Problems solved by technology

[0004] However, the brake control system test bench in the prior art needs to be additionally connected to the brake control system under test for the brake control system to be tested as the braking situation of the system under test, such as locomotive reconnection, no fire return, etc.
As a result, the operation complexity of the test bench test process is increased, and the performance test of locomotive reconnection and non-fire return braking type is increased, which is not conducive to the automation of the performance test of the brake control system

Abstract

The present invention provides a brake control system test bench, comprising: an air inlet pipeline, the air inlet pipeline is connected to the main air pipeline of the brake control system, and a first switching valve is arranged on the air inlet pipeline; One end of the simulation pipeline is connected to the corresponding pipeline interface of the brake control system; there is at least one simulation pipeline that is a communication pipeline, and the other end of the communication pipeline is connected to the air inlet pipeline; the communication pipeline A pressure control valve is set on the road; the communication pipeline is a simulation pipeline of a train pipe. The invention does not need to provide an accompanying brake control system, which reduces the complexity of the test process of the brake control system.

Description

technical field [0001] The invention belongs to the field of performance testing of railway locomotives, and in particular relates to a brake control system test bench and a test method. Background technique [0002] The braking control system is an important part of the railway locomotive braking system. The performance of the braking control system directly affects the braking performance of the locomotive braking system and the safety of the vehicle. At present, my country's railway freight cars generally use the air brake system for braking. In order to improve the performance of the air brake system and improve the safety of driving, it is necessary to perform a performance test on the air brake control system before the air brake control system is installed and used. [0003] In the prior art, the test bench used for the performance testing of the locomotive brake control system is to connect the pipeline of the air circuit part to the corresponding pipeline interface...
