Long-distance steel rail damage detector

Abstract

The invention provides a long-distance steel rail damage detector, belonging to the technical field of railway safety detection. The long-distance steel rail damage detector comprises a synchronous acoustic wave generating module, an acoustic wave receiving module and an ultrasonic analysis module, wherein the synchronous acoustic wave generating module comprises an ultrasonic transducer, an ultrasonic generator, a first single-chip microcomputer synchronous controller, an echo detection analyzer and a first wireless data transmitter, a synchronous control module comprises an acoustic emissionsensor, an amplifier, a second single-chip microcomputer synchronous controller and a second wireless data transmitter, and the ultrasonic analysis module comprises an acoustic emission capture card,an ultrasonic rail condition monitoring module, an acoustic emission rail condition monitoring module, a high-speed rail stress monitoring and stress change analysis module, a rail fracture / damage comprehensive analysis and early warning module and a display. The detector directly feeds ultrasonic energy into a steel rail by utilizing ultrasonic propagation characteristics on a solid surface, soas to analyze the running situations of a road segment, and timely report the situations of rail fracture and crack.

Description

technical field [0001] The invention belongs to the technical field of railway safety detection, and in particular relates to a long-distance rail damage detector. Background technique [0002] At present, the methods used for railway rail detection mainly include the method of using rails to transmit electrical signals and ultrasonic flaw detection. These methods are powerless for the detection of rails in the railway fork area, and cannot find the rail fracture or damage in the fork area in time. There are the following inconveniences: [0003] Use rails to transmit electrical signals to form an open circuit in the fork area, and the state of the rails in this area cannot be detected; [0004] Although ultrasonic flaw detection can detect the fracture of the rail, it cannot be monitored on the rail for a long time, and the fracture and damage of the rail cannot be detected in time; [0005] Additional electrical signal detection in the railway crossing area can cause inte...
