CTC系统的列车启动停稳计算优化方案设计

Calculation Optimization of CTC Train Starting and Stopping Time in CTC System

高速铁路行车调度系统根据站场采集信号变化,逻辑推算列车启动停稳时分,并上报列车到发时刻生成实际运行图。由于既有启停推算逻辑存在计算粗糙、精度漂移等缺陷,导致到发时刻与实际运行图存在偏差,影响后续排路逻辑,因此,优化调度系统中列车启动停稳判定逻辑,对提升实际运行图精度,合理安排以列车启停时分为基础的排路操作,具有现实意义。

At present,the traffic control system for high-speed railway calculates the starting time and stopping time of the trains logically based on signal changes acquired from the stations and then reports the arrival and departure time of the trains to generate the actual train diagram.H ow ever,the defects in the existing calculation logics,such as rough calculation and accuracy drift,might lead to the deviations of train arrival and departure time from the actual train diagram,thus affecting the subsequent routing logics.Therefore,optimizing the logics to determine the starting and stopping time of the trains in the traffic control system is of practical significance for improving the accuracy of the actual train diagram and arranging proper train routing in subsequent operations.
