Abstract

The rail train braking control method and device provided by the present invention are applied in the technical field of rail trains. When the backup master BCU obtains the total braking force of the train when the communication with the master BCU is interrupted, the backup master BCU first determines the slave that can establish a communication connection. BCU, get the target slave BCU to build the CAN unit controlled by the standby master BCU, then perform train-level braking force distribution to obtain the unit braking force, and then send the unit braking force to each target slave BCU to make the CAN unit controlled by the standby master BCU Each BCU in the system controls the corresponding braking mechanism to brake according to the obtained unit braking force. Through this method, in the case of interruption of communication with the master BCU, the standby master BCU can still control the slave BCU that can establish a communication connection to perform braking. The braking force loss of the rail train is reduced to the greatest extent, and then the braking distance of the rail train is effectively controlled to ensure the safety of the rail train.

Description

technical field [0001] The invention belongs to the technical field of rail trains, in particular to a braking control method and device for rail trains. Background technique [0002] Most of the existing rail train braking control systems use MVB (Multifunction Vehicle Bus, multifunctional vehicle bus) and CAN (Controller Area Network, controller area network) two-layer communication network for braking force control. figure 1 It is a schematic diagram of the network structure of the rail train braking control system, such as figure 1 As shown, for a 6-car train consisting of 6 car bodies, it can be divided into two CAN units, CAN1 and CAN2. In any CAN unit, multiple BCUs (Brake control units, brake control units) are included. According to different specific functions, it can be subdivided into a master BCU (Brake control unit, brake control unit), a backup master BCU and several slave BCUs. Each BCU in the same CAN unit communicates through the CAN bus and is allocated b...
