The invention relates to the technical field of terminals, in particular to a threshold updating method and device of a proximity sensor and a terminal.
Background
The proximity sensor provided in the terminal is typically 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 shield and the 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 shield and the received infrared light.
In order to facilitate the judgment of the approach or the departure of the obstruction according to the approach value, a threshold value of the approach sensor is usually set, and the threshold value is often set in a dynamic manner, and the threshold value of the approach sensor is updated through the acquired approach value, namely the approach threshold value and the departure threshold value.

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 but not all of the relevant aspects of the present invention are shown in the drawings.
Fig. 1 is a flowchart of a threshold updating method for a proximity sensor, which is provided by an embodiment of the present invention, and is performed by a threshold updating apparatus for a proximity sensor, which is implemented by software and/or hardware, and which is generally configured in a terminal such as a mobile phone. When the terminal is a mobile phone, the method is applied to a conversation scene. As shown in fig. 1, the technical solution provided in this embodiment is as follows:
s110: when the proximity sensor is detected to be in a far state, the proximity value continuously acquired by the proximity sensor is recorded, and the continuous acquisition times are accumulated.
The threshold value of the proximity sensor is often set in a dynamic mode, namely the threshold value is determined according to the proximity value acquired by the proximity sensor in a far-away state, and because the acquired proximity value has a jumping range, the threshold value is inaccurate or unreasonable in setting due to the fact that the acquired proximity value determines the threshold value once, and inaccurate screen control is caused. Therefore, in this embodiment, when the proximity sensor is detected to be in the distant state, the proximity value continuously acquired by the proximity sensor is recorded and the number of times of continuous acquisition is accumulated, and the threshold value is determined based on the plurality of recorded continuously acquired proximity values.
In this embodiment, the detection that the proximity sensor is in the distant state is determined by the acquired proximity value and the threshold value determined last time. And when the acquired approach value is smaller than the last determined departure threshold value, determining that the approach sensor is in a departure state. The detection of the state of the proximity sensor may be detected by the processor or may be detected by other modules within the terminal.
S120: and if the continuous acquisition times reach the set times, updating the threshold value of the proximity sensor according to the recorded proximity value.
In this embodiment, the set number is a preset number, and can be set as needed. And when the proximity sensor is in a far state, if the continuous acquisition times reach the set times, determining an average value according to the recorded proximity value, and updating the threshold value of the proximity sensor according to the average value.
Specifically, if the number of continuous acquisition times reaches the set number of times, the recorded multiple approach values are summed, and an average value of the multiple approach values is obtained. And respectively adding a first constant and a second constant on the basis of the average value to respectively obtain a proximity threshold value and a distance threshold value of the proximity sensor.
For example, the number of times is set to 5, and when the proximity sensor is in the distant state and the number of continuous acquisition times reaches 5, the 5 acquired proximity values recorded are averaged, and the proximity threshold value and the distant threshold value of the proximity sensor are determined from the average value.
S130: when the approach sensor is detected to be switched from the far state to the approach state, the continuous acquisition times are reset so as to be accumulated again when the approach sensor is in the far state and the approach value is recorded again.
When the approach sensor is switched from a far state to an approach state, the approach value of the approach sensor is greatly changed due to the fact that the approach sensor is easily affected by oil stains. When the accumulated continuous acquisition times do not reach the set times, the proximity sensor needs to continuously acquire the proximity value after being switched from the proximity state to the distant state, and the threshold value is determined according to the acquired proximity value of the set times. Because the proximity sensor receives the influence of greasy dirt when being close to the state, consequently, when the proximity sensor switches to the state of being close to by far away from the state, need reset the continuous collection number of times that adds up, be about to continuous collection number of times clear to the continuous collection number of times and record the approximate value again of reincumulating when making the proximity sensor be in the state of keeping away from.
Or when the proximity sensor is switched from the far state to the near state, even if the continuous acquisition times reach the set times, the continuous acquisition times can be reset so as to accumulate the continuous acquisition times again and record the near value again when the proximity sensor is in the far state.
S140: and if the re-accumulated continuous acquisition times reach the set times, updating the threshold value of the proximity sensor based on the re-recorded proximity value.
In this embodiment, for example, if the number of times of continuous collection accumulated again reaches the set number of times, updating the threshold value of the proximity sensor based on the newly recorded proximity value includes: when the re-accumulated continuous acquisition times reach the set times, determining an average value according to the re-recorded approach value; updating a threshold of the proximity sensor based on the average. Wherein said updating the threshold of the proximity sensor according to the average value comprises: on the basis of the average value, a first constant and a second constant are respectively superimposed to obtain a proximity threshold value and a distance threshold value after the proximity sensor update.
In the method for updating the threshold of the proximity sensor provided by the embodiment, when the proximity sensor is detected to be in a far state and the recorded continuous acquisition times reach the set times, the threshold is updated according to the recorded proximity value; when the proximity sensor is detected to be switched from the far state to the near state, continuous acquisition times are accumulated again and the near value is recorded again by resetting the continuous acquisition times so that the proximity sensor is in the far state, when the accumulated continuous acquisition times reach the set times, the threshold value is updated based on the recorded near value, the threshold value of the proximity sensor can be accurately set, the control of the proximity screen is inaccurate, and the problem of inaccurate threshold value setting caused by the influence of oil stains on the proximity sensor is avoided.
Fig. 2 is a flowchart of a threshold updating method for a proximity sensor according to an embodiment of the present invention, and on the basis of the above embodiment, optionally, the resetting the consecutive acquisition times when the proximity sensor is detected to switch from the far state to the near state to enable the proximity sensor to be in the far state and to re-accumulate the consecutive acquisition times and re-record the proximity value includes:
when the proximity sensor is detected to be switched from a far state to a near state and the continuous acquisition times do not reach the set times, resetting the continuous acquisition times so as to accumulate the continuous acquisition times again and record the acquired near value again when the proximity sensor is in the far state.
From this, through when detecting proximity sensor by keeping away from the state and switching to the state of being close, and when the number of times of gathering in succession did not reach the settlement number of times, reset the number of times of gathering in succession, can avoid the threshold value that the greasy dirt leads to the proximity sensor to confirm the inaccurate condition, solve the inaccurate problem of screen control.
Based on the above optimization, as shown in fig. 2, the technical solution provided in this embodiment is specifically as follows:
s210: when the proximity sensor is detected to be in a far state, the proximity value continuously acquired by the proximity sensor is recorded, and the continuous acquisition times are accumulated.
S220: and if the continuous acquisition times reach the set times, updating the threshold value of the proximity sensor according to the recorded proximity value.
S230: when the proximity sensor is detected to be switched from a far state to a near state and the continuous acquisition times do not reach the set times, resetting the continuous acquisition times so as to accumulate the continuous acquisition times again and record the acquired near value again when the proximity sensor is in the far state.
In this embodiment, when it is detected that the proximity sensor is switched from the distant state to the proximate state, and the accumulated consecutive acquisition times does not reach the set times, the consecutive acquisition times needs to be reset, so that the situation that the acquisition times are continuously accumulated on the basis of the previously accumulated consecutive acquisition times when the proximity sensor is switched to the distant state again is avoided, and the problem that the threshold value is set inaccurately due to the influence of oil stains on the proximity sensor under the condition that the threshold value is determined based on the recorded consecutive acquired proximity value is avoided.
For example, if the set number of times is 5, that is, when the proximity sensor is in the distant state, the threshold value of the proximity sensor is determined by recording the proximity values acquired 5 times in succession. If the proximity sensor is switched from the distant state to the proximity state, the accumulated number of continuous acquisition times is 3, and the proximity values of 3 times recorded without reaching the set number (5 times) are 100, 102 and 105, respectively. If the proximity sensor is affected by oil contamination in a proximity state, the upper limit value of the oil contamination threshold value set at this time is 850, and the lower limit value of the oil contamination threshold value is 800. The upper limit value of the oil stain threshold value is the sum of the approaching value of the current approaching sensor and the maximum variation of the approaching value caused by the oil stain, and the lower limit value of the oil stain threshold value is the difference between the upper limit value of the oil stain threshold value and a constant. When the approach value of the approach sensor is smaller than the lower limit value of the oil stain threshold value, the approach sensor is in a far-away state, and when the approach value of the approach sensor is larger than the upper limit value of the oil stain threshold value, the approach sensor is in an approach state. And when the proximity sensor is in the proximity state, the proximity value of the proximity sensor is not recorded, that is, the threshold value is not determined by the proximity value in the proximity state.
When the proximity sensor is switched from the proximity state to the remote state, and the proximity sensor is in the remote state again, if the continuous acquisition times are not reset, the continuous acquisition times are continuously accumulated on the basis of the previous 3 times, and the set times (5 times) can be reached by accumulating 2 times. And the recorded proximity values of the proximity sensors for 2 consecutive acquisitions are 500, 600, respectively. The proximity sensor threshold is determined from the proximity values (100, 105) recorded the first 3 times (unaffected by oil contamination) and the proximity values (500 and 600) recorded the 2 times after being affected by oil contamination. Since 500 and 600 are the proximity values recorded in the case where the proximity sensor is affected by oil contamination, the change from the proximity value recorded the previous 3 times is large, and thus the determined threshold value of the proximity sensor is inaccurate.
Therefore, when the proximity sensor is switched from the distant state to the proximity state and the number of continuous acquisitions does not reach the set number, the number of continuous acquisitions needs to be reset. When the proximity sensor is switched from the proximity state to the far state and the proximity sensor is in the far state again, the continuous acquisition times are accumulated again and the proximity value is recorded again. Specifically, after the number of continuous acquisition times is reset, when the proximity sensor is in the distant state again, the proximity value is acquired for 5 times again, and the proximity value is recorded, and if the recorded proximity values are 500, 600, 400, 450, and 550, respectively, the threshold value of the proximity sensor is updated by the newly recorded proximity value, thereby improving the accuracy of setting the threshold value. By calculation, the average value of 500, 600, 400, 450, 550 is 500. If the first constant (80) is added to 500, the approach threshold (580) is obtained, and if the second constant (40) is added to 500, the departure threshold (540) is obtained. If the approach value of the proximity sensor is 450 in the process of the next approach to the distance from the proximity sensor, which is less than the distance threshold, the screen should be bright.
However, if the number of continuous acquisition is not reset when the proximity sensor is switched from the distant state to the close state, the average value calculated by 100, 105, 500, 600 is 282, the determined distant threshold is 322, and the determined close threshold is 362, and if the proximity value of the proximity sensor is 450, 450 is greater than the distant threshold, the control screen is turned off, resulting in inaccurate screen control. Therefore, when the proximity sensor is switched from the distant state to the proximity state and the number of continuous acquisitions does not reach the set number, the number of continuous acquisitions needs to be reset.
S240: and if the re-accumulated continuous acquisition times reach the set times, updating the threshold value of the proximity sensor based on the re-recorded proximity value.
According to the threshold updating method for the proximity sensor, when the proximity sensor is detected to be switched from the far state to the close state and the continuous collection times do not reach the set times, the continuous collection times are reset, the condition that threshold determination is inaccurate due to the influence of oil stains on the proximity sensor can be avoided, and the problem of inaccurate screen control is solved.
Fig. 3 is a flowchart of a threshold updating method for a proximity sensor according to another embodiment of the present invention, on the basis of the above embodiment, after the threshold of the proximity sensor is updated according to the recorded proximity value when the number of consecutive acquisitions reaches the set number, the following operations are further performed:
resetting the number of consecutive acquisitions to reincumulate the number of consecutive acquisitions when the proximity sensor is in the far state.
Therefore, the continuous acquisition times are reset after the threshold value of the proximity sensor is updated, so that the proximity sensor periodically and continuously acquires the proximity value to continuously update the threshold value, the threshold value of the proximity sensor is accurately set, and the problem of inaccurate screen control is avoided.
Correspondingly, as shown in fig. 3, the technical solution provided by this embodiment is as follows:
s310: when the proximity sensor is detected to be in a far state, the proximity value continuously acquired by the proximity sensor is recorded, and the continuous acquisition times are accumulated.
S320: and if the continuous acquisition times reach the set times, updating the threshold value of the proximity sensor according to the recorded proximity value.
S330: when the approach sensor is detected to be switched from the far state to the approach state, the continuous acquisition times are reset so as to be accumulated again when the approach sensor is in the far state and the approach value is recorded again.
S340: and if the re-accumulated continuous acquisition times reach the set times, updating the threshold value of the proximity sensor based on the re-recorded proximity value.
S350: resetting the number of consecutive acquisitions to reincumulate the number of consecutive acquisitions when the proximity sensor is in the far state.
In this embodiment, if the re-accumulated continuous acquisition times reaches the set times, after the threshold of the proximity sensor is updated based on the re-recorded proximity value, the continuous acquisition times need to be reset so that the continuous acquisition times are re-accumulated when the proximity sensor is in a distant state, and the proximity value is re-recorded, thereby periodically and continuously updating the threshold of the proximity sensor. Or when the continuous acquisition times reach the set times, resetting the continuous acquisition times so as to lead the proximity sensor to periodically and continuously update the threshold value.
In this embodiment, for example, if the set number of times is 5. When the proximity sensor is in a far state and the accumulated continuous acquisition times reach 5 times, updating the threshold value of the proximity sensor according to the recorded 5 proximity values, then resetting the continuous acquisition times, namely resetting the continuous acquisition times, accumulating the continuous acquisition times again, recording the proximity values again and periodically updating the threshold value of the proximity sensor.
In the embodiment of the present invention, S310 to S350 are exemplarily combined into an example to perform a threshold updating method of a proximity sensor, but the embodiment is only an example of the present invention, and in other embodiments of the present invention, S350 may also be combined with S210 to S240 into an example to perform a threshold updating method of a proximity sensor.
According to the threshold updating method of the proximity sensor, the number of continuous acquisition times is reset after the threshold of the proximity sensor is updated, so that the proximity sensor periodically and continuously acquires the proximity value to continuously update the threshold, the threshold of the proximity sensor is accurately set, and the problem of inaccurate screen control is avoided.
