Research on simulation scheme of railway passenger station emergency response based on digital twins model

客运站是铁路客运组织的重要场所,客运站内任何突发事件将带来不良社会影响。面对突发事件时,如何确保客运站现有的资源条件和响应机制,能够有效控制事态演化,是目前亟待解决的问题之一。文章在梳理铁路客运站应急响应业务基本流程的基础上,明确应急响应事前、事中、事后的仿真需求;采用数字孪生概念和方法,建立客运站数字孪生应急响应模型,设计客运站应急响应仿真软件主要功能,并重点对大面积晚点、大客流、火灾与暴恐等典型应急场景,细化仿真功能设计,为下一步开发客运站应急响应仿真及能力评估应用奠定基础。

As the passenger stations are key places for railway passenger transport organization,any emergency occurring in the passenger stations will bring adverse social impacts.In the face of emergencies,how to ensure that the existing resource conditions and response mechanism of the passenger station can effectively control the evolution of the situation is one of the urgent problems to be solved.Through analyzing the basic work flow of emergency response operations of the railway passenger station,the simulation requirements of emergency response before,during and after the emergency response are clarified.Then,the digital twins emergency response model of passenger station is established based on the concept and method of digital twins and the main functions of the emergency response simulation software for passenger station are designed.Furthermore,the simulation functions of typical scenarios,many trains delay,large passenger flow,fire and violence,are refined,thus laying a foundation for the further development of the emergency response simulation and capacity assessment application of passenger station.
