Embodiment one
Fig. 1 is a kind of flow diagram of the control method for infrared proximity transducer that the embodiment of the present invention one provides, should
Method can be executed by the control device of infrared proximity transducer, and wherein the device can be implemented by software and/or hardware, and generally may be used
It integrates in the terminal.As shown in Figure 1, this method comprises:
Step 101 is used to determine that close/current decision gate limit value far from state to be non-strong in infrared proximity transducer
In the state of optical mode threshold value, current environment light intensity value is obtained in real time.
Illustratively, the concretely mobile phone, smartwatch, tablet computer, game machine, a of the mobile terminal in the present embodiment
Personal digital assistant and digital multimedia player etc. are configured with the various equipment of infrared proximity transducer.
Illustratively, infrared proximity transducer can convert the infra-red intensity measured to and its proportional
The measured value can be known as proximity values by measured value.In general, proximity values can be the analog-digital converter in infrared proximity transducer
The output valve of (Analog-to-Digital Converter, ADC), abbreviation ADC value or AD value.
In order to allow infrared proximity transducer detection object close to or away from, can generally preset for determine close to/
Decision gate limit value far from state.Decision gate limit value may include that may also comprise close to threshold value close to threshold value and far from thresholding
Value.
Illustratively, if it is determined that threshold value only includes close to threshold value, when the current proximity values of infrared proximity transducer are big
When close to threshold value, it can determine that as proximity state；When the current proximity values of infrared proximity transducer are less than close to threshold value,
It can determine that as far from state.
Illustratively, if it is determined that threshold value includes close to threshold value and far from threshold value, when working as infrared proximity transducer
When preceding proximity values are greater than close to threshold value, it can determine that as proximity state；When the current proximity values of infrared proximity transducer are less than far
When from threshold value, it can determine that as far from state；When the current proximity values of infrared proximity transducer are in far from threshold value and are approached
When between threshold value, keep state when last judgement constant.
In general, influenced by factors such as environment, in the case where the use state of user is basically unchanged, infrared proximity sensing
The proximity values of device may also can be fluctuated in a small range, in order to avoid occurring frequently to cut between proximity state and separate state
It changes, preferably decision gate limit value had not only included close to threshold value, but also including far from threshold value.
The infrared light for including in environment can have some impact on the proximity values of infrared proximity transducer, especially sunlight
Under sufficient environment, infra-red intensity is very high, is easy to cause infrared proximity transducer device working condition abnormal, proximity values may
It can frequently jump, such as jump to a very big value from a smaller value in a short time, then jump back lesser
Value, and then lead to the erroneous judgement to the proximity state of external object, the normal use of user is influenced, screen such as occurs and is frequently extinguishing
And the phenomenon that switching between lighting.Assuming that during conversing under the sunlight of user outdoors, it is desirable to carry out on the screen
Other operations, such as input extension number, check address list or consult a map other information when, screen can separate user's head, if
Infrared proximity transducer is influenced by the infrared ray in sunlight and makes proximity values that frequent jump occur, then screen will frequency
It is numerous to extinguish and switching between lighting, seriously affect the normal operating of user on the screen.
In order to avoid the generation of the above problem, in the present embodiment, by infrared proximity transducer be used to determine close to/it is separate
The decision gate limit value of state is divided into two types, i.e., strong optical mode threshold value and non-strong optical mode threshold value, wherein strong optical mode
In threshold value close to threshold value be greater than in non-strong optical mode threshold value close to threshold value.Use strong optical mode threshold value for
When for determining the current decision gate limit value of close/separate state, improved on the basis of non-strong optical mode threshold value close
Threshold value makes in the case where there is extraneous infrared ray interference, and the proximity values of infrared proximity transducer are not readily reachable by close to thresholding
Value can be reduced close to/the erroneous judgement far from state.
Preferably, working condition of the infrared proximity transducer in the case where there is extraneous infrared ray interference can be adjusted
It grinds, for example, the infrared proximity transducer of statistics available setting quantity is not in the case where being blocked and there is extraneous infrared ray interference
The highest proximity values that can reach, the highest proximity values will be set above close to threshold value in strong optical mode threshold value,
When ensuring that the proximity values of infrared proximity transducer jump under strong light, will not due to proximity values are more than close to threshold value by
It is mistaken for proximity state.It is understood that should be less than infrared proximity transducer close to threshold value in strong optical mode threshold value
Proximity values range ability maximum boundary value.
In this step, in infrared proximity transducer for determining that close/current decision gate limit value far from state is non-
In the state of strong optical mode threshold value, current environment can be obtained in real time by integrated ambient light sensor in the terminal
Light intensity value determines whether current decision gate limit value being adjusted to strong optical mode door according to current environment light intensity value so as to subsequent
Limit value.
If step 102, acquired current environment light intensity value, which are greater than, presets strong optic terminus value, by current decision threshold
Value is adjusted to strong optical mode threshold value.
Illustratively, mobile terminal factory before, can to setting quantity mobile terminal infrared proximity transducer into
Row investigation presets strong optic terminus value according to finding determination.For example, the infrared proximity of statistics available different mobile device senses
In the state of not blocking, when what value is environmental light intensity value reach, measured obtained proximity values can jump device respectively, general
The smallest environmental light intensity value is determined as presetting strong optic terminus value.
It is understood that the infra-red intensity value direct proportionality in environmental light intensity angle value and environment, can be used ring
Border light intensity value measures the infra-red intensity in environment.In this step, judging that current environment light intensity value is big
When presetting strong optic terminus value, current decision gate limit value is adjusted to strong optical mode threshold value, it is infrared in environment light to reduce
Influence of the line to infrared proximity transducer measurement result.
Step 103, control infrared proximity transducer are carried out based on strong optical mode threshold value close to the/judgement far from state.
In this step, control infrared proximity transducer is carried out based on strong optical mode threshold value close to the/judgement far from state,
Make in the case where there is extraneous infrared ray interference, the proximity values of infrared proximity transducer are not readily reachable by close to threshold value, can be subtracted
Few close/erroneous judgement far from state.
It is determining close to or away from after state, can control mobile terminal execution corresponding operation.For example, in communication process
In, extinguish screen under proximity state, lights screen under separate state.
The control method for the infrared proximity transducer that the embodiment of the present invention one provides, infrared proximity transducer is used to sentence
Fixed close/decision gate limit value far from state is divided into two types, i.e., strong optical mode threshold value and non-strong optical mode threshold value, by force
In optical mode threshold value close to threshold value be greater than non-strong optical mode threshold value in close to threshold value, in current environment luminous intensity
Non- strong optical mode threshold value is adjusted to strong optical mode threshold value, and control infrared proximity greater than when presetting strong optic terminus value by value
Sensor is carried out based on strong optical mode threshold value close to the/judgement far from state.By using above-mentioned technical proposal, in environment light
When intensity is larger, proximity state is determined close to threshold value using biggish, influence of the strong light to result is determined can be weakened,
It prevents from judging by accident when close/separate state to external object determines, screen is avoided frequently to extinguish and lighting it
Between switch phenomena such as appearance.
On the basis of the above embodiments, control infrared proximity transducer be based on strong optical mode threshold value carry out close to/
After judgement far from state, it may also include that and obtain current first environment light intensity value, if first environment light intensity value is less than
Non- strong optic terminus value is preset, then current decision gate limit value is adjusted to non-strong optical mode threshold value, and controls infrared proximity sensing
Device is carried out based on non-strong optical mode threshold value close to the/judgement far from state.Illustratively, when environmental light intensity angle value is lower than certain
Numerical value when, the infrared ray in environment influences the proximity values of infrared proximity transducer smaller, can restore at this time to non-strong light to sentence
Mould-fixed, to guarantee measurement sensitivity of the infrared proximity transducer in normal environment.
On the basis of the above embodiments, the separate threshold value in strong optical mode threshold value can be greater than non-strong optical mode thresholding
Separate threshold value in value.Under strong light determinating mode, if based on this is determined close to threshold value in strong optical mode threshold value
When be proximity state, can illustrate that infrared proximity transducer is blocked, after shelter is removed, if in strong optical mode threshold value
It is smaller far from threshold value, it would be possible that can not normally determine far from state, so, it can be remote in non-strong optical mode threshold value
From the numerical value far from threshold value is improved on the basis of threshold value, the separate threshold value in strong optical mode threshold value is obtained, is guaranteed strong
Separate state under light determinating mode can be identified normally.Illustratively, the proximity values range ability of infrared proximity transducer
Maximum boundary value be 1023.In non-strong optical mode threshold value is 400 close to threshold value, is 300 far from threshold value；Strong optical mode
In formula threshold value is 900 close to threshold value, is 850 far from threshold value.Infrared proximity transducer chip is interfered by strong light
Afterwards, the beating scope of proximity values does not all exceed strong optical mode door generally 700 hereinafter, so regardless of proximity values jump
In limit value close to threshold value, while can also guarantee that the separate state under strong light determinating mode can be identified normally.
Embodiment two
Fig. 2 is a kind of flow diagram of the control method of infrared proximity transducer provided by Embodiment 2 of the present invention, this
Embodiment is optimized based on above-described embodiment, in the present embodiment, further comprises the steps of: the use in infrared proximity transducer
In the state of determining that close/current decision gate limit value far from state is non-strong optical mode threshold value, control infrared proximity is passed
Sensor is carried out based on the non-strong optical mode threshold value close to the/judgement far from state；According to based on non-strong optical mode threshold value
Close to/far from state determination results adjustment preset strong optic terminus value.
Correspondingly, the method for the present embodiment includes the following steps:
Step 201 is used to determine that close/current decision gate limit value far from state to be non-strong in infrared proximity transducer
In the state of optical mode threshold value, control infrared proximity transducer is based on non-strong optical mode threshold value and carries out close/separate state
Judgement, and in real time obtain current environment light intensity value.
Whether the acquired current environment light intensity value of step 202, judgement, which is greater than, is preset strong optic terminus value, if so, holding
Row step 203；Otherwise, step 205 is executed.
Current decision gate limit value is adjusted to strong optical mode threshold value by step 203.
Step 204, control infrared proximity transducer are carried out based on strong optical mode threshold value close to the/judgement far from state.
Step 205 adjusts default Qiang Guang circle according to close/separate state determination results based on non-strong optical mode threshold value
Limit value returns to step 202.
Illustratively, different infrared proximity sensor components are different for the perception of environment light infra-red intensity,
Some infrared proximity transducer chips proximity values when environmental light intensity angle value is greater than (lux) 5000lux will beat；And have
Infrared proximity transducer chip environmental light intensity angle value be greater than 8000lux when, proximity values can be just mutated.That is, passing through
One unified default strong optic terminus value is come to judge whether an infrared proximity transducer has currently been subjected to the interference of strong light be to deposit
In problem.In addition, using the cumulative time progressively longer with device, certain variation may also can occur for device performance.

It changes.
Optionally, this step can include: if being detected in preset duration based on non-strong optical mode threshold value close/remote
Number from altering event reaches preset times threshold value, then it is default to judge whether the current environment light intensity value obtained at this time is less than

Wherein, close/separate altering event, which is specifically included from far from state, becomes proximity state, further includes from proximity state
Become far from state.When influence of the infrared ray in environment to infrared proximity transducer is bigger, proximity values will be sent out
Raw jump, after an integration period (such as 100ms) is completed, proximity values that obtained proximity values and a upper integration period obtain
It is widely different, will generally occur once close to/far from altering event.User is close/separate in usual use process
Movement can not have so fast, can judge accordingly whether infrared proximity transducer is abnormal, and then judge whether
It needs to be adjusted to presetting strong optic terminus value.Illustratively, in preset duration (in such as 2 seconds), what is detected is close/separate
The number of altering event reaches preset times threshold value (such as 4 times), and user is normally close to separate movement in the preset duration
Can not complete it is so multiple, so can illustrate that infrared proximity transducer is abnormal.Under recordable at this time work as front ring
Border light intensity value, such as 6500lux, if the current environment light intensity value be greater than preset strong optic terminus value (such as
5000lux), then in later judgement, strong optic terminus value is still preset using this；If the current environment light intensity value is small
In presetting strong optic terminus value (such as 8000lux), then just using current environment light intensity value as new default strong optic terminus
Value.
Preferably, if based on non-strong optical mode threshold value detected in preset duration close to/far from altering event
Number reaches preset times threshold value, then judges whether the current environment light intensity value obtained at this time is less than and preset strong optic terminus value,
If can include: reached based on close/number far from altering event that non-strong optical mode threshold value detects in preset duration
Preset times threshold value, and the time interval between every two adjacent close/separate altering event is less than preset interval threshold value, then
Judge whether the current environment light intensity value obtained at this time is less than and presets strong optic terminus value.The advantages of this arrangement are as follows can be more
Add and accurately judges whether infrared proximity transducer is abnormal.
Illustratively, if according to based on the close/determining default strong far from state determination results of non-strong optical mode threshold value
Optic terminus value does not need to adjust, then can directly return to step 202.
The embodiment of the present invention on that basi of the above embodiments, increases the related step that strong optic terminus value is preset in dynamic adjustment
Suddenly, the default strong optic terminus value for being suitble to current infrared proximity transducer can be determined more accurately, to be determined more accurately
