Embodiment Construction
[0026] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.
[0027] figure 1 Shown is a flow chart of the gas concentration measuring method of the embodiment of the present invention.
[0028] Step S101, collecting background gas, and measuring the spectral lines of the background gas.
[0029] Since the spectral lines of the background gas are used as reference values for the subsequent calculation of the spectral lines of the gas to be measured, the quality of the background gas measurement will directly affect the measurement accuracy of the subsequent gas to be measured. In the embodiment of the present invention, the background gas usually comes from a space with relatively good greening and little gas change, and usually the gas collected from a point near the green belt outside is used as...
