Embodiment 1
[0032] The present invention is described by taking the Mars rover as an example. The specific implementation steps of a method for detecting and repairing anomalies of resources in an autonomous spacecraft that has not executed a planning sequence disclosed in this embodiment are as follows:
[0033]Step 1. According to the unexecuted planning sequence P of the spacecraft, estimate the total consumption of different resources by the actions in P, determine and record the time when the first abnormality of different resources occurs.
[0034] Assume that in the initial state I, the Mars rover R is located at location w3, carrying payloads such as cameras, rock sampling and analysis tools, and soil sampling and analysis tools, with 8 units of stored electric energy and 300 units of storage space. The lander L sends back the high-resolution photo of the observation target o1, the rock analysis data at w3, and the soil analysis data at w2. The planning sequence P is shown in Tab...

The invention relates to a method for detecting and repairing anomaly of an autonomous spacecraft unexecuted planning sequence resource, and belongs to the technical field of spacecraft autonomous task planning and repairing. In the execution stage of the spacecraft task planning sequence, the present invention roughly estimates the total consumption of different resources by actions in the sequence for the given spacecraft that has not executed the planning sequence, determines and records the time when different resources first appear abnormal, and clarifies resource restoration the final moment. For different abnormal resources, before the abnormality occurs for the first time, the task planning repair method based on state regression is used to find and determine the resource repair action sequence, record all feasible repair plans, and select the plan with the smallest total resource consumption among them. Finally, in order to integrate with the original unexecuted planning sequence, add resource supply action and return action sequence after the above scheme, and adjust the start time of the action appropriately, which is the final feasible task planning sequence without resource exception.
Description
technical field [0001] The invention relates to a method for detecting and repairing resource anomalies in an unexecuted planning sequence of an autonomous spacecraft, in particular to an autonomous anomaly detecting and repairing method for replenishing consumable resources in an unexecuted planning sequence of a spacecraft during the task execution process, and belongs to spacecraft Autonomous Mission Planning Restoration Technical Field. Background technique [0002] With the continuous progress and development of artificial intelligence technology, the autonomy of spacecraft has gradually become one of the hot research directions in the aerospace field. For near-Earth satellites, the uploading of mission operation instructions is limited to the measurement and control arc of the ground station, which restricts the timely discovery and quick resolution of faults in the execution of the ground; Due to the huge time delay, relying only on the ground to provide the sequence...
