TRAIN BRAKING CONTROL METHOD AND DEVICE SUPPORTING MULTI-STAGE DECELERATION, AND STORAGE MEDIUM

A train braking control method and device supporting multi-stage deceleration, and a storage medium are provided. The method includes the following steps: calculating an initial value of kinetic energy of a train; calculating work of traction force of the train in a process from an initial position to traction removal; calculating work of gravity force of the train in a process from the initial position to a stop; calculating work of braking force of the train in a process from a braking application position to the stop; calculating maximum allowable kinetic energy of the train among all restriction points from the initial position to a stop point; obtaining kinetic energy of the train according to the following formula, determining whether the kinetic energy of the train exceeds the maximum allowable kinetic energy at the restriction point, if so, triggering emergency braking of the train, or else, operating the train normally.
