Embodiment 1

[0054] This embodiment provides a drill-surface heterogeneous sampling system for extraterrestrial celestial bodies, which is applied to the design of a sampling system for contact soil sample collection in unmanned exploration missions of extraterrestrial celestial bodies, and can realize multi-point surface layers of extraterrestrial celestial bodies. And deep drilling collection, thereby improving the reliability of sampling.

[0055] Such as figure 1 As shown, the drill meter heterogeneous sampling system includes: drilling sampling module, shovel digging sampling module, sample packaging module, control module and environmental perception and visual monitoring module, such as Figure 14 As shown, these modules are all installed on the extraterrestrial object sampling spacecraft, the shovel sampling module is installed on the opposite side of the drilling sampling module, the sample packaging module is installed between the shovel sampling module and the drilling sampling ...

Embodiment 2

[0076] On the basis of embodiment 1, the sampling method of this drilling table heterogeneous sampling system comprises the following steps:

[0077] S1: The extraterrestrial object sampling spacecraft lands or attaches to the surface of the extraterrestrial object;

[0078] S2: Perceive the drilling sampling area by the drilling sampling environment sensing component 12 in the environmental perception and visual monitoring module, and judge the state of the drilling sampling point; Binocular stereo imaging modeling and selection of appropriate sampling points;

[0079] S3: Set the working mode of the system to the drilling sampling mode, implement drilling sampling, continue to judge the sampling status during the drilling sampling period and implement operational control on the drilling sampling, and decide whether to stop or continue the sampling according to the preset conditions during the drilling sampling period, and execute the subsequent step S4 when it needs to stop,...

Abstract

The invention discloses a surface drilling heterogeneous sampling system and method for extraterrestrial celestial bodies, and the system comprises a drilling sampling module, a shoveling sampling module, a sample packaging module and an environment perception and visual monitoring module which are disposed on an extraterrestrial celestial body sampling spacecraft, and the shoveling sampling module and the drilling sampling module are disposed at opposite sides. The sample packaging module is arranged between the shoveling sampling module and the drilling sampling module, and the position of the environment sensing and visual monitoring module is determined by the shoveling sampling module, the drilling sampling module and the sample packaging module; the method comprises the steps that the drilling sampling module is used for obtaining subsurface soil within a set depth below the surface layer of an extraterrestrial celestial body, the shoveling sampling module is used for obtaining a soil sample of the surface layer of the extraterrestrial celestial body, and the samples collected by the drilling sampling module and the shoveling sampling module are transferred into the sample packaging module; and the environment sensing and visual monitoring module is used for acquiring a sampling area topographic structure of drilling sampling and shoveling sampling and performing visual monitoring on the drilling sampling, shoveling sampling, sample packaging and sample transferring processes.

Description

technical field [0001] The invention relates to the technical field of space detection, in particular to a heterogeneous sampling system and method for extraterrestrial celestial bodies. Background technique [0002] The Chang'e-5 probe needs to realize my country's first lunar sampling return. The complex lunar surface terrain and unknown lunar soil state will bring great challenges to lunar soil collection. In the unstructured lunar surface environment under various constraints, it is necessary to ensure that samples are collected, and a reliable and efficient sampling system must be designed. [0003] At present, only the drilling method of the Soviet Union has implemented unmanned sampling and return, but the collection of samples cannot meet the needs of diversity. The United States collected samples and returned to Earth through astronauts, bringing back a large number of rock samples, but the sampling method cannot be applied to unmanned sampling return missions.
