An electrical adjustment method and device for a base station antenna

Abstract

The invention discloses a method and equipment for electrical tuning of a base station antenna, in order to reduce the probability of occurrence of electrical tuning abnormality of the base station antenna, wherein the method comprises the steps of: determining a stroke error of a motor on a stroke rod, wherein the stroke error is a difference value between an ideal stroke of the motor on the stroke rod and an actual stroke of the motor on the stroke rod; comparing the stroke error with a preset abnormality threshold, wherein the preset abnormality threshold is an abnormality threshold matchedwith a current speed at which the motor runs, when the stroke error is greater than the preset abnormality threshold, it is indicated that electrical tuning abnormality occurs on the base station antenna, the electrical tuning abnormality comprises stalling of the motor; if it is determined that the stroke error is greater than the preset abnormality threshold, judging whether abnormal stalling occurs on the motor; and if it is determined that the abnormal stalling occurs on the motor, outputting alarm information, wherein the alarm information is used for indicating that the abnormal stalling occurs on the motor.

Description

technical field [0001] The present invention relates to the technical field of base station antennas, in particular to a method and equipment for electric adjustment of base station antennas. Background technique [0002] The downtilt angle of the base station electronically adjustable antenna is a very important technical parameter in the antenna work. Parameters such as the angle, strength and area of ​​mobile signal coverage will change with the change of the downtilt angle of the antenna. Usually, the downtilt angle of the antenna needs to be adjusted according to the actual working scene of the antenna. Adjusting the downtilt angle of the antenna is actually achieved by controlling the motor to drive the phase shifter of the antenna to move from the initial position to the target position. The motor may have abnormal conditions during its operation. One situation is that the motor is abnormally locked. When the motor moves the phase shifter from the current position to...

Problems solved by technology

If motor vibration is given priority, and the motor is running under low-speed and high-torque conditions, it is expected that the preset threshold of the blocking judgment condition should be as small as possible, but for abnormal stalls, it is easier to meet the smaller preset threshold blocking judgment condition. As a result, misjudgment occurs, causing the motor to stop by mistake.

On the contrary, if the priority is given to abnormal stalling, and the motor is running under high-speed and low-torque conditions, it is expected that the preset threshold value of the blocking judgment condition should be set as large as possible, but for motor vibration, it is difficult to meet the larger preset threshold threshold judgment condition , causing the motor to not stop even if the motor shakes

[0004] It can be seen that when the existing technology solves the abnormality of the antenna ESC, it either fails to stop the motor in time, or causes the motor to stop by mistake, and the probability of abnormality of the base station antenna ESC is high
