5 arbitrary integer.
Transmission power can be set several grades, be arranged according to power order from big to small.If first around
Value is penetrated more than preset value, then can be reached by reducing transmission power reduces the effect of the first diffraction value.Can first by transmitting
Transmission power one grade of reduction of device, and detect during using the transmission power transmitting infrared light reduced after a grade, connect
The received power value that units test is arrived is received, if the received power value is still above above-mentioned preset value, by above-mentioned ballistic device
Transmission power reduces a grade again, until when transmission power is reduced to target power, the infrared light that receiving device is received
Performance number be not more than above-mentioned preset value.
The transmission power of above-mentioned reduction ballistic device can be the driving current or reduction pulse by reducing transmitting fluorescent tube
Number come reach reduce ballistic device transmission power purpose.

Two threshold values are compared, wherein, the second diffraction value is that the ballistic device is infrared with the objective emission power emission
Light time, the performance number that the receiving device is detected, default first threshold value is more than default second threshold value；
If the performance number that the receiving device is received is more than first threshold value, the mobile terminal is controlled to put out screen；
If the performance number that the receiving device is received is less than second threshold value, above-mentioned mobile terminal bright screen is controlled.
Wherein, above-mentioned second diffraction value can be when transmission power is reduced to target work(by the ballistic device of proximity transducer
During rate, ballistic device launches infrared light, the performance number that receiving device is detected with target power.Second diffraction value can correspond to pre-
If the first threshold value and the second threshold value, first threshold value and the second threshold value can be respectively according to the second diffraction value meter
The value for calculating.
The current power value that receiving device is received compares with above-mentioned first threshold value and the second threshold value, judges current
Whether, more than the first threshold value or less than above-mentioned second threshold value, the first threshold value and the second threshold value can be respectively for performance number
It is proximate to threshold value and away from threshold value.If the current power value is more than first threshold value, it is believed that object is in
Near state, control mobile terminal puts out screen, to prevent the maloperation near generation of object；If the current power value is less than institute
State the second threshold value, it is believed that object is in away from state, maloperation will not occur in mobile terminal screen, control is mobile eventually
End bright screen.
In addition, when the transmission power of above-mentioned ballistic device is reduced to default minimum emissive power, proximity transducer connects
The diffraction value for receiving then can receive parameter still greater than above-mentioned preset value using default transmitting, can include transmission power
The transmission power that ballistic device is used for the first time is adjusted to open detection function.
In this embodiment, the received power value for proximity transducer being received is corresponding with the second diffraction value first
Limit value and the second threshold value are contrasted, and control mobile terminal puts out screen or bright screen, so, when user uses mobile terminal, Neng Goufang
Only object is close to and produces maloperation.
Optionally, the performance number that the receiving device is received default first thresholding corresponding with the second diffraction value
Value and default second threshold value are compared, including：
Determine the interval of default diffraction value residing for the second diffraction value；
The performance number that the receiving device is received default first threshold value corresponding with the interval and default second
Threshold value is compared.
In this embodiment, the second diffraction value is contrasted with the scope of default diffraction value, so that it is determined that second
The interval of the diffraction value residing for diffraction value.The current power value that the receiving device of proximity transducer is received and the second diffraction value
Whether interval corresponding first threshold value in place and the second threshold value are compared, judge current power value more than the first threshold value
Or can respectively be proximate to threshold value and away from thresholding less than above-mentioned second threshold value, the first threshold value and the second threshold value
Value.If current power value is more than first threshold value, it is believed that object is near state, and control mobile terminal puts out screen,
To prevent the maloperation near generation of object；If current power value is less than second threshold value, it is believed that object is in
Away from state, maloperation will not occur in mobile terminal screen, control mobile terminal bright screen.Wherein, first threshold value and
Two threshold values can be respectively the value calculated according to the second diffraction value.

Penetrate the corresponding screen door that puts out of value and be limited to 210, corresponding bright screen thresholding is 140.So, when proximity transducer receiving device is received
When performance number is more than 210, control mobile terminal puts out screen；When the performance number that proximity transducer receiving device is received is less than 140,
Control mobile terminal bright screen.
When the second diffraction value is 600, it is determined that the interval scope between 550 to 850 of residing diffraction value, the diffraction value
The corresponding screen door that puts out is limited to 680, and corresponding bright screen thresholding is 625.So, when the power that proximity transducer receiving device is received
When value is more than 680, control mobile terminal puts out screen；When the performance number that proximity transducer receiving device is received is less than 625, control
Mobile terminal bright screen.
In this embodiment, the interval of scope residing for the second diffraction value, the work(that the receiving device is received are determined
Rate value default first threshold value corresponding with the interval and default second threshold value are compared, in such manner, it is possible to improve compare
Efficiency, improve to mobile terminal screen put out screen or bright screen control efficiency, so as to improve the performance of proximity transducer.
The embodiment of the present invention on the basis of the corresponding embodiments of Fig. 1, when the diffraction value of continuous n times detection be both greater than it is described
During preset value, the transmission power of the ballistic device is reduced to objective emission power, can reduce that accidentalia causes is dry
Disturb, it is possible to increase the accuracy of testing result, improve the detection performance of proximity transducer.
