Description

Technical Field

[0001] The present invention relates to the technical field of automatic oxygen monitoring and supply, and particularly to an automatic oxygen monitoring and supply system under a pressure environment. Background Technique

[0002] Oxygen (O2) is an important component of the Earth's atmosphere, accounting for approximately 21% of the air volume. As a colorless, odorless, and tasteless gas, oxygen is crucial for life on Earth, participating in the respiration and energy production of the vast majority of organisms. Chemically, oxygen is the eighth element in the periodic table, with relatively active chemical properties and capable of forming compounds with various elements. Oxygen is gaseous under standard conditions but can be liquefied at low temperatures or high pressures. Liquid oxygen (LOX) is pale blue, with a boiling point of approximately -183°C and is an important component of rocket fuel. The freezing point of oxygen is approximately -218°C, and solid oxygen is a blue crystal.

[0003] Oxygen is a strong oxidizing agent that can accept electrons in reactions, and this property makes it play a key role in many chemical reactions, including combustion reactions, corrosion processes, and cellular respiration. The reaction of oxygen with other substances usually releases a large amount of energy, which is the basis for organisms to produce ATP (the energy currency of cells). Biologically, oxygen is a key consumable in the process of cellular respiration. It is inhaled by organisms through respiration and used to oxidize organic matter, releasing energy, carbon dioxide, and water. This process is the basis for the survival of multicellular organisms, enabling them to maintain complex life activities.

[0004] Currently, the detection devices for the oxygen content in the environment commonly used on submarines can only monitor the oxygen content. When the oxygen content in the monitored environment is lower than the standard range, an alarm is issued. However, it is unable to automatically supply oxygen to the detected environment. Moreover, due to the special working environment of submarines with relatively high pressure, the detector is often affected by the external environment. Therefore, there is an urgent need for an improved technology to solve this problem existing in the prior art. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic oxygen monitoring and supply system under a pressure environment that can monitor the oxygen in the environment in real time, compare the monitored oxygen values in the environment, realize the real-time monitoring of the oxygen content in the environment, and replenish the oxygen in the environment in real time, ensuring that the oxygen content in the crew's working environment is always within the standard range, so as to solve the problems raised in the above background technique.
