改进列车运行图编制技术充分利用现有提速资源

Mend the Compilation Technology of Train Graph, Make Full Use of Current Speed-Raising Resources

既有线提速投资很大 ,但因现行铺画运行图是以 0 2 5min为最小时间单位 ,机车运行标尺和机车监控记录装置也以此为标准 ,致使现有实际能达到的提速资源不能充分利用。使用计算机编图可以“秒”为单位进行铺画 。

There has been large investment for speed raising on existing lines. However, the current layout of train graph is based on the standard of 0.25 minute as the minimum timing unit. It is also the standard of staff guage for locomotive operation and locomotive supervision recording device. Thus the exact resources of speed raising can not be fully utilized in current situation. To design the train graph by computer based on timing unit of 'second', the speed raising resources can be fully used and the target of saving largely the investment of line modification can be achieved.
