Description

technical field [0001] The embodiments of the present invention relate to the technical field of transportation, and in particular to a training of a current prediction model, a current prediction method and related devices. Background technique [0002] At present, in subways, BRT (Bus Rapid Transit, BRT) and other transportation systems, stations usually arrange platform doors along the edge of the platform to isolate the platform from the traffic area, reduce the operating energy consumption of the station’s air conditioning and ventilation system, and reduce The impact of train running noise and piston wind on the station prevents accidents caused by people falling off the track, and provides passengers with a comfortable and safe waiting environment. [0003] When the train arrives at the station, the platform door is opened, passengers can get on and off the train through the gate, then the platform door is closed, and the train continues to run. When the platform doo...
