In the calculation of the direction angle between the MR grid marking point and the corresponding antenna, the longitude and latitude of the grid center point of the MR grid marking point are used.

The optimal direction angle of the antenna is equal to the lower limit of the direction angle interval to which the largest ratio of the MR sampling points or the MR grid marking points belongs plus the horizontal main lobe width/2 of the antenna.
Taking the horizontal main lobe width of the antenna as 65 °, if the direction angle interval to which the largest MR sampling point or MR grid marking point belongs is 0 ° -65 °, the optimal direction angle of the antenna is 0 ° +65 °/2, which is 30.25 °.

further, in this embodiment, in step 302, calculating the distance and the direction angle between each MR sampling point or MR grid marking point and the corresponding antenna specifically includes:
First, the distance between each MR sampling point or MR grid marking point and the corresponding antenna is calculated according to the longitude and latitude in each MR sampling point or MR grid marking point data and the longitude and latitude of the corresponding antenna.
Specifically, fig. 4 is a distribution diagram of four-quadrant MR sampling points centered on an antenna position in the second embodiment of the present invention, as shown in fig. 4, in this embodiment, longitude and latitude of a corresponding antenna can be represented as: (SITE _ longitude, SITE _ landmark), the longitude and latitude in the MR sample points or the MR grid plot data are expressed as: (MR _ longitude, MR _ lane), calculating the distance between each MR sampling point or MR grid marking point and the corresponding antenna according to the longitude and latitude in each MR sampling point or MR grid marking point data and the longitude and latitude of the corresponding antenna, as shown in formula (1):
Wherein | MRDistance | is a distance between the MR sampling point or the MR grid marking point and the corresponding antenna.
then, according to the longitude and latitude in each MR sampling point or MR grid marking point data and the longitude and latitude of the corresponding antenna, the vertical distance or horizontal distance between each MR sampling point or MR grid marking point and the corresponding antenna is calculated.
The horizontal distance between each MR sampling point or MR grid marking point and the corresponding antenna is the length from the position of the antenna when each MR sampling point or MR grid marking point is mapped to the horizontal axis, and the vertical distance from each MR sampling point or MR grid marking point to the corresponding antenna is the length from the position of the antenna when each MR sampling point or MR grid marking point is mapped to the vertical axis.

Specifically, in this embodiment, the horizontal distance between each MR sampling point or MR grid marking point and the corresponding antenna is calculated according to the longitude and latitude in each MR sampling point or MR grid marking point data and the longitude and latitude of the corresponding antenna, which is specifically represented by formula (3).
and finally, calculating the direction angle of each MR sampling point or MR grid marking point and the corresponding antenna according to the longitude and latitude of each MR sampling point or MR grid marking point, the longitude and latitude of the corresponding antenna, the distance between each MR sampling point or MR grid marking point and the corresponding antenna, and the vertical distance or horizontal distance between each MR sampling point or MR grid marking point and the corresponding antenna.

If (MR _ length) and (MR _ variance < sitel _ variance), MR _ Azimuth is 270 °, i.e. if the MR sample point or MR grid index point longitude coincides with the antenna and the latitude is smaller than the antenna latitude, the antenna direction angle is 270 °.
If (MR _ Azimuth) and (MR _ longitudinal > sitejongitude), MR _ Azimuth is 0 °, that is, if the MR sample point or the MR grid index point latitude coincides with the antenna and the longitude is greater than the antenna longitude, the antenna direction angle is 0 °.
if (MR _ Azimuth) and (MR _ longitude < sitejongate), MR _ Azimuth is 180 °, that is, if the MR sample point or the MR grid index point latitude coincides with the antenna and the longitude is smaller than the antenna longitude, the antenna direction angle is 180 °.
If (MR _ length > SITE _ length) and (MR _ space > SITE _ length), MR _ Azimuth is 90 ° -arccos (| MR Map_x |/| MRDistance |), i.e. if the longitude and the latitude of the MR sampling point or the MR grid marking point are both greater than the longitude and the latitude of the antenna, the MR sampling point or the MR grid marking point is located in the first quadrant, and the direction angle of the antenna is 90 ° -arccos (| MR Map_x |/| MRDistance |).
If (MR _ length < SITE _ length) and (MR _ property < SITE _ property), MR _ Azimuth is 270 ° -arccos (| MR Map_x |/| MRDistance |), that is, if the longitude and the latitude of the MR sampling point or the MR grid marking point are both less than the longitude and the latitude of the antenna, the MR sampling point or the MR grid marking point is located in the third quadrant, and the direction angle of the antenna is 270 ° -arccos (| MR Map_x |/| MRDistance |).
If (MR _ lane < sitesj _ lane) and (MR _ length > sitesj _ length), MR _ Azimuth is 90 ° + arccos (| MRMap _ x |/| MRDistance |), i.e. if the longitude of the MR sample point or MR grid marker point is greater than the antenna longitude and the latitude is less than the antenna latitude, the MR sample point or MR grid marker point is in the second quadrant, and the direction angle of the antenna is 90 ° + arccos (| MRMap _ x |/| MRDistance |).
if (MR _ space) ("SITE _ space") and (MR _ distance < SITE _ distance), "MR _ Azimuth" + arccos (| MRMap _ x |/| MRDistance |), i.e., if the longitude of the MR sampling point or the MR grid marker point is less than the antenna longitude and the latitude is greater than the antenna latitude, the MR sampling point or the MR grid marker point is located in the fourth quadrant, and the antenna direction angle is 270 ° + arccos (| MRMap _ x |/| MRDistance |).
It is understood that the antenna direction angle may also be represented by an arcsine function and | MRMap _ Y | and | MRDistance |, which will not be described herein again in this embodiment.

and 305, positioning the optimal direction angle of the corresponding antenna according to the direction angle interval to which the MR sampling point or the MR grid marking point with the largest ratio belongs and the horizontal main lobe width of the antenna.
In this embodiment, the implementation manners of steps 303 to 305 are the same as the implementation manners of steps 103 to 105 in the first embodiment of the positioning method for an antenna optimal azimuth of the present invention, and are not described in detail herein.
Step 306, comparing the optimal direction angle of the antenna with the basic data direction angle of the antenna, judging whether the actual direction angle of the antenna has a problem, if not, ending, otherwise, executing step 307.
Further, in this embodiment, if the MR sampling point or MR grid marking point data is the MR sampling point or MR grid marking point data based on the assisted global positioning system, the optimal direction angle of the antenna is compared with the basic data direction angle of the antenna, and whether the actual direction angle of the antenna has a problem is determined, which specifically includes:
firstly, comparing the optimal direction angle of the antenna with the basic data direction angle of the antenna, and judging the size relation between the absolute value of the difference between the optimal direction angle of the antenna and the basic data direction angle of the antenna, a first threshold value and the width of a horizontal lobe of the antenna.
And then, judging whether the actual direction angle of the antenna has a problem or not according to the size relation between the absolute value of the difference between the optimal direction angle of the antenna and the basic data direction angle of the antenna, a first threshold value and the horizontal lobe width of the antenna.
The basic data direction angle of the antenna is determined when the base station antenna is planned and designed, and can be acquired from a corresponding basic database. The first threshold may be set from the summary of practical applications, in this embodiment, the first threshold may be flexibly set between 20 ° and 60 ° according to the horizontal lobe width of the antenna, for example, the first threshold may be 20 ° or a certain value between 20 ° and 60 °, which is not limited in this embodiment.
specifically, in this embodiment, if | the basic data direction angle of the antenna — the optimal direction angle of the antenna | ≦ the first threshold, it indicates that there is no problem in a normal error range, and indicates that there is no problem in the actual direction angle of the antenna.
If | the basic data direction angle of the antenna-the optimal direction angle | > is equal to or larger than the horizontal lobe width of the antenna, it indicates that the antenna may be reversely connected, and belongs to a wiring error in engineering construction, and further confirmation is needed.
If the horizontal lobe width of the antenna is ≧ the basic data directional angle of the antenna-the optimal directional angle of the antenna | ≧ the first threshold value, then it is said that the actual directional angle of the antenna may be shifted too much, there are three possible results: the first result is that the actual direction angle of the antenna is consistent with the optimal direction angle of the antenna, and the direction angle of the antenna basic data in the basic database manually maintained by the background is not consistent with the actual direction angle of the antenna, so that the direction angle of the antenna basic data in the background basic database only needs to be updated; the second result is that the basic data direction angle of the antenna in the basic database is consistent with the actual antenna direction angle, but not consistent with the optimal direction angle of the antenna, the actual direction angle of the antenna needs to be adjusted to the optimal direction angle; the third result is that the longitude and latitude of the background antenna are not consistent with the actual longitude and latitude, so whether the actual direction angle of the antenna has problems or not needs to be further confirmed according to three possible situations.
It should be noted that if one of the optimal azimuth angle of the antenna and the basic data azimuth angle of the antenna is located in the first quadrant and one is located in the fourth quadrant, the basic data azimuth angle of the antenna-the optimal azimuth angle of the antenna | needs to be adjusted to: the antenna azimuth with small azimuth value + 360-azimuth value is large. The antenna direction angle with small direction angle value is positioned in the first quadrant, and the antenna direction angle with large direction angle value is positioned in the fourth quadrant. If the antenna directivity angle with a small directivity angle value can be the antenna base data directivity angle, the antenna directivity angle with a large directivity angle value is the optimum directivity angle of the antenna, and if the antenna directivity angle with a small directivity angle value can be the optimum directivity angle of the antenna, the antenna directivity angle with a large directivity angle value is the antenna base data directivity angle
further, in this embodiment, if the MR sampling point or MR grid marking point data is the MR sampling point or MR grid marking point data located based on the round trip time, comparing the optimal direction angle of the antenna with the basic data direction angle of the antenna, and determining whether the actual direction angle of the antenna has a problem, specifically including:
Comparing the optimal direction angle of the antenna with the basic data direction angle of the antenna, and judging the size relation between the absolute value of the difference between the optimal direction angle of the antenna and the basic data direction angle of the antenna, a second threshold value and the horizontal lobe width of the antenna;
