Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA COMUNICACION DE TOLERANCIA DE FALLOS BAJO ALTAS CONDICIONES DE TIEMPO REAL EN UN MECANISMO DE RED LOCAL, DONDE UNA ARQUITECTURA BUS DOBLE SE UTILIZA PARA LA COMUNICACION DE FALLO Y PARA LA TOLERANCIA DEL SENSOR BUS GLOBAL. PARA GARANTIZAR LA CONSISTENCIA EN CASO DE FALLO Y EL MANTENIMIENTO DE LAS DISPOSICIONES DE TIEMPO CON REFERENCIA A LA TRANSMISION DE DATOS SE PROPONE UN MECANISMO DE RECONOCIMIENTO DE FALLOS ACTIVO Y EN LA DIRECCION CORRESPONDIENTE. EN UNO DE LOS SISTEMAS BUS REDUNDANTES SE TRANSMITEN EN OPERACION LIBRE DE FALLO TODOS LOS DATOS DE PROCESO Y EN OTROS SISTEMAS BUS LAS INFORMACIONES SOBRE EL ESTADO CORRESPONDIENTE. CADA BUS SE UTILIZA EN CASO DE FALLO COMO BUS DE OBSERVACION, PARA DISTRIBUIR RESPECTIVAMENTE OTROS FALLOS CORRESPONDIENTES A SISTEMAS BUS A LOS PARTICIPANTES DE RED. EL PROCEDIMIENTO PUEDE SER UTILIZADO EN SISTEMAS DE AUTOMATIZACION Y DE CONDUCCION DE ACUERDO CON EL PROCESO QUE SE CARACTERIZA A TRAVES DE ALTOS REQUERIMIENTOS CON REFERENCIA A LA FIABILIDAD Y AL COMPORTAMIENTO EN TIEMPO REAL.
