摘　　要：针对飞行试验过程中基于以太网络传输的机载数据采集系统,设计了一个基于VC环境下以太网络数据包分析处理软件。该软件对结构化参数信息分析处理,及以TCP,UDP等协议传输的机载采集的网络数据包进行解析处理,同时对不同时间采样的参数数据按照就近方法进行时间统一处理,提供有效的性能和状态数据的分析。经过软件测试后,该软件能够正确的提取参数数据,且效率较好。A kind of Ethernet network data packet analysis software based on VC was designed in allusion to the acquisi- tion system of airborne data transmitted by Ethernet network during flight test. This software analyses and processes the structural parameter information and network data packets acquired by airborne equipment, and transmitted by TCP and UDP protocols. The parameters acquired at different time are processed aecording to proximity principle in time sequence to provide effective performance and state data analysis. The software test results show that the software is able to extract the parameter data correct- ly and moreover it has high efficiency.
