Full-intelligent online blow-in system for blast furnace oxygen lance

The invention relates to the field of intelligent control, and particularly discloses a blast furnace oxygen lance full-intelligent online blow-in system which is characterized in that the lance body temperature and the in-furnace temperature of a blast furnace oxygen lance acquired by a temperature sensor in real time are acquired; carrying out time sequence characteristic analysis on the gun body temperature and the in-furnace temperature by utilizing a data processing and analysis algorithm based on a deep learning neural network; according to the time sequence interaction response between the gun body temperature and the furnace temperature, an intelligent control instruction that the oxygen flow value at the current time point needs to be increased, decreased or kept is intelligently obtained. Through the mode, the relevance between the oxygen flow and the temperature can be more accurately grasped, and intelligent oxygen flow control is realized, so that the energy waste is effectively reduced, the depe
