以合福高铁遇到的信号安全数据网技术标准变化引起现场系统升级问题为例,对新旧信号安全数据网技术标准进行了综合比较分析,提出了对现有信号安全数据网的变化影响,并根据此分析结论对合福高铁实施了信号安全数据网技术升级改造,为以后的高铁信号安全数据网升级改造工作提供参考。
Taking the problem of system upgrade caused by the change of the technical standards of signal safety data network encountered by Hefu High Speed Rail as an example, the technical standards of old and new signal safety data networks are comprehensively analyzed and compared, and the changes of existing signal safety data networks are proposed. According to the conclusion of this analysis, we implemented the signal safety data network technology upgrade to Hefei-Fuzhou High-Speed Rail, which will provide references for the future upgrading and reforming of HSR signal safety data network.
