Vehicle air supply pipeline control system and rail vehicle with the system

Abstract

The invention discloses a vehicle air supply pipeline control system, comprising: a main air duct branch, wherein the main air duct branch comprises a main air duct first sub-branch and a main air duct second sub-branch; the main air duct branch comprises a main air duct first sub-branch and a main air duct second sub-branch. A train pipe branch comprising a first sub-branch of the train pipe anda second sub-branch of the train pipe; The auxiliary air cylinder branch comprises a first sub-branch of the auxiliary air cylinder and a second sub-branch of the auxiliary air cylinder; A pressure switch for detecting the pressure of the main air duct, wherein when the pressure of the main air duct is greater than or equal to the first preset value, the pressure switch controls the main air ductbranch, the train duct branch both supplies air to the air spring air cylinder and the living air cylinder, and the auxiliary air cylinder branch stops supplying air to the air spring air cylinder andthe living air cylinder; When the total duct pressure is less than the second preset value, the pressure switch controls the train duct branch or the auxiliary duct branch to supply air to the air spring duct and the domestic duct. The control mode of the system is simple, and the switching of the air supply mode can be realized quickly and safely. The present application also discloses a rail vehicle comprising the above-described system.

Description

technical field [0001] The invention relates to the technical field of rail transit, and more specifically, to a vehicle air supply pipeline control system. In addition, the present invention also relates to a rail vehicle comprising the above vehicle air supply pipeline control system. Background technique [0002] In recent years, with the development of vehicle technology, a large number of air springs, sliding doors and toilets have been used in railway passenger vehicles. [0003] In order to adapt to the increasing air volume of vehicles and avoid abnormal movement of vehicle brakes caused by fluctuations in train pipe pressure, new models of passenger vehicles are equipped with double-pipe air supply pipes, namely the main air pipe and the train pipe, and the main air pipe is used first. For wind. [0004] Each vehicle is equipped with an air circuit control box. By operating the 6 manual plugs on the air circuit control box, the single / double pipe air supply mode s...

AI Technical Summary

Problems solved by technology

[0004] Each vehicle is equipped with an air circuit control box. By operating the 6 manual plugs on the air circuit control box, the single / double pipe air supply mode switching, door closing car setting, air spring air cylinder or living air cylinder air supply isolation can be realized. / Double-pipe air supply mode switching operation is relatively cumbersome, and each car needs to operate 4 plug doors to achieve the above switching. However, a passenger train usually consists of 16 cars or more, and the control device is complicated. In addition, considering the passenger compartment air Tightness and equipment layout, the air circuit control box is arranged outside the car body, and it cannot be operated during operation or when the line regulations do not allow getting off the car, posing a safety hazard
