Abstract

In the field of rail systems technology, the invention relates to an acoustic method that can detect heavy rainfalls, floods, landslides and under rail washouts in real time and before the train arrives, on the line that may threaten the safety of railway traffic, by employing acoustic signal generator and acoustic signal sensor modules connected to the rails in the rail fracture or crack detection system, which can be used in the detection of railway rail failures. The invention, in particular, relates to an acoustic method that allows the receiver and transmitter to exchange data between them after they are fixed at certain points, not by moving them on the line, but by sending a certain acoustic signal from a fixed point and starting the detection process. It provides the detection and evaluation of the original acoustic signal coming from both the same point and other points with a certain change and/or the acoustic signal caused by heavy rainfall, flood, landslide and under-rail washouts.
