Abstract

LA INVENCION SE REFIERE A UN EQUIPO (1) PARA LA DETECCION DE UN ARTICULO PROVISTO CON UN ELEMENTO (2) DE SEGURIDAD ELECTRONICO EN UNA ZONA (3) DE SUPERVISION. EL EQUIPO (1) SE COMPONE AL MENOS DE UN DISPOSITIVO (5) DE EMISION, QUE EMITE UN CAMPO ALTERNO MAGNETICO, QUE EXCITA EL ELEMENTO (2) DE SEGURIDAD ELECTRONICO PARA LA EMISION DE UNA SEÑAL CARACTERISTICA, DISPONIENDO AL MENOS DE UN DISPOSITIVO (6) DE RECEPCION, QUE CUANDO SE RECIBE LA SEÑAL CARACTERISTICA DISPARA UNA ALARMA. PARA PODER EXTENDER LA ANCHURA DE PASO DE LA ZONA (3) DE SUPERVISION CON PARAMETROS DE IGUALES CARACTERISTICAS, SE PROPONE DE ACUERDO CON LA INVENCION, QUE EL DISPOSITIVO (5) DE EMISION MUESTRE UNA BOBINA CON MULTIPLES ARROLLAMIENTOS (12), QUE LOS ARROLLAMIENTOS (12) SE DISPONGAN ESENCIALMENTE EN UN PLANO Y QUE ESTOS ARROLLAMIENTOS (12) SE SUBDIVIDAN EN AL MENOS DOS GRUPOS (13A, 13B), DONDE (AMBOS) GRUPOS (13A, 13B) SE DISPONEN POR MEDIO DE UN VACIO (15) UNO CON OTRO.THE INVENTION REFERS TO A KIT (1) FOR THE DETECTION OF AN ITEM PROVIDED WITH AN ELECTRONIC SECURITY ELEMENT (2) IN A SUPERVISION AREA (3). THE EQUIPMENT (1) IS COMPOSED OF AT LEAST ONE EMISSION DEVICE (5), THAT ISSUES AN ALTERNATE MAGNETIC FIELD, THAT EXCITES THE ELECTRONIC SECURITY ELEMENT (2) FOR THE EMISSION OF A CHARACTERISTIC SIGNAL, PROVIDING AT LEAST ONE DEVICE ( 6) OF RECEPTION, THAT WHEN THE CHARACTERISTIC SIGNAL IS RECEIVED, AN ALARM SHOOTS. TO BE ABLE TO EXTEND THE PASSAGE WIDTH OF THE SUPERVISION ZONE (3) WITH PARAMETERS OF THE SAME FEATURES, IT IS PROPOSED IN ACCORDANCE WITH THE INVENTION THAT THE EMISSION DEVICE (5) SHOW A COIL WITH MULTIPLE WINDINGS (12), THAT THE ROLLS (12) ARE ESSENTIALLY DISPOSED ON A PLANE AND THAT THESE DEVELOPMENTS (12) ARE SUBDIVIDED IN AT LEAST TWO GROUPS (13A, 13B), WHERE (BOTH) GROUPS (13A, 13B) ARE DISPOSED THROUGH A VACUUM (15) ONE WITH ANOTHER.
