自动控制文献翻译——中央ATS子系统由设备、电缆、计算机、计算机外设、网络、计算机软件等构成。ATS子系统通过数据网络与其他CBTC子系统交换数据和命令。中央ATS采用Linux平台，Linux平台是成熟的基于32位英特尔构架的、强大的、可靠的系统，符合POSIX接口标准。LAN网络由冗余的10BaseT/100BaseTX以太网交换机组成。网络中每台处理器都连接到两个网络，可以访问其他所有处理器的数据。

中央ATS系统、区域控制器、数据存储单元（DSU）、远程ATS车站控制工作站和数据通信子系统（DCS）间的通信，由配置为主/备模式的两个互为冗余的以太网（LAN）完成。LAN通过远程光缆设备与每个远程节点通信。网络复用设备（包括冗余的接入交换机、骨干交换机等）安装在中央控制室、车辆段、每个远程ATS车站控制工作站和其他DCS节点位置。

1. ATS子系统功能

ATS系统用来监视和控制正线上的所有列车的运行。

ATS提供控制与监测功能来监控CBTC子系统并与包括在此提议中的外部系统接口。ATS根据通过DCS来自每辆列车的报告，监督并显示运行中的装有CBTC设备的列车的位置，并且自动调整性能等级及停站时间以贴近时间表或满足发车间隔，此外，它还人工控制操作，其中包括：设置或解除扣车、设置或解除限速、用区域控制器（ZC）来设置或解除临时区域封锁。通常ATS无需操作人员的参与而自动执行其功能。系统根据时间表添加列车，连续地监视每辆列车的运行，并且在列车按计划结束日常运营后将其从表中删除。

列车追踪（TTT）功能通过报告上来的列车位置、操作员请求及列车调整请求来完成列车的创建、删除及移动操作。它在系统中对.......

Central ATS System consists of equipment, cables, computers, peripheral computers, networks and computer software. ATS System exchanges data and commands with other CBTC subsystems over data network. Central ATS possesses Linux computer platform, which provides a robust, reliable system, is POSIX compliant, and is based on 32 bit Intel (or compatible) architecture The LAN network is composed of redundant 10BaseT/100BaseTX Ethernet switches.  Each processor on the network is connected to both networks and has access to data from all other processors. 

Communication between Central ATS system, the Zone Controllers, the Data Storage Unit (DSU), and the remote ATS Station Control Workstations and Data Communication System (DCS) locations will be accomplished by means of two Ethernet LANs configured in the normal/standby mode.  The LAN is propagated to each remote location through a remote fiber optic cabling plant and network multiplexers, including redundant AS and BS, installed at the Central Office, the Depot, and each Remote ATS Station Subsystem and DCS location.

1.ATS Subsystem Function

The ATS system is used to supervise and control all the vehicle operation on the mainline.

The ATS provides control and monitoring facilities to supervise the CBTC subsystems and to interface with external systems as included within this proposal.  The ATS monitors and displays the location of in-service CBTC equipped trains as reported from each train via the DCS, automatically adjusts performance levels and dwell times to maintain the schedule or headway, and provides for manual control of operations that includes the holding/release of one or all trains, establishment/removal of speed restrictions, and the temporary zone closures/openings using Zone Controller (ZC).

The ATS system normally performs its functions automatically, without the need for operator intervention.  The system schedules the addition of trains, per the schedule, continually monitors each train's operation, and removes trains when they are scheduled to be out of revenue service.

Train Tracking (TTT) performs train creations, deletions and movement operations by using reported train locations, operator requests, and Vehicle Regulation......
