Method and system for checking rail fracture

Abstract

The present invention provides a rail fracture inspection method, comprising: controlling the transmitter to send electrical signals to N vibration generators, wherein N is an integer greater than 0; controlling the vibration generators to convert the electrical signals into vibration signals, and Delivered to the rail; control the M vibration sensors corresponding to the vibration generator to convert the received vibration signal into an electrical signal and send the electrical signal to the receiver, wherein M is an integer greater than 0; according to the The electrical signal is used to determine whether the track is broken. The track fracture inspection method and system of the present invention can realize real-time and high-efficiency detection of track fracture, and can detect multiple components in the turnout area without being interfered by electrical circuits and track signals; the control method and equipment layout are flexible, saving costs, It is convenient for control and management; the system architecture is safe and stable, with high accuracy.

Description

technical field [0001] The invention belongs to the field of rail transportation, and in particular relates to a method and system for rail fracture inspection. Background technique [0002] As an important inspection item involving the safe operation of rail lines, track fracture inspection has attracted increasing attention. For the section rail breakage, the method mostly used in the prior art is to use the ZPW2000A track circuit equipment to detect whether the rail breakage fault of electrical connection and disconnection occurs by using the electrical signal. The method is: the transmitter sends an electrical signal, and the electrical signal is received by the receiver after passing through the rail; if the rail is broken, the electrical signal cannot reach the receiver through the rail, and a fault is reported at this time. However, for the turnout section line, due to the electrical short circuit caused by the sliding bed plate and other equipment on the line, the e...

Problems solved by technology

However, for the line in the turnout section, due to the electrical short circuit caused by the sliding bed plate and other equipment on the line, the electrical signal cannot be used for detection. At present, the periodic flaw detection and patrol inspection of the public works department are mostly required to realize the inspection of the rail fracture.

[0003] Periodic flaw detection and patrol inspection mainly use ultrasonic flaw detection vehicles or manual inspection methods. The advantage is that the test accuracy is high and early cracks in the rail can be found; however, the detection speed is slow, the efficiency is low, and it takes up a lot of skylight time, so it cannot be done. 24 / 7 testing
