It is to be understood that the objects so described are interchangeable under appropriate circumstances. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, or apparatus, terminal, system comprising a list of steps is not necessarily limited to those steps or modules or elements expressly listed, and may include other steps or modules or elements not expressly listed, or inherent to such process, method, apparatus, terminal, or system.
Embodiments of the present invention provide a proximity detection method, a proximity detection device, and a terminal, which will be described in detail below.
A proximity detection method may be applied in a terminal including a first signal transmitter, a second signal transmitter, and a signal receiver. The terminal can be a smart phone, a tablet computer and other devices.
As shown in fig. 1, the proximity detection method may include the steps of:
s110, the first signal emitter emits a detection signal, and the signal receiver obtains a first detection result.
And S120, the second signal emitter emits a detection signal, and the signal receiver acquires a second detection result.
In practical application, a proximity sensor is arranged on the terminal. The proximity sensor includes a signal transmitter and a signal receiver. The signal transmitter is used for transmitting signals, and the signal receiver is used for receiving reflected signals formed after the signals are reflected by external objects. The signal may be an optical signal or an acoustic signal. For example, the signal may be infrared light, laser light, or ultrasonic wave.
Referring to fig. 2 and 3, in the present embodiment, the proximity sensor includes a signal transmitter and a signal receiver. The signal transmitter comprises a first signal transmitter and a second signal transmitter, and the signal receiver comprises a first signal receiver and a second signal receiver. First, a first signal emitter emits a signal outwards. The signal is reflected by an external object to form a reflected signal. The first signal receiver and the second signal receiver receive the reflected signals, respectively. The distance between the first signal receiver and the first signal transmitter and the distance between the second signal receiver and the first signal transmitter are different, and therefore the signal strength received by the first signal receiver and the second signal receiver is different.
After the first signal receiver and the second signal receiver receive the reflected signals, a first detection result is obtained according to the received reflected signals. The detection result is in a close state or a distant state.
Then, the first signal emitter is turned off, and the second signal emitter is switched to emit signals outwards. Similarly, the signal is reflected by an external object to form a reflected signal. The first signal receiver and the second signal receiver receive the reflected signal. Moreover, the distance between the first signal receiver and the second signal transmitter is different from the distance between the second signal receiver and the second signal transmitter, so that the signal strength received by the first signal receiver and the second signal receiver is also different.
And after the first signal receiver and the second signal receiver receive the reflected signals, acquiring a second detection result according to the received reflected signals. The detection result is in a close state or a distant state.
Wherein a signal strength threshold may be set in the terminal in advance. When the signal intensity value received by the signal receiver is greater than or equal to the threshold value, the detection result is in an approaching state; when the signal intensity is smaller than the threshold value, the detection result is in a far state.
After the first signal receiver and the second signal receiver receive the reflected signals, the intensity of the received reflected signals is compared with the threshold value respectively to obtain respective detection results. When the detection result of at least one of the first signal receiver and the second signal receiver is in the proximity state, the detection result acquired by the signal receiver is in the proximity state. When the detection results of the first signal receiver and the second signal receiver are both in the remote state, the detection result acquired by the signal receiver is in the remote state.
In practical application, when the first signal transmitter transmits a detection signal, if a detection result of at least one of the first signal receiver and the second signal receiver is in a proximity state, the first detection result is in the proximity state; if the detection results of the first signal receiver and the second signal receiver are both in the remote state, the first detection result is in the remote state.
When the second signal emitter emits the detection signal, if the detection result of at least one of the first signal receiver and the second signal receiver is in the proximity state, the second detection result is in the proximity state; and if the detection results of the first signal receiver and the second signal receiver are both in the remote state, the second detection result is in the remote state.
For example, the preset signal strength threshold is 500. When the first signal transmitter transmits the probe signal, if the signal strength received by the first signal receiver is 600 and the signal strength received by the second signal receiver is 400, the detection result of the first signal receiver is in the close state and the detection result of the second signal receiver is in the far state. At this time, the first detection result is in a proximity state.
Referring to fig. 1 and 4 together, in some embodiments, before the second signal transmitter transmits the probe signal and the signal receiver obtains the second detection result, the proximity detection method may further include the following steps:
s150, acquiring the motion parameters of the terminal;
s160, judging whether the state of the terminal is changed according to the motion parameters;
if not, the second signal emitter emits a detection signal, and the signal receiver acquires a second detection result.
The motion parameters may include acceleration and angular velocity of the terminal, among others. The state of the terminal may include a position of the terminal and a posture of the terminal. In practical application, the terminal is provided with an acceleration sensor and a gyroscope. The acceleration sensor may be used to acquire an acceleration of the terminal. The gyroscope may be used to obtain the angular velocity of the terminal.
If the acceleration of the terminal changes, the speed of the terminal changes, that is, the position of the terminal changes. If the angular velocity of the terminal changes, the posture of the terminal changes. And after the terminal acquires the motion parameters, judging whether the motion parameters change. When neither the acceleration nor the angular velocity of the terminal has changed, it can be determined that the state of the terminal has not changed. Subsequently, the transmission of the probe signal by the first signal transmitter is switched to the transmission of the probe signal by the second signal transmitter. If the state of the terminal is determined to have changed, the process may be terminated and the proximity detection method may be restarted.
S130, judging whether the first detection result is the same as the second detection result to obtain a judgment result.
In practical application, after acquiring a first detection result and a second detection result, the terminal compares the first detection result with the second detection result to determine whether the first detection result and the second detection result are the same, and obtains a determination result.
And S140, determining the approaching or separating state between the terminal and the external object according to the judgment result.
In practical applications, after the determination result is obtained in S130, the terminal determines the approaching or departing state between the terminal and the external object according to the determination result.
In some embodiments, determining the approaching or departing state between the terminal and the external object according to the determination result may include:
s141, when the first detection result is the same as the second detection result, determining the first detection result or the second detection result as a close or distant state between the terminal and an external object;
s142, when the first detection result is different from the second detection result, the first signal transmitter and the second signal transmitter transmit the detection signal simultaneously, and the signal receiver obtains a third detection result;
s143, determining the third detection result as an approaching or separating state between the terminal and the external object.
In practical applications, when the first detection result is the same as the second detection result, any one of the first detection result and the second detection result may be determined as a close or distant state between the terminal and an external object. For example, if the first detection result and the second detection result are both in the proximity state, it may be determined that the terminal and the external object are in the proximity state.
Since the state of the terminal is not changed in the two detection processes, the two detection results should be the same theoretically. Therefore, when the first detection result and the second detection result are different, it can be understood that the detection result of one of them is inaccurate. At this time, the first signal emitter and the second signal emitter simultaneously emit the probe signal to perform the third detection. The signal receiver receives the reflected signal and obtains a third detection result. The process of obtaining the third detection result is substantially the same as the process of obtaining the first detection result and the second detection result, and is not described herein again.
And after the third detection result is obtained, determining the third detection result as the approaching or departing state between the terminal and the external object. For example, if the third detection result is a distant state, it may be determined that the terminal and the external object are in a distant state.
After the approaching or departing state between the terminal and the external object is determined, the terminal can be correspondingly controlled. For example, when the terminal is in a close state with an external object, the display screen can be turned off; when the terminal is far away from the external object, the display screen can be lightened.
In some embodiments, after determining the approaching or departing state between the terminal and the external object according to the determination result, the method may further include:
s170, comparing the third detection result with the first detection result to obtain a comparison result;
s171, when the third detection result is the same as the first detection result, determining that the second signal transmitter is malfunctioning;
and S172, when the third detection result is different from the first detection result, determining that the first signal transmitter has a fault.
In practical application, after the approaching or departing state between the terminal and the external object is determined, the third detection result is further compared with the first detection result. Since the first signal emitter and the second signal emitter are used simultaneously in the third detection process, it can be understood that the third detection result is accurate. When the third detection result is the same as the first detection result, indicating that the second detection result is inaccurate, it may be determined that the second signal transmitter is malfunctioning. When the third detection result is different from the first detection result, the first detection result is inaccurate, and the first signal transmitter is determined to be in fault.
In some embodiments, the third detection result may also be compared to the second detection result. When the third detection result is the same as the second detection result, indicating that the first detection result is inaccurate, it can be determined that the first signal transmitter is malfunctioning. When the third detection result is different from the second detection result, the second detection result is inaccurate, and the second signal transmitter can be determined to be in fault.
In some embodiments, after determining that the first signal transmitter is faulty or the second signal transmitter is faulty, the method may further include:
s180, acquiring preset prompt information;
and S190, displaying the preset prompt message on the terminal.
The preset prompting information can be information stored in the terminal memory in advance. The preset prompt message is used to cause a malfunction of a signal transmitter for use in the proximity sensor so that a user can take measures such as replacement or repair. For example, the preset prompting message may be "the signal transmitter is out of order, please replace in time", etc.
And after the terminal determines that the first signal transmitter fails or the second signal transmitter fails, calling the preset prompt information from a memory of the terminal, and displaying the preset prompt information on the terminal.
In particular, the present invention is not limited by the execution sequence of the steps, and some steps may be performed in other sequences or simultaneously without conflict.
As can be seen from the above, in the proximity detection method provided in the embodiment of the present invention, the first signal transmitter transmits the probe signal; the signal receiver acquires a first detection result; the second signal emitter emits a detection signal; the signal receiver acquires a second detection result; judging whether the first detection result is the same as the second detection result to obtain a judgment result; and determining the approaching or separating state between the terminal and the external object according to the judgment result. According to the scheme, the two signal transmitters are used for respectively transmitting the detection signals and respectively acquiring the detection results twice, the approaching or far-away state between the terminal and the external object is determined based on whether the detection results twice are the same, the inaccuracy of the detection result when a single signal transmitter is used can be avoided, and the accuracy of the approaching or far-away state between the detection terminal and the external object can be improved.
The embodiment of the invention also provides a proximity detection device, which can be applied to a terminal, wherein the terminal comprises a first signal transmitter, a second signal transmitter and a signal receiver. The terminal can be a smart phone, a tablet computer and other devices.
As shown in fig. 5, the proximity detection apparatus 200 may include: a first obtaining module 201, a second obtaining module 202, a first judging module 203, and a first determining module 204.
The first obtaining module 201 is configured to, when the first signal transmitter transmits the probe signal, obtain a first detection result by the signal receiver;
the second obtaining module 202 is configured to obtain a second detection result by the signal receiver when the second signal transmitter transmits the probe signal.
In practical application, a proximity sensor is arranged on the terminal. The proximity sensor includes a signal transmitter and a signal receiver. The signal transmitter is used for transmitting signals, and the signal receiver is used for receiving reflected signals formed after the signals are reflected by external objects. The signal may be an optical signal or an acoustic signal. For example, the signal may be infrared light, laser light, or ultrasonic wave.
In the present embodiment, the proximity sensor includes a signal transmitter and a signal receiver. The signal transmitter comprises a first signal transmitter and a second signal transmitter, and the signal receiver comprises a first signal receiver and a second signal receiver. First, a first signal emitter emits a signal outwards. The signal is reflected by an external object to form a reflected signal. The first signal receiver and the second signal receiver receive the reflected signals, respectively. The distance between the first signal receiver and the first signal transmitter and the distance between the second signal receiver and the first signal transmitter are different, and therefore the signal strength received by the first signal receiver and the second signal receiver is different.
After the first signal receiver and the second signal receiver receive the reflected signals, a first detection result is obtained according to the received reflected signals. The detection result is in a close state or a distant state.
Then, the first signal emitter is turned off, and the second signal emitter is switched to emit signals outwards. Similarly, the signal is reflected by an external object to form a reflected signal. The first signal receiver and the second signal receiver receive the reflected signal. Moreover, the distance between the first signal receiver and the second signal transmitter is different from the distance between the second signal receiver and the second signal transmitter, so that the signal strength received by the first signal receiver and the second signal receiver is also different.
And after the first signal receiver and the second signal receiver receive the reflected signals, acquiring a second detection result according to the received reflected signals. The detection result is in a close state or a distant state.
Wherein a signal strength threshold may be set in the terminal in advance. When the signal intensity value received by the signal receiver is greater than or equal to the threshold value, the detection result is in an approaching state; when the signal intensity is smaller than the threshold value, the detection result is in a far state.
After the first signal receiver and the second signal receiver receive the reflected signals, the intensity of the received reflected signals is compared with the threshold value respectively to obtain respective detection results. When the detection result of at least one of the first signal receiver and the second signal receiver is in the proximity state, the detection result acquired by the signal receiver is in the proximity state. When the detection results of the first signal receiver and the second signal receiver are both in the remote state, the detection result acquired by the signal receiver is in the remote state.
In practical application, when the first signal transmitter transmits a detection signal, if a detection result of at least one of the first signal receiver and the second signal receiver is in a proximity state, the first detection result is in the proximity state; if the detection results of the first signal receiver and the second signal receiver are both in the remote state, the first detection result is in the remote state.
When the second signal emitter emits the detection signal, if the detection result of at least one of the first signal receiver and the second signal receiver is in the proximity state, the second detection result is in the proximity state; and if the detection results of the first signal receiver and the second signal receiver are both in the remote state, the second detection result is in the remote state.
For example, the preset signal strength threshold is 500. When the first signal transmitter transmits the probe signal, if the signal strength received by the first signal receiver is 600 and the signal strength received by the second signal receiver is 400, the detection result of the first signal receiver is in the close state and the detection result of the second signal receiver is in the far state. At this time, the first detection result is in a proximity state.
In some embodiments, as shown in fig. 6, the proximity detection device further includes: a fourth obtaining module 205 and a second judging module 206.
The fourth obtaining module 205 is configured to obtain a motion parameter of the terminal;
the second determining module 206, configured to determine whether the state of the terminal changes according to the motion parameter;
the second obtaining module 202 is configured to, when the second determining module 206 determines that the second signal is not detected, transmit a probe signal by the second signal transmitter, and obtain a second detection result by the signal receiver.
The motion parameters may include acceleration and angular velocity of the terminal, among others. The state of the terminal may include a position of the terminal and a posture of the terminal. In practical application, the terminal is provided with an acceleration sensor and a gyroscope. The acceleration sensor may be used to acquire an acceleration of the terminal. The gyroscope may be used to obtain the angular velocity of the terminal.
If the acceleration of the terminal changes, the speed of the terminal changes, that is, the position of the terminal changes. If the angular velocity of the terminal changes, the posture of the terminal changes. After the fourth obtaining module 205 obtains the motion parameter of the terminal, the second determining module 206 determines whether the motion parameter changes. When neither the acceleration nor the angular velocity of the terminal has changed, it can be determined that the state of the terminal has not changed. Subsequently, the transmission of the probe signal by the first signal transmitter is switched to the transmission of the probe signal by the second signal transmitter. If the state of the terminal is determined to have changed, the process may be terminated and the proximity detection method may be restarted.
The first determining module 203 is configured to determine whether the first detection result is the same as the second detection result to obtain a determination result.
In practical applications, after obtaining the first detection result and the second detection result, the first determining module 203 compares the first detection result with the second detection result to determine whether the first detection result is the same as the second detection result, and obtains a determination result.
The first determining module 204 is configured to determine a proximity or a distance state between the terminal and the external object according to the determination result.
In practical applications, after the first determining module 203 obtains the determination result, the first determining module 204 determines the approaching or departing state between the terminal and the external object according to the determination result.
In some embodiments, the first determination module 204 is configured to perform the following steps:
determining the first detection result or the second detection result as a close or far state between the terminal and an external object when the first detection result is the same as the second detection result;
when the first detection result is different from the second detection result, the first signal transmitter and the second signal transmitter simultaneously transmit detection signals, and the signal receiver acquires a third detection result;

In practical applications, when the first detection result is the same as the second detection result, any one of the first detection result and the second detection result may be determined as a close or distant state between the terminal and an external object. For example, if the first detection result and the second detection result are both in the proximity state, it may be determined that the terminal and the external object are in the proximity state.
Since the state of the terminal is not changed in the two detection processes, the two detection results should be the same theoretically. Therefore, when the first detection result and the second detection result are different, it can be understood that the detection result of one of them is inaccurate. At this time, the first signal emitter and the second signal emitter simultaneously emit the probe signal to perform the third detection. The signal receiver receives the reflected signal and obtains a third detection result. The process of obtaining the third detection result is substantially the same as the process of obtaining the first detection result and the second detection result, and is not described herein again.
And after the third detection result is obtained, determining the third detection result as the approaching or departing state between the terminal and the external object.

For example, when the terminal is in a close state with an external object, the display screen can be turned off; when the terminal is far away from the external object, the display screen can be lightened.
In some embodiments, as shown in fig. 7, the proximity detection apparatus 200 further includes: a comparison module 207, a second determination module 208.
