Description
Technical Field
The embodiment of the invention relates to a mobile terminal technology, in particular to a control method and device based on a proximity sensor and a mobile terminal.
Background
At present, a proximity sensor, as a standard configuration of a mobile terminal, plays an important role in implementing functions such as turning on or off a display screen and automatically adjusting a backlight.
The proximity sensor provided in the mobile terminal is generally an infrared proximity sensor. The infrared proximity sensor includes an infrared transmitting tube and an infrared receiving tube. First, infrared light is emitted from an infrared emitting tube in the direction of the screen of the display screen. Then, the infrared receiving tube receives the infrared light reflected by the shielding object and converts the infrared light into an electric signal, the electric signal is amplified and subjected to analog-to-digital conversion (A/D conversion) to obtain a digital signal corresponding to the intensity of the reflected infrared light, and the digital signal is sent to the CPU, and the CPU takes the digital signal as a proximity value for further judgment. For example, the distance between the shielding object and the mobile terminal is determined by the proximity value, and the stronger the intensity of the received infrared light, the larger the proximity value, the smaller the distance between the shielding object and the shielding object.
In order to facilitate the judgment of the approaching or the departing of the obstruction according to the approaching value, a approaching threshold value and a departing threshold value are usually preset, wherein the approaching threshold value is greater than or equal to the departing threshold value. When the approach value is larger than the approach threshold value, judging that the obstruction is in an approach state; and when the approach value is smaller than the far threshold value, judging that the obstruction is in a far state. However, the above conclusion is obtained without considering a severe environment. In the process of implementing the invention, the inventor finds that under the strong light interference environment, the proximity sensor may generate a probabilistic overflow phenomenon because the infrared light received by the infrared receiving tube reaches a saturation value, so that the proximity value is returned to zero. And, in the electrostatic experiment process, the process progress of the infrared receiving tube may be interrupted due to electrostatic shock, so that the process progress is probabilistically interrupted, resulting in the near value being zeroed. When the approach value is zero, if a mode of determining the threshold value in the prior art (a mode of obtaining the approach threshold value and the distance threshold value at the next moment by superimposing a fixed value on the approach value at the current moment) is adopted, the obtained approach threshold value and the distance threshold value are very small. If the approach value at the next moment is recovered to the value in the normal state, the approach value at the next moment is larger than the determined approach threshold value, and the far state is directly and wrongly judged as the approach state, so that the state judgment at the next moment is influenced, and the state judgment is wrong.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of a proximity sensor-based control method according to an embodiment of the present invention, where the embodiment is applicable to a case where a proximity value sent by a proximity sensor is zero when a mobile terminal is in a strong light environment or an electrostatic experiment environment, and the method may be executed by a proximity sensor-based control device, where the device may be implemented by software and/or hardware, and may generally be integrated in the mobile terminal. As shown in fig. 1, the method specifically includes the following steps:
and step 110, acquiring a proximity value of the proximity sensor.
The proximity sensor is used for detecting whether the shielding object is in proximity relation or far-away relation with the mobile terminal. When the mobile terminal detects that the mobile terminal is in the proximity relation with the obstruction, the mobile terminal determines that the current obstruction is in the proximity state. Accordingly, when the mobile terminal detects that the mobile terminal is far away from the obstruction, the mobile terminal determines that the current obstruction is in a far away state. Illustratively, the proximity sensor may be an infrared proximity sensor. The infrared receiving tube receives the infrared light signal, converts the infrared light signal into an electric signal, and performs amplification, analog-to-digital conversion and other processing on the electric signal to obtain a proximity value of the infrared proximity sensor. The infrared light signal is converted into a digital signal, so that the mobile terminal CPU can conveniently judge the state of the shielding object according to the approach value. Therefore, the function of preventing false touch is automatically started according to the state of the shielding object, the function of automatically adjusting backlight is realized, and the like.
And step 120, judging whether the proximity sensor is in an abnormal state or not according to the proximity value.
Comparing the acquired approach value with zero, and if the approach value is equal to zero, determining that the proximity sensor is in an abnormal state at the current moment; otherwise, determining that the proximity sensor is in a normal state at the current moment.
When the proximity sensor is in a normal state at the current moment, in order to determine whether the shielding object is in a close state or a far state according to the proximity value, the mobile terminal automatically determines the judgment threshold value according to a set rule. The decision threshold value may be a value determined by the proximity value at the previous time.
Illustratively, the mobile terminal records the last time (t0) approaching value as 150, and superimposes the fixed values 40 and 60 on the last time (t0) approaching value to obtain the current time (t1) threshold value, i.e. the current time (t1) is far from the threshold value 190 and the current time (t1) is approaching the threshold value 210. If the approaching value at the current time (t1) is 200, which is larger than the distance threshold 190 but smaller than the approaching threshold 210, the determination result of the state of the obstacle at the previous time (t0) is kept unchanged. At this time, superimposing the reinforcement constants 40 and 60 on the basis of 200 results in the next time (t2) being far from the threshold 240 and the next time (t2) being close to the threshold 260. If the proximity value of 270 is exceeded by the proximity threshold value of 260 at the next time (t2), it is determined that an object is near the mobile terminal at the next time (t 2).
And step 130, when the proximity sensor is in an abnormal state, taking a preset highlight threshold as a judgment threshold of the next time of the abnormal state time, and determining the proximity state or the far state of the shielding object at the next time according to the judgment threshold.
The preset highlight threshold is larger than a normal threshold of the proximity sensor in a normal state. The normal threshold value of the proximity sensor in the normal state is obtained by superposing the proximity value of the previous moment on a set numerical value. The normal threshold value in the normal state may include a near threshold value N and a far threshold value F. The approach threshold value and the departure threshold value may be the same value (N ═ F). When the approaching threshold value and the far threshold value are not the same value, namely N is larger than F, when the approaching value is larger than the approaching threshold value N, it is judged that an object blocks light rays, namely the object is close to the mobile terminal; when the approach is smaller than the far threshold value F, the light shielding is eliminated, namely the object leaves the mobile terminal.
For example, when the approach value of the proximity sensor is zero, a preset highlight threshold value is used as a determination threshold value of the next time of the abnormal state time, so as to determine the approach state or the far state of the obstruction at the next time according to the determination threshold value. When factory setting is carried out, the preset highlight threshold value is determined according to the full scale of the proximity sensor, and the highlight threshold value comprises a proximity threshold value and a far threshold value. For example, the proximity sensor has a full scale of 1023, and the proximity threshold of the highlight threshold may be set to 950 and the distance threshold to 900. The advantage of this arrangement is that even at the time when the proximity sensor is in an abnormal state (the proximity value is zero), the highlight threshold value can be used as the determination threshold value at the next time, instead of determining the determination threshold value at the next time by superimposing the set value with the proximity value as in the prior art. If the proximity sensor returns to the normal state at the next moment, the situation that the far state is mistakenly judged as the close state does not occur.
According to the technical scheme of the embodiment, the approach value of the approach sensor is obtained; judging whether the proximity sensor is in an abnormal state or not according to the proximity value; and when the proximity sensor is in an abnormal state, taking a preset highlight threshold as a judgment threshold of the proximity sensor at the next moment of the abnormal state moment, and determining the proximity state or the far state of the shielding object at the next moment according to the judgment threshold, wherein the preset highlight threshold is larger than the normal threshold of the proximity sensor in the normal state. The problem that the judgment of the approaching state or the far-away state is disordered due to the fact that the approaching sensor is abnormal in the severe environment at present is solved, the situation that the judgment threshold value of the approaching sensor is wrong at the next moment due to the fact that the approaching value returns to zero in the strong light environment or the static experiment is avoided, the judgment accuracy of the approaching state or the far-away state in the severe environment is improved, and the probability that the approaching state or the far-away state is disordered is reduced.
Example two
Fig. 2 is a flowchart of another proximity sensor based control method according to a second embodiment of the present invention. On the basis of the foregoing technical solution, in the present embodiment, when the proximity sensor is in an abnormal state, after taking the preset highlight threshold as the determination threshold at the next time of the abnormal state time, the method may further include: judging whether the proximity sensor recovers to a normal state or not according to the proximity value at each moment after the abnormal state moment;
and when the proximity sensor recovers to the normal state, superposing the proximity value at the moment of recovering to the normal state with a set numerical value to obtain the judgment threshold value at the next moment of recovering to the normal state of the proximity sensor.
Based on the above optimization, as shown in fig. 2, the method of this embodiment specifically includes the following steps:
and 210, when the proximity sensor is in an abnormal state, taking a preset highlight threshold value as a judgment threshold value at the next moment of the abnormal state moment.
In step 220, the proximity value of the proximity sensor after the time of the abnormal state is acquired.
And when the proximity sensor is determined to be in the abnormal state, continuously acquiring the proximity value of the proximity sensor according to a set period.
Step 230, determining whether the approach value is equal to zero, if yes, performing step 240, otherwise, performing step 250.
The mobile terminal compares the proximity value with zero, and if the proximity value is equal to zero, step 240 is executed. If the approach value is not equal to zero, step 250 is performed.
The reason why the approach value is equal to zero may be that the proximity sensor is in a strong light environment, and infrared light in the environment is received by the infrared receiving tube after being superimposed with infrared light reflected by the blocking object. Since the received infrared light exceeds the saturation threshold of the infrared receiving tube, the infrared receiving tube will overflow probabilistically, and the approach value will be zero. It is also possible that the proximity sensor is in a strong electrostatic environment (e.g., an electrostatic experiment), and the integration process of the proximity sensor is affected due to electrostatic shock, so that the analog-to-digital conversion process is probabilistically interrupted, resulting in the proximity value being zeroed. Of course, it is also possible to zero the proximity value of the proximity sensor due to other factors, and is not limited to the two cases enumerated in the present embodiment.
And 240, determining that the proximity sensor is in an abnormal state.
When the approach value of the proximity sensor is zero, it is determined that the proximity sensor is in an abnormal state at this time, and the process proceeds to step 220.
And step 250, determining that the proximity sensor recovers to a normal state.
When the approach value of the proximity sensor is returned from zero to a non-zero value, it is determined that the proximity sensor is returned to a normal state at that time.
And step 260, superposing the proximity value at the moment of recovering to the normal state with a set numerical value to obtain a judgment threshold value at the next moment of recovering to the normal state of the proximity sensor.
And if the proximity sensor is determined to be recovered to the normal state, superposing the proximity value at the moment of recovering to the normal state and a set numerical value to obtain a judgment threshold value at the next moment of recovering to the normal state of the proximity sensor.
According to the technical scheme of the embodiment, whether the proximity sensor recovers the normal state is judged according to the proximity value of each time after the abnormal state time; when the proximity sensor returns to the normal state, the proximity value at the time of returning to the normal state is superposed with the set numerical value to obtain the judgment threshold value at the next time when the proximity sensor returns to the normal state, so as to judge the proximity state or the far state of the shielding object at the next time. The embodiment realizes that the determination mode of the judgment threshold value is adjusted after the proximity sensor recovers to the normal state, so that the situation that the proximity state of the shielding object is wrongly judged to be the far state due to the fact that the preset highlight threshold value is adopted as the judgment threshold value is avoided, the judgment accuracy of the proximity state or the far state when the proximity sensor is in the abnormal state is improved, and the problem that the proximity state or the far state is disordered when the proximity sensor recovers to the normal state is avoided.
EXAMPLE III
Fig. 3 is a flowchart of another proximity sensor based control method according to a third embodiment of the present invention. As shown in fig. 3, the method of this embodiment specifically includes the following steps:
in step 310, a proximity value of the proximity sensor is obtained.
And step 330, superposing the set numerical value on the approach value of the current moment to obtain the judgment threshold value of the next moment.
And when the proximity value is not zero, the mobile terminal determines that the proximity sensor is in a normal state. And determining the judgment threshold value of the next moment by adopting a mode of superposing the set numerical value on the approach value at the current moment, and turning to execute the step 360.
And 340, determining that the proximity sensor is in an abnormal state, and recording that the environment where the proximity sensor is located is a strong light interference environment or a static experiment environment.
When the proximity value is zero, the mobile terminal determines that the proximity sensor is in an abnormal state. The environmental flag for marking the environment is modified to a value corresponding to a strong light interference environment or an electrostatic experiment environment. For example, when the proximity sensor is in a strong light interference environment, the environmental flag may be preset to take a value of 1; when the proximity sensor is in the static experiment environment, the value of the environment mark is preset to be 2; and when the proximity sensor is in a normal state, the value of the environmental label is 0.
And step 350, taking the preset highlight threshold as a judgment threshold at the next moment of the abnormal state moment.
And when the mobile terminal determines that the proximity sensor is in an abnormal state, acquiring a preset highlight threshold value. And taking the highlight threshold as a judgment threshold at the next moment of the abnormal state moment. Wherein, the highlight threshold is larger than the normal threshold of the proximity sensor in the normal state.
And step 360, obtaining the current time judgment threshold value determined according to the last time approach value.
The mobile terminal obtains a current time judgment threshold value, wherein the current time judgment threshold value is determined by an approaching value at the previous time. When the last time approach value is zero, judging that the threshold value is a set highlight threshold value at the current time; and when the approach value at the previous moment is not zero, determining that the threshold value at the current moment is a superposition result of the approach value at the previous moment and the set data.
And 370, comparing the current time approaching value with the current time judging threshold value, and determining that the current shelter is in an approaching state or a departing state according to the comparison result.
Illustratively, the mobile terminal compares the current time proximity value with a current time decision threshold value. The current time threshold value comprises a close threshold value and a far threshold value. And when the approach value at the current moment is larger than the approach threshold value, determining that the current obstruction is in the approach state. And when the approach value at the current moment is smaller than the far threshold value, determining that the current obstruction is in a far state. And when the approach value at the current moment is between the approach threshold value and the departure threshold value, determining that the current obstruction keeps the same approach/departure state as the previous moment.
According to the technical scheme of the embodiment, the approach value of the approach sensor is obtained; judging whether the proximity sensor is in an abnormal state or not according to the proximity value; when the proximity sensor is in an abnormal state, taking a preset highlight threshold value as a judgment threshold value of the next time of the abnormal state time, and determining the proximity state or the far state of the shielding object at the next time according to the judgment threshold value; and acquiring a current time judgment threshold value determined according to the previous time approach value, and determining that the current obstruction is in an approach state or a far state according to the current time judgment threshold value. The method and the device solve the problem that judgment of the approaching state or the far state is disordered due to the abnormity of the approaching sensor in the current severe environment, avoid the condition that the judgment threshold value is wrong at the next moment due to the zeroing of the approaching value, improve the judgment accuracy of the approaching state or the far state in the severe environment, and reduce the probability that the approaching state or the far state is disordered.
