Problems solved by technology

However, this adjustment method does not take into account the stability of the transmission system. When there is a mechanical tolerance or even a mechanical failure in the transmission system or a mechanical deformation of the transmission rod, the movement of the transmission block may deviate, resulting in a deviation in the actual adjusted downtilt angle. Inconsistent with the required adjustment of the downtilt angle, resulting in a deviation in the adjustment accuracy of the downtilt angle

Abstract

The embodiment of the invention discloses a device for adjusting a downdip angle of a communication antenna. The device comprises an electronic downdip angle control unit, a driving unit, a driving shaft and a limiting mechanism. The driving unit is provided with a control input terminal and a power output terminal, wherein the control input terminal is connected with the electronic downdip angle control unit, and the power output terminal is coupled with the driving shaft. One end of the driving shaft is coupled with a power output terminal of the driving unit and driven by the driving unit to move in an axial direction, so as to adjust the downdip angle of the communication antenna. The limiting mechanism mechanically blocks the driving shaft, so that the driving shaft can move within a pre-determined range. The device disclosed by the embodiment of the invention can effectively control the adjustment accuracy of the downdip angle of the communication antenna.

Description

technical field [0001] The invention relates to the technical field of communication antennas, in particular to a device for adjusting the downtilt angle of a communication antenna. Background technique [0002] In the mobile communication system, in order to realize the coverage optimization of the wireless signal of the serving cell and to suppress the same-frequency interference between the same-frequency cells, it is necessary to reasonably adjust the downtilt angle of the base station communication antenna to make the vertical pattern of the antenna downtilt. The downtilt angle of the antenna determines the coverage area of ​​the antenna beam. [0003] In the prior art, the way to adjust the downtilt angle of the antenna is to control the transmission system to rotate the transmission rod, the transmission block on the transmission rod moves axially, and the downtilt angle of the communication antenna is adjusted through the movement of the transmission block. However,...
