Abstract

LA INVENCION SE REFIERE A UNA INSTALACION ELECTRONICA PARA SUPERVISION DE ARTICULO, CON UN EMISOR, QUE RADIA UN CAMPO MAGNETICO DE FRECUENCIA DE EMISION VARIABLE POR MEDIO DE UNA ANTENA (4) DE EMISION EN UNA ZONA DE SUPERVISION, Y UN RECEPTOR PROVISTO CON UNA ANTENA (6) DE RECEPCION, CUYA SEÑAL DE SALIDA SE ADICIONA A UN DISPOSITIVO (8) DE DETECCION, QUE ACTIVA UNA SEÑAL DE ALARMA EN LA PRESENCIA DE UNA APLICACION (5) DE DEPENDENCIA DE SEGURIDAD EN LA ZONA DE SUPERVISION, DONDE LA APLICACION (5) DE DEPENDENCIA DE SEGURIDAD CONTIENE UN CIRCUITO DE OSCILACION DE RESONANCIA. PARA LA MEJORA DE LA SEGURIDAD DE PERTURBACION Y DE LA PROBABILIDAD DE COMPROBACION SE PROPONE, QUE SE VALORE TANTO LA AMPLITUD DE LAS SEÑALES DE RECEPCION COMO TAMBIEN LA DIFERENCIA DE FASE ENTRE EL CAMPO DEL EMISOR Y LAS SEÑALES RECIBIDAS.
