Embodiment one
Below in conjunction with Fig. 1, Fig. 1 is a kind of flow chart of mobile terminal locating method provided by the embodiments of the present application, tool
Body includes the following steps：
S101：The real time kinematics information for receiving motion sensor acquisition, mobile terminal is determined according to real time kinematics information
Motion state；
This step is intended to determine what it was according to the real time kinematics information of the collected mobile terminal of motion sensor
Motion state.Wherein, motion sensor refers to all sensors that can collect movable information, such as 3 axle acceleration sensors
(also referred to as 3 axis accelerometers), gyroscope, geomagnetic sensor etc..
Acceleration transducer as the sensor that can measure acceleration, usually by mass block, damper, elastic element,
The part such as sensing element and suitable tune circuit forms.Acceleration transducer is in accelerator, by inertia force suffered by mass block
Measurement, utilize Newton's second law obtain acceleration value, according to the difference of sensor sensing element, common acceleration sensing
Device includes condenser type, inductance type, strain-type, pressure resistance type, piezoelectric type etc.；Gyroscope is called angular-rate sensor, is different from acceleration
Spend the acceleration value of sensor measurement, the rotational angular velocity when physical quantity that gyroscope measures is deflection, inclination, in some movements
In the smaller action of amplitude, only complete space 3D accurately can not be measured or be reconstructed with acceleration transducer and act, because plus
Velocity sensor can only detect axial line movement and not detect the action of rotation, therefore gyroscope can be to the physics of missing
Amount carries out good additional survey, to the action message that more accurately reduction and judgement occur；Geomagnetic sensor is a kind of
Using using earth magnetic field ferromagnetic object by when variation come the sensor that is detected, usually passed by anisotropic magnetoresistive
Sensor is made of thin film alloys (permalloy), and using current-carrying magnetic material, resistance characteristic will change in the presence of external magnetic field
Basic principle carry out changes of magnetic field measurement, be widely used in vehicle location and stationary vehicle calendar scheduling field.
According to the description of the above-mentioned principle to several motion sensors and functional information, it can be found that each is different types of
Motion sensor can collect movable information in a certain respect, and the movable information of different aspect can carry out complementation,
It is more accurate to motion state to integrate the different types of movable information realization that multi-motion sensor collects respectively
Judgement, in actual use, according to the specifically used scene for the mobile terminal for being equipped with the motion sensor and the use
To the requirement of determining motion state precision under scene, a variety of different motion sensors can be flexibly selected to realize purpose, herein
It is not especially limited.
Wherein, motion state can be broadly divided into static, active movement and passive movement：Stationary state shows to be equipped with the fortune
The mobile terminal of dynamic sensor remains static；Active movement state indicates that the mobile terminal such as is in away or runs at the active movements
State refers to further carrying the user of the mobile terminal active movements state such as to be in away or run in most cases；
Passive movement state indicates the mobile terminal to be under the carrying of a carrier for possessing higher motion speed and carries out passive movement
State (such as carry the mobile terminal user ride bicycle or ride in an automobile).Active movement state and passive movement
One more apparent distinctive points of state are larger for the motion amplitude under active motion state, and the fortune under passive movement state
Dynamic amplitude is then relatively small, that is, is in one compared under smooth motion state.
According to above to the classification of motion state, it can be seen that the mobile device under different motion state is accurate to carrying out
The demand of positioning differs, by taking stationary state as an example：When mobile terminal remains static through the determination of real time kinematics information, explanation
The mobile terminal at this time may by be lain in somewhere or carry the mobile terminal user be still in some ground
Side does not need that locating module is normally opened continual to be accurately positioned the shifting substantially at this time in addition to the specific demand under special scene
The location information of dynamic terminal, in some instances it may even be possible to all be not required to open the locating module, therefore can be fixed by reducing this under stationary condition
The location frequency of position module is even switched off the mode of locating module to reduce the power consumption of the locating module, reduces mobile device
Power consumption.
Suitable locating module occupation mode will be provided respectively to different motion states below.
S102：The duration of remains stationary state is calculated, and enables locating module pair when duration meets static locating rule
Mobile terminal is positioned；
This step is established on the basis of determining that the mobile terminal remains static according to real time kinematics information, it is intended to will
Whether the duration under remaining static is used as enables the pinpoint basis for estimation of locating module progress.It remains static down
Mobile terminal, mean that it need not work in most cases, that is, be in idle state, in idle state
Mobile terminal is usually only necessary to system bottom service and is in standby, without being accurately positioned, also just without opening
Locating module.But mobile terminal is judged as in idle state being inaccurate once into stationary state, how to weigh it
It is exactly the duration of the mobile terminal remains stationary state whether to be in an important parameter of idle state.
Specifically, the static duration threshold value of a suitable size can be pre-set, whenever the mobile terminal remains static
The duration of state, which reaches the static duration threshold value and just enables one-time positioning module, positions the mobile device, i.e., is protected always
Hold it is static in the state of, locating module is enabled with prefixed time interval, is only changed to original locating module normally open
It periodically enables once, is shut off the locating module after completing to position, can effectively reduce locating module institute under static state
The electricity of consumption.
Further, passing through a certain number of time intervals, and the mobile terminal keeps quiet in each time interval
Only when state, preset static duration threshold value before can also being suitably turned up, such as 5 will be transferred on originally set 3 minutes
Minute, in the gradual enabling time for deepening to gradually reduce locating module during the determining mobile terminal is in idle state
Number, further to reduce the electricity spent by locating module.Further, when from determining the mobile terminal for the first time
When stationary state, until when the total duration of the stationary state currently being kept to be more than a larger duration, this can be confirmed
Mobile terminal is in idle state really, therefore locating module can be closed within the time later, no longer enables, until basis
The collected real-time motion data of motion sensor determines that the mobile terminal breaks the stationary state kept before, before breaking
Stationary state after, need to redefine the newest motion state of the mobile terminal.
It should be noted that when raising preset quiescent time threshold value, the minimum adjustment raised every time can also be set
Unit is reached the standard grade with adjustment number or quiescent time upper threshold is especially existed with keeping the positive locating function of the locating module
When locating module is used separately as tracker (tracking underage child position), it is also required to every certain even at stationary state
Time determines the position of the tracker.
S103：The active displacement of mobile terminal is calculated, and enables and determines when active displacement meets active movement locating rule
Position module positions mobile terminal；
This step establish according to real time kinematics information determine the mobile terminal have the initiative motion state on the basis of, purport
Using under the motion state that has the initiative the mobile terminal occur active displacement as whether enable locating module carry out accurately calmly
The basis for estimation of position.
Why select displacement as whether the basis for estimation that locating module positions mobile terminal is enabled, be because
For distance, displacement it is relatively reliable (can be used when more being partial to show movement locus path as judge according to
According to), why need to position, be the change in location since it is desired that monitoring objective, is turning back, under the movements such as pitch of the laps, with the time
Increase, the distance of mobile terminal can be continuously increased, but (be rolled over when the diameter of the one way distance and pitch of the laps turned back is smaller
It is smaller to return the region moved with pitch of the laps), change in displacement unobvious do not change even, i.e., when the active movement shape of the mobile terminal
It is that need not carry out accurately determining when state is happened in a smaller region (such as user holds mobile phone and persistently walks about at home)
Position, therefore, to save the enabling number and power consumption of locating module as far as possible, whether the application selects using displacement as opening
The basis for estimation that mobile terminal is positioned with locating module, and can by adjust active displacement threshold value size filtering compared with
The active movement and be retained in the active movement occurred in wide range that a small range occurs.
Therefore the comparison parameter in this case in the active movement locating rule may be selected by and active displacement pair
The active displacement threshold value answered just enables only when the size of the active displacement of the mobile terminal is consistent with the active displacement threshold value
One-time positioning module completes positioning.
Wherein, in the calculating process of the active displacement, traditional number fed back to based on acceleration transducer may be used
According to inertia estimation is carried out or the data based on motion sensor feedback carry out the mode of composite calulation, but since motion sensor is adopted
The data collected back are all transient datas one by one, practical during the estimation of conscientious inertia and composite calulation to also need to be accumulated
Point, i.e., acceleration obtains speed by primary integral, and speed obtains displacement using primary integral, is limited to sensor acquisition frequency
Rate so that the size of active displacement obtained after integrating twice differs larger with the size of real displacement, therefore to make
The active displacement being calculated levels off to real displacement as far as possible, can also utilize the meter step ability and posture of motion sensor
Resolving ability, i.e., the travel that is calculated in a manner of step-length × step number under each athletic posture (in Fig. 5,
OA1, A1A2, A2A3 and A3A are the travel under four different motion postures respectively), final mode for example shown in fig. 5
Displacement (being OA in Fig. 5) is calculated in conjunction with the definition of displacement.Wherein, step-length can be advance according to the user of the mobile terminal
Input, but the biological characteristic inputted unavoidably is not accurate enough, and final active displacement meter is caused to calculate mistake, it can also be to according to advance
The step-length (basic step-length) of input combines the biological characteristic of user and exercise habit to be modified, to obtain one closer to true
Actual step size.
A kind of step-length correcting mode including but not limited to can be found in table 1：
1 step-length amendment of table corresponds to table
| Step number (nums) per minute | Actual step size |
| Less than or equal to 80 | 0.4*BSL |
| (80 90] | 0.5*BSL |
| (90 120] | 0.007*(nums-90)^2+0.5*BSL |
| (120 162] | 0.02*(nums-120)^2+0.55*BSL |
| (162 180] | -0.02*(nums-180)^2+BSL |
| More than or equal to 180 | 0.95*BSL |
In table 1, BSL (basic step-length)=gender parameter (man is 0.85, female 0.8) * heights.
One is being obtained close to after true step-length, so that it may in terms of combining easily step number calculate each
Horizontal attitude angleUnder travel (OA1, A1A2, A2A3 and A3A), eventually byIt is calculated
Active displacement OA, whereinOther parameters can and so on calculate
It arrives, does not repeat one by one herein.
Further, the upper primary time for enabling locating module and being positioned in the case where the mobile terminal keeps active state
When long away from current duration, usually illustrate that previously positioned active displacement threshold value is less suitable, although causing the mobile terminal
Have the initiative motion state, but its active displacement is not up to standard, it is contemplated that the user for carrying the locating module may be a fortune
The limited underage child of kinetic force and scope of activities, can preset active displacement threshold value before downward appropriate so that adjusting
Active displacement threshold value after whole can carry out more sensitive detection and positioning to the active movement state of underage child.
S104：The travel speed of target device is calculated, and is determined and travel speed according to passive movement state locating rule
Corresponding location frequency, and mobile terminal is positioned by location frequency control locating module.
This step is established on the basis of determining that the mobile terminal is in passive movement state according to real time kinematics information, purport
In the case where that will be in passive movement state, alternatively great location frequency uses locating module to the travel speed of the mobile terminal
Selection gist.
It is different from the mode that S102 and S103 uses locating module, due under passive movement state, generally possessing larger
Travel speed, therefore do not fit through some threshold values come do single enable locating module judgement because in such movement shape
It is bound to more frequently be accurately positioned mobile terminal position by locating module under state, therefore this step passes through
A location frequency corresponding with travel speed is determined, so that locating module is positioned under the location frequency, usually
In the case of location frequency be positively correlated with travel speed because travel speed means that more greatly the mobile terminal is real in the unit interval
The physical length that border is passed through is bigger, excessive per the physical distance that positions twice to prevent, and should be reduced by adjusting location frequency
Per the time interval positioned twice.For example, using upper frequency request positioning when high-speed motion, using intermittent request when middling speed
Positioning, using larger intermittent request positioning when low speed.
Wherein, the acceleration information that the calculation generally use of the travel speed is fed back to according to acceleration transducer into
The mode of row integral is calculated, and certainly, is also not excluded for confidence level is calculated using other similar modes slightly lower or higher
Travel speed herein and is not specifically limited.
Further, can be with the enabling information of persistent collection locating module, it may include enable number, enable every time when
Between, the parameters such as the power consumption that enables every time, and summarized generation positioning daily record, on the one hand later stage retrospect can be used as to use,
On the one hand it can also be compared with the power consumption of the mobile terminal for the localization method for not using the application.
It should be noted that the mobile terminal can only be in above-mentioned three kinds after real-time motion data judges under normal conditions
One kind in motion state, because each motion state is owned by more apparent kinematic parameter and distinguishes shop, it can thus be seen that this

The data of sensor acquisition determine the current kinetic motion state of the tracker, and are positioned using corresponding with each motion state 9206
Chip realizes the tracker of a lower power consumption using strategy：
When state recognition is static, due to reporting the mechanism of a state recognition result using 1s, to confirm static shape
State, can be with given threshold such as：Continuous 10 times (10s) are all determined as stationary state, and identical static identification is only all reported when 10 times
As a result just think that the tracker remains static, and asks 9206 positioning chips to be accurately positioned for the first time at this time, obtain current
Location information.Hereafter one timer can be set, it is 3 minutes such as to set interval, if motion-sensing in this 3 minutes
The real-time motion data of device, which is confirmed as remaining static always, (if breaking the stationary state of holding, restarts state
Identification process), then one-time positioning (duration, which counts, after the completion of positioning resets) is carried out every 3 minutes 9206 positioning chips of request, if
It asks in (such as 4 times) to be static several times, can will only rely on time interval later to make requests on, time interval can compare at this time
Originally 3 minutes slightly larger, such as 5 minutes；
When state recognition is to walk (one kind in active state), multiple bearing is also needed to determine that motion state judges
Correctness, ask 9206 positioning chips to be positioned for the first time immediately after, later request positioning then rely primarily on active displacement
This parameter, i.e., whenever practical active displacement and default active displacement threshold value it is in the same size when ask 9206 positioning chips to carry out
One-time positioning (displacement, which counts, after the completion of positioning resets).Active displacement then navigated to current step number by last time is multiplied by step-length and obtains
It arriving, step-length is gender input by user in the user terminal APP according to the tracker, height, weight etc. to provide basic step-length,
And be modified by table 1, it obtains closer to actual actual step size.What it is due to calculating is the displacement for leaving last time positioning, also
It needs to carry out attitude algorithm, knows about the horizontal attitude angle obtained after calculatingFollow-up distance every time can be carried out level right angle
The decomposition of coordinate system, finally obtain the O points that were positioned from last time to current point A displacement OA, specifically as shown in Figure 5；When being identified as
When running (another kind in active state), processing mode with walk identical, only threshold size is slightly different；
When state recognition is travel, still attitude algorithm algorithm will be utilized acceleration using speed as evaluation criterion
The registration of sensor is decomposed in the horizontal direction, is then integrated to obtain speed respectively, uses formula for Vi+1=Vi+at。t
For the sampling interval.Speed can be divided into 3 shelves, when in most high-grade, need to position normally opened, real-time monitoring velocity, to prevent super
Speed can then correspond to other gears of admission velocity when location finding speed is relatively low, the side of the frequency by reducing request positioning
Formula reduces power consumption and power consumption.
