A device and method for adjusting electric downward inclination angle of an electric tuning antenna

Abstract

The invention belongs to the technical field of communication and discloses a device and method for adjusting the electric downward inclination angle of an electrically tunable antenna. An electric tuning controller is respectively connected with an induction coil plate and a motor, the induction coil plate is fixed on a screw rod, the motor is connected with a slider, the metal plate is fixed ona slider, the slider is engaged with the screw rod, and the two ends of a driving rod are respectively connected with a slider and a phase shifter. The electric tuning control controller receives thecontrol information from a network management platform. The electric tuning controller obtains the first inductance information by reading an induction coil board. Obtaining slider position information according to the first inductance information; According to the control information and the position information of the slider, the driving information of the motor is calculated. According to the driving information, the motor is controlled to drive the slider to make linear translation motion on the screw rod through the rotation of the motor, and the slider drives the phase shifter to make synchronous linear translation motion through the transmission pull rod. The invention can improve the success rate of the remote electric tuning of the electric tuning antenna and reduce the maintenance cost of the electric tuning antenna.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an electrical downtilt adjustment device and method for an electrically adjustable antenna. Background technique [0002] With the rapid development of the communication industry, operators and users have continuously improved requirements for network quality, especially in dense urban areas and areas with high floors, network optimization and adjustment are frequent, and the electrical downtilt angle of base station antennas often needs to be adjusted. The electrical adjustable antenna can conveniently adjust the electrical downtilt angle of the antenna, and has been widely used in the field of mobile communication. [0003] The electrical downtilt of the electric adjustable antenna is adjusted by a phase shifter, and the adjustable phase shifter is driven to move or rotate through a mechanical device, thereby changing the electrical length of the feed network to adjust t...

Problems solved by technology

[0005] However, in the process of electric adjustment, it is necessary to calibrate before adjusting the angle, that is, to find the reference point of the electric downtilt angle. In the process of finding the reference point, due to problems such as antenna technology, screw quality, and motor encoder, it often leads to If the calibration is not successful, maintenance personnel need to troubleshoot the problem on site, which is time-consuming and laborious, which greatly increases the maintenance cost of the antenna
