[0002] Currently, lens antennas are typically spherical or cylindrical in shape. These shapes are difficult to install and have low accuracy during engineering installation, resulting in poor coverage and difficulty achieving the desired effect. To address this, researchers have proposed calibrating the azimuth and downtilt angles of lens antennas by observing at the coverage target point.

[0030] In order to better understand the embodiments of the present application, the technical terms involved in the embodiments of the present application are explained as follows:

[0031] Antenna: A device that can effectively radiate electromagnetic waves in a specific direction in space or effectively receive electromagnetic waves from a specific direction in space.

[0033] Azimuth: refers to the angle formed by rotating the antenna horizontally clockwise from the north direction to the plane where the antenna is located.

[0034] Example 1

[0035] Currently, for spherical or cylindrical antennas, the antennas are usually calibrated during installation by observing the target point. However, when the coverage range of the target antenna cannot reach the target point, the corresponding observation point cannot be set up, making the calibration method unfeasible.

[0036] In order to solve the above problems, an embodiment of the present application provides a method embodiment of an antenna calibration method. The following will take a spherical antenna as an example to illustrate the specific implementation process of the antenna calibration method of the embodiment of the present application.

[0037] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0038] Figure 1 is a flow chart of an optional antenna calibration method according to an embodiment of the present application, such as Figure 1 As shown, the method includes at least steps S102-S106, wherein:

[0039] Step S102: Acquire the downtilt angle and azimuth angle of the target antenna, and determine a plurality of first marker bars and a plurality of second marker bars to be observed according to the azimuth angle and the downtilt angle.

[0040] In the technical solution provided in step S102, the target antenna can be a lens antenna such as a spherical antenna or a quasi-cylindrical antenna. The first marker strips and the second marker strips are used to determine the downtilt angle and azimuth angle, respectively. The first marker strips are distributed in pairs between the top and bottom of the target antenna, which can be understood as the first marker strips being symmetrically distributed in the upper and lower halves of the spherical antenna. The second marker strips are distributed on the antenna surface of the target antenna at different orientations perpendicular to the equator, which can be understood as the second marker strips being equally spaced at different orientations perpendicular to the equator.

[0041] Step S104: Obtain the coverage range and installation point of the target antenna, and determine multiple observation points based on the coverage range and installation point.

[0042] In the technical solution provided in step S104, the coverage range of the target antenna and the installation point of the base station where the target antenna is installed are obtained. Multiple observation points are then determined based on the coverage range and installation point. These observation points can be coverage points within the coverage range or alternative observation points that can be used to replace coverage points. This allows for observation and calibration of the target antenna's downtilt and azimuth angles by establishing other observation points when the target antenna cannot reach the coverage point, such as on elevated railway tracks above a lake or on a moving high-speed train.

[0043] Step S106 , at multiple observation points, respectively detect the downtilt angle and azimuth angle of the target antenna based on the multiple first marker bars and the multiple second marker bars to obtain detection results, and calibrate the downtilt angle and azimuth angle of the target antenna based on the detection results.

[0044] In the technical solution provided in step S106, since the azimuth angle and the downtilt angle are two important parameters that describe the antenna orientation in the mobile communication network, whether they meet the preset installation requirements to achieve the preset coverage range of the antenna is crucial to the antenna performance. In the embodiment of the present application, regarding the detection of the downtilt angle and the azimuth angle, it is possible to determine whether the downtilt angle of the spherical antenna is correct by detecting at multiple observation points based on multiple first markers corresponding to the downtilt angle of the target antenna; at the same time, it is possible to determine whether the azimuth angle of the spherical antenna is correct by detecting at multiple observation points based on multiple second markers corresponding to the azimuth angle of the target antenna. Then, based on the detected detection results, the downtilt angle and azimuth angle of the target antenna are calibrated so that the radiation direction and coverage range of the target antenna can meet the preset installation standards to ensure that the signal can be effectively transmitted and covered. Therefore, the above detection results can be understood as whether the settings of the azimuth angle and downtilt angle of the target antenna meet the expected installation standards so that the radiation angle and coverage range of the target antenna reach the expected values.

[0045] Based on the scheme defined by the above steps S102 to S106, it can be known that in an embodiment, the downtilt angle and azimuth angle of the target antenna are obtained, and multiple first marker bars and multiple second marker bars to be observed are determined based on the azimuth angle and the downtilt angle, wherein the first marker bars are distributed in pairs from the top to the bottom of the target antenna, and the second marker bars are distributed on the antenna surface of the target antenna at different orientations perpendicular to the equator; the coverage range and installation point of the target antenna are obtained, and multiple observation points are determined based on the coverage range and the installation point; at multiple observation points, the downtilt angle and azimuth angle of the target antenna are respectively detected based on the multiple first marker bars and the multiple second marker bars to obtain detection results, and the downtilt angle and azimuth angle of the target antenna are calibrated based on the detection results.

[0046] It can be seen that through the technical solution of the embodiment of the present application, when the target antenna cannot reach the coverage point, the downtilt angle and azimuth angle of the target antenna can also be detected at other alternative observation points to determine whether they are correct, and the downtilt angle and azimuth angle of the target antenna can be calibrated according to the detection results, so that the installation accuracy of the target antenna is higher, thereby solving the technical problem of the related technology that when installing a spherical antenna, the azimuth angle and downtilt angle of the spherical antenna are difficult to calibrate to the preset installation standard during the installation process, resulting in poor coverage effect of the spherical antenna.

[0047] The above method of this embodiment is further introduced below.

[0048] Before executing step S102, a first marker strip for calibrating the target antenna's downtilt angle and a second marker strip for calibrating the target antenna's azimuth angle are first placed on the target antenna. Since these first marker strips are closely spaced on the upper and lower halves of the spherical antenna, they are each assigned a different color to facilitate identification and subsequent observation. Therefore, the first marker strips can be referred to as marker color strips. The second marker strips are evenly spaced on the target antenna surface at multiple locations perpendicular to the antenna equator. Therefore, to distinguish them from the aforementioned marker color strips, these second marker strips can be referred to as marker objects.

[0049] Further, combined with Figure 2 The spherical antenna shown illustrates how to set the marking color band and the marking object respectively.

[0050] Regarding the setting of the marking color band, in an embodiment of the present application, a quarter-circle angular scale can be set from the top of the spherical antenna to the equator of the spherical antenna to mark the downtilt angle range [0, 90°], and the downtilt angle range [0, 90°] can be divided into multiple downtilt angle ranges with a step size of β angle, wherein each downtilt angle range can be marked with a marking color band of a different color based on the angular scale. Therefore, the relationship between the above-mentioned marking color band and the downtilt angle range can be understood as follows: if the step size is set to β angle, the downtilt angle starting range is n*β, the downtilt angle ending range is (n+1)*β, and the sphere radius is R, then the starting position of the marking color band is set at an arc length of n*βπR / 180, and then the ending position of the marking color band is set at an arc length of (n+1)*βπR / 180 according to the size of the step size β, such as Figure 3 shown.

[0051] The correspondence between the above-mentioned mark color bands and the downtilt angle ranges can be expressed as follows: the downtilt angle range 1 marked by mark color band 1 and mark color band 1a is [0, β]; the downtilt angle range 2 marked by mark color band 2 and mark color band 2a is [β, 2β]; the downtilt angle range 3 marked by mark color band 3 and mark color band 3a is [2β, 3β]; the downtilt angle range 4 marked by mark color band 4 and mark color band 4a is [3β, 4β]; the downtilt angle range 5 marked by mark color band 5 and mark color band 5a is [4β, 5β]; the downtilt angle range 6 marked by mark color band 6 and mark color band 6a is [5β, 6β], ..., the downtilt angle range marked by mark color band N and mark color band Na is [(N-1)β, Nβ].

[0052] It should be noted that the number of groups of marking color bands 1 to N in the upper half of the spherical antenna and marking color bands 1a to Na in the lower half can be determined according to the actual downtilt angle range of the antenna and the preset tilt angle step. The smaller the tilt angle step, the more accurate the detection accuracy.

[0053] Regarding the setting of marker objects, in an embodiment of the present application, marker objects 1, 2, 3, and 4 can be set at the center position of the surface perpendicular to the equator of the spherical antenna, and rotated 90°, 180°, and 270° in sequence, a total of 4 orientations. The setting method of the marker objects here is only described as an example, and the number of marker objects set specifically can be adaptively adjusted based on actual applications.

[0054] To show in detail Figure 2 The various marking strips and marking objects on the spherical antenna shown, Figure 4 Further display of the three-view diagram of the spherical antenna, through Figure 4 You can learn in detail about the various marking color bands and marking objects to be observed set on the spherical antenna in the embodiment of the present application.

[0055] As an optional implementation, in the technical solution provided in the above-mentioned step S102, the method may include: obtaining the azimuth angle and downtilt angle of the target antenna; determining a plurality of first marker bars between the top and the bottom of the target antenna according to the downtilt angle of the target antenna, wherein the first marker bars include: determining a first upper marker bar between the top and the equator of the target antenna, and determining a first lower marker bar between the bottom and the equator of the target antenna; and determining a plurality of second marker bars to be observed at a plurality of orientations perpendicular to the equator on the antenna surface of the target antenna according to the azimuth angle of the target antenna.

[0056] In this embodiment, the azimuth and downtilt angles can be measured using an azimuth inclinometer (Antenna Downtilt). The azimuth inclinometer is a software for measuring azimuth and downtilt angles on the Android platform. According to the functional description of the software itself, the back of the smart terminal on which the software is installed can be facing the target antenna, and the software can measure the azimuth and downtilt angles of the target antenna.

[0057] Then, based on the measured downtilt angle, the corresponding multiple first marker bars are determined, wherein the first marker bars correspond to the first upper marker bar in the upper half (i.e., between the top of the target antenna and the equator) and the first lower marker bar in the lower half (i.e., between the bottom of the target antenna and the equator); at the same time, based on the measured azimuth angle, the corresponding multiple second marker bars are determined, wherein the above-mentioned multiple second marker bars include: a preset number of marker bars in the marker bars on the antenna surface of the target antenna in multiple orientations perpendicular to the equator, and each marker bar is distributed at equal intervals. In the embodiment of the present application, in order to facilitate observation, four different orientations that divide the spherical antenna into four equal parts can be selected, such as 0°, 90°, 180°, and 270°.

[0058] As an optional implementation, in the technical solution provided in the above step S104, the method may include: taking any point within the coverage range of the target antenna as a first observation point; determining a second observation point equidistant from the installation point on an extension line of the line connecting the first observation point and the installation point based on the distance between the first observation point and the installation point; and determining third observation points located on both sides of the installation point on a perpendicular line connecting the first observation point and the installation point.

[0059] In this embodiment, the above-mentioned first observation point can be understood as any point within the coverage range of the target antenna, also called the coverage target point, and the second observation point and the third observation point can be understood as other observation points selected to replace the coverage target point when the target antenna cannot reach the coverage target point.

[0060] As an optional implementation, in the technical solution provided in step S106 above, the test can be divided into the following two cases according to the test requirements:

[0061] 1. At multiple observation points, the downtilt angle of the target antenna is detected based on multiple first markers to obtain a first detection result, wherein the first detection result is used to indicate whether the downtilt angle of the target antenna is correct.

[0062] Optionally, the above-mentioned process of detecting the antenna downtilt angle may include the following steps:

[0063] First, a third upper marker bar adjacent to the first upper marker bar and close to the equator of the target antenna, and a third lower marker bar adjacent to the first lower marker bar and close to the bottom of the target antenna are determined.

[0064] Then, determining whether the coverage range of the target antenna reaches the first observation point;

[0065] When the coverage range of the target antenna reaches the first observation point, if the first upper marker bar cannot be observed at the first observation point, but the first lower marker bar and the third upper marker bar can be observed, the first detection result is determined to be a correct downtilt angle; otherwise, the first detection result is determined to be an incorrect downtilt angle;

[0066] When the coverage range of the target antenna does not reach the first observation point, when the first lower marker bar is observed at the second observation point and the third lower marker bar cannot be observed, the first detection result is determined to be a correct downtilt angle; otherwise, the first detection result is determined to be an incorrect downtilt angle.

[0067] Specifically, Figure 5 is a schematic diagram of an optional method for determining the downtilt angle of a spherical antenna according to an embodiment of the present application, such as Figure 5 As shown, the spherical antenna is fixedly mounted on the pole of the base station tower. The downtilt angle range X of the target antenna is determined based on its current downtilt angle. The first upper marker bar Y located in the upper half and the first lower marker bar Ya located in the lower half corresponding to the downtilt angle range X are selected. At the same time, the third upper marker bar Y+1 adjacent to the first upper marker bar Y and close to the equator and the third lower marker bar Ya-1 adjacent to the first lower marker bar and close to the bottom of the target antenna are determined.

[0068] Determine whether the target antenna can cover the target location (i.e., the first observation point), where:

[0069] When the target antenna can reach the target coverage position, observe the first upper marker bar Y, the first lower marker bar Ya and the third upper marker bar Y+1 on the target antenna at the target coverage position. If the first upper marker bar Y cannot be seen at the target coverage position, but the first lower marker bar Ya and the third upper marker bar Y+1 can be seen, it means that the downtilt angle of the target antenna meets the expected installation requirements, that is, the first detection result is that the downtilt angle is incorrect; otherwise, it means that the downtilt angle of the target antenna does not meet the expected installation requirements, that is, the first detection result is that the downtilt angle is incorrect.

[0070] If the target antenna cannot reach the coverage target position, it is impossible to set up an observation point at the coverage target position to observe the azimuth angle of the target antenna. Therefore, an alternative observation point 1 (i.e., a second observation point) can be selected on the extension line connecting the installation point and the coverage target position. That is, the alternative observation point 1 is located at a position equidistant from the back of the tower where the target antenna is installed and the coverage target position. Observe the first lower marking bar Ya and the third lower marking bar Ya-1 on the target antenna at the alternative observation point 1. If the first lower marking bar Ya is visible at the alternative observation point 1, but the third lower marking bar Ya-1 is not visible, it means that the downtilt angle of the target antenna meets the expected installation requirements, that is, the first detection result is that the downtilt angle is incorrect. Otherwise, it means that the downtilt angle of the target antenna does not meet the expected installation requirements, that is, the first detection result is that the downtilt angle is incorrect.

[0071] 2. At multiple observation points, the azimuth angle of the target antenna is detected based on multiple second markers to obtain a second detection result, wherein the second detection result is used to indicate whether the azimuth angle of the target antenna is correct.

[0072] Optionally, the above-mentioned process of detecting the antenna azimuth angle may include the following steps:

[0073] First, determine whether the coverage range of the target antenna reaches the first observation point;

[0074] When the coverage range of the target antenna reaches the first observation point, if any first sub-marker bar among the plurality of second marker bars is located in the middle of the front view when observed at the first observation point, and the other two second sub-marker bars adjacent to the first sub-marker bar are displayed symmetrically in the front view and have the same display width, the second detection result is determined to be a correct azimuth angle; otherwise, the second detection result is determined to be an incorrect azimuth angle;

[0075] When the coverage range of the target antenna does not reach the first observation point, when observing any third sub-marker bar among the multiple second marker bars at the second observation point or the third observation point, it is located in the middle position of the front view, and the other two fourth sub-marker bars adjacent to the third sub-marker bar are displayed symmetrically in the front view and have the same display width, the second detection result is determined to be a correct azimuth angle; otherwise, the second detection result is determined to be an incorrect azimuth angle.

[0076] Among them, the above-mentioned first sub-logo bar, second sub-logo bar, third sub-logo bar and fourth sub-logo bar are any one of multiple second logo bars, and the first sub-logo bar and the second sub-logo bar are different second logo bars, the third sub-logo bar and the fourth sub-logo bar are different second logo bars, and the first sub-logo bar and the third sub-logo bar and the fourth sub-logo bar can be the same second logo bar, and the second sub-logo bar can also be the same second logo bar as the third sub-logo bar and the fourth sub-logo bar.

[0077] Specifically, Figure 6 is a schematic diagram of an optional method for determining the azimuth angle of a spherical antenna according to an embodiment of the present application, such as Figure 6 As shown, the spherical antenna is fixed on the base station's pole, and the target antenna is positioned according to its current azimuth angle. Figure 2 Three marker objects are selected from the four marker objects 1-4 shown to detect the azimuth angle.

[0078] Determine whether the target antenna can cover the target location (i.e., the first observation point), where:

[0079] When the target antenna can reach the target coverage position, the mark object 1 (i.e., one of the multiple second mark bars) on the target antenna at the target coverage position is located in the middle position of the front view, and the mark objects 2 and 3 adjacent to the mark object 1 are displayed symmetrically in the front view and have the same display width, which means that the azimuth angle of the target antenna meets the expected installation requirements, that is, the second detection result is that the azimuth angle is incorrect; otherwise, it means that the azimuth angle of the target antenna does not meet the expected installation requirements, that is, the second detection result is that the azimuth angle is incorrect.

[0080] In the case that the target antenna cannot reach the coverage target position, it is impossible to set up an observation point at the coverage target position to observe the azimuth of the target antenna. Therefore, an alternative observation point 1 (i.e., the second observation point) can be selected on the extension line connecting the installation point and the coverage target position, and alternative observation points 2 and 3 (i.e., the third observation point 3) can be selected on the left and right sides of the tower on the perpendicular line connecting the coverage target position and the tower. The distance between the above-mentioned alternative observation point 1 and the tower, and the distance between the alternative observation points 2 and 3 and the tower can be equal to or different from the distance between the tower and the first observation point. The specific distance can be adjusted in combination with actual application and is not specifically limited here. Observe the marker object at any of the above-mentioned alternative observation points 1, 2, and 3. If a marker object can be observed in the middle of the front view at the same time, and the two marker objects on both sides of the front view are displayed symmetrically and have the same width, then the azimuth of the target antenna meets the expected installation requirements, that is, the second detection result is that the azimuth is incorrect; otherwise, it means that the azimuth of the target antenna does not meet the expected installation requirements, that is, the second detection result is that the azimuth is incorrect.

[0081] It should be noted that the aforementioned observation marker object 1 set at the coverage target point, observation marker object 4 set at alternative observation point 1, observation marker object 2 set at alternative observation point 2, and observation marker object 3 set at alternative observation point 3 are merely examples. In actual application, the number of marker objects and the positions of the alternative observation points can be adjusted according to the actual application scenario. For example, six marker objects and five alternative observation points can be set, each observation point being used to observe multiple marker objects within the front view.

[0082] For example, Figure 7 This is a three-view diagram of a spherical antenna with an optional marking ribbon and a marking object according to an embodiment of the present application, as shown in FIG. Figure 7 As shown, the downtilt angle range of the spherical antenna is set to [0, 30°], the tilt angle step β is 5°, and according to Figure 3The angular scale of the spherical antenna shown is provided with 6 pairs of marking strips in the upper hemisphere and the lower hemisphere, respectively, which are recorded as marking strips 1 to 6 and marking strips 1a to 6a, and the correspondence between each marking strip and the downtilt angle range is as follows: the downtilt angle range 1 marked by marking strip 1 and marking strip 1a is [0, 5°], the downtilt angle range 2 marked by marking strip 2 and marking strip 2a is [5°, 10°], the downtilt angle range 3 marked by marking strip 3 and marking strip 3a is [10°, 15°], the downtilt angle range 4 marked by marking strip 4 and marking strip 4a is [15°, 20°], the downtilt angle range 5 marked by marking strip 5 and marking strip 5a is [20°, 25°], and the downtilt angle range 6 marked by marking strip 6 and marking strip 6a is [25°, 30°]. At the same time, a marker object 1 is set in the middle of the front of the antenna structure. The marker object 1 is a solid color ribbon connecting the upper hemisphere and the lower hemisphere. The marker object 1 is then rotated 90°, 180°, and 270° around the Z axis in sequence to be recorded as marker objects 2, 3, and 4.

[0083] The judgment process of the downtilt angle of the spherical antenna is as follows: set the preset downtilt angle of the spherical antenna to 28 degrees, and determine the corresponding color bands to be observed as mark color band 5, mark color band 6, mark color band 4a and mark color band 5a according to the downtilt angle range of the downtilt angle; then, judge whether the spherical antenna can reach the first observation point. If it can reach the first observation point, Figure 5 If the target coverage position shown cannot be seen with the mark color band 5, but the mark color band 6 and mark color band 4a can be seen, it is determined that the downtilt angle of the spherical antenna is installed correctly, otherwise it is incorrectly installed. Figure 5 The downtilt angle is detected at the alternative observation point 1 shown. Figure 5 When the marking color band 5a can be seen at the alternative observation point 1 shown, but the marking color band 4a cannot be seen, it is determined that the downtilt angle of the spherical antenna is installed correctly, otherwise it means that the installation is incorrect.

[0084] The process of judging the azimuth of the spherical antenna is as follows: judging whether the spherical antenna can reach the first observation point, and if it can reach the first observation point, Figure 6 At the target coverage position shown, if the marker object 1 is located in the middle of the front view and the marker objects 2 and 3 are displayed symmetrically and have the same width, it is confirmed that the azimuth angle of the spherical antenna is installed correctly. Otherwise, it means that the installation is incorrect. If it cannot be achieved, you can choose Figure 6 The azimuth angle is detected at the alternative observation point shown. Figure 6 The alternative observation point 1 (i.e., the second observation point) shown can show that the marker object 4 is located in the middle of the front view, and the marker objects 2 and 3 are symmetrically displayed and have the same width, or Figure 6The alternative observation point 2 (ie the third observation point) shown can show that the marker object 2 is located in the middle of the front view, and the marker objects 1 and 4 are symmetrically displayed and have the same width, or Figure 6 The alternative observation point 3 (i.e., the third observation point) shown shows that the marker object 3 is located in the middle of the front view, and the marker objects 1 and 4 are displayed symmetrically and have the same width. In the above three cases, it can be determined that the azimuth angle of the spherical antenna is installed correctly, otherwise it means that the installation is incorrect.

[0085] Furthermore, after obtaining the detection results of the downtilt angle and azimuth angle of the target antenna through the above steps, the downtilt angle and azimuth angle of the target antenna may be calibrated according to the following rules and the detection results:

[0086] When the first detection result shows that the downtilt angle is incorrect, the target antenna is adjusted up or down;

[0087] When the second detection result shows that the azimuth angle is incorrect, the target antenna is adjusted left and right.

[0088] Specifically, Figure 7 Take the spherical antenna shown as an example, using Figure 5 and Figure 6 The judgment method shown briefly describes the judgment and adjustment process of the target antenna's downtilt angle and azimuth angle, including:

[0089] exist Figure 7 The spherical antenna shown can achieve Figure 5 In the case of the target coverage position shown, if the marking color band 5 on the spherical antenna can be seen at the target coverage position, but the marking color band 6 and the marking color band 4a cannot be seen, the downtilt angle of the spherical antenna can be slightly adjusted downward and the test can be performed again. Figure 7 The spherical antenna shown cannot reach Figure 5 In the case of the target coverage position shown, it can be Figure 5 The downtilt angle is detected at the alternative observation point 1 shown. If the marker color band 5a cannot be seen at the alternative observation point 1, but the marker color band 4a can be observed, the downtilt angle of the spherical antenna can be slightly adjusted upward and detected again.

[0090] exist Figure 7 The spherical antenna shown can achieve Figure 6In the case of the target coverage position shown, if it is observed that the marker object 1 is not located in the middle of the front view at the target coverage position, and the width of the marker object 2 is greater than the display width of the marker object 3, it means that the installation of the spherical antenna is offset, and the spherical antenna can be fine-tuned to the right (i.e., in the direction of the marker object 3); if it is observed that the marker object 1 is not located in the middle of the front view at the target coverage position, and the width of the marker object 2 is less than the display width of the marker object 3, it means that the installation of the spherical antenna is offset, and the spherical antenna can be fine-tuned to the left (i.e., in the direction of the marker object 2). Similarly, Figure 7 The spherical antenna shown cannot reach Figure 6 In the case of the target coverage position shown, the azimuth angle of the spherical antenna is detected and adjusted in the same manner as described above at other alternative observation points 2 and 3.

[0091] Through the above steps, when the target antenna cannot reach the coverage target, the observation method can also be used to calibrate the azimuth and downtilt angles of the antenna, and this method can also be applied to cylindrical antennas. Therefore, the above antenna calibration scheme provided in the embodiment of the present application has a wider range of applicable scenarios.

[0094] The first acquisition module 81 is used to obtain the downtilt angle and azimuth angle of the target antenna, and determine multiple first marker bars and multiple second marker bars to be observed based on the azimuth angle and the downtilt angle, wherein the first marker bars are distributed in pairs from the top to the bottom of the target antenna, and the second marker bars are distributed on the antenna surface of the target antenna at different orientations perpendicular to the equator.

The plurality of second marker bars include: a preset number of marker bars among the marker bars at a plurality of orientations perpendicular to the equator on the antenna surface of the target antenna, wherein the marker bars are equally spaced.

[0096] The second acquisition module 82 is configured to acquire the coverage range and installation point of the target antenna, and determine a plurality of observation points based on the coverage range and installation point.

[0097] As an optional implementation, the above-mentioned second acquisition module 82 can also obtain multiple observation points in the following manner: take any point within the coverage range of the target antenna as the first observation point; based on the distance between the first observation point and the installation point, determine a second observation point that is equidistant from the installation point on the extension line of the line connecting the first observation point and the installation point; and determine third observation points located on both sides of the installation point on the perpendicular line connecting the first observation point and the installation point.

[0098] The calibration module 83 is used to detect the downtilt angle and azimuth angle of the target antenna at multiple observation points based on multiple first marker bars and multiple second marker bars, obtain detection results, and calibrate the downtilt angle and azimuth angle of the target antenna based on the detection results.

[0099] As an optional implementation, the calibration module 83 may detect the downtilt angle and azimuth angle of the target antenna according to the following rules:

[0100] 1. At multiple observation points, the calibration module 83 detects the downtilt angle of the target antenna based on multiple first markers to obtain a first detection result, wherein the first detection result is used to indicate whether the downtilt angle of the target antenna is correct;

[0101] Specifically, the downtilt angle of the target antenna can be detected as follows:

[0102] First, determining a third upper marker bar adjacent to the first upper marker bar and close to the equator of the target antenna, and a third lower marker bar adjacent to the first lower marker bar and close to the bottom of the target antenna;

[0103] Determine whether the coverage range of the target antenna reaches the first observation point;

[0104] When the coverage range of the target antenna reaches the first observation point, if the first upper marker bar cannot be observed at the first observation point, but the first lower marker bar and the third upper marker bar can be observed, the first detection result is determined to be a correct downtilt angle; otherwise, the first detection result is determined to be an incorrect downtilt angle;

[0105] When the coverage range of the target antenna does not reach the first observation point, when the first lower marker bar is observed at the second observation point and the third lower marker bar cannot be observed, the first detection result is determined to be a correct downtilt angle; otherwise, the first detection result is determined to be an incorrect downtilt angle.

[0106] 2. At multiple observation points, the calibration module 83 detects the azimuth of the target antenna based on multiple second markers to obtain a second detection result, wherein the second detection result is used to indicate whether the azimuth of the target antenna is correct.

[0107] Specifically, the azimuth angle of the target antenna can be detected as follows:

[0108] First, determine whether the coverage range of the target antenna reaches the first observation point;

[0109] When the coverage range of the target antenna reaches the first observation point, if any first sub-marker bar among the plurality of second marker bars is located in the middle of the front view when observed at the first observation point, and if the other two second sub-marker bars adjacent to the first sub-marker bar are displayed symmetrically in the front view and have the same display width, then the second detection result is determined to be a correct azimuth angle; otherwise, the second detection result is determined to be an incorrect azimuth angle;

[0111] Furthermore, after the calibration module 93 obtains the detection result, it can adjust the target antenna up and down when the first detection result is that the downtilt angle is incorrect; and adjust the target antenna left and right when the second detection result is that the azimuth angle is incorrect.
