As a bionic sensing device, the electronic nose system can enable the identification of complex gas components and quantitative concentration analysis by integrating multi-channel sensor arrays and artificial intelligence algorithms. In this study, a sensor array was constructed with 8 commercial gas sensors, and the design of the electronic nose system was finalized. A data processing method based on recurrence plots fused with sensor array data was proposed for sensor signal reconstruction, and a gas recognition model was built by combining deep neural networks. A simple two-dimensional convolutional neural network (2D-CNN) model achieved a recognition accuracy of 98.37% for 6 types of gases. Four concentration prediction algorithms were compared, among which the deep neural network algorithm performed optimally, achieving a root mean square error (RMSE) of 1.0695. Furthermore, the gas recognition model was optimized by incorporating the VGG-19 model, reaching a gas recognition accuracy of 98.91% and reducing the RMSE of concentration prediction to 0.5121.
