Rail detection system and method

Abstract

The invention relates to the field of rail detection, in particular to a rail detection system. The rail detection system is characterized by comprising sound wave receiving equipment, sound wave transformation equipment and terminal management equipment, wherein the sound wave receiving equipment is arranged below railheads of the rails and used for receiving sound wave which is generated when train wheels collide the a pair of parallel rails; the sound wave transformation equipment is arranged above rail bases of the rails; the sound wave receiving equipment and the sound wave transformation equipment are connected through sound wave transmission equipment which is arranged on rail webs of the rails; the terminal management equipment receives a digital signal transmitted by the sound wave transformation equipment through a wireless transmission equipment; the terminal management equipment comprises a signal processing module and a radio frequency module connected with the signal processing module; and the sound wave receiving equipment is shaped like a funnel with a big open end and a small open end. The invention also provides a rail detection method for detecting by using the rail detection system. By the rail detection system and the rail detection method, rail damage can be detected on line during normal operation of the train, and the detection efficiency is increased.

Description

technical field [0001] The invention relates to the field of rail detection, in particular to a rail detection system and method. Background technique [0002] At present, rail inspection vehicle technology is widely used in rail non-destructive testing. This detection system mainly integrates ultrasonic and electromagnetic induction detection technologies and optical sensors on the rear-mounted rail inspection vehicle platform, and uses ultrasonic transmitting and receiving equipment to emit ultrasonic waves. Receive the reflected ultrasonic wave, and determine the damaged part of the rail by analyzing and comparing the changes of the waveform. The above method requires an ultrasonic emission source to perform detection. When the train is running normally, since the train continuously hits the rails to emit sound waves, if the ultrasonic generator also emits ultrasonic waves for detection at the same time, the sound waves of the train hitting the rails will interfere with t...

Problems solved by technology

The above method requires an ultrasonic emission source to perform detection. When the train is running normally, since the train continuously hits the rails to emit sound waves, if the ultrasonic generator also emits ultrasonic waves for detection at the same time, the sound waves of the train hitting the rails will interfere with the detection of the rails. The rail detection system in the prior art detects when there is no train running on the rail, and cannot realize online detection when the train is running normally
