Abstract

MECANISMO DETECTOR DE FALLOS PARA SISTEMAS DE CONTROL A BASE DE MICROCONTROLADORES. EL MICROCONTROLADOR RECIBE SEÑALES DE ENTRADA DESDE SENSORES DE ENTRADA Y TRANSMITE SEÑALES DE SALIDA A VALVULAS DE SOLENOIDE DE ACCIONAMIENTO ELECTRICO EN RESPUESTA A LAS SEÑALES DE ENTRADA. UN CONTROLADOR DEL CIRCUITO DE ACCIONAMIENTO ES SENSIBLE A LAS SEÑALES DE SALIDA Y A UNA SEÑAL DE ACTIVACION DE SOLENOIDES GENERADA POR UN CIRCUITO DE VIGILANCIA PARA CONTROLAR LAS VALVULAS DE SOLENOIDE. EL CIRCUITO DE VIGILANCIA ES SENSIBLE A IMPULSOS DE VIGILANCIA GENERADOS POR EL MICROCONTROLADOR Y TRANSMITIDOS A TRAVES DE LA PUERTA DE VIGILANCIA DEL MICROCONTROLADOR, PARA GENERAR LA SEÑAL DE ACTIVACION DE LOS SOLENOIDES. EL CIRCUITO DE VIGILANCIA GENERA LA SEÑAL DE ACTIVACION DE SOLENOIDES UNICAMENTE CUANDO LA FRECUENCIA DE LOS IMPULSOS GENERADOS EN LA PUERTA DE VIGILANCIA SE ENCUENTRA DENTRO DE UNA GAMA DE FRECUENCIA RELATIVAMENTE ESTRECHA. EL CIRCUITO DE VIGILANCIA DESACTIVA POR TANTO A LOS CIRCUITOS DE ACCIONAMIENTO DURANTE EL FALLO DEL MICROCONTROLADOR PARA ASEGURAR QUE LOS SOLENOIDES NO FUNCIONEN.
