In view of the above-mentioned problems, the embodiment of the present application proposes a kind of calibration method, the embodiment of the present application is carried out below detailed
It introduces.
Referring to Fig. 1, Fig. 1 is that the embodiment of the present application provides a kind of structural schematic diagram of calibration system 1000, including moves
Dynamic terminal 1100 and calibration jig 1200, the mobile terminal include sliding module 1300 and position sensor 1400, the shifting
Dynamic terminal 1100 controls the sliding of the sliding module 1300 by the position sensor 1400；
The calibration jig 1200, for determining the traveled distance of the sliding module；And for according to first distance
Determining the calibration value of the deceleration point of the sliding module, the deceleration point includes the first deceleration point or the second deceleration point, and described the
One deceleration point is the deceleration point for once effectively skidding off process, and second deceleration point is the primary deceleration point for effectively sliding into process；
The mobile terminal 1100 controls plan for generating PWM moderating process according to the PWM control parameter calibration value
Slightly；
The mobile terminal 1100, after being also used to control the sliding module arrival deceleration point, according to the PWM
Deceleration control strategy controls the sliding module deceleration slip second distance, the difference between the second distance and first distance
Less than pre-determined distance, the first distance is that the deceleration point arrives the distance between maximum travel position, the range position
It is set to the associated maximum travel position of the deceleration point.
Wherein, any following a kind of device: camera mould group, iris sensor, structure has can be set in the slider module
Optical sensor etc. does not do unique restriction herein.
Wherein, the sliding module is corresponding with the first deceleration point during skidding off, and is corresponding with second during slide-in
Deceleration point, first deceleration and second deceleration point can be identical position, be also possible to different position.
Wherein, after mobile terminal control sliding module reaches deceleration point, sliding is controlled according to PWM deceleration control strategy
Mould group deceleration slip second distance simultaneously stops sliding, and second distance is less than between first distance and second distance and first distance
Difference be less than pre-determined distance, first distance be deceleration point arrive the distance between maximum travel position, range is deceleration point
Associated range.
Wherein, referring to FIG. 2, the distance between L01 to L11 is equal to sliding rail length, sliding rail bottom is located at L01, maximum
Travel position is located at L11, and mobile terminal controls sliding module during skidding off, and slides from L01 to the direction L11, first subtracts
Speed point is located at 1203 positions, and sliding module is slided during slide-in from L11 to the direction L01, and the second deceleration point is located at 1204
At position.L12 is practical stop place of sliding module during skidding off, and L02 is reality of sliding module during slide-in
Border stop place.
For example, the range of sliding module be the practical overall length Lmm of sliding rail, first distance 0.2mm, second away from
From for 0.16mm.During skidding off, the first deceleration point 1203 is at the position with sliding rail bottom L01 distance (L-0.2) mm, i.e.,
With L11 distance 0.2mm at maximum travel position, 1203 position in Fig. 2 can determine the first deceleration point by calibration jig
1203.After sliding module reaches the first deceleration point 1203, sliding module is made to continue forward slip by PWM control strategy
0.16mm is at the position L12 and stops, and sliding module does not reach maximum travel position L11 at this time, and second distance and first away from
Difference between is 0.04mm.Further, since the actual progress of calibration jig is 0.02mm, because the first deceleration point 1203 can
It can occur in distance L11 there are also the distance range of 0.18mm-0.22mm, the difference between the second distance and first distance exists
Between 0.02-0.06mm.
Meanwhile during slide-in, the second deceleration point 1204 passes through at the position with sliding rail bottom L01 distance 0.2mm
Calibration jig can determine the second deceleration point 1204.After sliding module reaches the second deceleration point 1204, pass through PWM control strategy
So that sliding module continues forward slip 0.16mm and at the position L02 and stops, sliding module is not up to sliding rail bottom at this time
L01, so there is no the noises of stall, therefore do not have noise generation, meanwhile, the gap of a 0.02-0.06mm is left,
This gap also in the range of designing allows, realizes the consistency in gap in place and noise balance.
Wherein, mobile terminal further includes application processor, and application processor is entirely moved using various interfaces and connection
The various pieces of dynamic terminal, by running or executing the software program and/or module that are stored in memory, and calling storage
Data in memory execute the various functions and processing data of mobile terminal, to carry out integral monitoring to mobile terminal.
Wherein, the main processing operation system of application processor, user interface and application program etc..
As can be seen that the calibration system provided in the embodiment of the present application, including mobile terminal and calibration jig, the movement
Terminal includes sliding module and position sensor, and the mobile terminal is by the position sensor with impulse modulation width PWM
Mode controls the sliding of the sliding module；And the calibration jig, for determining the traveled distance of the sliding module；
And the calibration value of the deceleration point for determining the sliding module according to first distance, the deceleration point include the first deceleration point
Or second deceleration point, first deceleration point are the deceleration point for once effectively skidding off process, second deceleration point is once to have
Imitate the deceleration point of slide-in process；And the mobile terminal, slow down for generating PWM according to the PWM control parameter calibration value
Control strategy；And after the control sliding module reaches the deceleration point, according to the PWM deceleration control strategy control
The sliding module deceleration slip second distance is made, the difference between the second distance and first distance is less than pre-determined distance,
The first distance is that the deceleration point arrives the distance between maximum travel position, and the maximum travel position is the deceleration point
Associated maximum travel position.As it can be seen that calibration system can determine the traveled distance of sliding module by calibration jig, and really
Determine the position of the deceleration point of mobile terminal sliding module, and after combination PWM control sliding module sliding second distance and stop, protects
Card mobile terminal sliding module skids off process every time and slides into process and all stops in fixed position, since second distance is less than first
Distance, there are gaps to avoid bad student's noise between sliding module and sliding rail bottom during sliding into, it is ensured that sliding process
In in place with the consistency of noise, be conducive to mobile terminal control sliding module accuracy and stability.
In a possible example, the mobile terminal is also used to control by the position sensor with PWM mode
The sliding module is at the uniform velocity slided with First Speed；And after sliding module sliding third distance, according to default speed change
Strategy makes the sliding module slide into the deceleration point, at this point, the sliding module has second speed, second speed
Degree is less than the First Speed.
Wherein, when sliding into or out sliding module, sliding module is controlled with PWM mode with the by position sensor
One speed is at the uniform velocity slided, and is the first sliding phase of sliding module, after sliding module at the uniform velocity slides third distance, according to pre-
If the sliding module that makes of shift strategy slide into deceleration point, be the second sliding phase of sliding module, it is sliding for reaching deceleration point
Dynamic model group has second speed, wherein second speed is less than First Speed.
For example, after sliding module at the uniform velocity slides 0.5mm with the speed of 1000pps, entering in the first sliding phase
Second sliding phase, sliding module speed-raising at this time is to 2500pps and quick deceleration is to 800pps, and just reaches deceleration point
When, speed 800pps.The prior art is that speed is switched to 200pps by 2500pps, is changed to 200pps in the application
800pps will not be stopped in advance because the speed of 800pps completes remaining distance enough under the action of Hall parking mechanism
Under.
Wherein, third sliding phase is entered after the completion of the second sliding phase, that is, accelerates sliding second after reaching acceleration point
Distance is simultaneously stopped.Accurate control of the number realization of PWM wave to eventually forming is set by software application, and sliding module is made to exist
Final stage closes motor drive signal after can accurately running 0.16mm, if can then leave 0.02- during slide-in
The noise of stall is not present since motor does not run to sliding rail bottom in the gap of 0.06mm.
As can be seen that in the embodiment of the present application, by way of accurately controlling calibration jig and pwm motor, so that
Sliding module can be realized in each sliding process in the generation for the noise that same position precisely stops sliding and avoids
The consistency in gap and noise balance in place.
In a possible example, the mobile terminal is also used to according to described in PWM deceleration control strategy control
Sliding module closes motor drive signal so that the sliding module stops after the deceleration point deceleration slip first distance
Sliding；The calibration jig is also used to record the end position when sliding module stops sliding.
As can be seen that after the sliding module accelerates sliding first distance, closing motor driving in the embodiment of the present application
Signal avoids sliding module from sliding further along, meanwhile, truing tool is also used to record stop bits when sliding module stops sliding
It sets, it is thus possible to determine the traveled distance of sliding module according to end position.
In a possible example, the PWM moderating process control strategy is for controlling the sliding module by described
Second speed deceleration slip second distance, and the second speed is gradually decreased as zero in sliding process.
For example, speed is 800pps after sliding module reaches deceleration point, and during sliding second distance, speed
It gradually decreases, when just sliding second distance, speed is reduced to zero, simultaneously closes off motor drive signal at this time, slides
The change of mould group will not be slided further along.
As can be seen that PWM moderating process control strategy can control the sliding module by described in the embodiment of the present application
Second speed deceleration slip second distance, and the second speed is gradually decreased as zero in sliding process, so that sliding die
Group can stop before reaching maximum travel position.
In a possible example, the calibration jig, the mobile terminal, be also used to according to described default second away from
From determining PWM control parameter；And PWM moderating process control strategy is generated according to the PWM control parameter.
Wherein, second distance is a fixed distance, can determine PWM control parameter, PWM control ginseng according to second distance
Number is PWM waveform number, i.e., by a certain number of PWM waveform numbers of output, sliding module can be made accurately to slide second
Distance length, such as when PWM control parameter is 500, that is, exporting 500 waveforms can make sliding module accurately run 0.16mm,
To stop before reaching maximum travel position.
As can be seen that the accurate control to retarding travel may be implemented by setting PWM control parameter in the embodiment of the present application
System exists so that after can accurately running second distance after sliding module arrival deceleration point and stopping sliding to realize every time
Same position stops sliding.
In a possible example, in terms of the traveled distance of the determination sliding module, the calibration jig
It is specifically used for: the sliding module is determined according to the numerical value of the sliding module initial position and the numerical value for stopping sliding position
Traveled distance, the reality are less than or equal to the range from long.
As can be seen that in the embodiment of the present application, according to the number of the numerical value of sliding module initial position and stopping sliding position
Value, determines the traveled distance of Hu Aodongmo group, simultaneously, it is to be ensured that practical row is less than or equal to range.
In a possible example, the sliding module includes the top side of the mobile terminal；The sliding die
The sliding process of group includes skidding off process and sliding into process, and during described skid off, the top side of the mobile terminal is outlying
From the mobile terminal, during described slide into, the top side of the mobile terminal is close to the mobile terminal.
As can be seen that sliding module further includes the top side of mobile terminal, in sliding module in the embodiment of the present application
During skidding off, top side is outlying from mobile terminal, it is only necessary to guarantee that the traveled distance of sliding module is less than range, in cunning
During the slide-in of dynamic model group, top side is close to mobile terminal, it is only necessary to guarantee between sliding module and sliding rail bottom there are
Gap.
In a possible example, the calibration jig is also used to detecting the traveled distance in default row
When journey range, determine that the Standard of the sliding module is accurate.
Wherein, it in the practical whole process L=L12-L02 according to sliding module, and is compared with preset strokes range, in range
It then continues to run, does not stop then calibrating in preset strokes range, search Standard problem.
As can be seen that can judge Standard problem according to traveled distance in the embodiment of the present application, can find in time
Standard problem.
In a possible example, the position sensor is multiple position sensings for controlling the sliding module
At least one position sensor in device；The process or the slide-in process of skidding off includes three-step gear shift process.
As can be seen that skidding off process or sliding into process for sliding module all includes three-step gear shift mistake in the embodiment of the present application
Journey can be realized and quickly skid off or slide into, and speed is avoided to cause very much to rebound after skidding off or sliding into shock and to mobile whole fastly
End and sliding module damage.

The position limiting structure of the top side at end, first deceleration point and second deceleration point are used for the mobile terminal for the cunning
The sliding speed of dynamic model group is reduced speed now by the second speed.
Wherein, pallet is for placing and clamping mobile terminal to be calibrated.Firstly, mobile terminal is put into calibration jig support
