Space capsule leaving environment monitoring and control device, and control method thereof

Abstract

The invention discloses a space capsule leaving environment monitoring and control device, and a control method thereof. The monitoring and control device comprises a plurality of redundant power supply units and environment monitoring and control units, wherein the environment monitoring and control units are connected through an interaction channel and can send display information to a display operation unit to be displayed; and each environment monitoring and control unit comprises a processor module and a power supply conversion module, wherein the processor module is connected with an environment parameter collection module, an environment control output module, a bus communication module, a key parameter display driving module, a reset circuit, a clock circuit and a memory. The control method comprises the following steps that: carrying out collection processing on various environment parameters of an air brake capsule; and according to the collected various environment parameters, sending a control instruction to carry out an operation of starting and shutting down a corresponding execution mechanism and sensor, and judging whether key parameters in a capsule leaving processare normal or not through the display operation unit. By use of the device, space capsule leaving environment and real-time control problems can be solved.

Description

Technical field [0001] The invention belongs to the field of automatic control, and specifically relates to a space cabin environment monitoring and control device and a control method thereof. Background technique [0002] At present, the environmental monitoring and control in manned spacecraft in China is mainly for the cabin environment, and the monitoring results are transmitted to the instrument system through the bus for display, and the astronauts need to observe the key parameters such as time and pressure in the exit environment in real time when exiting the cabin. The monitoring results of the astronauts, and higher-precision control, the traditional in-vehicle environment monitoring and control can no longer meet the needs of the space station astronauts’ exit work. Therefore, it is necessary to develop a monitoring and control device for the astronaut’s exit environment. The monitoring of environmental parameters such as the environmental pressure, temperature, and h...

AI Technical Summary

Problems solved by technology

[0002] At present, the environmental monitoring and control in my country's manned spacecraft is mainly aimed at the cabin environment, and the monitoring results are transmitted to the instrument system for display through the bus. When leaving the cabin, the astronauts need to observe key parameters such as time and pressure in the cabin environment in real time. The monitoring results and higher-precision control are carried out. The traditional monitoring and control of the cabin environment can no longer meet the needs of astronauts working outside the cabin on the space station. Therefore, it is necessary to develop a monitoring and control device for the astronauts’ cabin environment. The monitoring of environmental parameters such as pressure, temperature, humidity and other environmental parameters of the space station, provides real-time data of environmental parameters for astronauts’ activities, ensures the safety of the environment in emergencies, and meets the requirements of high reliability and real-time performance
