Hydrogen is an important industrial raw material and also a clean energy with wide development prospects.However,hy-drogen is a flammable and explosive gas,it is essential to detect its concentration in the process of hydrogen production,storage and application.In this paper,for hydrogen refuelling stations,hydrogen-carrying pipelines and other scenarios with large-range and long-distance requirements for hydrogen detection,a Raman spectroscopy-based hydrogen leakage telemetry experimental device is proposed to measure the Raman scattering signals of hydrogen and nitrogen in the air at the same time,so that hydrogen leakage with a concentration of 1%can be detected at a minimum distance of 1m.
