The embodiment of the present invention discloses a control method, device and system for an electronic emergency valve of a locomotive brake, including obtaining the train pipe pressure value at the current moment and the decompression change rate of the train pipe at the current moment; judging the train pipe pressure value at the current moment During the first preset time, whether it is continuously greater than the first preset pressure value; if so, judge whether the train tube decompression change rate at the current moment is greater than the preset train tube change rate within the second preset time; if the If the train pipe decompression change rate at the current moment is greater than the preset train pipe pressure change rate within the second preset time, it is judged whether the train pipe pressure value at the current moment has dropped to greater than the second preset pressure value; if the If the pressure value of the train pipe at the current moment drops to greater than the second preset pressure value, the electronic emergency valve trigger command will be output to drive the electric air release valve to release air, so as to ensure that the electric air release valve can also be driven when the emergency valve fails to increase train operation. security.
Description
technical field [0001] The invention relates to the technical field of electronic emergency valves for locomotive brakes, and more specifically, to a control method, device and system for electronic emergency valves for locomotive brakes. Background technique [0002] The function of the locomotive emergency valve is to quickly exhaust the pressure of the train pipe when the locomotive is in emergency braking, and improve the sensitivity of emergency braking, thereby increasing the emergency braking wave speed of the train. At present, the traditional DK locomotive brake is equipped with two kinds of emergency valves, one is the pneumatic emergency valve, which realizes the emergency air release of the train pipe according to the air exhaust rate of the train pipe and generates an electrical signal for hook breakage protection, and the other is the electric air release valve , it realizes the emergency ventilation of the train tube according to the electrical signal, which c...
