摘　　要：为验证网络化机载测试系统的基本性能,设计并集成网络化机载数据测试系统,研究测试系统的配置和调试方法,提出网络化机载测试系统的时间精度、同步时间、丢包率、遥测传输等测试原理及方法。通过这些方法可以检查所建立的机载测试系统基本性能,掌握整个测试系统的工作状态,便于后期对测试系统进行更改、扩容等,并为C919大型客机机载测试系统的建立提供依据和参考。To verify the basic fundamental characteristics of network airborne testing system, thispaper designs and integrates the network airborne testing system, and also studies the configurationand debug method of testing system. This paper proposes testing theories and methods for timeprecision, synchronization time, packet loss rate and telemetry transmission of this system. Throughthese methods, the engineers can check the basic capability of the airborne test system, master theworking state of the whole test system, and also make it very easy to upgrade and expand thetesting system in the later period. At the same time, this paper provides basis and references forthe establishment of C919 airborne testing system.
