Variable period multi-star emergency task planning method and system with different scheduling mechanisms

Abstract

The invention provides a variable period multi-star emergency task planning method and system with different scheduling mechanisms. The method and system can deal with the complex whole process of theintegration of emergency task planning by combining the fixed period integrated decision planning with the local adjustment planning based on measure and control opportunity. The method and system solves the problem that the uncertainty of emergency task affects the task planning; considering the actual restrictions that the emergency tasks can be observed on the instructions and it can be completed after downloading at the ground station, the emergency task pre-processing scheme is designed and the deadline requirements of the emergency tasks is met. At the same time, considering the earliercompletion of the emergency task, the weight mechanism of the emergency mission time window is designed to ensure that the emergency task is transmitted as soon as possible.

Description

technical field [0001] The invention relates to the field of satellite search, in particular to a variable-period multi-satellite emergency task planning method and system with different scheduling mechanisms. Background technique [0002] Remote sensing satellites use various remote sensors onboard to observe or search for targets on the ground or in the sea. Because remote sensing satellites have the advantages of wide coverage, long duration, and no restrictions on airspace and national boundaries, they play an important role in ocean search and military investigation. [0003] Remote sensing satellites will receive regular tasks and emergency tasks when performing observation tasks. Among them, emergency tasks need to be completed within the deadline and the earlier the completion time, the better. Different from conventional tasks, there are many emergency tasks in the existing technology. However, the prior art does not fully consider that the emergency task needs to ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a variable-period multi-satellite emergency task planning method and system with different scheduling mechanisms, which can combine emergency task planning with fixed-period overall decision-making planning and local adjustment planning based on measurement and control opportunities The whole process of planning integration solves the impact of the uncertain arrival of emergency tasks on task planning; considering the actual constraints that emergency tasks must be marked on the command before they can be observed, and need to be downloaded from the ground station to complete, the emergency task preprocessing plan is designed , and meet the deadline requirements of emergency tasks
