Flat Wheel Detection System based on fibre optic technology
WILD - Wheel Impact load detector
WIM - Weighing in motion
Detection of wheel defects (eccentric wheels, flat sections)
Fibre optics technology (special, measuring technology)
No blind spots
Simple to install and maintain
Immune against electromagnetic interference (thanks to fibre optic technology)
Directly measures force at origin (DMFO)
Records train weight, and monitors overloads and asymmetrical loads
Packable (need not de-install sensors for packing ballast
Ballast analysis System (BAS)
Integrated auto-calibration and self-check functions
Overlapping = OFM
The measurement of the sensors overlap (OFM) for a complete scan of the wheel, without any blind points
Example of a V7 system (Wheel diameter 0,8m and measurement area 4,8m) :
6,6 m long monitoring zone with V 11 (11 sensors on each side) for scanning a wheel twice successively (wheel diameter 1m).
Distance between F sensors (7/8) and cabin may exceed 2000 m.
Data is transmitted via Ethernet (7/8).
1= WC1 Cable, 4= WC4 , 2 & 3 = Fibre optics cable 9 = Aguila rack, 10 = cabin
Example of an installation for Tram
Example installed at High Speed line ( speed up to 300km/h )
