Abstract

The invention relates to a gas detection method and device based on a sound velocity frequency dispersion spectrum inflection point, electronic equipment and a computer readable storage medium. The method comprises the steps: obtaining the frequency and sound velocity value of to-be-detected gas, taking the frequency of the to-be-detected gas as an independent variable, and taking the sound velocity value of the to-be-detected gas as a dependent variable to construct a sound velocity frequency dispersion spectrum curve function; calculating to obtain the relaxation frequency and the sound velocity value of an inflection point on the sound velocity frequency dispersion spectrum curve according to the coefficient value of the sound velocity frequency dispersion spectrum curve function; and determining the gas components of the to-be-detected gas according to different relaxation frequencies and sound velocity values of the corresponding inflection points under different gases and different concentrations. According to the gas detection method based on the sound velocity frequency dispersion spectrum inflection point, the accuracy of gas detection is improved, and the detection range of gas detection is enlarged.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a gas detection method, device, electronic equipment and computer-readable storage medium based on the inflection point of the sound velocity dispersion spectrum. Background technique [0002] Gas plays an important role in people's production and life. Various gases are often used in industry, such as nitrogen and hydrogen in the process of chip manufacturing, but some gases are dangerous, and some gases are mixed with air to reach a certain level. The concentration may cause accidents such as fire and explosion, so it is of great significance to detect the gas composition. [0003] In the prior art, the gas sensor is used to detect the gas, the equipment cost is high, and the gas is detected by the peak point of the acoustic relaxation absorption spectrum, the accuracy is low and has limitations, and the gas components of the mixed gas with the same molecular weight canno...
