摘要
为解决由城轨环境特殊性导致的通信可靠性、时延性能降低以及运营效率瓶颈等问题,首先从整体运营控制的角度分析了城轨通信需求。结合新型智能运行控制技术及T2T(train to train,列车到列车)通信、5G、人工智能、移动边缘计算等新兴信息技术对城轨通信关键技术进行梳理、总结与展望;然后提出了一种新型城轨通信网络架构,最后探讨了智慧城轨通信技术的研究方向与面临的挑战,为智慧城市的发展提供研究基础。
The particularity of the urban rail transit environment leads to the problems such as reducing communication reliability,delay performance and operating efficiency bottlenecks.Therefore,the demand for urban rail communication was analyzed from the perspective of overall operational efficiency.New intelligent communication control technologies such as T2T(train to train)communication,5G,artificial intelligence,and mobile edge computing were combined to summarize and prospect the key technologies of urban rail communication.Then,a new type of urban rail communication network architecture was proposed.Finally,the research direction and challenges of smart urban rail communication technology were discussed,which also provided a research foundation for the development of smart cities.
