Station shunting operation workload prediction method

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of railway transportation research, in particular to a method for predicting the workload of station shunting operations. Background technique [0002] Balanced transportation is an important principle of railway transportation organization. Each station basically has fixed transportation resources, but this method will cause waste or tension of transportation resources, that is, the use of transportation resources is unreasonable. It is one of the important topics in the current railway transportation research to rationally match and use transportation resources according to the busyness of operations, and to improve the organization method of station operations and the efficiency of shunting operations. The wireless shunting locomotive signal and monitoring system (STP,ShuntingTrain Protection) is an important auxiliary equipment for shunting safety protection, through its ground equipment, it processes th...

Problems solved by technology

[0003] In the prior art, the measurement of shunting work workload is simply to count the macro indicators such as the number of unloaded trailers and the number of unhooked trailers per year. It cannot measure the shunting work workload in all aspects from the perspective of big data, and lacks prediction. Solution to the Workload of Station Shunting Operation
