Resarch on software redundancy design methods of ship computer control system

简要介绍了在舰船计算机测控系统中的软件冗余设计。在设计中采用智能故障诊断和容错技术的设计线路、技术途径、技术方法及避错、容错软件编写的一些原则。主要研究了恢复块及多版本程序设计2种常用的软件冗余设计方法,并就其在分布式系统中应用存在的问题进行简要的分析,提出了软件冗余设计的实际应用,并给出其具体改进方案的设计。

This paper introduces the software redundancy design on the ship＇s computer control system. Using the intelligent fault diagnosis and the fault-tolerant technology during the design of the computer control system, including circuit design, technical approach and the principles about programming fault-tolerant software. Mainly research two popular software redundancy design methods, they are recovery block method and multi-version programming method, then gives the brief analysis of them on the distributed system. At last, takes out the real application of the software redundancy design and gives their specific improvement program designs.
