This International Standard is applicable to safety—related electronic systems(including sub- systems and equipment)for railway signalling applications. The scope of this standard,and its relationship with other IEC standards,are shown in Figure 1. This standard is intended to apply to all safety-related railway signalling systems/sub- system/equipment.However,the hazard analysis and risk assessment processes defined in IEC 62278 and this standard are necessary for all railway signalling systems/sub— systems,equipment,in order to identify any safety requirements.If analysis reveals that no safety requirements exist(i.e.:that the situation is non-safety-related),and provided the conclusion is not revised as a consequence of later changes,this safety standard ceases to be applicable. This standard applies to the specification,design,construction,installation,acceptance, operation,maintenance and modification/extension phases of complete signalling systems,and also to individual sub-systems and equipment within the complete system.Annex C includes procedures relating to electronic hardware components. This standard applies to generic sub-systems and equipment(both application-independent and those intended for a particular class of application),and also to systems/sub- systems/equipment for specific applications. This standard is not applicable to existing systems/sub-systems,equipment(i.e.those which had already been accepted prior to lhe creation of this standard).However,as far as reasonably practicable,this standard should be applied to modifications and extensions to existing systems,sub-systems and equipment. This standard is primarily applicable to systems/sub—systems,equipment which have been specifically designed and manufactured for railway signalling applications.It should also be applied.as far as reasonably practicable,to general-purpose or industrial equipment(e.g.: power supplies,modems,etc.),which is procured for use as part of a safety—related signalling system.As a minimum,evidence shall be provided in such cases to demonstrate —either that the equipment is not relied on for safety, 一or Ihat the equipment can be relied on for those functions which relate to safety. This standard is applicable to the functional safety of railway signalling systems.It is not intended to deal with the occupational health and safety of personnel;this subject is covered by other standards.
在科技部、铁道部、中国科学院、上海市政府的支持下,双方决定共建轨道交通传感与传输联合实验室,不断努力和创新,创建世界一流的轨道交通传感与传输技术科研基地。 据中国铁路通信信号集团公司副总经理缪伟忠介绍,该实验室依托上海微系统所和中国铁路通信信号集团公司组建,初期整个建设费用达5000万左右。...
列车从亦庄站始发,途中驾驶人员仅需做一些简单操作,列车基本处于自动行驶状态;如遇前方车辆,该车可以自动检测、调整与前车的距离;列车到站停靠一步到位,而不像其他控制系统在列车停靠时要作微调才能到位。 CBTC是一种采用先进的通信、计算机技术,连续控制和监测列车运行的系统,同时也是地面控制系统和列车间的双向传输系统,区别于传统的单向传输系统,具有扩展性好、施工维护简单、传输方式优越等优势。...
光信号的相位与振幅同时多值调制的所谓QAM方式的数据,隐秘在量子噪声中,为加密的QAM型ANSC方式。另一方面,日本开发了通过接近单一光子的微弱激光,安全传送生成和解密用秘钥的4值QKD方式。 为统和这两种方式,专家们制作了每隔一秒就更新公用秘钥的安全高速、大容量的隐秘光通信系统。使用商用的光通信素子,与既有的光通信系统之间的整合性高。 ...
十年前,艾渤刚来到北京交通大学时,钟章队把“高速移动复杂场景的无线信道理论与方法研究”这个方向交到他手中。 “列车高速移动会引起信道的非平稳性”是国际国内专家都急于解决的难题,无线传播信道特性决定无线通信系统性能。对于传输列车控制信号的专用移动通信系统,其无线信道特性是专用移动通信网规划与优化、可靠传输关键技术性能评估、确保列车安全运营的重要基础,因此被列入《一万个科学难题》(轨道交通卷)。 ...
