DETECTION OF FLAWS IN RAILS BY AUTOMATED DIGITAL INTERPRETATION OF PATTERNS IN THE ULTRASONIC INSPECTION SIGNALS

The railways of several countries now use arrays of ultrasonic probes on moving vehicles for inspection of rails. The vehicle used by British Rail has equipment to enable recording of all of the ultrasonic signals on 35 mm film for subsequent interpretation, formerly visually. A digital computer system has been developed for automated scanning and interpretation routines have now been incorporated in an all-digital system using the same vehicle. The new system includes a computer installed on the test vehicle together with specialized electronic instrumentation for digital proprocessing of the ultrasonic signals and a magnetic tape unit.
