The invention discloses a computer system based on a blast furnace-hot blast stove safe temperature control calculation model, and the system comprises a feeding recognition module which is used for obtaining the smell, shape and color data of ores after the ores enter a blast furnace; the processing information database comprises two sub-databases; wherein information entries of the ore are pre-stored in the first sub-database and are used for realizing matching of the processing time and the vault temperature of the ore; the second sub-database pre-stores process entries of the ore and is used for realizing matching of initial processing parameters of the ore; the real-time monitoring module is used for collecting real-time data in the ore processing process; and the model prediction module is used for predicting and outputting prediction parameters of the blast furnace-hot blast stove at the next moment by utilizing the blast furnace-hot blast stove safe temperature control calculation model based on the ore processing information and the real-time data, and carrying out furnace-hot blast stove regulation and control according to the parameters so as to realize temperature control in the processing process.
