Abstract

PARA EL RECONOCIMIENTO RAPIDO DE INTERRUPCIONES DURANTE EL FUNDIDO DE BARRAS SE MIDE, Y A CONTINUACION SE VALORA, LA TEMPERATURA SUPERFICIAL DE LA BARRA CON AYUDA DE SENSORES DE TEMPERATURA DISTRIBUIDOS ALREDEDOR DE LA BARRA EN LA COQUILLA. PARA PODER OBTENER UNA PREDICCION LO MAS EXACTA POSIBLE DE LAS INTERRUPCIONES CON POCO ESFUERZO DE CALCULO SE ASOCIA A CADA SENSOR DE TEMPERATURA (10) UN DISPOSITIVO DE RECONOCIMIENTO DE PATRONES (11), EL CUAL, A PARTIR DE LA TEMPERATURA MEDIDA Y DE UNA VARIABLE INTERNA QUE REPRESENTA Y COMPORTAMIENTO ANTERIOR DE LA TEMPERATURA ACTUALIZA, BASANDOSE EN REGLAS DE LOGICA BORROSA, LA VARIABLE DE ESTADO INTERNA Y GENERA COMO SALIDA UN VALOR ACTUAL DE LA PREDICCION (P{SUB,A}) DE LA PROBABILIDAD DE INTERRUPCION.
