Mobile terminal, originally falling detection method includes：
S101, mobile terminal is when detecting that the mobile terminal is switched to state of weightlessness by overweight state, described in determination
The First Speed of mobile terminal.
Wherein, for the event of falling of mobile terminal upthrow scene, mobile terminal is fallen based on acceleration identification originally
State detects that adjacent multigroup acceleration value is believed that mobile phone is in close to acceleration of gravity and falls state, so upthrow
In scene, after mobile terminal is detached from human hand, acceleration is acquired by accelerometer, collected acceleration is acceleration of gravity
When, you can it recognizes mobile terminal and is in and fall state, and proceed by and fall timing, however in upthrow scene, it is mobile whole
End is actually still rising, and just starts to fall after rising to peak, so mobile terminal actually falls that over-evaluate should
For the height of peak to ground.
Wherein, the prior art is fallen in recognition strategy, can fall duration calculation falling height according to mobile terminal, fall
The time zero for falling duration is exactly to detect that mobile phone in timing is started when falling state, in upthrow scene, is arrived to calculate
Accurate falling height, at the time of time zero should be that mobile terminal is at the highest notch corresponding, so in order to avoid error,
Detect that mobile terminal is in fall dress state and proceeding by and fall after timing gets and fall duration, need to subtract it is mobile eventually
The duration of end uphill process can just obtain the time of mobile terminal freely falling body.
Wherein, the duration of mobile terminal uphill process can be calculated by initial velocity, and mobile terminal can pass through
The collected acceleration figure of statistical analysis accelerometer obtains in most cases mobile terminal and is detached from corresponding acceleration after human hand
Value and acceleration duration, further calculate the initial velocity to mobile terminal, movement can be calculated after obtaining initial velocity
The duration of terminal uphill process.
Wherein, mobile terminal is in overweight state during being accelerated before being detached from human hand, is detached from mobile terminal
After human hand, it is in state of weightlessness, when detecting that mobile terminal has overweight state to be switched to state of weightlessness, you can calculate movement
The First Speed of terminal, First Speed are speed when mobile terminal is detached from human hand.
S102, the mobile terminal determine the freely falling body time of the mobile terminal according to the First Speed.
Wherein, after obtaining the First Speed of mobile terminal, you can calculate the upthrow duration to mobile terminal, and then calculate
Fall duration under mobile terminal free falling body state.
S103, the mobile terminal calculate the target falling height of the mobile terminal according to the freely falling body time.
Wherein, the state of falling of mobile terminal upthrow scene includes propradation and decline state, and it is certainly to decline state
By falling bodies state, the duration of freely falling body is according to mobile terminal can be calculated the practical falling height of mobile terminal.
As can be seen that in the embodiment of the present application, mobile terminal is detecting that the mobile terminal cut by overweight state first
When being changed to state of weightlessness, the First Speed of the mobile terminal is determined, secondly, determined according to the First Speed described mobile whole
The freely falling body time at end finally calculates the target falling height of the mobile terminal according to the freely falling body time.Due to

History acceleration record it is for statistical analysis can determine First Speed, to be conducive to determine that mobile terminal rises to and falls most
The time of high point.
In a possible example, it includes acceleration direction that the history, which accelerates record,；It is described according to multigroup history
Record is accelerated to determine the First Speed of the mobile terminal, including:Accelerate to obtain in record from multigroup history at least one set of
The upward history of acceleration direction accelerates record；Accelerate the acceleration duration and acceleration value of record according at least one set of history
Determine that the speed average after accelerating is the First Speed.
Wherein, it includes acceleration direction that history, which accelerates record,, can after the multigroup history for getting mobile terminal accelerates record
Accelerate to obtain the upward history acceleration record of at least one set of acceleration direction in record from multigroup history, be added according at least one set of history
Speed recording accelerates duration and acceleration value to determine the average value of the speed after accelerating as First Speed.For example, getting shifting
100 groups of history of dynamic terminal accelerate record, filter out the upward history in continuous 30 groups of directions and accelerate record, are added according to every group of history
Speed recording accelerates duration and acceleration value to determine the speed after accelerating, and 30 groups of history acceleration are recorded being averaged for corresponding speed
Value is stored in mobile terminal as First Speed.
As it can be seen that in this example, First Speed is to accelerate record to count the upward multigroup history in mobile terminal direction
