Railway network maintenance: critical issue for

safety.Lack of maintenance 39% of accidents.

7ni.com

The first mobile robot for automatic railway switch inspection

Flexibility

• replaces multiple manual tools for

different measures

• used both on railroad switches and on

tracks

Automation

•

analyzes more switches in series• reduces times vs manual survey

Objectivity

• increases accuracy of the measurement

• avoids personnel errors in test plans

Safety • increases safety for operators

• guarantees railways safety

Cost

• cheaper compared to diagnostic

wagons

| NI Labview system design software allowed a rapid prototyping during the

various cycles of product consolidation, shortening the release times. It was alsouseful to create a good looking, intuitive graphical user interface (GUI) for the

field operators.

| NI Vision toolkit was at the basis of the Felix brain, leading to the creation of non

contact measurements algorithms; these have been used for the tridimensional

information extraction from the railway switches.

| Report Generation toolkit was also fundamental to show to the Customers afinal synthesis of the test plans.

| The SW engineering tools (requirement gateway, VI analyzer toolkit, desktop

execution trace, unit test framework) gave a support for the data integrity and

security achievement.
