Problems solved by technology

[0003] Due to the vast territory of our country, it is costly, complicated to construct, long construction period and difficult to maintain to establish a whole line monitoring system along the railway
Moreover, the detection device is set on the ground, and the wheel-rail contact status can only be known when it reaches the designated monitoring location, so real-time monitoring cannot be implemented

Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0043] See attached figure 1 As shown, the present invention discloses a wheel-rail state detection method, which aims to realize real-time monitoring and detection of trains in running state by using an online detection method. The method includes:

[0044] S101), respectively setting image acquisition devices on the left and right sides of the train bogie;

[0045] S102), real-time collection of real-time image information between the left wheel rim and the left track of the train, and between the right wheel rim and the right track;

[0046] S103), collecting and detecting the image information of the surface state of the train rim;

[0047] S200), identifying the left wheel rim, the right wheel rim, the left track, and the right track in the real-time image information, and calculating the positional relationship between each wheel rim and the tr...

Abstract

The invention relates to a train wheel-rail state detection system and method. Image acquisition devices are arranged on the left side and the right side of a train bogie respectively, and image information between a left wheel flange and a left rail and between a right wheel flange and a right rail of a train is acquired in real time; the left wheel flange, the right wheel flange, the left rail and the right rail in the real-time image information are recognized through a processor, and the position relation between the wheel flanges and the rails is calculated according to the real-time image information; the position relation between the wheel flanges and the rails is output through an output device. By means of the system and method, the matching state between the wheel flanges and the rails of the train can be monitored in real time, the operation abnormity can be found in time, the fault detection rate is increased, and the safe operation of the train is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of railway safety detection, and in particular relates to a train wheel-rail state detection system and a detection method. Background technique [0002] Safe operation is the most important thing in the design and operation of rail trains, and the stability of the bogie system is one of the main issues in the safe operation of trains. Once the system is snaking and unstable, its running quality will deteriorate sharply and the running stability will be greatly reduced , and even lead to derailment. In order to detect the state of the wheel and rail in real time, Chinese patent ZL200580024026.9 discloses a device for detecting the serpentine shape and angle of attack of the rail vehicle wheel set, which is mainly achieved by adding real-time monitoring on the ground on both sides of the track The detection device for the running state of the wheel and rail. When the train passes by the detection device, the...
