Software OVHWizard

Software of the OVHWizard

The OVHWizard software serves for:

Parameterisation of the measuring system
Measured data recording, saving and evaluation
Graphic online display of the measured values
Online display of the camera images of the contact wire
Transfer of the measured data to customer-specific software
Transfer of the data to the FMA software
Data processing in the postprocessing









All vehicle parameters such as wheel diameter, distance pulses per wheel revolution or assembly height of the OVHWizard above the top edge of the rail are entered and saved with the Vehicle Set-up. With these parameters, the position of the measurement system in relation to the rail is determined after mounting or calibrated automatically before a measurement run.

The distance travelled is measured by a light barrier and reflectors mounted on the wheel or by reading in the vehicle-internal pulses.


The measurement is displayed graphically to the operator online during the measurement. The height and stagger of the contact wire and the catenary wire - providing this is in the set measuring range of the system - are displayed together with the set tolerance limits. The camera image with the measured values is displayed additionally as an option.

Ten events (e.g. points, crossing, bridge, etc.) can be programmed with the computer function keys and can be set during the run. The software offers the possibility of viewing the measurement again after the measurement.

The analysis function offers the possibility of evaluating the measurement automatically. Pole positions are detected here automatically. The height and stagger of the contact wire are shown as measured values at these poles and in the centre of the span length step. The gradient and the span length step are also determined and specified.


At the end of the analysis it is possible to create a report or to export the data to Excel.
