[0002] As my country's railway construction develops rapidly, the requirements for its safety are becoming higher and higher and more stringent. Rails are the most important part of railway construction. Due to long-term exposure to the open air, wind and sun, and repeated friction, extrusion and impact of locomotive wheels, it is very likely to break somewhere. In order to repair the damaged track in time to avoid major accidents and reduce the possibility of tragedy, the fracture detection must have the characteristics of less false alarms, fast response, and less impact by environmental factors. Therefore, a rail fracture electronic detector is used;

[0003] Currently, the railway uses manual search method to confirm the location of rail cracks. Due to the long track line, small rail crack width and great influence of outdoor climate, manual search for rail cracks is inefficient, easy to miss, and greatly affected by environmental factors, making it inefficient when used. Summary of the invention
