The antenna engineering parameters are determined by the second mode, generally only before the base station is built and is not powered on and started, because the working parameter acquisition equipment is in a failure state due to the fact that the magnetic factors such as strong magnetic interference of the antenna and the like can cause the working parameter acquisition equipment to be in a failure state after the base station is powered on and operated, accurate measurement of the antenna engineering parameters of the base station in operation cannot be achieved, namely, in later maintenance, the antenna engineering parameters are still required to be measured manually, and the problem of low accuracy exists.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The accuracy of the antenna engineering parameters stated in the background section, which mainly include downtilt angle, azimuth angle, etc., is an important factor affecting the coverage quality of the antenna network. For example, if the downward inclination angle of the antenna is greater than the planned design value, the network coverage radius is reduced, and the situation of bad signals or even no signals may occur in the originally planned signal good area, resulting in user complaints; if the downward inclination angle is smaller than the planned design value, the network coverage radius is enlarged, signal interference is caused to the adjacent cell, the service quality of the user in the adjacent cell is poor, and the user complaint is caused. And if the antenna direction angle deviates from the planning design value, the antenna network coverage effect is also influenced.
In addition, in order to rapidly have network coverage capability and improve self competitiveness, operators can build large-scale wireless networks in a short period, construction quality is uneven due to shortened construction period, and corresponding antenna engineering parameters deviate from design values when a plurality of base station cells are built. Meanwhile, the antenna is hung at a high position and suffers from wind and rain for a long time, and the fixed point becomes loose after a long time, so that the antenna engineering parameters deviate from the planning design values. It can be seen that it is necessary to periodically determine the above antenna engineering parameters to check the accuracy of the parameters during the on-line operation of the base station.
However, in the existing methods for determining antenna engineering parameters, either an auxiliary tool is used for manual measurement for determination, or an engineering parameter acquisition device for measuring antenna engineering parameters can only acquire parameters before the base station is powered on and connected to the network, and if the base station is powered on and connected to the network and the network is in failure due to magnetic environment interference, manual measurement still needs to be performed by means of the auxiliary tool, so that not only is the operation cumbersome, but also the accuracy of the result is difficult to guarantee.
Therefore, it is necessary to provide an antenna engineering parameter determination scheme in the embodiment of the present invention, so as to improve the accuracy of the determined antenna engineering parameters.
The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present invention provides a method for determining antenna engineering parameters, where the method may specifically include:
step S101: a target image is acquired, the target image including an edge profile of a target side of the antenna.
Optionally, in the method for determining antenna engineering parameters according to the embodiment of the present invention, the step S101 may be specifically executed as:
and carrying out preset processing on the original image including the side surface of the target to obtain the target image.
It can be understood that, by performing the preset processing on the original image of the target side surface including the antenna, the target image including the edge profile of the target side surface of the antenna can be extracted to provide a basis for determining the antenna engineering parameters.
Optionally, the preset processing on the original image includes: the edge contour of the target side face of the antenna is recognized in the original image through an image processing edge detection technology, wherein the edge area of the target side face of the antenna can be converted into one color (such as white) and the non-edge area can be converted into another color (such as black), the original image is subjected to clipping processing on the basis of retaining the edge contour of the target side face of the antenna, and a new image generated after processing is used as the target image.
Step S103: from a plurality of target vertices of the edge profile, a first endpoint and a second endpoint of a centerline of the target side are determined.
Alternatively, in one embodiment of the present invention, the plurality of target vertices includes first through eighth vertices of the edge contour,
wherein the first outer loop long side of the edge profile is located between the first vertex and the second vertex, the second outer loop long side is located between the third vertex and the fourth vertex, the first inner loop long side of the edge profile is located between the fifth vertex and the sixth vertex, the second inner loop long side is located between the seventh vertex and the eighth vertex, and
the first outer ring long edge and the first inner ring long edge are positioned on one side of the central line, and the second outer ring long edge and the second inner ring long edge are positioned on the other side of the central line.
Referring specifically to fig. 2, as shown in fig. 2, the plurality of target vertices of the edge profile of the target side of the antenna include eight vertices, where a1 represents a first vertex, C1 represents a second vertex, B1 represents a third vertex, and D1 represents a fourth vertex, i.e., a1, C1, B1, and D1 are located at the outer circle of the edge profile, and a2 represents a fifth vertex, C2 represents a sixth vertex, B2 represents a seventh vertex, and D2 represents an eighth vertex, i.e., a2, C2, B2, and D2 are located at the inner circle of the edge profile.
Further, the step S103 may be specifically executed as follows:
respectively determining a first midpoint of a connecting line between the first vertex and the fifth vertex, a second midpoint of a connecting line between the third vertex and the seventh vertex, a third midpoint of a connecting line between the second vertex and the sixth vertex, and a fourth midpoint of a connecting line between the fourth vertex and the eighth vertex;
determining the midpoint of a connecting line between the first midpoint and the second midpoint as a first endpoint;
and determining the midpoint of the connecting line between the third midpoint and the fourth midpoint as a second endpoint.
It can be understood that based on the eight vertexes corresponding to the four corners of the edge profile of the target side surface of the antenna, two end points of the center line of the edge profile of the target side surface can be determined accurately and efficiently.
It should be noted that, in other specific embodiments of the present invention, the plurality of target vertices of the edge profile of the target side of the antenna may also include only four vertices, such as the four vertices a1, C1, B1, and D1 of the outer circle of the edge profile, or further such as the four vertices a2, C2, B2, and D2 of the inner circle of the edge profile, and further two endpoints of the center line may be determined based on the four vertices in a manner similar to the above-mentioned manner of determining two endpoints of the center line of the edge profile of the target side based on eight vertices, and preferably, the two endpoints are located on the inner circle short side or the outer circle short side of the edge profile respectively. Of course, other ways of determining the two end points of the center line of the edge profile of the target side of the antenna are possible to achieve the above object.
Step S105: and determining the downward inclination angle and the direction angle of the antenna according to the first coordinate and the second coordinate respectively corresponding to the first endpoint and the second endpoint in the rectangular coordinate system of the target image.
In the embodiment of the present invention, the downtilt angle and the direction angle of the antenna are determined based on the edge profile of the target side including the antenna, specifically, two end points of the center line of the target side are determined according to a plurality of target vertices of the edge profile of the target side, and then the downtilt angle and the direction angle are determined according to two coordinates respectively corresponding to the two end points in a rectangular coordinate system where the target image is located. Therefore, the edge profile of the target side face of the antenna is automatically identified, the downward inclination angle and the direction angle of the antenna are determined based on the edge profile, in the process of determining the antenna engineering parameters, manual measurement is not needed, the operation difficulty of a maintenance worker is reduced, and meanwhile the efficiency and the accuracy of determining the antenna engineering parameters are effectively improved.
For example, as shown in fig. 2, the coordinates of the eight vertices of the target side of the antenna in the rectangular coordinate system where the target image is located can be expressed as: a1 (x)1a，y1a)、B1(x1b，y1b)、C1(x1c，y1c)、D1(x1d，y1d)、A2(x2a，y2a)、B2(x2b，y2b)、C2(x2c，y2c) And D2 (x)2d，y2d). Then: the coordinate of the first midpoint A (not shown) of the connecting line between the first vertex A1 and the fifth vertex A2 can be expressed as (x)a，ya) Wherein x isa＝(x1a+x2a)/2，ya＝(y1a+y2a) 2; the coordinate of the second midpoint B (not shown) of the connecting line between the third vertex B1 and the seventh vertex B2 can be expressed as (x)b，yb) Wherein x isb＝(x1b+x2b)/2，yb＝(y1b+y2b) 2; the coordinate of the third midpoint C (not shown) of the connecting line between the second vertex C1 and the sixth vertex C2 can be expressed as (x)c，yc)，xc＝(x1c+x2c)/2，yc＝(y1c+y2c) 2; and the coordinate of the fourth midpoint D (not shown) of the line connecting the fourth vertex D1 and the eighth vertex D2 may be expressed as (x)d，yd)，xd＝(x1d+x2d)/2，yd＝(y1d+y2d)/2. Further, a midpoint of a connecting line between the first midpoint a and the second midpoint B may be determined as a first endpoint E, and the corresponding first coordinate is ((x)a+xb)/2，(ya+yb) 2) and the midpoint of the connecting line between the third midpoint and the fourth midpoint is determined as a second endpoint F, the corresponding second coordinate is ((x)c+xd)/2，(yc+yd) /2), then the line between E and F can be used as the target side of the antennaThe center line of the edge profile of (1).
Optionally, in the method for determining antenna engineering parameters according to the embodiment of the present invention, the scheme for determining the downtilt of the antenna in step S105 may be specifically implemented as follows:
determining a first difference value between a first abscissa value included in the first coordinates and a second abscissa value included in the second coordinates;
determining a second difference value between a first longitudinal coordinate value included in the first coordinate and a second longitudinal coordinate value included in the second coordinate;
and determining the downward inclination angle of the antenna according to the ratio of the first difference to the second difference.
It can be understood that, in the rectangular coordinate system where the target image is located, according to a ratio between a first difference between the first abscissa value and the second abscissa value and a difference between a second difference between the first ordinate value and the second ordinate value, a tangent function value of an included angle between a center line of the edge profile of the target side surface and the vertical direction can be known, and then an inverse tangent function operation is performed on the tangent function value, so that an included angle between the center line of the edge profile of the target side surface and the vertical direction, that is, a downtilt angle of the antenna can be determined accurately through efficient data processing without human involvement.
Optionally, in the method for determining antenna engineering parameters according to the embodiment of the present invention, the scheme for determining the direction angle of the antenna in step S105 may be specifically implemented as follows:
determining the inclination state of the antenna in the target image according to the first coordinate and the second coordinate;
and determining the direction angle of the antenna according to the inclination state.
It can be understood that, when determining the direction angle of the antenna, the tilt state of the antenna in the target image needs to be determined to accurately determine the direction angle of the antenna further based on the tilt state of the antenna.
Further, the above-mentioned scheme for determining the tilt state of the antenna in the target image according to the first coordinate and the second coordinate may be specifically implemented as follows:
if the first abscissa value included in the first coordinate is smaller than the second abscissa value included in the second coordinate, determining that the antenna is in a left-inclined state in the target image;
and if the first abscissa value is larger than the second abscissa value, determining that the antenna is in a right-inclined state in the target image.
It can be understood that the inclination state of the antenna in the target image is determined by judging the left-right position relationship of the first end point and the second end point in the target image, that is, the left-right position relationship of the first end point and the second end point in the target image is judged according to the magnitude relationship between the abscissa values respectively corresponding to the two end points of the center line, so that the inclination state of the antenna in the target image can be judged efficiently and accurately.
For example, as shown in fig. 2, if the abscissa value of the first end point E of the center line of the edge profile of the target side of the antenna is smaller than the abscissa value of the second end point F of the center line, it indicates that the antenna is in a left-inclined state in the target image; and as shown in fig. 3, if the abscissa value of the first end point E of the center line of the edge profile of the target side of the antenna is greater than the abscissa value of the second end point F of the center line, it indicates that the antenna is in a right tilt state in the target image.
Further, in a case that the information related to the original image of the target side surface including the antenna includes a shooting direction angle of the camera when the original image is acquired, the determining of the direction angle of the antenna according to the tilt state may be specifically performed as follows:
if the antenna is in a left inclined state, determining the difference between the shooting direction angle and 90 degrees as the direction angle of the antenna;
if the antenna is in a right-inclined state, the sum of the shooting direction angle and 90 degrees is determined as the direction angle of the antenna.
It can be understood that, in the case that it is determined that the antenna is in a left-inclined state in the target image, it indicates that the camera is located on the right side of the antenna when the original image of the side of the target including the antenna is acquired, and the direction angle of the antenna at this time may be a difference between a shooting direction angle of the camera when the original image is acquired and 90 degrees; and in the case that it is determined that the antenna is in the right-inclined state in the target image, it indicates that the camera is located on the left side of the antenna when the original image of the side of the target including the antenna is acquired, and the direction angle of the antenna at this time may be the sum of the shooting direction angle of the camera when the original image is acquired and 90 degrees.
Optionally, the shooting direction angle of the camera when the original image is acquired is included in the related information of the original image, and specifically, the related information of the original image may be acquired simultaneously in the process of extracting the target image based on the original image, and preferably, the related information of the original image may be EXIF (exchangeable image File) information including the shooting direction angle of the camera when the original image is acquired, where the camera that can be used to acquire the original image may be a camera of an unmanned aerial vehicle.
