Abstract

SE DESCRIBE UN DISPOSITIVO DE MANDO PARA UN ASCENSOR SIN SENSOR DE VELOCIDAD Y CON UN MOTOR DE INDUCCION (3) QUE ACCIONA LA CABINA DEL ASCENSOR (5) Y QUE, A PARTIR DE UNA MARCA DE INDICACION PREVIA (7), DESACELERA LA MARCHA PARA CONDUCIR LA CABINA DESPACIO HASTA EL NIVEL DE PISO INDICADO POR OTRA MARCA (8). LA ALIMENTACION ELECTRICA DEL MOTOR DE INDUCCION (3) SE EFECTUA MEDIANTE UN INVERSOR VVVF (2). EL INVERSOR VVVF (2) MIDE LA CORRIENTE EFECTIVA (1A) CONDUCIDA AL MOTOR DE INDUCCION (3), MIENTRAS LA CABINA (5) AVANZA CON VELOCIDAD CONSTANTE, ES DECIR, ANTES DE QUE ALCANCE LA MARCA PREVIA (7). UNA UNIDAD COMPENSADORA DE RESBALAMIENTO (13) DEDUCE DE LA CORRIENTE EFECTIVA UNA FRECUENCIA DE RESBALAMIENTO CORRESPONDIENTE Y DE ESTA DERIVA UNA FRECUENCIA TEORICA DEL ESTATOR PARA LA FASE DE MARCHA LENTA HASTA LA MARCA (8). EN UNA MEMORIA (11) SE ALMACENA UNA FUNCION INDICADORA DEL INTERVALO DE MARCHA LENTA (TC) EN DEPENDENCIA DE LA CORRIENTE EFECTIVA MEDIDA. UNA UNIDAD PROCESADORA (12) CALCULA A BASE DEL INTERVALO DE MARCHA LENTA (TC) UN INTERVALO DE RETARDO (TD) POR EL QUE SE RETRASA DE UN RECORRIDO A OTRO EL INICIO DEL PROCESO DE FRENADO DE LA CABINA (5), Y DEDUCE MEDIANTE EL INTERVALO DE RETARDO (TD) DESPUES DE CADA RECORRIDO UN NUEVO INTERVALO VIRTUAL DE MARCHA LENTA (TCV). FINALMENTE, EL INVERSOR VVVF (2) SE MANEJA POR UN GENERADOR DE PERFIL (1) MEDIANTE UNA SEÑAL DE TENSION/FRECUENCIA (F,U) QUE DEPENDE DEL INTERVALO VIRTUAL DE MARCHA LENTA (TCV).
