[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] The first embodiment of this application is as follows: Please see Figure 1 and Figure 2 ,in, Figure 1 This is a structural block diagram of the life support system for the carbon-oxygen-water cycle of a spacecraft according to the first embodiment of the present invention. Figure 2 This is a structural block diagram of the water circulation module according to the first embodiment of the present invention. The present invention provides a life support system for a spacecraft with carbon-oxygen-water circulation: including an oxygen circulation module 101, a water circulation module 102, a monitoring module 103, and a control module 104. The water circulation module 102 includes a water supply unit 105, a wastewater treatment unit 106, a water recycling unit 107, and a water management and monitoring unit 108.

[0020] In this specific embodiment, the control module 104 is connected to the monitoring module 103, the oxygen circulation module 101 is connected to the control module 104, and the water circulation module 102 is connected to the control module 104. The oxygen circulation module 101 is used to provide oxygen and convert carbon dioxide into harmless substances. The water circulation module 102 is used to provide a water source for drinking water, bath water, coolant, and other equipment that requires water; The monitoring module 103 is used to monitor environmental data in the spacecraft; The control module 104 is used to acquire environmental data and adjust the oxygen circulation module 101 and the water circulation module 102 according to the environmental data.

[0021] The oxygen circulation module is responsible for providing astronauts with the oxygen needed for breathing. It extracts oxygen through water electrolysis or the decomposition of other compounds for astronauts to breathe. Simultaneously, a carbon dioxide removal system removes exhaled carbon dioxide from the astronauts, converting it into harmless substances. The water circulation module 102 is responsible for providing drinking water, bath water, coolant, and water for other equipment requiring water. A wastewater regeneration system converts the astronauts' wastewater into reusable water, achieving water resource recycling. The monitoring module 103 monitors environmental conditions such as temperature, humidity, and air pressure within the spacecraft and uploads the data to the control module 104. The control module 104 adjusts the oxygen circulation module 101 and the water circulation module 102 based on the environmental data to control the air quality inside the cabin, ensuring the health and safety of the astronauts.

[0022] The water supply unit 105 is connected to the wastewater treatment unit 106. The water supply unit 105 is used to provide water for drinking water, bath water, coolant, and other equipment that requires water; The wastewater treatment unit 106 is used to collect wastewater from the spacecraft and perform preliminary treatment.

[0023] The water supply unit 105 provides water for drinking water, bath water, coolant, and other equipment that requires water. In the spacecraft, water must be recycled, so wastewater can be reused after treatment. The wastewater treatment unit 106 performs preliminary treatment steps such as filtration, disinfection, and deodorization on the wastewater, which can then be reused for drinking, washing, and other purposes.

[0024] Secondly, the water recycling unit 107 is connected to the wastewater treatment unit 106 and the water supply unit 105 respectively; The water recycling unit 107 converts the pre-treated water into reclaimed water that meets quality standards and supplies it to the water supply unit 105.

[0025] The water recycling unit 107 uses efficient filtration and regeneration technology to convert wastewater into reclaimed water that meets quality standards. This process requires precise control and monitoring to ensure the safety and reliability of water recycling. The reclaimed water is then delivered to the water supply unit 105 for use.

[0026] Meanwhile, the water management monitoring unit 108 is connected to the water supply unit 105, the wastewater treatment unit 106, the water recycling unit 107 and the control module 104 respectively; The water management monitoring unit 108 is used to manage and monitor water quality, water quantity and temperature.

[0027] The water management and monitoring unit 108 manages and monitors parameters such as water quality, water quantity, and temperature in the water circulation module 102 to ensure the safety and comfort of astronauts. It includes various sensors, control valves, and displays.

[0028] Using a spacecraft carbon-oxygen-water cycle life support system according to this embodiment, the wastewater treatment unit 106 collects wastewater and performs preliminary treatment, then converts it into reclaimed water that meets quality standards at the water recycling unit 107, and then recycles it to the water supply unit 105. During the water recycling process, the water management and monitoring unit 108 monitors the water quality, water temperature and temperature in real time and makes timely adjustments. At the same time, the monitoring module 103 monitors the changes in the spacecraft's internal environment in real time, and the control module 104 controls the water recycling module 102 according to the environmental changes, realizing the recycling of resources inside the spacecraft, greatly reducing dependence on external resources, improving the spacecraft's autonomy and sustainability, and ensuring a stable and suitable internal environment for the spacecraft, which can guarantee the health of astronauts, reduce the occurrence of diseases, and improve the survival rate of astronauts.

[0029] The second embodiment of this application is as follows: Based on the first embodiment, please refer to Figure 3 ,in, Figure 3 This is a structural block diagram of an oxygen circulation module according to a second embodiment of the present invention. The oxygen circulation module 101 in this embodiment includes an oxygen generation unit 201, a carbon dioxide removal unit 202, and a gas control and monitoring unit 203.

[0030] In this specific embodiment, the oxygen generation unit 201 is connected to the carbon dioxide removal unit 202; The oxygen generating unit 201 is used to generate oxygen; The carbon dioxide removal unit 202 is used to convert carbon dioxide into harmless substances and oxygen, and to deliver the oxygen to the oxygen generation unit 201.

[0031] The oxygen generation unit 201 produces oxygen by electrolyzing water or decomposing other compounds to meet the breathing needs of astronauts. Electrolysis of water is the most common method, which uses an electric current to decompose water into oxygen and hydrogen. The oxygen is used for oxygen supply, while the hydrogen can be used as fuel. The carbon dioxide removal unit 202 converts the carbon dioxide exhaled by astronauts into harmless substances, such as sodium carbonate or sodium bicarbonate, through a chemical reaction. These substances can be safely released into space, collected for reuse, or converted into oxygen and returned to the astronauts.

[0032] The gas control and monitoring unit 203 is connected to the oxygen generation unit 201, the carbon dioxide removal unit 202 and the control module 104 respectively. The gas control and monitoring unit 203 is used to control and monitor the gas composition and pressure.

[0033] The gas control and monitoring unit 203 controls and monitors the gas composition and pressure in the oxygen circulation module 101 to ensure the safety and comfort of astronauts, and includes various sensors, control valves and displays.

[0034] The life support system for a spacecraft using a carbon-oxygen-water cycle according to this embodiment provides astronauts with sufficient oxygen and a suitable living environment through an efficient oxygen generation and carbon dioxide removal system in the oxygen circulation module 101. Simultaneously, the monitoring module 103 monitors changes in the spacecraft's internal environment, and then the control module 104 controls the oxygen circulation module 101 to adjust the environment based on these changes. Through carbon-oxygen-water circulation, the system achieves the recycling of resources within the spacecraft, significantly reducing dependence on external resources and improving the spacecraft's autonomy and sustainability. The stable and suitable internal environment ensures the astronauts' health, reduces the incidence of disease, and improves their survival rate. It provides suitable temperature, humidity, and air pressure, filters and controls air quality to ensure astronaut comfort, and simplifies spacecraft system design through centralized management and control. This reduces the number and complexity of equipment, lowers maintenance costs, and provides necessary safety measures, such as preventing hypoxia and carbon dioxide accumulation, thus improving spacecraft safety. Ultimately, it provides a safe, comfortable, and reliable living environment for astronauts, improving their survival rate and work efficiency, while also reducing maintenance costs and enhancing spacecraft safety.
