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...
