[0004] The traditional test method verifies the correctness of its design by annotating instructions and checking the response of the spacecraft. When it is applied to the test of intelligent mission planning, after the mission information is annotated, it can only passively wait for the execution result of the spacecraft, and cannot carry out the process. Monitoring and intervention, once the instruction sequence generated by the intelligent algorithm on the on-board computer makes an error, the test will fail at least, and the equipment and products on the spacecraft will be damaged at worst. Therefore, the traditional test method cannot meet the test and verification of the intelligent autonomous mission planning function of the spacecraft. demand, and there are major security risks

The invention discloses a spacecraft intelligent task planning test method and system. According to the method, a directed graph model the same as that on a spacecraft and a task pool are loaded on the ground, a command sequence required by executing tasks is simulated and generated according to a tested intelligent task planning algorithm, collision detection and correctness judgment are conducted, and top pouring is conducted on the spacecraft after the collision detection and correctness judgment are successful; the spacecraft downloads the command sequence required by executing the tasks are generated by the spacecraft to the ground, correctness judgment is conducted again, if certain tasks are failed, the error tasks are deleted through a top pouring deleting task block on the ground. By means of the spacecraft intelligent task planning test method and system, the task planning result can be initiatively obtained and judged so as to guarantee test safety, and ground monitoring of and interference with the spacecraft test process can be achieved.
Description
technical field [0001] The invention belongs to the technical field of spacecraft testing, and in particular relates to a testing method and a testing system for spacecraft intelligent task planning. Background technique [0002] Compared with the traditional static operation control mode based on command templates, the dynamic operation control mode based on intelligent mission planning can effectively release the autonomous task optimization capability of the on-board computer on the spacecraft and significantly improve the use efficiency of the spacecraft. Research hotspots in the process of spacecraft development. [0003] At present, the basic methods of intelligent task planning are, such as figure 1 As shown, there is a task pool and a directed graph model on the spacecraft. There are tasks arranged over time in the task pool, such as taking pictures, deploying the robotic arm, etc., and the reachable paths between nodes and nodes in the directed graph model ; When ...
