Abstract: 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.

Abstract: The invention relates to a health status assessment method for a transport vehicle automatic or semi-automatic access device comprising at least one leaf suitable for being actuated by a kinematic chain including at least one motor supplied with electricity and having an associated angular position and/or rotation speed encoder and at least one switch. Said method includes steps, for at least one actuating cycle of the kinematic chain between a first and a second position among the open and closed positions and a second position, consisting of: during one said cycle, acquiring information relative to the kinematic chain comprising at least one piece of information representative of the electrical energy consumed by the motor, and/or position and/or speed information provided by said encoder and/or binary information indicating positions of switches, dividing said cycle into a plurality of functional segments based on said acquired information, calculating at least one descriptor value per functional segment, establishing a health status diagnosis comprising a degradation detection as a function of at least part of said calculated descriptor values.
