A hierarchical convolutional neural network (CNN) model for mixed gas concentration inversion is proposed. In our experiment, mixtures of SO2, NO2, and NH3were analyzed. SO2and NO2were the detected gases, while NH3was the interfering gas. For the simulation samples, the average absolute errors were 0.5 and 0.9 ppm for SO2and NO2, respectively. For the experimental samples, the model performed well when the absorption intensities of components differed by no more than one order of magnitude. Compared with the single-module CNN model without a hierarchical structure, the results demonstrate that the hierarchical structure reduces cross-interference and improves the prediction accuracy to a great extent. We believe that our model will have a promising application in the field of gas detection.
