Abstract

A wide-area oxygen concentration measurement method and its realization device intelligent wide-area oxygen measurement instrument, which belong to the technical field of oxygen concentration measurement method and oxygen measurement instrument; the technical problem to be solved is to provide an oxygen measurement method that can automatically adapt to altitude and Its realization device; the technical scheme adopted is: the first step, collect current oxygen concentration value a1 and current atmospheric pressure value p, the second step, pass the formula H=(RT / gM)*ln(P 0 / p), calculate the real-time altitude value H, the third step, through the altitude correction coefficient formula K 0 =5.3788x10 -9 •H 2 -1.1975x10 -4 •H+1, calculate the altitude correction coefficient value K 0 , the fourth step, collect the current oxygen concentration value a2 again, and obtain the oxygen concentration sampling average value N, the fifth step, use the formula oxygen concentration value N 0 = Oxygen concentration sampling average N / K 0 , get the corrected oxygen concentration value N 0 ; The present invention can be widely used in plateau environment.

Description

technical field [0001] The invention relates to a method for measuring oxygen concentration in a wide area and an intelligent wide-area oxygen measuring instrument for its realization device, which belongs to the technical field of methods for measuring oxygen concentration and oxygen measuring instruments. Background technique [0002] The plateau is characterized by thin air, and as the altitude rises, the partial pressure of oxygen in the air decreases continuously. Under the condition of hypoxia, the human brain, heart, and lung functions are easily damaged. Common diseases in the plateau include: acute mountain sickness, plateau Pulmonary edema, alpine cerebral edema, and chronic altitude sickness, etc. Therefore, working and living at high altitudes often requires the use of some oxygen-generating equipment, and when the human body inhales oxygen, it is necessary to keep abreast of the concentration of inhaled oxygen.

Problems solved by technology

[0002] The plateau is characterized by thin air, and as the altitude rises, the partial pressure of oxygen in the air decreases continuously. Under the condition of hypoxia, the human brain, heart, and lung functions are easily damaged. Common diseases in the plateau include: acute mountain sickness, plateau Pulmonary edema, alpine cerebral edema, and chronic altitude sickness, etc. Therefore, working and living at high altitudes often requires the use of some oxygen-generating equipment, and when the human body inhales oxygen, it is necessary to keep abreast of the concentration of inhaled oxygen. Excessively high or low oxygen concentrations will affect us The oxygen meter is mainly used to measure the purity of oxygen in the air and the purity of oxygen produced by molecular sieve oxygen equipment. However, the current conventional oxygen meter is designed for use in plain environments. When used in plateau environments, Affected by the partial pressure of oxygen in the air, the displayed data deviates greatly. At present, the oxygen measuring instruments produced at home and abroad all have this defect, which cannot meet the requirements of plateau users to accurately grasp the oxygen content.
