论城轨ATP系统工作原理及安全措施毕业论文摘要:城市轨道交通列车自动超速防护系统ATP自身的作用是保证轨道交通的行车安全，安全可靠性要求极高，其自身的安全可靠性受到了诸多关注。本学位论文首先从城市轨道交通列车超速防护系统ATP的结构、类型和基本工作原理的分析入手，重点对车载ATP系统的可靠性进行了较为深入的研究。论文结合了南京地铁一号线实际运行的ATP系统，简要介绍了这类ATP系统的结构和工作原理。对于车载ATP系统，为了能够深入研究其系统可靠性，计算ATP子单元的双机并行暂态和稳态有效度值，以及整个ATP系统的稳态有效度。经过实例计算，证明ATP系统的有效度高，能够满足安全行车的需求。本文还提出和分析影响车辆安全运行的具体因素，针对这些具体因素，使用两两比较法，将这些因素对于安全行车影响能力进行排序，并提出相对应的改善策略。最后，根据灾变灰预测理论，预测出同类硬件群体失效率异常的时间段，以便于对ATP系统提出合理安排检修的日期。关键词:工作原理;列车超速防护;安检AbstractUrbanTransitSystemAutomationTrainProtectionasanimportantfactortoprotecttrainsafety.ThereliabilityofAutomationTrainProtectionisaskedveryhigh,whichtobepaymuchattention.Thistheismstartatthestructure,typeandworkprincipleofUrbanTransitAutomationTrainProtection,andgiveemphasizetostudythereliabilityofon-boardATP.IntroducestructureandworkprincipleoftheATP,whichareactinginthenumberonelineofShenzhenunderground.Forstudyingthereliabilityofon-boardATPfarther,CalculatethevalueofInstantaneousAvailabilityandSteadyAvailabilityofATP'unitwhichacttheendwithtwosameequipment.AndcalculatetheSteadyAvailabilityofthewholeATP.Aftertheexamplecalculation,provethatthereliabilityoftheATPisveryhigh,whichcansatisfyrequireoftrainsafety.Thetheismputforwardandanalyzesomefactorswhichinfluencetrainsafety,tomakesurethatthesefactors'influenceabilityfortrainsafety,thethesisusetwo-twocomparewaytogetit.Thenputforwardcorrespondingsettleway.Finally,inordertoarrangerationaltimeforexamineandrepair,accordingasCalamitiesGreyPrediction,predictiontheperiodoftimeofFailureRateabnormity.Keywords:TheWorkingPrinciple;AutomationTrainProtection;SecurityCheck.目录第1章绪论.................................................................................................................31.1课题背景....................................................................................................31.2国内外现状..................................................................................................41.3课题研究的实际意义.................................................................................41.4论文的结构..................................................................................................5第2章ATP系统构成和工作原理...........................................................................52.IATP系统的功能...........................................................................................52.2ATP系统的结构、分类和工作原理...........................................................62.2.1ATP系统的结构...............................................................................62.2.2ATP系统工作的分类.......................................................................72.2.3点式ATP的工作原理......................................................................82.2.4采用轨间电缆的连续式ATP的工作原理......................................92.2.5采用轨道电路的连续式ATP的工作原理......................................92.3三种方式的ATP优缺点比较....................................................................102.3.1点式ATP的优缺点......................................................................…102.3.2采用轨间电缆连续式ATP的优缺点.............................................112.3.3采用轨道电路连续式ATP的优缺点..............................................11第3章列车超速防护.......................................................................................……123.1轨道交通ATP的“故障—安全”准则................................................……133.2列车检测..................................................................................................143.3列车自动限速..............................................,...........................................153.4目标速度和目标距离..............................................................................163.5制动模式..................................................................................................173.6测速与测距..............................................................................................183.7速度限制..................................................................................................193.8常用制动和紧急制动..............................................................................15第4章加强ATP系统安全性的方法......................................................................394.1造成不安全行车的因素..........................................................................394.2加强设备故障预测...................................................................................394.3提高工作人员的管理和作业能力...........................................................494.3.1提高驾驶人员和控制中心人员的工作能力................................494.3.2提高检修人员的作业能力............................................................494.4提高轨道交通运输公司的质量管理能力...............................................494.4.1建立安全质量小组........................................................................504.4.2建立轨道交通设备质量跟踪制度................................................504.4.3建立应急小组................................................................................504.5增强应对环境的影响能力.....................................................................51结论..........................................................................................................................11致谢.........................
