城市轨道交通基于通信的列车控制系统实现互联互通存在的主要问题分析

城市轨道交通基于通信的列车控制系统互联互通对于资源共享、资金节约有着重大意义,对提高运营效率、节省投资、便于维护等都是有利的。但信号系统互联互通是一项系统工程,牵涉到多个专业,标准的制定和执行还需要经过进一步的充分讨论和研究。提出了信号系统实现互联互通存在的主要问题是列车自动调整、电子地图及物理对象编码、通信协议和安全认证等,对其中为了实现互联互通而牺牲掉的某些性能或功能,尤其是对信号系统引导未来发展的问题,都需要进行认真识别和讨论。

Analysis of Major Problems in Achieving Interoperability Standards

Interoperability has great significance for resource sharing and cost saving,it will improve the operational effi-ciency,save investment and facilitate maintenance. However, interoperability is a system engineering, involving a number of professional standards and the implementation of which needs more discussion and research works. The problems in imple-mentation of interoperability include automatic train adjust-ment,electronic map and physical object encoding, communi-cation protocol and security authentication,etc. It is necessary to identify the functions that might be sacrificed in the imple-mentation of interoperability and to discuss the future develop-ment guided by the signal system.
