摘要
跨地区远程一体化运行系统,尤其是测量精度要求高的测距系统,不同区域间时间同步精度如何精确的标定评估是系统工程实现过程中必须要解决的重要问题。综合考虑经济成本、实现周期、操作便捷等约束因素,在对目前常用的远程时间同步标定方法进行分析比较的基础上,提出了基于搬运钟的远程时间同步标定试验实现方法,并通过试验验证了方法的可行性,同步测试精度可达到0.108ns。
To the mult iregional long-distance integrat ive function system, especial ly to a region measure system whose measure precision demand is very high, how to demarcate and evaluate accurately the time synchronization performance is very important in system＇s engineering realization. Considering the restriction such as economy cost, realization period, operation handiness, this paper brings forward the realization method of clock travel, basing on analysis and compare of the common used time synchronization performance testing method. It is validated that the method is feasibility and the time synchronization performance testing precision attains 0. 108 ns.
