The embodiment of the invention discloses a control method, device and system of a locomotive brake electronic emergency valve. The control method includes the steps that the pressure value of a train pipe at the current moment and the pressure reduction change rate of the train pipe at the moment are obtained; whether the pressure value of the train pipe at the moment is continuously larger than the first preset pressure value or not in the first preset time is judged; if yes, whether the pressure reduction change rate of the train pipe at the current moment is larger than the preset train pipe change rate or not in the second preset time is judged; if the pressure reduction change rate of the train pipe at the moment is larger than the preset train pipe change rate in the second preset time, whether the pressure value of the train pipe at the moment is lowered to be larger than the second preset pressure value or not is judged; if the pressure value of the train pipe at the moment is lowered to be larger than the second preset pressure value, an electronic emergency valve trigger command is output, an electric snorting valve is driven to discharge air, so that it is guaranteed that when the emergency valve fails, the electric snorting valve can be driven, and the running safety of a train is improved.
