摘要
针对航空燃油管理计算机系统高安全性与高可靠性的要求,采用双余度热备份技术,设计在一台计算机内部实现关键板卡互为备份的双余度燃油管理计算机系统。在保障系统能够长期持久稳定运行的同时,与传统的双机备份方式相比,具有体积更小、生产成本更低、重构方式更多、响应速度更快等优点。
Aiming at the requirements of high security and reliability of aviation fuel management computer system,designs a dual redundancy fuel management computer system by using dual redundancy hot backup technology,which realizes the backup of key circuit boards in one com.puter.Compared with the traditional two-machine backup mode,it has the advantages of smaller size,lower cost,more reconfiguration modes and faster response speed,while guaranteeing the long-term and stable operation of the system.
