Description
Technical Field
The invention relates to the technical field of terminals, in particular to a method and a device for detecting the state of a proximity sensor and a terminal.
Background
At present, the proximity sensor, as a standard configuration of the terminal, plays an important role in implementing functions such as turning on or off a screen, and automatically adjusting a backlight.
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.
To facilitate the determination of the proximity or the distance of the obstruction based on the proximity value, a proximity threshold and a distance threshold are typically set, the proximity threshold being greater than or equal to the distance threshold. And when the approach value is larger than the approach threshold value, the approach sensor generates an approach interruption and controls the screen to be extinguished. When the approach value is smaller than the approach threshold value, the approach sensor generates an approach interrupt, and the control screen is lighted.
However, in the process of implementing the invention, the inventor finds that the prior art has the following defects: when the proximity sensor is subjected to interference of radio frequency or the like, the proximity value becomes large. If the approach value is greater than the approach threshold, an approach interruption occurs, and the state of the proximity sensor cannot be accurately detected, resulting in an inability to accurately control the screen.

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 method for detecting a state of a proximity sensor, which is performed by a state detecting apparatus of the proximity sensor, where the apparatus is implemented by software and/or hardware according to an embodiment of the present invention; the device is configured in a terminal such as a mobile phone. In this embodiment, when the terminal is a mobile phone, optionally, the method may be applied to a call scenario and may also be applied to other scenarios.
As shown in fig. 1, the technical solution provided in this embodiment is as follows:
s110: detecting whether a proximity sensor reports a state of the proximity sensor.
In the present embodiment, the proximity sensor is capable of detecting a distance between the obstacle and the terminal, determining a proximity value of the current proximity sensor from the distance, and determining whether the proximity sensor is in a proximity state or a distant state from the proximity value. Wherein the state of the proximity sensor includes a proximity state and a distant state.
In this embodiment, whether the proximity sensor reports the state of the proximity sensor is determined by whether the processor receives the state information sent by the proximity sensor. Specifically, if the processor receives the state information sent by the proximity sensor, the reporting state is judged, and if the processor does not receive the state information sent by the proximity sensor, the reporting state is not judged. The state information includes a far state or a near state, and the like. And the detection method of whether the proximity sensor reports the status is not limited to the above method.
S120: and when detecting that the proximity sensor does not report the state, detecting whether the proximity sensor generates proximity interruption or not.
In the present embodiment, the proximity interruption is triggered by the proximity sensor based on the proximity values acquired a plurality of times in succession. Illustratively, the proximity interrupt is triggered to be generated by the proximity sensor based on proximity values acquired a plurality of times in succession, including: the proximity sensor generates a proximity interrupt when the proximity values acquired a plurality of consecutive times are each greater than a proximity threshold value. The approximate value may be obtained twice, three times, or other times. And other ways of triggering generation of the proximity interrupt are possible.
When the proximity sensor is interfered, the proximity value becomes large (e.g., easily interfered by radio frequency during a call). When the approach value is larger than the approach threshold value, approach interruption is generated, and the screen of the terminal is controlled to be extinguished, so that the problem of inaccurate control of on-off of the screen is caused. Therefore, the proximity sensor needs to acquire the proximity value a plurality of times in succession. Therefore, whether the approach interruption is generated or not is judged through the obtained approach values for multiple times, the state of the approach sensor subjected to interference can be accurately judged, and the phenomenon of inaccurate screen control caused by the abnormal state after the interference is avoided.
When the proximity sensor receives an enable signal sent by an upper system, the state of the proximity sensor, namely the far state and the near state, needs to be reported. Otherwise, the upper system defaults the state of the proximity sensor to the last state, which causes the problem of inaccurate screen control. If the proximity sensor does not report the state of the proximity sensor after receiving the enabling signal, the processor actively reads the current acquired proximity value of the proximity sensor, compares the proximity value with the proximity threshold value to obtain the state of the current proximity sensor, and reports the state of the proximity sensor to an upper system. The upper system may be a terminal system, or may be a processor configured with the upper system.
However, when the processor actively acquires the current proximity value of the proximity sensor, the processor may acquire the proximity value of the proximity sensor after being interfered, which may cause a wrong state determination of the proximity sensor, resulting in inaccurate screen control. Therefore, when the proximity sensor is detected not to report the state, whether the proximity sensor generates the proximity interruption or not is detected, and the situation that the state judgment of the proximity sensor is wrong due to the interfered proximity value is avoided. The processor may be a processor for managing sensors in the terminal, or may be another processor.
S130: determining a state of the proximity sensor according to the proximity interruption detection result.
In this embodiment, for example, the determining the state of the proximity sensor according to the proximity interruption detection result includes: determining that the proximity sensor is in a proximity state when it is detected that the proximity sensor generates a proximity interrupt; determining that the proximity sensor is in a distant state when it is detected that the proximity sensor does not generate a proximity interrupt.
In the method for detecting a state of a proximity sensor provided in this embodiment, when it is detected that the proximity sensor does not report a state, whether the proximity sensor triggers generation of a proximity interrupt based on proximity values obtained continuously for multiple times is detected, so as to determine the state of the proximity sensor. When the proximity sensor is interfered, the state of the proximity sensor can be accurately detected, and the condition that the state of the proximity sensor is abnormal due to interference is avoided.
Fig. 2 is a flowchart of a method for detecting a state of a proximity sensor according to another embodiment of the present invention, and as shown in fig. 2, after detecting that the proximity sensor does not report the state, the following operations are further performed:
actively forgoing reading the proximity value acquired by the proximity sensor.
Therefore, when the proximity sensor is detected not to report, the phenomenon that the state judgment of the proximity sensor is wrong due to the interfered proximity value is avoided by actively giving up reading the proximity value of the proximity sensor.
Further, before the detecting whether the proximity sensor reports the state of the proximity sensor, the following operations are also performed:
modifying a parameter of the proximity sensor that determines a number of proximity value acquisitions such that the proximity sensor acquires a proximity value a plurality of times.
Thus, by modifying the parameters of the proximity sensor so that the proximity sensor acquires the proximity value a plurality of times in succession, it is possible to prevent erroneous determination of the state of the proximity sensor.
Further, the method further comprises the following steps:
and reporting the state of the proximity sensor to an upper system so that the upper system controls a screen of the terminal based on the state.
The state of the proximity sensor is reported to the uploading system to control the screen, so that the screen can be automatically controlled.
As shown in fig. 2, the technical solution provided in this embodiment is as follows:
s210: the parameters of the proximity sensor for determining the number of times of proximity value acquisition are modified so that the proximity sensor acquires the proximity value a plurality of times in succession.
In the present embodiment, the parameter for determining the number of times of proximity value acquisition includes a persistence parameter of the proximity sensor. The persistence parameter of the proximity sensor is 1 as an original value, and the persistence parameter of the proximity sensor may be modified to 2, that is, the proximity sensor acquires the proximity value twice in succession. Or the persistence parameter of the proximity sensor can be modified to other values, so that the proximity sensor can acquire the proximity value for multiple times continuously as required.
In the present embodiment, the operation of modifying the parameter of the proximity sensor for determining the number of times of proximity value acquisition may be performed by the processor, may also be performed by the proximity sensor, or may also be performed by other devices within the terminal.
S220: detecting whether a proximity sensor reports a state of the proximity sensor.
S230: and actively giving up reading the proximity value acquired by the proximity sensor when the proximity sensor is detected not to report the state.
In this embodiment, the reading of the proximity value acquired by the proximity sensor is actively abandoned, that is, the proximity value acquired by the proximity sensor is not actively acquired. Therefore, when the processor detects that the proximity sensor does not report the state, the processor does not actively acquire the proximity value acquired by the proximity sensor and does not determine the state of the proximity sensor by comparing the acquired proximity value with the proximity threshold value, so that the situation of state misjudgment caused by abnormal proximity value after the proximity sensor is interfered is avoided.
S240: detecting whether the proximity sensor generates a proximity interrupt.
Wherein the proximity interrupt is triggered by the proximity sensor based on proximity values acquired a plurality of times in succession.
S250: determining a state of the proximity sensor according to the proximity interruption detection result.
S260: and reporting the state of the proximity sensor to an upper system so that the upper system controls a screen of the terminal based on the state.
In this embodiment, the upper system may be a terminal system, and the upper system may be configured in an upper processor.
In this embodiment, for example, the controlling, by the upper system, the screen of the terminal based on the state includes: when the state of the proximity sensor is in a proximity state, the screen of the control terminal is turned off; when the state of the proximity sensor is a distant state, the screen of the control terminal is lit.
In the present embodiment, the state detection of the proximity sensor of the present embodiment is exemplified, and for example, the proximity threshold is set to 200. At the current position, the state of the proximity sensor is judged through the proximity values acquired by the proximity sensor twice, if the proximity value acquired for the first time is 180, when the proximity value is acquired for the second time, the interference is caused, and the acquired proximity value is 240. In the prior art, when the proximity sensor does not report a state to the processor, if the proximity value actively read by the processor is 240, it is determined that the proximity sensor is in a proximity state, and the screen is controlled to be turned off. Since the proximity value actively read by the processor is a value after the proximity sensor is disturbed, the proximity value actively read by the processor is an abnormal value, and the state of the proximity sensor cannot be accurately determined (the state of the proximity sensor is actually a distant state).
In the embodiment of the invention, when the proximity sensor does not report the state to the processor, the processor does not actively read the proximity value acquired by the proximity sensor, but detects whether the proximity sensor generates the proximity interrupt. For the detection of the generation of the proximity interruption, the judgment is made by the proximity sensor by comparing the acquired proximity value twice with the proximity threshold value, that is, the proximity interruption is generated when both the proximity values (180 and 240) acquired by the proximity sensor are greater than the proximity threshold value (200). Therefore, when the proximity sensor acquires the proximity values of 180 and 240, respectively, through two times at the current position, the proximity interrupt is not generated. The processor detects that the proximity sensor does not generate a proximity interrupt, determines that the proximity sensor is in a far state (the same as the actual state of the proximity sensor at the current position), and controls the screen to be lightened so as to realize accurate control of the screen.
It should be noted that, in the present embodiment, the state detection method of the proximity sensor is performed by exemplarily combining S210-S260 as one example, but is only one example of the present invention, and in other embodiments of the present invention, S210 may also be combined with S110-S130 as one example to perform the state detection method of the proximity sensor, or S260 may also be combined with S110-S130 as one example to perform the state detection method of the proximity sensor, or S210-S250 may be combined with one example to perform the state detection method of the proximity sensor, or S220-S260 may also be combined with one example to perform the state detection method of the proximity sensor.
In the embodiment, when the proximity sensor is detected not to report, the phenomenon that the state judgment of the proximity sensor is wrong due to the interfered proximity value is avoided by actively giving up reading the proximity value of the proximity sensor; the parameters of the proximity sensor are modified to enable the proximity sensor to continuously acquire the proximity value for multiple times, so that the state of the proximity sensor can be prevented from being judged wrongly; the state of the proximity sensor is reported to the uploading system to control the screen, so that the screen can be automatically controlled.
Fig. 3 is a flowchart of a method for detecting a state of a proximity sensor according to another embodiment of the present invention, where, optionally, the operation of modifying a parameter of the proximity sensor for determining the number of times of obtaining a proximity value is performed by a processor. As shown in fig. 3, the technical solution provided in this embodiment is as follows:
s310: the processor modifies a parameter of the proximity sensor that is used to determine the number of proximity value acquisitions.
S320: the processor sends an instruction to the proximity sensor to control the proximity sensor to acquire the proximity value a plurality of times in succession.
S330: the proximity sensor acquires proximity values a plurality of times in succession according to the received instruction, and determines whether to generate a proximity interrupt based on the proximity values acquired a plurality of times in succession.
S340: the processor detects whether the proximity sensor reports the state of the proximity sensor.
S350: and when the processor detects that the proximity sensor does not report the state, actively abandoning to read the proximity value acquired by the proximity sensor.
S360: the processor sends a detection instruction to the proximity sensor to detect whether the interrupt occurs.
S370: the proximity sensor receives a detection instruction.
S380: the proximity sensor sends information to the processor whether a proximity interrupt is triggered.
S390: a processor detects whether the proximity sensor generates a proximity interrupt based on the received information.

S392: and the processor reports the state of the proximity sensor to an upper-layer system.
S393: and the upper system controls the screen of the terminal based on the state.
It should be noted that the method for detecting the state of the proximity sensor shown in fig. 3 is merely an example, and the order of the steps in the method shown in fig. 3 may be changed to achieve the purpose of detecting the state of the proximity sensor.
In this embodiment, when it is detected that the proximity sensor does not report a state, it is detected whether the proximity sensor triggers generation of a proximity interrupt based on proximity values acquired continuously for multiple times, so as to determine the state of the proximity sensor. When the proximity sensor is interfered, the state of the proximity sensor can be accurately detected, and the condition that the state of the proximity sensor is abnormal due to interference is avoided.
