[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] The embodiments of the present application provide a resource conflict detection method and system based on a satellite ground station resource pool system, thereby filling the gap in the prior art that there is no method for resource conflict detection for a satellite ground station resource pool system, and achieving fast and flexible resource conflict detection.

[0045] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0046] In order to make up for the lack of a method in the prior art that can realize resource conflict detection of a satellite ground station resource pool system, an embodiment of the present invention designs a resource conflict detection method and system based on a satellite ground station resource pool system, which mainly targets digital resources, signal processing resources and data storage resources in the resource pool system to ensure that the ground station quickly completes the conflict detection of task resources. The embodiment of the present invention first counts the number of various types of tasks whose application task plan overlaps with the existing task plan time and the number of various types of normal resources currently in the satellite ground station, and then compares whether the total number of resources required for the overlapping tasks exceeds the number of various types of resources currently in the system and completes the determination of resource conflicts. The method is easy to implement and has low computational complexity, can quickly realize resource conflict detection, effectively ensure reasonable resource scheduling and no resource conflicts, and normal execution of tasks.

[0047] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0048] The embodiment of the present invention provides a resource conflict detection method based on a satellite ground station resource pool system, the method is executed by a satellite ground station, such as Figure 1 As shown, including:

[0049] S1. Receive a task plan application requirement, wherein the task plan application requirement includes the task type, task start time, and task end time;

[0050] S2. According to the task start time and task end time, count the number of tasks of each type whose application task plan overlaps with the existing task plan time;

[0051] S3. Count the current number of normal resources of various types and the total number of resources required for overlapping tasks;

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

[0053] The embodiment of the present invention determines whether the resources required for the current task plan exceed the maximum capacity of the system by statistically comparing the number of resources required for all overlapping tasks in the time period of the task plan application with the number of various normal resources currently available at the ground station, thereby realizing rapid resource conflict detection. At the same time, the resource conflict detection method proposed in the embodiment of the present invention is simple to implement and has low computational complexity.

[0054] The following is combined with Figure 2 The flowchart shown is used to describe the embodiment of the present invention in detail:

[0055] In one embodiment, S2, based on the task start time and the task end time, count the number of tasks of each type whose application task plan overlaps with the existing task plan time. Specifically, it includes:

[0056] Different task types require different amounts of resources. The definition of task planning time overlap is as follows: Figure 3 As shown, in Figure 3 In the figure, the vertical axis represents time. The overlap of two rectangles in the figure indicates coincidence. The specific definitions include:

[0057] The task start time of the task plan to be applied for is ≤ the task start time of the existing task plan ≤ the task end time of the task plan to be applied for;

[0058] The task start time of the task plan to be applied for is ≤ the task end time of the existing task plan ≤ the task end time of the task plan to be applied for;

[0059] The task start time of the task plan applied for is ≥ the task end time of the existing task plan and the task end time of the task plan applied for is ≤ the task end time of the existing task plan.

[0060] In one embodiment, S3, counting the current number of normal resources of various types and the total number of resources required for overlapping tasks. Specifically including:

[0061] In the embodiment of the present invention, various types of 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 the specific implementation process, more resources can also be considered, such as antenna resources, inverter resources, power amplifier resources, low noise amplifier resources, etc. It should be noted that the normal resources here refer to the resources when the equipment runs normally without faults.

[0062] The total number of resources required for overlapping tasks includes: the number of digital devices required for task type x is x1*X, the number of signal processing boards is x2*X, and the number of data storage servers is x3*X; the number of digital devices required for task type y is y1*Y, the number of signal processing boards is y2*Y, and the number of data storage servers is y3*Y. Among them, x1, x2, x3, y1, y2, and y3 represent the number of resources required for a single task type.

[0063] In one embodiment, S4, compare whether the total number of resources required by the overlapping tasks exceeds the number of various resources currently in the system, and if not, determine that there is no resource conflict for the current task. The specific implementation process is as follows:

[0064] The satellite ground station compares whether the total number of resources required for the overlapping tasks exceeds the number of various resources currently in the system. If not, it is determined that there is no resource conflict for the current task, that is, x1*X+…+y1*Y≤A and x2*X+…+y2*Y≤B and x3*X+…+y3*Y≤C.

[0065] It should be noted that when considering fewer resources, the judgment conditions can be reduced. For example, only the number of signal processing boards B and the number of data storage servers C are considered. When x2*X+…+y2*Y≤B and x3*X+…+y3*Y≤C are met, it can be determined that there is no resource conflict for the current task.

[0066] When more resources are considered, the judgment conditions can be increased according to the above ideas. For example, when antenna resource D is considered, the number of digital devices required for task type x is x1*X, the number of signal processing boards is x2*X, the number of data storage servers is x3*X, and the number of antenna resources is x4*X; the number of digital devices required for task type y is y1*Y, the number of signal processing boards is y2*Y, the number of data storage servers is y3*Y, and the number of antenna resources is y4*Y. When x1*X+…+y1*Y≤A and x2*X+…+y2*Y≤B and x3*X+…+y3*Y≤C and x4*X+…+y4*Y≤D are met, it can be determined that there is no resource conflict for the current task.

[0067] The embodiment of the present invention also provides a resource conflict detection system based on a satellite ground station resource pool system. The resource conflict detection system is installed in a satellite ground station. The resource conflict detection system includes:

[0068] A task plan receiving module is used to receive task plan application requirements; wherein the task plan application requirements include task type, task start time and task end time;

[0069] The first statistical module is used to count the number of tasks of various types whose application task plan overlaps with the existing task plan time according to the task start time and task end time;

[0070] The second statistical module is used to count the current number of normal resources of various types and the total number of resources required for overlapping tasks;

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

[0072] It can be understood that the resource conflict detection system based on the satellite ground station resource pool system provided in the embodiment of the present invention corresponds to the above-mentioned resource conflict detection method based on the satellite ground station resource pool system.

[0074] An embodiment of the present invention also provides an electronic device, comprising: one or more processors; a memory; and one or more programs, wherein the one or more programs are stored in the memory and are configured to be executed by the one or more processors, and the programs include a method for executing the resource conflict detection method based on the satellite ground station resource pool system as described above.

[0075] In summary, compared with the prior art, the present invention has the following beneficial effects:
