基于ATO的列车牵引计算算法设计与实现

为了实现基于自动驾驶(ATO)的列车牵引计算系统,将牵引计算自动算法设计为工况初选、回退优化和试凑3部分.工况初选在考虑列车运行坡段线路的实际情况下,结合列车的各种约束使列车运行;列车运行出坡时若列车的出坡速度不满足出坡检验,则选取相应的回退策略进行工况重新优化组合;在列车越过坡段后进行出坡速度试凑,列车进站时进行速度和距离试凑.模拟仿真显示该算法具有较强的实用性.

Design and implementation of arithmetic of train traction calculation based on auto train operation

In order to implement Train Traction Calculation System based on automatic train operation,automatic arithmetic of traction calculation was divided into three parts of initial choice of working condition,back-off optimization and cut and try.Initial choice of working condition took into consideration real situation of railway line and made train to run at meeting various constrains.The working condition of train was obtained optimization over again according to different strategies of optimization if speed of train at end of gradient done not meet request.Cut and try on speed of train at end of gradient,speed of train at station and stopping distance at station were carried out.Simulation showed that the arithmetic proposed to take on better applicability.
