Embodiment one
Fig. 1 is a kind of flow diagram of the control method for proximity sensor that the embodiment of the present invention one provides, this method
It can be executed by the control device of proximity sensor, wherein the device can be implemented by software and/or hardware, and can generally be integrated in shifting
In dynamic terminal.As shown in Figure 1, this method comprises:
Step 101, the current proximity values for obtaining proximity sensor.
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 proximity sensor.
Proximity sensor in the present embodiment can be the proximity sensor of any one type, as long as can recognize that outer
Boundary's object close to or away from movement, for example, it may be infrared proximity transducer or ultrasonic type proximity sensor etc.
Deng.Proximity sensor generally measures object with the variation of the distance between measured external object and proximity sensor value
Close to or away from the measured value of proximity sensor is referred to alternatively as proximity values, and proximity values can be used for indicating proximity sensor and object
The size of the distance between body.Relationship between proximity values and distance value can be directly proportional or inversely proportional, tool
Body can be determined according to the working principle of proximity sensor.Threshold register in proximity sensor can be stored for determining to connect
Closely/decision threshold far from state, the decision threshold generally comprise upper limit threshold and lower threshold, when proximity values are by being less than the upper limit
Threshold value becomes greater than upper limit threshold, or from when becoming smaller than lower threshold greater than lower threshold, proximity sensor can be generated and be connect
Closely/interrupted far from Status Change, illustrate that close/separate state is changed.It is close/to interrupt far from Status Change including two kinds
Change is interrupted, i.e., is interrupted from the change for becoming proximity state far from state and become in the change far from state from proximity state
It is disconnected.
By taking infrared proximity transducer as an example, infrared proximity transducer is built-in with infrared transmitting tube and infrared receiving tube, infrared
Transmitting tube launches outward infrared ray, detects infra-red intensity received by infrared receiving tube to measure the distance of object distance,
Infrared proximity transducer can convert the infra-red intensity measured to the measured value with its proportional, can be by the measurement
Value is known as proximity values.In general, proximity values can be the analog-digital converter (Analog-to-Digital in infrared proximity transducer
Converter, ADC) output valve, abbreviation ADC value or AD value.It is understood that proximity values are bigger, illustrate external object away from
It is closer from infrared proximity transducer, it is possible to think that the proximity values of infrared proximity transducer and distance value are inversely proportional relationships
's.For infrared proximity transducer, the upper limit threshold of decision threshold is close to threshold value, and lower threshold is far from threshold value.When
When proximity values are greater than close to threshold value, it can determine that as proximity state；When proximity values are less than far from threshold value, can determine that as far from shape
State；When proximity values are in far from threshold value and close between threshold value, keep state when last judgement constant.
The specific opportunity of current proximity values for obtaining proximity sensor is not construed as limiting in this step, it illustratively, can be
When detecting proximity sensor starting, the current proximity values of proximity sensor are obtained；Connecing for proximity sensor can also received
Closely/far from Status Change interrupt after, obtain the current proximity values of proximity sensor；It can also be in the specified operation for detecting user
When, obtain the current proximity values of proximity sensor.
Step 102 sets proximity values constant interval according to current proximity values, and two boundary values of constant interval are made respectively

Example value is equal to the difference of 1 with the second ratio value with 1 difference, that is, the first ratio value of note is a, and the second ratio value of note is b, then a-1=
1-b=c.The value of c can freely be set, such as can utmostly be determined according to the current proximity values of permission are changed.Example
Such as, current proximity values are 100, c=20%, then a=120%, b=80%, then set proximity values constant interval is
[80,120], then upper boundary values are 120, lower border value 80, by the 120 upper limit threshold write-in as first kind decision threshold
The threshold register of proximity sensor is written in proximity sensor, by the 80 lower threshold write-in as first kind decision threshold
Proximity sensor.
Step 103 receives in close/separate Status Change that proximity sensor is generated based on first kind decision threshold
When disconnected, enable preset threshold dynamic adjustment algorithm and dynamic tune is carried out to the upper limit threshold and lower threshold of first kind decision threshold
It is whole, obtain the second class decision threshold.
Illustratively, when receive that proximity sensor generated based on first kind decision threshold close to/become far from state
When more interrupting, it can illustrate that biggish variation has occurred in proximity values, preset threshold dynamic adjustment algorithm can be started at this time to the first kind
The upper limit threshold and lower threshold of decision threshold carry out dynamic adjustment, obtain the second class decision threshold.Preset threshold dynamic adjusts
Algorithm may include according to use state of environmental factor, the working condition of proximity sensor itself or user etc. come to decision threshold
Value carries out the algorithm of dynamic adjustment.For example, environmental factor may include ambient light intensity etc. for infrared proximity transducer；
The working condition of proximity sensor itself may include proximity sensor surface with the presence or absence of chaff interferents such as greasy dirts；User's uses shape
State may include judging whether the distance between proximity sensor and user are less than pre-determined distance value etc..The present embodiment is to default threshold
The specific calculation of value dynamic adjustment algorithm is not construed as limiting.It, can be very fast after preset threshold dynamic adjustment algorithm is activated

Proximity sensor processed is carried out based on the second class decision threshold close to the/judgement far from state.By using above-mentioned technical side
Case enables preset threshold dynamic adjustment algorithm just when proximity values change a lot to determine decision threshold, avoids frequently fast
Data are written into threshold register for fast ground, can reduce the burden of system, and then save mobile terminal power consumption, can also reduce close
The loss of sensor chip.

Step 203, receive that proximity sensor generated based on first kind decision threshold close to/far from Status Change
When interruption, forbid reporting close/separate Status Change event to upper layer.
In existing scheme, mobile terminal receive that proximity sensor generated based on decision threshold close to/it is separate
When Status Change is interrupted, need to report close/separate Status Change event to upper layer (such as application layer), so that mobile terminal execution
Corresponding operation, such as put out screen or bright screen.Wherein, close to/far from Status Change event include two kinds of altering events, i.e., by
Become the altering event of proximity state far from state and the altering event far from state is become from proximity state.The embodiment of the present invention
In first kind decision threshold be not actually in order to determine close to/far from state, but in order to judge the variation of proximity values
Whether certain range is had exceeded, so generating close/separate state when proximity sensor is based on first kind decision threshold and becoming
When more interrupting, it can be shown that close/separate state does not change currently, be only possible to change in a short time, institute
To need to forbid reporting close/separate Status Change event to upper layer, prevent mobile terminal execution corresponding with the change terminal
It operates and causes close to/erroneous judgement the problem far from state.
Preferably, receive that proximity sensor generated based on first kind decision threshold close to/far from Status Change
After interruption, it may also include control proximity sensor and nullify close/separate Status Change generated based on first kind decision threshold
It interrupts.It for most proximity sensor chips, is alternately produced close to far from change interruption, i.e., if current generate
(hereinafter referred to as close to interrupt) is interrupted in change from becoming proximity state far from state, then can only generate by approaching next time
State becomes the change far from state and interrupts (hereinafter referred to as far from interruption), and vice versa.Assuming that being based on first kind decision threshold
It producing close to interruption, can illustrate that proximity values increasing degree is larger, have close to trend, mobile terminal is likely to have close to movement,
It is carried out based on the second class decision threshold close to when/judgement far from state in subsequent step, it is likely that need to generate again and connect
It is close to interrupt, so eliminating this proximity state machine at this time close to interruption cancellation.The present embodiment is nullified specific
Mode is not construed as limiting, and can be determined according to specific chip type.For example, can be infused by operating the enable bit of proximity sensor
(reopen and close a proximity sensor) is interrupted in pin change, and the status register etc. for changing interruption also can be read
Deng.

It will be interrupted referred to as from the change for becoming proximity state far from state close to interrupting, will be become from proximity state below
Change far from state is interrupted referred to as far from interrupting, will be referred to as close from the altering event for becoming proximity state far from state
Event will become the altering event far from state referred to as far from event from proximity state.
Correspondingly, the method for the present embodiment includes the following steps:
Step 301, detect proximity sensor starting when, initial decision threshold is set.
Illustratively, proximity sensor starting can be regarded as proximity sensor and be enabled, i.e., some application program is to close
Sensor is called and opens proximity sensor.Initial decision threshold includes initial upper limit threshold value and initial lower threshold,
It can be arranged by system default.
Step 302, when determining that current state is far from state based on initial decision threshold, obtain working as proximity sensor
Preceding proximity values.
In general, user, during using mobile terminal, external object is in relative to proximity sensor far from shape

Step 304, receive that proximity sensor generated based on first kind decision threshold close to/far from interrupting when,
Forbid reporting close/separate event to upper layer, and controls proximity sensor and nullify based on first kind decision threshold connecing for generating
Closely/far from interruption.
Step 305 enables preset threshold dynamic adjustment algorithm to the upper limit threshold and lower threshold of first kind decision threshold
Dynamic adjustment is carried out, the second class decision threshold is obtained.
Step 306, control proximity sensor are carried out based on the second class decision threshold close to the/judgement far from state.
Step 307 is receiving that proximity sensor generated based on the second class decision threshold close to when interruption, to upper layer
It reports close to event, and terminates the operation of preset threshold dynamic adjustment algorithm, continue control proximity sensor and sentenced based on the second class
Determine threshold value to carry out close to/the judgement far from state.
It should be noted that the algorithm is real time execution after preset threshold dynamic adjustment algorithm is activated, so the
Two class decision thresholds are constantly to obtain dynamically adjusting according to situations such as environment, device working condition and user's use state
, namely receiving that proximity sensor generated based on the second class decision threshold close to before interruption, preset threshold dynamic
Adjustment algorithm can dynamically calculate the second class decision threshold, be produced until receiving proximity sensor based on the second class decision threshold
It is raw close to when interruption, terminate the operation of preset threshold dynamic adjustment algorithm.Then, keep the second class decision threshold constant, and
Continue to control the judgement that proximity sensor carries out close/separate state based on the second class decision threshold.
Step 308, when receiving the separate interruption that proximity sensor is generated based on the second class decision threshold, to upper layer
It reports far from event.
Step 309, the current proximity values for obtaining proximity sensor, and return to step 303.
Preferably, it can be opened at the time of receiving the separate interruption that proximity sensor is generated based on the second class decision threshold
The current proximity values of proximity sensor are obtained after the waiting preset duration that begins.The advantages of this arrangement are as follows separate just generating
When interruption, since proximity values have just reached far from threshold value, proximity values at this time compare with entirely without the proximity values under occlusion state
For it is larger, proximity values may become smaller rapidly in a short time, thus wait preset duration after, can reach substantially entirely without
Occlusion state, proximity values constant interval is set according to proximity values at this time can more reasonably judge that the variation of proximity values becomes
Gesture also can more reasonably judge from the trend for becoming proximity state far from state.
In the present embodiment, only setting proximity values constant interval according to current proximity values under far from state is advantageous in that,
For user during using mobile terminal, moving distance is longer when often becoming proximity state from separate state, it is easier to sentence
Moving distance is shorter when breaking and the variation tendency of proximity values, and becoming from proximity state far from state, for judging that proximity values become
The time of change trend is less, fast and accurately determines so the method for the present embodiment can guarantee far from event.
The control method for the proximity sensor that the embodiment of the present invention three provides, under far from state, when proximity values occur one
Preset threshold dynamic adjustment algorithm is just enabled when changing surely and determines decision threshold, is avoided frequent rapidly into threshold register
Data are written, can reduce the burden of system, and then save mobile terminal power consumption, can also reduce the loss of proximity sensor chip.
