[0027] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0028] The on-orbit servicing satellite mission planning engine is a system used to optimize and manage on-orbit servicing satellite missions. It integrates multiple technical means to ensure that the on-orbit servicing satellite can complete its scheduled missions efficiently and safely during operation.

[0029] Figure 1It is the overall framework of the generalized scheduling engine in related technologies. Figure 1 As shown, the satellite mission planning engine proposed in the existing scheme consists of a generalized modeling module for satellite mission scheduling, a generalized solution module for routine scheduling, and a generalized solution module for emergency scheduling. The generalized modeling module for satellite mission scheduling is responsible for modeling the satellite mission planning problem, abstracting the mission to be planned, available satellites, ground station resources, mission planning constraints, and the payoff function to form a multi-constraint optimization mathematical problem. The generalized solution module for routine scheduling is responsible for solving the multi-constraint optimization mathematical problem based on a general algorithm framework of adaptive parallel evolution and the mathematical tools of algorithm pools and operator pools for routine mission planning. The generalized solution module for emergency scheduling is responsible for developing rolling emergency mission planning solutions based on a general algorithm framework of distributed real-time rolling and a multi-agent negotiation mechanism for emergency mission planning. In the satellite mission planning engine, by sequentially calling the generalized modeling module for satellite mission scheduling, the generalized solution module for routine scheduling, and the generalized solution module for emergency scheduling, the entire satellite mission planning process, from requirement acquisition, model construction, optimization calculation, to solution generation, is implemented.

[0030] The technical shortcomings of existing solutions primarily manifest in the following three areas: 1) Existing methods rigidly define the satellite mission planning process, resulting in limited flexibility. These methods establish a generalized framework of "generalized modeling" and "generalized solution." These methods build mathematical models based on the mission model, resource model, constraint model, and benefit model, and then employ various optimization methods to develop optimized strategies. On-orbit servicing satellite mission planning is characterized by a wide variety of types and complex application scenarios. Using existing methods for on-orbit servicing satellite mission planning, it is difficult to flexibly schedule computational modules based on dynamic mission requirements and rapidly establish a mission planning computational process. 2) Existing solutions have complex module construction and poor maintainability. Existing solutions abstract the generalized modeling and solution modules required for satellite mission planning, internally designing modeling units, operator pools, and algorithm pools. This design results in a large number of modules, requiring complete module modification and testing for algorithm upgrades. This approach struggles to meet the requirements for frequent algorithm updates and high maintainability for on-orbit servicing satellite mission planning. 3) Existing solutions only support deployment on a single computing node, making distributed implementation difficult. The calculation process of on-orbit servicing satellite mission planning is complex and requires a large amount of computation. When using existing solutions for mission planning, it is impossible to take advantage of the performance advantages of high-performance computing server clusters. It is necessary to further build a distributed parallel computing mechanism to improve the computational efficiency of the mission planning engine.

[0031] Based on the technical defects of the existing solutions, the present invention proposes an on-orbit service satellite mission planning engine system. Figure 2The overall framework diagram of the on-orbit servicing satellite mission planning engine system provided by the present invention is as follows: Figure 2 As shown, the present invention adopts the technical approach of task planning microservices. The task planning engine system mainly includes a task planning microservice registration center module, a computing resource virtualization module, a computing resource scheduling module, a task planning microservice dynamic aggregation module, a task planning process status tracking module, and various types of on-orbit service satellite task planning microservice collection modules.

[0032] The mission planning microservice registration center module is used to register and manage the permissions of various on-orbit service satellite mission planning microservices; the computing resource virtualization module is used to register the computing server cluster and virtualize the computing resources to form a resource pool, providing basic hardware computing resources for the mission planning microservice; the computing resource scheduling module is used to schedule the computing resources of the computing server cluster according to the computing resource usage requirements of various mission planning microservices; the mission planning microservice dynamic aggregation module is used to create, start, run and track mission planning process instances, track process status information, and control the execution process; the mission planning process status tracking module is used to receive the status information of each mission planning microservice, determine the running status of the mission planning microservice and the running status of the mission planning process, and issue alarm prompts for abnormal status; the mission planning microservice collection module is used to provide computing services for the specific applications of on-orbit service satellite mission planning.

[0033] Figure 3 The architecture diagram of the on-orbit service satellite mission planning engine system provided by the present invention is as follows: Figure 3 As shown in the figure, the on-orbit service satellite mission planning engine adopts a three-layer architecture of "interactive presentation layer-data persistence layer-business logic layer".

[0034] The first layer is the data interactive presentation layer, which provides an interactive operation interface for administrators or users. It is mainly used for users to input registration information of task planning microservices, process modeling information, configure scheduling strategies, and trigger manual intervention instructions, while monitoring the execution process of task planning process instances; the second layer is the business logic layer, which is the core part of this configuration item. It consists of a series of business logic objects, handles various task planning function requests, and implements specific computing resource access and process instance scheduling and execution functions, including microservice registration center, computing resource scheduling, microservice process construction and driving, and microservice entities; the second layer is the data persistence layer, which is used to uniformly store and manage information such as various task planning microservices, processes, resources, instances, etc., providing data support for the interactive presentation layer.

[0035] Figure 4 The workflow diagram of the on-orbit service satellite mission planning engine system provided by the present invention is as follows: Figure 4 shown.

[0036] The workflow of the on-orbit servicing satellite mission planning engine is described as follows: (1) Users register available computing server resources into a computing “resource pool”; (2) The computing “resource pool” is managed by resource monitoring and provides resource status query services; (3) The task planning engine receives the task planning microservice computing resource scheduling order and parses the content of the task planning microservice computing resource scheduling order; (4) Query the resource status service for available computing resources; (5) Dynamically allocate server computing resources according to the microservice computing execution requirements of task planning; (6) Using the allocated server computing resources, schedule the mission planning microservice to execute the mission planning business of the on-orbit service satellite; (7) Feedback the business process execution status and task planning microservice status to resource status monitoring in real time.

[0037] The task planning microservice registration center module is used to receive the registration information of the task planning microservice and store the registration information in the database. The task planning microservice can be simply referred to as the microservice; the registration information of the task planning microservice can be implemented in XML (Extensible Markup Language), that is, it can be provided and configured in XML format. The registration content includes basic information, resource requirement information and parameter template information.

[0038] The basic information includes the microservice ID, microservice name, publisher, version description, version number, microservice description, etc. The microservice ID is the unique identifier of the microservice and cannot be changed after it is determined. It cannot be repeated with the IDs of other microservices. Resource requirement information includes resource requirement parameters such as the maximum number of startups, the minimum number of startups, the number of CPUs to be allocated, the number of GPUs to be allocated, the amount of memory, and scheduling priority. Resource requirement parameters are logical-level resource configurations, and computing resources are allocated based on these resource requirement parameters during microservice scheduling. The parameter template information includes the input parameter list, output parameter list and processing parameter list. The parameter template of the microservice is defined according to the specific functional requirements of the microservice. The parameter templates of different microservices can be customized.

[0039] Figure 5 This is a schematic diagram of the registration process of the mission planning microservice in the on-orbit service satellite mission planning engine system provided by the present invention. Figure 5 As shown, the task planning microservice registration process includes: 1) Add a new registered microservice and fill in the basic information of the microservice; the user fills in the basic information of the microservice, including the microservice identifier, name, publisher, version description, version number and microservice description. The on-orbit service satellite mission planning engine system verifies the uniqueness of the microservice identifier to ensure that it is not duplicated with existing microservice identifiers; 2) Edit the computing resource requirements of microservices. Users fill in resource requirement information based on the functional requirements of the microservices, including the maximum number of startups, the minimum number of startups, the number of CPUs, the number of GPUs, the amount of memory, and the scheduling priority. The on-orbit service satellite mission planning engine system generates a logical resource configuration template based on the resource requirement information. 3) Fill in the microservice calculation parameter template; users define the input parameter list, output parameter list, and processing parameter list based on the specific functional requirements of the microservice. The on-orbit servicing satellite mission planning engine system supports personalized customization, and the parameter templates of different microservices can be flexibly configured according to needs; 4) Store various parameter information of microservices in the database and publish module entities; the on-orbit service satellite mission planning engine system stores the basic information, resource requirement information and parameter template information of microservices in the database.

[0040] The computing resource virtualization module provides a unified computing resource management interface for the task planning engine, shielding against the influence of different computing servers and operating systems to form a virtualized "resource pool." Access resources include CPU, memory, network interface cards, and storage. It supports monitoring the status of server computing resources, establishes a connection between actual resources and virtualized server computing resources, and completes the registration and pooling management of server computing resources.

[0041] Figure 6 The flowchart of computing resource virtualization in the on-orbit service satellite mission planning engine system provided by the present invention is as follows. Figure 6 As shown in the figure, the computing resource virtualization module completes the access and pooling of various server computing resources. The specific process is as follows: 1) During the process startup phase, server computing resources are connected to the task planning engine; 2) The task planning engine obtains computing resource information, determines the resource virtualization type based on the computing resource information, and builds a dedicated virtualization model for it; 3) Register resources as virtualized resource nodes based on computing resource information, and configure information such as whether the resource nodes are enabled, grouped, and have call priority. 4) After resource virtualization configuration, the virtualized resource nodes will be connected to the virtualized "resource pool" and managed uniformly by the virtualized "resource pool".

[0042] The computing resource scheduling module matches the scheduling strategy of the task planning microservice according to the scheduling strategy configured by the task planning microservice and the computing resource requirements of the task planning, allocates the computing resource requirements of the task planning microservice to specific computing nodes for scheduling execution, and can perform computing queue scheduling management according to time sequence or priority.

[0043] Figure 7 The flowchart of computing resource scheduling in the on-orbit service satellite mission planning engine system provided by the present invention is as follows. Figure 7 As shown in the figure, the computing resource scheduling module monitors the computing resource requirements of the external task planning microservice, parses the computing resource requirements, obtains the corresponding task planning microservice strategy and computing resource requirements, and matches the first computing node that meets the computing resource requirements of the task planning microservice according to the scheduling strategy. The specific process is as follows: 1) Monitor the computing resource requirements of task planning microservices and analyze the computing resource requirements; 2) Build a computing resource demand queue for the task planning microservice, sort the computing resource demand queue according to the scheduling strategy, and sort it by priority; the scheduling strategy includes time sequence and priority; 3) Based on the scheduling strategy and computing resource requirements, match the computing nodes that meet the computing resource requirements of the task planning microservice; 4) Allocate the task planning microservice calculation to the corresponding computing node for execution.

[0044] The Task Planning microservice dynamic aggregation module is the core of the Task Planning engine and the actual executor of Task Planning process instances. It is responsible for the entire lifecycle management of Task Planning process instances and supports parallel processing based on automated operations, including process initiation, scheduling, tracking, and closed-loop operations. The Task Planning microservice dynamic aggregation module simultaneously maintains the execution status of multiple Task Planning process instances and is the core driver of the Task Planning engine.

[0045] Figure 8 The flowchart of the dynamic aggregation of task planning microservices in the on-orbit service satellite task planning engine system provided by the present invention is as follows. Figure 8 As shown in the figure, the mission planning microservice dynamically aggregates the topological relationship of the on-orbit service satellite mission planning process, and executes and runs the scheduling process according to the logical dependencies. The specific process is as follows: 1) Start the mission planning calculation process, analyze the attributes of the in-orbit service satellite and associate it with the parent process if the mission planning calculation process is a sub-process; 2) Analyze the topological dependencies of the task planning calculation process and generate a task planning process topology diagram; the task planning process topology diagram is used to clarify the execution order and logical dependencies of each task planning microservice; 3) Determine whether there are available computing nodes that can execute the task planning calculation process and perform node attribute judgment; 4) When a static computing node is needed, a static computing order is generated and submitted to the computing resource scheduling module to apply for static computing resources. When a dynamic computing node is needed, a dynamic computing resource is applied to the computing resource scheduling module. Static computing nodes are used to allocate fixed server resources, and dynamic computing nodes are used to dynamically allocate computing resources.

[0046] The Task Planning Process Status Tracking module captures and analyzes the execution status of the Task Planning microservice, including the start and end of the Task Planning microservice's computation. This serves as the foundation for process scheduling and the lifecycle management of Task Planning process instances. It tracks and analyzes the running status of the Task Planning microservice, obtaining the computation start time, execution node, end time, and exit code. The exit code determines the execution result of the Task Planning microservice, classifying it as either success or failure. It also sets the execution status of the corresponding processing node in the corresponding flowchart, including creation status, queue status, running status, success status, and failure status.

[0047] Figure 9 The present invention provides a flow chart of the task planning process tracking and monitoring in the on-orbit service satellite task planning engine system. Figure 9 As shown, the task planning process status tracking module monitors the computing status of the task planning microservice, parses information such as the start time, computing node, and end time, and sets the flowchart processing node to the running state. The specific process is as follows: 1) Start the tracking and monitoring function of the mission planning process to track the calculation process status of the on-orbit servicing satellite mission planning and determine whether it is in the start state or the end state; 2) When the calculation state is in the start state, parse and obtain the start time and calculation node information, and set the corresponding processing node in the process monitoring diagram to the running state; 3) When the calculation status is in the end state, the end time and exit code information are parsed and obtained. The execution result is determined based on the exit code, and the corresponding processing node in the process monitoring diagram is set to a success state or a failure state. The exit code is used to determine the execution result of the task planning microservice. 4) Update the status display of the task planning process instance based on the topological dependency of the process to which the node belongs and the topological relationship of the sub-process or parent process.

[0048] The task planning microservice collection module is also used to register various task planning algorithms in the form of task planning microservices to the task planning microservice registration center; according to task planning requirements, schedule the microservices in the task planning microservice collection and build different types of task planning processes; support the expansion and upgrade of task planning microservices, develop new microservices according to task requirements and register them to the task planning microservice registration center; perform specific task planning calculations by scheduling and combining different task planning microservices.

[0049] The mission planning microservices module is the primary component for executing on-orbit servicing satellite mission planning. Various algorithms used by on-orbit servicing satellites are registered as microservices with the mission planning microservices registry. These algorithms support dynamic scheduling by the mission planning engine, enabling the construction of different types of on-orbit servicing satellite mission planning processes. The mission planning microservices include, but are not limited to, demand generation microservices, orbit prediction microservices, window calculation microservices, orbit control strategy calculation microservices, attitude strategy calculation microservices, constraint optimization solution microservices, resource management microservices, and payload control microservices. The mission planning microservices can be expanded and upgraded to accommodate different types of on-orbit servicing satellite mission planning.

[0050] The on-orbit service satellite mission planning engine system and method provided by the present invention registers and manages the permissions of various on-orbit service satellite mission planning microservices through a mission planning microservice registration center module, implements various algorithm modules required for on-orbit service satellite mission planning in the form of mission planning microservices, and then flexibly assembles various mission planning microservices through a mission planning microservice dynamic aggregation module to establish various on-orbit service satellite mission processes, making the task planning process construction of the on-orbit service satellite mission planning engine more flexible; the on-orbit service satellite mission planning microservice collection constructed by the present invention, the various microservices in the collection can be independently operated, independently upgraded, and reused, and can be quickly integrated with other microservices under the condition of meeting interface consistency, effectively improving the maintainability of the on-orbit service satellite mission planning engine.

[0051] In response to the problem that existing methods only support deployment on a single computing node and are difficult to achieve distributed implementation, the present invention virtualizes the computing resources of a high-performance computing server cluster to form a virtual "resource pool" and dynamically schedules computing service resources according to resource scheduling rules and the computing requirements of task planning microservices, thereby meeting the computing requirements of in-orbit service satellite mission planning and achieving load balancing of each computing node in the computing server cluster.

[0052] Figure 10 The flowchart of the on-orbit servicing satellite mission planning engine method provided by the present invention is as follows. Figure 10As shown, an on-orbit service satellite mission planning engine method implemented based on the on-orbit service satellite mission planning engine system as described above includes: step 101, registering and managing permissions for various on-orbit service satellite mission planning microservices; Step 102: Register the computing server cluster and virtualize computing resources to form a resource pool to provide basic hardware computing resources for the task planning microservice; Step 103: Scheduling computing resources of the computing server cluster according to the usage requirements of the computing resources by various task planning microservices; Step 104: Create, start, run, and track the task planning process instance, track process status information, and control the execution process; Step 105: Receive status information of each of the task planning microservices, determine the running status of the task planning microservice and the running status of the task planning process, and issue an alarm for abnormal status; Step 106: Provide computing services for specific applications of the on-orbit servicing satellite mission planning.
