Mars rover exploration task efficient autonomous operation method

Abstract

The invention discloses a Mars rover exploration task efficient autonomous operation method, which fills the blank of implementing an exploration task control method under a low uplink code rate and high delay measurement and control link in the deep space exploration field. According to the technical scheme, the method comprises the steps that firstly, a parameterized instruction template is formed through an instruction sequence corresponding to a typical detection task of a Mars rover; and then task scheduling models corresponding to the detection tasks are formed and stored in a Mars rover data management computer. Ground user personnel determines key task parameters required for completing the instruction sequence according to actual task requirements, and sends the key task parameters to the Mars rover data management computer according to an agreed task data interface form. After receiving the key task parameters, the Mars rover data management computer starts to plan a mechanism maneuvering path if judging that preconditions are met, selects a corresponding scheduling model to call a related parameterized instruction template, fills in a mechanism moving target, task duration and related load parameters, and autonomously generates a complete task instruction sequence.

Description

technical field [0001] The invention relates to the technical field of spacecraft, in particular to a method for highly efficient and autonomous operation of a Mars rover exploration mission. Background technique [0002] On July 23, 2020, China launched the Tianwen-1 Mars rover, which integrates "circling, landing, and patrolling". The rover carried a Mars rover to inspect the surface of Mars. On May 15, 2021, the landing patrol successfully completed the EDL process control and post-landing program control, and established a living state autonomously after landing. On May 22, 2021, the Mars rover successfully left the landing platform and began scientific exploration of the fire surface. [0003] The rover controls its exploration mission on the surface of Mars by injecting mission instruction data from the ground system. Since Mars is far away from the earth, the rover’s ability to directly communicate with the ground is weak, and the delay in command injection can reac...

Problems solved by technology

[0004] Compared with the lunar rovers in the field of deep space exploration, because the measurement and control is visible to the ground all day long, and the distance is short, the uplink delay is only 1s, the code rate can reach 2000bps, and the ground can be remotely controlled in real time, so there is no such thing as a Mars rover that can run efficiently and autonomously.
