摘要
在航空、航天以及工业控制领域,为提高系统的可靠性及容错能力,会对关键信号采用冗余设计,而双余度信号则是经常使用的一种冗余策略。文中介绍了一种双余度处理技术,同时为减少系统开发成本,设计采用了软件的故障注入技术,并通过软件故障注入技术对该处理技术进行验证,验证结果表明,该处理技术是有效、可行的。
In the fields of aviation, aerospace, and industrial control, in order to improve system reliability and fault tolerance, redundant design is necessary for key signals, dual redundant signal being an often used redun- dancy strategy. This paper introduces a dual redundant processing technology, and at the same time in order to re- duce the cost of system development, the design uses a software fault injection technology to authenticate and verify the processing technology. The results show that th~ t^t~hni^f,,= ;~ J~~. ~ c___：tl
