高速列车群运营安全保障仿真模拟试验平台设计

Design of the Simulation Platform for Safety Safeguard of High-Speed Trains Operation

基于"主动安全"设计理念,采用Flex与ArcGIS技术,构建可视化、集成化和智能化的高速列车群运营安全保障仿真模拟试验平台。平台通过不同系统之间的信息共享,为高速列车群运营全过程安全行为演化建模、风险评估和预警提供数据支持,实现对高速列车群事故推演和安全态势分析。平台采用分层逻辑结构,从下到上依次为物理层、获取层、数据层、应用层和表示层。平台通过电力线通信、以太网和控制器局域网等从其他系统获取数据,再对数据进行融合与集成,实现信息共享、安全评估与仿真和安全预警等功能。研发的平台在轨道交通控制与安全国家重点实验室进行了成功部署和模拟仿真运行,通过对大量的行车安全信息的获取、传输和共享以及仿真试验证明,平台具有较高的安全性和稳定性,便于管理和维护。

Based on the ＂proactive safety＂ concept,adopting Flex and ArcGIS technology,a visual,integrated and intelligent simulation platform for safety safeguard of high-speed trains operation was proposed in this paper.Through the information sharing between different systems,the platform provided the data support for safety behavior modeling,risk assessment and warning of the whole high-speed railway trains operation so as to realize the accident rehearsal and safety situation analysis of high-speed railway trains.The platform adopted layered logical structure.From bottom to top,it was physical layer,acquisition layer,data layer,application layer and presentation layer.The platform accessed the data through the PLC,Ethernet,and CAN-bus from other systems,then fused and integrated the data,so as to realize the information sharing,safety evaluation and simulation,safety warning and other functions.The developed platform had been successfully deployed and simulated on State Key Laboratory of Rail Traffic Control and Safety.Through a large number of information acquisition,transmission,sharing and simulation experiments,it has proved that the safety and the stability of the platform are higher,and it is easy to manage and maintain.
