However, it should be understood that the method for guiding and adjusting the pointing direction of the satellite antenna of the present application is not limited to the electronic devices shown in fig. 1-2.
Referring to fig. 3, a flowchart of a method for guiding and adjusting a pointing direction of a satellite antenna according to an embodiment of the present application is shown, where the method is applied to an electronic device, and the electronic device includes the satellite antenna and a display screen, as shown in fig. 3, the method includes:

The optimal direction of the antenna in the present application is a satellite antenna pointing direction, and the guiding and adjusting of the satellite antenna pointing direction also refers to guiding a user to adjust a placement posture of the electronic device so as to adjust the optimal direction of the antenna.
Please refer to fig. 4, which is a schematic diagram of a first indicator and a second indicator displayed on a display screen 500 according to an embodiment of the present application. As shown in fig. 4, a first indicator mark B1 and a second indicator mark B2 are displayed on the display screen 500, wherein the first indicator mark B1 and the second indicator mark B2 have different display parameters, and the display parameters at least include one of color and pattern. The distance between the first indicator mark B1 and the second indicator mark B2 is positively correlated with the angular deviation between the antenna optimum direction and the satellite direction, that is, the smaller the distance between the first indicator mark B1 and the second indicator mark B2 is, the smaller the angular deviation between the antenna optimum direction and the satellite direction is, and the larger the distance between the first indicator mark B1 and the second indicator mark B2 is, the larger the angular deviation between the antenna optimum direction and the satellite direction is. Wherein fig. 4 is a view for example only, the first indicator B1 and the second indicator B2 are not limited to the colors or patterns shown in fig. 4.
In some embodiments, the method further comprises: and controlling the corresponding change of the position relation between the second indication mark and the first indication mark displayed on the display screen in response to the adjustment operation of the placing posture of the electronic equipment, so as to prompt the change of the angle deviation of the optimal antenna direction and the satellite direction, and guiding to adjust the pointing direction of the satellite antenna by adjusting the placing posture of the electronic equipment 1000. Wherein the positional relationship between the first indicator and the second indicator displayed on the display screen includes a distance and a relative direction.
Thus, when performing an adjustment operation for adjusting the placement attitude of the electronic device, the user can determine the angle and direction at which the placement attitude of the electronic device is adjusted by observing a change in the positional relationship between the second indicator mark and the first indicator mark displayed on the display screen, so that the positions of the second indicator mark and the first indicator mark are close to each other, thereby achieving adjustment of the antenna optimum direction of the satellite antenna to be the same as or substantially the same as the satellite direction. In some embodiments, the user can know that the smaller the distance between the first indicator mark and the second indicator mark is, the smaller the angular deviation between the optimal direction of the antenna and the satellite direction is. The user can hold the electronic equipment and adjust the placing posture of the electronic equipment by rotating the electronic equipment and the like.
In some embodiments, the fixing of the position of the first indicator on the display screen, the changing of the position of the second indicator on the display screen following the changing of the placement posture of the electronic device, the changing of the pointing direction of the satellite antenna 400 following the changing of the placement posture of the electronic device, and the controlling of the corresponding change of the position relationship between the second indicator displayed on the display screen and the first indicator in response to the adjustment operation of the placement posture of the electronic device may include: and controlling the second indicating mark to correspondingly move in response to the adjustment operation of the placing posture of the electronic equipment, so that the position relation between the second indicating mark and the first indicating mark displayed on the display screen is correspondingly changed.
Wherein the position of the first indicator mark at least comprises the position of the optimal direction of the antenna mapped on the display screen, and the second indicator mark is the position of the satellite direction mapped on the display screen. As mentioned above, generally speaking, after the electronic device is manufactured, the position of the satellite antenna on the electronic device is fixed, and the antenna optimal direction of the satellite antenna is also fixed relative to the electronic device, i.e. fixed relative to the display screen of the electronic device. And because the second indication mark is the position of the satellite direction mapped on the display screen, when the placing posture of the electronic equipment is changed, the angle between the plane of the display screen and the satellite direction is changed, and therefore, the position of the second indication mark on the display screen is changed along with the change of the placing posture of the electronic equipment. As described above, since the pointing direction of the satellite antenna, that is, the optimal direction of the antenna of the satellite antenna, is fixed with the electronic device, when the placement attitude of the electronic device changes, the pointing direction of the satellite antenna also changes along with the change in the placement attitude of the electronic device.
Therefore, after the second indication mark is controlled to correspondingly move in response to the adjustment operation of the placing posture of the electronic equipment, the position relation between the second indication mark and the first indication mark is changed, and a user can be intuitively and effectively guided to adjust the placing posture of the electronic equipment to enable the second indication mark and the first indication mark to be as close as possible, so that the pointing direction of the satellite antenna is adjusted to be pointed or approximately pointed to the position of a satellite, namely the optimal direction of the satellite antenna is adjusted to be the same or approximately the same as the direction of the satellite, and the antenna gain is improved.
Referring to fig. 5 and fig. 6 together, fig. 5 is a schematic view illustrating the electronic device 1000 in a first placement posture according to an embodiment of the present disclosure, and fig. 6 is a schematic view illustrating adjusting the placement posture of the electronic device to a second placement posture according to an embodiment of the present disclosure.
The optimal direction of the antenna of the satellite antenna is fixed and unchanged relative to the electronic device 1000, and therefore changes with the change of the placement attitude of the electronic device 1000, and the satellite direction refers to the direction of the satellite relative to the electronic device 1000, and since the period of the satellite rotating around the earth is often long, the satellite direction of the satellite relative to the electronic device 1000 can also be regarded as unchanged within a certain time. Therefore, as shown in fig. 5, when the satellite antenna is in the first placement posture, the deviation angle between the antenna optimal direction of the satellite antenna and the satellite direction is large.
As shown in fig. 5 and 6, when the user holds the electronic device 1000, the user faces the display screen 500 of the electronic device 1000, so that the first indicator mark and the second indicator mark displayed on the display screen 500 can be viewed. As shown in fig. 6, the user may adjust the placement posture of the electronic device to adjust the optimal antenna direction of the satellite antenna according to the directions of the first indicator mark and the second indicator mark, as shown in fig. 6, when the electronic device is in the second placement posture, the optimal antenna direction of the satellite antenna is the same or substantially the same as the satellite direction.
Therefore, in the present application, by displaying the first indication mark and the second indication mark for guidance, a user can be effectively guided to adjust the placement posture of the electronic device so that the optimal direction of the antenna of the satellite antenna is the same or substantially the same as the direction of the satellite.

Fig. 8 is a schematic view of a coordinate system of an electronic device in a side view state according to an embodiment of the present application. In some embodiments, the electronic device coordinate system further uses 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 a positive Z-axis direction, and correspondingly, the direction perpendicular to the display screen 500 and pointing to the back F1 of the electronic device 1000 is a negative Z-axis direction. 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: acquiring a preset observation point coordinate position of an observation point P1 located on a Z-axis positive half shaft of an electronic equipment coordinate system, wherein the observation point P1 is spaced from the origin of coordinates o by a preset distance, and the projection of the observation point P1 on the display screen 500 is overlapped with the center of the display screen serving as the origin of coordinates o; and calculating a first intersection point coordinate position of an intersection point of a connecting line of an observation point P1 and an antenna coordinate position point A1 and the display screen 500 according to the observation point coordinate position and the antenna coordinate position, and taking the first intersection point coordinate position on the display screen 500 as the first target position, wherein the antenna coordinate position point A1 is a point corresponding to the antenna coordinate position, and a Z-axis coordinate in the antenna coordinate position is negative.
As shown in fig. 8, in the foregoing coordinate system of the electronic device, the center of the display screen 500 is used as a coordinate origin o, a direction perpendicular to the display screen 500 is used as a Z axis, a direction parallel to a short side of the display screen 500 is used as an X axis, and a direction parallel to a long side of the display screen 500 is used as a Y axis, where the display screen 500 specifically refers to a screen of the display screen 500, that is, a plane on an outermost side of the display screen, a plane on which the display screen 500 is located in this application, and also refers to a plane on which a screen of the display screen 500 is located.
Under the general condition, electronic equipment's display screen 500 can cause the sheltering from to the radiation of antenna, therefore, under the general condition, the radiation direction of antenna all design for the back towards electronic equipment and with the back is certain angle, consequently, electronic equipment coordinate system perpendicular to the display screen just points to when the direction of the viewing side of display screen is Z axle positive direction, the antenna unit vector of the best direction of satellite antenna's of this application then is Z axle negative direction, consequently, Z axle coordinate in the antenna coordinate position is the negative.
In some embodiments, the calculating a first intersection coordinate position of an intersection point of a connection line between observation point P1 and antenna coordinate position point a1 and the display screen 500 according to the observation point coordinate position and the antenna coordinate position may include:
calculating the X-axis coordinate and the Y-axis coordinate in the first intersection coordinate position according to the formulas X1= L X0/(L-z0) and Y1= L Y0/(L-z0), thereby obtaining the first intersection coordinate position (X1, Y1, z 1); wherein X1 is an X-axis coordinate in the first intersection coordinate position, Y1 is a Y-axis coordinate in the first intersection coordinate position, Y1 is a Z-axis coordinate in the first intersection coordinate position, Z1=0 since the intersection is located on the display screen, L is a Z-axis coordinate of the observation point, X0 is an X-axis coordinate of the antenna coordinate position, Y0 is a Y-axis coordinate of the antenna coordinate position, and Z0 is a Z-axis coordinate of the antenna coordinate position.
As shown in fig. 8, an intersection point of a connection line between the observation point P1 and the antenna coordinate position point a1 and the display screen 500 is B1, and the ratio of each side of the similar triangle is equal to obtain: X1/X0= y1/y0= (L-z1)/(L-z0), wherein since z1 is 0, it is possible to further derive X1/X0= y1/y0= L/(L-z0), and thus, the above two formulae X1= L × 0/(L-z0) and y1= L × y0/(L-z0) can be obtained.
Fig. 8 schematically illustrates a right triangle formed by the projection of the antenna coordinate position point a1 and the intersection point B1 on the YZ plane, and it can be found from fig. 8 that a right triangle formed by the connection line of the projection point of the antenna coordinate position point a1 on the YZ plane and the observation point P1 and the Z axis, and another right triangle formed by the connection line of the projection point of the intersection point B1 on the YZ plane and the observation point P1 and the Z axis are similar triangles, so that y1/y0= (L-Z1)/(L-Z0) can be found. Accordingly, by forming a similar triangle by the projection of the antenna coordinate position point a1 and the intersection point B1 on the XZ plane, x1/x0= (L-z1)/(L-z0) can be obtained, and thus, x1/x0= y1/y0= (L-z1)/(L-z0) can be obtained.
If the observation point P1 is not introduced, the direction of the connection line between the antenna coordinate position point a1 and the origin of coordinates o is actually the same as the unit vector of the antenna direction, which results in the first indicator mark being located at the origin of coordinates o. Thus, by introducing the observation point P1, the position of the first indicator mark on the display screen can be kept as small as possible from being located at the center of the display screen, and the first indicator mark and the second indicator mark can be prevented from being overlapped at the center of the display screen in the case where the optimal antenna direction of the satellite antenna is not aligned with the satellite direction.

Therefore, the satellite coordinate position of the satellite direction unit vector of the electronic equipment in the electronic equipment coordinate system can be accurately obtained through the method.
Fig. 11 is another schematic view of a coordinate system of an electronic device in a side view state according to an embodiment of the present application. In some embodiments, the electronic device coordinate system further uses 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 a positive Z-axis direction, and correspondingly, the direction perpendicular to the display screen 500 and pointing to the back F1 of the electronic device 1000 is a negative Z-axis direction. Wherein the determining a second target position of the unit vector of satellite direction mapped on the display screen according to the coordinate position of the satellite comprises: acquiring a preset observation point coordinate position of an observation point P1 located on a Z-axis positive half shaft of an electronic device coordinate system, wherein the observation point is separated from the origin of coordinates by a preset distance, and the projection of the observation point P1 on the display screen 500 is overlapped with the center of the display screen serving as the origin of coordinates o; and calculating a second intersection point coordinate position of a connecting line of an observation point P1 and a satellite coordinate position point A2 and an intersection point B2 of the display screen according to the observation point coordinate position and the satellite coordinate position, and taking the second intersection point coordinate position on the display screen as the second target position, wherein the Z-axis coordinate in the satellite coordinate position is negative, and the satellite coordinate position point is a point corresponding to the satellite coordinate position.
In general, in the process of using satellite communication, the position of a satellite is generally located on the back of an electronic device, and therefore, when 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 positive direction of the Z axis, the unit vector of the satellite direction of the application points to the negative direction of the Z axis, and therefore, the coordinate of the Z axis in the coordinate position of the satellite is negative.
In some embodiments, the calculating a second intersection coordinate position of the intersection B2 of the connection line between the observation point P1 and the satellite coordinate position point a2 and the display screen according to the observation point coordinate position and the satellite coordinate position includes:
calculating the X-axis coordinate and the Y-axis coordinate in the second intersection coordinate position according to formulas X3= L X4/(L-z4) and Y3= L Y4/(L-z4), so as to obtain the second intersection coordinate position (X3, Y3, z 3); wherein X3 is the X-axis coordinate in the second point coordinate position, Y3 is the Y-axis coordinate in the second point coordinate position, Z3 is the Z-axis coordinate in the second point coordinate position, Z3=0 is the Z-axis coordinate of the observation point, X4 is the X-axis coordinate in the satellite coordinate position, i.e., the X-axis coordinate of the satellite coordinate position point a2, Y4 is the Y-axis coordinate in the satellite coordinate position, i.e., the Y-axis coordinate of the satellite coordinate position point a2, and Z4 is the Z-axis coordinate in the satellite coordinate position, i.e., the Z-axis coordinate of the satellite coordinate position point a 2.
As shown in fig. 11, an intersection point of a connection line between the observation point P1 and the satellite coordinate position point a2 and the display screen 500 is B2, and the ratio of each side of the similar triangle is equal to obtain: x3/x4= y3/y4= (L-z3)/(L-z4), wherein since z3 is 0, it is possible to further derive x3/x4= y3/y4= L/(L-z4), and thus, the above two formulae x3= L × 4/(L-z4) and y3= L × y4/(L-z4) can be obtained.
Fig. 11 schematically illustrates a similar triangle formed by the projection of the satellite coordinate position point a2 and the intersection point B2 on the YZ plane, and it can be found from fig. 1 that a right triangle formed by the connecting line of the projection point of the satellite coordinate position point a2 on the YZ plane and the observation point P1 and the Z axis and another right triangle formed by the connecting line of 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 that y3/y4= (L-Z3)/(L-Z4) can be obtained. Accordingly, by forming a similar triangle by the projection of the satellite coordinate position point a2 and the intersection point B2 on the XZ plane, x3/x4= (L-z3)/(L-z4) and therefore, x1/x0= y1/y0= (L-z1)/(L-z0) can be obtained.
Therefore, through the steps of the method, the second target position displayed on the display screen by the second indicating mark in the current placing posture of the electronic equipment can be determined. As mentioned above, the second target position mapped on the display screen by the satellite direction unit vector is determined according to the satellite coordinate position converted into the coordinate system of the electronic device, and according to the above calculation method, the satellite coordinate position is changed according to the change of the placing posture of the electronic device.
The value of the Z-axis coordinate L of the observation point may be a value in d/2-3d, where "d" is a length of a long side of a display screen of the electronic device.
If the observation point P1 is not introduced, the direction of the connection line between the antenna coordinate position point a1 and the origin o is substantially the same as the antenna direction unit vector, and the direction of the connection line between the satellite coordinate position point a2 and the origin o is substantially the same as the satellite direction unit vector. This results in the first index mark and the second index mark both being located at the origin of coordinates o. In the present application, by introducing the observation point P1, the first indication mark and the second indication mark may be located as far as possible from the center of the display screen, and the observation point P1 may be introduced in the determination process of the first target position of the first indication mark and the second target position of the second indication mark, so that the first indication mark and the second indication mark are not located at the center of the display screen as far as possible, and the first indication mark and the second indication mark are not located at the center of the display screen when the antenna optimum direction of the satellite antenna is not aligned with the satellite direction.
Wherein, the aforementioned controlling the second indication mark to move correspondingly in response to the operation of adjusting the placement posture of the electronic device may include: responding to the adjustment operation of the placement posture of the electronic device, redetermining the second target position displayed on the display screen by the second indicating mark in the current placement posture of the electronic device 1000, and controlling the second indicating mark to be displayed at the redetermined second target position.
In the operation of adjusting the placement posture of the electronic device, the second target position displayed on the display screen by the second indicator can be redetermined every preset time in the current placement posture of the electronic device, and the second indicator is controlled to be displayed in the redetermined second target position. The preset time can be a short distance such as 0.2 second, so that the user sees the second indication mark as moving on the display screen more smoothly due to effects such as visual residue.
The second target position displayed on the display screen by the second indicator mark in the current placement posture of the electronic device 1000 is determined again, which may specifically refer to the aforementioned manner of determining the second target position, and is not described herein again.
Please refer to fig. 12, which is a schematic diagram of a first indication mark and a second indication mark displayed on the display screen 500 according to some embodiments of the present application. As shown in fig. 12, the first indicator mark B1 includes a center point B11 and a ring-shaped area B12 surrounding the center point B11, the center point B11 is used for characterizing the optimal direction of the antenna, and the ring-shaped area B12 is used for characterizing the sub-optimal direction of the antenna. Wherein the method further comprises: in controlling the second indicator B2 to move correspondingly in response to the adjustment operation of the placement posture of the electronic device 1000, when the second indicator B2 moves into the annular region B12 in the first indicator B1, a first prompt signal is controlled to be generated.
Since the annular region B12 is used to represent a sub-optimal direction of the antenna, and when the satellite direction is substantially the same as the sub-optimal direction of the antenna, the antenna gain of the satellite antenna 400 is greater than or equal to the preset threshold, when the second indicator B2 moves into the annular region B12 of the first indicator B1, the user is reminded by generating the first prompt signal, so that the user does not need to adjust the placement posture of the electronic device 1000, timely reminding can be effectively performed, and the adjustment time can be reduced. The preset threshold is the threshold which meets the better communication quality of the satellite antenna and is a value determined in advance through experiments and the like.
In other embodiments, the method also includes: responding to the adjustment operation of the placement posture of the electronic device 1000, calculating the antenna gain of the satellite antenna 200 in the process of adjusting the placement posture of the electronic device, and controlling to generate a first prompt signal when the antenna gain of the satellite antenna 200 is greater than or equal to a preset threshold value. How to calculate the antenna gain is not the protection focus of the present application, and the antenna gain of the satellite antenna 200 may be calculated by some existing antenna gain algorithms.
That is, since the annular region B12 is used to represent the antenna sub-optimal direction, when the satellite direction is substantially the same as the antenna sub-optimal direction, the antenna gain of the satellite antenna 400 is greater than or equal to the preset threshold, and therefore, the antenna gain of the satellite antenna 400 is greater than or equal to the preset threshold, and the second indicator B2 moves into the annular region B12 of the first indicator B1, which correspond to each other. Therefore, in 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, the first prompt signal is controlled to be generated.
In some embodiments, the first prompt signal may be a voice prompt signal, for example, outputting a voice content of "the current posture has reached a better state". In some embodiments, the first alert signal may be a vibration alert signal, alerting the user by vibration. In some embodiments, the first prompt signal may also change a display parameter and/or a display manner controlling the annular region B12, the display parameter may include one of a color, a pattern, the display manner may include a flashing display, and the like. Thus, 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 comprises: when the second indicating mark moves to the central point in the first indicating mark, a second prompting signal is controlled to be generated. The second prompt signal may also be a voice prompt signal, for example, outputting a voice content such as "the current posture has reached the best state". The second prompt signal can 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 may also change a display parameter and/or a display manner controlling the center point B11, the display parameter may include one of a color, a pattern, the display manner may include a flashing display, and the like. Thus, the user is prompted that the antenna optimum direction is already the same as the satellite direction in the current placement attitude, i.e., the current antenna gain of the satellite antenna 400 is already optimum.
In some embodiments, the display parameters of the annular region B12 and the center point B11 are different, and the display parameters include at least one of color and pattern, so that the annular region B12 and the center point B11 can be effectively distinguished, and a user can visually distinguish whether the second indication mark B2 is currently moved to the annular region B12 or the center point B11.
The position and size of the annular region B12 can be determined according to the position set of the antenna suboptimal direction mapping on the display screen 500. The directions within a certain angle from the optimal direction of the antenna are all the sub-optimal directions of the antenna, and therefore, the mapping onto the display screen 500 is the annular region B12.
Wherein, as shown in fig. 12, the second indication mark B2 can be a satellite pattern to more intuitively show the direction of the satellite.
Please refer to fig. 13, which is a schematic diagram illustrating that the second indicator B2 moves along with the change of the placement posture of the electronic device 1000 according to an embodiment of the present application.
As shown in fig. 13, the electronic device 1000 is taken as an example of a front view, i.e., the display screen 500 of the electronic device 1000 faces the user, the top end faces upward, and the bottom end faces downward. When the electronic device 1000 is rotated clockwise about the X-axis, the second indicator mark B2 moves upward in the display screen 500 at the viewing angle shown in fig. 13, and when the electronic device 1000 is rotated counterclockwise about the X-axis, the second indicator mark B2 moves downward in the display screen 500 at the viewing angle shown in fig. 13. When the electronic device 1000 rotates clockwise about the Y-axis, the second indicator mark B2 moves leftward in the display screen 500 at the viewing angle shown in fig. 13, and when the electronic device 1000 rotates counterclockwise about the Y-axis, the second indicator mark B2 moves rightward in the display screen 500 at the viewing angle shown in fig. 13. When the electronic device 1000 rotates counterclockwise about the Z-axis, the second indicator mark B2 moves clockwise in the display screen 500 at the viewing angle shown in fig. 13, and when the electronic device 1000 rotates clockwise about the Z-axis, the second indicator mark B2 moves counterclockwise in the display screen 500 at the viewing angle shown in fig. 13.
The clockwise rotation and the anticlockwise rotation are rotation states when viewed from the positive half shaft of the corresponding coordinate axis.
Please refer to fig. 14, which is a simulation diagram illustrating that the second indicator mark B2 is gradually aligned with the first indicator mark B1 according to an embodiment of the present application. As shown in (a) of fig. 14, in the initial state, the second indicator mark B2 is located at the upper left of the first indicator mark B1, so that the second indicator mark B2 needs to be moved rightward, downward and/or clockwise, as shown in (B) - (e) of fig. 14, by rotating the electronic apparatus 1000 counterclockwise about the Z axis while rotating the electronic apparatus 1000 counterclockwise about the X axis, the second indicator mark B2 can be gradually brought closer to the first indicator mark B1 until reaching a state where the second indicator mark B2 and the first indicator mark B1 are overlapped or nearly overlapped as shown in (e) of fig. 14.
Referring to fig. 15, a flowchart of a method for guiding and adjusting a pointing direction of a satellite antenna according to another embodiment of the present application is shown, where the method is applied to an electronic device, and the electronic device includes the satellite antenna and a display screen, as shown in fig. 15, the method includes:
