Abstract
UN SISTEMA DE TRANSMISION DE DATOS DIGITALES PERMITE QUE EL ORDENADOR CENTRAL SE COMUNIQUE CON UN GRAN NUMERO DE TERMINALES DE DATOS QUE TIENEN FUNCIONES ESPECIFICAS. LA TRANSMISION DESDE EL ORDENADOR CENTRAL TIENE LUGAR A TRAVES DE UN TRANSCEPTOR DE ALTA POTENCIA, DE MEDIA O LARGA DISTANCIA Y A TRAVES DE UN SISTEMA MULTIPLEX A UNO DE UNA SERIE DE DISPOSITIVOS DE COMUNICACION PORTATILES. LOS DISPOSITIVOS DE COMUNICACION CONTIENEN PREFERENTEMENTE FUENTES DE ALIMENTACION INTERNAS, COMO POR EJEMPLO BLOQUES DE PILAS SECAS DE NIQUEL CADMIO RECARGABLES. LOS DISPOSITIVOS SE PUEDEN LLEVAR EN EL CINTURON DE UNA PERSONA O SE PUEDEN MONTAR DENTRO O SOBRE UN VEHICULO DE SERVICIO, POR EJEMPLO, UNA CARRETILLA DE HORQUILLA ELEVADORA PARA UTILIZARLA EN ACTIVIDADES DE ALMACENAJE O UN VEHICULO DE ITINERARIO DE SUMINISTRO DE MERCANCIAS. LOS DISPOSITIVOS DE COMUNICACION ESTAN ADAPTADOS PARA FUNCIONAR COMO DISPOSITIVOS DE RETRANSMISION DE COMUNICACIONES ENTRE EL ORDENADOR CENTRAL Y LOS TERMINALES DE DATOS SELECCIONADOS. CADA DISPOSITIVO DE COMUNICACION INCLUYE UN PRIMER TIPO DE TRANSCEPTOR DE BAJA POTENCIA PARA COMUNICARSE DENTRO DE UN PRIMER CANAL Y A UN NIVEL DE TRANSMISION DE BAJA POTENCIA CON UN NUMERO SELECCIONADO DE TERMINALES DE DATOS QUE TIENEN TAMBIEN TRANSCEPTORES DEL PRIMER TIPO. CADA DISPOSITIVO DE COMUNICACION INCLUYE ADEMAS UN TRANSCEPTOR DE ALTA POTENCIA PARA COMUNICARSE DENTRO DE UN SEGUNDO CANAL CON EL TRANSCEPTOR DEL ORDENADOR CENTRAL. UN CONTROLADOR DE DIRECCIONES ACCIONADO POR UN MICROPROCESADOR PERMITE QUE EL DISPOSITIVO DE COMUNICACION CONTROLE LA COMUNICACION A BAJA POTENCIA ENTRE LOS TERMINALES DE DATOS A BASE DE RECIBIR Y RETRANSMITIR COMUNICACIONES DIRIGIDAS LOCALMENTE. EL CONTROLADOR Y EL PROTOCOLO CONTROLADOR RETRANSMITEN ADEMAS MENSAJES DE DATOS ENTRE EL NIVEL DE COMUNICACION DE BAJA POTENCIA Y EL ORDENADOR CENTRAL. CUANDO SE ENCUENTRA EN FUNCIONAMIENTO , EL DISPOSITIVO RECIBE MENSAJES DE DATOS EN UNO DE LOS TRANSCEPTORES Y LOS TRANSMITE EN EL OTRO. EL DISPOSITIVO DECOMUNICACION PUEDE TENER TAMBIEN UNA CAPACIDAD DE MEMORIA SUFICIENTE COMO PARA PERMITIR UNA TRANSMISION DE DATOS DE TIPO POR LOTES PERIODICOS ENTRE EL ORDENADOR CENTRAL Y EL DISPOSITIVO DE COMUNICACION. LA CAPACIDAD DE PASAR DE UN SISTEMA DE TRANSMISION DE ALTA POTENCIA Y ALTA PRECISION Y ALTO COSTE A UN SISTEMA DE TRANSMISION DE BAJA POTENCIA, POCA PRECISION Y BAJO COSTE EN EL NIVEL EN QUE SE UTILIZAN UN GRAN NUMERO DE DISPOSITIVOS DE TERMINALES DE DATOS PROPORCIONA UNA FLEXIBILIDAD AL SISTEMA A UN COSTE RAZONABLE.
