| description | The invention provides a locomotive braking starting moment predicting and positioning method and device, and the method comprises the steps: obtaining the pipe pressure data of a brake cylinder of a locomotive, the pipe pressure data being the data of the pipe pressure of the brake cylinder changing with time; selecting the pipe pressure data with a preset length for each time point in the pipe pressure data in sequence, and calculating a slope applied to the time point based on the selected pipe pressure data; and the locomotive braking starting moment is determined according to the slopes corresponding to the time points in the pipe pressure data. According to the method, the change trend of the pipe pressure can be accurately judged, and accurate positioning of the starting moment of braking applied by the locomotive crew is achieved.
