摘　　要：氢气是一种重要的工业原料,也是具有广泛发展前景的清洁能源。然而氢气是一种易燃易爆的气体,在氢气的生产、存储和应用等环节对其浓度进行检测都是十分有必要的。针对加氢站、载氢管道等对氢气检测有大范围、远距离要求的场景,提出了一种基于拉曼光谱的氢气泄漏遥测实验装置,同时测量氢气和空气中氮气的拉曼散射信号,可以在1m的距离处最低检测到浓度为1%的氢气泄漏。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.
