DESCRIPTION – CATENARY DIAGNOSTIC SYSTEM WITHOUT CONTACT
Its mission is to diagnostic overhead contact lines (catenary) by recording the height and the offset measures. The height and the stagger of the catenary are measured without contact by artificial vision.
- Warning alarms in real time.
- Poles are detected automatically by laser technology and software.
- Compensation of the suspension by potentiometer or LVDT.
- Record the GPS position and the odometry of the train.
- Recording and watching a video on inspection. Take inspection samples every 0.25 m and stored in database.
- Calculation of the slope between poles, Pantograph arm, Sag and against-sag.
- Allows viewing, printing and exporting the inspection data to Excel.
MAIN FEATURES
