It is a kind of schematic flow diagram for range calibration method that the embodiment of the present invention one provides, this implementation referring to Fig. 1, Fig. 1
The executing subject of example can be terminal, can be the equipment such as mobile phone or other intelligent terminals.Range calibration side shown in FIG. 1
Method may comprise steps of:
If S101, detecting the corresponding trigger signal of range sensor, the initial bottom for obtaining the range sensor is made an uproar value,
And value calculating is made an uproar close to threshold value and far from threshold value according to the initial bottom.
Specifically, when range sensor is triggered, terminal detects that the corresponding trigger signal of range sensor, terminal obtain
It takes the initial bottom of range sensor to make an uproar value, and is calculated according to initial bottom value of making an uproar close to threshold value and far from threshold value.
Usually there is an infrared LED lamp in the outside of range sensor, when range sensor enables, LED can be to
External emission goes out the infrared light of certain frequency, and the light-sensitive device inside range sensor can detect it is reflected infrared
Light, the infrared light value are that the initial bottom of range sensor is made an uproar value.
Terminal makes an uproar value calculating close to threshold value and far from threshold value according to the initial bottom of range sensor.It can be used to close to threshold value
It is judged whether or not object close to terminal, can be used to judge whether have object far from terminal in the ban far from threshold value.
It should be noted that distance passes when needing to use range sensor, i.e. range sensor is triggered
Sensor can enter enabled state, and initial bottom value of making an uproar is acquisition when range sensor is triggered.For example, when terminal dials electricity
When talking about or receive calls, range sensor can be triggered, and terminal obtains initial bottom and makes an uproar value at this time, and calculating is close to threshold
Value and separate threshold value.
S102, the current bottom for obtaining range sensor are made an uproar value.
Specifically, after range sensor enters enabled state, terminal is in real time or timing acquisition range sensor is worked as
Preceding bottom is made an uproar value.
The current bottom that terminal obtains range sensor by detecting current infrared light value is made an uproar value.
Further, the current bottom that terminal can obtain range sensor in real time in such a way that triggering is interrupted is made an uproar value, or
Person can also be made an uproar value at the current bottom of timing acquisition range sensor by way of poll.Concrete mode can according to actual needs into

S103, value of being made an uproar according to current bottom carry out dynamic update to close to threshold value and far from threshold value.
Specifically, terminal is made an uproar value according to the current bottom of acquisition, it is judged whether or not object proximity or far from terminal, and
Again value calibration is made an uproar close to threshold value and far from threshold value according to current bottom.
It should be noted that if just thering is object to block in range sensor when range sensor is triggered
Top causes range sensor top object reflected infrared light to be also mistakenly considered bottom and makes an uproar, at this time terminal get just
Value is made an uproar at beginning bottom will be abnormal higher, thus be calculated close to threshold value and also can be higher far from threshold value, and close to threshold value and remote
It is to determine whether judgment basis that object is close and separate with making a return journey from threshold value, then sentences extremely when close to threshold value and far from threshold value
The inevitable inaccuracy of disconnected result, thus cannot effectively object close to when close the peripheral hardwares such as display screen and reach power saving and false-touch prevention
Effect.Therefore in order to solve this problem, range sensor it is enabled after, terminal in real time or timing acquisition Distance-sensing
The current bottom of device is made an uproar value, and is recalculated according to current bottom value of making an uproar close to threshold value and far from threshold value, is made close to threshold value and far from threshold
The state for the exact value that value calibration is blocked to no object, so that accurate detection object is close and separate.
From the exemplary range calibration method of above-mentioned Fig. 1 it is found that in the present embodiment, the corresponding touching of range sensor is being detected
When signalling, the initial bottom for obtaining range sensor is made an uproar value, is calculated according to initial bottom value of making an uproar close to threshold value and far from after threshold value,
The current bottom for obtaining range sensor is made an uproar value, and makes an uproar value to close to threshold value and separate threshold value progress dynamic update according to current bottom.
By this dynamic calibration mode, make the state that exact value is calibrated to close to threshold value and far from threshold value, thus accurate detectable substance
Body it is close and separate so that the perceived distance of range sensor is accurately calibrated, to improve the operating body of user
It tests and intelligent level.
Embodiment two:
Referring to fig. 2, Fig. 2 is a kind of schematic flow diagram of range calibration method provided by Embodiment 2 of the present invention, this implementation
The executing subject of example can be terminal, can be the equipment such as mobile phone or other intelligent terminals.Range calibration side shown in Fig. 2
Method may comprise steps of:
If S201, detecting the corresponding trigger signal of range sensor, the bottom of the range sensor preset quantity is obtained
It makes an uproar value.
Specifically, when range sensor is triggered, terminal detects that the corresponding trigger signal of range sensor, terminal obtain
The initial bottom of range sensor preset quantity is taken to make an uproar value.
Wherein, preset quantity can be 10, that is, obtains 10 bottoms and make an uproar value, but it is not limited to this, and specific preset quantity can
To be configured according to the actual situation, herein with no restrictions.
S202, the bottom for calculating preset quantity make an uproar the average value of value, set initial bottom for the average value and make an uproar value.
Specifically, the bottom for calculating preset quantity is made an uproar the average value of value, and initial bottom when being triggered as range sensor is made an uproar
Value.
The sum of S203, value that initial bottom is made an uproar and preset separate threshold shift are disposed remotely from threshold value.
Specifically, initial bottom make an uproar be worth preset separate threshold shift and for far from threshold value.
S204, value that initial bottom is made an uproar and the preset sum close to threshold shift are disposed proximate to threshold value.
Specifically, initial bottom make an uproar be worth it is preset close to threshold shift and for close to threshold value.
Wherein, preset separate threshold shift can be set to 100, preset to can be set to close to threshold shift
150, but it is not limited to this, specific according to the actual situation to be set far from threshold shift and close to threshold shift
It sets, herein with no restrictions.The standard shielded and more than 5cm Shi Liangping of going out when being usually lower than 2cm according to object and terminal distance carries out
Setting.
S205, the current bottom for obtaining range sensor are made an uproar value.
Specifically, after range sensor enters enabled state, the terminal infrared light value current by detection, in real time or
The current bottom of timing acquisition range sensor is made an uproar value, and judge current bottom make an uproar value whether be less than it is current far from threshold value, and judgement
Whether bottom value of making an uproar is greater than close to threshold value.
Further, the current bottom that terminal can obtain range sensor in real time in such a way that triggering is interrupted is made an uproar value, or
Person can also be made an uproar value at the current bottom of timing acquisition range sensor by way of poll.Concrete mode can according to actual needs into
Row selection, herein with no restrictions.
Terminal executes step S206 when confirming that value is made an uproar less than far from threshold value in current bottom；Confirming that current bottom value of making an uproar is greater than
When close to threshold value, step S207 is executed.
If S206, current bottom make an uproar, value is less than separate the threshold value, will be far from threshold value be updated to current bottom make an uproar value with preset
Droop value difference, and by close to threshold value be updated to current bottom make an uproar value and it is preset close to threshold shift and.
Specifically, if current bottom is made an uproar, value is less than far from threshold value, illustrates have object far from range sensor, terminal at this time
Using current bottom make an uproar value and preset droop value difference as updated separate threshold value, current bottom value of making an uproar is connect with preset
The sum of nearly threshold shift as updated close to threshold value so that updated separate threshold value and reducing close to threshold value.
Wherein, droop value is a constant, usually can be set to 50, and but it is not limited to this, specific fixed inclined
Difference can be configured according to the actual situation, herein with no restrictions.
It should be noted that being under normal conditions the positive number greater than zero close to threshold value and far from threshold value, if current bottom
The difference of value of making an uproar and preset droop value then can be updated directly to zero far from threshold value less than zero.
Further, if current bottom is made an uproar, value is less than far from threshold value, can be by way of triggering far from interrupting
Reason.When terminal is detected far from interruption, then it is updated according to current bottom value of making an uproar to separate threshold value and close to threshold value.
It is understood that in embodiments of the present invention, when value is made an uproar less than far from threshold value in current bottom, updating far from threshold value
With close to threshold value, in other embodiments, or value is made an uproar when being less than or equal to far from threshold value in current bottom, updates separate threshold
Value and close to threshold value.
Optionally, it if the method can also include: that value is made an uproar less than the separate threshold value in the current bottom, reports separate
Event.
Specifically, terminal, which is reported, is handled far from event to application layer, if application layer is worked as according to far from event judgement
The devices such as preceding display screen are closed, and the operation such as can execute and enable the devices such as display screen again, and wake up system.
If S207, current bottom make an uproar, value greater than described close to threshold value, make an uproar value, and will be remote by the smallest base for obtaining range sensor
From threshold value be updated to smallest base make an uproar value and preset separate threshold shift and, range sensor will be updated to close to threshold value
Maximum range.
Specifically, if current bottom is made an uproar, value is greater than close to threshold value, illustrates there is object proximity range sensor, terminal at this time
The smallest base for obtaining range sensor is made an uproar value, using smallest base make an uproar value and preset separate threshold shift sum as updated
Far from threshold value, and using the maximum range of range sensor as updated close to threshold value.Wherein, smallest base value of making an uproar refers to distance
The sensor bottom that terminal has currently been got under enabled state is made an uproar the minimum value in value, and the maximum range of range sensor is
Refer to the infrared light value of maximum that range sensor can receive, such as maximum range is 1024, i.e., it is maximum to can receive back red
Outer light value is 1024.
Further, if current bottom is made an uproar, value is greater than close to threshold value, can be triggering close to by way of interrupting
Reason.When terminal is detected close to interruption, then it is updated according to current bottom value of making an uproar to far from threshold value and close to threshold value.
It is understood that in embodiments of the present invention, current bottom make an uproar value be greater than close to threshold value when, update far from threshold value
With close to threshold value, in other embodiments, or value is made an uproar when being more than or equal to close to threshold value in current bottom, updates separate threshold
Value and close to threshold value.
Optionally, if the method can also include: the current bottom make an uproar value be greater than it is described close to threshold value, report close
Event.
Specifically, terminal is reported close to event and is handled to application layer, and application layer can be carried out according to this close to event
The devices such as current display screen are closed, and sleeping system etc. operates.
In order to better understand the present embodiment, now it is described as follows by a specific application example.
Assuming that bottom of the mobile phone terminal when no any object is blocked is made an uproar, value is 300, it is assumed that separate threshold values offset is 100,
Close to threshold values offset be 150, then under no any object circumstance of occlusion it is available close to threshold value be 300+150=450, far
It is 300+100=400 from threshold value.
When mobile phone terminal is when an incoming call sound phone, just there is object to block above range sensor, this
When according to the initial bottom of step S201 to the calculated range sensor of step S202 make an uproar value be 700, it is assumed that far from threshold values deviate
Amount is 100, is 150 close to threshold values offset, then calculated close to threshold value 700+150=according to step S203 to step S204
850, it is 700+100=800 far from threshold value.If using at this time close to threshold value and far from threshold value as judging whether there is object
Close and separate foundation, then it is understood that object closely can just must be considered having object close by mobile phone terminal.But
If blocking the object above range sensor during mobile phone connects phone and being removed, then obtained according to step S205
The current bottom taken value of making an uproar becomes smaller, and if judge that current bottom value of making an uproar is less than far from threshold value according to step S206, to separate threshold value
It is updated with close to threshold value, specifically, if current bottom is made an uproar, value is 500, according to the updated separate threshold value of step S206
For 500-50=450, updated close to threshold value is 500+150=650, is continued when blocking the object above range sensor
Far from when, it is assumed that for object infinitely far from when blocking without any object, current bottom value of making an uproar is restored to 300, then basis at this time
The updated separate threshold values that step S206 is obtained be 300-50=250, it is updated close to threshold values be 300+150=450；And
When there is object proximity, obtaining current the smallest bottom value of making an uproar according to step S207 is 300, then updated close to threshold value is maximum
Range 1024, updated separate threshold value are 300+100=400.As can be seen that at this time close to threshold values and far from threshold values
It is calibrated to threshold range when no any object is blocked.
From the exemplary range calibration method of above-mentioned Fig. 2 it is found that in the present embodiment, firstly, detecting range sensor pair
When the trigger signal answered, the bottom for obtaining range sensor preset quantity is made an uproar value, and the bottom of calculated preset quantity is made an uproar value
Average value is made an uproar value as initial bottom, and acquisition that can be relatively accurate by the way of average value is calculated after this multiple specimen samples
Initial bottom is made an uproar value, and the interference of individual exceptional samples is avoided；Then, value calculating is made an uproar close to threshold value and far from threshold value according to initial bottom
Afterwards, terminal is in real time or the current bottom of timing acquisition range sensor is made an uproar value, if current bottom is made an uproar, value, will be remote less than separate threshold value
Current bottom is updated to from threshold value to make an uproar the difference of value and preset droop value, and will be updated to current bottom close to threshold value and be made an uproar value and pre-
If the sum close to threshold shift, if current bottom is made an uproar, value is made an uproar value greater than the smallest base for close to threshold value, obtaining range sensor,
And will be far from threshold value be updated to smallest base make an uproar value and preset separate threshold shift and, will be updated to close to threshold value apart from biography
The maximum range of sensor.By this dynamic calibration mode, make the state that exact value is calibrated to close to threshold value and far from threshold value,
So that accurate detection object is close and separate, so that the perceived distance of range sensor is accurately calibrated, to improve
The operating experience and intelligent level of user；Finally, passing through on the basis of close to threshold value and separate threshold value by accurate alignment
It reports close to event and far from event, enables application layer current according to closing is accurately executed close to event and far from event
The devices such as display screen and sleeping system, and the operation such as the devices such as display screen are enabled again and wake up system, it further improves
Intelligent level and the operating experience for promoting user.
