Problems solved by technology

In this scheduling method, the task conflict judgment execution process is long, and the optimal scheduling table cannot be obtained quickly.
At the same time, the execution task and the constraint release task are not scheduled at the same time during the entire scheduling process, which cannot effectively eliminate conflicts

Embodiment 1

[0028] Such as figure 2 As shown, the present invention provides a satellite resource cross-domain coordinated scheduling system, which at least includes an optimization management module 1 , an execution management module 2 , a monitoring management module 3 and a demand processing module 4 . The optimization management module 1 can analyze different variables for scheduling satellites to simulate the actual operation behavior of satellites and optimize and adjust the schedule for scheduling satellites 5 and ground stations 6 according to satellite feedback data. Scheduling the satellite 5 and the ground station 6 through the optimized and adjusted schedule can obtain better satellite resource utilization efficiency. The optimization management module can dynamically modify the schedule in response to new tasks, unexpected events or satellite performance changes. The entire optimization and adjustment process can be carried out without human intervention, and it can take int...

Embodiment 2

[0041] This embodiment is a further improvement on Embodiment 1, and repeated content will not be repeated here.

[0042]Preferably, the satellite coordinated dispatching system further includes a control command generation module 7 . The control command generation module is configured to be able to generate a first control command set according to the action tasks of the satellites and / or ground stations, and the first control command set includes a list of action tasks of several satellites and / or ground stations. The control command can be displayed in a binary manner to indicate its status, for example, when its value is "1", it means "execute action task", and when its value is "0", it means "skip action task". Control commands can be used to describe the problem to be solved and the user controls the execution or non-execution of other tasks associated with the motion task. For example, when a satellite is performing an imaging task, the control command can instruct the...

Embodiment 3

[0063] This embodiment is a further improvement on the foregoing embodiments, and repeated content will not be repeated here.

[0064] Preferably, the optimization management module 1 is also configured to optimize and adjust the schedule according to the following steps:

[0065] S1: Generate a number of first control commands based on the action tasks of the satellite 5 and / or the action tasks of the ground station 6, and in the case that the utility value of the first control command increases before and after its state changes, follow the acceptance of the first The first optimal adjustment of the schedule is made by means of the state change of the control order.

Abstract

The present invention relates to a satellite resource cross-domain collaborative scheduling system, and the optimization management module is configured to optimize and adjust the schedule in the following manner: several first control commands are generated based on the action tasks of the satellite and / or the action tasks of the ground station, Under the condition that the utility value of the first control command increases before and after its state change, the schedule is optimally adjusted for the first time in a manner of accepting the state change of the first control command; based on the state change of the first control command Determine the second control command in the skipped state, at least determine the satellite or ground station associated with it based on the action task information of the second control command, and update the plan based on the real-time status of the satellite or ground station associated with the second control command The table is optimized and adjusted for the second time. Whenever one of the control commands changes, the impact of the change in the state of the control commands can be quickly re-evaluated without considering the remaining control commands.

Description

technical field [0001] The invention belongs to the technical field of satellite control, and in particular relates to a satellite resource cross-domain coordinated scheduling system. Background technique [0002] Different types of satellites can perform tasks such as communication or observation either individually or in concert. For example, Earth observation satellites can image certain areas of the Earth at specific times through the sensors they carry. Using a single satellite to work independently cannot effectively image the entire earth in a short period of time. Or when it is necessary to perform a temporary observation task in a certain area, based on the orbit, altitude and field of view of the satellite, it is often impossible to quickly respond to the execution of the observation task. In order to reduce the time required for the overall imaging of the earth or to quickly respond to the execution of temporary observation tasks, a large number of remote sensin...
