Abstract

Se propone un método para proporcionar sincronización en un sistema de adquisición de datos que incluye una pluralidad de unidades de adquisición. Una unidad de adquisición determinada de la pluralidad lleva a cabo las siguientes etapas: recibir un paquete desde otro dispositivo del sistema de adquisición de datos; extraer una información de exactitud de sincronización y una información de reloj de referencia desde el paquete recibido; obtener un primer reloj de referencia en función de la información de reloj de referencia extraída; si la información de exactitud de sincronización extraída indica una exactitud de sincronización mejor que una información de exactitud de sincronización vigente asociada a la unidad de adquisición determinada: tomar el primer reloj de referencia obtenido como un reloj de referencia seleccionado y actualizar la información de exactitud de sincronización vigente para indicar una exactitud de sincronización inferior a la información de exactitud de sincronización extraída.
