摘要
通过总结多个工程的建设经验,对我国城市轨道交通综合监控系统的时间同步问题进行3种方案的探讨;根据最佳方案,就如何提高对时精度提出详细的建议。在西安地铁2号线中,采用NTP协议网络对时方式,获得相对精确的时钟信息。
After summarizing the experience of a number of projects, the author discussed three programs of time synchronization for the synthetic supervisory system of urban rail transit. According to the best solution for improving the accuracy of time checking, detailed proposals were put forward. In Xi' an metro Line 2, time-checking approach of NTP protocol has acquired relatively accurate timing information.
