Alignment method, device and electronic equipment for directional antenna of high-speed rail network

Abstract

The embodiment of the present invention relates to a method, device, electronic device and computer-readable storage medium for aligning a directional antenna in a high-speed rail network. The location information and altitude information of the base station in the target high-speed rail scene, as well as the latitude and longitude information of the target high-speed rail, determine the location information of the first base station, obtain the electromagnetic parameter information of the structure in the target high-speed rail scene, based on the location information of the first base station and the target The electromagnetic parameter information of the structure in the high-speed rail scene determines the angle information of the radio wave propagation. In the embodiment of the present invention, by obtaining the position information and height information of the base station in the high-speed rail scene, and according to the ray tracing simulation technology, the angle information of the radio wave propagation is determined, the transmission path with the least loss is found, and the antenna direction is aligned with the path to realize the wireless network. Stable connection.

Problems solved by technology

[0003] In the existing technical solution, the GSM-R base station uses a unidirectional antenna, and the orientation of the antenna lobe is based on the field strength test plan. According to the experience of the engineer and the testers, the data such as the received signal strength is repeatedly measured along the railway along the railway line. Adjusting the antenna orientation consumes a lot of manpower
