Abstract

SE DESCRIBE UN SISTEMA ELECTRONICO DE INTERROGACION E IDENTIFICACION (I/I) EN EL QUE UNA UNIDAD INTERROGADORA/LECTORA (I/R) (12) OPERA A DISTANCIA USANDO UN HAZ DE MICROONDAS (16, 70) EN UNION CON UNO O MAS ARTICULOS (30). LOS ARTICULOS SE IDENTIFICAN POR UN METODO UNICO Y UNA SECUENCIA DE BUSQUEDA UNICA. CUANDO LA UNIDAD (I/R) INTERROGA AL ARTICULO, UNO O MAS DE ELLOS RESPONDE A LA UNIDAD I/R SIEMPRE QUE UN PALABRA DE CODIGO (VALOR DE DATO) ENVIADA DESDE LAS UNIDADES I/R SE ADAPTA A UNA PALABRA DE CODIGO ALMACENADA EN UNO O MAS DE LA POSICION DE MEMORIA (54) DENTRO DE LOS ARTICULOS. DESPUES DE BUSCAR A TRAVES DE TODAS LAS PALABRAS DE CODIGO POSIBLES Y POSICIONES DE PALABRA LA UNIDAD DE I/R HABRAN IDENTIFICADO AL MENOS UN PALABRA DE CODIGO ALMACENADA EN CADA UNA DE LAS POSICIONES DE PALABRA DE AL MENOS UN ARTICULO. ENTONCES LAS COMBINACIONES DE PALABRAS DE CODIGO RECIEN IDENTIFICADAS SE EMPAREJAN CON LAS PALABRAS ALMACENADAS RESPECTIVAS DE LOS VARIOS ARTICULOS (30). DESPUES DE SE UNICAMENTEIDENTIFICADO CADA ARTICULO (30) SE "DESACCIONADO" PEPIDO POR LA UNIDAD DE I/R Y PERMANECE INACTIVO DE MANERA QUE UNO POR UNO TODOS LOS ARTICULOS RESTANTES (3) SE IDENTIFICAN TAMBIEN.
