Monitoring system for at least one plurality of homogeneous devices of at least one railway vehicle

Monitoring system for at least one plurality of devices, which are homogeneous, of at least one vehicle, wherein a functional state of each device is represented by a respective value of at least one operating quantity common to said plurality of devices;

• the monitoring system comprising:
• at least one control means arranged to acquire, in a temporal succession of acquisition instants determined on the basis of a predetermined acquisition period, a plurality of values of said at least one operating quantity;
• each value of said plurality of values being representative of the functional state of a respective device of said at least one plurality of devices in one acquisition instant;
• diagnostic means arranged to receive, through a communication means, the plurality of values acquired in one acquisition instant, and to detect an operating anomaly or a request for maintenance by at least one device of said at least one plurality of devices as a function of a comparison, for each acquisition instant, of said plurality of values received with at least a range of reference values;
• the range of reference values comprising a reference value and a neighborhood of values associated with said reference value;
• the reference value being determined by said diagnostic means as a function of at least two values of said plurality of values acquired in one acquisition instant.
