Design About the Transformation for Test Installation of New Aircrafts Network Data to PCM Signal

摘要:

简单介绍了PCM规范和新飞机测试改装网络包协议,论述了新飞机测试改装网络数据到PCM/NRZL信号转换的嵌入式设备——PCM生成器的软硬件设计思路以及在新支线客机试飞测试中的应用情况；测试和使用结果表明,新飞机测试改装网络数据到PCM转换设计的思路正确,转换速度、时延满足飞行试验要求。

Abstract:

First introduces PCM standard and test installation of new aircrafts network package protocol. Then explains design about the device for test installation of new aircrafts network data to PCM/NRZL signal transformation——PCM signal producer. Finally introduces its application to the new-lateral-airplane flight test. The result of test and application shows the design about transformation for test installation of new aircrafts network data to PCM/NRZL is correct, transformation speed and delay meet demands for flight test.
