Direction in component of acceleration, and falling process or the changing value of angle, obtain angle during final and collision on the ground, side
To and position, therefore improve accuracy.
Refer to Fig. 2, the flow chart of the acquisition methods of the drop information that Fig. 2 provides for the embodiment of the present invention two.
The acquisition methods of the drop information of this preferred embodiment, comprising:
Step s201, obtains the acceleration of terminal, and it is pre-conditioned to detect whether this acceleration meets.
For example, terminal obtains acceleration by acceleration transducer, and judges whether terminal is according to this acceleration and fall
Fall state；This is pre-conditioned such as to fall state.Such as, terminal can detect whether acceleration is equal to acceleration of gravity.If
Acceleration is detected and be equal to acceleration of gravity, then judge that terminal meets pre-conditioned, otherwise, it is determined that terminal is unsatisfactory for default bar
Part.This terminal can be the equipment such as mobile phone, panel computer.If terminal judges that it is in falls state, execution step s202.
Otherwise, terminal can be with return to step s201.
In order to improve the accuracy of detection, this acceleration and preset range can be compared by terminal, if this acceleration
Degree is located in preset range, then terminal judges that it is in and falls state, namely this acceleration of this detection whether meet pre-conditioned
Step include:
A, judge that whether this acceleration is located in preset range；
B if it is determined that this acceleration be located at this preset range in it is determined that this acceleration meet pre-conditioned.
For example, terminal judges acceleration whether close to acceleration of gravity if it is decided that this acceleration is close to acceleration of gravity,
Then judge that this terminal is in and fall state.If it is determined that this acceleration keeps off acceleration of gravity, then judge that this terminal is not in
Fall state.This preset range is such as the scope close to acceleration of gravity, specifically can set based on experience value.
Step s202, when this acceleration is detected and meeting pre-conditioned, obtains the component of acceleration before current time.
For example, when terminal judge its be in fall state when, terminal obtains the component of acceleration before falling, and such as terminal obtains
Take its component of acceleration on three directions of x, y, z.
In order to prevent in falling process, important loss of data, terminal can also be when detecting it and falling, will be important
Data backed up, namely described when described acceleration is detected and meeting pre-conditioned, methods described also includes:
D, preset data is backed up.
For example, this preset data is such as the data of default application program, and this default application program is such as by user in advance
Select need carry out the application program of data backup, when terminal detect its be in fall state when, user is pre-selected
The data of application program backed up.Such as when terminal detect its be in fall state when, the number to address list and photo
According to being backed up.
Step s203, obtains according to this component of acceleration and initially falls characteristic information.
For example, terminal determines according to the component of acceleration before falling, the initial value of its direction before falling or angle,
Initially fallen characteristic information.
Step s204, when acceleration is detected and changing, obtains in this change procedure this terminal on preset direction
The variable quantity falling parameter, obtain change component.
For example, when terminal is in and falls state, whether terminal continues to detect its current acceleration by acceleration of gravity
It is changed into 0.Such as, when acceleration is 0 it is possible to determine that terminal is now landed.If a terminal detects that current acceleration is by weight
When power acceleration is changed into 0, it is the variable quantity in three square upwardly directions of x, y, z or angle before 0 that terminal obtains acceleration,
Obtain change component.This falls parameter and includes at least one in direction and angle.
In order to improve the accuracy of detection, current acceleration can be compared by terminal with 0, if both are equal
When, then show that acceleration changes.Namely the step that should detect when acceleration changes includes:
E, detect that whether this acceleration is equal to preset value；
F, when this acceleration be equal to this preset value when it is determined that this acceleration changes.
For example, terminal continues to detect whether its current acceleration is 0.Such as, when acceleration is 0 it is possible to determine that end
End is now landed.
Step s205, initially falls characteristic information according to this and this change component determines this collision characteristic information.
For example, terminal is according to the initial value in the direction before falling or angle, and the direction before landing or angle
The variable quantity of degree determines the information such as angle when terminal and collision on the ground, position and direction.Such as, before this is fallen by terminal
Direction or the initial value of angle and the variable quantity of the direction in falling process or angle carry out corresponding plus-minus and calculate, thus
Obtain terminal and the information such as angle during collision on the ground, position and direction.The position of this collision such as lands for long side, short
While landing, the back side lands, screen lands etc..Angle with ground when the angle of this collision is such as landed for terminal.This collision
Direction such as level fall, vertically fall, tilt to fall etc..
Whether the acquisition methods of the drop information of the present embodiment, by obtaining the acceleration of terminal, and detect this acceleration
Meet pre-conditioned；When this acceleration is detected and meeting pre-conditioned, obtain the component of the acceleration before current time；Root
Obtain according to this component of acceleration and initially fall characteristic information；When acceleration is detected and changing, obtain in this change procedure
The variable quantity falling parameter on preset direction for this terminal, obtains change component；Characteristic information is initially fallen according to this and is somebody's turn to do
Change component determines this collision characteristic information.Due to can according to component of acceleration when falling obtain direction or angle just
Initial value, afterwards further according to the changing value in the direction in falling process or angle, obtains angle during final and collision on the ground, side
To and position, therefore improve treatment effeciency.

Computing, obtains that mobile phone is final and angle during collision on the ground, and the direction fallen according to this angle-determining and position etc..
Such as, mobile phone is landed with lying fashion, x=0 degree, y=0 degree, and falling position is such as screen or the back side, then ties
Close the positive and negative of z value and can determine that screen or the back side land.
With x as axle, mobile phone is landed with standing manner, x=-90 degree, y=0 degree；Falling position is such as downside minor face.
With x as axle, mobile phone is landed in the mode of standing upside down, x=+90 degree, y=0 degree；Falling position is such as upside minor face.
With y as axle, mobile phone is landed with lying fashion before falling, and falls middle rotate counterclockwise upright；X=0 degree, y=+90
Degree；Falling position is such as the long side in left side.
With y as axle, mobile phone is landed with lying fashion before falling, and falls middle rotate counterclockwise upright；X=0, y=-90, fall
It is such as the long side in right side that dropping place is put.
