Abstract

The integrating sphere gas chamber is selected as the core of the detection system, and a new algorithm is used to calculate hydrogen gas concentration. LED light source is selected as the detection system light source, and LED source wavelength is processed by fiber grating and piezoelectric ceramic, then the light source corresponding to the hydrogen gas wavelength absorption peak is obtained. The light source passes through two integrating sphere chambers of the same state at the same time, because the light intensity of the light source is absorbed by hydrogen gas and the inner wall of the integrating sphere gas chamber, calculates the source signal by using an algorithm, and the real-time concentration of hydrogen gas obtained. Experiments show that the theoretical algorithm agrees well with the experimental results.
