Description

Technical Field

[0001] The invention belongs to the technical field of position marker verification, and relates to a position marker verification method. Background Art

[0002] The position marker is equipped with an antenna (other sensors) and controls its pointing. The working environment is relatively harsh. However, in practice, the inspection personnel are usually too simple in their inspection. Steady-speed tracking is limited to local areas, and the target speed is limited to two, or sometimes even one. Although this is faster, it also has incomplete limitations and may miss possible oscillations of steady-speed tracking. In addition, the positioning function test is placed before the steady-speed tracking test, which in some cases masks the defect that the gyroscope cannot respond in time under low temperature conditions.

[0003] At the same time, no valuable results were found when searching for relevant patents. Summary of the invention

[0004] The technical problems to be solved by the present invention are:

[0005] In order to avoid the shortcomings of the prior art, the present invention provides a method for coordinator verification.

[0006] After a period of practice, in order to solve the problems of the original method, the calibration device verification should follow the following steps:

[0007] (1) After the position marker is powered on, a storage file is set in the control interface to record the subsequent position marker inspection control process. The file name contains the test condition information and the two axes are positioned at their respective center angles;

[0008] (2) Perform steady-speed scanning of the two axes according to the method of detecting whether the position marker is oscillating during steady-speed tracking, and check and eliminate the hidden danger of oscillation;

[0009] (3) Set the movement direction to positive, position the current axis and the other axis at 0°, set the speed to 0° / S, perform a 0° / S steady-speed tracking scan for 1 minute on both axes, measure the zero drift generated during this time, and then reposition to 0°;

[0010] (4) The current axis and the other axis respectively perform the process of positioning the positive symmetric angle, 0°, the negative symmetric angle, and 0° in sequence, and record the positioning accuracy and time during the process;

[0011] (5) The test is completed and the data file is stored.

[0012] The method for detecting whether the position marker steady-speed tracking is oscillating comprises the following steps:

[0013] (1) Place both the azimuth and pitch axes at their negative extreme positions in the direction of the 10% symmetric angle range of their symmetry centers. The azimuth axis steady-speed tracking speed is selected from one of the levels that is increased step by step from the minimum speed to the maximum speed. The frequency is set to the value corresponding to 90% of the motion range evenly divided by the azimuth axis symmetry center at this speed. For a certain speed and frequency selected for the azimuth axis, the pitch axis steady-speed tracking speed is also increased step by step from the minimum speed to the maximum speed. The frequency corresponding to the selected pitch speed is also set to the value corresponding to 90% of the motion range evenly divided by the symmetry center of the pitch axis at this speed. The speed combination of each level of steady-speed tracking of azimuth and pitch shall move at least 3 cycles per axis to complete the steady-speed tracking motion combination of all speed levels of the two axes;

[0014] (2) Position the current axis at the negative limit angle and the other axis at the center of motion;

[0015] (3) Set the speed to 1° / S, and the current axis completes a continuous forward tracking scan at a steady speed of 1° / S from the negative limit angle to the positive limit angle. After completion, the current axis is positioned at the center angle, and the other axis is positioned at the negative limit angle. Then, the axis completes a continuous forward tracking scan at a steady speed of 1° / S from the negative limit angle to the positive limit angle.

[0016] (4) Position the other axis at the negative limit angle and the current axis at the center of motion;

[0017] (5) The speed is set to the maximum speed, and the other axial direction completes continuous positive maximum steady-speed tracking and scanning from the negative limit angle to the positive limit angle. After completion, the other axial direction is positioned at the center angle, and the current axial direction is positioned at the negative limit angle. Then, the axial direction completes continuous positive maximum steady-speed tracking and scanning from the negative limit angle to the positive limit angle.

[0018] (6) Set the movement direction to the reverse direction, position the current axis at the positive limit angle, and position the other axis at the center of movement;

[0019] (7) The current axial direction completes continuous negative maximum steady-speed tracking and scanning from the positive limit angle to the negative limit angle. After completion, the current axial direction is positioned at the center angle, and the other axial direction is positioned at the positive limit angle. Then, the axial direction completes continuous negative maximum steady-speed tracking and scanning from the positive limit angle to the negative limit angle.

[0020] (8) Position the other axial direction at the positive limit angle, and position the current axial direction at the center of motion;

[0021] (9) Set the speed to 1° / S, and the other axis completes a continuous negative 1° / S steady-speed tracking scan from the positive limit angle to the negative limit angle. After completion, the other axis is positioned at the center angle, and the current axis is positioned at the positive limit angle. Then, the axis completes a continuous negative 1° / S steady-speed tracking scan from the positive limit angle to the negative limit angle.
