Blast furnace ironmaking injection intelligent control system

The invention relates to the technical field of blast furnace ironmaking injection control, and particularly discloses a blast furnace ironmaking injection intelligent control system which comprises a blast furnace temperature monitoring module, a blast furnace heat utilization analysis module, a blast furnace oxygen enrichment collection analysis module, a blast furnace nozzle information collection analysis module, a cloud database and a blast furnace ironmaking control module. According to the method, the heat utilization sufficient index of the target blast furnace is analyzed, when the heat utilization sufficient index of the target blast furnace is smaller than the set value, the oxygen supply conformance coefficient and the injection conformance coefficient of the target blast furnace are analyzed, and injection abnormity reason analysis and injection abnormity control are carried out, so that the heat utilization analysis accuracy of the target blast furnace is improved; meanwhile, the persuasion and
