Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the drawings and specific examples. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0023] A calibration method of horizontal reference mirror, please refer to Figure 1-6 , the instrument and equipment that this method adopts comprises metal horizontal reference plate, horizontal reference mirror, electronic level, autocollimator, reflecting mirror, comprises the following steps:

[0024] S1 statically adjusts the ship equipment 201 and the horizontal reference mirror 103 on the ship body, including the following sub-steps:

[0025] S11 first adjusts the horizontal attitude of the ship's equipment. Specifically, first place the electronic level 101 on the metal horizontal reference plate 102 of the ship, measure the angle value of the trim and heel of the metal horizontal reference plate of the ship, and the...

Abstract

The invention relates to a horizontal reference mirror calibration method. The calibration method comprises the steps: S1, ship equipment and the horizontal reference mirror on a ship body are adjusted in a static state; and S2, calibration is carried out in a dynamic state, and the step comprises the following sub-steps of S21, erecting a first autocollimator above a horizontal reference mirror on a ship body, and conducting alignment, S22, erecting a reflecting mirror between a horizontal reference mirror on the ship body and the first autocollimator, and adjusting the horizontal posture ofthe reflecting mirror to enable the first autocollimator to be aligned with the reflecting mirror, S23, erecting a second autocollimator above the horizontal reference mirror and the reflecting mirroron the ship equipment, and adjusting the second autocollimator to enable the second autocollimator to be aligned with the reflecting mirror, and S24, removing the reflecting mirror, and reading the numerical value displayed by the second autocollimator, the numerical value being the difference value between the horizontal reference mirror of the ship equipment and the horizontal reference mirrorof the ship body. Thus, the horizontal attitude of the ship equipment can be accurately remeasured in a dynamic state.

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 horizontal calibration method of the attitude of ship equipment under conventional conditions is to use an electronic level. First, place the electronic level on the metal horizontal reference plate of the ship, measure the angle value of the pitch and heel of the metal horizontal reference plate of the ship, and then put the electronic level Place it on the horizontal datum plane of the ship equipment, and measure the angle value of the trim and heel of the horizontal datum plane of the ship equipment. Such as figure 1 shown. However, the measurement of the horizontal attitude of ship equipment under dynamic conditions is affected by the ship's inclination angle, swing amplitude and swing period, and the measurement accuracy of the electronic level w...
