Abstract

METODO Y APARATO PARA LOCALIZAR UNA FUGA PRODUCTORA DE EMISIONES ACUSTICAS CONTINUAS QUE TIENEN RUIDO DE FONDO Y CRESTAS AGUDAS, BASADOS EN VIGILAR CONTINUAMENTE LAS EMISIONES ACUSTICAS MEDIANTE EL USO DE UNOS DETECTORES DISTANCIADOS ENTRE SI QUE PRODUCEN SEÑALES CON UN RUIDO DE FONDO Y UNAS CRESTAS AGUDAS QUE SE CORRESPONDEN CON EL RUIDO DE FONDO Y LAS CRESTAS AGUDAS DE LAS EMISIONES ACUSTICAS CONTINUAS. LAS CRESTAS AGUDAS DE UNA DE LAS SEÑALES ESTAN DESVIADAS EN EL TIEMPO CON RESPECTO A LAS CRESTAS AGUDAS DE LA OTRA SEÑAL, DESVIACION QUE CORRESPONDE A LA DIFERENCIA DE TIEMPO DE PROPAGACION DE LAS SEÑALES ACUSTICAS HASTA CADA UNO DE LOS DETECTORES. MIDIENDO LA DESVIACION ENTRE LAS CRESTAS AGUDAS ES POSIBLE DETERMINAR LA POSICION RELATIVA DE LA EMISION ACUSTICA, Y POR TANTO LA POSICION RELATIVA DE LA FUGA, CON RESPECTO A LA POSICION DE LOS DETECTORES. PARA FACILITAR LA SEPARACION DE LAS CRESTAS AGUDASRESPECTO DEL RUIDO DE FONDO, SE APLICA UN VALOR DE UMBRAL FLOTANTE DE DETECCION A LAS SEÑALES PARA ELIMINAR EL RUIDO DE FONDO.
