Xi’an News Network reported on December 25, the Shenzhou 13 astronaut crew carried out the second out of the capsule. At 18:44, astronaut Ye Guangfu opened the cabin door and took the lead out of the cabin. At 18:51, Ye Guangfu successfully exited the cabin. In this mission, the 771 supporting products of the Ninth Academy of Aerospace Science and Technology Group were operating normally and the quality was reliable, which provided a guarantee for the complete success of the mission.
The extravehicular spacesuit is the armor for astronauts to move outside the cabin. This time the astronauts are out of the cabin, the integrated electrical console of the extravehicular service cabin developed by 771 is installed in the node module of the space station, which mainly provides data communication and power supply for the spacesuit system. Power distribution, voice communication and other functions. During the time when the astronauts exit the cabin and pass the gate, the onboard electrical integrated console of the extravehicular service provides power supply and distribution for the extravehicular space suit using the umbilical working mode, and starts data and voice wired communication services. During extravehicular operations, the astronaut’s physiological information and environmental parameters such as the pressure in the extravehicular spacesuit are transmitted to the space station cabin through the console to monitor the physical condition of the astronauts and the environmental conditions in the extravehicular spacesuit in real time to ensure exit The work went on smoothly.
The environmental control cabin exit controller developed by 771 is installed in the node cabin of the space station. It belongs to the core cabin environment control and life support sub-system, and is mainly responsible for the environmental monitoring and control of the node cabin. Before the astronauts leave the cabin, the environmental control exit controller provides power supply and distribution to the node cabin valves, electromagnetic pumps, sensors, etc. At the same time, by operating the exit controller, it sequentially performs oxygen concentration pre-control, exit preparation, and gas reuse. , Pressure relief and other preparation phase procedures for exiting the cabin. In the process of exiting the cabin, real-time monitoring and control of the environment of the node cabin, display the cabin pressure, time and other key parameters during the cabin. After exiting the cabin and returning, the node cabin is re-pressure controlled to restore the pressure in the cabin to the normal atmospheric environment.
In the life in the astronaut cabin, 771 has equipped the astronauts with medical monitoring equipment. In the Tianhe core module, the medical monitoring equipment in the crew sub-system directly serves the astronauts, and is used for daily supervision and protection of various physical indicators of the astronauts to ensure that the astronauts live healthy lives in space. The wireless physiological signal detection device routinely monitors the astronaut’s ECG, respiration, and body temperature. The sleep monitor is responsible for collecting the physiological signal data of the astronauts while they are sleeping. The non-invasive hemodynamic monitor is used for non-invasive monitoring of the astronaut’s ECG and blood oxygen pulse signals. The 12-lead Holter Monitoring Recorder integrates the functions of four types of products: conventional ECG, exercise ECG monitor, Holter monitor, and rescue ECG monitor, which can be carried by astronauts for real-time monitoring for a long time. The operating force measurement equipment measures the astronaut’s various forces from fingers to feet in an all-round way, and detects changes in the operating force of various parts of the astronaut’s body under long-term weightlessness.
In addition, in order to improve the quality of life of astronauts, the 771 Institute also provided space station microwave heating controllers, hot air heating devices, drinking water supply controllers and drinking water dispensers. With these equipment, astronauts can safely heat non-metal packaging food and drinking water to a temperature suitable for consumption, satisfying the Chinese stomach who eats hot meals and hot water, and can also make small snacks such as yogurt.
