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

Embodiment Construction
[0050] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the exemplary embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only part of the embodiments of the present application, and Not an exhaustive list of all embodiments. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0051] The core idea of this scheme is to obtain the latest number of train formations in real time in the case of free formation of trains, calculate the braking force required for each carriage according to the number and type of each carriage, and perform braking control on the train to avoid formation After the number changes, the brake control unit BCU needs to be changed, replaced and tested accordingly, so a...

An embodiment of the invention provides a train carriage braking control method. The method comprises steps as follows: acquiring the current train marshaling quantity; acquiring the number and the type of a current carriage; calculating braking force of the current carriage according to a train brake instruction and the current train marshaling quantity, and conducting brake control on the current carriage. According to the technical scheme, under the condition of random marshaling of each train, the braking force required by each carriage is calculated according to the real-time acquired train marshaling quantity as well as the number and the type of the current carriage, and brake control is performed on the train, so that normal operation of brake control under the condition of flexible marshaling can be guaranteed and is not limited by train order adjustment or carriage marshaling adjustment. According to the scheme, BCUs (brake control units) of the carriages are free of primary-secondary difference, have the same control level and are mutually redundant, so that BCU use of a single carriage is reduced, and operating cost is reduced.
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...
