1. A system for detecting roundness defects on wheels of a railway vehicle that runs on a rail circuit, comprising:

  • a. an identification system comprising a set of tags that emit radio frequency identification for the conditions of each wheel of the railway vehicle;

    b. a measuring area consisting of a single measuring point located on a section of a rail, wherein said measuring point generates a signal proportional to the deformation on the rail when a wheel arch passes over this point;

    c. a comparator system that receives the signal from the single measuring point, linearizes the signal, and detects a defect in the roundness of a wheel if the value of the mathematically processed signal exceeds a threshold deviation of a mathematical six grade parameterization; and

    d. a data network that associates wheel identification information with corresponding defect data generated by the comparator system.
