  • Train overspeed protection method and apparatus
    Patent number: 11396312
    Abstract: A train overspeed protection method includes: acquiring, when emergency braking is triggered for a train, an initial speed limit location point of each speed limit region among a preset number of speed limit regions, and a first speed limit value corresponding to each initial speed limit location point so as to obtain a plurality of first speed limit values; acquiring a current traveling location point of the train and a corresponding second speed limit value, and acquiring a current traveling speed of the train; determining a plurality of decelerations of the current traveling speed relative to each first speed limit value, selecting a deceleration satisfying a preset condition from the plurality of decelerations, and determining the initial speed limit location point corresponding to the deceleration satisfying the preset condition as a target speed limit location point; determining an emergency braking speed according to a relative deceleration of the second speed limit value relative to the first speed li
