Abstract

The invention discloses an antenna downtilt angle automatic adjustment method and system based on unmanned aerial vehicle vision measurement. The method comprises: an unmanned aerial vehicle shooting an antenna real-time image and sending the image to an upper computer, then the upper computer processing the antenna real-time image through a trained instance segmentation network model to obtain an antenna mask, and the upper computer calculating by using a least square method according to the antenna mask to obtain a real-time antenna downtilt angle and further obtain an adjustment signal; and finally, sending an adjustment signal to the antenna to automatically adjust the downtilt angle of the antenna. Through the cooperation of the antenna, the unmanned aerial vehicle and the upper computer, the downtilt angle of the antenna is automatically shot, calculated and adjusted, and the method has the characteristics of high automation and intelligence, and is convenient and fast. Manual tower climbing is not needed in the whole process, potential safety hazards caused by tower climbing are avoided, and time and labor are saved.

Description

technical field [0001] The invention relates to the field of communication measurement, in particular to an automatic adjustment system for antenna downtilt angle based on unmanned aerial vehicle vision measurement. Background technique [0002] A mobile communication base station is a form of radio station, usually equipped with an antenna for transmitting signals. The downtilt angle of the antenna of the mobile communication base station needs to be adjusted according to the actual conditions such as network coverage requirements, traffic volume, anti-interference ability, terrain and network service quality. With the increasing popularity of electronic products such as mobile phones and tablets, in order to meet the needs of the public, the number of mobile communication base stations is increasing, and the frequency of antenna downtilt adjustment is increasing. The traditional mobile communication base station adjustment method is to obtain the antenna downtilt angle by...
