Problems solved by technology

The existing technical solutions have the following disadvantages: 1). The types of constraints that can be processed are limited, which cannot meet the requirements of single-satellite multi-load complex constraint mission planning; 2). The way to process constraints is single; 3). Since the constraints are preset in the software In the process, it is impossible to perform customized processing according to the constraints of different aircraft and different loads at runtime. Therefore, the constraint processing function is not universal

Embodiment Construction

[0044] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0045] figure 1 It is a software system architecture diagram of processing constraint types in the prior art.

[0046] like figure 1 As shown, the prior art solution divides the software system into three parts: input information management, task solution management, and output information management.

[0047] The input information management part includes three functional modules of file operation, constraint processing and network structure. The task solution management part includes four functional modules: solution framework, sorting, observation activity arrangement and return activity arrangement. The output information management part includes two functional modules of intermediate result management and fi...

Abstract

The invention relates to a method and system for planning single-satellite multi-load complex constraint task. The method comprises the steps of sorting pre-processed user tasks to obtain an intermediate plan queue; detecting whether there are conflicts between the tasks in the intermediate plan queue or not, if so, extracting the conflicts, and sorting the conflicts from high to low according tothe constraint priority so as to form a conflict queue; and eliminating the conflicts selected from the conflict queue, adding the tasks after the eliminating processing to the current intermediate task queue until there is no conflict between the tasks in the intermediate plan queue, and outputting the intermediate plan queue. The method and system for planning the single-satellite multi-load complex constraint task have universality for constraint processing for different types of loads.

Description

technical field [0001] The invention relates to the field of spacecraft mission planning, in particular to a single-satellite multi-load complex constraint mission planning method and system. Background technique [0002] Spacecraft mission planning mainly solves the problem of optimal arrangement of space observation tasks and space application tasks, which belongs to the category of artificial intelligence and operations research. Currently, research in this field is mainly focused on mission planning for imaging satellites, and the research goal is to maximize the benefits of observation missions. [0003] With the gradual deepening of space applications, the future spacecraft will develop towards miniaturization and distributed networking on the one hand; on the other hand, it will develop towards large-scale and highly integrated. For the latter, it is bound to carry more payloads to perform tasks. Multiple payloads working together in orbit put forward higher require...
