Abstract

APARATO PARA DETERMINAR LA POSICION DE UN VEHICULO MOVIL RESPECTO DE UN DISPOSITIVO MARCADOR DE SITUACION FIJA (10, 20) QUE COMPRENDE UNA BOBINA EXCITADA PARA EMITIR UN CAMPO MAGNETICO COMPUESTO DE LINEA DE FLUJO MAGNETICO QUE SE EXTIENDEN RADIALMENTE Y PRECISAMENTE DESDE LOS EXTREMOS DEL EJE LONGITUDINAL DE BOBINA (12). UNA UNIDAD DETECTORA MONTADA SOBRE EL VEHICULO MOVIL COMPRENDE CUATRO BOBINAS DE DETECCION IDENTICAS (A,B,C,D) QUE RESPONDE CADA UNA A LA FRECUENCIA DEL CAMPO MAGNETICO DEL DISPOSITIVO MARCADOR (10, 20) Y QUE TIENEN CADA UNO UN EJE MAYOR (32). ESTAS BOBINAS DETECTORAS (A;B;C;D) SON SOPORTADAS EN DOS PARES (AB, Y CD) CON EL EJE MAYOR (32) DE LA BOBINA DETECTORA DE CADA PAR (A,B Y C,D) DISPUESTO EN CUALQUIER LADO DE UN PLANO CENTRAL COMUN Y QUE SE EXTIENDE PARALELAMENTE A ESTE, EXTENDIENDOSE ESTE PLANO CENTRAL COMUN TRANSVERSALMENTE AL EJE LONGITUDINAL (12) DE LA BOBINA DE DISPOSITIVO MARCADOR. CADA PAR DE BOBINAS DETECTORAS (A,B, C,D) ESTA DISPUESTO EN UN MODELO X EN EL QUESUS EJES MAYORES (32) SE ATRAVIESAN MEDIANA Y PERPENDICULARMENTE PARA DEFINIR UN CENTRO (40 O 42) PARA EL PAR DE BOBINAS. DOS PARES DE BOBINAS (A,B Y C,D) ESTAN MONTADOS CON SUS CENTROS (40 O 42) SEPARADOS POR UNA DISTANCIA FIJA SOBRE UNA LINEA DE BASE (44) CUYOS EJES MAYORES (32) DE LAS BOBINAS (A,B,C,D) ATRAVIESA EN UN ANGULO DE 45 (GRADOS) . LAS SEÑALES DE POSICION A PARTIR DE LAS BOBINAS DETECTORAS (AB,C,D) SE PROCESAN PARA PRODUCIR VALORES DE COORDINACION X E Y QUE INDICAN LA POSICION RELATIVA DE LA UNIDAD DETECTORA PARA DISPOSITIVO MARCADOR (10, 20). EL DISPOSITIVO MARCADOR (10, 20) PUEDE EXCITARSE INDUCTIVAMENTE DESDE UNA ANTENA (46) SOBRE EL VEHICULO MOVIL.
