Technical field
The present invention relates to equipment debugging technical field, particularly relate to calibration steps and the system of proximity transducer.
Background technology
For the terminal device possessing touch-screen (such as capacitance touch screen mobile phone), be easy to cause maloperation because of the touching of user, such as, when using mobile phone to make a phone call, be easy to cause maloperation because of the touching of face.Therefore, in order to solve problems, current section terminating equipment occurs proximity transducer, when object proximity terminal device being detected, triggering terminal equipment carries out corresponding protection act to avoid maloperation.Proximity transducer comprises infrared transmitter and multiple infrared remote receiver, the infrared light that infrared transmitter is launched is received by infrared remote receiver after reflections off objects, therefore by the infrared intensity value variation tendency of checking infrared remote receiver just can judgment object whether close.Due to terminal device structure and select chip to there is various deviation when dispatching from the factory, these deviations can cause when not having object near proximity transducer, the infrared intensity value of each infrared remote receiver is all different, like this in the use procedure of proximity transducer, the reference value of each infrared remote receiver is just different, easily causes judgement to make mistakes.Therefore when dispatching from the factory, under engineering mode, all can there is a process of calibrating, its objective is and allow the infrared intensity value of each infrared remote receiver be consistent.Current calibration process is also fairly simple, calibrates respectively exactly, deduct deviate to each infrared remote receiver, makes the infrared intensity value of each infrared remote receiver all the same, then deviate is preserved as calibration data.All calibration can be performed during each unlatching proximity transducer in terminal device; but; calibration operation can not be accomplished in one move; elapsed time is needed to go to perform; the calibration operation of current proximity transducer is all the calibration data based on preserving under engineering mode; in fact; proximity transducer often can be subject to the interference of the environmental factors such as greasy dirt; if calibration operation is all based on the calibration data preserved under engineering mode each time; the alignment time then can be caused partially long; the state reporting time of proximity transducer is also elongated, and the experience of user is deteriorated.
Summary of the invention
Based on this, for solving problems of the prior art, the invention provides a kind of calibration steps of proximity transducer, length according to the calibration used time judges that whether calibration data is preserved, for calibration operation provides effective data next time, thus shorten the alignment time, improve Consumer's Experience.
For achieving the above object, the present invention adopts following technical scheme:

Concrete, for mobile phone, when user with mobile phone receive calls, use the scenes such as blank screen gesture time, proximity transducer opened by mobile phone, first will perform calibration, now, mobile phone generates calibration command, after proximity transducer receives this calibration command, read the calibration data stored in mobile phone, and calibrate according to this calibration data.
Proximity transducer comprises infrared transmitter and infrared remote receiver, the infrared light that infrared transmitter is launched is received by infrared remote receiver after reflections off objects, therefore by the infrared intensity value variation tendency of checking infrared remote receiver just can judgment object whether close.In one embodiment, calibration data comprises the infrared intensity deviate of infrared remote receiver, under factory state, the infrared intensity deviate of each infrared remote receiver stored in mobile phone is the deviate offset recorded under engineering mode, but consider the impact of various environment for use factor, such as handset touch panel speckles with greasy dirt, dust, therefore still need to calibrate each use during proximity transducer.During each calibration, the whole deviation of the enterprising step in basis of the infrared intensity deviate of the infrared remote receiver stored in mobile phone, finally makes the infrared intensity value of each infrared remote receiver be consistent.
If calibrate complete, just obtain the calibration data of current generation, as mentioned above, this calibration data also comprises the deviate of each infrared remote receiver infrared intensity.After having calibrated, proximity transducer normally works, but the present invention also creatively judges the calibration used time, wherein, the calibration used time refers to that proximity transducer performs the time of calibrating and consuming, in a kind of embodiment, after receiving calibration command, open timer, after calibration completes, read the value of timer, the calibration used time can be obtained according to the value of this timer.In another kind of embodiment, also can judge to calibrate the used time according to system clock.The present invention is directed to calibration the used time threshold value is set, such as 50 milliseconds, if the current calibration used time is greater than threshold value, show that original calibration data (calibration data namely stored in terminal device) has not been suitable for the current environment for use of terminal device, such as terminal device touch screen surface speckles with greasy dirt, dust, to such an extent as to perform the overlong time of calibration, if still perform calibration on the basis of this original calibration data next time, so application proximity transducer is realized double-clicking bright screen, prevent the functions such as false triggering, the feedback speed of bottom data is just slack-off, causing bright screen etc. to respond also can be slack-off.Therefore, the present invention utilizes the calibration data of current generation (these data are applicable to the current environment for use of terminal device) to substitute original calibration data, completes the renewal of calibration data.When execution is calibrated, based on the calibration data after upgrading, thus shorten the alignment time next time, improve the response speed of proximity transducer, improve Consumer's Experience further.
In another specific embodiment, as shown in Figure 2, if calibrate complete and after obtaining the calibration data of current generation, if the calibration used time is less than or equal to threshold value, then abandon the calibration data of current generation.Because if the calibration used time is less than threshold value, then illustrate that original calibration data (calibration data namely stored in terminal device) can meet the requirement of proximity transducer response speed, be applicable to the environment for use that terminal device is current, perform when calibrating based on the calibration data that this is original next time, also can complete rapidly.
In sum, according to the length of calibration used time, the present invention judges that whether calibration data is preserved, when the calibration used time of proximity transducer is longer, original calibration data is substituted with the calibration data of current generation, realize the renewal of calibration data, for calibration operation provides the calibration data being more suitable for terminal device environment for use next time, thus shorten the alignment time next time, improve the response speed of proximity transducer, improve Consumer's Experience.
