无人机飞行试验的故障分析需要完整记录无人机飞行状态及环境信息,为此设计了能够记录无人机飞行数据和飞行图像的机载综合记录仪,并解决了各种信息的同步记录和回放问题。同时为满足无人机特殊的使用环境,对记录仪进行了小型化、减重设计及电磁兼容设计。试验表明,数据记录仪不仅满足了系统高速性、实时性、可靠性及体积小等要求,而且还具有结构简约和成本低的优点。
The failure analysis of UAV flight test needs to record the flight status and environmental information of UAV completely. Therefore, an airborne integrated recorder capable of recording UAV flight data and flight images has been designed and a synchronous record of various information has been solved And playback problems. At the same time to meet the special UAV use of the environment, the recorder was miniaturized, weight-loss design and design of electromagnetic compatibility. The test shows that the data logger not only meets the requirements of high speed, real time, reliability and small size, but also has the advantages of simple structure and low cost.
