针对分布式以太网机载测试系统,实现各系统时钟之间的一致性及稳定性至关重要。本文详细描述了该系统时间在以太网测试系统中的典型应用,进一步对其网络传输协议及数据结构进行分析。引言时钟同步是指将分布在各个位置的时钟与标准时钟对准,以实现系统时间的一致性及准确性。在试飞测试系统中,借助于基准时间源可以将分布在各个位置的采集器、记录器等设备同步运作起来。同步时钟采用IRIG-B作为标准时钟
For distributed Ethernet airborne test system, to achieve consistency and stability between the various system clock is essential. This paper describes in detail the typical application of this system time in Ethernet test system and further analyzes its network transmission protocol and data structure. Introduction Clock synchronization refers to aligning clocks distributed in various locations with standard clocks to achieve consistency and accuracy of system time. In the test flight test system, with the reference time source can be distributed in various locations, collectors, recorders and other equipment to operate simultaneously. Synchronous clock using IRIG-B as a standard clock
