基于智能运维系统列车跳站问题研究

Research on Train Skip-stop Based on Intelligent Operation and Maintenance System

现代城市轨道交通是一个复杂的系统,自动化程度日益提高,并朝着智能化、集成化、模块化的方向发展。车辆作为城市轨道交通的重要载体,在运营过程中一旦发生故障,将直接影响交通,延误车辆运营计划,严重时会危及乘客安全,扰乱公共秩序。2021年,国务院印发了《交通强国建设纲要》,提出大力发展智慧交通,构建安全、便捷、高效、绿色、经济的现代化综合交通体系。轨道交通车辆智能运维系统可以实现实时监控、故障诊断、健康管理、统计分析等功能,对车辆的安全运行有着重大的意义。本文基于智能运维系统,结合某线路的实际数据,针对下一站ID变化时刻与下一站最大距离变化时刻不同步的问题,提出根据下一站ID的取值以及进站前-出站后阶段使用站间距的方法,解决智能运维系统中车辆在站点图上实时准确显示的问题,通过对比可知,基于下一站ID的列车跳站研究方法具有较强的先进性,准确性更高。研究表明,此方法具有很好的实际应用价值,可以推广到其它地铁线路中应用。

Modern urban rail transit is a complex system with increasing degree of automation and developing towards intelligence,integration and modularization.As an important carrier of urban rail transit,once the vehicle fails in the operation process,it will directly affect the traffic,delay the operation plan,and even endanger the safety of passengers and disturb the public order.In 2021,the State Council issued the“Outline for Building a Strong Transportation Country”,proposing to vigorously develop intelligent transportation and build a safe、convenient、efficient、green and economical modern comprehensive transportation system.The intelligent operation and maintenance system of rail transit vehicles can realize the functions of real-time monitoring,fault diagnosis,health management,statistical analysis and so on,which is of great significance to the safe operation of vehicles.On this basis,combined with the actual data of a certain line,in view of the problem that the change time of the next station ID is out of sync with the change time of the maximum distance of the next station,this paper puts forward the method according to the value of the next station ID and the use of station spacing before entering the station and after leaving the station to ensure the real-time and accurate display of the vehicles on the station map in the intelligent operation and maintenance system.By comparison,it can be seen that the research method of train skip-stop based on the next station ID is much more advanced and accurate with good practical application,and can be extended to other subway lines.
