摘要:
采用信息、人员、设备协同联动技术,基于4G专网(站车交互网)和铁路综合信息网,研究了移动互联条件下的站车无线交互技术。基于该技术,铁路行包信息系统具备与铁路客运信息系统进行网络互联、数据合理对接和基础设施共享的条件。依托国铁集团安全平台,与客票发售与预订系统共享站车交互网络,提出铁路行包信息系统无线交互的网络架构,明确了数据的交互内容及频次,可为数据接口规范、交互标准及安全交互策略的制定提供参考。通过对京沪线部分车次和行包办理点进行行包系统业务数据交互实验,验证基于4G专网进行站车无线交互的可行性。
Abstract:
Based on 4G special network (station and train interaction network) and railway integrated information network, this paper studied the wireless interaction technology of station and train under the condition of mobile interconnection. Based on the wireless interaction technology, the railway luggage and parcel information system would have the conditions of network interconnection, data reasonable connection and infrastructure sharing with the railway passenger transport information system. Relying on the safety platform of China Railway, sharing the station and train interaction network with the railway ticketing and reservation system, the paper put forward the network architecture of wireless interaction of luggage and parcel system, clarified the content and frequency of data interaction, adopted the unified data interface specification and interface standard, and gave the interactive information security strategy. Through the business data interaction experiment of some train numbers and luggage and parcel handling points of Beijing Shanghai Railway Line, it is verified the feasibility of wireless interaction of station and train based on 4G special network, and improved the wireless interaction level of railway baggage information system to a certain extent.
