城市轨道交通5G车地无线通信系统可实施性研究及智能应用探索

Study on the practicability of 5G wireless based train-ground communication systems and its inteligent applications in urban rail transit

随着城市轨道交通行业的快速发展和业务需求的日趋复杂,智慧运维已成为未来城市轨道交通发展的必然方向,车地无线通信技术面临新的挑战,采用大带宽、高速率、安全稳定的车地无线通信系统将成为发展趋势。长期以来,受制于车地无线网络带宽不足,存储于城市轨道交通列车中的大量数据,如车载CCTV数据和列车运行监测数据等无法及时回传到地面,极大的限制数据价值的发挥,故现有的城市轨道交通车地无线通信技术已经无法满足日益增长的车地通信需求。基于5G技术的AirFlash车地无线通信系统具备较强的可实施性,且有广阔的应用前景,能一定程度的解决目前城市轨道交通车地无线通信面临的难题,可提升列车智能运维水平,实现数字化转型。

With the rapid development of the urban rail transit industry and increasingly complex business requirements,smart operations and maintenance have become the inevitable direction of future urban rail transit development.Train-ground wireless communication technology faces new requirements,the train-ground wireless communication system with large bandwidth,high speed,safety,and stability will become the development trend.For a long time,due to insufficient bandwidth of train-ground wireless network,mass data stored in metro trains including on-board CCTV data and train operation supervision data are unable to be sent back to the ground in time,greatly limiting the value of data and failing to realize data analysis and application.The AirFlash train-ground communication system based on 5G wireless technology is feasible and has broad application prospects.To a certain extent,it can solve the issues faced by the current train-ground wireless communication of urban rail transit,improve the intelligent operation and maintenance level of trains and realize the digital transformation.
