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.

[0025] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0026] Embodiment 1

[0027] Figure 1 A flow chart of a resource planning method for a communication satellite system provided by an embodiment of the present invention is as follows: Figure 1 As shown, the method specifically comprises the following steps:

[0028] Step S102, obtaining multiple communication satellite resource usage plans sent by multiple user centers within a target time period.

[0029] In the prior art, the communication satellite system will process the resource use plans sent by each user center in batches according to time periods. For example, the resource use plans proposed by multiple user centers between 8:00 and 12:00 will be processed uniformly by the communication satellite system after 12:00 on the same day; the resource use plans proposed by multiple user centers between 12:00 and 16:00 will be processed uniformly by the communication satellite system after 08:00 the next day. In other words, when performing resource planning, the communication satellite system needs to obtain multiple resource use plans sent by multiple user centers within the target time period. The target time period is the last centralized application time period before the current moment. The embodiment of the present invention does not specifically limit the time range and number of the centralized application time period. Users can configure according to actual needs. In addition, the number of communication satellite resource use plans sent by each user center is not limited.

[0030] The user center refers to the engineering measurement and control center or business measurement and control center, application center, and other users of the user target, such as the control center or command and control unit of the electronic reconnaissance ship and unmanned aerial vehicle equipped with the user target terminal. Among them, the user target refers to various spacecraft, long-range reconnaissance aircraft, electronic reconnaissance ships, etc. equipped with communication satellite terminals. Through the user target terminal, the communication satellite can establish an intersatellite link with the user target, and complete the data transmission between the user center and the user target through this intersatellite link, or implement measurement and control of the user target.

[0031] Step S104, determining a plan to be merged from a plurality of communication satellite resource utilization plans.

[0032] In order to improve the utilization rate of communication satellite resources, an embodiment of the present invention proposes a strategy for reasonably merging the communication satellite resource use plans of different user centers. Specifically, after obtaining multiple communication satellite resource use plans, first determine the plan to be merged, wherein the plan to be merged represents that the main tracking user target and the auxiliary tracking user target are consistent, or the single tracking user target is consistent, or the main tracking user target and the single tracking user target are consistent, and there are several communication satellite resource use plans that overlap in the mission time period. The embodiment of the present invention does not specifically limit the number of communication satellite resource use plans included in the plan to be merged, and multiple plans that meet the above conditions constitute the plan to be merged, that is, the number of communication satellite resource use plans in the plan to be merged is greater than or equal to 2.

[0033] In order to facilitate the understanding of the plans to be merged, an example is given below. Assuming that among multiple communication satellite resource utilization plans, user center A sends a dual-user target plan (primary tracking user target 1, auxiliary tracking user target 2) to perform space-based measurement and control tasks, and user center B sends a dual-user target plan (primary tracking user target 1, auxiliary tracking user target 2) to perform data transmission tasks, that is, the primary and secondary characteristics of the dual-user targets of the two user centers are consistent, and it is known that the task period of the user center A plan overlaps with the task period of the user center B plan. Therefore, since the primary tracking user targets and the auxiliary tracking user targets of user centers A and B are consistent, and the task periods overlap, the communication satellite resource utilization plan sent by user center A and the communication satellite resource utilization plan sent by user center B are plans to be merged. In the embodiment of the present invention, the task period of the dual-target plan of a single user center is the union (including the interval part) of the plan period of its primary tracking user target and the plan period of the auxiliary tracking user target.

[0034] For another example, user center A sends a usage plan to apply only for space-based tracking and control tasks for user target 1, that is, user target 1 is a single tracking user target of user center A, and user center B sends a usage plan to apply only for space-based tracking and control tasks for user target 1, that is, user target 1 is also a single tracking user target of user center B, and it is known that the task period of user center A overlaps with the task period of user center B. Therefore, since the single tracking user targets of user center A and user center B are consistent, and the task periods overlap, the communication satellite resource usage plan sent by user center A and the communication satellite resource usage plan sent by user center B are plans to be merged.

[0035] For another example, user center A sends a usage plan to apply only for the space-based tracking and control task for user target 1, that is, user target 1 is the single tracking user target of user center A, and user center B sends a dual user target plan (primary tracking user target 1, auxiliary tracking user target 2) to perform the data transmission task, and it is known that the task period of user center A overlaps with the task period of user center B. Therefore, since the single tracking user target of user center A is consistent with the primary tracking user target of user center B, and the task periods overlap, the communication satellite resource usage plan sent by user center A and the communication satellite resource usage plan sent by user center B are plans to be merged.

[0036] That is to say, the plan to be merged indicates that the main tracking user target and the auxiliary tracking user target are consistent, and there are several overlapping communication satellite resource utilization plans in the mission period; or it indicates that the single tracking user target is consistent, and there are several overlapping communication satellite resource utilization plans in the mission period; or it indicates that the main tracking user target is consistent with the single tracking user target, and there are several overlapping communication satellite resource utilization plans in the mission period.

[0037] Step S106, when it is determined that the task execution template of the same user target in the plan to be merged is unique, if there is no resource conflict between the plan to be merged and other communication satellite resource utilization plans, the plans to be merged are merged and the updated communication satellite resource utilization plan is fed back to the corresponding user center.

[0038] Among them, other communication satellite resource utilization plans represent the communication satellite resource utilization plans other than the plan to be merged among the multiple communication satellite resource utilization plans acquired in the above step S102.

[0039] In the embodiment of the present invention, the premise that the communication satellite resource use plans can be merged is that the plans to be merged use the same task execution template for the same user target, that is, if different task execution templates are used for the same user target in the several communication satellite resource use plans to be merged, the plans cannot be merged. Optionally, the task execution template includes: task preparation time, antenna tracking mode, parameter injection mode and task recovery state mode. The embodiment of the present invention does not specifically limit the content of the task execution template, and the user can also add items according to actual needs.

[0040] If it is determined that the task execution template for the same user target in the plan to be merged is unique, it is necessary to further determine whether there is a resource conflict between the plan to be merged and other communication satellite resource utilization plans. If it is determined that there is no resource conflict, the plans to be merged (that is, the above-mentioned several communication satellite resource utilization plans) can be merged, and then the updated communication satellite resource utilization plan can be fed back to each user center, that is, the application result of the resource utilization plan initiated by it is fed back to each user center. If it is a user center that does not participate in the plan merger, the application approval or failure will be directly fed back; if it is a user center that participates in the plan merger, the merged plan will be synchronously fed back while the application approval is fed back.

[0041] Taking the dual-target plan sent by user center A and the dual-target plan sent by user center B as an example, after the two plans are merged, user center A and user center B will use the same antenna to simultaneously implement data transmission tasks / space-based measurement and control tasks for two user targets. Compared with the existing technology that requires the use of two antennas to complete the task, the resource utilization of the communication satellite system is significantly improved.

[0042] The present invention provides a resource planning method for a communication satellite system. First, multiple communication satellite resource use plans sent by multiple user centers within a target time period are obtained, and then a plan to be merged is determined from the multiple communication satellite resource use plans; wherein the plan to be merged indicates that a primary tracking user target and an auxiliary tracking user target are consistent, or a single tracking user target is consistent, or a primary tracking user target and a single tracking user target are consistent, and there are several communication satellite resource use plans overlapping in the task time period; next, when it is determined that the task execution template of the same user target in the plan to be merged is unique, if there is no resource conflict between the plan to be merged and other communication satellite resource use plans, the plan to be merged is merged, and the updated communication satellite resource use plan is fed back to the corresponding user center. Based on this method, the communication satellite resource use plans of several user centers can be merged, so that the resource utilization rate of the communication satellite system can be effectively improved.

[0043] In an optional implementation, the task period includes: a task preparation period, a task execution period and a task cleanup period; in the above step S106, merging the plans to be merged specifically includes the following steps:

[0044] Step S1061, obtaining the start time of the task preparation period, the start time of the task execution period, the end time of the task execution period and the end time of the task cleanup period of each communication satellite resource usage plan in the plan to be merged.

[0045] Step S1062, taking the earliest start time among the start times of all task preparation periods as the start time of the task preparation period of the target merge plan; wherein the target merge plan represents the communication satellite resource usage plan after merging the plans to be merged.

[0046] Step S1063: The earliest start time among the start times of all task execution periods is used as the start time of the task execution period of the target merged plan.

[0047] Step S1064: The latest end time among the end times of all task execution periods is used as the end time of the task execution period of the target merged plan.

[0048] Step S1065: The latest end time among the end times of all task cleanup periods is used as the end time of the task cleanup period of the target merged plan.

[0049] That is to say, the start time of the task execution period and the start time of the task preparation period of the target merged plan are taken as the earliest time, and the end time of the task execution period and the end time of the task cleanup period are taken as the latest time. For ease of understanding, the following takes the communication satellite resource utilization plan of two user centers as an example to illustrate the merger of plans.

[0050] Figure 2 When the task execution period of user center A completely includes the task execution period of user center B, the task period distribution diagram of the target merge plan is as follows: Figure 3 This is a diagram of the task time distribution of the target merge plan when the task execution time of user center A overlaps but does not completely include the task execution time of user center B. Figure 4 This is a diagram of the task time period distribution of the target merge plan when there is no overlap between the task execution time period of user center A and the task execution time period of user center B. However, when there is overlap between the task time periods,

[0051] In an optional implementation, when it is determined that the task execution template of the same user goal in the plan to be merged is unique, the method of the present invention further includes the following content:

[0052] If there is a target plan in the plan to be merged that has a resource conflict with other communication satellite resource usage plans, the first task priority of the target plan and the second task priority of the conflicting plan that has a resource conflict with the target plan are obtained.

[0053] It is determined whether the first task priority is greater than the second task priority.

[0054] If so, the plans to be merged are merged and the conflicting plans are rejected.

[0055] If no, the target plan is rejected and the conflicting plan is passed.

[0056] Specifically, taking the example of all communication satellite resource utilization plans currently received by the communication satellite system as H1, H2, T1, and T2, assuming that the plans sorted according to the order of the start time of the task period are: T1, H1, H2, and T2, and H1 and H2 have been determined as plans to be merged, then if the H1 plan has a resource conflict with the T1 plan, that is, the H1 plan is the above-mentioned target plan, and the T1 plan is the above-mentioned conflicting plan, then the task priorities of the two are obtained. If the task priority of the H1 plan is greater than the task priority of the T1 plan, then H1 and H2 are merged and the T1 plan is rejected. Otherwise, the H1 plan is rejected and the T1 plan is satisfied.

[0057] If there is a resource conflict between plan H2 and plan T2, that is, plan H2 is the above-mentioned target plan and plan T2 is the above-mentioned conflicting plan, then obtain the task priorities of the two. If the task priority of plan H2 is greater than the task priority of plan T2, then merge H1 and H2 and reject plan T2. ​​Otherwise, reject plan H2 and satisfy plan T2.

[0058] In the embodiment of the present invention, after the plans to be merged are merged, the task priority of the target merged plan is the highest task priority among all the communication satellite resource usage plans in the plans to be merged. That is, if H1 and H2 are the plans to be merged, and the task priority of the H2 plan is greater than the task priority of the H1 plan, then after H1 and H2 are merged, the task priority of the target merged plan H is consistent with the task priority of the H2 plan.

[0059] In an optional implementation manner, after obtaining the target merging plan, the method of the present invention further comprises the following steps:

[0060] Step S201, receiving a task period adjustment request for a target communication satellite resource utilization plan of the center sent by a target user center; wherein the target user center represents any user center among several user centers participating in the plan merging.

[0061] Step S202, when it is determined that the time difference between the sending time of the mission period adjustment request and the start time of the target merge plan is greater than a preset time threshold, the target communication satellite resource usage plan is adjusted based on the mission period adjustment request to obtain an adjusted plan.

[0062] That is to say, for the merged plan (that is, the target merged plan), if one of the user centers participating in the plan merge wants to adjust its plan, the user center needs to submit a task period adjustment request some time before the start of the target merged plan, and the request will be accepted, otherwise the communication satellite system will refuse to adjust the plan.

[0063] Step S203, determining whether there is overlap between the task time periods of the adjusted plan and the remaining plans in the plan to be merged.

[0064] If it exists, execute the following step S204; if it does not exist, execute the following step S205.

[0065] Step S204, updating the plan to be merged, and based on the resource conflict detection result between the updated plan to be merged and other unexecuted communication satellite resource utilization plans, updating the communication satellite resource utilization plan of the relevant user center.

[0066] Step S205: deleting the target merging plan, and replanning the resources of the communication satellite system based on all unexecuted communication satellite resource utilization plans.

[0067] After determining the adjusted plan of the target user center, it is necessary to determine whether the task period of the adjusted plan still overlaps with the task period of the remaining plans in the plan to be merged (unadjusted plans in the plan to be merged). If there is no overlap, delete the target merged plan and re-plan the resources according to all the current unexecuted communication satellite resource utilization plans. That is, return to step S104 above, re-determine the plan to be merged from multiple unexecuted communication satellite resource utilization plans, and when it is determined that the plan can be merged, re-merge the plans and feed back the updated plans to each relevant user center.

[0068] If the task period of the adjusted plan overlaps with the task period of the remaining plan in the plan to be merged, the plan to be merged is updated, specifically, the task period of the target communication satellite resource usage plan is updated, and then it is determined whether there is a resource conflict between the updated plan to be merged and other unexecuted communication satellite resource usage plans, so as to update the communication satellite resource usage plan of the relevant user center according to the resource conflict detection result. The subsequent processing methods with and without resource conflicts have been described in detail above. Please refer to the above for details, which will not be repeated here.

[0069] In an optional implementation manner, after obtaining the target merging plan, the method of the present invention further comprises the following steps:

[0070] Step S301, receiving a request for deleting a target communication satellite resource use plan of the target user center sent by the target user center; wherein the target user center represents any user center among several user centers participating in the plan merging.

[0071] Step S302, when it is determined that the time difference between the sending time of the deletion request and the start time of the target merge plan is greater than a preset time threshold, the target merge plan is deleted, and the resources of the communication satellite system are replanned based on all unexecuted communication satellite resource utilization plans.

[0072] Specifically, for the merged plan, if one of the user centers participating in the plan merger wants to delete its plan, the user center needs to submit a deletion request some time before the start of the target merged plan, and the request will be accepted, otherwise the communication satellite system will refuse to delete the plan.

[0073] After deleting the target merge plan, the resources of the communication satellite system are re-planned according to all the current communication satellite resource utilization plans that have not yet been executed, that is, returning to step S104 above, re-determining the plans to be merged from multiple unexecuted communication satellite resource utilization plans, and when it is determined that they can be merged, re-merging the plans and feeding back the updated plans to each relevant user center.
