摘　　要：随着航空科学技术的发展,空中飞行试验台的试验参数呈几何级增长,基于脉冲编码调制(PCM)架构的空中飞行试验台测试系统已不能满足不断增长的测量参数要求,需重新设计空中飞行试验台测试系统。本文分析了PCM架构测试系统的特点,并基于成熟的网络化数据采集技术,设计了空中飞行试验台新型网络化测试系统,并详述了构成测试系统的各个子系统。同时,分析了新型网络化测试系统的优势以及新老测试系统的数据延迟问题。实际应用表明,新型网络化测试系统能够满足目前的测试要求。With the development of aviation science and technology, test parameter of the flight test platform exponential growth, test system of flight test platform based on the PCM architecture is unable to meet the growing requirements of the measurement parameter, it need to be redesigned. The paper analyzed the characteristics of PCM architecture test system, and the new network flight test system was designed based on mature network acquisition technology, and detail the subsystems of the new network test system. At the same time, analyzed on the advantages of the new network test system, and the old and new test systems were discussed in the data latency issues. Practical application shows that the new networked test system can meet the current test requirements.
