飞行试验机载网络数据采集与分析技术

飞行试验机载采集系统采用商用网络化体系结构替代原有的专用总线结构后,比传统的采集模式具有传输速率更高、连接简单、维护性强、成本更低等优势,另外采用网络进行连接,也大幅度减少了线缆的重量,从而使被试试验机的重量减少很多,对于飞行试验来说,减少重量意味着进一步保障了试飞安全。简要介绍了机载以太网数据采集的原理,并结合飞行试验实际应用,给出了一种现代飞机飞行试验中机载以太网数据采集和事后网络数据预处理软件的实现技术、系统组成和处理流程。

Acquisition and Analysis of Airborne Network Data in Flight Test

The airborne acquisition system applied to flight test uses commercial network system instead of the special bus structure used before.Compared with the traditional acquisition mode,it has many advantages: high-speed transmission,simple connection,better maintainability and lower cost.In addition,the weight of cable line is reduced due to the network connection.Thereby,the weight of airplane used in flight test can be reduced.It means that the safety of the flight test is ensured.The principle of airborne E...
