Taking rail transportation industry as the background, a framework of the "Internet of Things" for Smart Rail Transportation (SRT-IoT) was proposed and its key techniques were explored. With the perception of the next generation Internet, this framework was characterized by a Backbone Communication Network for SRT (SRT-BCN) interconnected by various Basic Access-Resource Networks (BARN) with clients and resource servers. Furthermore, rail-transportation specific BARNs were classified into two groups: Train-based Access-Resource Network (TARN) and Ground-based Access-Resource Network (GARN). Techniques feasible for different network were also analyzed in different details, and an emphasis had been given to TARN with a conclusion that TARN related network technologies should further develop as a research basis of SRT-IoT for wider interconnection.%以轨道交通行业为背景,以智慧轨道交通(SRT)为对象,研究智慧轨道交通“全联网”(IoT)的基本组成框架和关键技术.将IoT置于下一代Internet背景之中,提出了以“智慧轨道交通骨干通信网”(SRT-BCN)为核心、以“基础接入网-资源网络”为轨道交通信息源和受主网络的“智慧轨道交通全联网( IoT for SRT,SRT-IoT)”的系统组成框架.针对轨道交通行业的特点,进一步将智慧轨道交通基础接入—资源网中与轨道交通有关部分划分为“列车接入—资源网”(TARN)和“地面接入—资源网”(GARN),并分析智慧轨道交通骨干通信网(SRT-BCN)和外围接入/资源网的特点,讨论相关的关键技术.重点讨论了与列车相关的TARN技术,得出需要进一步发展TARN相关网络技术的结论,为实现SRT-IoT更广泛的互联互通奠定研究基础.
