A kind of brake control method of train carriage, train carriage and train

Abstract

An embodiment of the present application provides a train car braking control method, the steps of which include: obtaining the current number of train formations; obtaining the current carriage number and carriage type; calculating the current carriage number based on the train braking command and the current number of train formations braking force, and perform braking control on the current car. The technical solution described in the application can use real-time acquisition of the number of formations of the trains in the case of any formation of each train, and calculate the braking force required for each carriage according to the number and type of the current carriages, and perform braking control on the trains, It can ensure the normal operation of the brake control under the condition of flexible marshalling, and is not limited by the adjustment of the sequence of vehicles or the adjustment of car marshalling. In this solution, since the brake control unit BCU of each car is no longer divided into master and slave, the control level of the BCU of each car is the same, and they are mutually redundant, thereby reducing the use of single-car BCUs and reducing operating costs.

Description

technical field [0001] The present application relates to rail transit technology, and in particular, relates to a train car brake control method for a free marshalling train, a train car and a train. Background technique [0002] my country's existing EMUs are mainly composed of 8 cars, and operate in the mode of reconnection of the existing 8 cars, 16 cars and two 8 cars. But the marshalling mode of present EMU is fixed, and the position and direction of each car in the whole train have been stipulated in the design, and its marshalling type cannot be changed, and the number of cars contained in the train cannot be changed. Therefore, it is an urgent need to design EMUs that are easy to maintain, meet the needs of different traffic volumes, have flexible marshalling, and have good operating benefits. [0003] The braking system is a key technology of the rail transit system, and it is also one of the important guarantees to ensure the operation of flexible marshalling tra...

Problems solved by technology

[0006] The function of the segment brake manager (SBM) of the second layer is integrated in the two BCUs of the head car, and it is the main BCU in the brake control system of the current vehicle formation, such as figure 1 As shown, BCU1.1 and BCU1.2 are mutually redundant, that is, both BCU1.1 and BCU1.2 are equivalent to the leader of this section, but they cannot perform the function of SBM at the same time

Therefore, this braking control strategy for fixed-group trains cannot be applied to variable-group trains
