移动通信网络架构演进规律对列车运行控制系统发展的启示

根据城镇化发展需要以及电子信息系统发展规律,列车控制系统一直在探索实践中发展。作为列车控制系统基础的移动通信网络,其内在发展规律和已有实践成果,对列车控制系统有较高借鉴参考价值。通过研究从2G到5G的移动通信网络架构演进以及关键接入设备结构功能变化,归纳总结移动通信网络演进规律,即结构扁平化、功能前置化以及平台虚拟化。运用该规律对以列控联锁一体化为代表的实践进行解释,并提出可能的发展趋势,包括感知决策执行端直通以及业务功能向车载转移。

Enlightenment of Mobile Communication Network Evolution on Train Control System Development

According to the needs of urbanization and the development of electronic information systems,train control system develops through exploration and practice.As the basis of train control system,mobile communication network has a high reference value for train control system in aspect of its inherent development pattern and practical achievements.By studying the evolution of mobile communication network architecture from 2G to 5G,and the structure and function changes of radio access network,the evolution pattern of mobile communication network is summarized:structural flattening,function prefabrication and hardware virtualization.This pattern is used to explain the practice represented by the integration of interlocking and train control,and possible development trend is proposed,including the perception of direct connection at the execution end of decision-making and transferring business functions on-board.
