Embodiment 1

[0087] Taking my country's first lunar surface automatic sampling return mission Chang'e-5 as an example, the implementation steps of the present invention are as follows:

[0088] 1) Instruction optimization

[0089] During the lunar surface sampling process of the Chang'e-5 probe, surface sampling and stakeout will be repeated many times until the predetermined sampling volume is completed, and the instruction optimization for this process is the most important. In the pre-optimization plan, it takes 81 minutes for a single table sampling and stakeout, and 66 ground uplink injections are performed. Since there is a certain uncertainty in the time of sampling and setting out each time, and the digital tube cannot detect whether the current state meets the conditions for sampling and setting out, the delay instruction or program control instruction cannot realize the optimization of the program. Or multi-frame / multi-packet / multi-block combined instruction mode for optimized d...

Abstract

The invention discloses a lunar surface sampling trinity flight control cooperative workflow optimization method, which comprises the following steps: compiling fixed conventional instructions in a cooperative work program into an instruction chain, and in a task implementation process, a task support center only needs to apply to a control center for one time, so that a series of actions can be completed, and interaction between systems is greatly reduced; enabling the pre-established instruction library to quickly select corresponding instructions from the instruction library to quickly form a temporary instruction plan when a field decision problem is dealt with in a task implementation process, so that the number of instructions generated on site is greatly reduced; and adopting an instruction optimization method, so that the number of times of instruction injection during lunar surface sampling is reduced, and the sampling working efficiency is improved. By comprehensively using the optimization method, the efficiency of the lunar surface sampling trinity flight control cooperative work is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of spacecraft control, and in particular relates to a three-in-one flight control collaborative workflow optimization method for lunar surface sampling. Background technique [0002] The control of the lunar surface sampling and packaging process has the characteristics of landing attitude, lunar surface shape, lunar soil characteristics, mechanical arm characteristics, and many uncertain factors in imaging effects. In my country's first unmanned automatic sampling and return mission on the lunar surface, the lunar surface trinity was adopted. Flight control cooperative work mode. Such as figure 1 As shown, the trinity refers to the coordinated work of the control center (Beijing center), application center, and mission support center to complete the flight control of the unmanned automatic sampling probe on the lunar surface. The control center is responsible for the direct control of the detector, and tra...
