Method and system for measuring downward inclination angle of base station antenna as well as devices

Abstract

The invention discloses a method and a system for measuring the downward inclination angle of a base station antenna as well as devices. The method comprises steps as follows: an unmanned aerial vehicle measurement device hovers on the side surface of the base station antenna according to a flight control instruction of a ground control device; the unmanned aerial vehicle measurement device acquires a real-time image of the base station antenna and returns the image to the ground control device, so that the ground control device recognizes predetermined measurement points; the unmanned aerialvehicle measurement device sequentially measures the distance between a hovering point of an unmanned aerial vehicle and each predetermined measurement point according to a measurement control instruction of the ground control device and records the angle when a cloud deck rotates to each predetermined measurement point via an electronic cloud deck module; the unmanned aerial vehicle measurement device returns measurement data to the ground control device, so that the ground control device obtains the downward inclination angle of the base station antenna according to measurement data. Compared with the prior art, the method and system as well as the devices have the advantages that a measurement worker does not need to climb a base station iron tower to conduct measurement operation, accordingly, the working efficiency is improved, and the risk of climbing operation is reduced.

Description

technical field [0001] The invention relates to the field of mobile communications, in particular to a method, device and system for measuring downtilt angles of base station antennas. Background technique [0002] With the rapid development of mobile communication technology, communication operators deploy a large number of mobile communication base stations in order to better develop mobile communication services. Base station antenna downtilt is an important parameter that has a great influence on signal coverage. On the one hand, the accurate downtilt angle can ensure that the actual coverage of the base station is the same as expected. On the other hand, according to network problems such as network interference and traffic, adjusting the downtilt angle of the base station can better optimize the current coverage. There is a network to improve user service perception. [0003] The downtilt angle of the base station antenna includes the electronic downtilt angle and th...

Problems solved by technology

[0006] (3) The mechanical connection parts of the antenna are rusted, corroded, etc.

Due to the huge number of base stations, this work requires a lot of manpower and material resources

This manual measurement method has limitations in the following aspects: First, accurate measurement of the mechanical downtilt requires climbing work, which is risky; second, the hand-held slope meter is used for testing, and the accuracy is not high due to manual shaking and visual inspection; the second measurement needs to arrive at the base station site For testing, the real-time performance is limited, and the time cost and labor cost are high; finally, the base station is installed upstairs on the owner's floor, and manual on-site measurement will receive interference from the owner, which is not conducive to maintaining the relationship between the communication operator and the owner
