Embodiment Construction

[0040] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041]Since the air-space collaborative task planning problem has the characteristics of related NP-Hard problems, in order to concentrate on the research on the main issues and determine the boundaries of the research problems, so as to ensure a reasonable collaborative task planning, this paper puts forward relevant assumptions to simplify the model:

[0042] (1) The satellite is equipped with visible light load, and has three-axis attitude maneuverability of side swing, pitch, and yaw;

[0043] (2) The sate...

Abstract

The invention provides an air-space collaborative observation complex task scheduling method and system, and the method comprises the steps: dividing a search region according to grids, dividing a complex task into sub-task sets according to the grids covered by the task, and distributing the sub-task sets to all platforms according to a task planning frame of distribution-planning-adjustment-distribution. Each platform performs task planning, then a planning result is adjusted according to a heuristic rule to obtain a planning scheme of the allocation, an allocation scheme is reformed according to the obtained planning scheme, loop iteration is performed, and finally a satisfactory allocation scheme is found. According to the method, the multi-layer nested genetic algorithm is designed, so that the planning problem of the air-space collaborative observation complex task can be efficiently and flexibly solved, and the planning speed and the planning quality of the method are far higher than those of a traditional planning method for the air-space collaborative observation complex task.

Description

technical field [0001] The invention belongs to the field of mission planning and dispatching, and in particular relates to a method and system for dispatching complex missions of space-space collaborative observation. Background technique [0002] Complex tasks mainly refer to the collection of all different types of tasks issued by users within a certain period of time, collectively referred to as complex tasks, and perform unified preprocessing, planning, coordination, and execution observation on complex tasks, as shown in Table 1. The complex task planning problem of space-space collaborative observation refers to the use of satellite and UAV observation resources, according to the load characteristics, maneuverability, operation mode, etc. of satellite and UAV observation platforms, to process complex tasks through related methods of collaborative planning, The planning goal is to reasonably allocate observation resources, determine the execution time of each task, and...
