- Abstract
Most single-track railway sections in the uninhabited area are not equipped with track circuits, that is, there is no real-time broken rail detection capability. With the popularization of seamless steel rails and the increase of speed-raising and heavy-load trains, the rail is more prone to crack and break, and the demand for operation and maintenance of detecting broken rail is increasing. Based on the principle of track circuit, combined with direct digital frequency synthesis technology, long-distance radio communication technology and digital power amplifier technology, a low-power, easy-to-deploy real-time broken rail detection system is designed in this paper. Compared with the current common detection technology of broken track in China, this system is more suitable for the railway in uninhabited area and can greatly reduce the pressure of operation and maintenance.
