Please refer to FIG. 4 , which is a schematic diagram of a first indicator mark and a second indicator mark displayed on a display screen 500 in an embodiment of the present application. As shown in FIG. 4, a first indicator B1 and a second indicator B2 are displayed on the display screen 500, wherein the display parameters of the first indicator B1 and the second indicator B2 are different, and the display parameters Include at least one of color and pattern. Wherein, the distance between the first indicator mark B1 and the second indicator mark B2 is positively correlated with the angle deviation between the optimal direction of the antenna and the direction of the satellite, that is, the first indicator mark B1 and the second indicator mark The smaller the distance between the marks B2, the smaller the angle deviation between the optimal direction of the antenna and the direction of the satellite, and the larger the distance between the first indicator mark B1 and the second indicator mark B2, the greater the distance between the antenna optimal direction and the satellite direction. The greater the angular deviation of the optimal direction from the satellite direction.

Wherein, the positional relationship between the second indicator displayed on the display screen and the first indicator includes a distance and a relative direction.

Therefore, when the user performs the adjustment operation for adjusting the placement posture of the electronic device, he can observe the change of the positional relationship between the second indicator mark and the first indicator mark displayed on the display screen. The angle and direction for adjusting the placement attitude of the electronic device can be determined, so that the positions of the second indicator mark and the first indicator mark are close to each other, so that the optimal direction of the antenna of the satellite antenna is adjusted to be in line with the direction of the satellite. the same or approximately the same. In some embodiments, the user can know the smaller the distance between the first indicator mark and the second indicator mark through the operation manual or the new machine guide program, the smaller the angle deviation between the optimal direction of the antenna and the direction of the satellite.

Wherein, the position of the first indication mark at least includes the position where the optimal direction of the antenna is mapped on the display screen, and the second indication mark is the position where the satellite direction is mapped on the display screen. As mentioned above, generally speaking, after the electronic equipment is manufactured, the position of the satellite antenna on the electronic equipment is fixed, and the optimal direction of the antenna of the satellite antenna is also fixed relative to the electronic equipment, That is, it remains fixed relative to the display screen of the electronic device. In this application, no matter how the electronic device is placed, the first display displayed on the display screen is controlled according to the optimal direction of the antenna. The position of an indicator mark on the display screen is fixed. Since the second indicator is the position where the satellite direction is mapped on the display screen, when the posture of the electronic device changes, the angle between the plane of the display screen and the satellite direction will change. Therefore, the position of the second indication mark on the display screen changes as the placement posture of the electronic device changes. As mentioned above, since the pointing direction of the satellite antenna, that is, the optimal direction of the antenna of the satellite antenna, remains fixed with the electronic device, therefore, when the placement attitude of the electronic device changes, the satellite antenna The pointing direction also changes following the change of the placement posture of the electronic device.

Please also refer to FIG. 8 , which is a schematic diagram of an electronic device coordinate system when the electronic device is in a side view state in an embodiment of the present application. In some embodiments, the coordinate system of the electronic device specifically takes the center of the display screen 500 as the coordinate origin o, wherein the direction perpendicular to the display screen 500 and pointing to the viewing side of the display screen 500 is Z The positive direction of the axis, correspondingly, the direction perpendicular to the display screen 500 and pointing to the back surface F1 of the electronic device 1000 is the negative direction of the Z axis. Wherein, the determining the first target position of the antenna direction unit vector mapped on the display screen 500 according to the antenna coordinate position includes: obtaining a preset position located on the positive half axis of the Z axis of the electronic device coordinate system The coordinate position of the observation point of the observation point P1, the observation point P1 is separated from the coordinate origin o by a preset distance, the projection of the observation point P1 on the display screen 500 and the display screen as the coordinate origin o The center coincides; according to the coordinate position of the observation point and the coordinate position of the antenna, the first intersection coordinate position of the connection line between the observation point P1 and the antenna coordinate position point A1 and the intersection point of the display screen 500 is calculated, and the display The coordinate position of the first intersection point on the screen 500 is used as the first target position, wherein the antenna coordinate position point A1 is a point corresponding to the antenna coordinate position, and the Z-axis coordinate in the antenna coordinate position is negative.

Wherein, as shown in FIG. 8 , the aforesaid electronic device coordinate system takes the center of the display screen 500 as the coordinate origin o, the direction perpendicular to the display screen 500 as the Z axis, and the direction parallel to the display screen 500 as the Z axis. The short side direction of the screen 500 is the X axis, and the long side direction parallel to the display screen 500 is the Y axis. The display screen 500 specifically refers to the screen surface of the display screen 500, that is, the outermost surface of the screen , the plane where the display screen 500 is located in this application also refers to the plane where the screen of the display screen 500 is located.

Usually, the display screen 500 of the electronic device will block the radiation of the antenna. Therefore, usually, the radiation direction of the antenna is designed to face the back of the electronic device and form a certain angle with the back. Therefore, the When the coordinate system of the electronic equipment is perpendicular to the display screen and the direction pointing to the viewing side of the display screen is the positive direction of the Z-axis, the antenna unit vector of the best antenna direction of the satellite antenna of the present application points to the negative direction of the Z-axis , therefore, the Z-axis coordinate in the antenna coordinate position is negative.

In some embodiments, the coordinate position of the first intersection point of the intersection of the line connecting the observation point P1 and the antenna coordinate position point A1 and the display screen 500 is calculated according to the coordinate position of the observation point and the coordinate position of the antenna, May include:

According to the formula X1=L*x0/(L-z0) and y1=L*y0/(L-z0), the X-axis coordinate and the Y-axis coordinate in the coordinate position of the first intersection point are calculated to obtain the described The first intersection coordinate position (x1, y1, z1); wherein, the x1 is the X-axis coordinate in the first intersection coordinate position, and the y1 is the Y-axis coordinate in the first intersection coordinate position, so The z1 is the z-axis coordinate in the coordinate position of the first intersection point, since the intersection point is located on the display screen, z1=0, the L is the Z-axis coordinate of the observation point, and the x0 is the The X-axis coordinate of the antenna coordinate position, the y0 is the Y-axis coordinate of the antenna coordinate position, and the z0 is the Z-axis coordinate of the antenna coordinate position.

Wherein, as shown in Figure 8, the intersection point of the connection line between the observation point P1 and the antenna coordinate position point A1 and the display screen 500 is B1, and the ratios of the sides of similar triangles are equal to draw: x1/x0=y1 /y0=(L-z1)/(L-z0), where, since z1 is 0, it can be further obtained that x1/x0=y1/y0=L/(L-z0), thus, the above can be obtained Two formulas X1=L*x0/(L-z0) and y1=L*y0/(L-z0).

Wherein, Fig. 8 schematically shows a schematic diagram of a similar triangle formed by the projection of the antenna coordinate position point A1 and the intersection point B1 on the YZ plane. According to Fig. 8, it can be drawn that the projection point of the antenna coordinate position point A1 on the YZ plane is the same as The right triangle formed by the line connecting the observation point P1 and the Z axis, and the line connecting the projection point of the intersection point B1 on the YZ plane and the observation point P1 and another right triangle formed by the Z axis are similar triangles, so it can be concluded that y1 /y0=(L-z1)/(L-z0). Correspondingly, by forming a similar triangle with the projection of the antenna coordinate position point A1 and the intersection point B1 on the XZ plane, it can be obtained that x1/x0=(L-z1)/(L-z0), therefore, it can be obtained that x1/ x0=y1/y0=(L-z1)/(L-z0).

Wherein, if the observation point P1 is not introduced, then in fact, the direction of the line connecting the antenna coordinate position point A1 and the coordinate origin o is more the same as the antenna direction unit vector, therefore, the first indicator mark will be located at The coordinate origin o, and as can be known later, when the satellite direction is mapped onto the display screen, the same problem will also exist, and the second indicator marks will also be located at the coordinate origin o. Therefore, by introducing the observation point P1, the position of the first indicator mark on the display screen may not be located in the center of the display screen as much as possible, so as to avoid the difference between the first indicator mark and the second indicator mark. The marker coincides with the center of the display screen in the event that the antenna optimum direction of the satellite dish is not aligned with the satellite direction.

Wherein, as shown in FIG. 7 , in the coordinate system of the electronic device, when the display screen 500 is facing the user, the direction parallel to the short side of the display screen and pointing to the right is the positive direction of the X-axis. , the direction parallel to the long side direction of the display screen and pointing upward, that is, the direction parallel to the long side direction of the display screen and pointing to the top of the electronic device 1000 is the positive direction of the Y axis.

Since the placement posture of the electronic device is different, the plane where the display screen is located is different. Therefore, the coordinate system of the electronic device The directions of the X-axis, Y-axis and Z-axis in are different according to the placement attitude of the electronic device.

Please also refer to FIG. 11 , which is another schematic diagram of an electronic device coordinate system when the electronic device is in a side view state in an embodiment of the present application. In some embodiments, similarly, the coordinate system of the electronic device also takes the center of the display screen 500 as the coordinate origin o, wherein, the The direction is the positive direction of the Z axis, and correspondingly, the direction perpendicular to the display screen 500 and pointing to the back surface F1 of the electronic device 1000 is the negative direction of the Z axis. Wherein, the determining the second target position of the satellite direction unit vector mapped on the display screen according to the satellite coordinate position includes: obtaining a preset observation on the positive half axis of the Z axis of the electronic equipment coordinate system The coordinate position of the observation point of point P1, the observation point is separated from the coordinate origin by a preset distance, and the projection of the observation point P1 on the display screen 500 coincides with the center of the display screen as the coordinate origin o; According to the coordinate position of the observation point and the coordinate position of the satellite, the second intersection coordinate position of the connection line between the observation point P1 and the satellite coordinate position point A2 and the intersection point B2 of the display screen is calculated, and the second intersection point coordinate position on the display screen is displayed. The intersection point coordinate position is used as the second target position, wherein the Z-axis coordinate in the satellite coordinate position is negative, and wherein the satellite coordinate position point is a point corresponding to the satellite coordinate position.

Usually, in the process of using satellite communication, the position of the satellite is generally located on the back of the electronic device, therefore, the coordinate system of the electronic device is perpendicular to the display screen and the direction pointing to the viewing side of the display screen is the Z axis In the positive direction, the satellite direction unit vector of the present application also points to the negative direction of the Z-axis, therefore, the Z-axis coordinate in the satellite coordinate position is negative.

In some embodiments, the calculation according to the coordinate position of the observation point and the satellite coordinate position to obtain the second intersection coordinate position of the line connecting the observation point P1 and the satellite coordinate position point A2 and the intersection B2 of the display screen includes:

According to the formula x3=L*x4/(L-z4) and y3=L*y4/(L-z4), the X-axis coordinate and the Y-axis coordinate in the coordinate position of the second intersection point are calculated to obtain the described The second intersection point coordinate position (x3, y3, z3); wherein, the x3 is the X-axis coordinate in the second intersection point coordinate position, and the y3 is the Y-axis coordinate in the second intersection point coordinate position, so The z3 is the Z-axis coordinate in the second intersection point coordinate position, the z3=0, the L is the Z-axis coordinate of the observation point, and the x4 is the X-axis coordinate in the satellite coordinate position, That is, the X-axis coordinate of the satellite coordinate position point A2, the y4 is the Y-axis coordinate in the satellite coordinate position, that is, the Y-axis coordinate of the satellite coordinate position point A2, and the z4 is the satellite The Z-axis coordinate in the coordinate position, that is, the Z-axis coordinate of the satellite coordinate position point A2.

Wherein, as shown in Figure 11, the intersection point of the connection line between the observation point P1 and the satellite coordinate position point A2 and the display screen 500 is B2, and the ratios of the sides of similar triangles are equal to draw: x3/x4=y3 /y4=(L-z3)/(L-z4), where, since z3 is 0, it can be further obtained that x3/x4=y3/y4=L/(L-z4), thus, the above can be obtained Two formulas x3=L*x4/(L-z4) and y3=L*y4/(L-z4).

Wherein, shown in Fig. 11 is the schematic diagram that the projection of the satellite coordinate position point A2 and the intersection point B2 on the YZ plane forms a similar triangle. According to Fig. 1, it can be drawn that the projection point of the satellite coordinate position point A2 on the YZ plane is the same as The right triangle formed by the line connecting the observation point P1 and the Z axis, and the other right triangle formed by the line connecting the projection point of the intersection point B2 on the YZ plane and the observation point P1 and the Z axis are similar triangles, so it can be concluded that y3 /y4=(L-z3)/(L-z4). Correspondingly, by forming a similar triangle with the projection of the satellite coordinate position point A2 and the intersection point B2 on the XZ plane, it can be obtained that x3/x4=(L-z3)/(L-z4), therefore, it can be obtained that x1/ x0=y1/y0=(L-z1)/(L-z0).

Therefore, through the above method steps, the second target position displayed on the display screen by the second indication mark in the current placement posture of the electronic device can be determined. As mentioned above, since the second target position mapped on the display screen by the satellite direction unit vector is determined according to the conversion of the satellite direction unit vector to the satellite coordinate position in the electronic device coordinate system, and according to In the aforementioned calculation method, the satellite coordinate position changes according to the change of the placement attitude of the electronic device.

Wherein, the value of the aforementioned Z-axis coordinate L of the observation point may be a value in d/2-3d, wherein the "d" is the length of the long side of the display screen of the electronic device.

Wherein, if the observation point P1 is not introduced, then in fact, the direction of the line connecting the antenna coordinate position point A1 and the coordinate origin o is more the same as the antenna direction unit vector, and the satellite coordinate position point A2 and the coordinate origin o The direction of the connecting line is also the same as the satellite direction unit vector. Therefore, both the first indicator mark and the second indicator mark are located at the coordinate origin o. In the present application, by introducing the observation point P1, the first indicator mark and the second indicator mark may not be located in the center of the display screen as much as possible, and the first indicator mark and the second indicator mark may be avoided. The indication mark coincides with the center of the display screen when the optimal direction of the antenna of the satellite antenna is not aligned with the direction of the satellite, and due to the first target position of the first indication mark and the second In the process of determining the second target position of the indicator mark, the observation point P1 is introduced, so it can still accurately reflect the optimal direction of the antenna and the deviation of the satellite antenna.

Wherein, the aforesaid controlling the corresponding movement of the second indication mark in response to the adjustment operation of the placement posture of the electronic device may include: re-determining the current position of the electronic device 1000 in response to the adjustment operation of the placement posture of the electronic device. In the placement posture, the second indicator mark is displayed on the display screen at the second target position, and the second indicator mark is controlled to be displayed at the re-determined second target position.

Wherein, in the operation of adjusting the placement posture of the electronic device, the electronic device can be re-determined at intervals of the current placement posture of the electronic device, and the second indication mark displayed on the display screen the second target position, and control the second indication mark to be displayed at the re-determined second target position. Wherein, the preset time may be a short distance such as 0.2 seconds, so that due to effects such as visual persistence, the user sees that the second indication mark moves on the display screen more smoothly.

Wherein, in the re-determining the second target position displayed on the display screen by the second indication mark under the current placement posture of the electronic device 1000, please refer to the aforementioned determination of the second target position for details. way, which will not be repeated here.

Please also refer to FIG. 12 , which is a schematic diagram of the first indicator mark and the second indicator mark displayed on the display screen 500 in some embodiments of the present application. As shown in Figure 12, the first indicator mark B1 includes a central point B11 and an annular area B12 surrounding the central point B11, the central point B11 is used to represent the optimal direction of the antenna, and the annular area B12 is used for to characterize the next-best orientation of the antenna. Wherein, the method further includes: during the process of controlling the corresponding movement of the second indicator mark B2 in response to the adjustment operation of the placement posture of the electronic device 1000 , when the second indicator mark B2 moves to the When the first indication mark B1 is within the ring-shaped area B12, the control generates a first prompt signal.

Wherein, since the annular area B12 is used to characterize the second-best direction of the antenna, it means that when the satellite direction is approximately the same as the second-best direction of the antenna, the antenna gain of the satellite antenna 400 is greater than or equal to a preset threshold, therefore, when the second When the second indicator B2 moves into the ring-shaped area B12 of the first indicator B1, the user is reminded by generating the first prompt signal, and it is no longer necessary to adjust the placement posture of the electronic device 1000, and timely reminders can be effectively carried out , and can reduce the adjustment time. Wherein, the preset threshold is the threshold satisfying better satellite antenna communication quality, which is a value determined in advance through experiments or the like.

In some other embodiments, the method also includes: in response to the adjustment operation on the placement posture of the electronic device 1000 , during the process of adjusting the placement posture of the electronic device, calculating the Antenna gain, when the antenna gain of the satellite antenna 200 is greater than or equal to a preset threshold, control to generate a first prompt signal. Wherein, how to calculate the antenna gain is not the protection focus of this application, and the antenna gain of the satellite antenna 200 can be calculated through some existing antenna gain algorithms.

That is, since the annular area B12 is used to characterize the second-best direction of the antenna, indicating that when the satellite direction is approximately the same as the second-best direction of the antenna, the antenna gain of the satellite antenna 400 is greater than or equal to a preset threshold value, therefore, the satellite antenna The antenna gain of 400 is greater than or equal to the preset threshold, which corresponds to the movement of the second indicator mark B2 into the ring-shaped area B12 of the first indicator mark B1. Therefore, in some other embodiments, the antenna gain of the satellite antenna 200 may also be directly calculated, and when the antenna gain of the satellite antenna 200 is greater than or equal to a preset threshold, control generates a first prompt signal.

In some embodiments, the first prompt signal may be a voice prompt signal, such as outputting voice content such as "the current posture has reached a better state". In some embodiments, the first prompt signal may be a vibration prompt signal, which reminds the user through vibration. In some embodiments, the first prompt signal can also be used to control the display parameters and/or display methods of the annular area B12 to change, the display parameters can include one of color and pattern, and the display method May include blinking displays and the like. Therefore, the user is prompted that the current antenna gain of the satellite antenna 400 is greater than or equal to the preset threshold.

In some embodiments, the method further includes: when the second indicator mark moves to the center point of the first indicator mark, controlling to generate a second prompt signal. Wherein, the second prompt signal may also be a voice prompt signal, for example, outputting voice content such as "the current posture has reached the best state". The second prompt signal may also be a vibration prompt signal, and the vibration intensity is greater than that of the first prompt signal. In some embodiments, the second prompt signal can also be used to control the display parameters and/or display methods of the central point B11 to change, the display parameters can include one of color and pattern, and the display method May include blinking displays and the like. Therefore, the user is prompted that under the current placement attitude, the optimal direction of the antenna is already the same as the direction of the satellite, that is, the current antenna gain of the satellite antenna 400 is already optimal.

In some embodiments, the display parameters of the annular area B12 and the central point B11 are different, and the display parameters include at least one of color and pattern, so that the annular area B12 and the central point can be effectively distinguished B11, which allows the user to intuitively distinguish whether the second indicator B2 has moved to the ring-shaped area B12 or the center point B11.

Wherein, the position and size of the ring-shaped area B12 can be determined according to a set of positions mapped on the display screen 500 from the second-best direction of the antenna. Wherein, the direction that deviates from the optimal direction of the antenna within a certain angle is the sub-optimal direction of the antenna, therefore, the annular area B12 is mapped on the display screen 500 .

Wherein, as shown in FIG. 12 , the second indicator B2 may be a satellite pattern, so as to show the direction of the satellite more intuitively.

Please refer to FIG. 13 , which is a schematic diagram of the movement of the second indicator mark B2 following the change of the placement posture of the electronic device 1000 in an embodiment of the present application.

As shown in FIG. 13 , taking the electronic device 1000 upright as an example, that is, the display screen 500 of the electronic device 1000 faces the user, with the top facing up and the bottom facing down. When the electronic device 1000 rotates clockwise around the X-axis, the second indication mark B2 moves upward in the display screen 500 under the viewing angle shown in FIG. When turning, the second indication mark B2 moves downward in the display screen 500 under the viewing angle shown in FIG. 13 . When the electronic device 1000 rotates clockwise around the Y axis, the second indicator B2 moves leftward in the display screen 500 from the viewing angle shown in FIG. 13 ; When the hour hand rotates, the second indicator B2 moves to the right in the display screen 500 under the viewing angle shown in FIG. 13 . When the electronic device 1000 rotates counterclockwise around the Z axis, the second indicator mark B2 moves clockwise in the display screen 500 under the viewing angle shown in FIG. When the clock hand turns, the second indicator mark B2 moves counterclockwise in the display screen 500 under the viewing angle shown in FIG. 13 .

Wherein, the above clockwise and counterclockwise rotations are the rotation states viewed from the positive half axis of the corresponding coordinate axis.

Please refer to FIG. 14 , which is a simulation schematic diagram of the second indicator mark B2 gradually aligning to the first indicator mark B1 in an embodiment of the present application. As shown in (a) of Figure 14, in the initial state, the second indicator mark B2 is located above the left upper side of the first indicator mark B1, thus, the second indicator mark B2 needs to move to the right, Downward and/or clockwise movement, as shown in (b)-(e) shown in Figure 14, by rotating the electronic device 1000 counterclockwise around the Z axis Rotate counterclockwise, so that the second indicator mark B2 can gradually approach the first indicator mark B1 until it reaches the second indicator mark B2 and the first indicator mark B1 as shown in (e) in FIG. 14 . A state indicating that the marks B1 overlap or are close to overlap.
