Leveling control system and method for rocket launching platform

Abstract

The invention discloses a leveling control system and method for a rocket launching platform. The leveling control system of the rocket launching platform comprises: a first detector arranged on a movable supporting leg of the rocket launching platform and used for feeding back the length of the movable supporting leg; a second detector used for detecting a first inclination angle of the rocket launching platform relative to the first shaft and a second inclination angle of the rocket launching platform relative to the second shaft; and a control module used for calculating the distance needing to be adjusted of the movable supporting leg by utilizing the first inclination angle and the second inclination angle and controlling the movable supporting leg to be adjusted until the platform meets the precision requirement. By means of the leveling control system of the rocket launching platform, leveling of the launching platform can be rapidly and accurately completed, the second detectoris used for judging the inclination angles in the two axial directions, the control module calculates the distance needing to be adjusted of each movable supporting leg, the corresponding distance isadjusted through the first detector, the control module controls the movable supporting legs to be leveled, and the first detector enables the leveling process to be faster and more accurate.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a leveling control system and method for a rocket launch platform where a launch vehicle or special equipment requires a precise leveling environment. Background technique [0002] With the rapid development of my country's aerospace industry, the "three-level" test-launch mode has gradually appeared in the test-launch mode of the launch vehicle. The "three-level" test-launch mode puts forward high requirements on the leveling accuracy and time of the launch pad. [0003] This is reflected in two aspects: [0004] First: The traditional one-level two-vertical (horizontal transfer, vertical assembly, and vertical test) and three-vertical (vertical transfer, vertical assembly, and vertical test) mode launch towers are far away from the rocket, and the rocket connector protrudes through the launch tower. The swing arm is connected to the rocket, and the rocket connector a...

Problems solved by technology

[0004] First: The traditional one-level two-vertical (horizontal transfer, vertical assembly, and vertical test) and three-vertical (vertical transfer, vertical assembly, and vertical test) mode launch towers are far away from the rocket, and the rocket connector protrudes through the launch tower. The swing arm is connected to the rocket, and the rocket connector also adopts the mode of falling off in advance. The error of the level of the launch platform will not cause a safety risk to the launch process; After the ignition, the vertical arm is quickly reversed to give way to the rocket take-off drift. If the leveling accuracy error is too large, the rocket may hit the vertical arm during take-off, resulting in a major flight accident in which the arrow is destroyed;

[0005] Second: The leveling process of the traditional one-level, two-down and three-down modes is gradually completed during the rocket assembly process, and the leveling process has little impact on the launch process time; the launch pad leveling process under the three-level mode is included in the launch process, The leveling process of the launch pad directly affects the length of the launch process. If the leveling process is too long or the leveling process is unreliable, it will directly lead to the delay or even cancellation of the launch, and will also cause major economic losses.
