The invention provides a control method and device for train emergency braking. The method comprises the steps that an emergency braking instruction and the current running speed of a train are periodically received; according to the current running speed and the emergency braking control strategy, a bicycle control instruction of each bicycle is obtained; wherein the emergency braking control strategy comprises a plurality of speed grades and a single vehicle control instruction corresponding to each speed grade, the plurality of speed grades are predetermined based on the marshalling number of the train and the transformation proportion of the relay valve, and the single vehicle control instruction is used for adjusting the transformation proportion of the relay valve of a single vehicle; and the bicycle control instruction of each bicycle is sent to the bicycle control unit of each bicycle, so that the bicycle control unit of each bicycle performs emergency braking control based on the corresponding bicycle control instruction. The device is used for executing the method. According to the train emergency braking control method and device provided by the embodiment of the invention, the adhesion utilization of the train in a high-speed section is increased, and the emergency braking distance is reduced.
本发明提供列车紧急制动的控制方法及装置,所述方法包括:周期性接收紧急制动指令和列车的当前运行速度;根据当前运行速度以及紧急制动控制策略,获得每个单车的单车控制指令;其中,紧急制动控制策略包括多个速度等级和每个速度等级对应的单车控制指令,所述多个速度等级是基于列车的编组数量和中继阀的变换比例预先确定的,单车控制指令用于对单车的中继阀的变换比例进行调整;发送每个单车的单车控制指令给每个单车的单车控制单元,以使得每个单车的单车控制单元基于对应的单车控制指令进行紧急制动控制。所述装置用于执行上述方法。本发明实施例提供的列车紧急制动的控制方法及装置,增加列车在高速度段的黏着利用,减少了紧急制动距离。
