Abstract

Abstract: Firstly, this paper analyzes the influence of networking changes of transmission system caused by new transmission equipment on the existing clock synchronization system, and proposes two synchronization network schemes by combination with long and important main line (Jining-Tongliao railway). Finally, from the perspectives of safety, reliability, operation and maintenance management and so on, this paper carries on the analysis and comparison, and chooses an optimal scheme of physical fusion of one clock and time synchronization networks.

Key words: clock synchronization, time synchronization, SSU-T, LPR

摘要： 首先分析新增传输设备等引起传输系统组网变化后对既有时钟同步系统的影响，并结合长大干线-集通线提出两种同步网方案。最后从安全可靠性、运维管理等角度进行分析比较，选出一种时钟和时间同步两网物理融合的最优方案。
