Abstract

UN SISTEMA DETECTOR DE DISTANCIAS (10) QUE INCLUYE UN TRANSDUCTOR ULTRASONICO (XM1), UN TRANSCEPTOR (12) Y UNA UNIDAD DE TRATAMIENTO DE SEÑALES BASADA EN UN MICROCONTROLADOR (14). EL TRANSDUCTOR (12) GENERA PERIODICAMENTE Y DIRIGE HACIA EL TERRENO UNA SEÑAL ULTRASONICA DE DOS FRECUENCIAS. LAS SEÑALES DE ECO DE LA TIERRA Y/O DE CUALQUIER COSECHA O DESECHO QUE PUDIERAN INTERVENIR SE VUELVEN A REFLEJAR EN EL TRANSDUCTOR (12) Y A CONTINUACION SON TRATADAS. EL SISTEMA GENERA SEÑALES ENVOLVENTES DE ECO AMPLIFICADAS Y FILTRADAS. LOS TIEMPOS DE ESTABLECIMIENTO Y DE FIN NOMINAL SE DETERMINAN COMO LAS VECES QUE LAS SEÑALES DE ECO ATRAVIESAN UN VALOR UMBRAL QUE ES UNA CIERTA PROPORCION DE UN VALOR DE AMPLITUD MAXIMO DEL ECO. SE DERIVA UN VALOR DE DISTANCIA CERCANA A PARTIR DEL TIEMPO DE ESTABLECIMIENTO DEL PRIMER ECO QUE SOBREPASA UNA AMPLITUD MINIMA. SE DERIVA UN VALOR DE DISTANCIA LEJANA COMO EL TIEMPO DE FIN NOMINAL DE LA ULTIMA SEÑAL DE ECO QUE TENGA UNA AMPLITUD QUE SOBREPASE UN CIERTO VALOR. SEDERIVAN MULTIPLES VALORES DE AMPLITUD Y DE TIEMPO DE ECO A PARTIR DEL ECO DE MAXIMA AMPLITUD. ESTOS VALORES SE UTILIZAN PARA EVITAR QUE LOS ECOS QUE TIENEN LUGAR TRAS EL TIEMPO DE ECO MULTIPLE CON MENOS DE UNA CIERTA AMPLITUD SE UTILICEN PARA DETERMINAR EL VALOR DE DISTANCIA LEJANA. ESTE VALOR DE DISTANCIA LEJANA REPRESENTA LA DISTANCIA A LA TIERRA Y LOS ECOS MAS DEBILES Y ANTERIORES DE LOS DESECHOS O COSECHAS Y LOS ECOS MULTIPLES Y POSTERIORES SE PUEDEN IGNORAR.
