Embodiment approach

[0029] The locking actuator is generally in the shape of a ring, and its outer diameter is larger than that of the docking ring of the target satellite. The docking structure is connected with the service satellite body through a mounting bracket. The mounting bracket is connected to the base component, and the transmission component moves on the base component to drive the action of the holding component and the locking component to complete the hugging, pressing down, locking and releasing of the docking ring of the target satellite. The spring damper generates a pre-tightening force during the docking and locking process. When releasing and separating, the target satellite docking ring is ejected under the action of the pre-tightening force to realize the separation from the target satellite. There are three photoelectric sensors, which are evenly distributed on the circular base of the locking actuator, with an included angle of 120 degrees. There are three inductive sens...

Abstract

The invention discloses a satellite docking and locking automatic control method and system. According to the control method, a motor is adopted by a locking executing mechanism for providing power, and the locking executing mechanism comprises an enclasping assembly mounted on a base and used for achieving the enclasping and downwards pressing functions on a docking ring of a target satellite, a locking assembly used for achieving locking with the docking ring of the target satellite and a damping mechanism used for reducing rigid impact when the locking executing mechanism makes contact with the target satellite. According to the satellite docking and locking automatic control method and system, closed loop full-automatic control over the satellite docking and locking process can be achieved, actions of enclasping, downwards pressing and locking of the locking mechanism to the docking ring of the target satellite can be completed automatically and accurately without human participation, the locking process and state can be automatically monitored in real time in the whole process, and the automation degree and reliability of locking of the satellite docking ring are greatly improved.

Description

technical field [0001] The invention relates to an automatic control method and system for docking and locking, in particular to an automatic control method and system for docking and locking of satellites. Background technique [0002] Restricted by multiple factors such as the life of satellite components, fuel, carrying capacity, launch and in-orbit operating environment, the satellite is in the full life span from launch into orbit, orbit transfer, initial orbit deployment, planned operation, extended operation, and end of operation. During the process, on-orbit failures are inevitable. According to NASA's 2010 statistics on satellites currently in orbit and in the future, it is estimated that by 2022, there will be about 203 GEO satellites in orbit that will need refueling, including 150 commercial satellites and 53 military satellites. ESA’s analysis of GEO satellite statistical data points out that, on average, one GEO spacecraft needs to be transferred from a wrong ...
