The first embodiment of the present invention be related to the detection method of falling of mobile terminal a kind of, idiographic flow as shown in figure 1,
It includes：
Step 101, detect the state of mobile terminal in real time by acceleration transducer, and obtain 3-axis acceleration data.
Specifically, the dynamic acceleration that processor is passed back by processing, analysis acceleration transducer, it can be determined that go out to move
The move mode of dynamic terminal.For example：When mobile terminal is with human body slow walking forward together, processor will judge this
When mobile terminal forwardly in microinching；When mobile terminal is quickly run forward together with human body, processor is just
In judging that mobile terminal now is quickly moved forwardly；Similarly, when user takes elevator, processor can also
It is to move or move downward upwards to judge mobile terminal.In actual daily life, the motion conditions of mobile terminal compared with

Step 102, the angle number of degrees of three axles and vertical direction are detected in real time by gyroscope.
Specifically, the angle number of degrees between mobile terminal and horizontal plane can be detected by gyroscope, so as to judge
The degree of deflection of mobile terminal.And in the present embodiment, the function of the angle number of degrees can be detected by gyroscope to detect
The angle number of degrees of three axles and vertical direction as described in step 101.Moreover, proving that present embodiment can by implementing checking
OK.
Step 103, according to the angle number of degrees detected in real time, the 3-axis acceleration data of acquisition are converted into vertical direction
Acceleration.
Specifically, the acceleration on vertical direction is only the data whether real measurement mobile terminal is in state of weightlessness
Foundation, so the acceleration that vertical direction how is obtained by the combination of software and hardware is to judge whether mobile terminal is in fall
The key of state.In the present embodiment, three axles and the angle number of degrees of vertical direction detected in real time according to gyroscope, will be obtained
The 3-axis acceleration data taken are converted into the acceleration of vertical direction, are proven, and present embodiment is feasible.
Step 104, according to the acceleration of vertical direction, judge whether mobile terminal is in and fall state.
Specifically, the acceleration on vertical direction is only the data whether real measurement mobile terminal is in state of weightlessness
Foundation, when mobile terminal, which is in, falls state, mobile terminal must be in state of weightlessness, and state of weightlessness can be by accelerating
Degrees of data is judged.So in the present embodiment, mobile terminal can be judged whether according to the acceleration of vertical direction
In falling state.Such as, (such as preset a ratio when calculating the acceleration for obtaining vertical direction more than a certain threshold value
Acceleration of gravity somewhat a little bit smaller value, 9.5 meter per seconds2) when, judge that mobile terminal is in and fall state.
Compared with prior art, embodiments of the present invention, will by the angle number of degrees detected in real time according to gyroscope
The 3-axis acceleration data of acquisition are converted into the acceleration of vertical direction, and according to the acceleration of vertical direction, can be more accurate
It is true to judge mobile terminal whether in falling state.
What second embodiment of the present invention was related to a kind of mobile terminal falls detection method.Second embodiment is to

Step 203, according to the angle number of degrees detected in real time, the 3-axis acceleration data of acquisition are converted into vertical direction
Acceleration.
Step 204, judge whether the acceleration of vertical direction is more than first threshold, in this way, perform step 205, otherwise, hold
Row step 204.
Specifically, due to the numerical value of acceleration at altitude position either different at different Position Latitudes
Can change, acceleration of gravity can increase with the rise of latitude (acceleration of gravity from equator to two-stage (south poles) constantly
Increase), reduce with the increase of height above sea level.Near under the line, at sea level location, the numerical value of general acceleration of gravity takes 10
Meter per second2。
It is determined that during acceleration rate threshold, two factors of latitude and height above sea level that can be according to residing for mobile terminal are jointly true
It is fixed.In the present embodiment, it is described in detail so that mobile terminal is in equator (i.e. latitude is 0) as an example：First threshold can be with
The height above sea level that position is presently in by obtaining mobile terminal is determined；Wherein, height above sea level obtains mobile whole by global position system GPS

Specifically, when the acceleration for judging vertical direction is more than first threshold, show mobile terminal in mistake
Weight state.But, judge that state is fallen in mobile terminal processing only by the acceleration of vertical direction, may be not accurate enough.When
When mobile terminal is still within state of weightlessness within the relatively long time, judge mobile terminal in fall state can be more
Plus it is accurate.
In actual routine use, mobile terminal is in state of weightlessness, and to time typically very short, the mistake for falling face
Journey may can just be completed in 1 second.In order to quickly judge and avoid the generation of erroneous judgement, Second Threshold can be pre-
It is set to 0.8 second, when the duration that the acceleration of vertical direction is more than first threshold being more than default 0.8 second, is judged as movement
Terminal, which is in, falls state.But present embodiment should not be as limit, those skilled in the art can be clever as the case may be
It is living to set.
Step 206, judge that mobile terminal is in and fall state.
That is, when the duration that the acceleration for judging vertical direction is more than first threshold is more than default Second Threshold
When, processor will judge that mobile terminal is in and fall state.
