Abstract

SE PRESENTA UN METODO DE RESOLUCION DE SEÑALES DE ENTRADA EN UN SISTEMA DE CONTROL DE PROCESOS EN EL QUE CADA UNO DE LOS ORDENADORES DE CONTROL DE PROCESO ACTIVAMENTE REDUNDANTE REALIZA UN PROCESO DE ARBITRAJE COMUN SOBRE LAS SEÑALES DE ENTRADA CORRESPONDIENTES. BLOQUES DE SEÑALES DE ENTRADA CORRESPONDIENTES SON MUTUAMENTE INTERCAMBIADOS POR LOS ORDENADORES DE CONTROL DE PROCESOS ACTIVAMENTE REDUNDANTES, Y SE REALIZA UNA COMPROBACION INICIAL PARA DETERMINAR SI ESTAS SEÑALES DE ENTRADA SON VALIDAS. PARA LAS SEÑALES DE ENTRADA QUE REPRESENTAN VALORES ANALOGOS VALIDOS, SE HACE UNA DETERMINACION DE CUANDO SE HA EXCEDIDO UNA TOLERANCIA PREDEFINIDA ENTRE LAS SEÑALES DE ENTRADA CORRESPONDIENTES EN EL CICLO DE CONTROL DE PROCESO ACTUAL. CUANDO LA TOLERANCIA PREDEFINIDA HA SIDO EXCEDIDA, ENTONCES SE REALIZA UNA COMPROBACION PARA DETERMINAR SI LA TOLERANCIA PREDEFINIDO HABIA SIDO EXCEDIDA EN EL ULTIMO CICLO DE CONTROL DE PROCESO. SI LA TOLERANCIA PREDEFINIDA NO FUE EXCEDIDA EN EL ULTIMO CICLO DE CONTROL DE PROCESO, ENTONCES EL VALOR DE ENTRADA ANALOGO SELECCIONADO DURANTE EL ULTIMO CICLO DE CONTROL DE PROCESO SERA EMPLEADO EN EL CICLO DE CONTROL DE PROCESO ACTUAL. SI LA TOLERANCIA PREDEFINIDO FUE EXCEDIDA EN LOS CICLOS DE CONTROL DE PROCESO TANTO ACTUAL COMO ULTIMO, ENTONCES SE UTILIZARA UN CRITERIO DE MAGNITUD PREDETERMINADO PARA DETERMINAR EL VALOR DE ENTRADA ANALOGA PARA SU USO EN LA TOMA DE DECISIONES DE CONTROL DEL PROCESO. TAMBIEN SE SUMINISTRARA UNA INDICACION EN CADA UNO DE LOS ORDENADORES DE CONTROL ACTIVAMENTE REDUNDANTES PARA IDENTIFICAR CUAL DE LAS SEÑALES DE ENTRADA CORRESPONDIENTES FUE SELECCIONADA POR ESE ORDENADOR DE CONTROL DE PROCESOS.
