Scanning Solution for Trains

TREX-UVSST

TREX-UVSST is an inspection solution that helps technical inspectors to quickly and safely inspect the entire chassis and lower sides of wagons.

This solution uses the latest digital camera technology, LED lighting and Artificial Intelligence (AI) image processing algorithms.

When a train passes through a checkpoint, the solution :

Captures high-resolution images of the chassis and side parts of each wagon.
Automatically detects and identifies the position of certain sensitive parts : bogie, spring, buffer…
Automatically recognizes each wagon’s registration number…

Thanks to the high-definition images produced and automatic detections, the solution helps operators to carry out a digital technical pre-inspection of each wagon. Then, the operator can visualize and trace areas showing anomalies, non-conformities, damage or wear, before carrying out an on-site inspection. This optimizes technical inspection time.

TREX-UVSST is the essential tool to support the wagon inspection and identification process at terminals or rail maintenance centers.

ANY QUESTION?

The TREX-UVSST solution is designed to :

Capture high-resolution images of the entire convoy undercarriage.
Read wagons and containers codes (option).
Automatically recognize characteristic parts of a wagon by AI.
Automatically detect particular equipment, anomalies, wear points, part variations through stored reference images.
Run specific analysis of the detected parts (contat us)
Alert operator in case of any need of maintenance detected.
Allow operator to efficiently and safely inspect the entire train at a railway, multimodal, maintenance or logistics terminal entrance.
Archive all information collected during the passage of trains in an SQL database.
Integrate with external systems : maintenance systems …
Be efficient 24h/24.
Withstand various climatic constraints, vibrations, etc.
Offer a powerful Software Suite with a pleasant and intuitive graphic interface.

data

Export of all collected data (date, time, site, track, inspection images, wagon number, detected elements, container code, registration…) at checkpoints to an SQL database (PostgreSQL, Microsoft SQL Server…) via the TREX secure Web Service, or to XML files, or to any other system via a specific export plugin.

efficiency

The TREX-UVSST solution is fully automatic system, efficient 24 hours a day.

For optimum inspection, train speeds of up to 20km/h are possible.
