METHOD, DEVICE AND SYSTEM FOR DETECTING FAULT(S) IN A PANTOGRAPH OF A MOVING VEHICLE ON A RAILWAY

The invention relates to a method (100) for detecting defect(s) in a pantograph of a railway vehicle, said method (100) comprising the following steps: - capturing (104) at least one image of said pantograph; - analysis (106) of said image by a neural network previously trained for the detection of pantograph defect(s) from images of defect(s) previously captured; characterized in that the neural network is stored in situ at the level of the capture site, the analysis step (106) being performed in situ on said capture site. It also relates to a detection device implementing such a method, and a system and a railway line equipped with such a detection device.
