Referring to fig. 3, fig. 3 provides a dynamic antenna adjustment method, which is implemented in the electronic device shown in fig. 1 or fig. 2, where the electronic device includes a plurality of antennas, a touch display screen, a sensor, and a processor, the processor is connected to the touch display screen and the sensor, and the sensor can be used to detect parameters during a call, such as a distance, a position, and the like of an obstacle during the call, as shown in fig. 3, and the method includes the following steps:

step S301, during voice call, the electronic equipment detects the signal intensity of a first antenna of the voice call and whether a touch display screen is in a screen-off state;

the voice communication in step S301 may be implemented by using a communication standard or a protocol, where the communication standard or the protocol includes, but is not limited to, any one or any combination of Global System for Mobile communication (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), and Long Term Evolution (LTE).

The screen-off state in this step is to avoid executing DAT switching during hands-free, because if the voice call is in the hands-free state or is not answered by the handset, the signal strength of each antenna is generally good at this time, so that it is not necessary to activate DAT to increase extra overhead at this time, and it has a certain practical meaning only to activate DAT in the screen-off state.

Step S302, if the signal intensity is lower than the signal threshold value and the touch display screen is in a screen-off state, the electronic equipment acquires at least two distance levels between the remaining at least two antennas and the obstacle;

the above-mentioned manner of at least two distance levels between the remaining at least two antennas of the electronic device and the obstacle in step S302 includes, but is not limited to: detecting at least two levels of distance between the at least two antennas and the obstruction by a sensor including, but not limited to: one or any combination of an ultrasonic sensor, a proximity sensor or an infrared sensor.

Step S303, the electronic device determines priorities of the at least two antennas according to the at least two distance levels, and the electronic device performs DAT switching for the voice call according to the priorities.

According to the technical scheme, when voice call is carried out, whether the signal intensity of the first antenna for detecting the signal intensity of the voice call and the touch display screen are in the screen-off state or not is detected, if the signal intensity is lower than a signal threshold value and is in the screen-off state, the distance grade between the residual antennas (at least two or more than two antennas) and the obstacle is detected, the priority of the antennas is determined according to the distance grade, the antennas with the highest priority are selected by the electronic equipment to serve as the switching antennas of the voice call, the antennas after switching are far away from the obstacle, the influence of the obstacle on the signal quality of the antennas is avoided, the voice call quality is improved, and the user experience degree is improved.

Optionally, the determining, by the electronic device, the priority of the at least two antennas according to the at least two distance levels may specifically include:

the electronic device determines the priority of the at least two antennas according to the positive sequence of the at least two distance levels. Specifically, taking three antennas as an example, the distance levels of the three antennas are respectively, the distance level is low (the corresponding distance is short), the distance level is medium (the corresponding distance is moderate), and the distance level is high (the corresponding distance is long), and the priorities of the three antennas determined according to the positive sequence of the distance levels of the three antennas respectively correspond to: the priority is low, and the priority neutralization priority is high.

The principle of the method is that the distance between the antenna and the obstacle has the largest influence on the signal strength of the antenna, and for the influence, the technical scheme provided by the application determines the distance grade between the remaining antenna and the obstacle, wherein the distance grade is determined mainly because if the cost required for determining the accurate distance between the antenna and the obstacle is high, the space of the electronic equipment is limited, and an excessive number of sensors cannot be configured, so that the priority is determined to be most suitable by the distance grade.

Optionally, if the antenna with the highest priority is one, the electronic device switches the first antenna for the voice call to the second antenna through the DAT, where the second antenna is the antenna with the highest priority of the at least two antennas.

Optionally, if the antennas with the highest priority are multiple antennas, the electronic device obtains the coordinate of the current location, determines a geographic range of the coordinate according to the coordinate (which may be set by a user, for example, a circle of 10 meters with the coordinate as a center of the circle, or may be in other manners, for example, a building name corresponding to the coordinate, such as a company address of the user, determines the geographic range as a geographic range of a company), finds, according to the geographic range, first history switching information matched with the geographic range from the history switching information, obtains an antenna identifier in the first history switching information, finds, from the antennas with the highest priority, a third antenna matched with the antenna identifier, and starts a DAT to switch the voice call to the third antenna.

The finding of the first historical switching information matching the geographic range from the historical switching information may specifically include:

and searching the historical switching information for the first historical switching information within the geographic range.

Optionally, if the electronic device includes an ultrasonic sensor and an angle sensor, the electronic device detecting at least two distance levels between the remaining at least two antennas and the obstacle specifically includes:

the method comprises the steps of determining an ultrasonic sensor closest to any one of at least two antennas, detecting the angle of the electronic equipment by the angle sensor, controlling the ultrasonic sensor to emit an ultrasonic signal in a first time interval if the angle changes, wherein the starting time of the first time interval is a first time t1 when the angle changes, the duration of the first time interval is a set value (for example, 2 seconds), receiving a reflected signal of the ultrasonic signal, collecting n signal strength values in the reflected signal, and determining that the distance grade belongs to the lowest grade (specifically, the distance grade can be low) if the absolute value of the difference between the maximum value and the minimum value in the n signal strength values is lower than a difference threshold and the average value of the n signal strength values is greater than the signal strength threshold. The value of n is an integer greater than or equal to 2. If the absolute value of the maximum value and the minimum value in the n signal intensity values is higher than the difference threshold value and the average value of the n signal intensity values is larger than the signal intensity threshold value, the distance is determined to belong to the middle level (namely, the distance is moderate), and if the absolute value of the maximum value and the minimum value in the n signal intensity values is lower than the difference threshold value and the average value of the n signal intensity values is smaller than the signal intensity threshold value, the distance is determined to belong to the highest level (namely, the distance is larger).

The technical scheme that the ultrasonic sensor that the antenna is nearest is confirmed to this application, when angle sensor detects the angle change, sends ultrasonic signal, and receive ultrasonic reflection signal, gathers n signal strength values of reflection signal, confirms the influence of angle to the barrier according to the absolute value of the difference between the maximum value and the minimum value of these n signal strength values and the average value of n signal strength value and judges the grade that its distance belongs to. The reason for this is that, for the ultrasonic signal and the reflected signal, the reflected signal is generally reflected by an obstacle on a plane perpendicular to the ultrasonic signal, and the angle greatly affects the change of the intensity of the transmitted signal, and the technical scheme of the present application selects a first time interval of angle change, in which the angle between the ultrasonic sensor on the electronic device and the obstacle changes due to the change of the angle of the electronic device, in which case the distance of the obstacle is generally far from the electronic device, and because of the obstacle at a far distance, the area of a vertical plane with respect to the ultrasonic signal changes after the angle of the electronic device changes, and the area change is mainly represented by the decrease or increase of the signal intensity on the reflected signal. In another case, the first distance between the obstacle and the electronic device is very small, and in this case, after the angle of the electronic device changes, since the angle is very close to the obstacle, the area of the vertical plane with respect to the ultrasonic signal does not change much, and the signal intensity is substantially unchanged in the expression of the reflected signal, that is, the absolute value of the difference between the maximum value and the minimum value of the n signal intensity values is lower than the difference threshold. In addition, there is a case where the area of the obstacle is large but the distance is relatively long, and in this case, the change in the angle of the electronic device has little influence on the area of the vertical surface of the obstacle, but since the distance is relatively long, the average value of the signal strength of the reflected signal is relatively small due to the long transmission distance, and therefore the above-mentioned scheme excludes this case by the feature that the average value of the n signal strength values is larger than the signal strength threshold value. The distance level is determined by setting the situation to be very close to the obstacle by the above-described setting of the two directions, i.e., the setting in which the absolute value of the difference between the maximum value and the minimum value among the n signal intensity values is lower than the difference threshold and the average value of the n signal intensity values is larger than the signal intensity threshold.

Optionally, if the electronic device includes an ultrasonic sensor, an angle sensor, and a positioning sensor, the detecting, by the electronic device, at least two distance levels between the remaining at least two antennas and the obstacle specifically includes:

determining an ultrasonic sensor closest to any one of at least two antennas, detecting the angle of the electronic device by the angle sensor, if the frequency of the angle change is higher than a frequency threshold, controlling the ultrasonic sensor to emit an ultrasonic signal in a second time interval, if the starting time of the second time interval is a second time t1 when the frequency of the angle change is higher than the frequency threshold, and the duration of the second time interval is a set value (for example, 2 seconds), receiving a reflected signal of the ultrasonic signal, collecting m signal strength values in the reflected signal, if the absolute value of the difference between the maximum value and the minimum value in the m signal strength values is lower than a difference threshold and the average value of the m signal strength values is greater than the signal strength threshold, determining that the distance belongs to the lowest level (the distance is small), if the absolute value of the maximum value and the minimum value in the m signal strength values is greater than or equal to 2, and if the absolute value of the maximum value and the minimum value in the m signal strength values If the absolute value of the maximum value and the minimum value in the m signal strength values is lower than the difference threshold value and the average value of the m signal strength values is smaller than the signal strength threshold value, the distance is determined to belong to the highest grade (namely, the distance is larger).

According to the technical scheme, when the angle sensor detects the angle change, whether the frequency of the angle change is higher than a frequency threshold value or not is detected, if the frequency of the angle change is higher than the frequency threshold value, the ultrasonic signal is transmitted in a second time interval, the ultrasonic reflection signal is received, n signal intensity values of the reflection signal are collected, the influence of the angle on an obstacle is determined according to the absolute value of the difference value between the maximum value and the minimum value of the n signal intensity values and the average value of the n signal intensity values, whether the first distance of the obstacle is smaller than a distance threshold value or not is judged, and then whether a DAT is started or not is determined. The reason for this is that, for the ultrasonic signal and the reflected signal, the reflected signal is generally reflected by an obstacle on a plane perpendicular to the ultrasonic signal, and the angle greatly affects the change of the intensity of the transmitted signal, and the technical scheme of the present application selects a first time interval of angle change, in which the angle between the ultrasonic sensor on the electronic device and the obstacle changes due to the change of the angle of the electronic device, in which case the distance of the obstacle is generally far from the electronic device, and because of the obstacle at a far distance, the area of a vertical plane with respect to the ultrasonic signal changes after the angle of the electronic device changes, and the area change is mainly represented by the decrease or increase of the signal intensity on the reflected signal. In another case, the first distance between the obstacle and the electronic device is very small, and in this case, after the angle of the electronic device changes, since the angle is very close to the obstacle, the area of the vertical plane with respect to the ultrasonic signal does not change much, and the signal intensity is substantially unchanged in the expression of the reflected signal, that is, the absolute value of the difference between the maximum value and the minimum value among the m signal intensity values is lower than the difference threshold. In addition, there is a case where the area of the obstacle is large but the distance is relatively long, and in this case, the change in the angle of the electronic device has little influence on the area of the vertical surface of the obstacle, but since the distance is relatively long, the average value of the signal strength of the reflected signal is relatively small due to the long transmission distance, and therefore the above-mentioned scheme excludes this case by the feature that the average value of the m signal strength values is larger than the signal strength threshold value. Therefore, through the setting in the two directions, that is, if the absolute value of the difference between the maximum value and the minimum value in the m signal intensity values is lower than the difference threshold and the average value of the m signal intensity values is greater than the signal intensity threshold, the situation is set to be the situation where the obstacle is very close, so that a basis for judging the starting of the DAT is provided, unnecessary DAT switching can be reduced, voice call quality is improved, power consumption is reduced, and user experience is improved.
