摘要
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。
In order to analyse＂ the fault or accident of UAV flight test need complete recording of flight da- ta, A comprehensive onboard information recorder is designed to record UAV flight information and flight image. A complete solution is provided to record and replay the information synchronously. Also messures are taken to reduce the size and weight of the recorder, and to enh^mce the electro- magnetic compatibili- ty. Finally the test demonstrated that the requirements, high speed, real time and reliability for instance, were fulfilled. Furthermore, the structure of the recorder is brief and the volume is small, while the cost is lOW.
