AI Technical Summary

Technical Problem

Existing technologies struggle to effectively identify the dynamic response of multi-component mixed gases. Traditional modeling methods neglect the transient characteristics of gas diffusion and chemical reactions, resulting in insufficient model accuracy, cumbersome and heavy testing schemes, large testing volumes, and difficulty in adapting to the performance differences of different sensors.

Method used

A small-sample adaptive dynamic response modeling method for mixed gas sensors is adopted. By constructing a gas sensor array, simulating gas pulse signals and response signals, short time segments are generated. Using GRU network and transfer learning, a concise dynamic response model of the gas sensor is constructed to achieve data augmentation and feature extraction.

Benefits of technology

With limited data and resources, it can quickly adapt to environmental changes, improve the accuracy and efficiency of mixed gas component identification, reduce testing pressure, simplify model structure, and enhance the dynamic response accuracy of gas sensors.
