Train test platform

Abstract

A train test platform (101) for integration testing of actual train components of a multiple car railway train and a method to test such actual train components ahead of production of the first actual real train or without the need of an actual complete train is provided. The test platform (101) comprises a supervisor unit (119) and several car units (111 to 118) linked by a reflective memory system (137). The actual components to be tested are installed in instrumentation units of the respective car units (111 to 118). The instrumentation units provide break-out interfaces for connecting the actual train components to a train communication system (136) comprising the wiring, bus systems, power supplies etc. that are functionally identical to the communication system (136) in the actual train. Further the instrumentation units simulate those components not being present physically in the respective cars to provide the signals produced by theses components and to react on signals designated for these components. Testing is performed by monitoring and or manipulating signals at the break-out interfaces in real-time. All testing is controlled by the supervisor unit (119) using the reflective memory to exchange information with the platform components in the respective car units (111 to 118).

Description

technical field [0001] The invention relates to a train testing platform, especially for the integrated testing of electrical, electromechanical and / or electro-pneumatic train systems and components. Background technique [0002] The complexity of modern rail trains has increased dramatically over the past few decades. Many systems and components today are controlled and interconnected by communication systems including wires and buses. In trains that include multiple cars, it is important to test the individual train systems and components not only for their functionality as individual systems, but also for their functionality as components of an interconnected integrated train system. [0003] To date, test stations or test platforms for the independent testing of individual train systems have generally been set up. US 6,269,319 B1 also discloses a reconfigurable integrated test station for multiple vehicle components of a single vehicle (eg aircraft). Test stations are...

AI Technical Summary

Problems solved by technology

However, simulating all other components that may affect the UUT is in some ways tedious and time-consuming, and also error-prone

Unintended influences and disturbances are often not detected due to lack of simulation of components that do not usually "mimic" unintended behavior

The problem becomes more complex when testing not only a group of components of a single vehicle, but also a multi-car unit similar to a railroad train
