随着试飞技术的发展,网络化测试技术已经应用到试飞测试工程中,针对该网络化测试系统时间精确同步这一难题,文章设计和构建了基于IEEE1588标准的试飞网络化机载数据采集系统,以及该标准如何在分布式数据采集系统中实现系统的同步采集功能,成功地解决了某工程试飞测试领域中网络化测试系统的时钟精确同步的关键技术。
With the development of flight test technology, the networked test technology has been applied to the test flight test project. In view of this problem of time-accurate synchronization of the networked test system, this paper designs and constructs a test-flight networked airborne data acquisition system based on the IEEE1588 standard, And how the standard can realize the synchronous acquisition of the system in the distributed data acquisition system successfully solved the key technology of accurate clock synchronization of the networked test system in the field of test flight test.
