Description

Technical field [0001] The present invention belongs to the field of rail transit, and more particularly to a train brake curve segmentation method, system, and train control method. Background technique [0002] Train operation control system (referred to as column control system) is an important driving equipment that guarantees the safe operation of the train, and is composed of vehicle equipment and ground equipment. Automatic Train Protection, ATP) is a vehicle device of the column control system, which generates a brake distance curve based on the line data, temporary speed limit provided by the ground device, generates a brake distance curve based on the train braking performance parameters. [0003] When the train system calculates the train distance curve, in order to simplify the amount of computation, the transmissive efficiency, the train brake curve with a dense train brake performance parameter point is usually segmented, that is, segment the intensive brake perform...
