Abstract

LA PRESENTE INVENCION SE REFIERE A UN SISTEMA DE VIGILANCIA DE ARTICULOS QUE DETECTA LA PRESENCIA EN UNA ZONA DE DETECCION (18) DE ARTICULOS DE INTERES. COMPRENDE AL MENOS UN DISPOSITIVO TRANSMISOR (11, 13) Y UN DISPOSITIVO RECEPTOR (12, 15) DE SEÑALES ELECTROMAGNETICAS DE RADIOFRECUENCIA EN LA ZONA DE DETECCION O EN SU PROXIMIDAD. CADA ARTICULO ESTA PROVISTO DE UN SENSOR O MARCADOR (20) QUE ACTUA COMO TRANSPONDEDOR, TRANSMITIENDO AL RECEPTOR UNA SEÑAL ELECTROMAGNETICA DE RADIOFRECUENCIA DE RESPUESTA CUANDO RECIBE UNA SEÑAL DEL TRANSMISOR. ADEMAS, EL SISTEMA DISPONE DE UNA INSTALACION DE BOBINAS (16) CON SUS ELEMENTOS DE ALIMENTACION (17) QUE GENERA UN CAMPO MAGNETICO DE MODULACION A BAJA FRECUENCIA EN LA ZONA DE DETECCION (18), Y UN CONTROLADOR (14) CONECTADO FUNCIONALMENTE AL TRANSMISOR (11, 13), AL RECEPTOR (12, 15) Y A LA INSTALACION DE BOBINAS (16, 17). CADA SENSOR (20) TRANSMITE UNA SEÑAL DE RESPUESTA CUYA AMPLITUD ESTA MODULADA POR EL CAMPO MAGNETICO Y EL RECEPTOR RECIBE Y DEMODULA DICHA SEÑAL DE RESPUESTA MODULADA EN AMPLITUD. EL CONTROLADOR (14) ALIMENTA CON SEÑALES DE MODULACION (I MOD) LA INSTALACION DE BOBINAS (16, 17), RECIBIENDO LAS SEÑALES DEMODULADAS (I DEMOD ) DEL RECEPTOR (12, 15) QUE UTILIZA CUANDO DETERMINA LA POSICION DEL SENSOR (20) DENTRO DE LA ZONA DE DETECCION (18).
