【摘要】：随着我国城市轨道交通的不断发展,轨道交通线路也越来越多的采取地面和高架的形式,气象条件对轨道交通运行的影响也越来越显著。现有城市轨道交通应对方法主要是通过驾驶员观测和天气预报获取天气情况,由调度员设置临时限速。该方法存在无法准确掌握天气影响程度、较大程度降低了运行效率、自动化水平较低等问题,因此本文通过分析各类天气对城市轨道交通的影响,提出了一种针对城市轨道交通的复杂天气环境应对方法,主要内容包括:(1)分析了几种气象条件对于城市轨道交通的影响,并考虑各类天气的耦合作用,引入安全服务水平(Level of Service of Safety, LOSS)的概念作为复杂天气环境影响的度量,提出了基于层次分析的影响评估方法。(2)为应对各类恶劣天气,基于现有全自动运行系统(Fully Automatic Operation System, FAO),构建了自动天气响应系统(Automatic Weather Response System, AWR)。该系统通过外部天气传感器自动采集线路各个区域以及列车行驶周围的天气信息,通过天气信息汇总系统对各类天气信息进行汇总和上传,通过自动环境监控系统对天气信息进行管理和分析,自动确定管制措施和建议信息。(3)利用实验室现有资源搭建了测试环境,仿真测试了不同天气场景下的自动天气响应系统的主要功能。仿真结果显示,自动天气响应系统可以实现对于天气信息的自动分布式采集、集中管理分析以及管制措施的自动确定。在恶劣天气下,相比于传统方法,列车通行时间缩短。在极端天气下,列车自动进站避灾,天气转好后,列车自动恢复运营,能够保障列车的运营安全和效率。研究结果表明,本文提出的应对方法能够实时掌握露天线路的天气情况和影响程度、提高了列车的运营效率、减少了人为介入,可以很好的支持复杂天气环境下的FAO系统对于列车与线路管理,具有良好的效果。
[Abstract]:With the continuous development of urban rail transit in China, more and more rail transit lines take the form of ground and elevated, and the influence of meteorological conditions on the operation of rail transit is becoming more and more significant. The existing coping methods of urban rail transit are mainly to obtain weather conditions through driver observation and weather forecast, and temporary speed limits are set by dispatchers. This method can not accurately grasp the degree of weather impact, greatly reduces the operational efficiency, low automation level and other problems, so this paper analyzes the impact of various weather on urban rail transit. This paper puts forward a method to deal with the complex weather environment of urban rail transit. The main contents include: 1) the influence of several meteorological conditions on urban rail transit is analyzed, and the coupling effect of various weather conditions is considered. This paper introduces the concept of level of Service of Safety Services (LOSS) as a measure of the impact of complex weather environment, and proposes an impact assessment method based on hierarchical analysis (AHP) to deal with all kinds of severe weather. Based on full Automatic Operation system, an automatic Weather Response system, an automatic weather response system, is constructed. The system automatically collects the weather information in every area of the line and around the train through the external weather sensor, and collects and uploads all kinds of weather information through the weather information summary system. Through the automatic environment monitoring system to manage and analyze the weather information, automatically determine the control measures and suggest information. 3) using the existing resources of the laboratory to build the test environment. The main functions of the automatic weather response system under different weather scenarios are tested by simulation. The simulation results show that the automatic weather response system can realize the automatic distributed collection of weather information, centralized management analysis and automatic determination of control measures. In bad weather, train passage time is shorter than the traditional method. In the extreme weather, the train automatically enters the station to avoid the disaster, after the weather improves, the train automatically resumes the operation, can guarantee the train operation safety and the efficiency. The results show that the method proposed in this paper can grasp the weather situation and influence degree of the open-air line in real time, improve the train operation efficiency, and reduce the human intervention. It can support the FAO system in complex weather environment and has good effect on train and line management.
