An electro-pneumatic control unit of a locomotive braking system with a standardized module

Abstract

The application discloses an electro-pneumatic control unit of a locomotive braking system with standardized modules, including: a train pipe control module, a brake cylinder control module, a backup control module, an air brake valve module, an auxiliary function module, an electrical interface module, Filter, integrated air circuit board. The train pipe control module, brake cylinder control module and backup control module are three core intelligent standardized modules of the electro-pneumatic control unit. The hardware composition and internal air circuit principle of the three modules are completely consistent, and they are composed of exactly the same pneumatic valve Class components and electronic control boards. The structural composition of the electro-pneumatic control unit of the present invention is convenient for later inspection and maintenance; when the locomotive is set for fire-free return, the function of "one-key fire-free" is realized, which saves operation and improves efficiency; the design of removing the rear air cylinder prevents the air cylinder from being difficult to replace, etc. Problems; prevent damage to each pressure measuring point during use and transportation.

Description

technical field [0001] The invention relates to the technical field of locomotive braking control. More specifically, the present invention relates to an electro-pneumatic control unit of a locomotive brake system with standardized modules. Background technique [0002] The locomotive brake control system is one of the most important components of the locomotive, which is related to the travel safety of the locomotive, vehicles and passengers. The electro-pneumatic control unit is the core component of the locomotive brake control system, which can execute the instructions of the brake controller, brake display screen or other related systems of the locomotive to achieve the braking function requirements. At present, the most mainstream locomotive braking systems in the world are mainly German Knorr-Bremse CCBⅡ braking system, Faiveley's Eurotrol braking system and domestic CAB-A and CAB-B braking systems. These types of locomotive braking systems The electro-pneumatic con...

AI Technical Summary

Problems solved by technology

[0003] 1. The hardware composition of each module of the electro-pneumatic control unit is completely inconsistent, and the core intelligent modules such as the train management control module, brake cylinder control module and backup control module cannot be interchanged. There are deficiencies in maintainability and other aspects, which is not conducive to Later inspection and maintenance of locomotive operating units;

[0004] 2. At present, the locomotive brake systems at home and abroad have not realized the function of "one-button no-fire", that is, all brake systems need to operate two or more buttons or plugs to realize the setting of the locomotive no-fire mode. Weaknesses in usability;

[0005] 3. The air circuit board of the electro-pneumatic control unit is equipped with multiple air cylinders such as the working air cylinder and the functional air cylinder. When the electro-pneumatic control unit is integrated into the brake cabinet, the position of the air cylinder will be between the electro-pneumatic control Between the unit integrated air circuit board and the air pipeline of the brake cabinet, when there are many pipelines and the air cylinder leaks air, or because the maintenance space at the rear of the electro-pneumatic control unit is small after the brake system is installed, it is difficult to replace the air cylinder. There are deficiencies in maintainability, etc.;

[0006] 4. The pressure measuring points of the electro-pneumatic control unit are arranged on each module, located on the outermost side of the electro-pneumatic control unit, which may easily cause damage to the measuring points during application and transportation
