Antenna remote adjusting system and adjusting method thereof

Abstract

The invention provides an antenna remote adjusting system and an adjusting method thereof. An antenna electronic downward inclination angle adjusting assembly comprises a phase shifter transmission ruler; the sliding block is connected with the phase shifter transmission ruler; the control unit is provided with a motor and a control circuit; the screw rod is parallel to the axis direction of the phase shifter transmission ruler, the sliding block is in threaded connection with the screw rod, the motor drives the screw rod, and the sliding block drives the phase shifter transmission ruler to move in the axis direction of the screw rod along with rotation of the screw rod; and the sliding resistor is used for detecting the resistance value of the phase shifter transmission ruler at the current position based on the movement stroke setting of the phase shifter transmission ruler and sending the resistance value to the control circuit, and the control circuit obtains the current electronic downward inclination angle at least according to the resistance value. According to the invention, more motors can be replaced without calibration, closed-loop control is realized by matching the sliding resistor in the antenna with the resistor, the internal structure of the remote control unit is reduced, the structure of the existing electrically-tunable antenna remote control unit is simplified, and the overall volume is reduced.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to an antenna remote adjustment system and an adjustment method thereof. Background technique [0002] By adjusting the downtilt angle of the antenna, the network coverage can be effectively enhanced and optimized. Although mechanical adjustment of downtilt angle can improve coverage to a certain extent, there are disadvantages such as the mechanical adjustment method consumes too much manpower and material resources, cannot be adjusted and optimized in real time, and the downtilt angle adjustment range is limited. Compared with the mechanical downtilt antenna, the electronically adjustable downtilt antenna can effectively enhance the radial coverage of the cell, and at the same time reduce the interference to the neighboring cells of the same station, so as to solve the problems of over coverage, too large or too small soft handover area, and Problems such as call drop, capa...

AI Technical Summary

Problems solved by technology

[0003] At present, after the remote control unit (RCU) is replaced, the electronic downtilt angle of the antenna needs to be recalibrated to adjust.

The calibration time takes a long time; the power source is a stepper motor, and other types of motors cannot be replaced. The speed of the stepper motor is low, and the electronic downtilt angle adjustment speed is slow; The magnet reads the angle, occupies the volume of the remote control unit (RCU), and must be replaced as a whole when replacing the remote control unit (RCU)
