It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. The specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.
It is noted that, in this document, relational terms such as "first" and "second," and the like, may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
Fig. 1 is a flowchart of an alignment method for a directional antenna of a high-speed rail network according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step 101: and acquiring position information and height information of a base station in a target high-speed rail scene, and longitude and latitude information of the target high-speed rail.
Specifically, in this step, the longitude and latitude information of the target high-speed rail and the position information and the height information of the base station in the target high-speed rail scene are measured by the global positioning system.
In some embodiments, for a target high-speed rail in a shutdown state, longitude and latitude information of the target high-speed rail is pre-stored in a base station edge cloud, and position information and height information of all base stations measured by a global positioning system are also pre-stored in the base station edge cloud, for example, GPS information and height information (N is an integer greater than or equal to 1) of N gnbs in a target high-speed rail scene are pre-stored in the base station edge cloud, that is, the GPS information and the height information of the N gnbs are position information and height information of N5G base stations.
In some embodiments, for a target high-speed rail in high-speed driving, a global positioning system is required to measure longitude and latitude information of the target high-speed rail in high-speed driving in real time, meanwhile, according to the longitude and latitude information of the target high-speed rail, position information and height information of a base station in a target high-speed rail scene are obtained, and the position information and the height information of the base station in the target high-speed rail scene can also be directly measured through the global positioning system.
Step 102: and determining the position information of the first base station based on the position information and the height information of the base station in the target high-speed rail scene and the latitude and longitude information of the target high-speed rail.
Specifically, in this step, through the latitude and longitude information of the target high-speed rail obtained in step 101 and the position information and height information of the base station in the scene of the target high-speed rail, the position information of the base station closest to the target high-speed rail is screened out, and then the position information of the base station closest to the target high-speed rail is uploaded to the base station edge cloud, wherein the first base station is the base station closest to the target high-speed rail.
For example, the target high-speed rail determines the position distances between itself and N gnbs according to GPS information of N gnbs in its scene pre-stored in the base station edge cloud, screens out the nearest gNB, and then transmits the GPS information of the gNB to the base station edge cloud, where the gNB is the first base station (N is an integer greater than or equal to 1).
Step 103: and acquiring electromagnetic parameter information of the structural body in the target high-speed rail scene.

In some embodiments, for a target high-speed rail in high-speed driving, a three-dimensional scene model of a target high-speed rail scene is constructed through laser point cloud and visual data, structural body surface material information in the three-dimensional scene model is identified through deep learning and visual perception in base station edge cloud by using the three-dimensional scene model of the target high-speed rail scene, then the structural body surface material information in the three-dimensional scene model is mapped to a target frequency band material library which is uploaded to a cloud storage server in advance, and electromagnetic parameter information of a structural body in the target high-speed rail scene is determined.
The scene of the target high-speed rail in the outage state is fixed, so that the electromagnetic parameter information of the structural body in the target high-speed rail scene can be determined directly from a target frequency band material library in the storage server; the method also can be used for constructing a three-dimensional scene model of a target high-speed railway scene through laser point cloud and visual data, identifying the structure surface material information in the three-dimensional scene model through deep learning and visual recognition in the base station edge cloud by using the three-dimensional scene model of the target high-speed railway scene, mapping the structure surface material information in the three-dimensional scene model to a target frequency band material library which is uploaded to a cloud storage server in advance, and determining the electromagnetic parameter information of the structure in the target high-speed railway scene.
Step 104: and determining radio wave propagation angle information based on the position information of the first base station and the electromagnetic parameter information of the structural body in the target high-speed railway scene.
Specifically, the electromagnetic parameters include a dielectric constant of a material surface, a material surface roughness, a decorrelation distance of the material roughness, a scattering index and a scattering coefficient.
In some embodiments, according to the position information of the first base station and the electromagnetic parameter information of the structure in the target high-speed rail scene obtained in the above steps, real-time ray tracing simulation is performed by using a base station edge cloud to obtain accurate radio wave propagation angle information, and then the current direction of the high-gain directional antenna can be adjusted in real time, so that the radio wave propagation angle information is determined by obtaining the position information and the height information of the base station in the high-speed rail scene and the electromagnetic parameter information of the structure in the target high-speed rail scene, a transmission path with the minimum loss is found, and the antenna direction is aligned to the path, thereby realizing stable connection of the 5G wireless communication network.
For example, in aspects of vehicle-mounted and line-along high-definition video monitoring, vehicle-mounted real-time high-data rate communication, train operation information, real-time train scheduling high-definition video, travel information and the like of high-speed rail transportation in the 5G-R era, a stable 5G wireless communication network is needed, so that accurate radio wave propagation angle information can be obtained by acquiring position information and height information of a gNB in a target high-speed rail scene and electromagnetic parameter information of a structure body in the target high-speed rail scene and performing real-time ray tracking simulation by using a base station edge cloud, thereby being capable of controlling an antenna direction, satisfying higher transmission rate and realizing stable connection of the 5G wireless communication network.
