Space station environment control and life-support system controller, and control method

Abstract

The invention relates to a space station environment control and life-support system controller, and a control method. The system controller comprises multiple redundantly arranged power supply unitsand multiple redundantly arranged environment control and life-support system units; the environment control and life-support system units are connected through an interaction channel; the environmentcontrol and life-support system unit comprises a processor module and a power conversion module; the processor module is connected to a sub-system management module, a data sending module, a state telemetry module, a reset circuit, a clock circuit, a data storage and a program storage; and the power conversion module respectively converts secondary direct-current voltage provided by the power supply units into working voltage required by the sub-system management module, the data sending module and the state telemetry module. The control method comprises the steps of: collecting environment monitoring data of each sub-system, and then, analyzing the collected environment monitoring data through the system controller. By means of the space station environment control and life-support system controller, and the control method in the invention, reliable living environment parameter real-time data can be provided for astronauts.

Description

technical field [0001] The invention belongs to the field of automatic control, and relates to a space station environment control and life support system controller and a control method. Background technique [0002] The environmental control and life support systems currently applied to my country's manned spacecraft are mainly to ensure that astronauts stay in orbit for a short period of time, and cannot perform on-orbit replacement and maintenance. The long-term on-orbit (15 years) of the space station requires a huge amount of data transmission, regenerative and non-regenerative subsystem management, and on-orbit maintenance. The traditional environmental control and life support systems cannot meet the requirements of space station astronauts staying in orbit. Therefore, it is necessary to develop a new cabin environment control and life support device to realize water treatment subsystem, urine treatment subsystem, CO 2 The management of the removal subsystem, the el...

[0002] The environmental control and life support system currently applied to my country's manned spacecraft is mainly to ensure that astronauts stay in orbit for a short period of time, and cannot perform on-orbit replacement and maintenance

The long-term on-orbit (15 years) of the space station requires a huge amount of data transmission, regenerative and non-regenerative subsystem management, and on-orbit maintenance. The traditional environmental control and life support systems cannot meet the requirements of space station astronauts staying in orbit. Therefore, it is necessary to develop a new cabin environment control and life support device to realize water treatment subsystem, urine treatment subsystem, CO 2 Management of the removal subsystem, electrolytic oxygen production subsystem, and trace removal subsystem, real-time monitoring and control of regenerative and non-regenerative subsystems in the space living environment, with high reliability and strong real-time characteristics
