现代铁路信号系统研究

Study on Modern Railway Singaling System

我国铁路通信系统已经形成了完整的信息网络，这标志着中国现代铁路建设的开始，为现代化铁路和21世纪ITS的建设奠定了信息技术基础。同时，也为现代铁路信号系统提供了技术基础。本文对铁路通信和信号系统的技术特点进行了讨论，提出了以铁路基础信息网、开放式现场总线为技术基础的智能化、网络化的现代铁路信号系统。这种系统彻底改变了传统铁路通信信号系统通信系统与信号系统相隔绝的状态。

The all -round railway infrastructure was found in our country,which is the mark of the start of modern China's railway construction and the information base of ITS in next century. In the mean time,it is supplied a basic technology for China's modern railway signaling system. According to the discussion of railway communication and signaling system technical properties,this paper addressed an intelligent and networking railway signaling system,which is supported by the railway infrastructure,and opening fieldbus technology.
