Abstract

The invention discloses an electric tuning control system, an electric tuning control device and an electric tuning control method of a multi-frequency antenna. The electric tuning control method of the multi-frequency antenna comprises the steps: an angle adjustment instruction is received, and whether a current gear is a target gear or not is judged; if the current gear is not the target gear, apower device starting instruction is sent, the rotating power output shaft of the power device is enabled to rotate in the first rotating direction and the current gear is adjusted to the target gear; and after the current gear is adjusted to the target gear, the rotating power output shaft of the power device is enabled to rotate by a preset number of turns in the direction opposite to the firstrotating direction. The antenna downward inclination angle of multiple frequency bands can be adjusted through one power device based on the electric tuning control method, the cost of the electric tuning control system can be reduced and miniaturization development of the antennas is facilitated.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to an electrical regulation control system, an electrical regulation control device and an electrical regulation control method for a multi-frequency antenna. Background technique [0002] At present, the electric downtilt adjustment of the base station electric antenna is usually realized by the rotation of the power device to drive the movement of the antenna phase shifter. In the current design of the electric control system, one power unit corresponds to adjust the phase shifter of one antenna frequency band, and antennas with multiple frequency bands need to use multiple power units. [0003] With the widespread use of multi-frequency electric-tunable antennas, if each antenna frequency band needs to use a power device to adjust, the cost of the multi-frequency antenna electric-tuning control system will become higher and higher, and the volume will also become larger ...
