Description

Technical Field

[0002] In recent years, remote sensing satellite systems are no longer limited to periodic passive remote sensing missions in the fields of 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 use their advantages of wide coverage, no terrain restrictions, and all-weather and all-day operations to give full play to their coordinated support capabilities for the entire process of disaster monitoring, identification and evaluation, and provide high-quality and efficient remote sensing information emergency support services for the rescue command decision-making of the commander of the ground rescue command center. As the hub for remote sensing and communication satellite resource scheduling, the ground control system directly determines the effectiveness of remote sensing satellite applications and the quality and timeliness of image data products.

[0003] At present, most remote sensing satellite resources operate in a satellite-ground serial resource management and control mode with the ground as the absolute control subject. Users submit remote sensing needs to the ground satellite control system. After completing the mission planning phase, the control system injects the generated mission instructions to the remote sensing satellite, and the satellite passively receives various control instructions generated by the ground system. After the raw data on the satellite is transmitted to the ground, it is processed to generate remote sensing products and finally fed back to the user. Under this control mode, the satellite and ground businesses are relatively separated, and the synergy advantages of the satellite and the ground are not fully utilized in remote sensing mission planning, data processing and data transmission.

[0043] The description of the embodiments of this specification should be combined with the corresponding drawings, which should be considered as part of the complete specification. In the drawings, the shape or thickness of the embodiments may be enlarged and indicated for simplification or convenience. Furthermore, the parts of each structure in the drawings will be described separately. It is worth noting that the elements not shown in the drawings or not described in words are in a form known to ordinary technicians in the relevant technical field.

[0044] The description of the embodiments herein and any reference to directions and orientations are only for the convenience of description and are not to be construed as any limitation on the scope of protection of the present invention. The following description of the preferred embodiments may involve combinations of features, which may exist independently or in combination, and the present invention is not particularly limited to the preferred embodiments. The scope of the present invention is defined by the claims.

[0045] The present invention provides a satellite-ground coordinated remote sensing satellite emergency control method, which realizes rapid response of emergency support, improves the emergency control capability of remote sensing tasks, and ensures the timely protection of remote sensing information for emergency disaster events through multi-source remote sensing demand analysis, hybrid trigger dynamic management, and integrated planning strategy of remote sensing, processing, measurement and control, and transmission tasks.

[0046] like Figure 1 and Figure 2 As shown, a satellite-ground coordinated remote sensing satellite emergency control method of the present invention comprises the following steps:

[0047] Step S1, analyzing and optimizing multi-source remote sensing mission requirements;

[0048] Step S2: Initiate dynamic rolling planning in response to the task planning requirements of each management and control system;

[0049] Step S3: after the dynamic rolling planning is triggered, remote sensing collaborative resource planning, remote sensing / processing task planning, measurement and control / receiving resource planning, and relay transmission network planning are performed in sequence;

[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 the remote sensing satellite and / or upload them to the communication satellite to complete an emergency plan.

[0051] In some embodiments of the present invention, in step S1, the multi-source remote sensing task requirement is used as input to obtain task information, and the task information at least includes task type, priority and target location;

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

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

[0054] Sort the multi-source remote sensing mission requirements according to the mission type and mission priority, and design the distance threshold of the target center position, such as setting the distance threshold to 10km;

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

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

[0057] In some embodiments of the present invention, in step S2, the dynamic rolling planning is set with an emergency response protection time. In order to optimize the efficiency of the remote sensing system and avoid excessively frequent re-planning, the emergency response protection time is designed to be slightly longer than the system's rolling planning time, such as being set to 1 minute. Therefore, after the hybrid dynamic trigger management module triggers a rolling planning, it will trigger the planning again after 1 minute to ensure the complete execution of a rolling planning.

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

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

[0060] For identification and evaluation tasks, high-resolution imaging satellites are used;

[0061] The satellite to perform the remote sensing mission is determined based on the satellite's existing mission status and the urgency of the mission.

[0062] In some embodiments of the present invention, in 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 partially reordered to generate a new task sequence. At the same time, according to the payload type and the on-board payload data processing capability, the on-board processing of the raw data of the high-priority tasks is given priority, which can greatly shorten the data transmission time.

[0064] Estimate the amount of data with transmission data as input for measurement, control and reception resource planning.

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

[0066] According to the results of remote sensing / processing mission planning, match and plan measurement and control and reception resources, determine the links on the mission, and plan data return 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 measurement and control area, a relay backhaul requirement will be generated.

[0068] The measurement, control and reception links mainly consider two categories: direct transmission to the ground and transmission via relay satellites. Among them, the direct measurement, control or data transmission tasks to the ground can generate measurement, control or data transmission plans through the planning of the corresponding measurement, control and reception resource planning module, that is, the corresponding ground station and occupied time period (the start time and end time of the task). For tasks that cannot upload or download data in time within the measurement and control area, a relay backhaul requirement will be generated, and the relay transmission network planning module will be called to complete the relay transmission network planning.

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

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

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

[0072] The present invention is described in detail below by way of examples.

[0073] Assume that a forest fire breaks out at 22:05 Beijing time on October 5, 2024, with the coordinates of 29.33°N, 115.6°E. The ground emergency rescue commander has successively submitted the need for continuous monitoring of the fire point and the need for high-resolution imaging of the fire point and surrounding villages. Therefore, it is assumed that a detection task is submitted at 22:06:20, with a priority of 3, and the location coordinates are 29.33°N, 115.6°E; a discrimination task is submitted at 22:06:50, with a priority of 1, and the location coordinates are 29.33°N, 115.6°E; a discrimination task is submitted at 22:07:00, with a priority of 5, and the location coordinates are 30.03°N, 115.1°E; a discrimination task is submitted at 22:08:33, with a priority of 5, and the location coordinates are 29.84°N, 115.5°E. 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, 10 high-resolution visible light imaging satellites numbered 2 to 13, and 10 high-resolution SAR imaging satellites numbered 14 to 24. Ground tracking and control stations A and B, and ground data transmission stations C and D.

[0074] The emergency control mode of remote sensing satellite 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 receives four remote sensing tasks:

[0077] Task 1: Detection task, priority 3, location coordinates are 29.33°N, 115.6°E; Task 2: Identification task, priority 1, location coordinates are 29.33°N, 115.6°E; Task 3: Identification task, priority 5, location coordinates are 30.03°N, 115.1°E; Task 4: Identification task, priority 5, location coordinates are 30.13°N, 115.1°E. The four task requirements are first sorted according to priority, and since Task 3 and Task 4 are of the same type, they are judged by the target center position distance threshold and Task 3 and Task 4 are merged. Therefore, after demand analysis, they are merged into three task requirements.

[0078] Step 2: Hybrid dynamic trigger management

[0079] All three task requirements are emergency task requirements, which trigger the task planning link in an event manner. Task requirement one was received at 22:06:20, and task requirement two was received 30 seconds later. Since the reception time interval of task requirements one and two did not meet the minimum time interval of 1 minute for dynamic planning triggering, task requirement two entered the waiting for planning state and did not trigger planning. 10 seconds later, task requirement three was received after the merger of tasks three and four. When the reception time of task one met the minimum time interval of 1 minute for dynamic planning triggering, task requirements 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. Combined with the fire detection requirement, a high-orbit infrared payload satellite is selected to image the target area. For the discrimination task requirements two and three, high-resolution SAR imaging payloads are called to image the target considering the weather factors. According to the satellite's visibility calculation of the target and the satellite's existing plan, high-orbit infrared payload satellite 2 and SAR imaging satellite 18 without mission conflicts are determined to complete the three task requirements. Among them, task requirement one is performed by high-orbit infrared payload satellite 2, and task requirements two and three are performed by SAR imaging satellite 18.

[0082] Step 4: Remote sensing / processing mission planning

[0083] Based on the existing remote sensing mission plan, the high-orbit infrared payload satellite 2 and the SAR imaging satellite 18 are locally reordered to determine the remote sensing plan, that is, the start and end time of imaging. In addition, since satellite 2 does not have on-board processing capabilities, no on-board processing tasks are generated. Satellite 18 has on-board processing capabilities and can generate images of local target areas on-board, which can greatly compress the amount of transmitted data.

[0084] Step 5: Measurement and control / receiving resource planning

[0085] According to the start and end time of the remote sensing mission, the selected ground station A and the start and end time of the command are determined to complete the resource planning of the measurement and control mission. At the same time, both 2 satellites and 18 satellites have the conditions for direct data transmission to the ground, and the direct data transmission method is used to generate the ground reception plan, including the selected ground station C and the start and end time of data reception.

[0086] Step 7: Comprehensive instruction arrangement

[0087] According to the remote sensing, processing mission plan, measurement and control, and receiving mission plan, command templates are used to generate commands for each management and control system, and distributed to each system or uploaded to 2 and 18 satellites.

[0093] Among them, the hybrid dynamic trigger management module can promptly respond to the task planning needs of various control systems to initiate dynamic rolling planning. A complete planning process includes four links: remote sensing collaborative resource planning, remote sensing / processing task planning, measurement and control / receiving resource planning, and relay transmission network planning. The hybrid dynamic trigger management module includes not only emergency event trigger planning, but also periodic time trigger planning. The periodic planning focuses on responding to the normalized monitoring of disaster-prone areas, and the tentative trigger time period of the plan is 1 hour. Emergency event trigger planning is mainly for identification and evaluation tasks with high timeliness requirements.
