![]() ![]() Thus the intendedpurpose ofthis report is to present different scenarios of the Ultrasonic monitoring railway tracks (full crack, minor crack and zone fully monitored) for Transnet (RSA,Johannesburg) and to itemize several design materials (transmitter, receiver, PLC, GSM, etc.). ![]() Railway tracksarethen subjectedto very large forces even when operated undernormal traffic conditions and exposed to potential extremes of temperature from ourenvironment. Ultrasonic system provides early warning of anomalies within the railway track this provides mitigation against the risk of derailment due to a broken rail whereby some common rail defects include squats, wheel burn, inclusions and surfacecracking where 90% is due to cracks on the rails either due to natural causes or due to antisocial elements. ![]() Figure 4 Transmitter Tx sending Ultrasonic pulse received by Rxįigure 5 Transmitting power versus frequencyįigure 7 Working mechanism indicating missing track or full crackįigure 8 Working mechanism indicating minor crack interfering with the wave ![]()
