摘　　要：铁路物联网承载层需要将感知层获取的信息,经通信网络安全可靠地传输到应用层.目前承载层技术有多种,本文主要研究铁路物联网承载层的架构,提出以GPRS技术为主的多种技术并存的铁路物联网承载层体系,并对该承载层的关键技术需求进行阐述.The carrier layer of the Internet of Things for railway is required to transm it the data obtained by the perception layer to the application layer safely and reliably over communication network.At present,there are many kinds of carrier layer technology.This paper focuses the study on the framework of the carrier layer of the Internet of Things for railway which is mainly based on GPRS technology with the coexistence of a variety of technologies.And key technologies of the carrier layer are expounded.
