摘要: Method for monitoring at least one point system of a railway network comprising the steps of placing several sensors in correspondence of said at least one point system; acquiring from said sensors current and voltage signals of a point machine during a maneuver; and segmenting the signals of the maneuver according to different predetermined phases of movement. Then extracting predetermined features from each segment; comparing the extracted features with a set of predetermined values which represent a “healthy” maneuver, thus obtaining a global indicator representative of the conditions of the maneuver at the point system; and comparing said global indicator with a failure threshold, and if it exceeds said failure threshold, detecting a failure in the point system.
