Automatic control system for copper converter converting

The invention discloses an automatic control system for copper converter converting, which comprises a slag forming end point detection unit and a copper forming end point detection unit, wherein the slag forming end point detection unit is used for online collecting characteristic spectrum emission intensity signals of PbO and PbS of the melt in the copper converter in the slag forming period; the copper forming end point detection unit is used for online collecting gas concentration signals of SO2 in flue gas in a copper converter gas duct in the copper forming period; a data processing unit is used for analyzing and processing the signals collected by the slag forming end point detection unit and the copper forming end point detection unit to judge whether converting reaches the slag forming end point and the copper forming end point, and performs regulation and control to determine whether blowing out is performed. The control system can accurately judge the slag forming end point and the copper forming e
