Description

Technical Field

[0001] The present invention relates to the technical field of remote sensing technology, and specifically to an emergency task scheduling method for an integrated remote sensing data service platform. Background Art

[0002] With the rapid development of space technology, remote sensing satellites have become an indispensable means for monitoring the changes of the Earth's environment, responding to natural disasters and emergencies. However, in the face of sudden emergency demands, how to quickly and effectively schedule the on-orbit satellite resources of different orbits and different satellite enterprises to obtain real-time remote sensing data of key areas has become a technical problem to be solved urgently in the current remote sensing data service field.

[0003] In the prior art, remote sensing data service platforms usually collect data according to a pre-determined task plan, lacking flexibility and rapid response capabilities for emergency events. When an emergency task occurs, manual intervention is required to adjust the task plan, which is not only inefficient but also may cause the emergency task to be unable to be executed in a timely manner due to resource conflicts. In addition, the emergency data processing process is complex, and the cycle from data reception to product generation is long, making it difficult to meet the rapid response requirements in emergency situations. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an emergency task scheduling method for an integrated remote sensing data service platform to solve the problems raised in the above background art. The present invention optimizes resource allocation, clarifies the implementation path, and ensures the provision of high-quality data support for emergency decision-making within a limited time through intelligent, automated, and market-oriented task scheduling strategies.

[0005] To achieve the above purpose, the present invention is realized through the following technical solutions: An emergency task scheduling method for an integrated remote sensing data service platform includes the following steps:

[0006] Step 1, start the emergency response mode: When an emergency data task request is received, the system automatically identifies and switches to the emergency data response mode;

[0007] Step 2, comprehensive scheduling of satellite resources: Conduct a preliminary task plan for the orbital information and payload data of on-orbit satellite resources, and confirm the task execution unit;

[0008] Step 3, acquisition and processing of emergency data: After the satellite completes data collection according to the instructions, the data is quickly transmitted to the data processing center through the satellite-ground station link to generate remote sensing image data products;

[0009] Step 4, end the emergency response mode: After the emergency data task is completed, evaluate the task execution effect.

[0010] Further, in Step 1, after the emergency response mode is activated, the system immediately suspends or cancels all non-emergency programming data tasks to ensure that all satellite resources and ground station resources give priority to serving emergency tasks.

[0011] Further, in Step 2, identify satellite resource enterprises capable of handling this task and complete the preliminary task planning.

[0012] Further, according to the historical data response situation and rules, confirm the user demand assignment mode and automatically allocate the task requirements to satellite resource enterprises for response.

[0013] Further, after confirming the task execution unit, the system provides real-time feedback of the planning results to the user, including key information such as the expected data acquisition time and coverage area.

[0014] Further, the data processing module in Step 3 integrates image processing and information extraction algorithms, and the remote sensing image data products are used to meet emergency needs.

[0015] Further, in Step 4, after confirming that all emergency needs have been met, exit the emergency data response mode.

[0016] Further, after the emergency data response mode is exited, the original task scheduling mechanism is automatically restored to continue executing the suspended programming data tasks.

[0017] Further, the user demand assignment mode includes a single satellite resource enterprise supporting the emergency task mode, a mode where one enterprise is the main and others are supplementary to support the emergency task, and a mode where multiple satellite resource enterprises jointly support the emergency task.

[0018] Further, the integrated remote sensing data service platform needs to receive user demands and analyze them, and perform corresponding task responses according to the complexity and urgency of the demands.

The flowchart of this method is as Figure 1 shown, and specifically includes the following steps:

[0030] 1. Start the emergency response mode:

[0031] When receiving an emergency data task request, the system automatically identifies and switches to the emergency data response mode.

[0032] In this mode, the system immediately suspends or cancels all non-emergency programming data tasks to ensure that all satellite resources and ground station resources give priority to emergency tasks.

[0033] 2. Comprehensive scheduling of satellite resources:

[0034] Conduct preliminary mission planning based on the orbital information and payload data of on-orbit satellite resources, identify satellite resource enterprises capable of handling this mission, and complete the preliminary mission planning. According to past data response situations and rules, confirm the user demand assignment mode, automatically allocate the mission requirements to satellite resource enterprises for response. After confirming the mission execution unit, the system will provide real-time feedback of the planning results to the user, including key information such as the expected data acquisition time and coverage area.

[0035] 3. Emergency data acquisition and processing:

[0036] After the satellite completes data acquisition according to the command, the data is quickly transmitted to the data processing center through the satellite-ground station link. The data processing module integrates advanced algorithms such as image processing and information extraction to quickly generate remote sensing image data products that meet emergency requirements.

[0037] 4. End of emergency response mode:

[0038] After the emergency data mission is completed, the system automatically evaluates the mission execution effect. After confirming that all emergency requirements have been met, it exits the emergency data response mode. Resume the original mission scheduling mechanism and continue to execute the suspended programmed data mission.

[0039] In the above method, the algorithm automatically completes the identification of emergency missions and the preliminary planning of satellite resources, and then combines with human intervention to assign the mission to multiple units. The designed business model in the whole process is feasible and can significantly improve the reliability of emergency response missions; dynamically adjust resource allocation, establish a service model for multiple satellite resource enterprises to handle emergency missions, and ensure the maximization of resource utilization in case of emergencies.

[0040] This embodiment also provides the emergency mission scheduling process of the remote sensing data service platform, and the specific content is as follows:

[0041] 1. The user submits mission requirements to the Comprehensive Remote Sensing Data Service Platform (hereinafter referred to as the "Platform");

[0042] 2. The Platform collects mission requirements from the user and extracts mission requirements;

[0043] 3. The Platform makes overall arrangements for all mission completion time points and mission priorities, preliminarily screens satellite resource enterprises suitable for this round of mission planning, and selects a suitable mission mode in the "User Demand Assignment Mode" to assign the mission to satellite resource enterprises;

[0044] 4. The satellite resource enterprise receives the mission assigned by the Platform, analyzes the satisfaction of its own resources with the mission requirements, and then confirms or rejects the assigned mission;

[0045] 5. The platform determines the final task-executing enterprise based on the task confirmation of each satellite resource enterprise. If there is no enterprise that can complete the task, the platform needs to re-plan and re-assign the task. If it is really unable to respond to the task requirement, it needs to promptly feedback to the user;

[0046] 6. The satellite resource enterprise completes the task as required and transmits the data result back to the platform;

[0047] 7. The platform completes data acquisition and aggregation, data storage management, data fusion governance, data intelligent analysis, and data application services, and finally delivers the result to the user.

[0048] This embodiment designs various task assignment modes in combination with real task practice experience, enabling different tasks to be promoted and carried out in a targeted manner to ensure better task effects.

[0049] This embodiment also provides a specific user requirement assignment mode: The user requirement assignment mode includes three situations. The integrated remote sensing data service platform needs to receive the user requirements and analyze them, and make corresponding task responses according to the complexity and urgency of the requirements:

[0050] (1) As Figure 3 shown, the single satellite resource enterprise supports the emergency task mode: The integrated remote sensing data service platform assigns the task to a certain commercial satellite enterprise to complete task assignment, shooting task, data processing, and data access.

[0051] (2) As Figure 4 shown, the mode of one enterprise as the main and others as backups to support the emergency task: The integrated remote sensing data service platform assigns the task to multiple commercial satellite enterprises. One enterprise mainly undertakes the task, and other enterprises act as backups.

[0052] (3) As Figure 5 shown, the mode of multiple satellite resource enterprises jointly supporting the emergency task: The integrated remote sensing data service platform assigns the task to multiple commercial satellite enterprises, and multiple enterprises jointly complete the task.
