INSPECCION AUTOMATICA DE HILO DE CONTACTO POR VISION ARTIFICIAL
The object of this project is to develop an automated system for measuring contact wire wear in mining railway systems using electric traction. This system would employ optical devices and use artificial vision techniques, testing the feasibility of this inspection system. A prototype sensor has been designed, based on illumination with structured light (laser) and a matrix CCD camera feeding data to a computer controlled image processing system. The whole system is mounted on a specially adapted wagon towed along the stretches of track inspected. The system provides readings of wire wear and its position with regard to the track. This sensor is mounted on a mobile structure with two degrees of freedom to enable the sensor to track vertical and horizontal wire displacements. Given the type of installations where this system has to operate, and as this is a prototype, it has been built without protection against explosive atmospheres. Tests performed in situ in the mine and in the laboratory have demonstrated system feasibility and effectiveness, while also detecting certain limitations and possible improvements for future development work. The possibility of using the system for conventional above-ground railway lines has also been investigated.
