摘要
目前,随着城市轨道交通业务的发展,车地通信业务要求不断提高,特别是运营安全需求方面成为重点,在网络化运营管理以及列车视频多路、高清双向传输等方面也提出高可靠、高稳定的需求。对城市轨道交通传统使用的WLAN技术和新近建设中使用的LTE技术,从组网结构、高速移动、抗干扰能力、稳定可靠等方面进行对比分析,并对LTE技术的应用前景及开发方向进行了展望。可以预见,在新近城市轨道交通建设中,LTE技术将成为应用主流。
At present, with the development of urban rail transit service, train-ground communication service requirements continue to be higher, and become the focus of demand and requirements of operational safety especially. Meanwhile, it has high reliability and high stability requirements on network operation management, and train video multi-channel and HD two-way transmission etc. As urban rail transit uses the traditional WLAN technology and LTE technology in the new construction, this paper makes analysis from aspects of the network structure, high speed motion, anti- interference capability, stability and reliability etc. The future application and development direction of LTE technology is prospected, and it is expected that LTE technology will become the mainstream in the application of new rail transit construction.
