自动控制文献翻译——信号综合系统是以车站信号计算机局域网为基础，以专用通道构成的计算机广域网为骨架，以综合调度中心局域网为龙头构成的铁路信号综合控制系统。可细分为4个子系统，分别为车站联锁、列车运行控制、列车运行指挥、车站联锁、和信号集中监测。

列车运行指挥子系统(CTC)的系统设备及功能：

1.1 系统设备

1.1.1 调度中心设备

系统采用标准的快速交换以太网，由网络交换机连接系统中所有的通信服务器、应用服务器、工作站、计算机、路由器、远程拨号访问服务器及具有网络接口的外部设备。系统设备均为主、备方式连接。调度中心由实时局域网络交换机、应用服务器、通信服务器、运行图、扫描仪以及传输介质等主要硬件冗余配置。调度员等用户工作站与交换机通过双以太网进行信息交换。

1.1.2 车站终端设备

车站终端设备由车站CTC分机、车站行车信息台、本地控制台和车次号输入设备组成。

(1)CTC分机设于车站机房，对应每个计算机联锁车站设1套(双机热备)，与车站联锁列控设备接口，以完成对车站的本地控制、调度中心控制时的链路通信任务、接受调度中心计算机下达的车站3h接发车计划，并按计划实施自动控制列车进路或按调度中心进路命令控制列车进路。

(2)行车信息台显示本站列车运行的阶段计划和相邻车站的重叠信息，设于车站控制室。

(3)根据运输部门的使用要求，暂设置车站本地控制台，具有车站站场、操作按钮显示等功能。通过与CTC分机接口可办理与调度中心控制权的交换手续，实施站控办理进路、区间封锁等作业。.......

Signal integrated system is based on the station signals computer LAN, using a dedicated channel for net lines for the integrated control center LAN to lead a comprehensive railway signal control system .could be broken down into four sub system respectively train operation control, operational command ，station chain, and monitoring signals on the train. 

the equipment and functions of the trains command subsystem (CTC)：

1.1 system equipment

1.1.1 dispatch center equipment

Rapid exchange system using standard Ethernet from the network switching systems connecting all communications servers, application servers, workstations, computers, routers, remote access server and dial-up network interface with external equipment. System equipment are based, a way to connect. Real-time local area network switches from activation center, application servers, communications servers and operating plans, scanners and transmission medium, and other major hardware redundancy configuration. Controllers, and other user workstations with dual Ethernet switches through information exchange.

1.1.2 railway station terminals

Station by station CTC ext terminals, traffic information station table, local control of the importation of equipment and trips.

(1) CTC ext stations located in room, a computer chain stations located one each corresponding sets (two aircraft heat up), is charged with station chain equipment interfaces to complete local control of stations. Dispatch center, control communications links task, Accept the dispatch center, computer stations 3h then went down plan with the implementation of automatic control plan into train or dispatch center at the train into control orders into train.

(2) Travel information table shows ever train operation phase and adjacent stations overlap information at the station control room.

(3) According to the transport sector use, temporarily set up local control stations, a table have station site、 Button shows, and other functions .With CTC ext interface can handle dispatch center with the exchange control procedures for the implementation of station control approaches, Interval blockade, and other operations.

(4) CTC station terminals for visitors guides station equipment interfaces.

(5) CTC ext chain is charged with equipment，redundant contact interfaces is used in the local communications interfaces......
