Abstract

The embodiment of the invention provides an air braking system and a control method of the air braking system. The air braking system comprises a redundancy channel, a distribution valve and a braking vitrified clay pipe, wherein one end of the redundancy channel is connected with a main blast line and the other end of the redundancy channel is connected with the braking vitrified clay pipe; when a railway locomotive is emergently braked, the redundancy channel receives main blasts in the main blast line; when the air pressure of the main blasts received by the redundancy channel is higher than the air pressure of compressed air in the braking vitrified clay pipe for a preset threshold value, the redundancy channel conveys the received main blasts into the braking vitrified clay pipe, and the air pressure in the braking vitrified clay pipe is increased. The distribution valve is connected with a control vitrified clay pipe and used for inflating the braking vitrified clay pipe with the compressed air, so that the air pressure in the braking vitrified clay pipe is increased. When the value of the air pressure in the braking vitrified clay pipe is not smaller than a preset numerical value, the railway locomotive is braked.

Description

technical field [0001] The invention relates to the field of brake control of railway locomotives, in particular to an air brake system and a control method thereof. Background technique [0002] Air brake is one of the braking methods of railway locomotives. It uses compressed air as the driving force for braking, and changes the pressure of compressed air to control the braking of trains. The air brake system of railway locomotives is to ensure the safety of rail traffic. The key components. [0003] In the prior art, the air braking system of railway rolling stock controls the air pressure of the compressed air entering the brake cylinder pipe through the distribution valve, that is, the air braking system of railway rolling stock controls the air filling of the brake cylinder pipe through the distribution valve Or air exhaust, when the railway locomotive needs to brake, the control distribution valve will charge air into the control cylinder pipe, and when the air press...
