Computer implemented method for determining railway vehicle movement profile type of a railway vehicle movement profile and controller of a track circuit system

Computer-readable non-transitory storage medium comprising instructions, which when executed by a computer, cause the computer to carry out the following:

• obtaining a railway vehicle movement profile, wherein the railway vehicle movement profile comprises a sequence of measured transmitted currents of a transceiver of a track circuit with respect to the time;
• normalizing the railway vehicle movement profile;
• extracting one or more features from the normalized railway vehicle movement profile;
• determining the distance of the extracted features with respect to each centroid of a railway vehicle movement profile type determined in a classification process;
• and
• assigning the railway vehicle movement profile to the railway vehicle movement profile type with the closest centroid.

Controller of a track circuit system, the track circuit system including a transceiver being connected to a pair of rails of a railway track and the controller receiving from the transceiver measured transmitted currents, wherein the controller is adapted to:

• obtain a railway vehicle movement profile, wherein the railway vehicle movement profile comprises a sequence of measured transmitted currents of a transceiver of a track circuit with respect to the time;
• normalize the railway vehicle movement profile;
• extract one or more features from the normalized railway vehicle movement profile;
• determine the distance of the extracted features with respect to each centroid of a railway vehicle movement profile type determined in a classification process;
• and
• assign the railway vehicle movement profile to the railway vehicle movement profile type with the closest centroid.
