可靠性是无人机飞行控制器首要的性能要求,文章在民用摄像无人机飞行控制器系统设计中采用了避错与容错并重的设计思路。详细介绍了具体的软、硬件可靠性保障措施,提出了机内自检测系统的构成与实现方案,并介绍了故障分析在保障飞机安全时所起的作用。实际应用表明,所采用的设计思路、保障措施和自检测方案能有效提高飞行控制器的可靠性、保障无人飞机的安全。

Reliability is the most important property of unmanned aerial vehicle (UAV) flight controller. Both fault avoidance and fault toleration are adopted in the engineering to ensure the reliability of a commercial camera UAV flight controller . The techniques in hardware and software design used to improve the reliability of the controller are explained in detail. The formation and realization of built in test (BIT) system for the controller is proposed. The function of faults analysis software in ensuring the craft safety is discussed. Application shows that the methods used here and the proposed BIT system can efectivly improve the reliability of the UAV flight contrtoller and ensure the safty of the craft.
