Therefore, an embodiment of the present application provides a method for switching antenna radiators, where the method is applied to the electronic device 100.

As shown in fig. 3, fig. 3 is a first flowchart of a method for switching an antenna radiator according to an embodiment of the present application, where the method for switching an antenna radiator includes:

110. detecting a current pose of the electronic device.

According to the usage habit of the user, the electronic device 100 can assume multiple postures during the usage, such as a vertical forward posture, a vertical reverse posture, a horizontal forward posture, and a horizontal reverse posture.

Taking the electronic device 100 shown in fig. 2 as an example, the horizontal height of the third side 103 is greater than the horizontal heights of the other three sides, and at this time, the posture of the electronic device 100 can be defined as the horizontal forward-direction placement posture. Based on the horizontal forward-oriented posture, the electronic device 100 shown in fig. 2 is rotated by 180 degrees, so that the horizontal height of the fourth side 104 is greater than the horizontal heights of the other three sides, and at this time, the posture of the electronic device 100 may be defined as the horizontal reverse-oriented posture. When the electronic device 100 shown in fig. 2 is rotated clockwise by 90 degrees, so that the horizontal height of the first side 101 is greater than the horizontal heights of the other three sides, at this time, the posture of the electronic device 100 may be defined as a vertical forward placement posture. With the vertical and forward placement posture as a reference, the electronic device 100 shown in fig. 2 is rotated 90 degrees counterclockwise, so that the horizontal height of the second side 102 is greater than the horizontal heights of the other three sides, and at this time, the posture of the electronic device 100 can be defined as a vertical and reverse placement posture.

The posture of the electronic apparatus 100 may be detected by a sensor such as a gravity sensor, an acceleration sensor, a gyroscope, or a magnetic sensor. For example, the gravity sensor or the acceleration sensor may measure acceleration due to gravity to calculate an inclination angle of the electronic device 100 with respect to a horizontal plane, so that the current posture of the electronic device 100 may be measured. The gyroscope may measure motions, such as rotation and deflection, of the electronic device 100, so as to accurately analyze an actual motion of a user, and further detect a current posture of the electronic device 100. The magnetic sensor may measure an azimuth, measure the azimuth of the electronic device 100 by using a geomagnetic field, and measure the current attitude of the electronic device 100 in cooperation with the gyroscope, the acceleration sensor, and the like.

It should be noted that the manner of measuring the current posture of the electronic device 100 in the present application is not limited to the above one or more sensing devices, and may also be a combination of a sensing device and related measurement software, and other methods that can measure the current posture of the electronic device 100 are all within the scope of the embodiments of the present application.

120. And determining three candidate antenna radiators from the at least four antenna radiators according to the current posture of the electronic equipment.

The attitude of the electronic device 100 is different, and the four GPS satellites have different capabilities of receiving GPS satellite signals. In the use process of the GPS satellite positioning system, in order to make GPS positioning more accurate, it is often necessary to select a GPS antenna radiator with a stronger ability to receive GPS satellite signals as a receiver of the GPS signals.

When the posture of the electronic device 100 is fixed, one GPS antenna radiator always exists among at least four GPS antenna radiators, and the GPS antenna radiator has the weakest ability to receive GPS satellite signals. In order to select an antenna radiator with a stronger satellite signal receiving capability, the electronic device 100 may select three candidate antenna radiators with a stronger satellite signal receiving capability from at least four GPS antenna radiators, and exclude the GPS antenna radiator with the weakest satellite signal receiving capability, where the satellite signal receiving capability of the three candidate antenna radiators is better than that of the remaining fourth antenna radiator in the current attitude.

130. Acquiring the signal intensity of at least one candidate antenna radiator;

140. and determining a target antenna radiator according to the signal strength, and receiving a GPS signal through the target antenna radiator.

When the electronic device 100 determines three candidate antenna radiators, the electronic device 100 may directly obtain the signal strength of one candidate antenna radiator from the three candidate antenna radiators, and when the signal strength satisfies the communication requirement, the electronic device 100 may directly use the candidate antenna radiator as a target antenna radiator, thereby greatly improving the antenna switching efficiency.

For the purpose of more accurate GPS positioning, when the electronic device 100 may further determine two or three candidate antenna radiators, the electronic device 100 controls the radio frequency switch 75 to alternately connect the candidate antenna radiators with the GPS chip 76 to form a plurality of GPS communication links, and by comparing level values on different communication links, the signal strength of the candidate antenna radiators may be compared, and then the candidate antenna radiator with the largest signal strength may be selected as a target antenna radiator, so that the positioning of the electronic device 100 is more accurate.

The electronic device 100 provided by the embodiment of the application includes at least four antenna radiators, each of which can be used to receive a GPS signal, and the antenna radiator switching method provided by the embodiment of the application first detects the current posture of the electronic device 100, and then determines three candidate antenna radiators from among the at least four antenna radiators according to the current posture of the electronic device 100; then, obtaining the signal intensity of at least one candidate antenna radiator; and finally, determining a target antenna radiator according to the signal strength, and receiving the GPS signal through the target antenna radiator. According to the electronic device and the switching method, the target antenna radiator is determined from the three candidate antenna radiators, the electronic device 100 does not need to detect the signal strength of at least four GPS antenna radiators in turn, and the antenna switching efficiency is improved. Moreover, switching among at least four antenna radiators can adapt to different postures of the electronic device 100, and the electronic device 100 can be accurately positioned in any posture.

Referring to fig. 4, fig. 4 is a second flowchart illustrating an antenna radiator switching method according to an embodiment of the present disclosure. Determining three candidate antenna radiators from the at least four antenna radiators according to the current attitude of the electronic device, including:

121. determining a reference side edge of the electronic equipment according to the current posture of the electronic equipment, wherein the reference side edge is the side edge with the highest horizontal height in the first side edge, the second side edge, the third side edge and the fourth side edge;

122. determining two side edges positioned on the reference side edge and adjacent to the reference side edge as three candidate side edges;

123. determining three candidate antenna radiators from all antenna radiators on the three candidate sides, wherein one candidate antenna radiator is arranged on each candidate side.

It is understood that the horizontal height of the first side 101, the second side 102, the third side 103 and the fourth side 104 may refer to the distance between the center point of the first side 101, the second side 102, the third side 103 and the fourth side 104 and the horizontal plane in the above-mentioned specific position of the electronic device 100. When the posture of the electronic device 100 changes, the horizontal height of the same side edge changes accordingly.

For example, when the electronic device 100 is in the vertical and forward posture, the horizontal height of the first side 101 is higher than the horizontal heights of the other three sides, and the first side 101 may be selected as the reference side. And, the third side 103 and the fourth side 104 located at two adjacent sides of the first side 101 may be selected as three candidate sides together with the first side 101. At this time, the patterns of the first, third, and fourth

GPS antenna radiators

71, 73, and 74 on the three candidate sides may be matched with the GPS satellites, and the electronic device 100 may determine the first, third, and fourth

GPS antenna radiators

71, 73, and 74 as the three candidate antenna radiators. Since the level of the second side 102 is less than the levels of the other three sides, and the directional pattern of the second GPS antenna radiator on the second side 102 does not match the GPS satellite, the electronic device 100 may consider only using the three candidate antenna radiators and not the second GPS antenna radiator 72 for receiving GPS satellite signals.

When the electronic device 100 is in the vertical reverse posture, the horizontal height of the second side 102 is higher than the horizontal heights of the other three sides, and the second side 102 may be selected as a reference side. And, a third side 103 and a fourth side 104 located at two adjacent sides of the second side 102 may be selected as three candidate sides together with the second side 102. At this time, the patterns of the second, third and fourth

GPS antenna radiators

72, 73 and 74 on the three candidate sides may be matched with the GPS satellites, and the electronic device 100 may determine the second, third and fourth

GPS antenna radiators

72, 73 and 74 as the three candidate antenna radiators. Since the level of the first side 101 is less than the levels of the other three sides, the directional pattern of the first GPS antenna radiator 71 on the first side 101 does not match the GPS satellite, and the electronic device 100 may consider only using the three candidate antenna radiators and not considering using the first GPS antenna radiator 71 to receive GPS satellite signals.

When the electronic device 100 is in the horizontal forward posture, the level of the third side 103 is higher than the levels of the other three sides, and the third side 103 may be selected as the reference side. And, the first side 101 and the second side 102 located at two adjacent sides of the third side 103 may be selected as three candidate sides together with the third side 103. At this time, the patterns of the third GPS antenna radiator 73, the first GPS antenna radiator 71, and the second GPS antenna radiator 72 on the three candidate sides may be matched with the GPS satellites, and the electronic device 100 may determine the third GPS antenna radiator 73, the first GPS antenna radiator 71, and the second GPS antenna radiator 72 as the three candidate antenna radiators. Since the level of the fourth side 104 is less than the levels of the other three sides, the directional pattern of the fourth GPS antenna radiator 74 on the fourth side 104 does not match the GPS satellite, and the electronic device 100 may consider only using the three candidate antenna radiators and not considering using the fourth GPS antenna radiator 74 to receive GPS satellite signals.

When the electronic device 100 is in the landscape orientation, the level of the fourth side 104 is higher than the levels of the other three sides, and the fourth side 104 may be selected as the reference side. Furthermore, the first side 101 and the second side 102 located at two adjacent sides of the fourth side 104 may be selected as three candidate sides together with the fourth side 104. At this time, the patterns of the fourth GPS antenna radiator 74, the first GPS antenna radiator 71, and the second GPS antenna radiator 72 located on the sides of the four candidates 104 may be matched with the GPS satellites, and the electronic device 100 may determine the fourth GPS antenna radiator 74, the first GPS antenna radiator 71, and the second GPS antenna radiator 72 as the three candidate antenna radiators. Since the third side 103 has a smaller horizontal height than the other three sides, the directional pattern of the third GPS antenna radiator 73 on the third side 103 does not match the GPS satellite, and the electronic device 100 may consider only using the three candidate antenna radiators and not the fourth GPS antenna radiator 74 for receiving GPS satellite signals.

It should be noted that the method for determining three candidate antenna radiators is not limited to the above example, and other methods may also be used, for example, a sensing device such as a gravity sensor, an acceleration sensor, a gyroscope, or the like inside the electronic device 100 is used to measure a motion parameter of each antenna radiator, and then three candidate antenna radiators are determined according to the relevant motion parameters.

It is understood that when the number of antenna radiators on the three candidate sides is greater than three, the electronic device 100 may select three radiators from the three candidate antenna radiators as three candidate antenna radiators. Specifically, the electronic device 100 may determine, according to the spatial parameter of each antenna radiator, the capability of the antenna radiator to receive the GPS signal, and select three antenna radiators with stronger capability as candidate antenna radiators. Of course, the electronic device 100 may also select the candidate antenna radiator with reference to the surrounding environment of each antenna radiator.

After determining that the antenna is located on the reference side of the electronic device 100 and the three GPS antenna radiators on the side adjacent to the reference side, the electronic device 100 may directly use the three GPS antenna radiators as candidate antenna radiators, and the electronic device 100 may directly control the radio frequency switch 75 to switch to the corresponding candidate antenna radiators in turn, and select the candidate antenna radiator with stronger signal strength as a target antenna radiator by comparing the level values of the three candidate antenna radiators, and utilize the target antenna radiator to receive GPS satellite signals.

Of course, the electronic device 100 may also gradually obtain the signal strength of the candidate antenna radiator. As shown in fig. 5, fig. 5 is a third flowchart illustrating an antenna radiator switching method according to an embodiment of the present application.

131. The electronic device may directly obtain a first signal strength of the candidate antenna radiator located on the reference side;

for example, the electronic device 100 may directly control the radio frequency switch 75 to electrically connect the candidate antenna radiator located on the reference side with the GPS chip 76 and form a communication link, obtain a first level value on the communication link, and reflect the first signal strength value by using the first level value.

It is to be understood that the method for measuring the first signal strength is not limited to the above example, and other methods, such as signal strength measurement software, signal strength measurement instrument, etc., may also be used to measure the magnitude of the first signal strength.

132. Judging whether the first signal intensity is larger than a preset signal intensity threshold value or not;

the preset signal strength threshold may be consistent with the measurement method of the first signal strength, for example, when the first signal strength is reflected by the first level value, the preset signal strength threshold may also be reflected by a level value of a communication link.

If so, stopping acquiring the signal strength of the candidate antenna radiator positioned on the adjacent side;

if the result of the determination is yes, it indicates that the candidate antenna radiator located on the reference side may meet the requirement of GPS positioning, and at this time, step 141 may be directly performed to determine the candidate antenna radiator located on the reference side as a target antenna radiator without acquiring signal strength of other candidate antenna radiators.

And if the judgment result is negative, continuously acquiring the signal strength of the candidate antenna radiator on at least one adjacent side.

If the determination result is negative, it indicates that the candidate antenna radiator located on the reference side cannot meet the requirement of GPS positioning, and in order to ensure accuracy of GPS positioning, the electronic device 100 needs to continuously obtain signal strength of other candidate antenna radiators, and needs to execute step 142 to determine the candidate antenna radiator with stronger signal strength as a target antenna radiator.

For example, when the posture of the electronic device 100 is a vertical forward posture, the horizontal height of the first side 101 is higher than the horizontal heights of the other three sides, and the electronic device 100 may control the radio frequency switch 75 to directly electrically connect the first GPS antenna radiator 71 located on the first side 101 and the GPS chip 76, so as to obtain the first signal strength of the first GPS antenna radiator 71. Then, judging whether the first signal intensity is greater than a preset signal intensity threshold value; if the determination result is yes, stopping acquiring the signal strength of the third GPS antenna radiator 73 and the fourth GPS antenna radiator 74 on the third side 103 and the fourth side 104; and directly using the first GPS antenna radiator 71 as a target antenna radiator, and receiving GPS satellite signals using the target antenna radiator. If the determination result is negative, the signal strength of at least one of the third GPS antenna radiator 73 and the fourth GPS antenna radiator 74 is continuously obtained.

When the posture of the electronic device 100 is a vertical reverse posture, the horizontal height of the second side 102 is higher than the horizontal heights of the other three sides, and the electronic device 100 may control the radio frequency switch 75 to directly electrically connect the second GPS antenna radiator 72 located on the second side 102 with the GPS chip 76, so as to obtain the signal strength of the second GPS antenna radiator 72. Then, judging whether the first signal intensity is greater than a preset signal intensity threshold value; if the determination result is yes, stopping acquiring the signal strength of the third GPS antenna radiator 73 and the fourth GPS antenna radiator 74 on the third side 103 and the fourth side 104; and directly uses the second GPS antenna radiator 72 as a target antenna radiator and receives GPS satellite signals using the target antenna radiator. If the determination result is negative, the signal strength of at least one of the third GPS antenna radiator 73 and the fourth GPS antenna radiator 74 is continuously obtained.

When the posture of the electronic device 100 is a horizontal forward posture, the horizontal height of the third side 103 is higher than the horizontal heights of the other three sides, and the electronic device 100 may control the radio frequency switch 75 to directly electrically connect the third GPS antenna radiator 73 located on the third side 103 and the GPS chip 76, so as to obtain the signal strength of the third GPS antenna radiator 73. Then, judging whether the first signal intensity is greater than a preset signal intensity threshold value; if the determination result is yes, stopping acquiring the signal strength of the first GPS antenna radiator 71 and the second GPS antenna radiator 72 on the first side 101 and the second side 102; and directly using the third GPS antenna radiator 73 as a target antenna radiator, and receiving a GPS satellite signal using the target antenna radiator. If the determination result is negative, the signal strength of at least one of the first GPS antenna radiator 71 and the second GPS antenna radiator 72 is continuously obtained.

When the electronic device 100 is in the horizontal reverse posture, the horizontal height of the fourth side 104 is higher than the horizontal heights of the other three sides, and the electronic device 100 may control the radio frequency switch 75 to directly electrically connect the fourth GPS antenna radiator 74 located on the fourth side 104 to the GPS chip 76, so as to obtain the signal strength of the fourth GPS antenna radiator 74. Then, judging whether the first signal intensity is greater than a preset signal intensity threshold value; if the determination result is yes, stopping acquiring the signal strength of the first GPS antenna radiator 71 and the second GPS antenna radiator 72 on the first side 101 and the second side 102; and directly uses the fourth GPS antenna radiator 74 as a target antenna radiator and receives GPS satellite signals using the target antenna radiator. If the determination result is negative, the signal strength of at least one of the first GPS antenna radiator 71 and the second GPS antenna radiator 72 is continuously obtained.

The antenna radiator switching method of the embodiment of the application directly obtains the signal strength of one antenna radiator, and when the candidate antenna radiator meets the communication requirement, the antenna radiator is directly used as a target antenna radiator, and the electronic device 100 does not need to detect the signal strength of three GPS antenna radiators in turn, thereby improving the antenna switching efficiency.

When the determination result is negative, in the step of continuously acquiring the signal strength of the candidate antenna radiators on at least one adjacent side, the electronic device 100 may further determine whether to acquire the signal strength of one or two of the candidate antenna radiators by detecting with a proximity sensor.

Specifically, the electronic device 100 may include a first proximity sensor, and the first proximity sensor may be configured to detect whether an obstacle is present near the electronic device 100. For example, the first proximity sensor may be a light sensor, and the light sensor may emit a detection light, and detect whether an obstacle exists by detecting an intensity of the reflected light; the first proximity sensor may also be an acoustic wave sensor, and the acoustic wave sensor emits a detection acoustic wave to detect whether an obstacle exists by detecting the intensity of the reflected acoustic wave. It is understood that the first proximity sensor is not limited to the above example, and other sensors capable of detecting whether an obstacle exists are within the scope of the present application.

The first proximity sensor may be mounted on the middle frame 30 or on the circuit board 40, and the first proximity sensor is electrically connected to the circuit board 40 to perform proximity detection. The first proximity sensor may be located on any one side of the electronic device 100 from the overall orientation of the electronic device 100, that is, the first proximity sensor may be located on the middle frame 30 or the circuit board 40 corresponding to the first side 101, the second side 102, the third side 103 and the fourth side 104.

With continued reference to fig. 5, the step of the electronic device 100 continuing to obtain the signal strength of the candidate antenna radiator on at least one adjacent side includes:

133. acquiring first position information of the first proximity sensor;

134. controlling the first proximity sensor to detect, and acquiring a first detection result of the proximity sensor;

135. and according to the first position information and the first detection result, continuously acquiring the signal strength of the candidate antenna radiator on one or two adjacent sides.

The first position information may be classified into first positive position information and first negative position information according to whether the side on which the first proximity sensor is located belongs to one of two adjacent sides. The first positive location information indicates that: the side where the first proximity sensor is located belongs to one of two adjacent sides; the first negative location information indicates: the side on which the first proximity sensor is located does not belong to one of the two adjacent sides.

The first detection result may be divided into a first positive result and a first negative result according to whether an obstacle is detected. The first positive result represents: the first proximity sensor detects an obstacle; the first negative result represents: the first proximity sensor does not detect an obstacle.

The first position information and the first detection result are different, and the number of the candidate antenna radiator signal strengths subsequently obtained by the electronic device 100 is also different.

Specifically, when the first location information is negative location information, it indicates that the side where the first proximity sensor is located is not located in two adjacent sides, that is, the antenna radiator located on the side where the first proximity sensor is located does not belong to a candidate antenna radiator, and at this time, the electronic device 100 may select an antenna radiator with a higher signal strength from among the three candidate antenna radiators as a target antenna radiator.

When the first location information is the first positive location information and the first detection result is the first positive result, the first location information and the first positive location information together may indicate that an obstacle exists on the side where the first proximity sensor is located, and the obstacle may greatly affect the capability of the GPS antenna radiator located on the side to receive GPS satellite signals, so that the electronic device 100 may directly obtain the second signal strength of the candidate antenna radiator on the remaining one adjacent side without considering the candidate antenna radiator on the adjacent side where the first proximity sensor is located. And the second signal strength may be compared with the first signal strength of the candidate antenna radiator located on the reference side, and the candidate antenna radiator having a greater signal strength may be selected as the target antenna radiator.

When the first location information is first positive location information and the first detection result is a first negative result, the first location information and the first negative result together may indicate that no obstacle exists on the side where the first proximity sensor is located, and further, the candidate antenna radiator located on the side where the first proximity sensor is located is not blocked by an obstacle, and the surrounding environment is good, at this time, the electronic device 100 needs to continue to acquire the signal strengths of two candidate antenna radiators on two adjacent sides, and then, the electronic device 100 compares the strengths of the three candidate antenna radiators and selects the candidate antenna radiator with a greater signal strength as the target antenna radiator.

According to the antenna radiator switching method, the number of the antenna radiators which are continuously acquired is judged by the first proximity sensor of the electronic device 100, on one hand, the proximity sensor does not need to be additionally arranged, the size of the electronic device 100 is not additionally occupied, on the other hand, the frequency that the electronic device 100 needs to acquire three candidate antenna radiators in turn can be reduced, and the antenna radiator switching efficiency can be improved.

In addition to the above method, the electronic device 100 may further adopt the following method to obtain the signal strength of at least one candidate antenna radiator, as shown in fig. 6, where fig. 6 is a fourth flowchart of the antenna radiator switching method provided in this embodiment of the present application.

The electronic device 100 may further include a second proximity sensor, which may also be used to detect whether an obstacle is present near the electronic device 100. For example, the second proximity sensor may be a light sensor, and the light sensor may emit a detection light to detect whether an obstacle exists by detecting the intensity of the reflected light; the second proximity sensor may also be an acoustic wave sensor, and the acoustic wave sensor emits a detection acoustic wave to detect whether an obstacle exists by detecting the intensity of the reflected acoustic wave. It is understood that the second proximity sensor is not limited to the above example, and other sensors capable of detecting whether an obstacle exists are within the scope of the present application.

The second proximity sensor may be mounted on the middle frame 30 or the circuit board 40, and the second proximity sensor is electrically connected to the circuit board 40 to perform proximity detection. The second proximity sensor may be located on any one side of the electronic device 100 from the overall orientation of the electronic device 100, that is, the second proximity sensor may be located on the middle frame 30 or the circuit board 40 corresponding to the first side 101, the second side 102, the third side 103 and the fourth side 104.

It is also understood that the second proximity sensor may be the same proximity sensor as the first proximity sensor, or the second proximity sensor may be a different proximity sensor from the first proximity sensor; the second proximity sensor may be located on the same side as the first proximity sensor, or the second proximity sensor may be located on a different side than the first proximity sensor.

Wherein the step of obtaining the signal strength in at least one of the candidate antenna radiators further comprises:

136. acquiring second position information of the second proximity sensor;

137. controlling the second proximity sensor to perform proximity detection and outputting a second detection result of the proximity sensor;

138. and acquiring the signal intensity in two or three candidate antenna radiators according to the second position information and the second detection result.

The second position information may be classified into second positive position information and second negative position information according to whether or not the side on which the second proximity sensor is located belongs to one of the three candidate sides. The second affirmative position information indicates: the side where the second proximity sensor is located belongs to the three candidate sides; the second negative position information indicates: the side where the second proximity sensor is located does not belong to the three candidate sides.

The second detection result may be divided into a second positive result and a second negative result according to whether an obstacle is detected. The second positive result represents: the second proximity sensor detects an obstacle; the second negative result represents: the first proximity sensor does not detect an obstacle.

The second position information is different from the second detection result, and the number of the candidate antenna radiator signal strengths subsequently obtained by the electronic device 100 is also different.

After the electronic device 100 obtains the signal strength of the two or three candidate antenna radiators, step 143 may be further performed to determine the candidate antenna radiator with the strongest signal strength of the two or three candidate antenna radiators as the target antenna radiator.

Specifically, when the second location information is negative location information, it indicates that the side where the second proximity sensor is located is not located in the three candidate sides, that is, the antenna radiator located on the side where the second proximity sensor is located does not belong to a candidate antenna radiator, and at this time, the electronic device 100 may select an antenna radiator with a higher signal strength from among the three candidate antenna radiators as a target antenna radiator.

When the second location information is the second positive location information and the second detection result is the second positive result, the two together may indicate that there is an obstacle on the side where the second proximity sensor is located, and the obstacle may greatly affect the capability of the GPS antenna radiator located on the side to receive GPS satellite signals, so that the electronic device 100 may directly obtain the signal strength of the candidate antenna radiators on the remaining two candidate sides without considering the candidate antenna radiators on the adjacent sides where the second proximity sensor is located. Then, the electronic device 100 may compare the signal strengths of the candidate antenna radiators on the remaining two candidate sides and select the candidate antenna radiator with the greater signal strength as the target antenna radiator.

When the second location information is second positive location information and the second detection result is a second negative result, the two may indicate that no obstacle exists on the side where the second proximity sensor is located, and further, the candidate antenna radiator located on the side where the second proximity sensor is located is not blocked by an obstacle, and the surrounding environment is good, at this time, the electronic device 100 needs to continue to obtain the signal strengths of the three candidate antenna radiators on the three candidate sides, and then, the electronic device 100 compares the strengths of the three candidate antenna radiators and selects the candidate antenna radiator with a greater signal strength as the target antenna radiator.

According to the antenna radiator switching method, the number of the antenna radiator signal strength which is continuously acquired is judged by the second proximity sensor of the electronic device 100, on one hand, the proximity sensor does not need to be additionally arranged, the size of the electronic device 100 is not additionally occupied, on the other hand, the frequency of the electronic device 100 which needs to acquire three candidate antenna radiator signal strengths in turn can be reduced, and the antenna radiator switching efficiency can be improved.

The embodiment of the present application further provides an antenna radiator switching device 200, which is applied to the electronic device 100. Referring to fig. 7, fig. 7 is a schematic structural diagram of an antenna radiator switching device according to an embodiment of the present application. The antenna radiator switching device 200 includes an attitude detection module 210, a candidate antenna radiator determination module 220, a signal strength acquisition module 230, and a target antenna radiator determination module 240.

Wherein the gesture detection module 210 is configured to detect a current gesture of the electronic device 100.

Taking the electronic device shown in fig. 2 as an example, the horizontal height of the third side 103 is greater than the horizontal heights of the other three sides, and in this case, the posture of the electronic device 100 can be defined as the horizontal forward-oriented posture. Taking the horizontal forward-oriented posture as an example, the electronic device 100 shown in fig. 2 is rotated by 180 degrees, so that the horizontal height of the fourth side 104 is greater than the horizontal heights of the other three sides, and at this time, the posture of the electronic device 100 may be defined as the horizontal reverse-oriented posture. The electronic device 100 shown in fig. 2 is rotated clockwise by 90 degrees, so that the horizontal height of the first side 101 is greater than the horizontal heights of the other three sides, and at this time, the posture of the electronic device 100 may be defined as a vertical forward placing posture. With the vertical and forward placement posture as a reference, the electronic device 100 shown in fig. 2 is rotated 90 degrees counterclockwise, so that the horizontal height of the second side 102 is greater than the horizontal heights of the other three sides, and at this time, the posture of the electronic device 100 can be defined as a vertical and reverse placement posture.

The gesture detection module 210 may detect the gesture of the electronic device 100 through a sensor such as a gravity sensor, an acceleration sensor, a gyroscope, or a magnetic sensor. For example, the gravity sensor or the acceleration sensor may measure acceleration due to gravity, and the posture detection module 210 may calculate an inclination angle of the electronic device 100 with respect to a horizontal plane according to the measured data, so as to measure a current posture of the electronic device 100. The gyroscope may measure motions, such as rotation and deflection, of the electronic device 100 to accurately analyze an actual motion of a user, and the gesture detection module 210 may detect a current gesture of the electronic device 100. The magnetic sensor may measure an azimuth, measure the azimuth of the electronic device 100 by using a geomagnetic field, and cooperate with the gyroscope, the acceleration sensor, and the like, the attitude detection module 210 may also measure the current attitude of the electronic device 100.

The candidate antenna radiator determining module 220 is configured to determine three candidate antenna radiators from the at least four antenna radiators according to the current posture of the electronic device.

The attitude of the electronic device 100 is different, and at least four of the GPS satellites have different capabilities for receiving GPS satellite signals. In the use process of the GPS satellite positioning system, in order to make GPS positioning more accurate, it is often necessary to select a GPS antenna radiator with a stronger ability to receive GPS satellite signals as a receiver of the GPS signals. When the posture of the electronic device 100 is fixed, one of the four GPS antenna radiators always exists, and the GPS antenna radiator has the weakest ability to receive GPS satellite signals. In order to select an antenna radiator with a stronger capability of receiving a GPS satellite signal, the candidate antenna radiator determination module 220 may select three candidate antenna radiators with a stronger capability of receiving a satellite signal from among the four GPS antenna radiators, and exclude the GPS antenna radiator with the weakest capability of receiving a satellite signal.

A signal strength obtaining module 230, configured to obtain a signal strength of at least one candidate antenna radiator;

and a target antenna radiator determining module 240, configured to determine a target antenna radiator according to the signal strength, where the target antenna radiator is used to receive a GPS satellite signal.

When the candidate antenna radiator determining module 220 determines three candidate antenna radiators, the signal strength obtaining module 230 may directly obtain the signal strength of one candidate antenna radiator from the three candidate antenna radiators, and when the signal strength meets the communication requirement, the target antenna radiator determining module 240 may directly use the candidate antenna radiator as a target antenna radiator, thereby greatly improving the antenna switching efficiency.

For the purpose of more accurate GPS positioning, the signal strength obtaining module 230 may further determine two or three when the candidate antenna radiators are determined, the signal strength obtaining module 230 controls the radio frequency switch 75 to alternately connect the candidate antenna radiators with the GPS chip 76 to form a plurality of GPS communication links, and by comparing the level values of different communication links, the signal strength of the candidate antenna radiators may be compared, and then the target antenna radiator determining module 240 may select the candidate antenna radiator with the largest signal strength as the target antenna radiator, so that the positioning of the electronic device 100 is more accurate.

The antenna radiator switching device 200 according to the embodiment of the present invention includes at least four antenna radiators, and each antenna radiator may be configured to receive a GPS signal. The antenna radiator switching device 200 provided in the embodiment of the present application first detects the current posture of the electronic device 100, and then determines three candidate antenna radiators from among at least four antenna radiators according to the current posture of the electronic device 100; then, obtaining the signal intensity of at least one candidate antenna radiator; and finally, determining a target antenna radiator according to the signal strength, and receiving the GPS signal through the target antenna radiator. According to the electronic device and the switching device, the target antenna radiator is determined from the three candidate antenna radiators, the electronic device 100 does not need to detect the signal strength of at least four GPS antenna radiators in turn, and the antenna switching efficiency is improved. Moreover, switching among at least four antenna radiators can adapt to different postures of the electronic device, and the electronic device 100 can be accurately positioned in any posture.

The candidate antenna radiator determining module 220 may be configured to perform the following steps:

determining two side edges positioned on the reference side edge and adjacent to the reference side edge as three candidate side edges;

and determining three candidate antenna radiators from the antenna radiators on the three candidate sides, wherein one candidate antenna radiator is arranged on each candidate side.

For example, when the electronic device 100 is in the vertical and forward posture, the horizontal height of the first side 101 is higher than the horizontal heights of the other three sides, and the first side 101 may be selected as the reference side. And, the third side 103 and the fourth side 104 located at two adjacent sides of the first side 101 may be selected as three candidate sides together with the first side 101. At this time, the patterns of the first, third and fourth

GPS antenna radiators

71, 73 and 74 on the three candidate sides may be matched with the GPS satellites, and the candidate antenna radiator determining module 220 may determine the first, third and fourth

GPS antenna radiators

71, 73 and 74 as the three candidate antenna radiators. Since the level of the second side 102 is less than the levels of the other three sides, the directional pattern of the second GPS antenna radiator 72 on the second side 102 does not match the GPS satellite, and the candidate antenna radiator determination module 220 may consider only using the three candidate antenna radiators and not the second GPS antenna radiator 72 for receiving GPS satellite signals.

When the electronic device 100 is in the vertical reverse posture, the horizontal height of the second side 102 is higher than the horizontal heights of the other three sides, and the second side 102 may be selected as a reference side. And, the third side 103 and the fourth side 104 located at two adjacent sides of the second side 102 may be selected as three candidate sides together with the second side 102. At this time, the patterns of the second, third and fourth

GPS antenna radiators

72, 73 and 74 on the three candidate sides may be matched with the GPS satellites, and the candidate antenna radiator determining module 220 may determine the second, third and fourth

GPS antenna radiators

72, 73 and 74 as the three candidate antenna radiators. Since the level of the first side 101 is less than the levels of the other three sides, the directional pattern of the first GPS antenna radiator 71 on the first side 101 does not match the GPS satellite, and the candidate antenna radiator determining module 220 may consider only using the three candidate antenna radiators and not considering using the first GPS antenna radiator 71 to receive GPS satellite signals.

When the posture of the electronic device 100 is a horizontal forward posture, the horizontal height of the third side 103 is higher than the horizontal heights of the other three sides, and the third side 103 may be selected as a reference side. And, the first side 101 and the second side 102 located at two adjacent sides of the third side 103 may be selected as three candidate sides together with the third side 103. At this time, the patterns of the third GPS antenna radiator 73, the first GPS antenna radiator 71 and the second GPS antenna radiator 72 on the three candidate sides 103 may be matched with the GPS satellites, and the candidate antenna radiator determining module 220 may determine the third GPS antenna radiator 73, the first GPS antenna radiator 71 and the second GPS antenna radiator 72 as the three candidate antenna radiators. Since the level of the fourth side 104 is less than the levels of the other three sides, the directional pattern of the fourth GPS antenna radiator 74 on the fourth side 104 does not match the GPS satellite, and the candidate antenna radiator determining module 220 may consider only using the three candidate antenna radiators and not using the fourth GPS antenna radiator 74 to receive GPS satellite signals.

When the electronic device 100 is in the landscape orientation, the level of the fourth side 104 is higher than the levels of the other three sides, and the fourth side 104 may be selected as the reference side. And, the first side 101 and the second side 102 located at two adjacent sides of the fourth side 104 may be selected as three candidate sides together with the fourth side 104. At this time, the patterns of the fourth GPS antenna radiator 74, the first GPS antenna radiator 71 and the second GPS antenna radiator 72 on the four candidate sides may be matched with the GPS satellites, and the candidate antenna radiator determining module 220 may determine the fourth GPS antenna radiator 74, the first GPS antenna radiator 71 and the second GPS antenna radiator 72 as the three candidate antenna radiators. Since the third side 103 has a lower level than the other three sides, the directional pattern of the third GPS antenna radiator 73 on the third side 103 does not match the GPS satellite, and the candidate antenna radiator determining module 220 may consider only using the three candidate antenna radiators and not the fourth GPS antenna radiator 74 for receiving GPS satellite signals.

It is to be understood that, when the number of antenna radiators on the three candidate sides is greater than three, the electronic device may select three radiators from the three candidate antenna radiators as the three candidate antenna radiators. Specifically, the electronic device may determine, according to the spatial parameter of each antenna radiator, the capability of the antenna radiator to receive the GPS signal, and select three antenna radiators with higher capability as candidate antenna radiators. Of course, the electronic device 100 may also select the candidate antenna radiator with reference to the surrounding environment of each antenna radiator.

After determining that the three GPS antenna radiators are located on the reference side of the electronic device 100 and the side adjacent to the reference side, the signal strength obtaining module 230 may directly use the three GPS antenna radiators as candidate antenna radiators, and the candidate antenna radiator determining module 220 may directly control the radio frequency switch 75 to switch to the corresponding candidate antenna radiators in turn, select the candidate antenna radiator with stronger signal strength as a target antenna radiator by comparing the level values of the three candidate antenna radiators, and use the target antenna radiator to receive GPS satellite signals.

The signal strength obtaining module 230 may directly obtain a first signal strength of the candidate antenna radiator located on the reference side;

for example, the signal strength obtaining module 230 may directly control the radio frequency switch 75 to electrically connect the candidate antenna radiator located on the reference side with the GPS chip 76 and form a communication link, obtain a first level value on the communication link, and reflect the first signal strength value by using the first level value.

Of course, the electronic device 100 may also gradually obtain the signal strength of the candidate antenna radiator. The signal strength acquisition module 230 may be further configured to perform the following steps:

judging whether the first signal intensity is greater than a preset signal intensity threshold value or not;

If the determination result is yes, the signal strength obtaining module 230 stops obtaining the signal strength of the candidate antenna radiator located on the adjacent side;

when the determination result is yes, it indicates that the candidate antenna radiator located on the reference side may meet the requirement of GPS positioning, and at this time, the candidate antenna radiator located on the reference side may be directly determined as the target antenna radiator without acquiring the signal strength of other candidate antenna radiators.

If the determination result is negative, the signal strength obtaining module 230 continues to obtain the signal strength of the candidate antenna radiator on at least one adjacent side.

If the result of the determination is negative, it indicates that the candidate antenna radiator located on the reference side cannot meet the requirement of GPS positioning, and in order to ensure accuracy of GPS positioning, the electronic device 100 needs to continuously obtain signal strengths of other candidate antenna radiators, and select an antenna radiator with a higher signal strength as a target antenna radiator.

For example, when the posture of the electronic device 100 is a vertical forward posture, the level of the first side 101 is higher than the levels of the other three sides, and the signal strength obtaining module 230 may control the radio frequency switch 75 to directly electrically connect the first GPS antenna radiator 71 located on the first side 101 and the GPS chip 76, so as to obtain the first signal strength of the first GPS antenna radiator 71. Then, judging whether the first signal intensity is greater than a preset signal intensity threshold value; if the determination result is yes, stopping acquiring the signal strength of the third GPS antenna radiator 73 and the fourth GPS antenna radiator 74 on the third side 103 and the fourth side 104; and directly using the first GPS antenna radiator 71 as a target antenna radiator, and receiving GPS satellite signals using the target antenna radiator. If the determination result is negative, the signal strength of at least one of the third GPS antenna radiator 73 and the fourth GPS antenna radiator 74 is continuously obtained.

When the posture of the electronic device 100 is a vertical reverse posture, the horizontal height of the second side 102 is higher than the horizontal heights of the other three sides, and the signal strength obtaining module 230 may control the radio frequency switch 75 to directly electrically connect the second GPS antenna radiator 72 located on the second side 102 with the GPS chip 76, so as to obtain the signal strength of the second GPS antenna radiator 72. Then, judging whether the first signal intensity is greater than a preset signal intensity threshold value; if the determination result is yes, stopping acquiring the signal strength of the third GPS antenna radiator 73 and the fourth GPS antenna radiator 74 on the third side 103 and the fourth side 104; and directly uses the second GPS antenna radiator 72 as a target antenna radiator and receives GPS satellite signals using the target antenna radiator. If the determination result is negative, the signal strength of at least one of the third GPS antenna radiator 73 and the fourth GPS antenna radiator 74 is continuously obtained.

When the posture of the signal strength acquiring module 230 is a horizontal forward posture, the horizontal height of the third side 103 is higher than the horizontal heights of the other three sides, and the electronic device 100 may control the radio frequency switch 75 to directly electrically connect the third GPS antenna radiator 73 located on the third side 103 with the GPS chip 76, so as to acquire the signal strength of the third GPS antenna radiator 73. Then, judging whether the first signal intensity is greater than a preset signal intensity threshold value; if the determination result is yes, stopping acquiring the signal strength of the first GPS antenna radiator 71 and the second GPS antenna radiator 72 on the first side 101 and the second side 102; and directly using the third GPS antenna radiator 73 as a target antenna radiator, and receiving a GPS satellite signal using the target antenna radiator. If the determination result is negative, the signal strength of at least one of the first GPS antenna radiator 71 and the second GPS antenna radiator 72 is continuously obtained.

When the posture of the signal strength acquiring module 230 is a horizontal reverse posture, the horizontal height of the fourth side 104 is higher than the horizontal heights of the other three sides, and the electronic device 100 may control the radio frequency switch 75 to directly electrically connect the fourth GPS antenna radiator 74 located on the fourth side 104 with the GPS chip 76, so as to acquire the signal strength of the fourth GPS antenna radiator 74. Then, judging whether the first signal intensity is greater than a preset signal intensity threshold value; if the determination result is yes, stopping acquiring the signal strength of the first GPS antenna radiator 71 and the second GPS antenna radiator 72 on the first side 101 and the second side 102; and directly uses the fourth GPS antenna radiator 74 as a target antenna radiator and receives GPS satellite signals using the target antenna radiator. If the determination result is negative, the signal strength of at least one of the first GPS antenna radiator 71 and the second GPS antenna radiator 72 is continuously obtained.

The antenna radiator switching device of the embodiment of the application directly obtains one signal strength of the antenna radiator, and when the candidate antenna radiator meets the communication requirement, the antenna radiator is directly taken as a target antenna radiator, and the signal strength obtaining module 230 does not need to detect the signal strength of three GPS antenna radiators in turn, so that the antenna switching efficiency is improved.

When the determination result is negative, in the step of continuously obtaining the signal strength of the candidate antenna radiators on at least one adjacent side, the signal strength obtaining module 230 may further determine whether to obtain the signal strength of one or two candidate antenna radiators through detection of a proximity sensor.

The step of the signal strength obtaining module 230 continuing to obtain the signal strength of the candidate antenna radiator on at least one adjacent side includes:

acquiring first position information of the first proximity sensor;

controlling the first proximity sensor to detect, and acquiring a first detection result of the proximity sensor;

and according to the first position information and the first detection result, continuously acquiring the signal strength of the candidate antenna radiator on one or two adjacent sides.

Also, the target antenna radiator determining module 240 may compare the second signal strength with the first signal strength of the candidate antenna radiator located on the reference side, and select the candidate antenna radiator with a higher signal strength as the target antenna radiator.

When the first location information is first positive location information and the first detection result is a first negative result, the first location information and the first negative location information together may indicate that no obstacle exists on the side where the first proximity sensor is located, and further, the candidate antenna radiator located on the side where the first proximity sensor is located is not blocked by an obstacle, and its surrounding environment is good, at this time, the signal strength obtaining module 230 needs to continue to obtain the signal strengths of the two candidate antenna radiators on two adjacent sides, and then, the target antenna radiator determining module 240 compares the strengths of the three candidate antenna radiators and selects the candidate antenna radiator with a greater signal strength as the target antenna radiator.

In addition to the above method, the signal strength obtaining module 230 may obtain the signal strength of at least one candidate antenna radiator by the following method.

The signal strength obtaining module 230 may be further configured to perform the following steps:

acquiring second position information of the second proximity sensor;

controlling the second proximity sensor to perform proximity detection and outputting a second detection result of the proximity sensor;

and acquiring the signal intensity of two or three candidate antenna radiators according to the second position information and the second detection result.

When the second location information is the second positive location information and the second detection result is the second positive result, the two together may indicate that there is an obstacle on the side where the second proximity sensor is located, and the obstacle may greatly affect the capability of the GPS antenna radiator located on the side to receive GPS satellite signals, so that the signal strength obtaining module 230 may directly obtain the signal strengths of the candidate antenna radiators on the remaining two candidate sides without considering the candidate antenna radiators on the adjacent side where the second proximity sensor is located. Then, the target antenna radiator determining module 240 may compare the signal strengths of the candidate antenna radiators on the remaining two candidate sides and select the candidate antenna radiator with the greater signal strength as the target antenna radiator.

When the second location information is second positive location information and the second detection result is a second negative result, the two may indicate that no obstacle exists on the side where the second proximity sensor is located, and further, the candidate antenna radiator located on the side where the second proximity sensor is located is not blocked by an obstacle, and its surrounding environment is good, at this time, the signal strength obtaining module 230 needs to continue to obtain the signal strengths of the three candidate antenna radiators on the three candidate sides, and then, the target antenna radiator determining module 240 compares the strengths of the three candidate antenna radiators and selects the candidate antenna radiator with a greater signal strength as the target antenna radiator.
