Catenary Measurement

FVM képernyőmentés.png

UniLaser family

High-speed, contactless catenary measurement system

  • Measures the height and stagger of the catenary with an accuracy of ±1 cm

  • Provides real-time synchronised view of multiple sensor readouts along with camera images and location data

  • Alerts for defects

  • Complex inspection software is available for post-measurement evaluation in the office

  • Various export types are available, including MS Excel

  • Maximum measuring speed is up to 120km/h

Parts of the measuring system:

  • A LiDAR sensor fixed on top of the vehicle

  • GPS (with submeter accuracy on request)

  • A temperature gauge and an acceleration gauge

  • A dome camera observing the environment and catenary-pantograph interaction

  • The central electronics and a PC in the vehicle

Unilaser family

UniLaser 15

Catenary measurement for maintenance work

  • Safe, simple, hardened contactless measuring system which can be installed on catenary maintenance vehicles

  • It measures and displays the height and stagger of the catenary with an accuracy of ±1 cm

  • Provides real-time measuring data

  • Multiple wireless displays are available for the work-crew to enable fast and accurate adjustment of the catenary wire

Complex catenary diagnostic

Catenary and pantograph diagnostic system for measuring in normal condition

  • It is a complex system for collecting data and recording pictures to reveal overloads that cause the pantograph to break or to heat up, incorrect catenary geometry and to track down the deterioration of catenary

  • The measuring program records and displays the following data:

  • position of the catenary 

  • 2D forces  influencing on the pantograph

  • 3D acceleration of the pantograph

  • current and voltage measured on the pantograph

  • records of the thermal imager camera showing the ambience of the pantograph

  • records of the normal camera showing the ambience of the pantograph

  • records of 2 quick cameras showing the connection of the pantograph and the catenary 

  • By setting thresholds limits, the measuring program indicates the location of defects and the evaluating program collects them
