摘　　要：飞机黑匣子在航空事故调查中具有重要作用,但是其往往难以寻找或者损毁严重。因此,提出了无线黑匣子实时数据传输系统,将黑匣子中记录的数据实时传输到地面站中进行备份。具体的,提出了一个集中式的数据传输架构,利用飞机间多跳传输网络来减少卫星的使用量,并在此基础上设计了一个统一的路由优化算法来决策数据路由方式。最后,基于实际飞机轨迹数据进行了系统仿真,实验结果验证了方法的可行性。Flight Recorder plays a crucial role in air-crash investigation, and however it is not always locatable or even seriously damaged in the flight accident. It is proposed to design a wireless flight-recorder data transmission system, which could transmit the data to a ground center for a real-time backup. Specifically, centralized data transmission architecture is proposed, which could reduce the use of satellites by using multi-hop transmission networks of between aircrafts. Based on this, a unified route optimization algorithm is designed, thus to decide the way of data routing. Finally, the system simulation based on the actual aircraft trajectory data verifies the feasibility of this method.
