Time redundancy heuristic planning method, device and equipment for space station operation tasks

Abstract

The invention relates to a time redundancy heuristic planning method, device and equipment for space station operation tasks. The method comprises the following steps: collecting scene information of space station short-term task planning; constructing a task time sequence chain according to the time constraint, the logic constraint and the execution starting time initial value sequence of the event to be planned in the scene information; obtaining an event initial planning sequence according to a to-be-planned event execution time initial value sequence, and carrying out conflict solution adjustment on to-be-processed events at the same position in a plurality of task time sequence chains according to conflict conditions among the events to obtain an event execution time sequence and a to-be-cut event sequence; and inserting the to-be-clipped events meeting the conditions into the event execution time sequence to obtain a final event execution time sequence and a clipped event sequence, and outputting the final event execution time sequence and the clipped event sequence. By adopting the method, a high-quality planning scheme for the space station operation task planning problem can be quickly solved in a very short time at very low calculation cost, and the practical engineering application can be met.

Description

technical field [0001] The present application relates to the technical field of space station orbit operation task planning, in particular to a time redundancy heuristic planning method, device and equipment for space station operation tasks. Background technique [0002] my country will build a low-Earth orbit space station with a three-cabin configuration and a mass scale of about 60 tons around 2022. As a base for human beings to live and work for a long time and an important guarantee for human beings to explore deep space, the operation of the space station will involve the flight orbit plan, astronaut on-orbit residence and rotation plan, large-scale payload application plan, and cargo spacecraft supply plan and other complex on-orbit tasks. In order to ensure the long-term continuous operation management of the space station and the effective development of space missions, it is necessary to plan the space station orbit missions within a certain period of time befor...

AI Technical Summary

Problems solved by technology

In the short-term mission planning of the space station, if the constraint relationship between events is not considered, the mission planning scheme will be unreasonable, resulting in waste of resources, which is not suitable for actual engineering needs
