Description

Technical Field

[0001] This invention relates to the field of satellite-ground collaborative remote sensing technology, and in particular to a satellite-ground collaborative remote sensing satellite emergency management method. Background Technology

[0002] In recent years, remote sensing satellite systems have expanded beyond periodically and passively performing remote sensing missions in areas such as environmental monitoring, resource exploration, agricultural management, urban planning, and national security. In emergency response missions for sudden disasters such as earthquakes, typhoons, floods, and fires, remote sensing satellites leverage their advantages—wide coverage, lack of terrain limitations, and all-weather, all-time operation—to fully utilize their collaborative support capabilities throughout the entire process of disaster monitoring, identification, and assessment. This provides high-quality and efficient remote sensing information emergency support services for ground-based command center commanders' rescue command decisions. The ground control system, as the central hub for the scheduling of remote sensing and communication satellite resources, directly determines the effectiveness of remote sensing satellite applications and the quality and timeliness of image data products.

[0003] Currently, most remote sensing satellite resources operate in a serial resource management mode with the ground as the absolute control entity. Users submit their remote sensing requirements to the ground satellite control system. After completing the mission planning phase, the control system uploads the generated mission instructions to the remote sensing satellite, which passively receives various control instructions generated by the ground system. After the raw data from the satellite is transmitted to the ground, it is processed to generate remote sensing products and ultimately fed back to the user. Under this management mode, satellite and ground operations are relatively separated, and the synergistic advantages of satellite and ground are not fully utilized in remote sensing mission planning, data processing, and data transmission.

[0004] Therefore, designing a space-ground collaborative emergency management method for remote sensing satellites to enhance the emergency support capability of remote sensing satellite resources is an urgent problem to be solved. Summary of the Invention

[0042] Figure 3 This diagram illustrates the composition of a satellite-ground collaborative remote sensing emergency control system according to one embodiment of the present invention. Detailed Implementation

[0043] The description of the embodiments in this specification should be taken in conjunction with the accompanying drawings, which should form part of the complete specification. In the drawings, the shape or thickness of the embodiments may be exaggerated and may be indicated in a simplified or convenient manner. Furthermore, parts of the various structures in the drawings will be described separately; it is worth noting that elements not shown in the figures or not described in words are in a form known to those skilled in the art.

[0044] The descriptions of the embodiments herein, including any references to directions and orientations, are for ease of description only and should not be construed as limiting the scope of the invention. The following description of preferred embodiments involves combinations of features, which may exist independently or in combination; the invention is not particularly limited to the preferred embodiments. The scope of the invention is defined by the claims.

[0045] This invention provides a satellite-ground collaborative remote sensing emergency management method. Through multi-source remote sensing demand analysis, hybrid trigger dynamic management, and an integrated planning strategy for remote sensing, processing, telemetry, and control and transmission tasks, it achieves rapid response in emergency support, enhances the emergency management capability of remote sensing missions, and ensures the timely protection of remote sensing information for emergency disaster events.

[0046] like Figure 1 and Figure 2 As shown, the present invention provides a satellite-ground collaborative remote sensing satellite emergency management method, comprising the following steps:

[0047] Step S1: Analyze and optimize the requirements of multi-source remote sensing tasks;

[0048] Step S2: Initiate dynamic rolling planning in response to the task planning requirements of various control systems;

[0049] Step S3: After triggering the dynamic rolling planning, remote sensing collaborative resource planning, remote sensing / processing task planning, telemetry / control / receiving resource planning, and relay transmission network planning are performed sequentially.

[0050] Step S4: Generate instructions for each control system based on the instruction template, and distribute them to each control system and / or upload them to remote sensing satellites and / or communication satellites to complete an emergency planning.

[0051] In some embodiments of the present invention, in step S1, task information is obtained by taking the multi-source remote sensing task requirements as input, and the task information includes at least task type, priority and target location.

[0052] The task types include at least monitoring, discrimination, and evaluation tasks;

[0053] The priority is used to indicate the urgency of the task, such as priority 1 to 10, with the smaller the value, the higher the priority;

[0054] The requirements of multi-source remote sensing tasks are sorted according to task type and task priority, and a target center location distance threshold is designed, such as setting a distance threshold of 10km.

[0055] The tasks are merged based on the distance to the target location to obtain optimized task requirements.

[0056] The optimized task requirements serve as input to the hybrid dynamic trigger management module.

[0057] In some embodiments of the present invention, step S2 includes an emergency response protection time for the dynamic rolling planning. To optimize the performance of the remote sensing system and avoid excessively frequent replanning, the emergency response protection time is designed to be slightly longer than the system's single rolling planning time, such as 1 minute. Therefore, after the hybrid dynamic trigger management module triggers a rolling plan once, it will trigger the planning again after 1 minute, ensuring the complete execution of a single rolling plan.

[0058] In some embodiments of the present invention, in step S3, collaborative remote sensing resource planning is the first step of the planning process. This collaborative remote sensing resource planning is used to plan remote sensing satellite resources according to the mission type and target location, including:

[0059] For surveillance missions, high-orbit imaging satellites and low-orbit microwave search satellites are used.

[0060] For discrimination and evaluation tasks, high-resolution imaging satellites are used.

[0061] The satellites to be used for remote sensing missions are determined based on their existing mission status and the urgency of the mission.

[0062] In some embodiments of the present invention, step S3, the remote sensing / processing task planning includes:

[0063] Based on the existing remote sensing mission plan, the tasks assigned to each satellite are locally reordered to generate a new mission sequence. At the same time, according to the payload type and on-board payload data processing capabilities, the on-board processing of raw data for high-priority tasks is prioritized, which can significantly reduce data transmission time.

[0064] The estimated amount of data to be transmitted is used as input for the planning of measurement, control, and receiving resources.

[0065] In some embodiments of the present invention, step S3, the planning of measurement, control, and reception resources includes:

[0066] Based on the results of remote sensing / processing mission planning, match and plan telemetry, tracking and control and receiving resources, determine the links for mission uploading, and plan data backhaul resources based on the results of on-board processing after mission execution.

[0067] For tasks that cannot upload or download data in a timely manner within the monitoring and control area, a relay backhaul request will be generated.

[0068] The telemetry, tracking, and command (TT&C) and receiving links mainly consider two categories: direct ground-to-ground transmission and transmission via relay satellites. For direct ground-to-ground TT&C or data transmission tasks, a TT&C or data transmission plan can be generated through the corresponding TT&C and receiving resource planning module, specifying the corresponding ground stations and the occupied time periods (task start and end times). For tasks where data cannot be uploaded or downloaded in a timely manner within the TT&C area, a relay backhaul request will be generated, and the relay transmission network planning module will be invoked to complete the relay transmission network planning.

[0069] In some embodiments of the present invention, step S3, the relay transmission network planning includes:

[0070] Based on the planning results of receiving resources and the estimated amount of data to be transmitted on the satellite, the mission planning of the relay communication satellite is carried out, and a relay communication plan is generated.

[0071] The relay communication plan includes the transmission time period of the remote sensing satellite and the communication time period of the relay satellite.

[0072] The present invention will be described in detail below by way of embodiments.

[0073] Suppose a forest fire breaks out at 22:05 Beijing time on October 5, 2024, at coordinates 29.33°N, 115.6°E. The ground emergency response commander successively reports the need for continuous monitoring of the fire site and high-resolution imaging of the fire site and surrounding villages. Therefore, assume the following tasks are reported: Detection task (priority 3) at 22:06:20 (29.33°N, 115.6°E); Judgment task (priority 1) at 22:06:50 (29.33°N, 115.6°E); Judgment task (priority 5) at 22:07:00 (30.03°N, 115.1°E); Judgment task (priority 5) at 22:08:33 (29.84°N, 115.5°E). The remote sensing satellite resources include: two high-orbit satellites, visible light payload satellite number 1 and infrared payload satellite number 2; 20 low-orbit satellites, including 10 high-resolution visible light imaging satellites numbered 2–13 and 10 high-resolution SAR imaging satellites numbered 14–24; ground control stations A and B; and ground data transmission stations C and D.

[0074] The specific emergency management and control mode based on satellite-ground collaboration is as follows:

[0075] Step 1: Multi-source remote sensing requirements analysis

[0076] The multi-source remote sensing demand analysis module received four remote sensing tasks:

[0077] Task 1 is a detection task, priority 3, location coordinates are 29.33°N, 115.6°E; Task 2 is a discrimination task, priority 1, location coordinates are 29.33°N, 115.6°E; Task 3 is a discrimination task, priority 5, location coordinates are 30.03°N, 115.1°E; Task 4 is a discrimination task, priority 5, location coordinates are 30.13°N, 115.1°E. The four task requirements are first sorted according to priority. Since Task 3 and Task 4 are of the same type, they are merged after determining the distance threshold to the target center location. Therefore, after requirement analysis, they are merged into three task requirements.

[0078] Step 2: Hybrid Dynamic Trigger Management

[0079] All three task requirements were emergency-type, triggering the task planning phase via events. Task requirement one was received at 22:06:20, and task requirement two was received 30 seconds later. Because the time interval between receiving task requirement one and task requirement two did not meet the minimum dynamic programming trigger interval of one minute, task requirement two entered a pending planning state and was not triggered. Ten seconds later, task requirement three, a merged version of tasks three and four, was received. Once the time of receiving task one met the minimum dynamic programming trigger interval of one minute, tasks two and three triggered the complete process again. Thus, by triggering the planning process twice, the response to the three task requirements was completed.

[0080] Step 3: Collaborative Remote Sensing Resource Planning

[0081] Collaborative remote sensing resource planning is the first step in the planning process. Task requirement one is a surveillance task, which, in conjunction with fire detection requirements, involves selecting a high-orbit infrared payload satellite to image the target area. For task requirements two and three, which are discrimination tasks, considering weather conditions, a high-resolution SAR imaging payload is used to image the target. Based on satellite visibility calculations and existing satellite schedules, two high-orbit infrared payload satellites (2 and 18) without mission conflicts are selected to complete the three task requirements. Task requirement one is performed by high-orbit infrared payload satellite 2, while tasks two and three are performed by SAR imaging satellite 18.

[0082] Step 4: Remote Sensing / Processing Task Planning

[0083] For both the high-orbit infrared payload satellite 2 and the SAR imaging satellite 18, based on existing remote sensing mission plans, local reordering was performed to determine the remote sensing schedule, specifically the start and end times for imaging. Furthermore, since satellite 2 lacks onboard processing capabilities, no onboard processing tasks were generated. Satellite 18, however, possesses onboard processing capabilities and can generate images of local target areas, significantly reducing the amount of data transmitted.

[0084] Step 5: Planning of Measurement and Control / Reception Resources

[0085] Based on the start and end times of the remote sensing mission, the selection of ground station A and the start and end times of the command annotations are determined, thus completing the resource planning for the telemetry and control mission. Simultaneously, both satellites 2 and 18 possess direct ground data transmission capabilities, and a ground reception plan is generated using the direct ground data transmission method, including the selected ground station C and the data reception start and end times.

[0086] Step 7: Comprehensive Instruction Arrangement

[0087] Based on the remote sensing and processing mission plans, and the telemetry, control and reception mission plans, instructions for each control system are generated using instruction templates and distributed to each system or uploaded to satellites 2 and 18.

[0088] like Figure 3 As shown, according to one aspect of the present invention, a satellite-ground collaborative remote sensing satellite emergency management system is provided, comprising:

[0089] The requirements analysis module is used to analyze and optimize the requirements of multi-source remote sensing tasks;

[0092] The instruction generation module is used to generate instructions for various control systems based on instruction templates, and distribute them to various control systems and / or upload them to remote sensing satellites and / or communication satellites to complete an emergency planning.

[0093] The hybrid dynamic triggering management module can promptly respond to the task planning needs of various control systems and initiate dynamic rolling planning. A complete planning process includes four stages: remote sensing collaborative resource planning, remote sensing / processing task planning, telemetry / control / receiving resource planning, and relay transmission network planning. The hybrid dynamic triggering management module includes not only emergency event-triggered planning but also periodic time-triggered planning. Periodic planning focuses on responding to routine monitoring in disaster-prone areas, with a tentative triggering time cycle of one hour. Emergency event-triggered planning is mainly for tasks with high timeliness requirements, such as discrimination and assessment tasks.
