Description

technical field [0001] The invention relates to the field of aviation oxygen supply, in particular to a digital breathing following oxygen supply system and an oxygen supply method thereof. Background technique [0002] As the flight altitude increases, the oxygen in the surrounding environment of the aircraft becomes thinner. In order to ensure that the pilot has a good oxygen supply, an oxygen supply system is usually installed in the cockpit of the aircraft. At present, the oxygen supply methods of domestic oxygen regulators mainly adopt the following two methods: continuous oxygen supply and intermittent oxygen supply. Continuous oxygen supply is continuous and uninterrupted supply of oxygen to the user. This oxygen supply method cannot separate the oxygen in the oxygen source. First, it will cause a lot of waste of oxygen. Second, the oxygen in the oxygen source is incomplete. In the case of exhaustion, the oxygen in the oxygen source will be polluted, and the carbon d...
