Embodiment Construction
[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0043] Step 1: Set up the task list, and automatically sort the tasks in the work list on the ground according to time and priority. First of all, it is sorted by priority. The key orbital maneuver task has the highest priority and is a first-level task; the non-critical orbital maneuver task has the second highest priority and is a second-level task. The attitude maneuver task has the lowest priority and is a third-level task. Tasks are executed first. In the same priority, they are sorted by time, and the tasks with the earlier time are executed first. After the task list is sorted, the onboard computer does not adjust the task sequence independently, except for the correction on the ground, and executes it directly in order. During the execution of a certain task in the task operation table, other tasks in the task operation tabl...

An autonomous planning and executing method suitable for Mars exploration flight control tasks comprises the following steps: firstly, a task operation table is set, tasks in the operation table injected on the ground are autonomously sorted according to time and priorities, and an on-board computer executes the tasks in sequence according to the sorted operation table; then three emergency tasks,namely an energy protection task 1, a posture protection task 2 and a communication protection task 3 from high to low according to priorities are set; and after the on-board computer system autonomously interprets that the emergency task condition is met, the task time, the task type and the specific task content of the emergency task are autonomously generated and written into an emergency taskqueue; and when the emergency task needs to be executed, only the second-level task and the third-level task in the task operation table can be interrupted, and the task operation table is cleared according to preset logic.
Description
technical field [0001] The invention relates to an autonomous planning and execution method suitable for Mars exploration flight control tasks, which belongs to the application technology of a spaceborne computer system for Mars exploration. Background technique [0002] my country will launch a Mars probe in 2020. As the probe flies to Mars, the distance between the instrument and the ground increases, and the measurement and control link cannot guarantee the uninterrupted whole process. The interruption time of the test communication link will be as long as 30 days, so the Mars rover is required to have a strong ability to perform tasks autonomously. At the same time, the types of tasks in the process of Mars exploration are complex and diverse. Some tasks (such as brake capture, etc.) have only one chance and cannot be missed. Therefore, the Mars rover is required to have a strong ability to manage tasks independently. Independently adjust the execution order of tasks acc...
