Abstract
SISTEMA DE TRANSMISION DE INFORMACION CAPAZ DE OPERAR EN DOS MODOS DE COMUNICACION, ADECUADO PARA TRANSMITIR SEÑALES DE INFORMACION ENTRE UNA UNIDAD DE CONTROL CENTRAL (100,200) Y UN CONJUNTO DE TERMINALES (35). CADA TERMINAL (35) PUEDE SITUARSE EN LOS DIFERENTES ASIENTOS DE PASAJEROS DE UN AVION, TREN, AUTOBUS O SIMILAR. LAS SEÑALES DE CADA TERMINAL (35) A LA UNIDAD DE CONTROL CENTRAL (100,200) SE TRANSMITEN POR MEDIO DE DOS CANALES A TRAVES DEL RESPECTIVO TRANSMISOR (38) Y DE UN CABLE (21). EN UNO DE LOS MODOS DE OPERACION, SE UTILIZA UN CANAL COMO CANAL DE ACCESO AL AZAR, Y EL OTRO SE UTILIZA COMO CANAL DE ELECCION. CUANDO NO SE EFECTUA LA TRANSMISION DE ELECCION, EL CANAL DE ELECCION SE UTILIZA COMO UN SEGUNDO CANAL DE ACCESO AL AZAR, PARA QUE EL SISTEMA PUEDA TRANSMITIR EFICIENTEMENTE EL MAXIMO NUMERO DE SEÑALES DE INFORMACION SOBRE LOS CANALES DE ACCESO AL AZAR.
