综合化模块化信息处理平台容错技术研究

Research on Fault-Tolerant Technology of Intergrated Modular Information Processing System

综合化模块化信息处理平台是一个典型的分布式计算机系统,是新一代航电任务系统的中央核心处理系统,具备数据、信号、图形图像视频的综合处理能力。提出了综合化模块化信息处理平台容错技术,重点介绍了综合核心处理机系统容错原理、故障类型、故障检测机制以及故障处理方法。从软硬件系统全面考虑,运用系统容错技术进行错误检测与处理,大大提高了系统运行任务可靠性。

With processing data, signal and image, integrated modular information processor（IM1P） is a distributed computer system and has become a key component of the future aircraft avionics system. A fault-tolerant technology is systemically described, and the fault-type and some methods of the fault-detecting and fault-solving on IMIP are introduced emphatically. With sufficiently taking software and hardware system into account, a system fault-tolerant technology for detecting and managing fault is put forward, which can greatly improve the mission reliability of system.
