Train braking planning method based on predicted speed

The invention provides a train braking planning method based on predicted speed, which comprises the following steps: S100: when a train braking instruction is received, calculating braking force required by a train according to braking parameters of the train; s200, train braking is controlled according to the calculated braking force, the real-time displacement of the train in the braking process is obtained, and the speed of the train is predicted according to data of the real-time displacement; and S300, the braking force applied to the train is adjusted in advance according to the prediction result, and the step S200 is repeated till the train is completely braked. According to the method, the displacement of the train is predicted in advance, then the magnitude of the applied braking force can be adjusted in time according to the sliding speed of the train in the braking process in advance, the braking efficiency is improved, meanwhile, severe friction of wheel rails is avoided, and the better braking e
