软件实现的无人机故障注入系统

Fault injection system based on software for unmanned aerial vehicle

结合无人机的特点提出了一种基于软件的无人机故障注入系统实现方案,利用故障注入技术实时地模拟无人机机载设备的故障,演示机载设备在寿命试验中的快速失效过程;并构造了一个实用的故障注入工具UAVFI-01,考察无人机故障检测、隔离及系统重构的能力,测试其可靠性.在无人机动态测试过程中,故障注入试验结果表明了这种方案的正确性和可行性.

A scheme to implement the design of fault injection system based on software in view of the feature of unmanned aerial vehicle（UAV） is presented, by which the fault of airborne equipment in UAV can be simulated in real time, and the speediness invalidation process in life test can also be demonstrated. Then a practical fault injector UAVFI_ 01 is designed and constructed, which is used to test the reliability of UAV and examine the ability of fault detection,fault isolation and system reconstruction. Experiments presented in system dynamic test demonstrate that this scheme is fight and feasible.
