Automatic inspection of jammed brakes
In order to test brake systems of wagons and railcars, test benches are used where infrared pyrometers or thermal imaging cameras are installed. These temperature measuring devices detect the passing train and measure laterally on the brake systems. Due to friction, jamming brakes develop high temperatures, which are detected by infrared temperature sensors. Non-contact temperature measurement enables automatic identification of those railcars and wagons with jammed brakes and marking them for maintenance.
