摘要
介绍了国内外有关同步网的技术发展及应用情况,分析了铁路同步网的现状,指出需要改进或加强的问题;针对时间同步网溯源方式单一、重要时间节点之间缺少高可靠性的地面互联、在线监测手段欠缺等主要问题,结合相关技术标准进行分析,建议构建新型铁路同步网架构及体系,改变既有时频信号溯源方式,实现有效的同步网性能在线监测系统,为全面提升铁路同步网的性能提供了技术方案。
The development and application of related technologies of synchronization network at home and abroad are briefly introduced and the current situation of railway synchronization network is also analyzed.Furthermore,the problems that need to be improved or strengthened are pointed out.Aiming at the main problems such as single traceability mode of time synchronous network,lack of high-performance ground interconnection between important time nodes and lack of online monitoring means,it is proposed to build the framework and architecture of a new type of railway synchronization network based on the analysis of relevant technical standards,hence changing the traceability mode of existing time frequency signal,realizing an effective on-line monitoring system of synchronization network performance,providing a technical scheme for improving technical performance and reliability of railway synchronization network in an all-round way.
