| Abstract: | In order to improve the hypoxic condition of the body at high altitude and low pressure environment, a portable plateau respirator based on single-chip control was developed. The respirator was composed of pump motor, intake and vent electromagnetic valveI pressure sensor and single chip microcomputer control system and supply unit, it＇ s simple and light. The system pressurized air to fit the body of the standard atmospheric pressure by the pump motor, the single chip microcomputer measured the pressure sensor＇ s signals, then to control the electromagnetic valve on and off to achieve the breathing process. Through the experiment contrast on plateau, the respirator can adjust human body heart rate and oxygen saturation very well. |
