Abstract

PARA LA COMUNICACION DE DATOS DIGITAL ENTRE UN VEHICULO (TRANSPONDER) Y UNA BALIZA SE PROPONE UNA REGULACION DE AMPLIFICACION CON UNA UNIDAD DE CONTROL DE GANANCIA EN DONDE LA ATENUACION DE VIA ENTRE EL TRANSPONDER Y LA BALIZA SE INCREMENTAN DE FORMA SUPERPROPORCIONAL CON LA DISTANCIA. PARA LA GANANCIA DE CONTROL SE PROPONE UNA UNIDAD EN DOS ETAPAS. DESPUES DE LA PRIMERA ETAPA, LA SEÑAL DE SALIDA SE MIDE Y SE GUIA, CONJUNTAMENTE CON UN VALOR DE REFERENCIA A PARTIR DE UN VALOR DE REFERENCIA, A UN AMPLIFICADOR DE CONTROL DE GANANCIA AUTOMATICO. LA SEÑAL DE SALIDA A PARTIR DE ESTE AMPLIFICADOR SE UTILIZA PARA EL CONTROL TANTO DE LA PRIMERA COMO DE LA SEGUNDA ETAPA DE AMPLIFICACION. ESTE CONTROL DE GANANCIA HACE POSIBLE, POR EJEMPLO, MONITORIZAR SOLAMENTE UNA VIA EN UN SISTEMA PARA CARGO AUTOMATICO DE PEAJE DE AUTOPISTA PARA UN VEHICULO. SE ELIMINAN LOS EFECTOS DEBIDO A OTROS VEHICULOS QUE VIAJAN EN VIAS ADYACENTES.
