摘　　要：在铁路车站信号装置持续增加的背景下,用光纤代替电缆进行信号传输是一种必然趋势。光纤通信除了提高信息传输速度外,还能简化传输线路、降低敷设成本。使用了光纤通信技术的铁路车站信号系统,利用光纤将上位机、连锁计算机、驱动装置和室外设备等联系起来,通过终端指令的下达和前端数据的上传,保证了整个控制系统的稳定和可靠运行。本文首先介绍了铁路车站信号控制系统的基本组成,随后分别从进路控制、取消进路和人工解锁等方面,概述了铁路车站信号系统控制功能的实现。最后通过构建仿真模型,进行了进路选路的仿真实验。结果表明,仿真系统能够准确判断选路操作是否合法,并选出正确的进路。Under the background of the continuous increase of signal devices in railway stations,it is an inevitable trend to use optical fibers instead of cables for signal transmission.In addition to improving information transmission speed,optical fiber communication can simplify transmission lines and reduce installation costs.The railway station signal system using optical fiber communication technology uses optical fiber to connect the host computer,chain computer,driving device and outdoor equipment,etc.,and ensures the stable and reliable operation of the entire control system through the issuance of terminal commands and the upload of front-end data..This paper first introduces the basic components of the railway station signal control system,and then summarizes the realization of the railway station signal system control functions from the aspects of access control,cancellation of access and manual unlocking.Finally,by constructing a simulation model,the simulation experiment of route selection is carried out.The results show that the simulation system can accurately judge whether the routing operation is legal and select the correct route.
