Abstract

The invention provides a rail train brake control method and device. The method is applied to the technical field of rail trains. A obtains the total braking force of the train under the condition that the communication between the standby main BCU and the main BCU is interrupted; the standby main BCU determines a slave BCU capable of establishing communication connection to obtain a target slaveBCU, and a CAN unit controlled by the standby main BCU is constructed; train-level braking force distribution is carried out to obtain the unit braking force, then the unit braking force is sent to each target slave BCU; therefore, each BCU in the CAN unit controlled by the standby main BCU controls the corresponding brake mechanism to brake according to the obtained unit brake force. By means ofthe method, under the condition that communication with the main BCU is interrupted, the standby main BCU can still control the slave BCU capable of establishing communication connection to conduct braking, the braking force loss of the rail train can be reduced to the maximum degree, then the braking distance of the rail train is effectively controlled, and the running safety of the rail train isguaranteed.

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...
