[0002] The satellite ground station primarily performs satellite telemetry, tracking, and command (TT&C) and data transmission tasks. The resource pool, as the core system of the satellite ground station, consists of digital resources, signal processing resources, and data storage and distribution resources.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] This application provides a resource conflict detection method and system based on a satellite ground station resource pool system, filling the gap in the prior art where there is no method for resource conflict detection in a satellite ground station resource pool system, and achieving fast and flexible resource conflict detection.

[0045] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0046] To address the current lack of a method for resource conflict detection in satellite ground station resource pool systems, this invention presents a method and system for resource conflict detection based on such a system. The system primarily targets digital resources, signal processing resources, and data storage resources within the resource pool, ensuring the ground station can quickly detect resource conflicts. This invention first counts the number of tasks of each type whose requested task plans overlap with existing task plans, and then compares the current quantity of various types of normal resources at the satellite ground station. It then compares the total number of resources required by the overlapping tasks to determine if they exceed the current quantity of various types of resources in the system, thus identifying resource conflicts. The method is easy to implement, has low computational complexity, and can quickly detect resource conflicts, effectively ensuring reasonable resource scheduling without conflicts, and guaranteeing normal task execution.

[0047] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0048] This invention provides a resource conflict detection method based on a satellite ground station resource pool system. This method is executed by the satellite ground station, such as... Figure 1 As shown, it includes:

[0049] S1. Receive task plan request requests; the task plan request requests include the task type, task start time, and task end time.

[0050] S2. Based on the task start time and task end time, count the number of each type of task whose application task plan overlaps with the existing task plan time.

[0051] S3. Calculate the current quantity of various normal resources and the total quantity of resources required for overlapping tasks;

[0052] S4. Compare whether the total number of resources required by overlapping tasks exceeds the current number of various types of resources in the system. If it does not exceed the current number of resources, it is determined that there is no resource conflict for the current task.

[0053] This invention enables rapid resource conflict detection by statistically comparing the resource requirements of all overlapping tasks within the same time period with the existing normal resources at the ground station.

[0054] The following is combined with, for example Figure 2 The flowchart shown below provides a detailed description of the embodiments of the present invention:

[0055] In one embodiment, S2, based on the task start time and task end time, count the number of tasks of each type whose requested task plan and existing task plan times overlap. Specifically, this includes:

[0056] Different task types require different amounts of resources, and the definition of overlapping task schedules is as follows: Figure 3 As shown, in Figure 3 In the graph, the vertical axis represents time, and the overlapping areas of two rectangles indicate that they coincide. Specific definitions include:

[0057] The start time of the requested task plan must be less than or equal to the start time of the existing task plan and the end time of the requested task plan.

[0058] The start time of the requested task plan must be less than or equal to the end time of the existing task plan;

[0059] The start time of the applied task plan must be greater than or equal to the start time of the existing task plan, and the end time of the applied task plan must be less than or equal to the end time of the existing task plan.

[0060] In one embodiment, S3 involves calculating the current quantity of various normal resources and the total quantity of resources required by overlapping tasks. Specifically, this includes:

[0061] In this embodiment of the invention, the various normal resources mainly consider the number of digital devices (A), the number of signal processing boards (B), and the number of data storage servers (C). It should be noted that in actual implementation, more resources can be considered, such as antenna resources, frequency converter resources, power amplifier resources, low-noise amplifier resources, etc. It should be clarified that normal resources here refer to resources when the equipment is operating normally without faults.

[0062] The total amount of resources required for overlapping tasks includes: task type x The number of digital devices required for the task plan is x 1 * X Number of signal processing boards x 2 *X Number of data storage servers x 3 *X One, task type y The number of digital devices required for the task plan is y 1 *Y Number of signal processing boards y 2 *Y Number of data storage servers y 3 *Y One. Among them, x 1 、x 2 、 x 3 、y 1 、y 2 、y 3 represents the quantity of each type of resource required for a single task type; X Indicates overlapping task types x Number of planned tasks; Y Indicates overlapping task types y The number of planned tasks.

[0063] In one embodiment, step S4 compares whether the total number of resources required by overlapping tasks exceeds the current number of various types of resources in the system. If it does not exceed the current number of resources, it is determined that there is no resource conflict for the current task. The specific implementation process is as follows:

[0064] The satellite ground station checks whether the total number of resources required for overlapping tasks exceeds the current number of various types of resources in the system. If not, it determines that there is no resource conflict for the current task. x 1 *X+…+y 1 *Y≤A and x 2 *X+…+y 2 *Y≤B and x 3 *X+…+ y 3 *Y≤C .

[0065] It should be noted that when considering fewer resources, the number of judgment conditions can be reduced. For example, if only the number of signal processing boards (B) and the number of data storage servers (C) are considered, then when the conditions are met... x 2 *X+…+y 2 *Y≤B and x 3 *X+…+y 3 *Y≤C If this is the case, it can be determined that there are no resource conflicts in the current task.

[0066] When considering more resources, simply add more conditions to the judgment following the above approach. For example, when considering antenna resource D, the task type... x The number of digital devices required for the task plan is x 1 *X Number of signal processing boards x 2 *X Number of data storage servers x 3 *X The number of antenna resources is [number]. x 4 *X Task type y The number of digital devices required for the task plan is y 1 *Y Number of signal processing boards y 2 *Y Number of data storage servers y 3 *Y The number of antenna resources is [number]. y 4 *Y When it meets the requirements x 1 *X+… +y 1 *Y≤A and x 2 *X+…+y 2 *Y≤B and x 3 *X+…+y 3 *Y≤C and x 4 *X+…+y 4 *Y≤D If this is the case, it can be determined that there are no resource conflicts in the current task.

[0068] The task plan receiving module is used to receive task plan request requests; the task plan request requests include the task type, task start time, and task end time.

[0069] The first statistics module is used to count the number of various types of tasks whose application task plans overlap with existing task plans based on the task start time and task end time.

[0070] The second statistics module is used to count the current quantity of various normal resources and the total quantity of resources required for overlapping tasks.

[0071] The judgment module is used to compare whether the total number of resources required by overlapping tasks exceeds the current number of various types of resources in the system. If it does not exceed the current number of resources, it is determined that there is no resource conflict for the current task.
