摘要
公专网技术在重载货运车-地通信线路中的应用,对重载铁路公专网进行监测成为保障网络安全稳定运行的重要技术手段.简要论述目前实际应用在重载货运线路的LTE公专网架构,并对公专网监测系统的结构、功能、接口及关键技术进行论述.研究针对在车载侧、地面侧乃至中心侧全链条的监测技术,最终对重载铁路公专网监测系统未来的推广进行展望.
Abstract
With the application of public and private network technology in heavy haul freight vehicle-ground communication lines,monitoring the public and private networks of heavy haul railways has become an important technical means to ensure network security and stable operation.This paper briefly discusses the LTE public and private network architectures currently applied in heavy haul freight lines,and discusses the structure,functions,interfaces,and key technologies of the public and private network monitoring system.The research focuses on monitoring technology for the entire chain,including technology for the onboard side,the ground side,and even the center side,and ultimately provides prospects for the future promotion of heavy haul railway public and private network monitoring systems.
