Longitudinal Defect Detection System - LDDS

LDDS inspects infrastructure devices that reside in the vertical plane along the track longitudinal axis such as catenary rope and contact wire, droppers, fixed points, insulators. It recognises changes on the infrastructure devices.

The analysis can also be performed taking into account data coming from an catenary geometry measurement system for cross-correlation of measured data.

Composed by two acquisition units (left and right units respect to catenary wires), the system is based on high speed linear cameras and a laser lighting module. High performance, smart vision algorithms extract relevant parameters and defects such as:

• Detection of changes and corrosion on main catenary infrastructure devices
• Detection of broken and/or bulged droppers
• Detection of dropper slant
• Detection of broken or missing insulator parts
• Inspection of contact wires, messengers and feed lines: corrosion on the wires and the ropes
