等级转换的特殊应用场景分析

Analysis of Special Application Scenario in Level Transition

高速铁路动车组能够根据线路的列控系统等级自动切换车载设备的列控系统等级。在工作中发现等级转换的设计在一些特殊场景中受到某些因素影响,而这些因素在既有原则规范中并未提及或详细说明。通过分析在特殊场景中这些因素的影响范围、与原则规范的关系及克服影响的办法,总结得出可实际应用的新设计建议,并指出等级转换的设计原则在工程项目中需进一步研究完善。

High-speed EMU can realize automatically the level transition of train control onboard equipment according to the level of train control system of the line.The designs of level transition in certain special scenarios are affected by factors which are not mentioned or specified in existing principles or criteria.In this paper,by analyzing the impact of such factors,their relationship with applicable principles and the solutions to withstand such impact,the paper puts forward practical suggestions on new project designs and points out that the existing principles of design should be further studied and improved.
