Abstract

The invention relates to a calibration method of a horizontal reference mirror, the steps are: S1 adjust the ship equipment and the horizontal reference mirror on the ship body under static conditions; S2 perform calibration under dynamic conditions, including the following sub-steps: S21 on the ship Set up the first autocollimator above the horizontal reference mirror on the main body and align it; S22 set up a reflector between the horizontal reference mirror on the ship body and the first autocollimator, and adjust the horizontal attitude of the reflector so that the first autocollimator An autocollimator aligns the reflector; S23 erects a second autocollimator above the horizontal reference mirror and the reflector on the ship equipment, adjusts the second autocollimator to align the second autocollimator Reflector; S24 Remove the reflector, read the value displayed by the second autocollimator, this value is the difference between the horizontal reference mirror of the ship equipment and the horizontal reference mirror of the ship body. The invention realizes accurate retesting of the horizontal attitude of ship equipment under dynamic conditions.

Description

technical field [0001] The invention belongs to the technical field of attitude calibration of ship equipment, and specifically designs a calibration method for a horizontal reference mirror. Background technique [0002] The conventional method of level calibration of the attitude of the ship equipment is to use an electronic level, first place the electronic level on the ship's metal horizontal reference plate, measure the angle value of the trim and heel of the ship's metal horizontal reference plate, and then place the electronic level on the ship's metal horizontal reference plate. It is placed on the horizontal datum plane of the ship equipment, and the angle value of the trim and heel of the horizontal datum plane of the ship equipment is measured. like figure 1 shown. However, the measurement of the horizontal attitude of the ship equipment under dynamic conditions is affected by the ship's inclination angle, swing amplitude and swing period, and the measurement ac...
