Description

[0002] With the development of my country's space industry, the TT&C network continues to expand, and the number of satellites in orbit continues to increase. The allocation and scheduling of TT&C resources has become increasingly important in the operation and management of the network. Due to the numerous uncertainties inherent in spacecraft operations, such as shifting satellite TT&C requirements, emergency response, and changes in payload data injection timing, the TT&C system must rapidly complete TT&C mission planning, resource allocation, space link establishment, and remote control command processing and transmission upon receiving new mission requirements. As a key component of TT&C services, the automation of TT&C resource scheduling plays a crucial role in shortening response times and improving TT&C service capabilities.

[0043] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0044] In addition, the accompanying drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. Identical reference numerals in the figures denote identical or similar parts, and thus repetitive descriptions thereof will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities that do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0045] This example implementation first provides a method for automatic hierarchical scheduling of aerospace measurement and control resources. Figure 1 As shown in , the method may include the following steps:

[0046] Step S101: obtaining an application for a measurement and control task and analyzing the measurement and control task;

[0047] Step S102: stratifying the measurement and control resources according to the status information associated with the measurement and control tasks;

[0048] Step S103: planning the order of searching and applying for measurement and control resources according to the preference information of the measurement and control tasks and according to the hierarchy;

[0049] Step S104: Search or apply for measurement and control resources according to the planned order.

[0050] It should be understood that during the normal execution of the measurement and control task, due to various unexpected conditions, the measurement and control task cannot be executed normally. Therefore, it is necessary to perform emergency resource application for the measurement and control task, that is, the application task of the measurement and control task.

[0051] It's also important to understand that the space-based and ground-based resources within the measurement and control (MTC) system belong to two different systems. This scheduling method coordinates the planning of both space-based and ground-based resources. This scheduling method can be applied to either space-based or ground-based systems. When applied to a space-based system, the user's MTC task involves submitting an application to the space-based system. When this scheduling method is applied, once a space-based resource is found, no additional application is required; the space-based system directly allocates it. When a ground-based resource is found, an additional application must be submitted to the ground-based system. If the application is successful, feedback is provided to the user. Similarly, when applied to a ground-based system, the user's MTC task involves submitting an application to the ground-based system. When this scheduling method is applied, once a ground-based resource is found, no additional application is required; the ground-based system directly allocates it. When a space-based resource is found, an additional application must be submitted to the space-based system. If the application is successful, feedback is provided to the user. Similarly, if the space-based and ground-based systems are combined, or if the user has the authority to allocate resources to both space-based and ground-based systems, this scheduling method can be applied on this basis. Regardless of whether the space-based or ground-based resources are found, the found measurement and control resources can be directly allocated to the user's measurement and control tasks without the need for an additional application process. Similarly, this scheduling method can also be used independently. On this basis, regardless of whether the space-based or ground-based resources are found, the application process must be executed with the corresponding space-based or ground-based system.

[0052] It's also important to understand that measurement and control resources can be stratified based on the degree of disruption to existing scheduling plans. For example, they can be stratified into four tiers: planned resources, idle resources, transferable resources, and preemptible resources. Alternatively, they can be stratified into three tiers: planned resources, idle resources, and visible resources. Alternatively, they can be stratified into two tiers: planned resources and unplanned resources. However, the first tier is always the one with the least disruption, such as planned resources. During searches and applications, the first tier with the least disruption is prioritized, followed by the next tiers with higher disruptions. For example, based on the measurement and control requirements of an emergency mission, the availability of space-based resources is prioritized based on the availability and preemptibility criteria. If space-based resources are no longer sufficient, ground-based resources are then used to determine whether they can meet the requirements, based on the availability, transferability, and preemptibility criteria.

[0053] It is also important to understand that applications for space-based resources can be made to the relay, and applications for ground-based resources can be made directly to the device.

[0054] Through the above method, by stratifying the monitored resources according to the planned status and combining the resource preference information, it is possible to meet the measurement and control needs of important emergency tasks while minimizing the disturbance to the existing scheduling plan as much as possible, and quickly and automatically process dynamic emergency application needs.

[0055] Below, we will refer to Figures 1 to 9 Each step of the above method in this exemplary embodiment is described in more detail.

[0056] In one embodiment, reference Figure 2 As shown, step S102 may include the following steps:

[0057] Step S201: stratify the measurement and control resources according to the status of the equipment within the application period of the measurement and control task.

[0058] It should be understood that the measurement and control resource equipment includes various measurement and control satellites and ground fixed base stations and mobile base stations, and will be in different working states during the application period of the measurement and control task.

[0059] In one embodiment, measurement and control resources include space-based resources and ground-based resources; space-based resources and ground-based resources are divided into four layers and eight categories based on planned resources, idle resources, transferable resources, and preemptible resources. It should be understood that the four layers and eight categories are resource stratification based on the planned status of the equipment during the application period. In combination with the different space-based resources, they are divided into space-based planned, ground-based planned, space-based idle, ground-based idle, space-based transferable, ground-based transferable, space-based preemptible, and ground-based preemptible. Among them, planned resources refer to space-based measurement and control resources that have been scheduled for the measurement and control task during the application period; idle resources refer to space-based measurement and control resources that are idle during the application period; transferable resources refer to space-based resources that are occupied by other satellites during the application period, but can be transferred to other devices by the satellite occupying the device; preemptible resources refer to space-based resources that are occupied by other satellites during the application period, and cannot be transferred to other devices by the satellite occupying the device, but can be preempted.

[0060] In one embodiment, reference Figure 3 As shown, step S103 may include the following steps:

[0061] Step S301: planning the order of searching and applying for space-based resources and ground-based resources at each layer according to the usage preference of the measurement and control tasks between space-based resources and ground-based resources.

[0062] It's important to understand that different TT&C missions have different preferences for using space-based or ground-based resources. For example, for low-Earth orbit missions, prioritizing space-based resources facilitates earlier TT&C. For some satellites, a preference for ground-based resources allows for an automated scheduling process that prioritizes ground-based resources. Specifically, the system searches for scheduled space-based TT&C resources for the satellite, then prioritizes planned space-based or ground-based resources based on the user's resource usage preferences. Furthermore, the overall search process can be planned based on the user's TT&C resource preferences. For example, if a user specifies space-based resources as the top priority, the system will only search for ground-based resources after searching for planned, idle, transferable, and preemptible space resources and finding no space-based resources. Similarly, if a user specifies ground-based resources as the top priority, the system will only search for space-based resources after searching for planned, idle, transferable, and preemptible ground resources and finding no ground-based resources. This allows for more flexible scheduling of search or application orders based on the TT&C mission's usage preferences.

[0063] In one embodiment, step S103 may include the following steps:

[0064] Step S302: when multiple idle resources are found according to the application period of the measurement and control task, the application order of the multiple idle resources is planned according to the start time of the idle resources and in descending order.

[0065] It should be understood that after searching for idle resources within the application period, when multiple idle resources exist, the resource with an earlier start time is preferably used as the resource applied for by the satellite.

[0066] In one embodiment, step S103 may include the following steps:

[0067] Step S303: When multiple transferable resources are found, the application order of the multiple transferable resources is planned according to the number of transfers of the transferable resources.

[0068] It's important to understand that applying for transferable resources requires transferring the satellites occupying that equipment to other equipment. Therefore, fewer transfers mean less disruption to existing scheduling plans. Therefore, priority should be given to applying for transferable resources with the fewest transfers. Factors such as the impact on other missions can also be considered for optimal selection.

[0069] In one embodiment, step S103 may include the following steps:

[0070] Step S304: when multiple preemptible resources are found, the application order of the multiple preemptible resources is planned according to the impact of the preemptible resources on other measurement and control tasks.

[0071] It should be understood that the importance of other measurement and control tasks, or the impact of currently available resources on other measurement and control tasks, can be considered. For example, some measurement and control tasks use two satellites for measurement and control at the same time, and temporarily using one satellite for measurement and control will not have a big impact on the original measurement and control tasks.

[0072] In one embodiment, reference Figure 4 As shown, step S103 may include the following steps:

[0073] Step S305: searching for measurement and control resources in the order of four-layer and eight-category planning, and applying for the found measurement and control resources after each search is completed.

[0074] It's important to understand that, based on the four tiers and eight categories of resources (space-based planned, ground-based planned, space-based idle, ground-based idle, space-based transferable, ground-based transferable, space-based preemptible, and ground-based preemptible), once a search is completed for a category, applications will begin based on the resources found within that category. In other words, planning primarily focuses on the order of searches, while the order of applications primarily follows the order of searches.

[0075] In one embodiment, reference Figure 5 As shown, step S103 may include the following steps:

[0076] Step S306: Search for measurement and control resources of all layers, and plan the application order of the found measurement and control resources according to the preference information of the layers and measurement and control tasks.

[0077] It is important to understand that all available measurement and control resources are searched first, and then each of the found measurement and control resources is sorted and applied for. In other words, there is no need to plan the search order, but directly plan the application order.

[0078] In one embodiment, reference Figure 6 As shown, step S104 may include the following steps:

[0079] Step S401: When the application of any sequence is successful, the application task of the measurement and control task is determined to be completed, and the search or application of the subsequent sequence is terminated.

[0080] It's important to understand that each time you apply for measurement and control resources, you'll be checked to see if the request is successful. If it is, the emergency task application is successful. If it is unsuccessful, you'll continue searching or applying. Furthermore, when searching for planned resources that meet your needs, if you find any, the emergency task application is considered successful, and no additional application is required.

[0081] It should be noted that although the steps of the method disclosed herein are depicted in a particular order in the accompanying drawings, this does not require or imply that the steps must be performed in that particular order, or that all steps must be performed to achieve the desired result. Additionally or alternatively, certain steps may be omitted, multiple steps may be combined into a single step, and / or a single step may be decomposed into multiple steps. Furthermore, it is readily understood that these steps may be executed synchronously or asynchronously, for example, in multiple modules / processes / threads.

[0082] In the following, in combination with the above embodiments, more specific embodiments will be presented for further detailed description.

[0083] Specific embodiment 1, refer to Figure 7 As shown:

[0084] Considering the wide coverage of space-based tracking and control resources, for low-orbit missions, giving priority to space-based resources is more conducive to the early implementation of tracking and control. At the same time, in order to allow satellite users to obtain as many resources as possible through a single application, applicants can provide multiple application arcs (usually three arcs). The space-based priority process includes the following steps:

[0085] a. Receive emergency applications from satellite users and enter the planned resource application process;

[0086] Find the allocated space-based program arc that meets the requirements. If there are available resources, the emergency task application is successful. If not, find the allocated ground-based program arc that meets the requirements.

[0087] If there is an allocated ground-based planning arc, the emergency mission application is successful. If not, it enters the space-based resource application process.

[0088] b. During the space-based resource application process, search for idle space-based resources;

[0089] If there are idle space-based resources, apply for idle resources from the relay. If the application is successful, the emergency task application is successful. If the application is unsuccessful, the process of applying for ground-based resources will be transferred.

[0090] If no space-based idle resources are found, then search for space-based visible resources. If there are visible resources, apply to the relay for visible resources. If the relay application is successful, the emergency task application is successful. If the relay application is unsuccessful, it will enter the ground-based application process.

[0091] c. In the foundation application process, first apply for idle foundation resources. If the foundation resource application is successful, the emergency task application is successful. If the foundation resource application is unsuccessful, then apply for the foundation transferable arc segment (that is, after the original task performed by the measurement and control equipment is replaced with the emergency task, other idle resources can be found for the original task).

[0092] If the application is successful, the emergency task application is successful. If the application is unsuccessful, the application foundation can preempt resources (that is, after the original task performed by the measurement and control equipment is replaced with the emergency task, no other idle resources can be found for the original task).

[0093] If the application is successful and the resources can be preempted, the emergency task application is successful. If the application is unsuccessful, the application fails and the process ends.

[0094] Specific embodiment 2, refer to Figure 8 As shown:

[0095] For some satellites, there is a preference for using ground-based resources. An automated scheduling process that prioritizes the use of ground-based resources can be used. Allocated ground-based resources are searched first in the allocated plan, and then the ground-based resources are searched in the order of free, transferable, and preemptible. If no ground-based resources are found, they are applied for in the order of free and visible space-based resources. The specific steps are as follows:

[0096] a. Receive emergency applications from satellite users and enter the planned resource application process;

[0097] First, search for an allocated ground-based program arc that meets the requirements. If there are available resources, the emergency task application is successful. If not, search for an allocated space-based program arc that meets the requirements.

[0098] If there is an allocated space-based program arc, the emergency mission application is successful. If not, it enters the ground-based resource application process.

[0099] b. In the foundation application process, first apply for idle foundation resources. If the foundation resource application is successful, the emergency task application is successful. If the foundation resource application is unsuccessful, then apply for the foundation transferable arc segment (that is, after the original task performed by the measurement and control equipment is replaced with the emergency task, other idle resources can be found for the original task).

[0100] If the application is successful for the transferable arc segment of the foundation, the emergency task application is successful. If the application is unsuccessful for the transferable resources of the foundation, the foundation preemptible resources are applied for (that is, after the original task performed by the measurement and control equipment is replaced with the emergency task, no other idle resources can be found for the original task to be executed);

[0101] If the application for ground-based preemptible resources is successful, the emergency task application is successful. If the application for ground-based preemptible resources is unsuccessful, the application process for space-based resources will be entered.

[0102] c. In the space-based resource application process, first search for idle space-based resources;

[0103] If there are idle space-based resources, the idle resources will be applied to the relay. If the relay idle resource application is successful, the emergency task application is successful. If the relay idle resource application is unsuccessful, the ground-based resource application process will be entered.

[0104] If there are no idle space-based resources, search for visible space-based resources. If there are visible resources, apply to the relay for visible resources. If the relay visible resource application is successful, the emergency task application is successful. If the relay visible resource application is unsuccessful, the application fails and the process ends.

[0105] Specific embodiment three, refer to Figure 9 As shown:

[0106] For managers of space-based measurement and control resources, they often do not want new applications to impact existing plans. Taking into account user resource usage preferences, they can design a mixed scheduling process for space-based resources based on a hierarchical design concept of planned, idle, transferable, and preemptible resources.

[0107] a. Receive emergency applications from satellite users and enter the planned resource application process;

[0108] First, search for an allocated space-based program arc that meets the requirements. If there are available resources, the emergency task application is successful. If not, search for an allocated ground-based program arc that meets the requirements.

[0109] If there is an allocated ground-based planning arc, the emergency mission application is successful. If not, it enters the space-based resource application process.

[0110] b. In the space-based resource application process, first search for idle space-based resources;

[0111] If there are idle space-based resources, apply for idle resources from the relay. If the application for idle space-based resources is successful, the emergency task application is successful. If the application for idle space-based resources is unsuccessful, the process of applying for ground-based resources will be transferred.

[0112] If no space-based idle resources are found, then the ground-based idle resources will be searched. If there are ground-based idle resources, the emergency task application will be successful. If not, then the space-based visible resources will be searched. If there are visible resources, then the visible resources will be applied to the relay. If the space-based visible resource application is successful, the emergency task application will be successful. If the space-based visible resource application is unsuccessful, then the application process in the ground-based application process will be transferred. If there are no visible resources, then the transfer process in the ground-based application process will be transferred.

[0113] c. In the foundation application process, first apply for idle foundation resources. If the application is successful, the emergency task application is successful. If the application is unsuccessful, apply for the transferable arc segment of the foundation (that is, after the original task performed by the measurement and control equipment is replaced with the emergency task, other idle resources can be found for the original task).

[0114] If the application is successful, the emergency task application is successful. If the application is unsuccessful, the application foundation can preempt resources (that is, after the original task performed by the measurement and control equipment is replaced with the emergency task, no other idle resources can be found for the original task).

[0115] If the application is successful and the resources can be preempted, the emergency task application is successful. If the application is unsuccessful, the application fails and the process ends.
