Abstract

UN SISTEMA SENSOR DE LA DISTANCIA (10) INCLUYE UN TRANSDUCTOR ULTRASONICO (XM1), UN TRANSRECEPTOR (12) Y UNA UNIDAD DE PROCESO DE SEÑAL BASADA EN UN MICROCONTROLADOR (14). EL TRANSDUCTOR (12) GENERA PERIODICAMENTE Y DIRIGE HACIA EL TERRENO UNA SEÑAL ULTRASONICA DE FRECUENCIA DUAL. SEÑALES DE ECO DESDE EL SUELO Y/O CUALQUIER CULTIVO U HOJARASCA QUE INTERVENGA SON REFLEJADOS EN EL TRANSDUCTOR (12) Y PROCESADOS. EL SISTEMA GENERA SEÑALES DE ENVOLTURA DE ECO AMPLIFICADAS Y FILTRADAS. LOS PERIODOS DE MARGEN DE CABEZA Y RASTREO SON DETERMINADOS COMO LOS PERIODOS QUE LAS SEÑALES DE ECO CRUZAN UN VALOR DE HUMBRAL QUE ES UNA CIERTA PARTE DE UN VALOR DE AMPLITUD DE ECO MAXIMO. SE DERIVA UN VALOR DE DISTANCIA CERCANA DEL PERIODO DE MARGEN EN CABEZA DEL PRIMER ECO QUE EXCEDE UNA AMPLITUD MINIMA. SE DETERMINA UN VALOR DE DISTANCIA LEJANA COMO EL PERIODO DE MARGEN DE RASTREO DE LA ULTIMA SEÑAL DE ECO QUE TIENE UNA AMPLITUD QUE EXCEDE UN CIERTO VALOR. LOS PERIODOS DE ECO MULTIPLES Y LOS VALORES DE AMPLITUD SON DERIVADOS DESDE EL ECO DE MAXIMA AMPLITUD. ESTOS VALORES SON UTILIZADOS PARA PREVENIR ECOS QUE OCURREN DESPUES DE LOS PERIODOS DE ECO MULTIPLES CON MENOS DE UNA CIERTA AMPLITUD, DE SER UTILIZADOS EN LA DETERMINACION DEL VALOR DE LA DISTANCIA MAS LEJANA. ESTE VALOR DE DISTANCIA MAS LEJANA REPRESENTA LA DISTANCIA AL SUELO Y ECOS TEMPRANOS DEBILITADOS DE HOJARASCA Y CULTIVOS, LOS ECOS MULTIPLES SE PUEDEN IGNORAR.
