Abstract (en)
[origin: WO2009054566A1] A system for detecting wheel profile defects in a railway vehicle is disclosed. Magnetic field measurement means obtains information about a magnetic field in the vicinity of each wheel of a railway vehicle. Data collection means reads the presence or absence of defects in the wheel in the form of magnetic images using the information about the magnetic field obtained by the magnetic field measurement means. Magnetization means magnetizes the wheel. A magnetic lens focuses a magnetic field on the profile of the magnetized wheel. A magnetic sensor array converts the information about the magnetic field, focused using the magnetic lens, into electric signals. An Analog/Digital (A/D) converter converts the information about the magnetic field, converted into the electric signals using the magnetic sensor array, into digital signals.
