铁路通信工程应用接入网技术综述

Comprehensive Review on Technology of Applied Access Network for Railway Communication Engineering

铁路事业是社会发展的重要推动力量,技术革新势在必行。本文聚焦于铁路通信工程应用接入网技术,分别从发展现状、应用特点、存在的问题展开了论述,表明有线接入仍是当前应用接入网技术的主要方式,其应用具有多样性、经济性、灵活性等特点,而参考资料匮乏、稳定性不强、传输速度受限是其技术发展瓶颈。为适应发展趋势,铁路通信应勇于摆脱传统理念的桎梏,积极吸取电信通信等无线领域的宝贵经验,为建设高效、实时、可靠的现代化铁路提供有力保障。

Railway,as an important driving force for social development,urges technological innovation.Focusing on the technology of applied access network,a discussion is carried out from aspects includingits status quo,application characteristics and existing problems.Such a discussion indicates that,wiredaccess is still the main way of current applied access work,which is of diversity,economy and flexibility.Its technological developmentbottlenecks include lack of reference materials,weakness of stability andlimitedtransmission speed.In order to adapt to the development trend,railway communication musthave thecourage to get away from the shackles of traditional view,and actively absorb the valuable experiences ofother wireless fieldsincluding telecommunication,to provide a strong guarantee for the construction of modernrailwaywith efficiency,real-time and reliability.
