As used in this specification and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
The embodiment of the invention provides an antenna control method, a control terminal and a communication system. The antenna control method is applied to a control terminal, the antenna comprises an antenna module and a pose adjusting device connected with the antenna module, and the control terminal is in communication connection with the antenna.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a control terminal and an antenna in electrical communication connection according to an embodiment of the present invention.
As shown in fig. 1, the control terminal 1 is connected in electrical communication with an antenna 2, wherein the antenna 2 comprises an antenna module 20 and a pose adjustment device 21. Specifically, the antenna module 20 is connected to the pose adjustment device 21, and the control terminal 1 is connected to the antenna module 20 and the pose adjustment device 21 in electrical communication when connected to the antenna 2 in electrical communication. The control terminal 1 receives and transmits signals through the antenna module 20 and controls the pose adjusting device 21 to adjust the pose of the antenna module.
In some embodiments, the pose adjustment device 21 may be a one-dimensional rotation device, and the pose adjustment device 21 may drive the antenna module 20 to rotate on a certain rotation plane, and the rotation plane may be a horizontal plane, a prone plane perpendicular to the horizontal plane, or other inclined planes not perpendicular to the horizontal plane, which is not limited herein.
In some embodiments, the pose adjusting device 21 may also be a two-dimensional rotating device, and the pose adjusting device 21 may drive the antenna module 20 to rotate on some two rotation planes; in addition, the pose adjusting device 21 may be a rotating device with more dimensions, which is not limited herein.
In some embodiments, the control terminal 1 forms a CPE (Customer Premise Equipment, customer premises equipment) product when connected in electrical communication with the antenna 2, the control terminal providing network services to other terminal devices by wired or wireless means.
Referring to fig. 2, fig. 2 is a flowchart of an antenna control method applied to a control terminal according to an embodiment of the present invention.
As shown in fig. 2, the antenna control method includes steps S10 to S12.
Step S10, a directional diagram of the antenna module is obtained, and a first rotation step length of the pose adjusting device in the rotation direction is determined according to a main lobe of the directional diagram.
It will be appreciated that the pattern of the antenna module 20, i.e. the radiation pattern of the antenna module 20, is a graphical depiction of the radiation characteristics of the antenna module 20. There are typically two or more lobes in the pattern, with the largest lobe being referred to as the main lobe and the remaining lobes being referred to as side lobes or side lobes, and the side lobes in the opposite direction from the main lobe being referred to as the rear lobes.
The first rotation step length is a unit angle of the pose adjusting device for adjusting the pose of the antenna module. In some embodiments, the first rotation step length refers to an included angle between two points when radiation intensities at two sides of the maximum radiation direction are reduced to a preset value by taking the maximum radiation direction of the main lobe as a center on a reference plane after determining the plane in which the rotation direction of the pose adjustment device is located as the reference plane.
The first rotation step may include one or more rotation steps, which correspond to the rotation direction of the pose adjustment device 21. Illustratively, when the pose adjustment device 21 is a one-dimensional rotation device, the first rotation step includes one rotation step corresponding to the rotation direction of the pose adjustment device 21. When the pose adjusting device 21 is a two-dimensional rotating device, the first rotating step length includes two rotating step lengths, which respectively correspond to the two rotating directions of the pose adjusting device 21.
In some embodiments, the pose adjustment device includes a horizontal rotation assembly for rotating the antenna module in a horizontal direction, and a pitch rotation assembly for rotating the antenna module in a pitch direction;
the determining a first rotation step length of the pose adjusting device in the rotation direction according to the main lobe of the direction diagram comprises the following steps:
and acquiring the half power lobe width of the main lobe of the directional diagram on the horizontal plane as a first horizontal step length, and acquiring the half power lobe width of the main lobe on the pitching plane as a first pitching step length.
It can be understood that when determining the first horizontal step length corresponding to the horizontal rotating component, because the plane in which the rotating direction of the horizontal rotating component is located is a horizontal plane, the horizontal plane is set as a reference plane, and the half power lobe width of the main lobe on the horizontal plane is obtained as the first horizontal step length. Similarly, when the first pitch step length corresponding to the pitch rotation assembly is determined, the plane in which the rotation direction of the pitch rotation assembly is located is the pitch plane, so that the pitch plane is set as the reference plane, and the half-power lobe width of the main lobe on the pitch plane is obtained as the first pitch step length.
The half power lobe width refers to the included angle between two points when the radiation intensity at two sides of the maximum radiation direction is reduced to half of the maximum radiation intensity on the reference plane by taking the maximum radiation direction of the main lobe as the center after the reference plane is determined.
In some embodiments, the antenna module 20 may be connected to a horizontal pivoting assembly, and in addition, the antenna module 20 may be connected to a vertical pivoting assembly, without limitation.
Referring to fig. 3, fig. 3 is a schematic structural diagram of an antenna according to an embodiment of the invention.
As shown in fig. 3, the pose adjusting device 21 adjusts the pose of the antenna module 20 by the horizontal rotation assembly 210 and the elevation rotation assembly 211. The pitching rotation component 211 is connected with the antenna module 20, and the pitching rotation component 211 can drive the antenna module 20 to rotate in the pitching direction; the horizontal rotation assembly 210 is connected with the pitching rotation assembly 211, and the antenna module 20 can be indirectly driven to rotate in the horizontal direction in the process of driving the pitching rotation assembly 211 to rotate in the horizontal direction by utilizing the horizontal rotation assembly 210.
Step S11, a first rotation range of the pose adjusting device in the rotation direction is obtained, the pose adjusting device is controlled to adjust the pose of the antenna module in the first rotation range according to the first rotation step length, and first signal intensity of the antenna module in each pose is obtained.
It is understood that the angular range in which the posture adjustment apparatus 21 can rotate in the rotation direction is the first rotation range. After the first rotation range and the first rotation step length are determined, the pose adjusting device 21 can be controlled to rotate in the first rotation range according to the first rotation step length so as to adjust the pose of the antenna module 20.
When the pose of the antenna module 20 changes, the signal intensity of the antenna module 20 also changes. When the first rotation step is used as a unit rotation step of the pose adjusting device 21 to adjust the pose of the antenna module 20, the recorded signal strength of the antenna module 20 under each pose is the first signal strength.
By way of example, assuming that the posture adjustment device 21 is a one-dimensional rotation device, assuming that the first rotation range is 0 ° -60 °, assuming that the first rotation step is 20 °, the posture adjustment device 21 is controlled to rotate to 0 °, 20 °, 40 °, and 60 °, respectively. In the process of adjusting the pose of the antenna module 20 in the first rotation range according to the first rotation step size by the pose adjusting device 21, the recorded first signal intensity includes: the signal intensity of the antenna module 20 when the pose adjustment device 21 is rotated to 0 °, the signal intensity of the antenna module 20 when the pose adjustment device 21 is rotated to 20 °, the signal intensity of the antenna module 20 when the pose adjustment device 21 is rotated to 40 °, and the signal intensity of the antenna module 20 when the pose adjustment device 21 is rotated to 60 °.
In some embodiments, the signal strength of the antenna module 20 may be the gain of the antenna module 20, the EIRP (Effective Isotropic Radiated Power, equivalent omni-directional radiation power) of the antenna module, or other parameters that may represent the signal quality of the antenna module, which is not limited herein.
In some embodiments, the acquiring a first rotation range of the pose adjusting device in a rotation direction, and controlling the pose adjusting device to adjust the pose of the antenna module in the first rotation range according to the first rotation step, and acquiring a first signal strength of the antenna module in each pose, includes:
acquiring a rotatable range of the horizontal rotation assembly in a horizontal direction as a first horizontal rotation range, and acquiring a rotatable range of the pitching rotation assembly in a pitching direction as a first pitching rotation range;
the horizontal rotation assembly is controlled to horizontally rotate the antenna module in the first horizontal rotation range according to the first horizontal step length, and the pitching rotation assembly is controlled to pitching and rotate the antenna module in the first pitching rotation range according to the first pitching step length so as to adjust the pose of the antenna module;
And recording the signal intensity of the antenna module under each pose as a first signal intensity.
It can be understood that the angular range of the horizontal rotation assembly 210 that can rotate in the horizontal direction is the first horizontal rotation range; accordingly, the angular range in which the pitch rotation component 211 can rotate in the pitch direction is the first pitch rotation range.
After determining the first horizontal rotation range and the first horizontal step, the first horizontal step may be used as a rotation step, and the horizontal rotation component 210 is controlled to drive the antenna module 20 to horizontally rotate within the first horizontal rotation range. Accordingly, after the first pitching rotation range and the first pitching step length are determined, the first pitching step length can be used as a rotation step length, and the pitching rotation component 211 is controlled to drive the antenna module 20 to perform pitching rotation within the first pitching rotation range. In this process, the signal intensity of the antenna module 20 at each pose is recorded as the first signal intensity. Wherein the number of first signal intensities matches the number of poses of the antenna module 20.
By way of example, assume a first horizontal rotation range of 0 ° to 360 °, a first horizontal step of 120 °, a first pitch rotation range of 0 ° to 45 °, and a first pitch step of 15 °. The number of rotational combinations and first signal strengths of the horizontal rotation assembly 210 and the pitch rotation assembly 211 within the first horizontal rotation range and the first pitch rotation range is shown in table one below.
A first step of,
| Horizontal rotating assembly | Pitch rotation assembly | First signal strength |
| 0° | 0° | Signal intensity 1a |
| 120° | 0° | Signal intensity 2a |
| 240° | 0° | Signal intensity 3a |
| 0° | 15° | Signal intensity 4a |
| 120° | 15° | Signal intensity 5a |
| 240° | 15° | Signal intensity 6a |
| 0° | 30° | Signal intensity 7a |
| 120° | 30° | Signal intensity 8a |
| 240° | 30° | Signal intensity 9a |
| 0° | 45° | Signal strength 10a |
| 120° | 45° | Signal intensity 11a |
| 240° | 45° | Signal intensity 12a |
And S12, screening out first target signal intensities from the first signal intensities, and controlling the pose adjusting device to adjust the antenna module to a first pose corresponding to the first target signal intensities.
It can be understood that the number of the first signal intensities is matched with the number of the pose of the antenna module, and the first target signal intensity is one of the first signal intensities and is obtained by screening from the first signal intensities according to a preset rule.
Wherein, each first signal intensity has a mapping relationship with the rotation angle of the pose adjusting device 21, and after determining the first target signal intensity, the pose adjusting device 21 is rotated to the rotation angle corresponding to the first target signal intensity, so that the antenna module 20 can be adjusted to the first pose.
In some embodiments, the filtering the first target signal strength from the first signal strengths, and controlling the pose adjusting device to adjust the antenna module to a first pose corresponding to the first target signal strength, includes:
Determining the maximum value in each first signal intensity as a first target signal intensity;
acquiring a horizontal rotation angle corresponding to the horizontal rotation assembly as a first horizontal angle under the first target signal intensity;
acquiring a pitching rotation angle corresponding to the pitching rotation assembly as a first pitching angle under the first target signal intensity;
the horizontal rotation assembly is controlled to rotate to the first horizontal angle, and the pitch rotation assembly is controlled to rotate to the first pitch angle.
It can be understood that the first horizontal angle is the rotation angle of the horizontal rotation component 210 when the signal strength of the antenna module 20 is the first target signal strength; similarly, the first tilt angle is the rotation angle of the tilt assembly 211 when the signal strength of the antenna module 20 is the first target signal strength. And the first pose is the pose corresponding to the antenna module 20 when the signal intensity of the antenna module 20 is the first target signal intensity.
Illustratively, as shown in the above table one, assuming that the "signal intensity 9a" is determined to be the first target signal intensity, at this time, the horizontal rotation angle of the horizontal rotation assembly 210 corresponding to the "signal intensity 9a" is 240 °, and the pitch rotation angle of the pitch rotation assembly 211 corresponding to the "signal intensity 9a" is 30 °. The first horizontal angle is determined to be 240 deg. and the first pitch angle is determined to be 30 deg.. After the horizontal rotation assembly 210 is controlled to rotate to 240 ° and the pitch rotation assembly 211 is controlled to rotate to 30 °, the pose of the antenna module 20 is the first pose, and at this time, the signal strength of the antenna module 20 may reach the first target signal strength.
In some embodiments, after the controlling the pose adjustment device adjusts the antenna module to a first pose corresponding to the first target signal strength, the method further comprises:
calculating the ratio of the first rotation step length to a preset numerical value as a second rotation step length, acquiring a first rotation angle of the pose adjusting device when the antenna module is in the first pose, and determining a second rotation range according to the first rotation angle and the preset step length;
controlling the pose adjusting device to adjust the pose of the antenna module in the second rotation range according to the second rotation step length, and obtaining second signal intensity of the antenna module under each pose;
and screening out second target signal intensities from the second signal intensities, and controlling the pose adjusting device to adjust the antenna module to a second pose corresponding to the second target signal intensities.
It can be understood that the first rotation step length is divided by a preset value, and the division result is the second rotation step length. In addition, when the antenna module 20 is in the first position, the current rotation angle of the position adjusting device 21 is the first rotation angle.
And determining the second rotation range by taking the first rotation angle as a reference value and taking a preset step length as a distance. For example, assuming that the first rotation angle is w0 and the preset step is w1, a range of w0-w1 to w0+w1 is determined as the second rotation range.
After determining the second rotation range and the second rotation step, the pose adjusting device 21 is controlled to rotate in the second rotation range by taking the second rotation step as a unit to adjust the pose of the antenna module 20.
When the pose of the antenna module 20 changes, the signal intensity of the antenna module 20 also changes. When the second rotation step length is used as the unit rotation step length of the pose adjusting device 21 to adjust the pose of the antenna module 20, the recorded signal strength of the antenna module 20 under each pose is the second signal strength.
Wherein, each second signal intensity has a mapping relationship with the rotation angle of the pose adjusting device 21, and after selecting the maximum value from the second signal intensities as the second target signal intensity, the pose adjusting device 21 is rotated to the rotation angle corresponding to the second target signal intensity, so that the antenna module 20 can be adjusted to the second pose.
It can be understood that in the process of controlling the pose adjusting device 21 to adjust the pose of the antenna module 20 within the first rotation range according to the first rotation step length to determine the first target signal strength and controlling the pose adjusting device 21 to adjust the antenna module 20 to the first pose corresponding to the first target signal strength, coarse adjustment of the pose of the antenna module 20 is completed, so that the antenna module 20 can quickly obtain good signal strength.
And in the process of controlling the pose adjusting device 21 to adjust the pose of the antenna module 20 in the second rotation range according to the second rotation step length to determine the second target signal strength and controlling the pose adjusting device 21 to adjust the antenna module 20 to the second pose corresponding to the second target signal strength. The fine adjustment of the pose of the antenna module 20 is completed, so that the antenna module can obtain better signal strength.
In some embodiments, the calculating the ratio of the first rotation step to the preset value as the second rotation step, and obtaining the first rotation angle of the pose adjusting device when the antenna module is in the first pose, and determining the second rotation range according to the first rotation angle and the preset step includes:
taking the ratio of the first horizontal step length to a preset value as a second horizontal step length, and taking the ratio of the first pitching step length to the preset value as a second pitching step length;
determining a second horizontal rotation range by taking the first horizontal angle as a reference value and the first horizontal step length as a radius;
and determining a second pitching rotation range by taking the first pitching angle as a reference value and taking the first pitching step length as a radius.
It can be understood that dividing the first horizontal step length by a preset value, and the obtained division result is the second horizontal step length; let a be the first horizontal angle and let a1 be the first horizontal step, the second horizontal rotation range is a-a1 to a+a1.
Similarly, dividing the first pitching step length by a preset value, wherein the obtained division result is the second pitching step length; let b be the first pitch angle and b1 be the first pitch step, the second pitch rotation range is b-b1 to b+b1.
In some embodiments, the controlling the pose adjusting device according to the second rotation step to adjust the pose of the antenna module in the second rotation range, and obtaining the second signal strength of the antenna module in each pose includes:
the horizontal rotation component is controlled to enable the antenna module to horizontally rotate in the second horizontal rotation range according to the second horizontal step length, and the pitching rotation component is controlled to enable the antenna module to pitching rotate in the second pitching rotation range according to the second pitching step length so as to adjust the pose of the antenna module;
and recording the signal intensity of the antenna module under each pose as second signal intensity.
It can be appreciated that after determining the second horizontal rotation range and the second horizontal step, the second horizontal step can be used as the rotation step, and the horizontal rotation assembly 210 is controlled to drive the antenna module 20 to horizontally rotate within the second horizontal rotation range. Accordingly, after the second pitching rotation range and the second pitching step length are determined, the second pitching step length can be used as the rotation step length, and the pitching rotation component 211 is controlled to drive the antenna module 20 to perform pitching rotation in the second pitching rotation range. In this process, the signal intensity of the antenna module 20 at each pose is recorded as the second signal intensity, and the number of the second signal intensities is matched with the number of poses of the antenna module 20.
In some embodiments, the preset value is a value greater than 1, the calculated second horizontal step size is less than the first horizontal step size, and the calculated second pitch step size is less than the first pitch step size. In this case, the pose adjustment full-time 21 may use a smaller step as a unit rotation step to fine tune the pose of the antenna module 20, so that the antenna module 20 obtains better signal strength.
By way of example, assuming a first horizontal angle of 240 ° and a first horizontal step of 120 °, the second horizontal rotation range is 180 ° to 300 °. Assuming that the first pitch angle is 30 ° and the first pitch step is 10 °, the second pitch rotation range is 20 ° to 40 °. Assuming a preset value of 2, the second horizontal step is 30 ° and the second pitch step is 5 °. The number of rotational combinations and second signal strengths of the horizontal rotation assembly 210 and the pitch rotation assembly 211 in the second horizontal rotation range and the second pitch rotation range is shown in table two below.
A second part,
In some embodiments, the filtering the second target signal strength from the second signal strengths, and controlling the pose adjustment device to adjust the antenna module to a second pose corresponding to the second target signal strength, includes:
determining the maximum value of each second signal intensity as a second target signal intensity;
acquiring a horizontal rotation angle corresponding to the horizontal rotation assembly as a second horizontal angle under the second target signal intensity;
acquiring a pitching rotation angle corresponding to the pitching rotation assembly as a second pitching angle under the second target signal intensity;
and controlling the horizontal rotation assembly to rotate to the second horizontal angle and controlling the pitching rotation assembly to rotate to the second pitching angle.
It can be understood that the second horizontal angle is the rotation angle of the horizontal rotation component 210 when the signal strength of the antenna module 20 is the second target signal strength; similarly, the second tilt angle is the rotation angle of the tilt assembly 211 when the signal strength of the antenna module 20 is the second target signal strength. And the second pose is the pose corresponding to the antenna module 20 when the signal intensity of the antenna module 20 is the second target signal intensity.
Illustratively, as shown in table two above, it is assumed that "signal strength 22b" is determined to be the second target signal strength because the horizontal rotation angle of the horizontal rotation assembly 210 corresponding to "signal strength 22b" is 210 ° and the pitch rotation angle of the pitch rotation assembly 211 corresponding to "signal strength 22b" is 40 °. The second horizontal angle is determined to be 210 deg. and the second pitch angle is determined to be 40 deg.. At this time, after the horizontal rotation assembly 210 is controlled to rotate to 210 ° and the pitch rotation assembly 211 is controlled to rotate to 40 °, the pose of the antenna module 20 is the second pose, and at this time, the signal intensity of the antenna module 20 may reach the second target signal intensity.
In some embodiments, the antenna module includes a parabolic reflecting surface and an antenna array, the antenna array being a feed of the parabolic reflecting surface;
referring to fig. 3, fig. 3 is a schematic structural diagram of an antenna according to an embodiment of the invention.
As shown in fig. 3, the antenna module 20 includes a parabolic reflecting surface 201 and an antenna array 202, and the antenna array 202 is a feed source of the parabolic reflecting surface 201.
When the antenna module 20 transmits a signal, the antenna array 202 radiates the signal to be transmitted in the direction of the parabolic reflecting surface 201, and the signal to be transmitted is reflected by the parabolic reflecting surface 201 and then transmitted to the base station along the normal parallel radiation of the parabolic reflecting surface 201. Correspondingly, when the antenna module 20 receives the signal to be received from the base station, the signal to be received is reflected by the parabolic reflecting surface 201 and then converged into the antenna array 202.
