Pantograph Parameters

This module realize a 3D measurement by analyzing the images of the trace obtained on the surface of the pantograph with a collimated laser beam acquired by a digital matrix camera.
The Morph & Wear module surveys:

• the pantograph head as 3D point cloud for identifying defects of the shape of the head by comparison with a 3D model or with previous acquisitions of the same pantograph;
• the upper surface of the contact strip for measuring its wear and lack of material from the contact stripes.

The Y-Tension Module measures the vertical position of the contact wire in a time span around the transit of each pantograph, the vertical position is then used for determining the pressure against the contact wire. The acquisition starts when the train enter in the monitored area and stop when it exits.
Using the signal of the pantograph presence it is possible to save the data related to predefined time span extended before and after the pantograph transit.
