Abstract

UN SISTEMA DE CONTROL DEL DESPLAZAMIENTO DE UN ASCENSOR HIDRAULICO CALCULA UNA DISTANCIA DE DECELERACION PARTIENDO DE LA VELOCIDAD DEL ASCENSOR E INICIA LA FASE DE DECELERACION DEL DESPLAZAMIENTO DEL ASCENSOR AL ALCANZAR ESTE LA DISTANCIA CALCULADA DESDE EL RELLANO. EN UNA VERSION PARTICULAR, EL SISTEMA DE CONTROL INCLUYE UNA VALVULA HIDRAULICA (38), UN CODIFICADOR DE ESPACIO (16) Y UN CONTROLADOR (42). EL CODIFICADOR DE ESPACIO (16) MIDE LA VELOCIDAD Y LA POSICION. EL CONTROLADOR (42) UTILIZA LOS DATOS DE VELOCIDAD PARA DETERMINAR LA DISTANCIA DE DECELERACION Y, AL ALCANZAR LA CABINA DEL ASCENSOR (14) LA DISTANCIA CALCULADA DESDE EL RELLANO, MEDIDA DE ACUERDO CON LOS DATOS DE POSICION DEL CODIFICADOR DE ESPACIO (16), ACTIVA LA VALVULA HIDRAULICA (38) E INICIA LA FASE DE DECELERACION. EN UNA VERSION ALTERNATIVA, UNA INTERFAZ (56) INTERCALADA ENTRE EL CONTROLADOR (43) Y LA VALVULA HIDRAULICA CALCULA UN RETARDO ENTRE LA ORDEN DE DECELERACION BASADA EN UNA DISTANCIA PREDETERMINADA Y LA DISTANCIA DE DECELERACION CALCULADA EN FUNCION DE LA VELOCIDAD DE LA CABINA. UNA VEZ TERMINADO EL TIEMPO DE RETARDO, LA INTERFAZ (56) ACTIVA LA VALVULA HIDRAULICA E INICIA LA FASE DE DECELERACION.
