Multi-satellite situation awareness system distributed task planning method based on a contract net

Abstract

The invention provides a multi-satellite situation awareness system distributed task planning method based on a contract net. The contract net comprises a global planning layer, an emergency planning layer and a local planning layer. The method comprises the following steps: step 1, a global supervisory satellite assigns a local supervisory satellite; 2, the global supervisory satellite carries out bidding on the sensing task, and the local supervisory satellite carries out task bidding; 3, after the global supervisor satellite receives the bidding result, matching between the sensing target cluster and the satellite cluster is carried out; 4, the local supervisor satellite carries out bidding on the sensing task, and the subordinate satellite carries out bidding; 5, after the local supervisor satellite receives the bidding result, the local perception target is distributed to the local satellite; 6, when an emergency task occurs, the emergency task supervisor satellite allocates the emergency task to each local planning layer; and 7, the local planning layer allocates the task to a satellite executing the task; According to the method, the problem of task allocation with multiple satellites, multiple tasks and multiple burstiness can be solved.

Description

technical field [0001] The invention relates to the technical field of satellite situational awareness, in particular to a distributed task planning method for a multi-satellite situational awareness system based on a contract network. Background technique [0002] With the continuous development and growth of aerospace technology in various countries, space resources have become the most valuable strategic resources in the military field. Space situational awareness is to realize the tracking and measurement of space targets, the monitoring of the entire space state and form, and the visual detection of stranded space targets through various monitoring methods, providing decision-making basis for space operations and defense, and is the primary condition for maintaining space superiority. is the basis for all space operations. Strong space situational awareness is the core capability of space security, space resources development and ensuring national security. [0003] S...
