Abstract

The invention discloses an automatic adjusting device and method of satellite antenna polarization. The method comprises: respectively controlling the satellite antenna polarization to rotate to a miuns 90-degree polarization stopper and a 90-degree polarization stopper; respectively outputting a first voltage value corresponding to the mius 90-degree polarization stopper and a second voltage value corresponding to the 90-degree polarization stopper by the sampling end of the polarization stoppers; calculating the polarization coefficient according to the voltage values; controlling the satellite antenna polarization to rotate to a 0-degree polarization stopper; outputting a third voltage value corresponding to the 0-degree polarization stopper by the sampling end of the polarization stopper; according to the third voltage value and the theoretical 0-degree polarization voltage value, calculating a calibration parameter; according to the polarization coefficient and the calibration parameter, calculating to obtain the position of a polarization potentiometer corresponding to the practical polarization angle of satellite antenna; and controlling the polarization potentiometer to rotate the calculation position. The invention improves the polarization adjusting precision and reduces the polarization adjusting time.

Description

technical field [0001] The invention relates to the technical field of satellite antennas, in particular to a satellite antenna polarization automatic adjustment device and method. Background technique [0002] At present, the adjustment of the polarization of the satellite antenna generally adopts the method of on-site manual adjustment. The staff manually calculates the antenna polarization angle according to the geographic latitude and longitude of the working point and the parameters of the working satellite, and then manually rotates the antenna polarization to the calculated antenna. polarization angle and use the meter to make fine adjustments to match the satellite antenna polarization to the satellite signal. This method has the following disadvantages: first, the on-site manual adjustment procedure is complicated, and requires professional operation to complete, which consumes manpower and material resources; second, the adjustment time is long, which affects the o...
