Abstract

DISPOSITIVO ACUSTICO DE VIGILANCIA DE UNA INSTALACION INDUSTRIAL PARA LA DETECCION DE CHOQUES EVENTUALES DE CUERPOS EN MIGRACION EN LA INSTALACION. SE FUNDAMENTA EN LA UTILIZACION DE CAPTADORES ACUSTICOS DE ONDAS EMITIDAS EN EL CURSO DE LOS CHOQUES DE LOS CUERPOS MIGRANTES. INCLUYE UN CONJUNTO DE DOS CAPTADORES ACUSTICOS (3, 4) DISPUESTOS EN CONTACTO CON LA PARED DE LA INSTALACION O EN SU PROXIMIDAD, EN LOS PUNTOS DIFERENTES DE LA INSTALACION ENTRE LOS CUALES SE QUIERE EFECTUAR LA VIGILANCIA. ESTOS CAPTADORES ESTAN UNIDOS A UNA CADENA DE MEDIDA Y DE ALARMA A TRAVES DE AMPLIFICADORES (5,6). POR OTRA PARTE, UNOS MEDIOS DE MEDIDA (8) CONTROLAN LA SEPARACION, A LO LARGO DEL TIEMPO, ENTRE LA RECEPCION DE LAS ONDAS ACUSTICAS.
