In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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, but 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.
Compared with 4G, the current 5G MIMO antenna weight planning improves the complexity, the manual antenna weight planning adopting 4G is difficult to seamlessly meet the actual coverage requirement, the requirement on planning designers is high through manual planning, the implementation difficulty is high, and the efficiency is lower. Accordingly, the embodiment can introduce an image recognition technology to perform three-dimensional imaging on buildings in the coverage area of the 5G base station, generate N-beam and m-beam plans of the 5G MIMO antenna based on the survey design data and the MIMO antenna weight set by the MIMO antenna manufacturer, realize seamless combination of antenna weight planning and actual coverage requirements, and avoid the problem of high difficulty in manual analysis and configuration of the MIMO antenna weight. The present embodiment will be described in detail below.
As shown in fig. 1, the method for setting weights of MIMO antennas includes the following steps:
step 101: and acquiring the stereo imaging information of buildings in the coverage range of the 5G base station.
In this step, specifically, when setting the MIMO antenna weight of the station, the stereo imaging information of the building in the coverage area of the 5G base station may be obtained first, so that the setting of the MIMO antenna weight may be performed based on the stereo imaging information of the building, and then the MIMO antenna with the set antenna weight may cover all the buildings, thereby achieving seamless matching between the antenna weight setting and the actual coverage requirement.
Step 102: and determining a coverage angle array between the building and the MIMO antenna of the 5G base station according to the stereo imaging information of the building.
In this step, specifically, after the stereo imaging information of the building is obtained, the coverage angle array between the building and the MIMO antenna of the 5G base station may be determined.
The coverage angle array comprises a horizontal dimension included angle and a vertical dimension included angle between a building and the MIMO antenna.
Specifically, by acquiring a horizontal dimension included angle and a vertical dimension included angle between a building and the MIMO antenna, how to set the beam antenna weight of the MIMO can be determined to perform full coverage on the building based on the horizontal dimension included angle and the vertical dimension included angle, and further seamless combination of the setting of the MIMO antenna and the full coverage of the building is realized.
Step 103: and setting the MIMO antenna weight of the 5G base station based on the pre-acquired MIMO antenna weight group and the coverage angle array of the MIMO antenna manufacturer.
In this step, specifically, the antenna manufacturer may provide an antenna weight manual including an MIMO antenna weight set, and at this time, after the coverage angle array is determined, the MIMO antenna weight set based on the MIMO antenna manufacturer obtained in advance may be set according to the determined coverage angle array, so that the MIMO antenna weight set based on the MIMO antenna weight set provided by the MIMO antenna manufacturer is close to the coverage angle array, thereby implementing seamless combination of the setting of the MIMO antenna weight and the actual coverage requirement.
In this way, in this embodiment, the three-dimensional imaging information of the building within the coverage area of the 5G base station is obtained first, the coverage angle array between the building and the MIMO antenna is determined according to the three-dimensional imaging information of the building, and finally, the MIMO antenna weight of the 5G base station is set based on the MIMO antenna weight set by the MIMO antenna manufacturer and the determined coverage angle array, so that the weight setting of the MIMO antenna by the building identified based on the image identification technology is realized, thereby realizing that the set MIMO antenna weight of the 5G base station is related to the building, and the scanning signal can cover the building, thereby realizing the seamless combination of the setting of the MIMO antenna weight and the actual coverage requirement, and avoiding the problems of low efficiency and high difficulty in manually setting the MIMO antenna weight.
Further, in this embodiment, when obtaining the stereoscopic imaging information of the building within the coverage area of the 5G base station, the installation position of the MIMO antenna may be determined first, and then the stereoscopic imaging information of the building within the coverage area of the 5G base station may be collected based on the installation position of the MIMO antenna.
Specifically, after the installation position of the MIMO antenna is determined, the three-dimensional imaging information of the building in the range covered by the 5G base station may be acquired with the installation position of the MIMO antenna as a reference, thereby ensuring the position accuracy of the acquired three-dimensional imaging information with respect to the MIMO antenna.
In addition, specifically, when the stereo imaging information of the building in the coverage area of the 5G base station is acquired, any one of the following modes can be used:
shooting a building in a coverage range of the 5G base station through a five-lens oblique photographic camera, and performing modeling processing on a shot image to obtain three-dimensional imaging information of the building; or the like, or, alternatively,
performing optical flow identification on a building in a coverage range of the 5G base station through an ultra-high speed camera, and performing modeling processing on an identified image to obtain three-dimensional imaging information of the building; or the like, or, alternatively,
visible light image recognition is carried out on the building within the coverage range of the 5G base station through a camera, and modeling processing is carried out on the recognized visible light image to obtain three-dimensional imaging information of the building; or the like, or, alternatively,
and carrying out video shooting on the building within the coverage range of the 5G base station through a multispectral camera, and carrying out modeling processing on the shot video to obtain the three-dimensional imaging information of the building.
The buildings in the coverage range of the 5G base station are identified and modeled by any mode, the three-dimensional imaging information of the buildings is obtained, and the image identification and the three-dimensional imaging of the buildings are realized, so that the information such as the distribution and the height of the buildings can be obtained, and a foundation is provided for determining the coverage angle array between the buildings and the MIMO antenna.
Furthermore, further, when determining the coverage angle array between the building and the MIMO antenna of the 5G base station according to the stereo imaging information of the building, the height of the building and the horizontal distance between the building and the MIMO antenna may be determined according to the stereo imaging information of the building, and then the horizontal dimension angle and the vertical dimension angle between the building and the MIMO antenna may be determined based on the height of the building and the horizontal distance between the building and the MIMO antenna.
Specifically, as shown in fig. 2, when determining the horizontal dimension angle between the building and the MIMO antenna based on the height of the building and the horizontal distance between the building and the MIMO antenna, a first horizontal distance between a first edge of the building in the horizontal direction and the MIMO antenna may be determined, a second horizontal distance between a second edge of the building opposite to the first edge in the horizontal direction and the MIMO antenna may be determined, a first angle may be obtained based on the first horizontal distance and the height of the building, a second angle may be obtained based on the second horizontal distance and the height of the building, and an absolute value of a difference between the first angle and the second angle may be determined as the horizontal dimension angle a between the building (represented by a right rectangular square on the horizontal line in the figure) and the MIMO antenna; of course, the first angle and the second angle are both corresponding angles of the MIMO antenna position. Therefore, the horizontal dimension included angle determined by the mode enables a beam scanning area which is the same as the horizontal dimension included angle to fully cover a building in the horizontal direction, and therefore seamless combination of setting of the MIMO antenna weight and actual covering requirements can be achieved when the MIMO antenna weight is set based on the horizontal dimension included angle.
Further, specifically, as shown in fig. 3, when determining the vertical dimension angle between the building and the MIMO antenna based on the height of the building and the horizontal distance between the building and the MIMO antenna, a third angle may be determined based on the horizontal distance between the building and the MIMO antenna and the height of the MIMO antenna, a height difference between the MIMO antenna and the building may be determined, a fourth angle may be determined based on the height difference and the horizontal distance between the building and the MIMO antenna, and an absolute value of a difference between the third angle and the fourth angle may be determined as the vertical dimension angle b between the building (indicated by a rectangular square on the right side of the horizontal line in the figure) and the MIMO antenna; of course, the third angle and the fourth angle are both corresponding angles of the MIMO antenna position. Therefore, the vertical dimension included angle determined by the mode enables a beam scanning area which is the same as the vertical dimension included angle to fully cover the building in the vertical direction, and therefore seamless combination of the setting of the MIMO antenna weight and the actual covering requirement can be achieved when the MIMO antenna weight is set based on the vertical dimension included angle.
Of course, it should be noted here that the horizontal dimension angle and the vertical dimension angle may also be obtained in other manners, and the manner of obtaining the horizontal dimension angle and the vertical dimension angle is not specifically limited herein.
In addition, further, when the MIMO antenna weights of the 5G base station are set based on the pre-obtained MIMO antenna weight set and coverage angle array of the MIMO antenna manufacturer, a target antenna weight matched with the coverage angle array may be selected from the MIMO antenna weight set, and the target antenna weight may be determined as the MIMO antenna weight of the 5G base station.
Preferably, the target antenna weight matched with the coverage angle array may be a target beam antenna weight in the MIMO antenna weight set that is the same as an angle in the coverage angle array; of course, when there is no target beam antenna weight with the same angle as that in the coverage angle array in the MIMO antenna weight group, the target antenna weight matched with the coverage angle array may be the target antenna weight with the smallest angle difference value between the MIMO antenna weight group and that in the coverage angle array, so that when the MIMO antenna weight is obtained through setting, beam scanning can fully cover the building, that is, seamless combination of setting of the MIMO antenna weight and actual coverage requirements is achieved.
Therefore, the coverage angle array between the building and the MIMO antenna is determined through the identified three-dimensional imaging information of the building, and finally, the MIMO antenna weight of the 5G base station is set based on the MIMO antenna weight set by the MIMO antenna manufacturer and the determined coverage angle array, so that the weight setting of the MIMO antenna by the building identified based on the image identification technology is realized, the seamless combination of the setting of the MIMO antenna weight and the actual coverage requirement is realized, and the problems of low efficiency and high difficulty in manual setting of the MIMO antenna weight are solved.
