目前中国列车控制系统 -3 ( Chinese Train Control System 3 ; 简称为 CTCS-3 ) 是基于铁路全球移动通信系统 ( Global System for Mobile Communications For Railway; 简称为 GSM-R ) 的无线通信实现车-地信息双 向传输。
但是 ETCS和 ITCS中的 RBC都不符合 CTCS级列车的标准, 无法应 用到 CTCS-3级列车中, 因此, 亟待需要提出一种能够应用于 CTCS-3级 的 RBC。

为使本发明实施例的目的、 技术方案和优点更加清楚, 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一部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有作出创造性劳动前提 下所获得的所有其他实施例, 都属于本发明保护的范围。
图 1 为本发明实施例提供的一种 CTCS-3级的 RBC设备的结构示意 图。 如图 1所示, 本实施例的 RBC设备具体可以包括: 主机 10和综合业 务数字网 (Integrated Services Digital Network; 以下简称 ISDN )服务器 11。
本实施例的 CTCS-3级的 RBC设备中的 ISDN网服务器 11用于接收 列车发送的包括有列车位置的列车参数信息, 如接收来自列车的位置报告 和列车数据。 ISDN服务器 11还与主机 10连接, ISDN服务器 11用于将 接收到的列车参数信息发送给主机 10。 主机 10还用于接收至少一个计算 机联锁 ( Computer Based Interlocking; 以下简称 CBI ) 上报的轨道状态信 息, 并根据接收到的列车参数信息、 轨道状态信息和预配置的线路配置数 据为列车配置移动授权 ( Movement Authorization; 以下简称 MA )许可; 主机 10还用于将 MA许可通过 ISDN服务器 11发送给列车, 以控制列车 的行使。
需要说明的是,本实施例的 CTCS-3级的 RBC设备中的 ISDN服务器
11 通过基于铁路全球移动通信系统 ( Global System for Mobile Communications For Railway; 以下简称 GSM-R ) 网络与列车实现通信。 即该 ISDN服务器 11是主机 10和 GSM-R之间的接口, ISDN服务器 11 和主机 10之间通过以太网连接, ISDN服务器 11和 GSM-R网络釆用基本 多路连接( S2M ) 。 ISDN服务器 11集成了 ISDN 接口卡 (支持 ISDN通 信协议, 例如 ISDN基本速率接口 ( Primary Rate Interface; 以下简称 PRI ) 卡) 。 其硬件平台可以釆用安装 LINUX操作系统的商业通用服务器, 其 功能实现也能符合欧洲无线协议非安全层。 ISDN服务器 11的硬件平台也 可以是基于 Windows NT操作系统的标准工控机, 用以执行欧洲无线标准 的非安全层协议功能。
本实施例的 CTCS-3级的 RBC设备中的 ISDN服务器 11可以同时与 30个列车相通信, 同时处理 30辆列车的信息。 而且本实施例的 RBC设备 中一个主机 10最多可以连接 4个 ISDN服务器 11。 主机 10和 ISDN服务 器 11之间通过外部交换机连接。
本实施例的主机 10可以釆用基于二乘二取二的现货供应的通用服务 器的安全计算机平台实现。 即主机 10 同一时刻有两套完全相同的设备在 工作, 两套设备互为备用, 每一套设备可以称为一个无线闭塞单元(Radio Block Unit, 以下简称为 RBU ) , 本实施例中可以认为每一套设备中包括 RBU1和 RBU2。 例如可以认为 RBU1为主设备, RBU2为备用设备。
图 2所示为本发明实施例提供的一套 RBU的功能结构图。 如图 2所 示, 自底向上可分为六层, 1一 3层为安全平台部分, 提供了整个安全平台 的硬件、 操作系统以及 API接口部分, 这一部分可以用于任何可以釆用二 乘二取二安全平台的应用; 第 4层是应用程序的框架, 提供了一个在安全 平台上编写应用程序的 framework, 根据需要开发不同的安全设备有可能 使用相同或不同的框架; 第 5、 6层则属于 RBC专用的无线闭塞逻辑处理 应用软件部分。
如图 3所示为本发明实施例提供的 CTCS-3级的 RBC设备的主机的结 构图。 如图 3所示, RBC设备的主机由两套 RBU组成, 每一套 RBU中包 括有 A、 B 和 C 三个功能单元构成, 其中 A、 B 为故障-安全处理单元 ( Fail- Safe Processing Unit ; 以下简称 FSPU ) , C为服务处理单元( Service Processing Unit ; 以下简称 SPU )。每个单元包括计算机平台和软件应用。 由于计算机平台的 CPU本身并不具有安全性, 需要通过单元 A和单元 B 的处理过程来保证安全性。 RBC的主要功能分为安全任务处理(无线闭塞 逻辑处理应用软件)和非安全任务处理(服务应用软件) , 安全任务处理 由故障-安全处理单元( 和8 ) 实现, 非安全任务处理由服务处理单元 C 实现。应用软件通过应用程序编程接口(Application Programming Interface; 以下简称 API)与操作系统、 系统硬件接口。
主机 10中的两套 RBU可以分别釆用如下三种工作状态: 工作模式、 热备模式和冷备模式进行工作。
两套 RBU可以釆取如下的模式组合进行工作: 工作模式与热备模式、 工作模式与冷备模式。
正常工作时, 两套 RBU按照工作模式与热备模式的组合进行工作: 正常启动后,有一套 RBU工作在工作模式,另一套 RBU工作在热备模式。 处于工作模式的 RBU 负责一切逻辑运算处理, 以及与外部信息的交互, 处于热备模式的 RBU不做逻辑处理与运算, 不与外界进行信息交互, 只 接受工作模式的 RBU所发送的数据以确保内部状态与对方相同, 当工作 模式的 RBU发生故障时, 该 RBU将导向安全侧, 热备模式的 RBU能在 规定时间内完成从待机到在线状态的切换, 进入工作模式。 该时间值从工 作模式的 RBU检测到一个故障情况并决定停机开始, 到热备模式的 RBU 检测到该状态变化为止。 导向安全侧后的原工作模式 RBU将重新启动, 与当前处于工作模式的 RBU建立通信会晤后, 进入热备模式继续运行。 此外也可以通过人工命令进行双系切换, 即把热备模式的 RBU切换为工 作模式, 工作模式的 RBU切换为热备模式。
对于两套 RBU按照工作模式与冷备模式的组合进行工作时: 此时两 套 RBU中处于工作模式的 RBU正常工作, 另一 RBU没有收到处于工作 模式的 RBU所发送的即时数据, 即处于冷备模式, 例如该 RBU未上电启 动时。 一旦工作状态的 RBU 出现故障, 整个系统直接导向安全侧, 没有 正处于热备模式的 RBU可以立即切换为工作模式继续工作, 降低了设备 的可用性。 在此模式下, 需要维护人员进行确认, 才能监控列车的运行, 从而确保系统安全性和可用性。
每一个 RBU中的三个功能单元 A、 B和 C釆用现货供应的通用服务 器, 便于部件釆购, 又可以及时的进行升级换代, 以提供更好的性能。 两 个独立的故障-安全处理单元( FSPU ) A和 B, 要求釆用不同的 CPU和操 作系统 (其中 CPU字节序应为一个大端、 一个小端, 操作系统要求均符 合 POSIX标准,在本 RBC系统中, A釆用 Intel的 i386的 CPU和 Freebsd 操作系统, B釆用 PowerPC的 CPU和 Linux操作系统 ) ; 软件方面两个 FSPU实现相同的任务, 以构成 2取 2结构, 即所有输入、 输出以及运算 结果等都要经过交叉比较确认一致才认为正确。 为满足安全完善度(SIL ) 4级, 交叉比较中的任何偏差、 程序溢出、 存储和时钟校核不正确都会引 起 FSPU导向安全, 并同时切换至备用的 RBU。
服务处理单元实现对其他外部单元或设备和系统的输入 /输出等服务 功能, 将从调度集中 ( Centralized Traffic Control; 以下简称 CTC )、 CBL 临时限速服务器 (Temporary Speed Restriction Server, 以下简称 TSRS ) 等外接设备接收的信息进行解析分配发送给两个 FSPU, 并将从 FSPU接 收到的信息发送给外部单元或设备。 当在线 RBC 系统故障时负责完成至 备用 RBC的切换, 以及对外发送报警、 记录和存储日志等。
RBU 内部各机以及两套 RBU之间的信息交互通过两台内部交换机 ( DSW1和 DSW2 ) 进行, RBU与外部的信息交互 (如与 ISDN服务器、 监测机、 CBI等) 则通过两台外部交换机 ( ESW1和 ESW2 ) 完成, 通过 对外部交换机划分 VLAN从而使 RBC通过不同的网段与外部交互信息, 从而达到信息的隔离。
RBU的应用逻辑处理软件部分, 分为 3个层次: 即一般产品、 一般应 用和特定应用。
故障-安全应用软件就是一般产品, 实现基于 CTCS-3级规范的列车监 控规则。 包括无线闭塞逻辑核心软件, 以及与适配软件部分的通用接口。 无线闭塞逻辑负责监督列车状态, 并基于列车报告的状态, 来自 CBI的进 路信息, 静态线路基础数据和临时限速来确定列车的移动授权(或紧急消 息) 。 这一部分核心逻辑对所有 CTCS-3级的线路保持完整。
故障-安全适配软件是指一般应用, 包含特定用户的操作规则, 以及与 外部设备的接口适配, 例如与 CBI、 TSRS和其他可用的外部系统的接口 适配。 这是由于, 在不同的线路上, RBC所连的外接设备可能是不同厂家 生产的各种不同型号的产品, 或是具体的运营规则有变化, 因此需要对其 进行适配。
适配数据是指一般应用使用的配置数据 (例如: IP地址, 接口超时, 对象传输数据) , 适配数据是一般应用的一部分。
工程配置数据是指一般产品使用的站场数据(例如: 基础构造数据和 其他应用的特性数据) , 它属于特定应用。
这种三层设计, 可以比较容易的实现应用数据修改, 例如站场布局改 变, 只需改变工程配置数据; 若特定线路运营规则变化或釆用了不同型号 的设备, 只需修改适配部分软件, 而核心的系统软件和所有的硬件保持不 变。
本实施例的 RBC设备,通过釆用 ISDN服务器用于接收列车发送的包 括有列车位置的列车参数信息; ISDN服务器还与主机连接, 用于将接收 到的所述列车参数信息发送给主机;主机还用于接收至少一个 CBI上报的 轨道状态信息, 并根据列车参数信息、 轨道状态信息和预配置的线路配置 数据为列车配置 MA许可; 主机还用于将 MA许可通过 ISDN服务器发送 给列车, 以控制列车的行使。 釆用本实施例的技术方案, 能够为现有技术 的 CTCS-3级列车提供一种 RBC设备,从而提高 CTCS-3级列车的运营效 率。
图 4为本发明实施例提供的另一种 CTCS-3级的 RBC设备的结构示意 图,如图 4所示, 本实施例的 CTCS-3级的 RBC设备在上述实施例一的基 础上, 还可以进一步包括监测机 12。
监测机 12的硬件和操作系统应与上述实施例中的主机 10中的工作状 态的设备即工作状态的 RBU中的 C单元硬件和操作系统类型相同, 并与 主机 10安装在同一个机架上。 监测机 12有四个网络接口, 均与外部交换 机相连。 其中两个通过端口镜像技术与主机 10连接, 用于检测主机 10与 外接设备之间的连接状态以及主机内部两个 RBU之间的连接状态, 如检 测主机 10中工作状态的 RBU与外接设备之间的信息交互, 并分析得出工 作状态的 RBU和外接设备之间的工作状态以及通信连接状态。 这里的外 接设备可以为 CBI、 TSRS和相邻的 RBC设备。 监测机 12还用于检测工 作状态的 RBU与 ISDN服务器 11之间的工作状态以及通信连接状态。

本实施例的 CTCS-3级的 RBC设备还可以包括接口服务器 13。 该接 口服务器 13分别与主机 10和 CTC连接,用于将主机的状态报告给 CTC, 并接收 CTC所发出的命令或消息转发给相应的 RBC设备的主机。 还包括 维护终端 14, 该维护终端 14分别与接口服务器 13和监测机 12连接, 用 于显示接口服务器 13和监测机 12的状态。 具体地, 该维护终端 14与监 测机 12、 接口服务器 13相连并获取它们所发送的内部状态以及通信连接 状态等信息, 以图形、 声音等方式显示于人机交互界面, 并接受维护人员 下达的命令, 从而实现对 RBC设备的维护与操作。 这样, 监测机 12的另 外两个端口与维护终端 14相连接, 将检测到的工作状态的 RBU和外接设 备之间的工作状态以及通信连接状态、 以及检测到的工作状态的 RBU与 ISDN服务器 11之间的工作状态以及通信连接状态等监测信息发送给维护 终端 14, 以供维护终端 14显示。
本实施例的 CTCS-3级的 RBC设备中还可以包括司法记录器 ( RBC-
Juridical Recording Unit; 以下简称 R-JRU ) 15。 该司法记录器 15和主机 10连接, 该司法记录器 15用于记录主机 10中的信息。 具体地用于获取并 记录 RBC设备中的主机 10中的各种逻辑处理、运算、控制、接口等信息, 存储于其上, 其记录可作为司法依据。
本实施例中, 接口服务器 13 可以由两台现货供应的完全相同的通用 服务器及相应的软件构成, 与司法记录器 15 安装在同一个机拒。 单独一 台通用服务器即可实现接口服务器的功能, 两台服务器互为备用, 实现冗 余配置。 接口服务器 13 实现主机 10与 CTC之间的信息交互功能。 需要 说明的是, 一个接口服务器 13最多可以同时与 9个 RBC设备的主机相连 接, 并与对应的一套维护终端 14连接。
接口服务器 13实现的接口功能可以包括如下接口:
( 1 ) 主机 10和接口服务器 13的接口;
( 2 ) 接口服务器 13和 CTC的接口;
( 3 ) 接口服务器 13和维护终端 14的接口;
( 4 ) 接口服务器 13和司法记录器 15的接口。
当同一个接口服务器 13连接有多个 RBC设备的主机 10时, CTC通 过接口服务器 13向 RBC设备的主机 10发送消息, 接口服务器 13能判断 将该消息传送至哪个 RBC设备的主机 10。 RBC设备的主机 10也可以把 其当前工作状态、 列车运行状态以及各种警告消息通过接口服务器 13 向 CTC发送。 接口服务器 13记录 RBC设备的主机 10和其自身的报警和事 件信息, 每则信息均保存相应的时间戳, 以备检查。
本实施例中的维护终端 14允许维护人员使用 RBC中的维护、 诊断等 功能。 需要说明的是, 一个维护终端 14可以最多与 15个 RBC设备的监 测机 12相连接, 与之连接的 RBC设备的主机 10的工作状态、 RBC设备 的主机 10与其它外接设备的通信状态以及与 RBC设备的主机 10的相关 的警告将在该维护终端 14上显示。 此外, 所有与之连接的 RBC设备的控 制范围内的站场运行图以及列车运行状况也都显示于终端图形界面上。
本实施例中的维护终端 14 可以记录所接收的事件和信息, 并可以根 据记录进行运营场景回放。 此回放功能可支持有关人员查阅记录事件(回 放功能只能在离线环境下使用) , 此外, 还能在特定事件或不同的时间点 上开始播放和停止,并可以暂停。维护终端 14还可以在报警窗口显示 RBC 设备的所有事件通知和报警。 报警根据不同类型进行区分, 如信息源、 报 警代码、 报警等级等等。 当 RBC设备发生重启或某通信连接断开等严重 故障时, 维护终端 14将发出声音报警提醒维护人员。
需要说明的是, 实际应用中, 司法记录器 15与接口服务器 13位于同 一机拒, 由一台现货供应的通用服务器及相应的软件构成。 司法记录器 15 与 RBC设备的主机 10相连接, 由 RBC设备的主机 10将各种控制、 接口 等信息推送给司法记录器 15 进行记录, 其记录可作为司法依据。 信息和 事件的记录功能基于计算机硬件平台和以太网数据通信来实现。 司法记录 器 15记录的用于系统事故后的故障调查。 而且司法记录器 15还提供工具 以支持对日志的分析, 可以在 CD/DVD上对日志进行存档。
需要说明的是,上述实施例的 CTCS-3级的 RBC设备中还可以包括密 钥管理工具 16和工程配置工具 17。 该密钥管理工具 16与主机 10连接, 但是该密钥管理工具 16为离线工具, 用于分别为主机 10提供与列车、 外 接的地面安全设备(包括 CBI、 TSRS、 相邻 RBC )之间通讯的通讯密钥。 由于列车与主机 10之间的通讯、 外部设备与主机 10之间的通讯, 在一段 时间内通讯双方都需要按照通信密钥进行通信。 该密钥管理工具 16就是 用于向主机 10提供通信的各种密钥, 以确保该主机 10与列车、 外接设备 之间的通讯。 该密钥管理工具 16可以看作是釆用软件制作的工具, 能够 提供在一段时间内有效地动态密钥。 需要说明的是, 在列车、 外接设备也 分别设置有对应的密钥管理工具, 用于提供与 RBC设备中的主机 10中获 取的密钥对应的密钥。 工程配置工具 17用于为主机 10提供预配置的线路 配置数据; 工程配置工具 17还用于向主机 10提供主机 10的 ip地址和通 信的端口。 该工程配置工具 17是根据列车行驶的轨道位置处的地形地貌 等信息配置的一些线路配置数据。 如图 5所示为本发明实施例提供的一种 RBC设备的使用状态结构图。 如图 5所示, 显示有该 RBC设备与外接设 备的连接关系。 图 6为图 5所示的 RBC设备的实例图。

需要说明的是, 上述实施例的 RBC设备的通信方式分为内部通信方 式和外部通信方式。
为保证内外部通信不互相干扰, RB C主机内部的通信均通过两个内部 交换机 DSW1和 DSW2进行, 可以参考上述图 6。 内部通信包括双系数据 传输通信: Al-A2、 Bl-B2、 C1-C2; 双机比较通道: A1-B1、 A2-B2; 故 障-安全处理单元与服务单元之间的通信通道: A1-C1、 B1-C1、 A2-C2、 B2-C2。 通信釆用 TCP/IP协议, 通过增加 CRC64校险以确保数据的正确 传递。
RBC主机与接口服务器、 ISDN服务器、 CBI、 TSRS、 相邻 RBC之间 的通信, 均由 C机通过外部交换机 ESW1和 ESW2完成。 为了保证通信的 安全, 通过将外部交换机设置 VLAN, 为与不同外设的连接配置不同网段 地址, 实现通信隔离。
本实施例的 CTCS-3级的 RBC设备通过安全接口或非安全接口与外部 系统交换信息, 安全接口的信息编码和传输设计完全符合 RSSP-2安全通 信协议。
RBC 设备实现的安全接口包括 RBC-CBI 接口, RBC-RBC 接口,
RBC-TSRS接口。 与 CBI、 TSRS、 相邻 RBC之间的通信均通过外部交换 机连接至信号安全数据网 (客运专线信号系统安全数据网) 实现, 并釆用 双系双通道的符合 RSSP-Π安全通信协议冗余通信技术,即 RBC与一外接 设备之间共有 8条通信通道, 逻辑示意图如下所示, 其中双系分别用左系 ( L )和右系 (R )表示。 如图 7所示为本发明实施例提供的双系双通道通 信逻辑示意图。
以与 CBI的通信为例, RBC设备的通信连接方式如图 8所示。
RBC设备与 ISDN服务器之间的通信通过外部交换机实现, 釆用双通 道安全冗余通信技术, 釆用内部安全通信协议。 主机与 ISDN服务器的接 口逻辑示意图如图 9所示。 RBC设备与接口服务器的通信釆用封闭的冗余 以太网, 使用基于 TCP/IP协议的双系双通道冗余通信技术, 由于并非安 全接口, 所以不使用安全通信协议, 为确保通信内容的正确, 在消息中增 加 CRC32校验。 其接口逻辑示意图与图 7同。
RBC设备与 R-JRU之间的通信釆用基于 TCP/IP双通道冗余通信技 术, 并增加 CRC32校验。 其接口逻辑示意图与图 7类似。
RBC设备与列车的车载设备的通信, 是通过 ISDN服务器与 GSM-R 网络相连, 从而实现与车载设备的无线通信, 为了确保通信的安全, 釆用 了无线安全通信协议。
