A Collaborative Planning Method for Space-Space-Earth Observation Resources

Abstract

The invention provides a method for collaborative planning of air-space-ground observation resources. The method includes the steps of constructing a heuristic criterion based on task conflicts according to a conflict relation between tasks to be allocated in a set of tasks to be allocated and parameter information of observation resources in a planning center; calculating observation benefits of the observation resources in the planning center from the observation of the tasks to be allocated according to the heuristic criterion; and constructing a task allocation model of the planning center based on the observation benefits. According to the invention, in the collaborative planning of different sub-planning centers, an influence mechanism of the difference among the sub-planning centers and the observation ability of different types of observation resources on the task allocation are considered, so that the collaboration among the different sub-planning centers is deepened, the task observation benefits of the planning center is improved, and the collaborative effect that one plus one is greater than two is obtained in the case of a variety of sub-planning centers.

Description

technical field [0001] The invention relates to the field of space-space-ground integrated earth observation, and more specifically, to a method for collaborative planning of space-space-ground observation resources. Background technique [0002] At present, as the core of the air-space-ground integrated earth observation sensor network, the collaborative planning technology of heterogeneous resources is the main means to transform the emergency disaster task requirements The key to the benefits of sensor network work and to fully tap the potential observation advantages of multi-type observation platforms and multi-sensor systems. The essence of collaborative planning of space-space-earth observation resources is a complex assignment problem. Its goal is to reasonably allocate observation tasks to multiple types of observation platforms on the premise of meeting the observation resource carrying capacity, constraint rules, and task requirements. In order to ensure that obs...

Problems solved by technology

[0005] The planning method based on a single-type observation platform only solves the coordination problem of multiple observation resources of the same type in a single-type observation platform, and obviously cannot meet the needs of collaborative observation among multi-type observation platforms in space, space and ground.

In the collaborative planning of multi-type observation platforms, the advantages of the traditional sequential allocation method can be simple, fast and efficient calculation, without considering the differences of multi-type observation platforms, but the observation capabilities of different types of observation resources in multi-type observation platforms Insufficient consideration of the impact mechanism of task allocation, no in-depth analysis of the conflict relationship caused by constraints on task allocation and the cooperation and competition mechanism of multiple observation platforms, resulting in the inability to cooperate deeply among multiple observation platforms, resulting in the benefit of task observation In the case of paying for multiple types of observation platforms, the synergy effect of one plus one greater than two has not been achieved
