Abstract

In this paper, a method of measuring NH₃ gas concentration based on fuzzy neural network is proposed. The 1560nmlaser is used as the pump laser source, and an all-fiber thulium-doped fiber ring laser system is built. Wave length scanning technology is used to scan the spectrum of different concentrations of NH₃ gas in the range of 1957-1960nm, and the spectral data is collected and preliminary-processed. Then the fuzzy neural network model is used to measure the concentration of NH3 gas. The method proposed in this paper can effectively avoid the influence of temperature and pressure changes and measurement errors of experimental equipment on ammonia concentration detection. The experimental results show that the system has high accuracy and strong robustness.
