Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are for purposes of illustration and not limitation. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of a method for calibrating a proximity sensor parameter according to an embodiment of the present application, which is applicable to calibrating a proximity sensor, and the method may be executed by a terminal device according to an embodiment of the present application, where a proximity sensor parameter calibration apparatus of the terminal device may be implemented in a software and/or hardware manner, as shown in fig. 1, a specific scheme provided in this embodiment is as follows:
and step S101, writing the first calibration parameter value into a parameter data set of the nonvolatile file.
In one embodiment, the proximity sensor is disposed above a screen of the terminal device, and may be an infrared proximity sensor, where the infrared proximity sensor includes an infrared transmitting tube and an infrared receiving tube, the infrared transmitting tube transmits infrared light outwards along the screen direction, the infrared receiving tube receives the infrared light reflected by the shielding object and converts the infrared light into an electrical signal, the electrical signal is amplified and analog-to-digital converted (a/D converted) processed to obtain a digital signal corresponding to the intensity of the reflected infrared light and then sent to the CPU, and the CPU determines whether the terminal device is in a shielding state according to the digital signal. Above-mentioned function is in the use, because the difference of terminal equipment place environment, like under outdoor highlight environment, the infrared light intensity that infrared receiving tube received this moment is strong when being in under the dark place environment than terminal equipment, if, again, terminal equipment pad pasting or be infected with after oil stain, also can have great error to the judgement of proximity sensor's the state of sheltering from, consequently need calibrate so that under different environmental conditions, proximity sensor's function keeps normally to the proximity sensor parameter.
The non-volatile file may be an NV (non-volatile) file of the terminal device, and the content in the NV file is not changed by operations such as shutdown, total clearing, and system upgrade of the terminal device. The first calibration parameter value may be written as an initial calibration value for proximity sensor parameter calibration into a parameter dataset of the non-volatile file, which may also contain calibration parameters for other sensors, the first calibration parameter recorded in the parameter dataset being used for subsequent calibration comparisons.
In an embodiment, the first calibration parameter value may be a calibration parameter value obtained by calibrating the proximity sensor when the terminal device leaves a factory. When the terminal device leaves the factory, hardware and software are required to be tested, and parameters of the proximity sensor are required to be calibrated so that the terminal device meets the factory requirements. The calibration parameter value obtained at the time of factory calibration may be determined as a first calibration parameter value, which may be, for example, 5, 6, or 15.
Step S102, when the generation of a second calibration parameter value is detected, acquiring the first calibration parameter value, and determining whether the difference value between the first calibration parameter value and the second calibration parameter value meets the updating condition of the calibration parameter value.
The terminal equipment can perform self-calibration of the parameters of the proximity sensor in the subsequent use process, the self-calibration can be a self-calibration mode integrated in the terminal equipment, and also can be a self-calibration function developed and accessed by a third party developer, and the functions of the proximity sensor can be kept normal under any environmental conditions through the self-calibration of the parameters of the proximity sensor. In one embodiment, the proximity sensor parameters are updated after self-calibration is completed, and the calibration process may be affected by many uncontrollable factors, so that the calibrated parameters have large deviation, and the proximity sensor fails to function if the parameters are directly updated.
In an embodiment, the second calibration parameter value may be a calibration parameter value obtained by a self-calibration manner of a proximity sensor carried by the terminal device, and when the second calibration parameter value is generated, a first calibration parameter value is obtained, and it is determined whether a difference between the first calibration parameter value and the second calibration parameter value satisfies a calibration parameter value update condition, where the first calibration parameter value may be a calibration parameter value stored in a parameter data set of an NV file, and specifically, whether the difference satisfies the calibration parameter value update condition includes: whether the absolute value of the difference is less than or equal to a preset update value, which may be 10, the second calibration parameter value may be-30, 5, 8, 10, 20, etc.
And step S103, if the calibration parameter value updating condition is not met, determining the first calibration parameter value as the current calibration parameter of the proximity sensor.
In one embodiment, when it is determined that the difference between the obtained second calibration parameter value and the first calibration parameter value does not satisfy the calibration parameter value updating condition, the previously stored first calibration parameter value is used as the current calibration parameter of the proximity sensor, that is, the calibration parameter value is not updated. And if the updating condition of the calibration parameter value is met, determining the second calibration parameter value as the current calibration parameter of the proximity sensor, and storing the second calibration parameter value in the parameter data set to replace the first calibration parameter value for comparison during subsequent calibration parameter value updating.
According to the method, when the terminal equipment generates a new calibration parameter, the calibration parameter value is compared with the stored calibration parameter value, if the updating condition is not met, the original stored calibration parameter value is continuously used for calibrating the proximity sensor parameter, and if the updating condition is met, the new calibration parameter value is used for updating the proximity sensor calibration parameter, so that the rationality of the proximity sensor parameter calibration is improved, and the parameter calibration function of the proximity sensor is perfected.
Fig. 2 is a flowchart of another proximity sensor parameter calibration method provided in an embodiment of the present application, and optionally before detecting generation of a second calibration parameter value, the method further includes: when a start-up event is detected, the proximity sensor parameters are calibrated to generate second calibration parameter values. As shown in fig. 2, the technical solution is as follows:
step S201, carrying out factory calibration of the proximity sensor parameters, and determining a first calibration parameter value.
Step S202, writing the first calibration parameter value into a parameter data set of the nonvolatile file.
Step S203, when the startup event is detected, calibrating the proximity sensor parameter to generate a second calibration parameter value.
In an embodiment, when the terminal device is switched from the power-off state to the power-on state, a second calibration parameter value is obtained when the proximity sensor is calibrated, where the second calibration parameter value may be a calibration parameter value obtained by first self-calibrating the proximity sensor after the terminal device is powered on each time.
Step S204, obtaining the first calibration parameter value, and determining whether the difference value between the first calibration parameter value and the second calibration parameter value meets the calibration parameter value updating condition.
The calibration parameter value updating condition may be the same as the calibration parameter value updating condition in step S102, and is not described herein again.
And S205, if the updating condition of the calibration parameter value is met, determining the second calibration parameter value as the current calibration parameter of the proximity sensor.
Step S206, saving the second calibration parameter value in the parameter data set to replace the first calibration parameter value.
In one embodiment, when the second calibration parameter value satisfies the update condition, the calibration parameter is replaced in the calibration parameter set, and the original first calibration parameter value is replaced by the second calibration parameter value.
Therefore, in the parameter calibration process of the proximity sensor, the parameter values meeting the updating conditions are updated and stored in the calibration parameter set, so that the calibration result is in a reasonable range every time, and the problem of failure of the proximity judgment function caused by the fact that the calibration parameters of the proximity sensor are modified due to mis-calibration or overlarge deviation of the calibration parameter values is avoided.

And S305, if the calibration parameter value updating condition is met, determining the second calibration parameter value as the current calibration parameter of the proximity sensor.
Step S306, saving the second calibration parameter value in the parameter data set in place of the first calibration parameter value.
And step S307, when the function of the proximity sensor is detected to be started, calibrating the proximity sensor parameter to generate a third calibration parameter value.
In one embodiment, when the proximity sensor starts to operate each time or performs calibration once every preset time, a third calibration parameter value is generated, and a specific calibration manner may exemplarily be: when the shielding is detected, the real-time infrared signal acquired by the proximity sensor is acquired, the real-time infrared signal and the oil stain threshold value are compared, when the real-time infrared signal is larger than or equal to the oil stain threshold value, oil stain is judged to be present, a corrected value (such as 50) is obtained through calculation, and the value-50 of the currently acquired real-time infrared signal is used as a third calibration parameter value.
Step S308, obtaining a second calibration parameter value stored in the parameter data set, if a difference between the stored calibration parameter value and the third calibration parameter value satisfies a calibration parameter value updating condition, determining the third calibration value as a current calibration parameter close to the sensor, and updating the calibration parameter value stored in the parameter data set.
According to the method, the calibration parameter value can be generated according to the existing calibration mode in the using process of the proximity sensor, whether the calibration parameter value meets the updating condition or not is judged, if yes, the calibration parameter value is updated and stored for subsequent comparison, the problem of proximity function failure caused by fluctuation change of the calibration parameter is reduced, meanwhile, the calibration parameter value can be updated in an iterative mode, the calibration parameter value is updated within a certain change range, and the calibration precision is improved.
