Abstract

Disclosed are a method, a device, and a storage medium for measuring the nitrogen content. The method includes determining related variables associated with the nitrogen content; establishing an initial model, wherein the initial model takes the related variables as independent variables and the nitrogen content as dependent variables according to a historical operation data, and calculating parameters in the initial model; according to parameters in the initial model, obtaining parameters in a soft-sensing model by fitting; according to detected values of the related variables and the soft-sensing model, predicting the nitrogen content in real-time; and according to the predicted nitrogen content and an actual nitrogen content obtained by periodic sampling, obtaining a fusion detection result.
