Abstract

Embodiments of the present invention provide a method, a device, an electronic device, and a storage medium for determining an azimuth. The method includes determining a position angle according to the position information of the sampling point and the position information of the base station corresponding to the sampling point, and the position angle is based on the base station as the vertex and the north direction as the starting side, and rotates clockwise The angle to the sampling point; obtain the relative AOA of the sampling point, the relative AOA is based on the normal of the antenna as the starting side, and rotates clockwise to the angle of the sampling point, and the relative AOA is based on the true north direction The standard AOA of the true north direction is obtained by the base station according to the azimuth angle of the industrial parameter, with the true north direction as the starting side, and the angle rotated counterclockwise to the sampling point; according to the position angle and the relative AOA, to determine the azimuth of the antenna. The method guarantees the accuracy of the relative AOA by obtaining the relative AOA which has nothing to do with the azimuth of the industrial parameter, thereby improving the accuracy of the output actual azimuth.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, in particular to a method, device, electronic device and storage medium for determining an azimuth angle. Background technique [0002] The transmission and reception of signals in mobile communication networks need to rely on antennas. Especially in cellular mobile communication networks, base stations mainly use directional antennas to cover specific areas. Overall performance plays a vital role. [0003] There are many methods for measuring the azimuth angle in the prior art, and generally speaking, there are mainly the following methods: [0004] Method 1. The information collection personnel go to the antenna installation site and use the compass to measure the azimuth and record it; [0005] Method 2, hardware telemetry method, install a dedicated remote measurement device on the base station antenna, and transmit the measurement information of the azimuth ...

AI Technical Summary

Problems solved by technology

[0010] The first method is the traditional method, which is also the most widely used antenna azimuth acquisition method at present. The obvious problem is that it needs to consume a lot of manpower, material resources and time, and the efficiency is not high. At the same time, the update speed is slow, such as wind, third-party construction Influence and other situations cannot be discovered in time when the antenna azimuth angle changes, which will affect the output of network evaluation and network optimization schemes;

[0011] The results collected by the second method are more accurate and updated in a timely manner. However, it is necessary to purchase supporting software and hardware platforms and maintenance services. During deployment, it is necessary to install measurement devices on each antenna and deploy a wireless receiving platform at the same time. The large amount of engineering and high cost hinder this method. Popularity, the current application area is less;

[0012] Method 3 Calculate the radiation gain of the antenna according to the level strength of the sampling point, and then determine the antenna azimuth angle according to the radiation gain envelope. This method is clear in thinking, but the environment in the actual network is complex and diverse, and the signal propagation is not a simple line of sight. Transmission, a large number of refraction and reflection all have a significant impact on the results of its radiation gain, and the signal penetration loss is more closely related to the sheltered building materials, so the error of the final result is too large;

[0013] Method 4 is mainly calculated based on the AOA in the measurement report, but AOA itself is a result of the calculation of the azimuth angle of the existing engineering parameters. If there is a problem with the azimuth angle of the existing engineering parameters, the AOA itself is not accurate enough; at the same time The accuracy of AOA can only be guaranteed under straight-line line-of-sight propagation. Many paths after signal refraction and reflection in the actual network are no longer the paths represented by the simple straight-line connection between sampling points and antennas, so the error will further increase

[0014] At present, there is no corresponding method in the existing technology that can efficiently, economically and accurately determine the azimuth angle
