信号厅列控展品双语讲解脚本

欢迎来到云上科学馆信号厅。列车前方有没有运行条件，收到的信息由谁处理，需要减速时又由谁介入？接下来，我们从几类设备出发，认识列车运行控制如何把这些环节连接起来。

Welcome to the Signaling Hall of the Cloud Science Museum. What operating conditions lie ahead of a train? Which equipment processes the information, and which system intervenes when protection is needed? Let us look at the equipment that connects these functions.

列车运行控制系统由车载、地面和通信设备协同工作，依据运行条件实施列车安全防护。高铁“大脑”是科普比喻，不表示全部调度、驾驶和安全功能由一台设备承担。[S01]

Train control combines onboard, trackside and communication equipment to provide protection under specified operating conditions. The “brain” is a teaching analogy, not a single device responsible for every railway function. [S01]

CTCS是中国列车运行控制系统。CTCS-2与CTCS-3的区别应从系统结构和信息传输方式理解；CTCS-3利用无线通信传输行车许可。等级不能直接等同于固定运行速度或固定追踪间隔，实际能力受线路、车辆和运营条件约束。[S01]

CTCS means Chinese Train Control System. CTCS-2 and CTCS-3 differ in architecture and information transmission; CTCS-3 uses radio to transmit movement authorities. A level alone does not determine a fixed speed or headway. Actual performance depends on the railway, rolling stock and operating conditions. [S01]

RBC（无线闭塞中心）是CTCS-3的关键地面设备，综合相关线路和列车信息生成行车许可，经无线通信传送给车载设备。它不等于整个调度系统。[S01]

The Radio Block Centre, or RBC, is a key trackside component of CTCS-3. It uses relevant track and train information to generate movement authorities and sends them to onboard equipment by radio. It is not the entire dispatching system. [S01]

应答器（balise）是轨旁信息传输设备，列车经过时向车载设备传送报文，可用于位置校正及相关线路信息传输；它并非持续追踪列车的定位设备。[S01]

A balise is a trackside information device. As a train passes, it transmits telegrams to onboard equipment for functions such as position correction and line information. It does not continuously track the train. [S01]

安全计算机平台承担安全相关计算。SIL4为安全完整性等级4，具体等级要求和认证结论必须对应标准、产品及适用范围；不能据此声称系统绝不会失效，也不能外推为所有列控装备均已取得同一认证。[S01、S11]

A safety computer platform performs safety-related computations. SIL4 means Safety Integrity Level 4. Requirements and certification claims must refer to a particular standard, product and scope; they do not mean that failure is impossible. [S01, S11]

ATP是列车自动防护，监督运行并在满足干预条件时实施防护；ATO是列车自动运行，在相应系统配置和防护约束下执行自动驾驶功能。不能把二者混同，也不能对所有线路承诺厘米级停车精度。[S01]

ATP means Automatic Train Protection: it supervises train operation and intervenes when protection conditions are met. ATO means Automatic Train Operation: it performs driving functions within the applicable system and protection constraints. Stopping accuracy depends on the installation and conditions. [S01]

2010年12月30日，北京地铁亦庄线CBTC示范工程开通运营。这里的CBTC指基于通信的列车运行控制系统，属于城市轨道交通案例，不等同于高铁CTCS-3，也不把CBTC与移动闭塞当作完全相同的概念。[S03、S04]

The Yizhuang Line CBTC demonstration project opened on 30 December 2010. CBTC stands for Communications-Based Train Control. This is an urban rail example, distinct from high-speed rail CTCS-3. CBTC and moving block should not be treated as strictly interchangeable terms. [S03, S04]

北京交通大学相关平台开展CTCS-3车载设备互联互通测试及RBC功能测试。其价值在于检验设备是否满足要求、接口是否协调以及故障场景下的响应，不能把单个平台直接表述为实现全国跨线运营的唯一原因。[S05]

Platforms at Beijing Jiaotong University support interoperability testing of CTCS-3 onboard equipment and functional testing of RBCs. Testing checks requirements, interfaces and responses under defined conditions. It does not by itself prove universal interoperability across a railway network. [S05]

2022年3月19日，匈塞铁路贝尔格莱德至诺维萨德段开通运营；这一日期仅指贝诺段。2023年10月2日雅万高铁正式启用，10月17日两国元首共同为其正式开通运营揭幕。匈塞与雅万的规范及列控方案应分别说明，不统一标为CTCS-3。[S08、S09、S10]

The Belgrade–Novi Sad section of the Hungary–Serbia railway opened on 19 March 2022. The Jakarta–Bandung high-speed railway was inaugurated on 2 October 2023; the two heads of state marked its official opening for operation on 17 October. The projects follow their respective technical requirements and must not both be labelled CTCS-3. [S08–S10]

宁滨（1959—2019）长期从事轨道交通运行控制研究，1977年考入北方交通大学，1982年留校任教，2017年当选中国工程院院士，曾任北京交通大学校长。人物贡献应结合团队协作及科研育人背景说明。[S06、S07] 本项目采用六个教学观察角度：自主创新、协同攻关、标准意识、场景验证、人才传承、开放合作。这是对材料的学习归纳，并非权威排名、量化研究结果或成功的唯一因果解释。

Ning Bin (1959–2019), a railway control researcher and former president of Beijing Jiaotong University, was elected to the Chinese Academy of Engineering in 2017. Our project uses six learning perspectives: independent innovation, collaboration, standards awareness, scenario-based validation, talent development and international cooperation. These are our teaching synthesis, not a quotation or a causal research finding. [S06, S07]
