The invention discloses a method for predicting the workload of shunting operation of a station. The method comprises the following steps: firstly, constructing time sequence data for measuring the workload of the shunting operation through wireless shunting locomotive signals and STP data of a monitoring system; distributing sub-sequence data of the constructed time sequence data to Hadoop cluster nodes, dividing a DTW distance matrix into a plurality of sub-matrixes, and obtaining a time sequence DTW distance by adopting a parallel computing method; and searching a scene with the highest similarity with the current data in the data over the years according to the obtained DTW distance, and predicting the workload of the shunting operation of the station on the basis of the scene. The method can effectively predict the shunting operation workload of the station in a specific time period, carries out the proper allocation of transportation resources according to the workload, and provides a judgment basis for the related departments of the railway in transportation scheduling command.

    本发明公开了一种车站调车作业工作量的预测方法,首先通过无线调车机车信号和监控系统STP数据构建衡量调车作业工作量的时序数据;将所构建的时序数据的各子序列数据分发到Hadoop集群节点上,将DTW距离矩阵划分成多个子矩阵,采取并行计算的方法得到时间序列DTW距离;根据所得到的DTW距离搜索在历年数据中与当前数据相似度最高的场景,并以此为依据来预测车站调车作业工作量。该方法能有效预测车站在特定时段的调车作业工作量,并据此进行运输资源的适当调配,给铁路相关部门在运输调度指挥上提供判断依据。
