【摘要】 随着高速铁路的发展，列车运行速度的提高，传统的通过电缆传输车站安全信息方式己不能满足高速铁路安全运行的需要。高速铁路安全信息光纤局域网利用光纤通信技术、网络技术和计算机技术实现铁路安全信息的实时、可靠、高效传输，是铁路信号安全信息传输现代化的重要突破。 本论文通过对网络拓扑结构、网络的介质访问控制方法以及数据通信协议的分析，介绍了两种不同的高速铁路安全信息光纤局域网的实现方案。一种是专用的高速铁路安全信息光纤局域网；一种是铁路区间信息综合接入系统。本文还介绍了网络节点设备的软件、硬件设计和两套实验系统。通过实验证明，这两种方案均能安全、可靠、实时的传送铁路安全信息。更多还原

【Abstract】 With the development of high-speed railway and increasing speed of runingtrains, the used signalling technology is not enough for the safely running of high-speed train, in which safety information transmits in copper cable. Using technologyof optical communication, compuler and network, the Local Area NetWork for safetyinformation of high-speed railway can transmit safety signal more safely, reliably,real-timely lt is importan improvement in transmission of railway safety signal,In this thesis, after analysis of topology structure, media access control methodand data link control protocol, we discussed two netWorks. One is the high-speedrailway false-safe LAN. The other is the Integrated Information Access Network ofrailway These two networks are both for transmission of raiIway safety information.And in this thesis the software and hardwar of network node equipment wasdiscussed too. We have finished two networks for trial in lab. In trial, both of themcan transmit safety signal safely, reliably, real-timely.更多还原
