Description

一种TACS系统的列车筛选方法、系统、设备及存储介质 技术领域
本发明涉及列车信号控制系统，尤其是涉及一种TACS系统的列车筛选方法、系统、设备及存储介质。
背景技术
与传统CBTC系统相比，基于车车通信的列车自主运行系统(TACS系统)以“列车为核心”，由列车自主计算移动授权，TACS系统的本质是将传统CBTC系统的轨旁核心控制功能移植至列车上，优化系统架构，同时减少了轨旁设备数量，使设备维护工作量明显减少。
然而，由于TACS系统并没有使用传统的次级检测设备来作为列车占用检测，TACS系统缺少有效的方式来安全可靠地获知线路区段上列车的占用情况，因此在TACS系统中，如何对线路上的列车进行筛选是一个巨大的挑战。
在传统CBTC系统中，降级列车或非通信列车的筛选很大程度上依赖于轨道占用的检测，主要的轨道占用检测手段包括轨道电路和基于电磁感应技术的计轴，但这类次级检测设备的安装工艺复杂，需要布置大量的线缆，建设成本和维护成本高，此外次级检测设备存在由于自身故障而导致无法完成正确筛选的问题；
经过检索中国专利公开号CN114454923A公开了一种基于自主运行控制模式的列车筛选方法及系统，方法包括以下步骤：当前列车车载设备从道岔控制器获得计轴状态信息；当前列车车载设备从其他列车车载设备和道岔控制器，获得其他列车的位置信息；当前列车车载设备结合计轴状态信息和其他列车的位置信息完成对当前列车的筛选。针对目前城市轨道交通列车筛选判断功能涉及设备环节多且信息传递判断速度慢，导致列车完成筛选后用于移动闭塞追踪的效率降低的问题，通过对功能进行重新分配，实现多种机制的组合，降低通信传输，提高车载设备自主判断控制能力，同时还能用于列车自主运行控制模式。但是现有专利仍依赖于计轴设备来进行列车筛选，因此在TACS系统，如何设计出一种不依赖于传统次级检测设 备的列车筛选技术，成为需要解决的技术问题。

与现有技术相比，本发明具有以下优点：
1)本发明在不需要布置计轴或轨道电路等次级检测设备的情况下，通过通信列车自动筛选及人工确认的方式来完成全线区段的筛选，摆脱了对传统次级检测设备的依赖，大大减少了系统轨旁设备的数量、建设成本及维护工作量，缩短了旧线改造和新线建设的周期，提高了系统的竞争力和灵活性。
2)本发明包括自动列车筛选和人工筛选两种方式，对于正线通过通信列车来进行快速地的自动筛选，对于复杂的渡线、存车线或车辆段等特殊区段，可以使用 本地操作员按钮确认+中心调度授权的方式来进行快速的列车筛选，通过2种方式的互补，能够方便地完成线路所有区段的列车筛选功能，保证了TACS系统的列车筛选的手段多样性及易操作性；
3)本发明设计了一套列车非法入侵检测系统，保证在WRC正常工作时，如果有列车非法闯入信号区，能被系统检测出来，从而获知线路当前是否有未知列车闯入；当确认线路上没有非法列车闯入时，则列车重启或线路区段封锁取消时，当列车恢复定位后，系统能根据所有线路上的列车的位置信息来自动完成列车筛选，无须进行人工筛选操作，保证了TACS系统的列车筛选效率，使TACS系统具备了快速的故障恢复能力。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
TACS系统通过自动列车筛选和人工列车筛选的方式来实现线路区段列车占用状态的确认。当WRC上电成功后，通过WRC初始化命令对WRC进行上电解锁，保证WRC能正常工作，能执行正常的入侵检测，在线路区段筛选期间监控列车非法闯入信号区的情况；然后根据WRC提供的线路区段占用状态，来决定是否 进行列车自动筛选操作，当自动筛选操作完成后，如果在某些特殊区段，仍有未知列车占用区段存在，则需要执行人工筛选操作，实现全部线路区段列车筛选的处理。
如图2所示，本发明具体包括以下步骤：
步骤S101，轨旁资源管理器WRC上电或重启完成后，通过WRC初始化命令对WRC进行上电解锁；
步骤S102，WRC判断全线线路区段的列车占用状态，若线路区段不存在未知列车占用状态，则认为线路筛选成功，否则执行步骤S103；
步骤S103，进行自动列车筛选，并执行步骤S104；
步骤S104，当完成了线路的自动列车筛选后，判断是否还存在未知列车占用区段，若为是，执行步骤S105；否则，认为线路筛选成功；
步骤S105，进行人工列车筛选。
如图3-1所示，对于车挡连接的轨道区段，可以配置为自动筛选区，当通信列车T1的最小车头距离车挡的距离L小于线路最小车长时，则该轨道区段可以被自动筛选掉；如图3-2所示，对于信号边界处，如果布置了列车非法入侵检测设备时，则当道岔反位轨道区段小于线路最小车长时，则该区段可配置为自动筛选区，当通信列车T1从道岔P1定位通过后，则道岔P1反位的轨道区段可被自动筛选掉；如图3-3所示，当单渡线的长度小于线路最小车长+侧冲区长度时，则该渡线轨道区段可配置为自动筛选区，当通信列车T1从道岔P3定位通过后，且列车T2从道岔P5定位通过后，则渡线轨道区段可被自动筛选掉。
如图4所示，对于渡线的长度不符合配置为自动筛选区的要求时，则为了快速地进行线路区段的列车筛选，可以将该道岔区段配置为人工筛选区，由人工来确认该区段内是否有未知列车存在。
TACS系统列车人工筛选接口信息示意图如图5所示，主要涉及到轨旁资源管理器WRC、列车控制器xTC、目标控制器OC、列车自动监控系统ATS、智能运维系统IOM、列车入侵检测系统TID、筛选按钮CZB等子系统之间的接口；当系统上电成功后，ATS根据列车筛选的需要，向列车控制器xTC发送线路筛选的运行任务；列车控制器xTC向轨旁资源管理器WRC申请资源；WRC向ATS传输线路区段占用显示，ATS向WRC发送调度的人工筛选命令；本地操作人员通过筛选按钮CZB来确认区段是否在未知列车存在，并发送给目标控制器OC；OC将按钮信息发送给WRC；列车入侵检测系统检测是否有列车非法入侵到信号区内；智能 运维系统IOM能显示TACS设备的工作状态；通过各子系统之间的信息交互，TACS系统能实现列车的筛选处理；
TACS系统的列车筛选接口信息如表1所示：
表1
TACS系统的列车自动筛选工作流程如图6-1所示，自动筛选工作流程如下：
步骤S1031，WRC计算线路存在未知列车占用，并向ATS提供未知列车占用信息；
步骤S1032，ATS向调度终端显示未知列车占用线路区段信息；
步骤S1033，调度终端根据显示的占用信息，决定向列车控制器xTC发送列车筛选的运行任务；
步骤S1034，ATS向xTC发送筛选的运行任务；
步骤S1035，xTC根据收到的任务申请线路资源；
步骤S1036，WRC向xTC分配线路资源；
步骤S1037，xTC计算移动授权运行路径，并发送给ATS；
步骤S1038，ATS显示运行路径资源信息给调度终端；
步骤S1039，调度终端根据列车申请到的资源，授权司机人工驾驶列车，进行线路区段筛选；
步骤S10310，司机根据调度指令人工驾驶列车；
步骤S10311，xTC根据自身的位置，实时向WRC提供位置信息；
步骤S10312，WRC根据xTC提供的位置信息，对线路区段进行筛选，列车 物理位置通过的区段或自动筛选区自动筛选条件满足时，则认为相应区段不存在未知列车占用；
步骤S10313，ATS根据筛选的结果，确认线路区段是否完成筛选处理。
TACS系统的列车自动筛选工作流程如图6-2所示，人工筛选工作流程如下：
步骤S1051，WRC计算线路存在未知列车占用，并向ATS提供未知列车占用信息；
步骤S1052，ATS向调度终端显示未知列车占用线路区段信息；
步骤S1053，调度终端根据显示的占用信息，授权并通知本地操作员人工确认线路区段内是否存在未知列车；
步骤S1054，本地操作员确认人工筛选区内无未知列车占用且无未知列车进入时，按压轨旁确认按钮；
步骤S1055，OC采集到筛选按钮信息，并发送给WRC；
步骤S1056，WRC采集到人工筛选按钮后，向ATS发送提供人工筛选区确认信息；
步骤S1057，ATS在界面上提示调度终端进行人工筛选确认；
