Method, device and equipment for monitoring faults in ironmaking process

The invention discloses an ironmaking process fault monitoring method, device and equipment and a computer readable storage medium. The method comprises the following steps: standardizing a data set under a normal ironmaking working condition, calculating a JS divergence value between every two variables in the data set, constructing a JS divergence value matrix and setting division values, and dividing the data set into a plurality of variable blocks, extracting a feature information set of each variable block, inputting each piece of feature information and each variable block into the PCA model, obtaining a monitoring statistic control limit under a global normal working condition, determining a detection threshold value, and constructing an ironmaking process fault monitoring model. And standardizing a to-be-monitored data set, and inputting the standardized data set into the ironmaking process fault monitoring model for monitoring and judging whether a fault occurs or not. According to the method, the fe
