【摘要】 提出的单线铁路调度监督系统具有定位、通信、地图匹配及显示和必要的辅助功能。采用GPS、行车监控仪和查询应答器相结合的列车定位系统 ,实现对单线铁路列车的定位。在平原地区 ,且不需分辨列车经由的站场线路时 ,仅采用GPS即可。在隧道等GPS信号盲区 ,可采用行车监控仪。在车站则可利用现有的电气集中轨道电路精确定位。定位信息的传输建议采用GSM R和TETRA系统。GIS电子地图则可根据铁路的特点开发 ,并采用一些简化算法进行匹配更多还原

【Abstract】 The proposed dispatchers supervision system for single track railway comprises positioning, communication, map matching functions and some necessary auxiliary functions. Generaly, the positioning of trains on single track railway can be implemented using a train positioning system integrating GPS, train monitor and transponder. But in plain regions, when there is no need to differentiate the track a train passes through in railway yard and station, the positioning job can be done with GPS only. In the blind areas of signals such as in tunnels, train monitors are workable for positioning. At railway stations, a precise positioning can be realized by means of the existing track circuits for electric interlocking. GSM R and TETRA systems are advised to transmit the positioning information. GIS electronic maps have been developed according to the one dimentional characteristic of railways using some simplified algorithms.更多还原
