Abstract

SE MIDE LA IMPEDANCIA DE LA CIRCULACION DE FLUIDO EN UNA LINEA DE SUMINISTRO DE FLUIDO. SE UTILIZAN DOS TECNICAS DEPENDIENDO DE LA TASA DE CIRCULACION SELECCIONADA. PARA TASAS ALTAS, LA BOMBA (18) SE CONTROLA PARA VARIAR LA TASA DE CIRCULACION Y SE DIVIDE EL CAMBIO EN LA PRESION MEDIANTE EL CAMBIO DE PRESION PARA DETERMINAR DE FORMA DIRECTA LA RESISTENCIA. PARA TASAS BAJAS DE CIRCULACION, UN PROCESADOR (14) CONTROLA LA BOMBA (18) PARA QUE BOMBEE CANTIDADES DE FLUJO DE ACUERDO CON UN CODIGO BINARIO SEUDO-RANDOMIZADO. LA SEÑAL DE PRESION RESULTANTE PERCIBIDA EN EL CONDUCTO (22) SE DECODIFICA DE ACUERDO CON ESE CODIGO. LAS PRESIONES RECIBIDAS DURANTE LOS PERIODOS DE CODIGOS DE NO CIRCULACION SON SUSTRAIDAS DE LAS PRESIONES RECIBIDAS DURANTE LOS PERIODOS DE CODIGO DE CIRCULACION. TAMBIEN SE RETIRA LA COMPENSACION DE PRESION Y SE USA AL MENOS LA ESTIMACION DE LOS CUADROS CON UN MODELO DE PREDICCION LINEAL PARA DETERMINAR LA IMPEDANCIA. LOS COEFICIENTES DETERMINADOS EN EL MODELO SE UTILIZAN PARACALCULAR LA RESISTENCIA AL FLUJO DE CIRCULACION DEL SISTEMA. UN SUPERVISOR DE CALIDAD CONTROLA EL PROCESO DE DETERMINACION DE RESISTENCIA Y CONTROLA LA VISUALIZACION (28) DE LA RESISTENCIA DEPENDIENDO DE LA CALIDAD DETERMINADA. UN VISUALIZADOR DE RESISTENCIA (28) VISUALIZA DE FORMA CONTINUA LA RESISTENCIA DEL SISTEMA.
