摘要:

为实现飞行试验机载网络数据实时处理,对动态数据接口、机载网络数据传输结构和实时数据解析方法进行研究,开发基于VC+ 的实时处理软件系统。根据数据采集系统生成的硬件配置文件建立动态数据接口与硬件进行连接,在此基础上利用网络套接字方法对实时传输的网络数据进行捕获,将捕获的网络数据结合结构参数信息进行解析处理,实现机载网络数据的实时处理。此软件系统已在某项目上进行测试并得到成功应用,实践证明此软件系统能够对机载网络数据形象准确的真实解析,进行数据有效性检查、数据采集与记录等方面的实时处理,同时为系统架构扩展和进行深一层的研究提供了科学保障。

Abstract:

For the realization of the airborne network data real-time processing in flight-test, the real-time dynamic data interface, the structure of the airborne network data transmission and the real-time data parsing method are studied,develops the real-time processing software system based on vc+ . Establishs the dynamic data interface with the hardware connection based on Xidml file generated the data acquisition system , uses the method of socket to capture the real-time transmission of network data on the basis of which, parsing processes the capture network data in combination with structure parameter information, realizes the airborne network data real-time processing.This processing system has been conducted on a project test and gets the successful application, the practice shows that this processing system can parse the airborne network data accurately,for data validity checked data storage and recording of real-time processing,for the system architecture extension and deep layer research provides a scientific guarantee.
