Abstract

SE DESCRIBE UN SISTEMA DE RADIOALARMA, COMPUESTO DE UNA CENTRAL (1) CON UNA UNIDAD DE RECEPCION (2), UN ORDENADOR (3) Y UNA UNIDAD DE EMISION (8), ASI COMO AL MENOS UN SEÑALIZADOR (4) CON UNA UNIDAD DE EMISION (7), UN ORDENADOR (6), UNA UNIDAD DE SEÑALIZACION (5) Y UNA UNIDAD DE RECEPCION (12). LAS UNIDADES DE RECEPCION DE LA CENTRAL Y DEL SEÑALIZADOR ESTAN SINTONIZADAS CON LOS CORRESPONDIENTES UNIDADES DE EMISION. LA UNIDAD DE EMISION (7) DEL SEÑALIZADOR (4) TRANSMITE UNA PRIMERA SEÑAL DE RADIO A LA CENTRAL, QUE ES RECIBIDA POR SU UNIDAD DE RECEPCION (2), Y EN ESTA SE ACTIVA PARA GENERAR UNA SEÑAL DE SOCORRO PARA REPETIR LA PRIMERA SEÑAL DE RADIO POR EL SEÑALIZADOR (4), POR LO QUE UN GENERADOR GENERA UN CODIGO, QUE SE ALMACENA EN LA MEMORIA DEL ORDENADOR (3) Y SE RECURRE A EL PARA EL TRATAMIENTO DE LA SEÑAL DE RADIO QUE ES EMITIDA POR LA CENTRAL. LA SEÑAL DE RADIO ES RECIBIDA POR EL SEÑALIZADOR (4), TRASLADADA A SU ORDENADOR, QUE PREPARA LA SEÑAL DE REPETICION CONSIDERANDO LA UTILIZACION DEL CODIGO RECIBIDO CONJUNTAMENTE POR LA CENTRAL (1), Y LA CUAL ES EMITIDA DESPUES POR LA UNIDAD DE EMISION (7). LA UNIDAD DE RECEPCION (2) DE LA CENTRAL (1) RECIBE LA SEÑAL DE REPETICION Y LA TRANSMITE A CONTINUACION A SU ORDENADOR (3), EN EL CUAL EL CODIGO RECIBIDO ES FILTRADO Y COMPARADO CON AQUEL CODIGO QUE TIENE ALMACENADO EN SU MEMORIA. EN EL CASO DE ALGUNA DIFERENCIA CON EL CODIGO RECIBIDO RESPECTO AL CODIGO ALMACENADO, SE PROVOCA UNA ALARMA DE AVERIA DESDE LA CENTRAL, EN EL QUE EN RELACION A LA IDENTIDAD DE AMBOS CODIGOS, SE ELABORA LA SEÑALIZACION DE ACUERDO CON SU CONTENIDO Y EL ESTADO DE LA CENTRAL.
