first period in the acceleration transducer Value is greater than or equal to first threshold, and the acceleration transducer is consecutively detected adding for the mobile terminal within the second period In the case that velocity amplitude is less than or equal to the first threshold, mobile terminal determines that the mobile terminal falls event, institute Stated for the first period earlier than second period, and first period is adjacent with second period.
Under normal conditions, when mobile terminal is supported there are thing (such as human hand, desk etc.), mobile terminal passes through acceleration Degree sensor detects that mobile terminal is only affected by gravity, and mobile terminal determines the acceleration in X-axis and Y-axis both direction Angle value is 0, and acceleration value in the Z-axis direction is gravity acceleration value, in this case the acceleration value of the mobile terminal For gravity acceleration value;It is mobile when mobile terminal does not have thing support (for example, mobile terminal from fall on hand or on desk) Terminal is in free falling body state, and acceleration transducer is also at free falling body state, acceleration transducer and mobile terminal phase To static, mobile terminal detects mobile terminal not by outer force effect by acceleration transducer, and mobile terminal is determined in X-axis, Y Acceleration value on three directions of axis and Z axis is 0, and the acceleration value of the mobile terminal is zero in this case.
Under normal conditions, when mobile terminal falls from human hand or desk, the acceleration value of mobile terminal can be from gravity Acceleration value becomes cancellation;It is in falling process in mobile terminal, the acceleration value holding zero of mobile terminal is constant;It is mobile whole The acceleration value at end becomes the process that cancellation is a gradual change from gravity acceleration value, and the acceleration value during being somebody's turn to do can pass through Detection obtains the acceleration transducer of mobile terminal in real time.
Wherein, first threshold can be user-defined, can also be that mobile terminal is customized, first threshold is more than Zero and be less than gravity acceleration value.
Wherein, the corresponding acceleration value of termination timing node of the first period is corresponding with the initial time node of the second period Acceleration value it is identical.
For example, as illustrated in fig. 2, it is assumed that first threshold is 5m/s2, in the first period (t1-t2) interior mobile terminal plus Velocity amplitude is gradually decrease to 5m/s from gravity acceleration value2(meet within the first period the acceleration value of mobile terminal be more than or Equal to first threshold), in the second period (t2-t3) interior mobile terminal acceleration value from 5m/s2It is decreased to zero and keeps zero to preset Duration (acceleration value for meeting the mobile terminal within the second period is less than or equal to first threshold), preset duration t4With t3's Event is fallen in difference, mobile terminal determination.
As it can be seen that in the embodiment of the present application, when mobile terminal falls event, the acceleration value of mobile terminal can be from Gravity acceleration value is reduced to zero, and the variation of acceleration value is the process of a gradual change, and the acceleration value in the progressive formation Can degree of being accelerated sensor detect.The application is greater than or equal to first by the acceleration value that the first period was consecutively detected Threshold value, the acceleration value that the second period was consecutively detected determine that the acceleration value of mobile terminal is gradually less than or equal to first threshold Become, and then determines that mobile terminal falls event.
In the embodiment of the application, the sum of the duration of the duration of first period and second period be more than or Equal to the 4th threshold value.
Wherein, the duration of the first period can be equal with the duration of the second period, can not also be equal.
Wherein, the 4th threshold value can be user-defined, can also be that mobile terminal is customized.
Wherein, the second period was that the acceleration value of mobile terminal is decreased to zero from first threshold and keeps acceleration value be zero Preset duration corresponding period, preset duration can be user-defined, can also be that mobile terminal is customized.
Under normal conditions, when mobile terminal is fallen to (such as less than or equal to 15cm) on desk from a certain height, this The time that process needs is very short, and the influence to mobile terminal almost can be ignored, and not be denoted as the event of falling;When mobile whole When end is fallen to from object height range (such as 80cm-120cm) on desk, the time that this process needs is relatively long and right The influence of mobile terminal is denoted as the event of falling than more serious.
As it can be seen that in the embodiment of the present application, the sum of duration of the duration of the first period and the second period is greater than or equal to the Four threshold values can exclude to fall to collision object surface to mobile terminal from a certain height (such as less than or equal to 15cm) in this way Influence almost to ignore non-falls event.
In the embodiment of the application, mobile terminal further includes audio component, and the determination mobile terminal occurs Before falling event, the method further includes:
In object time, mobile terminal opens the audio component, and the object time is the acceleration of the mobile terminal At the time of angle value becomes cancellation;
Mobile terminal acquires audio-frequency information by the audio component;
Mobile terminal determines that the volume of the audio-frequency information is greater than or equal to second threshold.
Wherein, second threshold is for characterizing the minimal volume that mobile terminal falls event;Second threshold can be used Family is customized, can also be that mobile terminal is customized.
It specifically, in some cases may be to movement if mobile terminal is kept for the time that acceleration value is zero longer The influence of terminal can also be to ignore, for example user throws away mobile terminal to relatively soft object (such as quilt etc.), Therefore it also needs to further determine that mobile terminal in that case and collides sound size when object is hit, if excessive expression Mobile terminal is collided with harder collision object, is affected to mobile terminal, is denoted as the event of falling;Otherwise, it is not denoted as and falls Fall event.
