Train Control Systems

Test systems for impedance measurements on inductive rail components for safety-related train control applications.

Application Description

The test system is used for measuring impedance and for tuning oscillating circuits on inductive modules; it is based on LXI instrumentation for high mix/low volume production, and as a repair station. The DUTs to be tested are predominantly employed in railway traffic technology, e. g. for counting axles, as well as for communications.
The system is equipped with a customer-specific 19" switch panel for connecting calibration adapters, adapters for self-tests and test adapters. The work area is designed to be free of metal, thereby supporting the precise calibration and measurement needs of oscillating circuits. The system has an integrated sweep generator which includes a broadband multimeter for impedance measurements. Occupational safety is enforced by a light curtain.

The instruments are integrated into a shelf top structure, thereby providing ample workspace for manual process steps. LXinstruments also implements customized test systems which cater for the precise measurement requirements of the application.

Special Features

In recent years, systems with this type of design have already been employed as a successful platform for a variety of applications and tests.

Customer-specific Software

The test libraries were developed to cater for the requirements of the relevant instruments; LabVIEW was used to design and enhance the application-specific interactive work steps.  The user interface was specifically customized for the customer's requirement profile. The test database was implemented based on a Microsoft SQL Server.
