摘　　要：为真实模拟单粒子翻转故障,对星载容错技术实现有效验证,本文基于VxWorks嵌入式操作系统提出了一种面向应用任务的软件故障注入方法。该方法结合VxWorks的多任务运行环境和动态加载模块机制,通过用户指令与配置文件结合的方式,能够按照指定时间间隔将故障实时注入测试任务的任务栈、程序计数器、数据段等五个特定区域。硬件开发平台的实验结果表明,该故障注入方法安全可靠,可以作为星载容错机制的可靠性检测手段有效实施。In order to simulate the real Single Event Up（SEU） fault and validate the fault-tolerance technique for on- board computers,this paper proposes a soft-implemented fault injection method for on-board applications on Vx- Works.On the basis of multi-tasking environment and dynamic loading mechanism of VxWorks,user command and configuration file are combined as a method,which can inject faults into five sections of a running task including stack,program counter（PC）,data segment and so on by appointed interval. The result of experiment which is accom- plished on the hardware platform,shows that this fault injection method is safe and reliable enough to test the reli- ability of fault-tolerance technique for on-board applications.
