At least two inertial sensors 101.
Here, mobile terminal include inertial sensor 1 ..., n, wherein n is integer more than or equal to 2.
Inertial sensor 101 includes but is not limited to that acceleration transducer, gyro sensor, acceleration and gyroscope two close
One sensor.Inertial sensor 101 is used to acquire the inertia mobile message of mobile terminal, such as acceleration information, inclination information, punching
Hit information, vibration information, rotation information and multifreedom motion information etc..
Processor 102, for obtain the application scenarios of the mobile terminal to the performance requirement of inertial sensor 101 and/

The performance requirement of device 101 controls the operating mode of at least two inertial sensors 101, and/or according at least two
The working condition of inertial sensor 101 judges the disabled status of at least two inertial sensors 101, and according to the mistake
Effect situation coordinates the operating mode between at least two inertial sensors 101.
Here, processor 102 can be controlled according to the application scenarios of mobile terminal to the performance requirement of inertial sensor 101
It makes each inertial sensor 101 and is in different working modes, can also be coordinated each according to the working condition of inertial sensor 101
The operating mode of a inertial sensor 101.
The mobile terminal of the embodiment of the present invention can be according to mobile terminal by the way that at least two inertial sensors 101 are arranged
Application scenarios control each inertial sensor 101 and be in different working modes, to meet between performance, power consumption and reliability
Balance；Also it can coordinate the operating mode of each inertial sensor 101 according to the working condition of inertial sensor 101, such as work as certain
When one inertial sensor 101 fails, coordinate other inertial sensor 101 and work normally, is made with coping with mobile terminal in production
Make with the higher situation of inertial sensor crash rate in user's use, guarantee the normal use of user；Improve practicability and intelligence
Energyization, the user experience is improved.
Wherein, processor 102 can also obtain the data of the acquisition of inertial sensor 101, and inertial sensor 101 is acquired
Data carry out calculation process according to predetermined manner, to issue control instruction according to operation result, refer to mobile terminal according to control
It enables and carries out corresponding operation.
For example, processor 102 can carry out calculation process to the acceleration information that inertial sensor 101 acquires, screen is obtained
Inclined angle is shown displayed across or vertically displaying instruction to issue control screen；It can also be to inertial sensor 101
The acceleration information of acquisition carries out calculation process, judges the movement whether terminal is made a move, to issue control movement
The pedometer of terminal carries out the instruction of step counting.
Specifically, mobile terminal such as may include two acceleration transducers, an acceleration transducer and one may also comprise
A acceleration and the two-in-one sensor of gyroscope.Wherein since acceleration and the two-in-one sensor performance of gyroscope are more preferable, power consumption
It is bigger preferably to be balanced between acceleration transducer cooperation availability and power consumption.
Specifically, the operating mode of the inertial sensor 101 may include the difference corresponding to the inertial sensor 101
Multiple works of power consumption or the different output data rates (ODR, Output Data Rates) corresponding to the inertial sensor 101
Operation mode.
At this point, can be each to control according to the application scenarios of mobile terminal and/or the working condition of inertial sensor 101
Inertial sensor 101 is in the operating mode of different power consumption or different output data rates, to meet the application scenarios of mobile terminal
Performance requirement, and improve the reliability of mobile terminal Inertial Sensor System.
Wherein the operating mode of inertial sensor 101 is such as can include: high performance operation mode, normal operating mode, low function
Work consuming operation mode and ultra low power mode of operation etc..
The different working modes of sensor can be also defined in practical application according to specific Choice of Sensors.
Further, the different application scene of mobile terminal can be defined based on the performance requirement to inertial sensor 101,
Such as it can be defined as follows application scenarios:
Scene of game: needing the high performance properties of inertial sensor, lower to power consumption requirements；
Screen turning transition scape: it is not high to the performance requirement of inertial sensor, it is lower to power consumption requirements；
Sleep scene: inertial sensor is needed to be in real-time always-on state, it is desirable that low-power consumption；
Super power saving application scenarios: inertial sensor work is not needed, inertial sensor can be closed.
Wherein the inertial sensor 101 of different model usually has different power consumption and performance.It at this time can be according to shifting
Terminal current application scene is moved to the performance requirement of inertial sensor 101, to coordinate the different operating of each inertial sensor 101
Mode, so that current application scene and the power consumption and performance of inertial sensor 101 match, the work effect being optimal
Fruit meets the balance between performance, power consumption and reliability.
Assuming that mobile terminal includes two acceleration transducers, and at same ODR, acceleration transducer 1 and acceleration
Degree sensor 2 is compared to there is preferable power consumption to show, although and the power consumption compared with acceleration transducer 1 of acceleration transducer 2 is higher
But sampling sensitivity is higher, corresponding performance is also relatively preferable.
When mobile terminal is in scene of game, controllable acceleration transducer 2 is in high performance operation mode, and controls
Acceleration transducer 1 is in super low-power consumption mode, only uses the data of the acquisition of acceleration transducer 2.Due to acceleration transducer 2
Sampling sensitivity is high, and corresponding performance also relatively preferably, therefore can satisfy scene of game to the high performance demands of inertial sensor,
Keep scene of game operation more smooth, so that the user experience is improved.
When mobile terminal is in sleep scene and needs the real-time inertia for sensing mobile terminal mobile, acceleration can control
Sensor 1 is in low-power consumption mode and acquires data, and controls acceleration transducer 2 and be in super low-power consumption mode and do not acquire number
According to.Since acceleration transducer 1 is showed with preferable power consumption, the power consumption of mobile terminal under sleep scene can reduce,
To save the energy of mobile terminal, duration performance is improved.
In this way, can have high performance properties, higher sensitivity in user's normal use mobile terminal, while moving
When dynamic terminal sleep mode under lowest power consumption real-time data collection, reduce the energy of mobile terminal consumption.
Preferably, at least two inertial sensors 101 can be respectively arranged at the different zones of the mobile terminal.
At this point, at least two inertial sensors 101 are in the layout of the different zones of mobile terminal, avoid mobile terminal and fall
Or when by external impact, because (such as jump in temperature or fatigue make for the same mechanical stress or other factors that act on mobile terminal
With) simultaneously destroy multiple inertial sensors 101, lead to multiple inertial sensors 101 while failing the case where, improve reliability
Redundancy.
Assuming that mobile terminal includes two 3-axis acceleration sensors, as shown in Fig. 2, can put two acceleration transducers
It is placed in the different stress positions of Mobile terminal main board.Further, the first acceleration transducer 201 and the second acceleration can be made to pass
The phase same-action axis (X/Y/Z axis) of sensor 202 is respectively directed to different predetermined directions, reduces the identical of two acceleration transducers
The probability that axis fails simultaneously is acted on, can also combine the effect that two acceleration transducers do not fail as far as possible when failing
The function of axis realization three-axis sensor.
Specifically, processor 102 can judge mobile terminal according to the working condition of the inertial sensor 101 of mobile terminal
Inertial sensor 101 disabled status；Then according to disabled status, the operating mode to each inertial sensor 101 is issued
Control instruction.
At this point, processor 102 can recognize specific disabled status, and coordinate other when the failure of a certain inertial sensor 101
Inertial sensor 101 guarantees the normal detection function of the inertial data of mobile terminal.
Further, processor 102 can with one of the communication failure of inertial sensor 101, inertial sensor 101 or
Multiple axis output datas be greater than the duration of invalid value one of the first preset threshold T1 and/or inertial sensor 101 or
When multiple axis are greater than the second preset threshold T2 without the duration of output data, judge that disabled status occurs in inertial sensor 101,
Otherwise judge that inertial sensor 101 does not occur disabled status.
Wherein for acceleration transducer, if one or more axis output datas of acceleration transducer are more than acceleration threshold
Value G, and the duration is more than T1, then can determine whether that disabled status occurs in the acceleration transducer.
For example, the range of acceleration transducer is set as +/- 2g (sign expression difference usually in handheld mobile device
Acceleration direction), when the output data that processor 102 reads a certain axis of sensor is 2500mg always, and the duration
When more than T1, then it can determine whether that the acceleration transducer fails.
Wherein, the first preset threshold T1, the second preset threshold T2 and acceleration rate threshold G can be carried out according to practical situations
It adjusts.
Further, processor 102 can issue control and not fail when disabled status occurs in part inertial sensor 101
101 detection data of inertial sensor instruction；When whole inertial sensors 101 disabled status occur, obtain each used
Property sensor 101 in the axis output data that does not fail, and judge whether the axis output data got includes multiple predetermined directions
On detection data；If the axis output data got includes the detection data on multiple predetermined directions, issues control and obtain
The corresponding inertial sensor 101 of the axis output data got continues to test the instruction of the data in respective shaft；If having not been obtained not
The axis output data of failure or the axis output data got do not include the detection data on multiple predetermined directions, then issue control
Make the instruction that whole inertial sensors 101 stop detection data.
At this point, failing in only part inertial sensor 101, then other inertial sensors 101 can control to work normally, protects
Demonstrate,prove the normal detection function of mobile terminal；When whole inertial sensors 101 fail, then inertial sensor is combined as far as possible
101 number of axle evidences not failed, to realize the normal detection function of mobile terminal as far as possible.
Assuming that mobile terminal includes two 3-axis acceleration sensors.When the failure of a certain acceleration transducer, processor
102 can close the acceleration transducer power supply of failure or the acceleration transducer of control failure is in super low-power consumption mode, and control
It makes the acceleration transducer not failed to work normally, executes single-sensor system at this time, guarantee that mobile terminal normally detects function
Energy.
When two acceleration transducers have a certain or multiaxis to fail, combine in two acceleration transducers as far as possible not
The effect number of axle evidence of failure guarantees mobile terminal normal function.Such as the X1 axis failure of acceleration transducer 1, Y1, Z1 axis are just
Often；The X2 axis of acceleration transducer 2 is normal, the failure of Y2, Z2 axis, at this point it is possible to realize that three axis pass by combination Y1, Z1, X2 axis
Sensor normal function.
Factually show when two acceleration transducers all fail and cannot combine the effect number of axle not failed in two sensors
When three-axis sensor function, processor 102 simultaneously closes off two acceleration transducers of two acceleration transducer power supplys or control
It is in super low-power consumption mode.
Very big to customer impact after single inertial sensor failure, especially horizontal/vertical screen is converted, camera shooting picture overturning, game control
The basic functions such as system are unable to normal use.The mobile terminal of the embodiment of the present invention is very big by using more Inertial Sensor Systems
Ground improves reliability.If the crash rate of single Inertial Sensor System is 100ppm, and double Inertial Sensor Systems can to the greatest extent can
It can guarantee that above-mentioned basic function is normal, crash rate can theoretically be reduced to 0.01ppm.In addition, between multiple inertial sensors
It is able to carry out mutually calibration and touches positioning, improve the accuracy of Data Detection.
Preferably, the mobile terminal of the embodiment of the present invention can also include:
At least one processor 103 is connect with the processor 102, is transmitted for receiving and storing the processor 102
Data.
Here, memory 103 can be separate storage chip, can also be integrated in inside processor 102, be not limited thereto.
At this point, facilitating the storage of data in processor 102 by memory 103, the operation efficiency of processor is improved.
The mobile terminal of the embodiment of the present invention, multiple inertial sensors of use are in the layout of the different zones of mobile terminal,
It avoids acting on the same mechanical stress of mobile terminal and other factors while damaging multiple inertial sensors, there is higher reliability
Redundancy；Processor can cooperate with multiple inertial sensors to work in different operating modes, optimize mobile terminal performance and power consumption
Performance；System can be known automatically when the factors such as using a certain inertial sensor to be caused to fail by mechanical stress, jump in temperature or fatigue
Other failure conditions, and other intelligent coordinated inertial sensors work normally, and do not influence user and use mobile terminal basic function.

Sensor is in the operating mode of different power consumption or different output data rates.
Wherein the operating mode of inertial sensor is such as can include: high performance operation mode, normal operating mode, low-power consumption work
Operation mode and ultra low power mode of operation etc..
The different working modes of sensor can be also defined in practical application according to specific Choice of Sensors.
Further, the different application scene of mobile terminal, example can be defined based on the performance requirement to inertial sensor
It such as can be defined as follows application scenarios:
Scene of game: needing the high performance properties of inertial sensor, lower to power consumption requirements；
Screen turning transition scape: it is not high to the performance requirement of inertial sensor, it is lower to power consumption requirements；
Sleep scene: inertial sensor is needed to be in real-time always-on state, it is desirable that low-power consumption；
Super power saving application scenarios: inertial sensor work is not needed, inertial sensor can be closed.
Wherein the inertial sensor of different model usually has different power consumption and performance.It at this time can be according to mobile whole
Hold current application scene to the performance requirement of inertial sensor, to coordinate the different working modes of each inertial sensor, so that
The power consumption and performance of current application scene and inertial sensor match, and the working effect being optimal meets performance, function
Balance between consumption and reliability.
Assuming that mobile terminal includes two acceleration transducers, and at same ODR, acceleration transducer 1 and acceleration
Degree sensor 2 is compared to there is preferable power consumption to show, although and the power consumption compared with acceleration transducer 1 of acceleration transducer 2 is higher
But sampling sensitivity is higher, corresponding performance is also relatively preferable.
When mobile terminal is in scene of game, controllable acceleration transducer 2 is in high performance operation mode, and controls
Acceleration transducer 1 is in super low-power consumption mode, only uses the data of the acquisition of acceleration transducer 2.Due to acceleration transducer 2
Sampling sensitivity is high, and corresponding performance also relatively preferably, therefore can satisfy scene of game to the high performance demands of inertial sensor,
Keep scene of game operation more smooth, so that the user experience is improved.
When mobile terminal is in sleep scene and needs the real-time inertia for sensing mobile terminal mobile, acceleration can control
Sensor 1 is in low-power consumption mode and acquires data, and controls acceleration transducer 2 and be in super low-power consumption mode and do not acquire number
According to.Since acceleration transducer 1 is showed with preferable power consumption, the power consumption of mobile terminal under sleep scene can reduce,
To save the energy of mobile terminal, duration performance is improved.
Preferably, at least two inertial sensors can be respectively arranged at the different zones of the mobile terminal.
At this point, at least two inertial sensors are in the layout of the different zones of mobile terminal, avoid mobile terminal fall or
When by external impact, because acting on the same mechanical stress or other factors of mobile terminal (such as jump in temperature or fatigue use)
The case where destroying multiple inertial sensors simultaneously, lead to multiple inertial sensors while failing, improves reliability redundancy.
Assuming that mobile terminal includes two 3-axis acceleration sensors, as shown in Fig. 2, can put two acceleration transducers
It is placed in the different stress positions of Mobile terminal main board.Further, the phase of acceleration transducer 1 with acceleration transducer 2 can be made
Same-action axis (X/Y/Z axis) is respectively directed to different predetermined directions, reduces the phase same-action axis of two acceleration transducers simultaneously
The probability of failure can also combine the effect axis that two acceleration transducers do not fail as far as possible when failing and realize three axis
The function of sensor.
Further, described that at least two each inertia biographies are coordinated according to the disabled status in above-mentioned steps 503
The step of operating mode between sensor may include:
Step 5031, when disabled status occurs in inertial sensor in part, the inertial sensor testing number not failed is controlled
According to；
Step 5032, it when whole inertial sensors disabled status occur, obtains and does not fail in each inertial sensor
Axis output data, and judge whether the axis output data that gets includes detection data on multiple predetermined directions；
Step 5033, it if the axis output data got includes the detection data on multiple predetermined directions, controls and obtains
The corresponding inertial sensor of axis output data got continues to test the data in respective shaft；
Step 5034, if the axis output data not failed has not been obtained or the axis output data that gets do not include it is multiple
Detection data on predetermined direction then controls whole inertial sensors and stops detection data.
At this point, failing in only part inertial sensor, then other inertial sensors can control to work normally, guarantees movement
The normal detection function of terminal；When whole inertial sensors fail, then combination inertial sensor as far as possible does not fail
Number of axle evidence, to realize the normal detection function of mobile terminal as far as possible.
Assuming that mobile terminal includes two 3-axis acceleration sensors.When the failure of a certain acceleration transducer, can close
The acceleration transducer power supply of failure or the acceleration transducer of control failure be in super low-power consumption mode, and control is not failed
Acceleration transducer works normally, and executes single-sensor system at this time, guarantees the normal detection function of mobile terminal.
When two acceleration transducers have a certain or multiaxis to fail, combine in two acceleration transducers as far as possible not
The effect number of axle evidence of failure guarantees mobile terminal normal function.Such as the X1 axis failure of acceleration transducer 1, Y1, Z1 axis are just
Often；The X2 axis of acceleration transducer 2 is normal, the failure of Y2, Z2 axis, at this point it is possible to realize that three axis pass by combination Y1, Z1, X2 axis
Sensor normal function.
Factually show when two acceleration transducers all fail and cannot combine the effect number of axle not failed in two sensors
When three-axis sensor function, simultaneously close off two acceleration transducer power supplys or control two acceleration transducers be in it is ultralow
Power consumption mode.
Further, in above-mentioned steps 503, the working condition according at least two inertial sensors, judgement
The step of disabled status of at least two inertial sensors may include:
Step 5035, defeated with one or more axis of the communication failure of the inertial sensor, the inertial sensor
Data are to be greater than one or more axis of the first preset threshold T1 and/or the inertial sensor duration of invalid value out
When the duration of no output data is greater than the second preset threshold T2, judge that disabled status occurs in the inertial sensor, otherwise
Judge that the inertial sensor does not occur disabled status.
Wherein for acceleration transducer, if one or more axis output datas of acceleration transducer are more than acceleration threshold
Value G, and the duration is more than T1, then can determine whether that disabled status occurs in the acceleration transducer.
For example, the range of acceleration transducer is set as +/- 2g (sign expression difference usually in handheld mobile device
Acceleration direction), when the output data for reading a certain axis of sensor is 2500mg always, and the duration is more than T1,
It then can determine whether that the acceleration transducer fails.
Wherein, the first preset threshold T1, the second preset threshold T2 and acceleration rate threshold G can be carried out according to practical situations
It adjusts.

The double Inertial Sensor Systems for crossing the method for the present invention processing can guarantee that above-mentioned basic function is normal as far as possible, and crash rate is theoretically
0.01ppm can be reduced to.
Preferably, the processing method can also include:
Step 504, obtain the data of inertial sensor acquisition, and to the data of inertial sensor acquisition according to
Predetermined manner carries out calculation process.Corresponding operation is carried out to control mobile terminal according to operation result.
For example, calculation process can be carried out to the acceleration information that inertial sensor acquires, the angle of screen inclination is obtained, from
And it controls screen and is shown displayed across or vertically displaying；The acceleration information that inertial sensor acquires can also be carried out at operation
