【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已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。 在电子设计技术领域，可编程逻辑器件以其高可靠性、高速度、低功耗在国际上得到广泛应用，为数字系统的设计带来革命性的进步。在我国该项技术的发展尚处于初级阶段，但已日益受到关注。 本论文围绕如何使用可编程逻辑器件来实现高速、稳定、大容量、可靠性好的车站安全信息光纤局域网，对可编程逻辑器件设计应用技术、网络拓扑结构、网络的介质访问控制方法、数据通信协议进行了详细分析和论述，并提出了使用Altera ACEX 1K器件设计专用通信芯片，研发新一代高速铁路安全信息光纤局域网核心模块的技术解决方案。经过实验验证，作者设计的专用通信芯片能够稳定、正常、有效地工作，达到高速铁路安全信息光纤局域网设计要求。该项工作为今后铁路专用通信系统设备的设计和研发提供了很好的模式和经验。更多还原

【Abstract】 With the development of high-speed railway and increasing speed of running trains, the traditional signaling technology is not enough for the safely running of high-speed train, in which safety information transmits in copper cable. Using technology of optical communication, computer and network, the Local Area Network for safety information of high-speed railway can transmit the information effectively, reliably, real-timely.In the area of electronic design technology, Programmable Logic Device with high reliability, high speed and low power, widely used in the developed countries and make great progress for digital system’s design. Now the technology is at primary stage in China, but more and more professional engineer take attention to it.This paper mainly introduces how to design railway false-safe LAN with high speed, stability, great capacity and reliability by using Programmable Logic Device, analyzes the Programmable Logic Device technology, the topology structure, the media access control method and data link control protocol of the railway false-safe LAN, provides the solution using AlteraACEX IK device to design railway false-safe LAN’s core modules.The module in the trial works stably, effectively and completely meets the technical requirement of the design. This provides very good model and experience for dedicate communication system’s design and development for our railways in the near future.更多还原
