Railway locomotive vehicle and removing system and control method thereof

Abstract

The embodiment of the invention provides a railway locomotive vehicle and a removing system and a control method thereof, wherein the method comprises an electric pneumatic valve for removing a brake cylinder precontrol pipe, a brake cylinder precontrol pipe isolating valve, an electric pneumatic valve for removing a relay valve train pipe, a relay valve train pipe isolating valve and a brake control unit; the electric pneumatic valve for removing the brake cylinder precontrol pipe is connected with the brake cylinder precontrol pipe isolating valve, the brake cylinder precontrol pipe isolating valve is located on the brake cylinder precontrol pipe, the electric pneumatic valve for removing the relay valve train pipe is connected with the relay valve train pipe isolating valve, and the electric pneumatic valve for removing the relay valve train pipe is located on the relay valve train pipe; the brake control unit is used for controlling the power losing of the electric pneumatic valve for removing the brake cylinder precontrol pipe and / or the electric pneumatic valve for removing the relay valve train pipe.

Description

technical field [0001] The invention relates to the field of braking control, in particular to a railway locomotive and its air circuit control system and control method. Background technique [0002] The braking system of the railway rolling stock is used to control the running speed of the railway rolling stock, so that the railway rolling stock can stop at the designated place in time and accurately, so as to ensure the punctuality and safe operation of the railway rolling stock, and can effectively avoid the rushing of the railway rolling stock , rear-end collision and other major rail traffic accidents are the key to ensuring the safety of rail traffic. [0003] In the prior art, if the railway locomotives adopt the dual brake system, when the railway locomotive dual brake system is operated from the master machine mode to the supplementary machine mode, that is, the railway locomotive dual brake system performs master-slave When switching operations, or performing the...
