Abstract

Un sistema de vigilancia para vigilar el funcionamiento de un aparato de una instalación dinámica, que comprende: una pluralidad de sensores que miden parámetros de funcionamiento que varían dinámicamente del aparato de la instalación dinámica vigilado, y para generar señales de parámetros eléctricas indicadoras de los parámetros de funcionamiento medidos; medios de procesado electrónico para procesar las señales de parámetros eléctricas y que son capaces de producir con ello una pluralidad de diferentes señales de avería, cada una de las cuales indica, respectivamente, que el aparato de la instalación dinámica vigilado tiene una respectiva de entre una pluralidad de averías; medios de presentación para presentar información de avería a un usuario del sistema de vigilancia, estando controlados los medios de presentación por las señales de avería producidas por los medios de procesado electrónico; en que: los medios de procesadoelectrónicocomparan cada uno de los valores de al menos algunas de las señales de parámetros medidos con los respectivos valores límite previamente definidos almacenados en la memoria por los medios de procesado electrónico, y cuando la comparación muestre que el valor de una señal de parámetro medido esté fuera del respectivo valor límite, los medios de procesado electrónico producen una señal de símbolo de avería básica respectiva, con lo que: los medios de procesado electrónico tienen medios de almacenamiento para almacenar señales eléctricas que funcionan de una manera sincronizada por reloj y almacenan las señales de símbolo de avería básica; los medios de almacenamiento tienen una pluralidad de diferentes lugares de almacenamiento, teniendo cada lugar de almacenamiento una pluralidad de posiciones de almacenamiento para unas predeterminadas de las señales de símbolo de avería básica; y cuando todas las posiciones de almacenamiento deun lugar de almacenamiento sean llenadas por señales de símbolo de avería básica producidas en un intervalo sincronizado por reloj previamente especificado, entonces los medios de procesado electrónico producen una señal de avería de alto nivel, teniendo cada lugar de almacenamiento una señal de avería de alto nivel asociada, haciendo la señal de avería de alto nivel que los medios de presentación presenten un mensaje de avería.
