Method for monitoring condition of blast furnace

Abstract

A method for monitoring a condition of a blast furnace, according to an embodiment, comprises the steps of: obtaining real-time acoustic data of an electric furnace from an acoustic sensor arranged adjacent to the electric furnace; generating a frequency image obtained by imaging the acoustic data by performing frequency time series analysis on the obtained acoustic data; extracting an acoustic pattern corresponding to a dissolution state of the electric furnace on the basis of the frequency image by using an artificial intelligence-based autoencoder; and generating an acoustic feature map from the acoustic pattern, the acoustic feature map obtained by visualizing the acoustic pattern in time series.
