【摘要】：安全作為運營工作的主線,貫穿于鐵路運輸整個過程,是工作人員及社會大眾關(guān)注的焦點。近年來,隨著高速鐵路的快速發(fā)展,其運營里程達到世界第一的同時,線網(wǎng)規(guī)模也在日益擴大。然而在世人為高速鐵路跨越式發(fā)展歡呼喝彩的同時,高速鐵路運營安全問題也被提上日程。由于高速鐵路系統(tǒng)龐大復(fù)雜,涉及的車、機、工、電、輛等眾多部門,因此,其在人員、設(shè)備、環(huán)境、管理方面存在的風(fēng)險源也日趨增多。為應(yīng)對高速鐵路運營過程中的突發(fā)事故,本文對高速鐵路運營過程中的安全風(fēng)險因子進行識別與預(yù)警研究,運用系統(tǒng)的方法識別風(fēng)險因子,建立風(fēng)險因子指標(biāo)體系,并進行相關(guān)性分析,確定影響最大的因子,構(gòu)建預(yù)警管理系統(tǒng),為進一步保障高速鐵路運營過程安全提供實際的理論參考與應(yīng)用意義。本論文的研究工作主要包括如下幾方面:(1)構(gòu)建了高速鐵路運營過程安全鏈條模型�；谔肪值膶嵉卣{(diào)研分析,確定高鐵運營安全的定義以及目標(biāo),同時在對高速鐵路運行過程分析的基礎(chǔ)上,從線路基礎(chǔ)、運行調(diào)度以及運營控制三大環(huán)節(jié)著手,建立了高速鐵路安全鏈條模型,并對高速鐵路安全鏈條模型四大單元(調(diào)度中心、線路基礎(chǔ)、列控中心、列車運行系統(tǒng))進行詳細(xì)分析,確定各單元的安全鏈條節(jié)點,從而進一步提出高速鐵路安全鏈條模型的應(yīng)用。(2)分析了高速鐵路運營過程安全風(fēng)險因子,建立了安全風(fēng)險指標(biāo)體系�；诎踩湕l模型,通過HAZOP分析方法,從“人 設(shè)備 環(huán)境 管理”四方面對高速鐵路運營過程安全風(fēng)險因子進行分析及確定,同時運用粗集理論對安全風(fēng)險因子進行屬性約簡及提取,最終進行安全風(fēng)險指標(biāo)體的優(yōu)化。(3)對高速鐵路運營過程安全風(fēng)險指標(biāo)體系因子進行相關(guān)性分析。針對安全風(fēng)險因子核心指標(biāo)體系設(shè)計調(diào)查問卷,獲取樣本數(shù)據(jù),并通過信度與效度分析確定樣本數(shù)據(jù)的適用性,最后運用結(jié)構(gòu)方程模型進行量化分析,確定各單元與高鐵運營過程安全的相關(guān)性,將模糊問題數(shù)學(xué)化。(4)構(gòu)建了列車控制中心預(yù)警管理系統(tǒng)。針對影響最大的因子,構(gòu)建預(yù)警管理系統(tǒng),在分析安全預(yù)警基本機制的基礎(chǔ)上,從預(yù)警內(nèi)容和預(yù)警對策入手,著重討論了列車控制單元預(yù)警管理系統(tǒng)的各項監(jiān)測指標(biāo)以及對預(yù)警區(qū)間的劃分,進一步提出了高速鐵路列控單元預(yù)警管理系統(tǒng)的工作流程,同時從有效和失效的角度討論了列控單元預(yù)警管理系統(tǒng)的運作模式,為高速鐵路運營安全提供技術(shù)支持。
[Abstract]:Safety, as the main line of operation, runs through the whole process of railway transportation and is the focus of staff and the public. In recent years, with the rapid development of high-speed railway, the mileage of its operation reaches the first in the world, and the network scale is expanding day by day. However, while the world cheered for the rapid development of high-speed railway, the safety of high-speed railway operation has also been put on the agenda. Because the high-speed railway system is huge and complex, involving many departments such as car, machine, industry, electricity, vehicle and so on, the risk sources of its personnel, equipment, environment and management are also increasing day by day. In order to deal with the sudden accidents in the process of high-speed railway operation, this paper studies the identification and early warning of the safety risk factors in the operation of high-speed railway, uses the systematic method to identify the risk factors, and establishes the index system of the risk factors. The correlation analysis is carried out to determine the most influential factors and to construct an early warning management system to provide practical theoretical reference and practical significance for further ensuring the safety of high-speed railway operation process. The research work of this paper mainly includes the following aspects: 1) constructing the safety chain model of high-speed railway operation process. Based on the field investigation and analysis of Taiyuan Road Bureau, the definition and goal of high-speed railway operation safety are determined. At the same time, on the basis of analyzing the operation process of high-speed railway, it starts with three major links: line foundation, operation dispatch and operation control. The safety chain model of high-speed railway is established, and the four units (dispatching center, line foundation, train control center, train operation system) of the safety chain model of high-speed railway are analyzed in detail, and the safety chain nodes of each unit are determined. Thus, the application of safety chain model of high-speed railway is put forward. The safety risk factors of high-speed railway operation process are analyzed, and the safety risk index system is established. Based on the safety chain model and HAZOP analysis method, this paper analyzes and determines the safety risk factors of high-speed railway operation process from the four aspects of "mannequin equipment environment management". At the same time, the rough set theory is used to reduce and extract the safety risk factors. Finally, the optimization of the safety risk index body is carried out. Finally, the correlation analysis of the safety risk index system factors in the operation process of high-speed railway is carried out. According to the core index system of the security risk factor, the questionnaire is designed to obtain the sample data, and the applicability of the sample data is determined by reliability and validity analysis. Finally, the structural equation model is used for quantitative analysis. The correlation between each unit and the safety of high-speed railway operation is determined, and the fuzzy problem is mathematized to construct the early warning management system of the train control center. Based on the analysis of the basic mechanism of security early warning, the paper starts with the contents and countermeasures of early warning. The monitoring indexes of train control unit early warning management system and the division of early warning interval are discussed, and the workflow of train control unit early warning management system of high speed railway is put forward. At the same time, the operation mode of train control unit early warning management system is discussed from the point of view of efficiency and failure, which provides technical support for high-speed railway operation safety.
