Method and device for measuring antenna direction angle

Abstract

The invention discloses a measuring method and apparatus for the direction angle of an antenna. The method comprises the following steps: determining the direction angle measuring line and direction angle check point of the antenna, wherein the direction angle measuring line is overlapped with or parallel to a plane where an oscillator of the antenna is located, and the direction angle check point of the antenna is not located in the direction angle measuring line; acquiring latitude and longitude information of two measurement points in the direction angle measuring line and acquiring latitude and longitude information of the direction angle check point of the antenna; and in a coordinate system with latitude and longitude as horizontal and vertical coordinates, determining the direction angle of the antenna according to the latitude and longitude information of the two measurement points and the latitude and longitude information of the direction angle checkpoint. The measuring method and apparatus for the direction angle of the antenna measure the direction angle of the antenna on the basis of latitude and longitude, and are high in determination accuracy of the direction angle and in work efficiency, wide in an application scope and not prone to influence by surroundings and geomagnetic variation.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method and device for measuring an antenna direction angle. Background technique [0002] At this stage, mobile communication network construction is in full swing. It is necessary to survey the horizontal direction angle of the base station antenna during the initial network construction or network optimization. If the direction of the base station antenna is not set properly, the network coverage will be affected. Therefore, adjusting the horizontal direction angle of the base station antenna is a network optimization project. A necessary means of optimization. [0003] At present, in order to determine the antenna direction angle, it is usually necessary to use instruments such as a compass to measure the horizontal direction angle of the antenna at the station. When on-site engineering personnel need to obtain the horizontal direction angle of the base station antenna, they ne...

Problems solved by technology

[0004] However, the accuracy of measuring the horizontal direction angle of the base station antenna manually on the station depends on the measurement method of the measurer. Human factors affect the accuracy of the measurement of the antenna direction angle; and the direction angle measured by the compass is easily affected by the surrounding environment and cannot be tolerated Neglect, metal objects in the surrounding environment and strong magnetic equipment such as substations and transformers will affect the accuracy of the measurement angle; moreover, the magnetic north pole of the earth is constantly moving from the bottom right to the top left, and the magnetic pole is the basis for the direction recognition of the compass and compass , the offset of the magnetic pole also has a certain influence on the actual antenna direction angle measurement
