Embodiment Construction

[0049]The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] At present, the train brake system and brake control method adopted by ordinary railway passenger trains at home and abroad all adopt automatic air brake. Pressurization and decompression achieved. During the operation of the train, the air pressure of the train pipe is charged to the set pressure (600kPa for passenger trains in my country, and 500kPa for ordinary freight cars), which is the pressure when the train relieves its ...

Abstract

The invention provides a train braking system and a braking control method. Related control components such as a change-over valve and a microcomputer control mechanism are arranged on a train; an airbrake valve originally arranged on a train is combined to jointly form a brake system of the train. The microcomputer control mechanism controls the switching valve to be opened based on the networkcontrol instruction to implement straight-through type electric pneumatic braking; the air brake valve implements automatic air brake based on the pressure change in the train pipe. During specific operation, a train is firstly subjected to straight-through type electric pneumatic braking, it can be guaranteed that all the trains receive braking or relieving instructions sent through network broadcasting at the same time, corresponding braking or relieving control is carried out, braking and relieving synchronism of all the trains in the train is almost completely consistent, and running stability of the train is guaranteed; Meanwhile, the pressure change of the train pipe also reaches each train and each air brake valve in sequence for automatic air brake, so that the hot standby redundancy function of train brake is provided.

Description

technical field [0001] The invention relates to the technical field of train braking, and more particularly, to a train braking system and a train braking control method. Background technique [0002] At present, the braking systems of all trains exist in two independent ways, namely the straight-through electro-pneumatic braking system and the automatic air braking system. The two types of braking systems can be used for train braking control respectively; Regular-speed passenger trains and freight trains use automatic air brakes, EMUs and urban rail transit generally use straight-through electro-pneumatic brakes, and most foreign trains (including EMUs) use automatic air brakes; Japanese EMUs all use automatic air brakes. A straight-through electro-pneumatic brake is used. The exhaust braking principle adopted by the automatic air brake is higher in terms of applicability and safety, but it is not as good as the straight-through electro-pneumatic brake in terms of operabi...
