Abstract

EN UN PROCEDIMIENTO PARA CONTROLAR EL ACCESO DE UNA ESTACION DE DATOS A UNA PLURALIDAD DE SOPORTES MOVILES DE DATOS, SE COMPRUEBA SI EN UNA POSICION BINARIA DE LOS NUMEROS DE IDENTIFICACION TRANSMITIDOS EN MODO SINCRONO POR LOS SOPORTES DE DATOS SE RECIBEN DOS VALORES DE BIT DIFERENTES. PARA LA CONTINUACION DEL ARBITRAJE SE SELECCIONAN LOS SOPORTES DE DATOS QUE EN ESA POSICION DE DATOS TIENEN UN VALOR DE BIT ESPECIFICADO POR LA ESTACION DE DATOS EN EL NUMERO DE IDENTIFICACION. LA TRANSMISION DE LOS VALORES BINARIOS DE LOS NUMEROS DE IDENTIFICACION UTILIZA LA MODULACION POR DESPLAZAMIENTO DE FRECUENCIA COMO LA MAS ADECUADA. EN EL APARATO RECEPTOR SE HAN PREVISTO FILTROS PARA SEPARAR LA SEÑAL DE RECEPCION EN LAS FRECUENCIAS ASIGNADAS A LOS VALORES DE BIT PARA RECONOCER LA RECEPCION SIMULTANEA DE VALORES DE BIT DIFERENTES EN UNA POSICION DE BIT.
