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...

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] see figure 1 , the space station environmental control and life support system controller includes two fully redundant power supply units and two fully redundant environmental control and life support system units, and the two fully redundant environmental control and life support system units pass through the collector The open gate level signal circuit performs state interaction, and performs data interaction through the RS422 bus.

[0023] see figure 2 , the power supply unit of the present invention mainly provides power for the environmental monitoring and life support system unit, and can convert the voltage on the primary bus into a secondary DC voltage to supply the environment control and life support system unit.

[0024] see image 3 , the environmental control and life support system unit in the system controller of the present inventio...
