System and method for steel-making online end-point control through furnace mouth radiation information fusion

The invention discloses a system and a method for steel-making online end-point control through furnace mouth radiation information fusion. The system comprises a furnace mouth radiation acquisition subsystem, an optical fiber spectrum division multiplexing subsystem, a multi-spectral combined detection subsystem, a furnace mouth flame video acquisition subsystem and a comprehensive determinationsubsystem, wherein the furnace mouth radiation acquisition subsystem is connected with the optical fiber spectrum division multiplexing subsystem; the optical fiber spectrum division multiplexing subsystem is connected with the multi-spectral combined detection subsystem; the multi-spectral combined detection subsystem is connected with the comprehensive determination subsystem through a serial port; and the furnace mouth flame video acquisition subsystem comprises a CCD camera provided with an optical lens and a video capture board, the CCD camera is arranged on the furnace mouth radiation acquisition subsystem and is connected with the video capture board, and the video capture board is connected with the comprehensive determination subsystem. The system and the method achieve a long-range detection (20 meters), so the system can work normally under a severe environment of steel-making without using a fussy cooling device and a dust collector.
