摘　　要：在弹载嵌入式软件设计中,需考虑各种故障模式并进行针对性软件容错设计。软件容错设计包含信息容错、时间容错和结构容错。对于实时性系统来说,接口通讯过程中受到干扰等外界因素会出现通讯数据异常的偶发性故障,针对该故障模式,在信息容错的基础上,进一步设计两种软件容错方案,并开展其风险分析。这两种软件容错设计方法的可行性和有效性均在工程实际应用中得到试验验证。In the design of embedded software,various kinds of fault modes should be considered.Software fault tolerant design includes information fault tolerance,time fault tolerance and structure fault tolerance.In terms of real-time system,contingent malfunction of software appears in the communication of interfaces in which abnormal data might be introduced.As to this fault mode,two software design schemes based on information fault tolerance are given,as well as their venture analysis.These two schemes are well used and validated in engineer application.
