Abstract

The invention relates to a zero calibration method for an adjusting device for an antenna panel, which can solve the technical problem of low adjustment precision of the adjusting device caused by improper zero calibration way, and the adopted technical scheme is as follows: the zero calibration method is realized during the process of using the adjusting device to adjust the position of the antenna panel, the adjustment process can drive a lifting mechanism with the help of a stepping motor and a power transmission mechanism arranged on a main framework, a controller and matching software procedure, a support frame of the antenna panel arranged on the lifting mechanism can realize position adjustment of the lifting with the help of the lifting mechanism, a grating ruler with a grating groove, a first groove type optocoupler, a code wheel with the grating groove and a second groove type optocoupler are further arranged in the adjusting device, wherein the grating ruler and the first groove type optocoupler are arranged on the support frame, and the code wheel and the second groove type optocoupler are coaxial with a rotating shaft of the stepping motor, and initial zero adjustment and precise zero adjustment are carried out under the conditions. The key of the zero calibration method is that a zero adjustment mechanism is increased in the adjusting device, thereby achieving the purpose of precisely adjusting zero position and improving the adjustment precision of the adjusting device.

Description

technical field [0001] The invention relates to a zero calibration method of an adjustment device used for an antenna panel, which belongs to the technical field of adjustment, in particular to a zero calibration method for realizing automatic zero calibration by means of an adjustment process. Background technique [0002] Antennas are mainly used to effectively directional reflect and receive electromagnetic waves, and are part of electronic equipment such as radar and communication. Surface antenna is a main type of antenna, including various parabolic antennas, fan-shaped beam antennas, double reflector antennas, spherical antennas, etc. [0003] In the design of large-scale high-precision antenna systems, the surface accuracy of the antenna reflector is one of the main technical performance indicators of the antenna, which directly affects the electrical performance such as antenna gain. With the increase of the antenna diameter and the increase of the operating freque...
