Abstract

The patent of the invention belongs to the technical field of aerospace life support, and discloses a miniature terrestrial ecosystem that can operate in a microgravity environment, and is mainly used for micro-ecological system operation experiments in a weightless environment. The present invention mainly includes a plant area 1, an animal area 2, a solid waste area 3, a water tank area 4, and an electric control area 5. Plants can be planted in plant area 1 to produce oxygen for biological utilization in animal area 2 and solid waste area 3; animals can be raised in animal area 2, and microorganisms can be inoculated to treat solid waste in solid waste area 3, both of which can produce carbon dioxide for plants Plant utilization in zone 1; water tank zone 4 can provide water for plants and realize system water circulation; electric control zone 5 can monitor and control various physical and chemical indicators and parameters of each zone in the system, and at the same time provide light for plants to ensure normal operation of the device run. The invention has simple structure and high degree of automation, and can be used to study the influence of special conditions of space environment on the whole terrestrial ecological system and each biological chain link.

Description

technical field [0001] The present invention proposes a miniature terrestrial ecosystem experiment device that can operate in a microgravity environment, and can carry experiments on orbiting aircraft such as spacecraft and space stations. At the same time, it can also realize the independent operation of each biological module to study the parameters of the system. The invention has compact structure, complete partitions, high space utilization rate and high degree of automation, and can study the influence of special conditions of space environment (microgravity, weak magnetic field, long-term low-dose radiation) on the whole terrestrial ecosystem and each biological chain in real time. Background technique [0002] With the rapid development of human spaceflight, the scope of human exploration of extraterrestrial planets continues to expand. The establishment of a lunar base and manned landing on Mars have become the main research tasks at present. In order to realize th...
