基于GPS机车实时运行数据传输系统设计与研究(英文)

The research and design of transmission system of real-time locomotive's operation information based on GPS

研究机车实时运行信息传输系统设计问题。该系统基于差分全球定位系统 (DGPS)、现有铁路机车无线调度通信系统和铁路专用通信网络技术。DGPS主要用来精确确定机车实时运转位置 ,数话同传子系统利用现有机车无线调度电台将机车实时信息传至铁路沿线的地面计算机通信系统后再分别送至各有关调度中心和机务部门。

This paper suggests a design of transmission system of real-time locomotive's operation information based on GPS with train dispatching radio communication system and railway packet switched networks. Differential GPS is adopted to locate locomotives accurately,as well as data-voice synchronous communication system is used to transfer locomotives' real-time operating information. Ground computers can receive the information through the railway packet switched networks. The transmission system consists of three subsystem: GPS locomotive location subsystem, Data-voice synchronous wireless dispatching communication subsystem, Ground data transmission subsystem.
