Test method and device for indirect braking of a rail vehicle

By independently setting up a local braking control unit in the rail vehicle train control unit, indirect braking tests without relying on the train manager were realized, solving the problem that tests could not be carried out under train manager failure, and improving fault location and maintenance efficiency.

AI Technical Summary

Technical Problem

In the existing technology, the testing of the indirect braking function of rail vehicles relies on the train manager, which makes it impossible to carry out the test normally when communication is interrupted or logic deadlock failure occurs, and the status of the indirect braking function cannot be confirmed in a timely manner.

Method used

By independently setting up a local braking control unit in the train control unit, a dedicated test control path is formed that does not rely on the train manager. The local braking control unit is scheduled to perform train pipe connection, indirect braking application, release, pressure holding and ventilation tests, obtain and determine the results of individual tests, and finally determine the comprehensive test results.

Benefits of technology

It enables indirect braking tests to be carried out normally even in the event of a train manager failure, allowing for timely confirmation of functional status and improving fault location efficiency and targeted maintenance.
