Abstract

EN UN PROCEDIMIENTO PARA DETECTAR PELIGROS EN UNA SALA, DONDE SE ANALIZA LA COMPOSICION DE UNA MEZCLA DE GASES EXPONIENDO LA MEZCLA DE GASES A UNA RADIACION DE BANDA ANCHA DE UNA FUENTE DE RADIACION (18) Y DONDE LOS RAYOS QUE PASAN POR LA MEZCLA DE GAS SON TOMADOS POR VARIOS DETECTORES (22, 24, 28, 30) EN DIFERENTES CAMPOS DE LONGITUD DE ONDAS, SE COMPARAN LAS SEÑALES DE SALIDA DE LOS DETECTORES (22, 24, 28, 30) CON VALORES DE UMBRAL PREVIAMENTE DADOS. ESTOS SON ASIGNADOS A DETERMINADAS CONCENTRACIONES DE GAS EN LA MEZCLA DE GASES Y COMO RESULTADO DE LA COMPARACION SE GENERA UNA MUESTRA BIT (72); VARIAS MUESTRAS BIT DE REFERENCIAS (84A, 84B) SON DISPONIBLES, QUE DEFINEN LAS COMPOSICIONES DE LA MEZCLA DE GASES Y, DEPENDIENDO DE LA COMPARACION DE LA MUESTRA BIT GENERADA (72) CON LAS MUESTRAS BIT DE REFERENCIA (84A, 84B) SE EMITE UNA SEÑAL DE ESTADO (96) QUE MARCA EL ESTADO DEL PELIGRO.
