Problems solved by technology

When the user needs to know the information of a certain type or all vehicles passing through the specified station within the specified time period, it is necessary to search and count all the vehicles passing through the specified station within the specified period according to the traffic flow estimation results. However, the traffic flow estimation results are based on vehicles Indexes are not suitable for direct statistical use, so it is necessary to perform time conversion on the traffic flow estimation results, and use the traffic flow data slices to process the results as time-based indexes

Abstract

The invention provides a railway vehicle flow data slicing method and apparatus. The method comprises the steps of performing slice division according to preset data slice quantity and data slice query time range, and generating a data cache corresponding to each slice; and obtaining a vehicle flow calculation result, determining a slice corresponding to a vehicle at a station according to arrivaltime and departure time of each vehicle at each station in a vehicle flow path in the vehicle flow calculation result, and storing information of the vehicle at the station in the data cache of the slice corresponding to the vehicle at the station. The vehicle flow calculation result can be processed into vehicle-time-position slices of vehicle flow data, thereby realizing time conversion of thevehicle flow calculation result.

Description

technical field [0001] The invention relates to the technical field of railway transportation dispatching, in particular to a method and device for slicing railway traffic flow data. Background technique [0002] The railway traffic flow estimation method can calculate the arrival time and departure time of each vehicle at a designated station by making statistics on all traffic flows. When the user needs to know the information of a certain type or all vehicles passing through the specified station within the specified time period, it is necessary to search and count all the vehicles passing through the specified station within the specified period according to the traffic flow estimation results. However, the traffic flow estimation results are based on vehicles Indexes are not suitable for direct statistical use, so it is necessary to perform time conversion on the results of traffic flow calculations, and use the traffic flow data slices to process the results as time-ba...
