High-pressure oxygen system

The utility model relates to the field of airplane oxygen systems, and discloses a high-pressure oxygen system which comprises an oxygen bottle, a temperature sensor, a pressure sensor, a data processing unit and a display unit. High-pressure oxygen is stored in the oxygen bottle, and a pressure reducer is arranged at a bottle opening and connected with a pipeline for outputting the oxygen. The temperature sensor is arranged on the outer side of the pressure reducer, and the pressure sensor is connected with the pressure reducer through a pipeline. And the data processing unit is electrically connected with the temperature sensor and the pressure sensor, and is used for filtering the pressure and temperature of the oxygen and calculating the oxygen percentage of the oxygen bottle according to the filtered pressure value and temperature value. The display unit is electrically connected with the data processing unit and used for displaying the oxygen content percentage of the oxygen bottle. According to the hig
