An oxygen supply control system based on imu

Abstract

A IMU -based oxygen supply control system, including the control module, is connected with the motion status recognition module, the breathing signal detection module, the physiological parameter collection module, and the solenoid valve connection in the oxygen supply module.The amount of volume, breathing signal data and physiological parameter information, determine the oxygen supply, the starting point T and the oxygen supply time T at the time of the user's real -time oxygen consumption and breathing signal data.The control module controls the opening of the solenoid valve for oxygen supply, and monitors the wearer's physical health in real time according to the information obtained by the physiological parameter collection module.The present invention strictly controls the oxygen supply and performs real -time detection based on the oxygen demand of the wearer to improve the utilization rate of oxygen use and oxygen.Ensure the personal safety of the user.

Description

technical field [0001] The invention relates to the technical field of automatic oxygen flow control, in particular to an IMU-based oxygen supply control system. Background technique [0002] The atmosphere in high-altitude areas is characterized by low pressure and low oxygen. With the increase of altitude, the air becomes thinner. Staff in high-altitude areas will experience symptoms of altitude sickness such as headache, nausea and vomiting, and unresponsiveness. Therefore, additional oxygen is required. It is inhaled to maintain the normal functioning of the body and is of great significance for performing important work or military work at high altitudes. Many workers in high-altitude areas carry oxygen cylinders or oxygen bags for oxygen supply, but the traditional oxygen supply mode causes unnecessary waste of oxygen and cannot be used for a long time. Therefore, automatic adjustment of oxygen supply becomes a better choice. [0003] However, the pulsed oxygen supply...

Problems solved by technology

Many workers in high-altitude areas will carry oxygen cylinders or oxygen bags with them for oxygen supply, but the traditional oxygen supply mode causes unnecessary waste of oxygen and cannot be used for a long time. Therefore, automatic adjustment of oxygen supply becomes a better choice

[0003] However, the pulse oxygen supply system currently on the market has the disadvantages of low response sensitivity, sometimes not supplying oxygen during inhalation, and the amount of oxygen supply cannot be changed according to the needs of the human body.

For example, the existing pulse oxygen supply system adopts the method of pulse oxygen supply at fixed time intervals, which cannot automatically match the breathing of the user; some pulse oxygen supply systems require the user to manually adjust the oxygen supply according to their own feelings. Waste of user time and poor utilization of oxygen
