| 摘 要： | 基于linux系统的软件故障注入方法,设计了一个软件故障注入系统UAVFI_L,采用硬件覆盖和故障模型的方法,模拟无人机系统的硬件故障,并着重讨论了在总线上注入故障的试验策略。最后用一台工控机和飞控计算机通讯,注入故障。故障注入试验结果表明了这种方案的正确性和可行性。

| Abstract: | A fault injection system UAVFI_L is developed for an unmanned aerial vehicle using a software based fault injection technique under the Linux.Hardware coverage and failure model are adopted to simulate hardware failures in the unmanned aerial vehicle(UAVFI_L)and a test strategy of bus-level failure injection is discussed in details.A computer for industrial control and a computer for flight control are used for data communication in test.The results of an UAVFI_L dynamic fault injection test showed the validity and practicability of this technique. |
