基于5G通信的铁路车载大数据车地传输方案研究

Research on Railway Onboard Big Data Transmission Scheme Based on 5G Communication

随着我国铁路路网规模的迅速扩大,以及基础设施、移动装备的健康管理数字化和智能化发展,越来越多的机车、动车组和检测车投入运营,车载设备所产生的数据也呈指数级增长。为了研究高效、可靠、安全的车地数据传输技术,实现车载大数据实时传输,本文结合5G通信在我国铁路应用中的发展趋势,基于5G通信传输特点和铁路车地通信场景,提出正线和站场采用公网5G和铁路专网5G-R、站场补充采用5G毫米波点对点通信的车载大数据车地传输方案,为铁路设备健康管理和安全运营提供技术支持。

With the rapid expansion of Chinese railway network and the development of intelligent and digital technologies for health management of infrastructure and mobile equipment,more and more locomotives,EMU trains and inspection cars are put in operation in China,the data generated by on-board equipment is also growing exponentially.Therefore,it has become an urgent task to study efficient,reliable and safe train-ground data transmission technology to realize real-time transmission of on-board big data.To follow the development trend of 5G communication in Chinese railways,and combines the characteristics of 5G communication transmission and railway vehicle-ground communication scene,the train-ground on-board big data transmission scheme is proposed in which 5G public network and 5G-R railway private network are adopted for both railway lines and stations and 5G millimeter-wave point-to-point communication is also adopted for stations as supplements,providing technical support for health management of equipment and safe operation of railway.
