Abstract

The invention provides a circulating air supply method for a marshalling running train in a vacuum environment. The method comprises the steps that whether the pressure change rate exceeds a set safety threshold value or not is judged; when the safety threshold value is within the set safety threshold value, a normal air supply assembly is used for supplying air to the compartment; when the preset safety threshold value is exceeded, a first emergency gas supply assembly is used for supplying gas to the compartment; when the pressure change rate is gradually reduced and recovered to be within the set safety threshold value, the gas supply rate of the first emergency gas supply assembly is reduced; when the pressure change rate continues to be increased, the first emergency gas supply assembly and the second emergency gas supply assembly are used for supplying gas to a first compartment; when the pressure change rate is gradually reduced and recovered to be within the set safety threshold value, the gas supply rate of the second emergency gas supply assembly is reduced; and when the pressure change rate continues to be increased, the train is stopped emergently. By means of the technical scheme, the technical problem that in the prior art, air cannot be circularly supplied to the train in the vacuum environment is solved.

Description

technical field

[0001] The invention relates to the technical field of circulating air supply for trains formed in vacuum environment, in particular to a method for circulating air supply of trains formed in vacuum environment. Background technique

[0002] Long-term manned spacecraft mainly use the method of electrolysis of water for gas supply. The electrical energy required for the reaction is generated by solar panels on the space station and sent to the oxygen generator through the power grid of the space station, and the water is sent to the space station by a cargo spacecraft. In addition, the water vapor exhaled by the astronauts will also be recovered from the air in the cabin through the condenser, and water can also be recovered from the astronauts' urine. The hydrogen produced by the electrolysis of water can react with the carbon dioxide produced by astronauts to produce water and methane (biogas). Water can be re-engaged in electrolysis to make oxygen. The m...
