Abstract

The invention discloses a nonlinear algorithm for controlling downtilt angles of an electrically-adjustable antenna, relating to the technical field of base station antenna. Based on a remote control system for the electrically-adjustable antenna, the invention is characterized in that the algorithm set in a controller of the control system comprises the following steps of: 1, storing parameters associated with various modes of the electrically-adjustable antennae which are regarded as controlled objects as well as the number of adjusting rotation of each downtilt angle of various modes of the electrically-adjustable antennae in relation to zero reference; 2, when information of an order for the adjustment of the electrically-adjustable antennae is received, determining, according to the information, the type of the electrically-adjustable antennae to be adjusted and the associated parameters of the controlled electrically-adjustable antennae; and 3, adjusting target downtilt angles of the electrically-adjustable antennae by determining adjusting rotation direction and rotation quantity based on the angle adjusting rotation parameters of the controlled electrically-adjustable antennae and on the current downtilt angle. The algorithm is convenient in use, high in adjustment precision and is suitable for remotely adjusting the electric downtilt angles of various types of the electrically-adjustable antennae in mobile communication.

Description

technical field [0001] The invention relates to the technical field of base station antennas, in particular to a non-linear algorithm for controlling the downtilt angle of an electric adjustable antenna. Background technique [0002] The electric adjustable antenna has the advantages of greatly reducing the operation and maintenance cost of the antenna downtilt angle and improving work efficiency. Therefore, with the continuous maturity of the related technology of the electric adjustable antenna and the construction of the communication network, the use of the electronic adjustable antenna will become more and more extensive. Different types of electrically adjustable antennas with various horizontal beam widths and various gains will also gradually move towards the entire communication network. At the same time, the mechanical mechanism phase shifter used to control the downtilt angle of the electronically adjustable antenna will also vary with the development of various t...
