Embodiment 1

[0134] Such as figure 2 As shown, the present invention provides a kind of emergency dispatching method oriented to agile satellite resource, and this method is carried out by computer, and this method comprises:

[0135] S1. Obtain planning information;

[0136] S2. Divide all visible time windows with variable pitch according to the degree of dispersion, and discretize them into multiple visible time windows with fixed pitch;

[0137] S3. Sorting the emergency tasks in the unplanned emergency task set ET according to the degree of urgency from high to low;

[0138] S4. Traverse and select an emergency task from the unplanned emergency task set ET;

[0139] S5. Judging whether the condition for executing the direct insertion strategy of the emergency task is met; if yes, execute the direct insertion strategy of the emergency task, and then execute S10; otherwise, execute S6;

[0140] S6. Judging whether the condition for executing the shift insertion strategy of the emerg...

Embodiment 2

[0230] The present invention also provides an emergency dispatch system oriented to agile satellite resources. The system includes a memory, a processor, and a computer program stored in the memory and operable on the processor. When the processor executes the computer program Steps to implement the method described above.

[0231] It can be understood that the agile satellite resource-oriented emergency dispatch system provided by the embodiment of the present invention corresponds to the above-mentioned agile satellite resource-oriented emergency dispatch method. The corresponding content in the emergency dispatching method, will not be repeated here.

[0232] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0233] ①Designed a variable-pitch visible time window division rule, discretized the pitch angle, discretized the variable-pitch visible time window into multiple fixed-pitch visible time windows, and continuously fi...

Abstract

The invention provides an emergency scheduling method and system for agile satellite resources, and relates to the technical field of emergency task scheduling. By considering the insertion opportunity of the visible time window of the fixed pitch of the ground station in the scheduling algorithm, the appropriate visible time window of the fixed pitch of the ground station is inserted under the condition that the storage constraint of the agile satellite is not met, so that the storage data of the agile satellite is released to the ground station, the imaging data load of the agile satellite is reduced, more task insertion opportunities are provided, and the overall task completion rate is increased. In the algorithm scheduling process, the emergency degree of the emergency task is calculated according to a designed emergency degree heuristic factor of the emergency task, tasks which are large in weight, few in visible time windows of fixed pitching and close to the completion deadline are preferentially arranged, the influence of task arrangement in advance on the insertion opportunity of subsequent tasks is reduced, and the task completion rate and the overall scheme income are improved.

Description

technical field [0001] The invention relates to the technical field of emergency task dispatching, in particular to an emergency dispatching method and system for agile satellite resources. Background technique [0002] As a new generation of three-degree-of-freedom (pitch, roll and yaw) satellites, agile satellites have a longer visible time window and a wider observable range for ground targets, and have physical characteristics that are very suitable for handling emergency tasks. [0003] Due to the high flexibility of agile satellites, it is very suitable for the completion of high-value and high-time-effect urgent tasks. When the existing agile satellites handle emergency tasks, they do not fully consider the urgency of the emergency task, the weight, the length of the visible time window of the fixed pitch, and the impact of the completion deadline on the chance of task insertion. [0004] Existing solutions lead to lower task completion rates and overall program bene...
