动车存车场走行线信号系统控制方案研究

Research on Control Scheme of Signaling System at Running Tracks of EMU Stabling Yard

研究动车存车场走行线相关的信号系统控制方案,以期确保运输能力及提升路网效益,同时控制工程建设成本。研究结论:(1)车站与存车场间采用列车作业方式时,为缩短存车线线路长度,应在存车线中部设置定位应答器,以节约整体工程投资。(2)走行线长度不大于1500m时,受车载ATP设备车尾保持限速及地面轨道电路发码的影响,实际最高车速通常低于线路设计最高速度,因此走行线速度等级、曲线半径等设计应与实际最高车速相匹配。(3)走行线采用调车作业方式时,安全性由ATP设备保障,运营管理方式更为灵活,综合经济效益评价更优。

This paper researches the control scheme of signaling system at running tracks of the EMU stabling yard,so as to assure the transport capacity,improve the efficiency of the road network,and control the construction cost.Research conclusions are as follows:(1)When the train operation mode is adopted between the station and the stabling yard,a positioning balise should be installed in the middle of the stabling siding,so as to shorten the length of the stabling siding and save the overall project investment.(2)When the length of the running track is less than 1500 m,the actual maximum speed is usually slower than the maximum design speed of the line due to the restriction by the tail retention speed limit of ATP equipment and the coding transmitting of the track circuit.Therefore,the speed class and curve radius of the running track should be designed to match the actual maximum speed.(3)When running tracks are in shunting operation mode,ATP equipment will ensure safety,the railway operation and management become more flexible,and the comprehensive economic benefit evaluation will be better.
