Step S102, receiving an emergency task request.
Step S104, generating a task list to be planned according to the emergency task type corresponding to the emergency task request.
In one embodiment, scheduled tasks are stored in a scheduled task list and unscheduled tasks are stored in a to-be-scheduled task list. In addition, it is also possible to update all tasks to be processed and calculate the maximum time to move back for all planned tasks.
The emergency task types corresponding to the emergency task requests comprise platform emergency tasks and load emergency tasks, and the task list to be planned comprises newly received platform emergency tasks and load emergency tasks.
And step S106, triggering a sliding task planning task, and acquiring a current planned task list corresponding to the task list to be planned in the process of executing the sliding task planning task.
In one embodiment, for the current task, it is determined whether the task can be inserted using a sliding operation, that is, whether the time for which sliding is actually required is less than the maximum backward movement time.
In one example, if it is possible to insert, it is determined whether the task conflicts with another task, and a priority comparison is made with the conflicting task. If the current task priority is higher than the conflict task, the imaging start time of the corresponding conflict task is slid backwards to the time when the imaging start time of the corresponding conflict task is actually required to be slid, and the current task is inserted.
In one example, if no insertion is possible, the current task is slid to the next window.
The current planned task list includes a plurality of task requests, wherein part of task requests may be executed by the satellite system, and part of task requests may not be executed by the satellite system.
Step S108, determining a target task set to be planned according to the sliding window of the sliding task planning task from the unexecuted task request and the emergency task request in the current planned task list.
In one embodiment, the unexecuted task requests and the emergency task requests in the current planned task can be summarized, classified and decomposed to generate a target task set to be planned. Specifically, the updated task list to be planned can be optimized and recombined, i.e. the tasks in the list are classified, decomposed and combined to generate a target task set for planning.
Wherein the priority of the emergency task request is higher than the priority of the unexecuted task request. In one embodiment, during each scheduling, only the emergency task in the current sliding window is planned, and as the scheduling time advances, new emergency task requests are continuously added, and the emergency task requests which complete the scheduling are gradually deleted, so that the updating of the sliding window is realized.
Step S110, a target planning scheme is determined based on the target task set to be planned, so that tasks corresponding to the target task set are executed according to the target planning scheme.
In one embodiment, satellite resources and data transmission resources are configured according to a task set in a sliding window, resource conflict and task constraint conditions are comprehensively considered, emergency task planning is completed, and a task planning scheme is generated.
The new mission planning scheme includes not only newly received emergency mission, but also load and platform mission not executed in the previous planning scheme. The output mode of the task planning scheme is one or more of an uploading task list, a returning task list and an observing task list.
The process of executing the task is as follows: the uploading operation can be executed aiming at the task to be observed contained in the target planning scheme so as to send the task to be observed to a satellite system, so that the satellite system executes the task to be observed according to the planned observation mode and the planned observation time to obtain data transmission data corresponding to the task; the data transmission data is the original observation data, can be directly provided for users, and can be distributed to the users after being processed.

On the basis, the embodiment of the invention provides a specific implementation mode of an emergency task response method.
In one embodiment, when the step of determining the task list to be planned according to the emergency task type corresponding to the emergency task request is executed, if the emergency task type corresponding to the emergency task request is a platform emergency task, determining the list to be annotated, specifically, if the platform task is visible for a circle, annotating the instruction and receiving the telemetry are performed simultaneously, and satellite states can be monitored while the instruction is executed; if the platform task is executed in invisible circles, a delay instruction is sent; and if the emergency task type corresponding to the emergency task request is a load emergency task, determining that the task list to be planned comprises a list to be uploaded, a list to be returned and a list to be observed.
The platform emergency task comprises one or more of a satellite component abnormal task, a satellite working mode abnormal task and a satellite collision early warning response task; the load emergency tasks include one or more of emergency demand application tasks, heavy natural disaster tasks, and sudden tasks.
In one embodiment, if the unexecuted task request in the task list to be planned has already performed a uploading operation, that is, the emergency task is issued later than the measurement and control time point, a task triggering mode may be adopted, and the emergency scheduling algorithm may be immediately started to dynamically adjust the existing scheme; if a planning scheme exists when an emergency task is issued and an instruction is not injected, a periodic triggering mode is adopted for triggering, and the existing scheme is dynamically adjusted.
In practical application, when the resource management side does not receive an emergency task request, a conventional task scheduling algorithm is adopted to periodically generate a conventional task week plan; when the server receives emergency task requests proposed by a plurality of users, a sliding window planning and scheduling technology is adopted, namely, a mixed triggering mode combining periodic triggering and emergency task triggering is adopted for imaging observation resource dynamic task planning under the emergency normalization condition. If the planning scheme exists when the emergency task is issued and the instruction is not injected, re-planning or dynamic scheme adjustment is carried out; if the command is already uploaded, namely the emergency task is issued later relative to the measurement and control time point, a task triggering mode can be adopted at this time, and an emergency scheduling algorithm can be immediately started to dynamically adjust the existing scheme.
According to the distribution condition of measurement and control resources, the emergency scheduling algorithm adopts a sliding type dynamic scheduling method based on the measurement and control window as a period, and the basic idea is that emergency tasks are divided into task sets with a certain degree of overlap according to the arrival time, but the task sets are continuously advanced along with the scheduling time, and when each scheduling is performed, only the emergency tasks in the current sliding window are planned. With the advance of the scheduling time, new emergency tasks are continuously added, and the scheduled emergency tasks are gradually deleted, so that the updating of the sliding window is realized.
The sliding task scheduling is carried out on various types of satellite sensing resources according to a proper scheduling period, the scheduling period mainly depends on measurement and control opportunities, the time length between two measurement and control windows is the scheduling period, namely the scheduling period of a periodic triggering mode is the time length between two measurement and control windows of a satellite system, and the basic principle diagram of sliding scheduling is shown in fig. 2.
Illustratively, after the current planned task list Plan is annotated at time T0, until the next measurement and control opportunity T1 comes, the newly arrived tasks will be accumulated because of the inability to annotate and added to the planning scheme at the next instruction annotate. Specifically, the system operator takes the task planning Plan with the time T0 as a Plan, slides the incomplete task in the Plan and the newly arrived task into the next Plan at the time Tt1 T, and reprograms the task according to the use state of the resource in the previous Plan to obtain a new planning Plan1, wherein the Plan1 is to be annotated at the time T1, T is a time threshold parameter of the beginning time of the sliding Plan, which is called a sliding window, after the new planning Plan1 is annotated, the task starts to be executed at the time Tt1 T, and the task after the Plan time in the original planning Plan is to be slid into the Plan1, wherein the value of T is specifically determined by the operator.
In order to realize the task sliding and connection during two planning periods, a single resource scheduling system monitors the on-board resources and the running state of the system through a state monitoring module, and performs corresponding state update in the planning process. In addition, to maintain the continuity of the planning, the system also maintains a task list to be observed and a task list to be returned, respectively. And during planning, the system updates a task list to be observed, a task list to be returned, an available data transmission arc section and the service condition of on-board resources according to the state monitoring result, and slides the task which is not completed in the previous planning into the current planning. The task list to be returned contains not only task information, but also use information of the tasks stored on the satellite, so that the data transmission task can be consistent with the observation task.
Dynamic tasks are selected to be dynamically scheduled or rescheduled in a sliding pushing mode, and on one hand, a planning scheme can be timely adjusted to adapt to and track the change of the system state. On the other hand, because one-time planning is needed in each sliding period, in order to reduce the time complexity of the algorithm, according to the timeliness requirement of the dynamically arrived task and the parameters such as the state and operation constraint of the observation resource at the current moment, corresponding heuristic rules are adopted in each sliding period, and the quick response to the high-dynamic observation requirement is realized by carrying out sliding type local revision or rescheduling on the original observation plan, and the relative stability of the original observation plan is maintained.
