Wide-area oxygen concentration measurement method and realization device intelligent wide-area oxygen measurement instrument thereof

Abstract

The invention discloses a wide-area oxygen concentration measurement method and a realization device intelligent wide-area oxygen measurement instrument of the wide-area oxygen concentration measurement method, and belongs to the technical field of the oxygen concentration measurement method and the oxygen measurement instrument. The invention aims to provide the oxygen measurement method and the realization device of the oxygen measurement method capable of automatically adapting to the altitude. The wide-area oxygen concentration measurement method adopts the following technical scheme: 1. collecting a current oxygen concentration value a1 and a current atmospheric pressure value p; 2. calculating a real-time altitude value H by the atmospheric pressure formula H=(RT / gm)*1n(P0 / p), and solving a real-time altitude value H; 3. according to an altitude correction coefficient formula K0=5.3788*10<-9>.H<2>-1.1975*10<-4>.H+1, solving the altitude correction coefficient value K0; 4. collecting the current oxygen concentration value a2 to obtain the sampling average value N of the oxygen concentration; and 5. obtaining the corrected oxygen concentration value N0 according to that the formula oxygen concentration value N0 is equal to the sampling average value N / K0 of the oxygen concentration. The wide-area oxygen concentration measurement method and the realization device intelligent wide-area oxygen measurement instrument of the wide-area oxygen concentration measurement method can be widely applied to the altitude 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.

[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.
