Abstract

The invention discloses a digital respiration following oxygen supply system. The digital respiration following oxygen supply system comprises a respiration rhythm sensor, a height sensor, a microcontroller, a D / A converter and proportional valves. The input end of the microcontroller is connected with the height sensor and the respiration rhythm sensor, and the proportional valves communicate with an oxygen source and an oxygen mask through oxygen transmitting pipelines. The invention further discloses an oxygen supply method of the digital respiration following oxygen supply system. The method includes the following steps that the pulmonary respiration depth P of a human body is detected; the pulmonary respiration cycle T of the human body is detected; the pulmonary ventilation flow sigma and the needed oxygen flow (O2) are worked out through a mathematical model preset in a microprocessor according to the respiration depth P and the respiration cycle T; the microcontroller converts the obtained pulmonary ventilation flow sigma and needed oxygen flow (O2) into electric signals which are then sent to the D / A converter; and the opening degree of the proportional valves is controlled according to the intensity of the electric signals through the D / A converter. The oxygen utilization rate is increased and the comfort level is improved for an oxygen user.

Description

technical field [0001] The invention relates to the field of aviation oxygen supply, in particular to a digital breath-following oxygen supply system and an oxygen supply method thereof. Background technique [0002] As the flight altitude of the aircraft increases, the oxygen in its surrounding environment becomes thinner. In order to ensure that the pilot has a good oxygen supply, an oxygen supply system is usually installed in the aircraft cockpit. 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, and second, the oxygen in the oxygen source is not completely In the case of depletion, the oxygen in the oxygen source will be polluted, and the carbon dioxi...
