Problems solved by technology
[0004] It can be seen from the above that in the prior art train-level air-electric composite braking mode, the head car brake control unit needs to summarize and calculate the train load of the train, the maximum available value of the train electric brake and the maximum available value of the train air brake. When the brake control unit of the head car or the brake control unit of the end car breaks down, it is easy to cause the brake failure of the train or the traction unit, which will seriously affect the safety of the train

The invention provides a rail train brake control system and a rail train brake control method. Brake control units in each compartment are arranged for receiving train brake commands and respectivelycalculating the load, the electric brake maximum available value and the air brake maximum available value of the compartment, the load, the electric brake maximum available value and the air brake maximum available value of a traction unit in which the compartment is located, and the load, the electric brake maximum available value and the air brake maximum available value of the train, and finally performing calculating to obtain an electric brake force applying value and an air brake force applying value of the compartment. According to the control system and the control method disclosed by the invention, the unit electric brake maximum available value and the unit air brake maximum available value of the traction unit in which each compartment is located, and the train electric brakemaximum available value and the train air brake maximum available value of the rail train can be updated in real time according to the condition of the compartment, so that the technical problem thatin the prior art, the brake of the rail train fails caused by that a head train brake control unit or an end train brake control unit is broken down, the brake stability of the rail train brake control system is improved, and the travelling safety of the rail train is further improved.
Description
technical field [0001] The invention belongs to the technical field of rail train braking, and in particular relates to a rail train braking control system and a control method. Background technique [0002] Rail trains generally include several traction units, and each traction unit includes several carriages. The carriages are divided into motor car carriages and trailer carriages. The motor carriages can perform electric braking and air braking, while the trailer carriages can only perform air braking. The core component of the rail train brake control system is the brake control unit installed on each carriage. [0003] At present, the brake control system of rail trains mainly adopts the air-electric composite braking mode. The air-electric composite braking mode is to use electric braking first. When the electric braking is insufficient, it is supplemented by air braking. The air-electric composite braking mode is divided into a single-vehicle-level composite braking ...
